SQL 2005: Performance Counters are missing after installation

After installation of SQL Server 2005; Observed that SQL Server performance counters missing.

Below Query returns Zero rows.

select * from sys.dm_os_performance_counters
or
select * from sysperfinfo

Solution:
http://technet.microsoft.com/en-us/library/ms187743.aspx

Look at the setup log and search for error 3409, "Reinstall sqlctr.ini for this instance, and ensure that the instance login account has correct registry permissions" This denotes that performance counters were not enabled. The errors immediately prior to the 3409 listing should indicate the root cause for the failure of performance counter enabling.

Error when executing sp_helpdb

Error below would occur:
Server: Msg 515, Level 16, State 2, Procedure sp_helpdb,
Line 53
Cannot insert the value NULL into column 'owner',
table 'tempdb.dbo.#spdbdesc_____________________________ ___
__________________________________________________ _________
________________000100048505'; column does not allow
nulls. INSERT fails.

Solution:

1) Run Query below, to find the databases which has incorrect owner.

SELECT name, SUSER_SNAME(sid)
FROM master.dbo.sysdatabases
WHERE SUSER_SNAME(sid) IS NULL

2) Execute
sp_changedbowner 'sa'

How to find is Operating System is 32 Bit or 64 Bit

To find out if your operating system is 64bit or 32bit, open a
command prompt and type "SET Processor" <enter>. This will show
you all the environment variables that start with PROCESSOR. For
example, if your operating system is 64bit, whether AMD or Intel eith
EM64T extensions, you'll see:

PROCESSOR_ARCHITECTURE=AMD64

On an Intel Itanium you would see:

PROCESSOR_ARCHITECTURE=IA64

Bring the database which is in suspect

Steps intend to do to get the database online:

1. We then execute

Use Master
Go
sp_configure 'allow updates', 1
reconfigure with override
Go
- So that it would allow us to make changes directly to the SYSTEM tables(this option is used in extreme circumstances).

3. The following command lets us put the database in an emergency mode

Update SYSDATABASES set status = 32768 where name = 'SampleDB'
- In Emergency Mode it would allow us to perform certain actions which would not be possible in either Normal or Suspect Modes.


4. Having put the database in Emergency Mode we can then create a new log for the database since the current one can corrupt or inaccessible.



DBCC REBUILD_LOG('SampleDB', ‘C:\Data\SampleDB_newlog.ldf’)
- After this we can check the current files of the database using sp_helpfile command after changing the database context in the Query Analyzer to the affected database

5. We then check for consistency issues on the database by executing:
DBCC CHECKDB('SampleDB')
Go
- If the above command fails it usually recommends the next available option to use. You have to clearly understand the option before you try it since it could result in data-loss

6. Turn off the option to make direct changes to the SYSTEM tables using:
sp_configure 'allow updates', 0
reconfigure with override
Go

7. Then proceeded to take a complete database backup of the database.

Query to find computed columns

AND OBJ.ID = CMT.ID
AND COL.COLID = CMT.NUMBER
AND ISCOMPUTED = 1

How to use Kerberos authentication in SQL Server

On Situation like;

  This could be either because of a network problem (i.e. the machine could not
connect to the domain controller for authenticating the user) or the user
account (KUT01\SQL_rest_test_3 ) running sqlservr.exe does not have
permission to query the domain controller (KU). The later could happen if
sqlservr.exe is running using an domain account
(KUT01\SQL_rest_test_3) different from the user 'KU\SQLService' above 
the machine is on a different domain (KUT01) than 'KU\SQLService' and there
is no two-way trust.

        When you invoke the BULK Insert  from computer T080 , 
         inserting data into SQL Server on  T081\SQLTest03,

         and specifying a data_file on third computer
by using a UNC path         
             \\Box3\Share_Data\

Use below;

SQL Server - How To Tell If There Is A Trace Running

 

Server-side tracing is the process of having your SQL Server machine save events to a physical file on that machine without using the Profiler client tool. Server-side tracing is enabled and controlled by using SQL Server system-supplied stored procedures and functions. With these system-supplied processes, you can identify what to trace, when to start and stop tracing, what traces are running, and view trace information stored in the trace file.


Here is how you view the number of traces currently running:



SELECT count(*) FROM :: fn_trace_getinfo(default)
WHERE property = 5 and value = 1




Here is how you can find more detail about the running traces:

 SELECT * FROM :: fn_trace_getinfo(default)




You can terminate a trace with the 'sp_trace_setstatus' stored procedure using the traceid:

EXEC sp_trace_setstatus 1, @status = 0

EXEC sp_trace_setstatus 1, @status = 2



setting the status to 0 stops the trace
setting the status to 2 closes the trace and deletes its definition from the server

How to reassign the DTS package owner

In most cases, it doesn't really matter who owns the package - who is


executing it is more important. However, there is an undocumented


stored procedure called msdb..sp_reassign_dtspackageowner, which you


can use.

Unable to truncate trans. log after removal of replication.

ACTION: Problems with truncating the transaction log even though the


database is not configured for replication.





RESULT: When truncating the transaction log by executing DUMP TRANSACTION db


WITH NO_LOG the following error was generated:





"The log was not truncated because records at the beginning of the log are


pending replication. Ensure the Log Reader Agent is running or use


sp_repldone to mark transactions as distributed."





Also executing sp_repldone then fails stating, "The database is not


published."





CAUSE: The database has been left in an intermediate state where replication log records is still available in the transaction log even though SQL Server does not have publishing enabled, the database is not published and no objects are marked for replication.





RESOLUTION: Enable publishing again and then run sp_repldone and after that remove replication again.





First, enable publishing:





1. In SEM, choose Tools\Create and Manage Publications





2. Select the database whose log we want to shrink and click Create


Publication





3. Select 'Next' on the Create Publication Wizard





4. Choose Yes, use local machine as the distributor, and then click Next





5. Click OK on any messages that might appear warning that SQL Agent is running under the local system account





6. Select Transaction Replication, the click Next





7. Accept No, do not allow immediate-updating subscriptions, and then click Next





8. Accept All subscribers will be servers running SQL Server, then click


Next





9. Click 'Publish All" then click Next





10. Accept the default publication Name and Description, then click Next





11. Accept No, create a publication without data filters, then click Next





12. Click Finish. Enter the 'sa' password if prompted. Click OK, Close,


Close to exit remaining dialog boxes.





Second, clear log of transactions marked for replication:





13. Login to Query Analyzer as 'sa' and open the database who log we want to shrink.





14. Execute "sp_repldone NULL, NULL, 0, 0, 1"





15. Check that this worked using "sp_repltrans". It may take a little time before all the transactions have been marked as distributed.





16. Execute "dump tran with no_log"





17. Confirm that the log file shrank by running "DBCC sqlperf(logspace)". It may take a little time before the % used shows as decreased.





18. Disable publishing through SEM by choosing Tools= />
Publishing= />

Table error: Object ID
515532920. The text, ntext, or image node at page (1:1124698), slot 1,
text ID 896822476800 is not referenced.

CHECKDB found 0 allocation errors and 8 consistency errors in table 'CC_Document' (object ID 515532920).

CHECKDB found 0 allocation errors and 8 consistency errors in database 'crmproded'.

repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKDB (crmproded ).



Cause:



The text fragments
listed in the CHECKDB output aren't referenced by any rows in the
clustered index. When a data row has a LOB value then usually (unless
you've tweaked the text_in_row option) the LOB value is stored off-row
with a root pointer stored in the data row itself. What's happened in
this case is that some data rows have been deleted but their
corresponding LOB values have not been. This should be benign but we
should try to work out why it happened.
