Recovering a database with a missing transaction log #microsoft #sql #server, #sql


Recovering a database with a missing transaction log

Question: We had a SAN problem over the weekend and the upshot is that one of our main databases was shut down with open transactions, but we ve lost the log file. The last working backup is two weeks old.

Is there any way to recover the database without having to resort to the old backup?

Answer: Yes, but not without consequences.

Usually when a database has open transactions and the server crashes, crash recovery will run on the affected database and roll back the open transactions. This prevents the partial effects of transactions being present in the database. If the transaction log is not available when SQL Server starts, the database will be in the SUSPECT state.

In this case, the only way to bring the database online (note that I m not saying way to make the database usable ) is to use the emergency mode repair functionality that was added in SQL Server 2005. This basically builds a new transaction log and then runs a DBCC CHECKDB using REPAIR_ALLOW_DATA_LOSS. Read more .

The problem you will have if you decide to go this route is that emergency mode repair cannot roll back any of the active transactions as it has no knowledge of what they were, because the transaction log was destroyed. This means that at best, the resulting database will be transactionally inconsistent i.e. the state of the data in the database is unknown.

For instance, there may have been a transaction that was updating some sales records in a table, and only half of them were updated before the crash and subsequent transaction log loss occurred. You ll find it very difficult to figure out what state the data is in, and how to make the database properly usable again by the application.

Emergency mode repair is supposed to be a real last resort when all other methods of recovering data have failed.

In your case, you ll have to figure out what is the lesser of two evils recovering the database into an inconsistent state, or restoring the two-week old backup. You may end up deciding to do both, and trying to piece together the data, but that will be very time consuming and problematic again, because you don t know what was happening in the database at the time that the crash occurred.

To prevent this situation in future, beef up your backup strategy to use much more frequent backups, and add a high-availability technology that maintains a real-time copy of your database such as database mirroring or SQL Server 2012 Availability Groups.

Why .NET Core Made C# Your Next Programming Language to Learn

Why .NET Core Made C# Your Next Programming Language to Learn

Get Your Apps to Customers 5X Faster with RAD Studio

For years I have read about polyglot programmers and how some new language was the new cool thing. Over time, it has been programming languages like Ruby, Python, Scala, Go, Node.js, Swift, and others. It is amazing to see what Microsoft, and the community, have done with .NET Core and how it has become the cool new thing.

The problem with many of the existing programming languages is they are good at one use case. Ruby and PHP are awesome for web applications. Swift or Objective-C are great for creating iOS or MacOS applications. If you wanted to write a background service you could use Python, Java, or other languages. Besides C#, JavaScript and Java may be the only languages that can be applied to a wide set of use cases.

It is hard for me to apply my skills to a broad set of problems if I have to learn many programming languages. It limits my job opportunities. The awesome thing about C# is the wide versatility of it that can be used for a wide variety of types of applications. Now with .NET Core working on MacOS and Linux, there truly is no limit to what you can do. We will explore this in more detail below.

Why C# and .NET Core Are the Next Big Thing

I have been playing with .NET Core for over a year now and have been very impressed with it. I have even ported a .NET app over to run on a Mac, which was pretty amazing to see in action after all these years!

Since our company creates developer tools that also work with .NET Core, I feel like we are more plugged in to what is going on. It feels like .NET Core is picking up steam fast and I predict there will be a huge demand for .NET Core developers in 2018. We talk to customers every day who are already running .NET Core apps in production.

According to the TIOBE programming index. C# is already one of the top 5 programming languages.

Top 6 Things to Know About C# and .NET Core

If you are thinking about learning a new programming language, I want to provide you some of my insights as to why C# and .NET Core should be on the top of your list.

Easy to Learn

If you have done any programming in C, Java, or even JavaScript, the syntax of C# will feel very familiar to you. The syntax is simple to understand and read. Based on the TIOBE index I posted above, there are millions of developers who could easily make the switch from Java or C.

There are lots of online resources to help you learn C#. Many are free and there are some that are low cost as well.

Modern Language Features

NET has been around a long time now and has steadily changed and improved over 15 years. Over the years I have seen awesome improvements like MVC, generics, LINQ, async/await, and more. As someone who has personally dedicated myself to the language, it is awesome to see it improve over time. With .NET Core, a lot has changed, including all of the ASP.NET stack being completely overhauled.

