Snap file is created automatically on my SharePoint database ?

March 5, 2014, 2:56 am

Hi,

On My SharePoint Database a snap file is created which consumes lots of space and the performance of server is degraded.

The snap file is created automatically and its also removed automatically after 1 day.

I am new to SQL and won't find any scheduled task for snap file under SQL .

I had checked on technet and won't find an appropriate solution, why snapshot file is created.

The SQL server version is 2008 R2 and SharePoint version is 2013.
Also due to snap file sometime I am unable to take backup of database with DPM (Data Protection Manager).

Thanks,

Nadeem A

Database backup

Hello

I've came to situation where I can not find who is backing up the server. :)

At a specific time database get backed up with two tools. One is known, another is the one that needs to be tracked.
Windows logs show these backups as a regular SQL backups, nothing special about these.
SQL trace shows that backups as a backup with following info

BACKUP DATABASE [DBNAME] TO VIRTUAL_DEVICE='{GUID comes here}' WITH SNAPSHOT,BUFFERCOUNT=1,BLOCKSIZE=1024,COPY_ONLY

SQL Trace shows that backups are done with LocalSystem account and hostname is server name.

I can not find any jobs that might start such backups. Also Backup admins say that they have one tool configured for backups (the known one). And Sharepoint Admins say that database backup is not enabled it the settings (I've checked in SP 2013 you can configure Content DB backup from Sharepoint administration).

Maybe someone can advice how to track down that application, which is doing backups?

Thanks.
Olegas

Provider to link to Oracle server

March 5, 2014, 1:11 pm

I have a question relating to compatability, and the Microsoft documentation seems unclear. Here are the system specs:

Windows Server 2008 R2 (64 bit) Standard

SQL Server 2008 R2 (64 bit) Standard

The desire is to link to an Oracle server. It appears I can possibly use:

Oracle Provider for OLE DB: http://technet.microsoft.com/en-us/library/ms190618(v=sql.105).aspx

or

Microsoft OLE DB Provider for Oracle: http://msdn.microsoft.com/en-us/library/windows/desktop/ms675851(v=vs.85).aspx

We've had issues trying the first one. When I looked closer (and found above link) its suggested that the Oracle provider is not compatable with our system? 32 bit Oracle driver does not work with 64 bit SQL server:http://support.microsoft.com/kb/2555855/en-us and it appears 64 bit driver is simply "None" for support.

Can anyone confirm Which driver(s) I can use given my setup? It looks like the Microsoft driver may be the only compatible driver for our setup. The message regarding it being a discontinued feature concerns me.

SQL Query fails with Fetch error

We are running JDE ERP 9.0 and have a report that gets this error

“JDB3300020 - Fetch not allowed. Prior successful Select operation required for this request.”

I’ve been troubleshooting this problem for months, and I am no closer to the root cause and need some help. I’ve engaged Microsoft support, we collected a trace but could not find anything that pointed to the cause.

Execution details:

Report runs successfully after database server is rebooted. Otherwise we have to keep rerunning as many as 15 times to get a successful run. When we discovered that report would run after the server reboot, we decided to only restart SQL, to see if it was Query plan related but it still failed. How can we determine why the reboot is making a difference?

Any ideas/help is welcome.

Issue with Merge command not finishing

SQL Server Standard 2008 R2

I have a rather complex MERGE command with when matched, not matched target, and not matched source.  It runs just fine on a data set of 360K rows, but does not complete on a 500K data set.  sp_who2 indicates millions of pagelatch_sh waits.  Yet if on that same data set, I break the Merge up and run each part individually (insert, update, delete) they each run very quickly.

Has anyone seen this before?

Transaction log usage grows due to replication even if I don't use replication at all

Hi

The transaction log usage keeps growing a lot on my user database since few days back. the database is in full recovery model and I do transaction log backups every 10 minutes. The DB was part of Database Mirroring but I removed it. The usage was controlled for many years by the backups but something happened that is messing up the transaction log

this is DBCC OPENTRAN

Transaction information for database 'MyDB'.

Replicated Transaction Information:
        Oldest distributed LSN     : (0:0:0)
        Oldest non-distributed LSN : (1450911:6823:1)
DBCC execution completed. If DBCC printed error messages, contact your system administrator.

log_reuse_wait_desc reports REPLICATION

the funny thing is that I am not using replication at all. I am using CDC.

To reduce the transaction log usage I run below statement every day since the problem started

EXEC sp_repldone @xactid = NULL, @xact_segno = NULL, 
    @numtrans = 0, @time = 0, @reset = 1

Any idea what should I do to solve this problem and be back on a normal situation?

BTW, The server is SQL 2012 (11.0.2383)

SQL Server Management Studio 2008

Microsoft SQL Server 2008 (SP3) - 10.0.5512.0 (Intel X86)

Aug 22 2012 15:16:00

Copyright (c) 1988-2008 Microsoft Corporation

Enterprise Edition on Windows NT 6.0 <X86> (Build 6002: Service Pack 2) (VM)

When signed into the server using an account other than the local administrator on the machine I try doing a query with the results going to the grid.  I receive the error

An error occurred while executing batch. Error message is: The directory name is invalid.

I have tried uninstalling and reinstalling the client tools with no luck in fixing the issue.  I have also tried changing the directory to the directory of the local machine that I know exists and the user has access to.  This has not solved the issue either.

The server is a Windows Server 2008 Enterprise Edition with a 32-bit operating system.

Any help would be greatly appreciated.

Let me know if you have any questions.

Thanks
