SSRS Reports Issue after Migration: Invalid object name ‘ReportServerTempDB.dbo.TempCatalog’   4 comments

I recently migrated one of our SQL Server Database Engine and SSRS instances from SQL Server 2008 to SQL Server 2014. Post migration, when I tried to browse the SSRS reports, I get this error:

An error occurred within the report server database.  
This may be due to a connection failure, timeout or low disk condition within the database
. ---> System.Data.SqlClient.SqlException: 
Invalid object name 'ReportServerTempDB.dbo.TempCatalog'.

Powershell script to manipulate SQL Server backup files   Leave a comment


I use Ola Hallengren’s famous backup solution to back up my SQL Server databases. The destination for full backups is a directory on local disk; let’s say D:\SQLBackup\

If you are familiar with Ola’s backup scripts, you know the full path for backup file looks something like:


where InstanceName is a placeholder for the name of the SQL server instance, similarly, DatabaseName is for the Database Name. Read the rest of this entry »

Learn n Win : Presenting on “SQL Server Dump Analysis” at PASS DBA Virtual Chapter   6 comments

pass_vc_dba_logoI am excited to be speaking at PASS DBA Virtual Chapter on Wednesday Jan 14th. Here is the topic, abstract and schedule of the session:


While dealing with SQL Server administration, you might have come across scenarios when a  session terminates abruptly, SQL Server instance crashes, SQL Server cluster fails over without a  graceful message. Most often, it leaves a dump file behind which is unfortunately not in a human readable format. In this one hour session, you will learn the basics of a dump file, the tools available for reading thru a dump, the different types of dumps and demos on various debugger commands, how to analyze a dump file to establish the root cause.

DateJanuary 14th 12:00 noon Mountain time (click here to see it in your local time)

If you are a SQL Server DBA willing to dig into dump files which you can’t read just like you read the ERRORLOG, come and join us on this Wednesday Jan 14th to find the exciting stuff. This is a FREE session, you just need to be a member of PASS in order to register. You also stand a chance to win a $100 gift card from Amazon once you register for the session. The winner will be declared through a draw.

Registration: You must register if you want to attend. You can register here

We already have a number of registrants. Hurry up and do share and tweet about this.

See you on Wednesday!
Happy learning!!

Why is affinity mask negative in sp_configure   Leave a comment

While looking at a SQL server health report, I found affinity mask parameter in sp_configure output showing a negative value.


name                                minimum     maximum     config_value run_value
----------------------------------- ----------- ----------- ------------ -----------
affinity mask                       -2147483648 2147483647  -1066394617  -1066394617


This output was from a SQL Server 2008 R2 instance running on Windows Server 2008 R2.


Affinity mask is a SQL Server configuration option which is used to assign processors to specific threads for improved performance. To know more about affinity mask, read this. Usually, the value for affinity mask is a positive integer (decimal format) in sp_configure. The article in previous link shows an example of binary bit mask and corresponding decimal value to be set in sp_configure. Read the rest of this entry »