Here are some the top features:

  • Strongly typed.
  • Robust base class libraries.
  • Asynchronous programming – easy to use async/await pattern.
  • Garbage collection, automatic memory management.
  • LINQ – Language Integrated Queries.
  • Generics – List T , Dictionary T, T .
  • Package management.
  • The ability to share binaries across multiple platforms and frameworks.
  • Easy to use frameworks to create MVC web apps and RESTful APIs.

Versatility: Web, Mobile, Server, Desktop

One of the best things about C# and .NET is the versatility of it. I can write desktop apps, web applications, background services, and even mobile apps thanks to Xamarin. Besides C#, all I really have to know is a little JavaScript (aided by TypeScript) to hack some UI code together (which I still try to avoid!). ASP.NET Core templates even make use of Bootstrap layouts and npm for pulling in client-side libraries.

The versatility is a big deal because your investment in learning the language can be used for a wide array of things. Your skillset is highly portable. You can also jump from building web apps to mobile apps if you want to mix up what you are doing. This is a stark difference to most other programming languages that only work server side.

And let’s not forget the first class support for Microsoft Azure. It’s never been easier to get up and running and then deployed to the cloud in just a few clicks. Docker containers are also supported which makes it easy to deploy your app to AWS or other hosting providers as well.

Awesome Developer Tools

Visual Studio has always been regarded as one of the best IDEs available for developers. It is a great code editor that supports features like code completion, debugging, profiling, git integration, unit testing, and much more. Visual Studio now offers a full-featured, free Community edition.

It is also possible to write code for .NET Core as basic text files with your favorite text editor. You can also use Visual Studio Code on any OS as a great basic code editor. For those of you who will never give up your vim or emacs, you can even do C# development too. You could also install a plug-in for Visual Studio to add all of your favorite shortcut keys.

The whole .NET ecosystem is also full of amazing developer tools. For example, I couldn’t imagine living without Resharper from Jetbrains. There are dozens of awesome tools that exist, including a mixture of open source and commercial products.

Standardization of Skills

NET comes with a very good set of base class libraries. Unlike Node.js, simple string functions like LeftPad() are built in. The wide array of base classes really decreases the need for external packages. Microsoft does lean on some community projects as well, like JSON.NET, to be key libraries widely used in most projects.

Microsoft provides a very good set of patterns and practices for .NET. For example, there are standard data access (entity framework) and model-view-controller (MVC) frameworks built-in. Most developers use those standard frameworks. This makes it easy as a developer to move between teams and quickly understand how things work. Your knowledge and skills become more portable due to this.

.NET Core Is Open Source

One of the biggest changes to ever happen to .NET was the open sourcing of the code. Virtually all of the code is now on GitHub for anyone to review, fork, and contribute to. This is a huge change that most people in the industry never thought would happen.

As a developer, from time to time you need to look under the covers to see what your code is really doing. For example, in the past, I once wondered if I called Dispose() on a database connection if that closes the connection or not. If you can access the source code somehow, you can quickly verify these types of questions.

Even if you don’t contribute to the source code, you benefit from the huge community that is. Problems and improvements are quickly discussed, coded, and released for you to use on a regular basis. Gone are the days of waiting years in-between releases for major improvements or minor bug fixes.

What is business intelligence (BI)? Definition from #business #intelligence #database


business intelligence (BI)

Business intelligence (BI) is a technology-driven process for analyzing data and presenting actionable information to help corporate executives, business managers and other end users make more informed business decisions. BI encompasses a wide variety of tools, applications and methodologies that enable organizations to collect data from internal systems and external sources, prepare it for analysis, develop and run queries against the data, and create reports, dashboards and data visualizations to make the analytical results available to corporate decision makers as well as operational workers.

Hadoop 2 Upgrades: Ready to Take Advantage?

Hadoop doesn’t lack for attention, but that has yet to translate into high adoption or success rates. Find out if you should leverage Hadoop 2 upgrades here.

By submitting your personal information, you agree that TechTarget and its partners may contact you regarding relevant content, products and special offers.

You also agree that your personal information may be transferred and processed in the United States, and that you have read and agree to the Terms of Use and the Privacy Policy .

The potential benefits of business intelligence programs include accelerating and improving decision making; optimizing internal business processes; increasing operational efficiency; driving new revenues; and gaining competitive advantages over business rivals. BI systems can also help companies identify market trends and spot business problems that need to be addressed.

BI data can include historical information, as well as new data gathered from source systems as it is generated, enabling BI analysis to support both strategic and tactical decision-making processes. Initially, BI tools were primarily used by data analysts and other IT professionals who ran analyses and produced reports with query results for business users. Increasingly, however, business executives and workers are using BI software themselves, thanks partly to the development of self-service BI and data discovery tools.

