SQL Server # Moving MASTER database in cluster environment

Few months back I have wrote post about moving MASTER and MSDB database to new location in stand alone machine.

In recent past we had a situation where customer asked us to move MASTER database to new location, below are the steps I have taken:

  1.     Connect to the Server
  2.     Open Configuration Manager -> SQL Server Service
  3.     Right Click and say Properties
  4.     Click on the Start-up Parameter
  5.     Remove start-up parameter (the highlighted one)
	 -dOLDLocation\master.mdf
-eOLDLocation\ErrorLog
-lOLDLocation\mastlog.ldf



 



      6.     Add new start-up parameters with new values (per your configuration)

   




	 -dNewLocation\master.mdf
-eNewLocation\ErrorLog
-lNewLocation\mastlog.ldf



      7.    Check and confirm which node is active

      8.    PAUSE current PASSIVE Node  to avoid fail-over


      9.    Take SQL Server resources offline, i.e. SQL Server, SQL Agent, MSDTC, SQLCLUSTER Name (do not take SQL Cluster IP Offline)


    10.    Copy MASTER.MDF and MASTLOG.LDF to NEW Location ( S:\SQLDATA, yours could be different)


    11.    Log into Cluster Administrator and bring SQL Server Resources online


    12.    Resume current PASSIVE Node



 



That's all, you should be able to see your master database on new location now!!!

SQL Server # TSQL to Convert STRING in PROPER format

Problem Statement

SQL Server has got in-built functions to convert the given string into LOWER() or UPPER() format but it does not provides any direct way to convert it to PROPER format. A string/text is said to be in a PROPER format if all the words in that string/text starts with a CAPITAL letter.

E.g. If a string is - “Hello, how are you?”,

String in Lower format = “hello, how are you?”

String in Upper format = “HELLO, HOW ARE YOU?”

and String in Proper format = “Hello, How Are You?”

 

Implementation

Ideally, SQL Server is not the right place to implement this kind of logic, as string operations are costlier in SQL from performance perspective. it should be either implemented in the Front-End language or the Reporting Tool as this more related to the formatting. However, if this is to be implemented in SQL, the more preferred way is to use SQL-CLR function. It does not mean that we can not achieve this with T-SQL.

Today, I will share a simple T-SQL function, which could be used to convert any given string in PROPER format. Below is the script -

CREATE FUNCTION [dbo].[PROPER]



(



  @StrToConvertToProper AS VARCHAR(MAX)



) 



RETURNS VARCHAR(MAX) 



AS



BEGIN



  --Trim the Text



  SET @StrToConvertToProper = LTRIM(RTRIM(@StrToConvertToProper))



 



  --Find the No. of Words in the Text



  DECLARE @WordCount AS INT



  SET @WordCount = LEN(@StrToConvertToProper) - LEN(REPLACE(@StrToConvertToProper,' ','')) + 1



 



  --Variable to track the space position



  DECLARE @LastSpacePosition AS INT = 0



 



  --Loop through all the words



  WHILE(@WordCount > 0)



    BEGIN



      --Set the Space Position



      SET @LastSpacePosition = CHARINDEX(' ',@StrToConvertToProper,@LastSpacePosition + 1)



      



      --Replace the Character



      SET @StrToConvertToProper = STUFF(@StrToConvertToProper,



                                        @LastSpacePosition + 1,



                                        1,



                                        UPPER(SUBSTRING(@StrToConvertToProper, @LastSpacePosition + 1, 1)))



      --Decrement the Loop counter                                      



      SET @WordCount = @WordCount - 1



    END



    



  RETURN @StrToConvertToProper



END  




When the above script is used as –





SELECT dbo.PROPER('hello, how are you?')






we get the following result - Hello, How Are You?



Conclusion



The given script could be used to convert any string in PROPER format using T-SQL. However, I would personally prefer converting the string at the Front-End or in the Reporting tool to display the string in this format.

Moving MASTER Database

In my previous post we see how to move MSDB database, today we will see how to move or relocate MASTER database. While moving MASTER database we’ll have to consider few other things like changing start-up parameter for SQL Server Service. I will also mention those stops here for better understanding. Let’s do it step-by-step.

