Hi,

I have a situation where a BMP program bring downs a IMS control region. When we investigated found that STEP has a Time parameter coded with TIME=(10,1). This program scan the database extensive. But when program abended with S322 it cause to bring down IMS control region down in production environment.

One of the solution was recommended that do not code TIME parameter on BMP step or code TIME=1440.

But when I tried to simulate same situation in Test it is not bringing down the test control region. I doubt on the solution recommended. Could someone help with this as this happened thrice and got escalated on very higher level.

Thank you.

Test environment may differ than Production in various attributes. For e.g. CLASS parameter may not be same for both.

If it abends with S322, coding TIME=1440 or NOLIMIT should do.

It was S322 Time out on BMP job. When we investigated we found something about TCB address.

Yes,
I understand the Abend code that brought down the BMP was a S322.
But I need to know what Abend code (user or system) brought down the IMS control region.
I suspect it is a USER (IMS issued) abend. Probaly a U0113.
The only way I can help you is if you give this information.
Look in the syslog at time of error. You should see a DFSxxxxx message that states "purging OLDS buffers". That is the first sign of an IMS dieing.
Right after you should see the ABEND info.

Thanks