Business intelligence combines a broad set of data analysis applications, including ad hoc analysis and querying, enterprise reporting, online analytical processing (OLAP ), mobile BI. real-time BI. operational BI. cloud and software as a service BI. open source BI. collaborative BI and location intelligence. BI technology also includes data visualization software for designing charts and other infographics. as well as tools for building BI dashboards and performance scorecards that display visualized data on business metrics and key performance indicators in an easy-to-grasp way. BI applications can be bought separately from different vendors or as part of a unified BI platform from a single vendor.

BI programs can also incorporate forms of advanced analytics. such as data mining. predictive analytics. text mining. statistical analysis and big data analytics. In many cases though, advanced analytics projects are conducted and managed by separate teams of data scientists. statisticians, predictive modelers and other skilled analytics professionals, while BI teams oversee more straightforward querying and analysis of business data.

Business intelligence data typically is stored in a data warehouse or smaller data marts that hold subsets of a company’s information. In addition, Hadoop systems are increasingly being used within BI architectures as repositories or landing pads for BI and analytics data, especially for unstructured data. log files, sensor data and other types of big data. Before it’s used in BI applications, raw data from different source systems must be integrated, consolidated and cleansed using data integration and data quality tools to ensure that users are analyzing accurate and consistent information.

In addition to BI managers, business intelligence teams generally include a mix of BI architects, BI developers, business analysts and data management professionals; business users often are also included to represent the business side and make sure its needs are met in the BI development process. To help with that, a growing number of organizations are replacing traditional waterfall development with Agile BI and data warehousing approaches that use Agile software development techniques to break up BI projects into small chunks and deliver new functionality to end users on an incremental and iterative basis. Doing so can enable companies to put BI features into use more quickly and to refine or modify development plans as business needs change or new requirements emerge and take priority over earlier ones.

Sporadic usage of the term business intelligence dates back to at least the 1860s, but consultant Howard Dresner is credited with first proposing it in 1989 as an umbrella category for applying data analysis techniques to support business decision-making processes. What came to be known as BI technologies evolved from earlier, often mainframe-based analytical systems, such as decision support systems and executive information systems. Business intelligence is sometimes used interchangeably with business analytics ; in other cases, business analytics is used either more narrowly to refer to advanced data analytics or more broadly to include both BI and advanced analytics.

T-SQL Programming Part 5 – Using the CASE Function #microsoft, #articles, #microsoft


T-SQL Programming Part 5 – Using the CASE Function

Have you ever wanted to replace a column value with a different value based on the original column value? Learn how, with the T-SQL CASE function.

The CASE function is a very useful T-SQL function. With this function you can replace a column value with a different value based on the original column value. An example of where this function might come in handy is where you have a table that contains a column named SexCode, where 0 stands for female, 1 for male, etc. and you want to return the value “female” when the column value is 0, or “male” when the column value is 1, etc. This article will discuss using the CASE function in a T-SQL SELECT statement.

The CASE function allows you to evaluate a column value on a row against multiple criteria, where each criterion might return a different value. The first criterion that evaluates to true will be the value returned by the CASE function. Microsoft SQL Server Books Online documents two different formats for the CASE function. The “Simple Format” looks like this:

And the “Searched Format” looks like this:

Where the “input_expression” is any valid Microsoft SQL Server expression, the “when_expression” is the value in which the input_expression is compared, the “result_expression ” is the value that will be return for the CASE statement if the “when_expression” evaluates to true, ” . n ” represents that multiple WHEN conditions can exist, the “else_result_expression ” is the value that will be returned if no “when_expression” evaluates to true and in the “Searched Format” the “Boolean_expression” is any Boolean express that when it evaluates to true will return the “result_expression”. Let me go through a couple of examples of each format to help you better understand how to use the CASE function in a SELECT statement.

For the first example let me show you how you would use the CASE function to display a description, instead of a column value that contains a code. I am going to use my earlier example that I described at the top of this article where I discussed displaying “female” or “male” instead of the SexCode. Here is my example T-SQL Code:

Here is the output from this T-SQL code:

This example shows the syntax in action for a CASE function using the “Simple Format”. As you can see the CASE function evaluates the PatientSexCode to determine if it is a 0, 1, or 2. If it is a 0, then “female” is displayed in the output for the “Patient Sex” column. If the PatientSexCode is 1, then “male” is display, or if PatientSexCode is 2 then “unknown” is displayed. Now if the PatientSexCode is anything other than a 0, 1 or 2 then the “ELSE” condition of the CASE function will be used and “Invalid PatientSexCode” will be displayed for the “Patient Sex” column.

