IEA995I SYMPTOM DUMP OUTPUT 

                

Environment

Z/OS 2.4

IMS 15.4 

IBM RSU2306 or greater + IBM maintenance PH49469

 

Cause

If the system is at IBM RSU2306 or greater, the application of IBM maintenance PH49469 causes 0C4 abends to occur in the IMS region.          

Multiple 0C4 abends occur in the IMS region. The IMS region eventually becomes inactive.                                                                              

Resolution

LU11836 will solve the problem.

Since LU11836 is marked as PE, LU12318 must also be applied.
