MS SQL Server Backups & Restore: Steps explained

Image
Yes I know, there are lots of articles and posts about this topic. But I want to show, what are things to be known to recover the database to specific point-in-time. Backup As you know there are 3 recovery models supported in MS SQL server.
Simple Automatically clear the log file. Only allows  recover to end of a backup. No log backupsFull Requires log backups No work is lost, if data (.mdf) file get damaged/lost Can recover to a specific point-in-time.Bulk-logged Requires log backups Use minimal logging for bulk operations, thereby reducing the log space Point-in-time recovery is not supported. In a mission critical environment, Full recovery model is the most recommended. In this post I’m paying attention to this model and simply explain point-in-time recovery. From your SQL server database you can take, 3 back up types.

DUMP TRAN <Dbname> WITH TRUNCATE_ONLY & MSSQL 2008

To Shrink the database log file I’ve used to,
1: 2:DUMPTRAN <DatabaseName> WITH TRUNCATE_ONLY 3:GO 4: 5:USE <DatabaseName> 6:DBCC SHRINKFILE (<DatabaseName>_log, 100); 7:GO 8:

This is not work in SQL 2008, as DUMP is discontinued. Otherwise we have to use BACKUP.

To shrink the log file in SQL 2008,
Back up the database in “SIMPLE” recovery mode. then run above line no 6.
Refer this (http://msdn.microsoft.com/en-us/library/ms144262.aspx) for discontinued functionalities in SQL 2008.

BackgroundWindows XP users are keep complaining me about  crashes of WPF application as soon I released it.  I was wandered, why all Windows 7 users don’t have that. My team mate did couple of enhancements plus adding new application’s window icon. The error message they receive is (crashing message !),ProblemSince everything working perfectly on Windows 7, something wrong with XP to what we did lastly. That is replacing the icon. But I have no proof for that, but  got a clue from the following screen.Hm…., I change the icon to a very classic one and try it. WOW, it is working fine in XP. Now I want to find out what is the different between this icon and the my icon. I found that my icon containing additional two image types (256x256, 32bit,PNG), which you can be seen from the Visual Studio Icon editor.SolutionI removed these two image types from the icon file using Visual Studio Icon Editor, added to the application and  it’s work fine.To justify the situation, I found this (accessed…

During last week, I have attended to WS02 conference. The company, WS02, known as SOA company but I would like to call them Platform Enabler. They have done really good work in open source.

If I’m not wrong, WSO2 started somewhere around 2005-2006, but they made a good journey so far. Best of luck for your future.

BizTalk 2010 EDI : Parties/Party Migration

Image
Parities cannot be directly migrated from order version to BizTalk 2010. Because,  Trading Partner Management (TPM) has been re-engineered in BizTalk 2010. You have to use BizTalk Server Party Migration Tool. Party Creation in 2010 is more logical & practical than 2006 R2. New changes are:We have to create a party (Trading Partner) along with a business profile. Business Profile is analogue to the business divisions in an organization where can have multiple. Each business profiles define parameters for B2B messaging like identifiers, Encoding formats, Protocol  settings.

Figure 1In order to do B2B messaging, we have to define agreement(s) between trading partners. This is very easy to use and understand.

As of Figure 2, once you select the second party (number 3 in the picture)  two more tabs on the dialog (number 6) where you defines the interchange and transaction set settings based on the protocol selected. 

If you have created protocol settings when creating party, y…

Visual Studio 2010: Displaying Assembly in “Add Reference” Dialog Box

Connecting DB2/iSeries From .net Application

Image
I need to connect to a DB2 from a .net application. But it’s  in iSeries system. I did not know what is the way do it. I read lot of articles/blog posts and really helped me. But in this post, I thought to consolidate them for fast reference. There are two .net data providers for DB2.IBM.Data.DB2.iSeries IBM.Data.DB2Both provider follows same rules/guidelines of common ADO.net components. For an example, both have Connection, Command, DataAdapter, DataReader. But there are differences and limitations.IBM.Data.DB2.iSeriesUsing this provider you can only access to iSeries system. You have to install iSeries Client Access to development machine and/or server. It is quite a bit setup file ( > 3GB with 64Bit version), but we required (refer the bellow screen shots).NET Data Provider Header,Library and Documentation. Figure 1There are limitations/unsupported features [IBM Redbooks 2005 ,Page 38]  in this provider, bellow lists 3 out of 11. User-defined types (UDTs): Although some featu…

Image
For my developments, I am using VS 2005, VS 2008 and VS 2010 side  by side. I have developed couple of Add-ins (XML Add-Ins) for my own use to ease the development, one can be found in this blog.Last week I installed DB2 connection tool kit( for testing purposes) which installed a VS Add-in (COM Add-in) too. I removed that product from my system, it also removing the Add-ins. My other Add-ins also gone from the “Tool” menu (This happened only to VS 2005 & 2008). But in Add-In Manger I can see them,What I did?I found lots of tips from the Net. All are talking about Registry Entries and devenv command.running devenv /setup


failed.

Changing
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\<version>\PreloadAddinStateManaged
<MyAddIn Name> value

value 2 to 1 failed.
running
devenv.exe /resetaddin [Namespace].Class
worked. This wont delete any Add-ins from the disk. You have to re-load them from the Add-ins Manger.