Now the same logic could be written using a “Searched Format” for the CASE function. Here is what the SELECT statement would look like for the “Searched Format”:

Note the slight differences between the “Simple” and “Searched” formats. In the “Simple” format I specified the column name for which row values will be compared against the “when_expressions” ,where as in the “Searched” format each WHEN condition contains a Boolean expression that compares the PatientSexCode column against a code value.

Now the CASE function can be considerably more complex than the basic examples I have shown. Suppose you want to display a value that is based on two different columns values in a row. Here is an example that determines if a Product in the Northwind database is of type Tins or Bottles, and is not a discontinued item.

The output for the above command on my server displays the following:

As you can see I’m using a “Searched Format” for this CASE function call. Also, each WHEN clause contains two different conditions. One condition to determine the type (tins, or bottles) and another condition to determine if the product has been discontinued. If the QuantityPerUnit contains the string “Tins” and the Discontinue column value is 0 then the “Type of Availability” is set to “Tins”. If the QuantityPerUnit contains the string “Bottles” and the Discontinue column value is 0 then the “Type of Availability” is set to “Bottles”. For all other conditions, the “Type or Availability” is set to “Not Tins , Not Bottles , or is Discontinued.

The WHEN clauses in the CASE function are evaluated in order. The first WHEN clause that evaluates to “True” determines the value that is returned from the CASE function. Basically, multiple WHEN clauses evaluate to “True”, only the THEN value for the first WHEN clause that evaluates to “True” is used as the return value for the CASE function. Here is an example where multiple WHEN clauses are “True.”

The output on my machine for this query looks like this:

If you look at the raw titles table data in the pubs database for the title “You Can Combat Computer Stress!” you will note that the price for this book is $2.99. This price makes both the “price 12.00” and “price 3.00” conditions “True”. Since the conditions are evaluated one at a time, and the “price 12.00” is evaluated prior to the “price 3.00,” the “Price Category” for the title “You Can Combat Computer Stress!” is set to “Cheap”.

The CASE function can appear in different places within the SELECT statement, it does not have to only be in the selection list within the SELECT statement. Here is an example where the CASE function is used in the WHERE clause.

The output for this query looks like this:

Here I only wanted to display books from the titles table in pubs database if the price category is ‘Average’. By placing my CASE function in the WHERE clause I was able to accomplish this.


As you can see the CASE function is an extremely valuable function. It allows you to take a data column and represent it differently depending on one or more conditions identified in the CASE function call. I hope that the next time you need to display or use different values for specific column data you will review the CASE function to see if it might meet your needs.

Steps to Rebuild Master Database In SQL Server #backup #database #sql #server


Rebuild Master Database in SQL Server Without Backup

It has been observed that many SQL Server administrators, in fact majority of them, backup their user databases regularly, but turn a blind eye to the system databases. While most of them do not understand the value of these databases, some remain in their comfort zone owing to the years of no failure. Whatever be the reason, we will help you to be acquainted with the methods to restore the system databases, should the admins find themselves in a crucial situation.

Reasons Behind Master Database Rebuilding

There are a number of reasons due to which, the master database needs to be rebuild. Some of them are:

  • At times, user delete some crucial information like linked servers, logins, SQL Server configuration, and other user objects.
  • The master database is not coming online and the admin does not have a backup of the master database.
  • It can also happen that the master database has been corrupted due to various hardware and software failure and can no longer be used.
  • The administrator might want to make a clone of the server or might want to restore the master database to a new instance.

How to Rebuild Master Database in SQL Server?

The following procedure will help you to rebuild the master system database. The entire process, which we will discuss in this write up, will be divided into three sections for the convenience of the users.

1. Pre-Rebuild Process

Since, only the master database is corrupt, therefore, in order to ensure the authenticity of other system database files, it gets necessary to take their backup. The files that need to be backed up are MSDB Data, MSDB Log, model model Log In order to do so, follow the below mentioned steps:

  • Open SQL Server Configuration Manager.
  • From the left pane, select SQL Server Services option. This will list all the services that are currently running.
  • Right click on the service and select Stop option for stopping all the services one by one.
  • Exit SQL Server Configuration Manager.
  • Browse to the location where all the system files of a particular SQL Server instance are stored.

