Issue/Introduction

CA Datacom MUF environment running in z/VSE 6.2  got upgraded from version 11.0 SP5 to 12.0 .

After running for a couple of hours the MUF abended with:

F4 0004 CEE3322C EXECUTION ABNORMALLY TERMINATED WITH USER-ABEND CODE 4093 AND                                       
         REASON CODE 0056.                                                                                           

Environment

Release : 12.0

Component : CA DATACOM/DB for z/VSE 

Cause

z/VSE LE/370 default value  for LE option ALL31 is not good for the MUF.

Resolution

CA Datacom 12.0 uses IBM-C and not CA-C anymore.

The z/VSE LE/370 default value for ALL31 is  ALL31=((OFF),OVR)  and the HEAP Default value is  HEAP=((32K,32K,ANYWHERE,KEEP,8K,4K),OVR). 

That is not what  is needed for the Datacom MUF .

The goal is to run as much as possible in 31 bit memory. 

Override the default LE system values by starting the MUF using following PARM:

00243 // EXEC DBMUFPR,SIZE=DBMUFPR,PARM='ALL31(ON),STACK(12K,4K,ANY,KEEP),', X 
00244                 PARM='RPTSTG(OFF),RPTOPTS(OFF)/'
