Issue/Introduction

Running Datacom 15.1 and the MUF abends with a S0F4 reason code 24

Restarted the MUF and it abends with the same S0F4-24 error after message DB00248I while loading modules:

 DB00248I - PARM PGMDT=20151231, DBMLBPR  2020/08/18-1311 15.1  SO14507
 DB00248I - PARM PGMDT=20151231, DBSIPPR  2020/07/22-1840 15.1  SO14115
 DB00248I - PARM PGMDT=20151231, DBSSPPR  2020/09/08-1823 15.1  SO14542
 IEA995I SYMPTOM DUMP OUTPUT
 SYSTEM COMPLETION CODE=0F4  REASON CODE=00000024

Cause

At the time of the failure Datacom is loading modules from the loadlib. 
In this case the S0F4 is issued by IBM module IGWIRPGD which is part of DFSMS. 
An S0F4 abend can be caused by a corrupt PDSE library.

 

Environment

Release : 15.1

Component : DATACOM/DB

Resolution

Check the load libraries in the STEPLIB. If a PDSE library is corrupt it will have an error when trying to browse it in ISPF.

It is most likely the Datacom load library CABDLOAD (for DB)  or CAAXLOAD for (AD) containing the Datacom system  modules that has the problem.

Try using a Datacom 15.1 loadlib from another MUF or restore the library from a backup.