C:\Program Files\Microsoft SQL Server\[INSTANCE NAME]\MSSQL\DATA

Note: Keep in mind this location, as this is where the master database files will be rebuild automatically.

  • Cut all the healthy system files, save them in a new folder, and delete corrupted master mastlog, tempdb, templog files.

2. Rebuilding Process

The steps that are followed for rebuilding are:

  • In the command prompt, change the directory location of the server instance to the location where the SQL Server 2016 installation media.
  • Open Command Prompt as Administrator.
  • Since my installation media is stored in the F: Drive, change the directory location by entering f: and press Enter.
  • The next step is to run the following command:

    Note: In case your account name contains a blank space, keep in mind to enclose the account name within quotes. Moreover, if you are specifying multiple accounts, separate them with a space.
  • When all the system databases are rebuilt, it returns no message in the command prompt. In order to verify whether the process has been completed successfully, examine the summary.txt file. the location of this file is:
    C:\Program Files\Microsoft SQL Server\130\Setup Bootstrap\Logs

3. Post-Rebuild Process

  • The first step after rebuilding is to restart all the services, which were stopped earlier.
  • If you have backups of model and MSDB databases, restore them.
  • In case the backup is not present, simply replace the rebuilt MSDB and model files with the files that were backed up in the I. section. (This should be done after stopping the services).

In this blog, we have described the full procedure for rebuilding the master database in the scenario when the backup is not available.We believe that with its help you will be able to rebuild the master database successfully.

5 SQL Server 2014 Security Enhancements #sql #server #2014, #database #security


5 SQL Server 2014 Security Enhancements

SQL Server 2014 continues the Microsoft commitment to excellence in security. According to the National Institute of Standards and Technology (NIST) public security board, SQL Server reportedly has the lowest number of security vulnerabilities across major database vendors. In addition, SQL Server has been deemed the most secure database by the Information Technology Intelligence Consulting (see, SQL Server Delivers Industry-Leading Security , 2010 and Stratus ftServer and SQL Server Deliver Continuous Availability , 2012).

SQL Server 2014 offers Common Criteria (CC) Certification at the High Assurance Level, as well as enhanced separation of duty for greater security. Additional new features include Transparent Data Encryption for better data protection and Encryption Key Management, allowing the storage of keys on a separate server.

1. Transparent Data Encryption (TDE)

In SQL Server 2014, TDE functionality takes the non-encrypted backup data and encrypts the data before writing it to disk. In order to preserve a major compression factor of SQL Server backup compression in conjunction with the newly introduced encryption, the compression is performed on the backup data first, before the encryption is applied to the compressed data. With this order of actions, a major compression factor can be preserved while the backup as it rests on the backup vehicle is encrypted.

2. Encryption Key Management

As discussed above, to secure your backup data in SQL Server 2014, you can now select to encrypt when you create a backup. The encryption options include an encryption algorithm and a certificate or asymmetric key to be used for the encryption. Only asymmetric keys residing in the Extended Key Management is supported.

Multiple encryption algorithms up to AES 256-bit are supported giving you a variety of algorithms to choose from. Adding backup encryption to a TDE encrypted database, gives additional protection for your data.

You can control the process using PowerShell. SQL Server Management Objects (SMO), or SQL Server Management Studio (SSMS), or T-SQL. Encryption options can also be used when configuring SQL Server Managed Backup to Windows Azure, therefore providing additional security for your off-site data.

It is very important that the certificate or key used for encrypting must be backed up to a different location than the backup that the certificate or key is used to encrypt. Without this certificate or key the backup file cannot be restored. For more information, see: Backup and Restore Enhancements in SQL Server 2014 CTP2 .

New Server-Level Permissions

SQL Server 2014 also has 3 new server-level permissions.


Grant CONNECT ANY DATABASE to a login that must connect to all databases that currently exist and to any new databases that might be created in future. This permission does not grant any permission in any database beyond connect. You may combine CONNECT ANY DATABASE permission with SELECT ALL USER SECURABLES or VIEW SERVER STATE to allow an auditing process to view all data or all database states on the instance of SQL Server.


When granted, IMPERSONATE ANY LOGIN allows a middle-tier process to impersonate the account of clients connecting to it, as it connects to databases. When denied, a high privileged login can be blocked from impersonating other logins. For example, a login with CONTROL SERVER permission can be blocked from impersonating other logins.


