Hi, guys.
We were getting killed on SAP, when checking locks, after we
upgraded to 9.2
One of the other DBAs came up with this and it was a dramatic
improvement. Not sure if he got it from metalink or?
We just upgraded a 8.1.6 database to 9.2 and had the same problem.
This fixed it.
He also had this comment "Has anyone tried selecting a particular
extent out of dba_extents, on the SAP systems I'm seeing horrendous
performance"
Are there any other views that we should be replacing?
Thanks
Larry
