 |
|
Hi Board,
I have got an ABEND while running the IMS Database Loading program when the IMS region is DOWN.
I saw in the Quick Reference regarding this Abend. It has been given that
| Quote: |
--> An attempt was made to schedule a dependent region after a /CHE FREEZE or /CHE DUMPQ command was issued.
--> A BMP or MPP was started after a shutdown checkpoint had already
quiesced and stopped all other active regions.
--> A BMP or IFP scheduling detected an IRLM that is not available and
scheduling cannot continue.
|
Anyone can explain me regarding IRLM. What does it mean? Where can we found it?

IRLM is the "Lock Manager" that controls locks and latches to IMS segments. It prioritizes access to the resource based on access intent (PROCOPTS and call type) and is also responsible for timing out lock requests.
It runs as a started task and may also be shared with DB2.
The name is a combination of the IRLMNM and IMSID parameters (These are either coded in the control region PARM list or in the DFSPBxx member), |