When SELECT ALL USER SECURABLES permission is granted, a login such as an auditor can view data in all databases that the user can connect to. For additional information, see What s New (Database Engine)

Quickbooks over VPN? Archive – Micro Focus Forums #operations, #work, #quickbooks, #long,


05-Apr-2005, 07:16 PM

I recently set up our new accountant with the BM vpn and NW clients so that
she might be able to access our quickbooks 2000 database via a mapped drive
while connected to our BM3.7 server. She can connect fine, and althought QB
(a known resource hog) is fairly slow for most common operations over the
vpn (both client and server have SDSL connections over 500kbps), it is not
entirely unworkable. SOME particular operations, however, take an
IMPOSSIBLY long time (especially find operations in the records DB),
literally many, many orders of magnitude slower than everything else.

Is this really just due to the number of drive accesses involved in these
operations, or is there some other buggy issue at work here?

Does anyone know how to troubleshoot/work around this problem effectively?
We are really trying to avoid having to shutdown/lock the QB system long
enough for our accountant to copy the DB to a local machine, do her work,
and then write it back out to our system. We really need a way for her to
be able to work remotely AND concurrently with the rest of us.

Many, many thanks in advance for any help.

You will probably need to take some traces (Ethereal on the PC’s
involved) to see what kind of traffic is involved. Might be as simple
as needing to reduce MTU size on one or both ends of that connection.

Perhaps simpler would be to use pcANYWHERE, VNC or terminal server/RDP
to remote control an internal PC over the VPN to do the work remotely.

My experience with Quickbooks over a lan is that the newer versions can be a
little slow as it is. I would venture to say that there is just way too
much data to push through that small DSL pipe.

14-Apr-2005, 04:07 PM

Thanks for the input Craig and JP,

I apologize for my own sluggish response. I actually found a post on
another site that echoed Craig’s suggestion of running quickbooks on a local
machine and having the remote client connect to it using pcAnywhere or the
like so that all the heavy drive accesses remain local. I’m going to give
that a try.

Thanks again for the help,

Cool Things to Do with Netsh #netsh, #microsoft #windows #server #2003, #windows


Cool Things to Do with Netsh

The Netsh command is a powerful command-line tool for Windows Server 2003, Windows XP, and Windows 2000. Netsh is available in the Microsoft Windows 2000 Server Resource Kit and is standard in Windows 2003 and XP. Netsh lets you change almost any network configuration setting as well as document network configurations. You can use the command in a batch file or from its own command shell. Netsh has a useful Help system that you can access by adding /? to almost any of its subcommands. Here are 10 cool things that you can use Netsh to do.

10. Show TCP/IP settings The command

shows the system s current TCP/IP configuration settings. You can see whether the system is using DHCP or static addressing as well as view the system s current IP address, subnet mask, gateway address, and DNS servers.

9. Change network configuration Netsh can change the current network configuration. The command

sets the IP address of the system configuration Local Area Connection to, the subnet mask to, and the gateway address to This use of Netsh comes in handy for laptops that must switch between static and dynamic addressed networks.

8. Use a dynamic DHCP assigned address The command

sets the IP address of the Local Area Connection system configuration to use DHCP addressing.

7. Change a DNS server address When you change the system s IP address type, you almost always have to change the DNS server s address as well. The command

configures the Local Area Connection to use a DNS server whose address is

6. Dynamically assign the DNS server address When you switch to dynamic DHCP addressing, you typically also want the DNS server address to be assigned dynamically. The command

sets the Local Area Connection interface to use a DHCP-assigned DNS address.

5. Configure a WINS server Netsh also lets you configure WINS servers. The following command configures a system s Local Area Connection interface to use a WINS server that has the IP address

4. Work with other interfaces Netsh works with DHCP, Internet Authentication Service (IAS), and RAS interfaces as well as the local network interface. The command

dumps the local DHCP server s configuration to the dhcpcfg.dat file. You can use this file in conjunction with Netsh to recreate the DHCP server.

3. Work with remote systems One of Netsh s best hidden features is its ability to work with remote systems. The command

sets the current computer to a different system on the network.

2. Save the current configuration The Interface Dump subcommand saves your current network configuration and generates a script that you can use to regenerate the configuration. The command

redirects the Dump command to the mycfg.dat file.

1. Restore network configuration The Netsh Exec command runs a Netsh script file. The command

restores to your system the network configuration data that the preceding sample command saved.

