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
