You probably analyzed the SYS tables when there was hardly any acitivity 
on the database. The fixed objects should be analyzed after you the 
workload is sufficiently ramped up.

        Subject:        Querying v$ tables very slow after upgrade


After upgrading our production database from 9.2.0.7 to 10.2.0.3 yesterday 
we are having severe performance problems when trying to query
any dba_* view or v$* view.

I checked and stats were gathered for all SYS tables during the upgrade, 
the last_analyzed date is the time of the upgrade.

Does anyone have any experience with this?

Thanks,

Patty