I too ran into this problem. Do this: 1. Create a batch file called netsh.bat ( for example ) with the netsh commands you would like to run ( just as they would run locally on your PC ) 2. Copy netsh.bat to C:\ (for example) on all of the nodes that need the change ( you can copy netsh.bat across your LAN via another batch file ). 3. With another batch file, schedule an AT job on each node that needs the change: this at job should run c:\netsh.bat ( that has already been copied to each node that needs the change ). This works becuase the job is running locally on each PC, rather than being pushed from another. Thanks, and good luck. -LP

To add multiple DNS entries you need to type: netsh interface ip set dns name=”Wireless Network Connection” source=static addr= register=PRIMARY netsh interface ip add dns name=”Wireless Network Connection” addr= index=2 They need to be entered on a separate line.

Cameron Fairbairn (not verified)

In order to add multiple DNS servers, use the following syntax: add dns “Local Area Connection” add dns “Local Area Connection” index=2 index=2 adds the IP as a secondary dns server.

Wow, that came out ugly, let me try again: C:\WINNT\system32>netsh netsh>interface interface>show interface Admin State State Type Interface Name ————————————————————————- Enabled Dedicated Local Area Connection Enabled Internal Internal Enabled Loopback Loopback (Note: Look for “Dedicated” connection types with any name other than a GUID) interface>ip interface ip>delete dns “Local Area Connection” all interface ip>set dns “Local Area Connection” static interface ip>add dns “Local Area Connection” index=2

Would anyone know why I am getting the following error with #3, which is the remote command. When I run “netsh set machine virtual2000” I get the following response “WARNING: Could not obtain host information from machine: []. Some commands may not be available. Access is denied” The result is identical when I try “netsh -r virtual2000” I have tried physical servers as well, but I get the same result. I tried to google the error, but I don’t see anything. The netsh interface works fine until you get to the “set IP address” portion”. At that point, the available commands are blank.

Netsh is available in the Microsoft Windows 2000 Server Resource Kit and is standard in Windows 2003 and XP.” should be changed to “The Netsh command is a powerful command-line tool that is installed by default for Windows Server 2003, Windows XP, and Windows 2000.” Netsh is included with Windows 2000, not as part of the Windows 2000 Server Resource Kit. Thanks.

Amazon Virtual Private Cloud (VPCs) and Amazon RDS – Amazon Relational Database


Amazon Virtual Private Cloud (VPCs) and Amazon RDS

There are two Amazon Elastic Compute Cloud (EC2) platforms that host Amazon RDS DB instances, EC2-VPC and EC2-Classic. Amazon Virtual Private Cloud (Amazon VPC) lets you launch AWS resources, such as Amazon Relational Database Service (Amazon RDS) DB instances, into a virtual private cloud (VPC).

When you use an Amazon VPC, you have control over your virtual networking environment: you can select your own IP address range, create subnets, and configure routing and access control lists. The basic functionality of Amazon RDS is the same whether your DB instance is running in an Amazon VPC or not: Amazon RDS manages backups, software patching, automatic failure detection, and recovery. There is no additional cost to run your DB instance in Amazon VPC.

Accounts that support only the EC2-VPC platform have a default VPC. All new DB instances are created in the default VPC unless you specify otherwise. If you are a new Amazon RDS customer, if you have never created a DB instance before, or if you are creating a DB instance in a region you have not used before, you are most likely on the EC2-VPC platform and have a default VPC.

Some legacy DB instances on the EC2-Classic platform are not in a VPC. The legacy EC2-Classic platform does not have a default VPC, but as is true for either platform, you can create your own VPC and specify that a DB instance be located in that VPC.

This documentation only discusses VPC functionality relevant to Amazon RDS DB instances. For more information about Amazon VPC, see Amazon VPC Getting Started Guide and Amazon VPC User Guide.

    Understanding SQL Server Backup Types #backup #database #sql #server


    Understanding SQL Server Backup Types

    Applies to: SQL Server 2000, SQL Server 2005

    Database backups are at the core of any SQL Server disaster recovery planning for any production system. Backups may be used to provide a means of recovery to a point-in-time when the database was last operational. Microsoft® SQL Server™ provides several types of backups that may be combined to formulate a customized disaster recovery plan depending on the nature of the data and the recovery requirements. It is highly recommended that all SQL Server databases be backed up periodically.

    SQL Server backup media

    A database may be backed up to disk or to tape. The examples in this article assume a disk backup directly into a disk file (as opposed to a disk backup device). Any database can be backed up to a random disk file at any time. The file may either be initialized (using WITH INIT) or appended with the new backup.