Step 1: Query sys view and note down the existing location for MASTER database

USE MASTER 
GO 
SELECT 
NAME, 
PHYSICAL_NAME AS 'PhysicalFilePath', 
STATE_DESC AS 'DB Status' 
FROM SYS.MASTER_FILES 
WHERE NAME LIKE 'Mast%'

Screen001

Step 2: Run alter database command and change the location for database files

ALTER DATABASE MASTER 
MODIFY FILE 
( 
NAME = MASTER, 
FILENAME= 'C:\SQLDB\Demo\Master.mdf' 
) 
GO 
ALTER DATABASE MASTER 
MODIFY FILE 
( 
NAME = MastLog, 
FILENAME= 'C:\SQLDB\Demo\MastLog.mdf' 
) 
GO 

Screen002

Step 3: Stop SQL Server Service and move database files to new location

Step 4: Restart SQL Server Service, surprised ?

Screen003 

Step 5: This was expected, let’s see what errorlog has to say about this!

Screen004

Refer the highlighted section, SQL Server service could not find the files. This is because we have moved that files to new location.

Step 6: Okay, so let’s go and change the start-up parameter. We can do this using Configuration manager.

Step 7: Right click on SQL Server service –> Properties –> Start-up Parameter

Screen005

Step 8: Make correction in path for Master.mdf and Master.ldf

Step 9: Start SQL Server service, this time it will start.

You are done!!

Note: This is to be done when we have to do relocate databases to new drive, or file organization, or some error which force us to do this.

Moving MSDB to new location

In recent past we have a situation where in we required to move MSDB, Model and Master databases to new location, the reason being faulty drive. While moving system databases to new location we need to be extra cautious. Let’s see the process step-by-step.
Step 1: Let’s query sys view and note down the location for database files

SELECT
NAME,
PHYSICAL_NAME AS 'PhysicalFilePath',
STATE_DESC AS 'DB Status'
FROM SYS.MASTER_FILES
Screen001
Step 2: Run alter database and specify new location for database
SELECT
ALTER DATABASE MSDB
MODIFY FILE
(
NAME = MSDBData,
FILENAME= 'C:\SQLDB\Demo\MSDBData.mdf'
)
GO
ALTER DATABASE MSDB
MODIFY FILE
(
NAME = MSDBLog,
FILENAME= 'C:\SQLDB\Demo\MSDBLog.ldf'
)
GO
Screen002
Step 3: Stop SQL Server service
Screen003
Step 4: Once SQL Server service is stopped move MSDB database to new location
Step 5: Now, start SQL Server service. This time it will use the new path that we have configured in Step 2.
Note: If you have enabled and configure Database Mail, please make sure it works after you moved MSDB to new location.

Tomorrow, I will post about how to relocate Master database.

Troubleshooting Oracle Link Server Issue

Most of the time, due to different business requirements we do have to work on various RDBMS systems, Oracle and MS SQL Server are the widely used and popular RDBMS. Sometimes we need to import/export data from/to SQL Server and for that we’ve to use Link Server feature of MS SQL Server.

In one of my recent project, a critical application has a job that pulls in the data from an Oracle database, we have a DTS Package and some job scheduled for this task. since couple of days we’ve observed below error message in the job history and while running ad-hoc queries. I am penning down the error message and the solution (rather, temporary workaround) we have found out :

1) The operation could not be performed because the OLE DB provider 'MSDAORA' was unable to begin a distributed transaction.

==> In this case, rebooting MS DTS service  helped us.

2) The maximum number of active transactions that the MS DTC log file can accommodate has been exceeded.  You must increase the size of the MS DTC log file if you wish to initiate more concurrent transactions.

==> In this case, increasing Log file size helped us.

MSDTS_Log

3)Server: Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "MSDAORA" for linked server "OraLnkSvr" reported an error. The provider ran out of memory.

4) Server: Msg 7330, Level 16, State 1, Line 1
Cannot fetch a row from OLE DB provider "MSDAORA" for linked server "OraLnkSvr".
OLE DB provider "MSDAORA" for linked server "OraLnkSvr" returned message "Out of memory.".

==> In case 3 & 4, rebooting SQL Server service helped us.

 

Hope this helps.
