System Databases Tips

It has come to my attention that some of our MSDB databases are getting what I would consider large for a system database. Some of our MSDB databases are over 2 GB which is a little perplexing because I know we do not create any user defined objects in that database. Can you give me some insight into the issue? I know we have this issue with both SQL Server 2000 and 2005 instances.

One task that you may need to do as a DBA is to move the system databases from one location to another. The documentation that is found on the Microsoft site is helpful, but the steps are more geared toward moving one database at a time. In this tip we look at a streamlined process of moving all system databases at the same time.

Properly sizing the TempDB database has recently surfaced with some new customers and has also been a thread (http://blogs.mssqltips.com/forums/t/64.aspx) posted in the MSSQLTips forums. Here is the general scenario: On all of my SQL Server instances (development, test and production) the TempDB database is configured for auto growth for the database and transaction log. During a recent performance tuning engagement I learned a lot about how TempDB is being used in my environment. It was brought to my attention how much the TempDB database is being used by our applications. I had no idea our core business applications are using the TempDB database so heavily. In addition, I did not know how large the TempDB database and transaction...

I have seen the Master, Model, MSDB, etc. databases in Management Studio and in a variety of scripts. Right now I have a fairly rudimentary set of knowledge about these databases just based on reviewing those scripts. As I expand my SQL Server knowledge, I am interested in learning more about the SQL Server system databases and how I can use them to help me on a daily basis. I am sure their are many recommendations when working with these databases and I am interested in those as well.

Tempdb plays an important role on SQL Server performance. A tempdb database that resides on a slow set of disks or a tempdb database that has been sized incorrectly may have an overall impact on query performance. In this tip I will go over some best practices for performance related to Tempdb.

We are using SQL Server 2008 and the server has a lot of performance issues that seem to be related to a saturated tempdb database. TempDB on this server is heavily used by creating and dropping many temp tables and work tables. How do I effectively find out if the Tempdb database is suffering from an allocation bottleneck? Should I create multiple TempDB files per core on this server to improve performance? How do I check this information programmatically?
