Hi there, can someone please explain to me why is IMS returning GC's, I read the status explanation but cannot really understand what the unit-of-work is. Is the IMS jumping from one area to another area.

I will really appreciate any responses.

Hello and welcome to the forum,

Probably not, but the program code might be. . .

Is this the same status explanation you read:
http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/handheld/Connected/BOOKS/dfsmc4h2/8.2.2.78

Is this a new program (or a newly modified program)?

Tha's exactly the same status description that I have, this is an existing program and it has logic to handle the GS's, every number of GC's it does a checkpoint. I would like to really understand why is the GC returned by the IMS

Look up FR status code. You will see this:
Quote:

Programmer Response: Either terminate the program and restart it with a larger buffer allocation, or provide a routine that causes frequent commit points. If PROCOPT=H is used, make sure that a commit point is requested after a GC code has been returned.

Well, I have never written a program that EXPECTS a naughty status code.

Thank you Sandy, I appreciate your help. I'll keep looking for information that tells me exactly what the GC code means and will post it her.

thanks

The manual is rather explicit.

Suggest you have a talk with your dba and possibly this will lead to a better understanding.