    Types of backups in SQL Server

    SQL Server provides several different kinds of backups including Complete. Differential. Transaction Log. andFile(s) and Filegroup(s) backup. A combination of these backups may be used to formulate a robust disaster recovery strategy. The following paragraphs explain each SQL Server backup type

    Complete database backup

    A complete database backup creates a stand-alone image of the entire database. A complete database backup is self-dependent and may be restored to either the same or a new database on the same or a different server. This provides plenty of flexibility at the time when this backup has to be restored. A complete backup may be restored without the need for any other kind of backup. It may also be performed for databases in any recovery model. Restoring a complete database backup typically would be considered a starting point for a disaster recovery situation where the entire database is lost or damaged. It is recommended that a complete database backup be performed at regular intervals for all production databases. It is also recommended that a complete backup should be performed for system databases if there are any changes performed to the SQL Server operating environment such as creating or removing databases, configuring security, creating and modifying DTS/SSIS packages or scheduled jobs, adding and removing linked servers, etc.

    Differential database backup

    A differential backup backs up only modified extents since the last complete backup. An extent is a group of 8 data pages each consisting of 8 KB (64 KB in total). By definition, differential backups are cumulative. The most recent differential backup contains all changes from all previous differential backups performed since the most recent complete database backup. Differential backups may be considered as an alternative for databases that are large and are modified infrequently. These would include data warehouse type of databases. Differential backups have several limitations including the following:

    • They do not provide point-in-time restore capabilities
    • They may only be restored after a complete database backup is restored
    • They may not be performed on the master database

    Transaction log backup

    An SQL Server database consists of two components: data file(s) and transaction log file(s). A transaction log captures the modifications made to the database. A simple transaction may place several records in the transaction log. Each of these records is known as a log record and is assigned a unique identification number known as the log sequence number (LSN). Log records that belong to the same transaction are linked together through the LSN. If SQL Server service shuts down unexpectedly, upon restart the recovery process examines the entries in the transaction log and if there are transactions that have not been rolled forward completely, the recovery process rolls back the changes performed as part of these incomplete transactions. This operation is extremely important as it forms the basis of transactional recovery. Entries in the transaction log are also used if transactional replication is configured for the specific database.

    A transaction log backup backs up all transactions since either the previous transaction log backup, or the complete database backup if there have been no transaction log backups performed for the database in the past. This backup may then be used to apply the backed-up changes, in case disaster recovery is required. Transaction log backups may only be applied to a database in an unrecovered state. A database may be in an unrecovered state if it is being restored from a set of backups as part of a disaster recovery procedure, or if it is configured as a standby database on a warm backup server. A transaction log backup also truncates the inactive portion of the transaction log, unless the database is configured as a Publisher in transactional replication and there are transactions pending propagation to Subscribers.

    Each transaction log backup contains a First and Last log sequence number (LSN). Consecutive transaction log backups should have sequential LSNs for the boundary log records. These LSN values may be examined using the RESTORE HEADERONLY command. If LastLSN from the previously restored transaction log backup does not match the FirstLSN from the backup that is currently being restored, the restore operation fails with the following error: This backup set cannot be restored because the database has not been rolled forward far enough. You must first restore all earlier logs before restoring this log . If the above message is generated while restoring a particular transaction log backup, which is part of a set of transaction log backups that are to be restored, any attempts to restore further transaction log backups will fail with this message. There could be several reasons for consecutive transaction log backups being out of sequence. Some of the most common reasons noted from support experience have been:

    • The database recovery model has been changed to Simple and back to either Full or Bulk-Logged. Switching the recovery mode to Simple causes the transaction log to be truncated
    • Another transaction log backup was performed between the previous successfully restored backup and the one generating this message
    • The transaction log was manually truncated between the two backups
    • The database was in Bulk-Logged recovery model and non-logged operations were performed
    • Transaction log backups are not allowed for databases in Simple Recovery model. While in Simple Recovery model, a database’s transaction log is truncated every time a CHECKPOINT is invoked for the database

    Transaction log backups provide the possibility of performing a point-in-time restore or point-of-failure restore. You can also perform a restore to a named transaction with transaction log backups.

    File(s) and Filegroup(s) backup

    Use BACKUP to back up database files and filegroups instead of the full database when time constraints make a full database backup impractical. To back up a file instead of the full database, put procedures in place to ensure that all files in the database are backed up regularly. Also, separate transaction log backups must be performed. After restoring a file backup, apply the transaction log to roll the file contents forward to make it consistent with the rest of the database.
