Issue/Introduction

I upgraded to CA Datacom version 15.1 .
When using SYSVIEW for Datacom I get the following message when accessing any of the options other than DCLIST: 

DCOM006E OPEN request failed, RC 25, RS 20, FC 16, Job MUFTESTU

Environment

Z/OS 
CA Datacom 15.1  
CA SYSVIEW 14.1

Cause

Using another DBID than the default  DBID 1000 for database CASYSTEMTABLES.   
MUF uses SYSTEMDBID 998.

Resolution

In CA SYSVIEW PARMLIB(DATACOM) ,code your DBID (998 in this case) in SYSTEMTABLE.
Check also that your  SYSVIEW region is running using the DBSVWPR module from Datacom 15.1 PTF RO88530.
