CXPacket isn’t the cause, it is a symptom

Beware of Diskeeper 10 on your servers

Denny Cherry Denny Cherry Profile: Denny Cherry

Everyone likes nice defragmented SQL Servers.  However if you use Diskeeper to do so be very careful before you upgrade to the new version 10, or if you are going to upgrade to the new version 10 you’ll need to make a small change to your configuration on each SQL Server.

OPENXML can be a beast sometimes.

A little while back I posted about how to move a standalone instance to a clustered instance using a different name and IP, but what do you do when you need to keep the same name and IP address?  This is a much more complex procedure to complete. Continued »
