Situation Description

IRLM use of RLEs is high

 

Suggested Actions

The IRLM system uses an RLE control block for keeping track of lock owners and waiters. There is a finite number of these control blocks available. If the utilization of this area goes to 100%, then requests for locks in the IRLM will fail causing either delays in the applications or termination of those applications. The applications currently holding the locks should be verified to make sure they are acting properly and releasing the locks after they are done with the pages.
