BMP program caused to bring down the control region

Post by rahul_kolhe » Mon Nov 13, 2006 1:48 am


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.

Thank you.

S322 Abend

Hi Rahul,

Time parameter change should work for S322 abend.....

There are two solutions i can suggest here.

1. Use TIME=NOLIMIT or 1440 , you are already tested this....
2. Check the class you are using, system group
specifies time limit for each class type.
job abend occurs if standard time limit specified in the job entry
subsystem crossed.
we need to contact system people for this.

Hi Krish,

I have changed the JCL and coded the TIME=1440 which solves S322.

My doubt is that could BMP step abend S322 bring down the complete IMS region. And is it advisable to not code TIME parm on BMP step or to code TIME=1440?

This happened mistakenly. But there are occurances when we test some programs with lesser input or giving TIME parm so that can check whether program is not looping.

If a region that is abending is in a DLI call, will kill the control region. The control region will abend with U113. Look in the IMS messages for U113 for more information.
