Long waits 

High GRS waits

Question:

After we upgraded to R19 

we started experiencing High GRS waits on the system?

What could be causing this?

Environment:
z/os
Answer:

This could be caused by a latching problem in the Xmanager address space. 

Turn off latching within Detector and Subsystem Analyzer

 

Just add a PARM LATCH (N) to both PDT and PSA members in the CDBAPARM library
