Hi I have been having database performance issues possibly related to unexpired objects in the database. The problem manifests itself with all the client sessions during the backup window grinding to a halt. There are 7 pages of locks on the database and nothing is moving. After running expiration, which expired 60% of the objects that is analysed, the problems goes away.
Can anyone tell me how to work out the actual number of objects in the database? Also, once the expiration process complete- I ran it again, immediately and it found another few hundred thousand objects to expire- why? Has anyone else seen this type of problem? If so is there a statement that can be written to analyse the number of unexpired objects that currently reside in the database? As light weight as possible, as a heavy weight global lock enforced by a big statement probably wont complete when the system is under this massive load!
