Issue/Introduction

When starting the MUF, I received errors about the SYSPLEX name:

DB00912E - CXX SYSPLEX x DOES NOT MATCH CURRENT SYSPLEX y
DB00501E - OPEN ERROR - RETURN CODE 47 (008) CXX=cxxname  (CXX     )

How do I change the SYSPLEX name in the CA Datacom Multi-user (MUF) and the CXX to correct this?

Cause

Executing the MUF on an LPAR different from the LPAR where the installation jobs were run.

Environment

Release : 15.0

Release : 15.1

Component : CA Datacom/AD

Component : CA Datacom/DB

Resolution

In order to correct the SYSPLEX name, both the MUF and the applications using the MUF must not be running.

There are two ways to update the CXX with the correct SYSPLEX name: 

  1. Run DBUTLTY with this input:
    //SYSIN    DD  *
    CXXMAINT OPTION=ALTER,OPTION2=MATCHSID
    /*
    This will assume the SYSPLEX name from the system where the job was run.

  2. Run DBUTLTY with this input:
    //SYSIN    DD  *
    CXXMAINT OPTION=ALTER,OPTION2=MATCHSID,OUTNAME=sysplex-name
    /*

    This will assume the SYSPLEX name from the system where the job was run. Sysplex-name must be the SYSPLEX name for the LPAR where the MUF will execute.

Additional Information

This DBUTLTY job must run with the MUF down. Otherwise, the job will receive this error:

DB10053E - MUF RUNNING, FUNCTION REQUIRES MUF DOWN 

For more information about the CXXMAINT function, please refer to the CA Datacom documentation for CXXMAINT ALTER OPTION2.
