PH01179: DUPLICATE ENTRIES OF THE BBGZSCFM MODULE LISTED IN LPAMAP

Subscribe

You can track all active APARs for this component.

 

APAR status

  • Closed as program error.

Error description

  • BBGZSCFM modules entries in the LPA are not being cleaned up
    correctly upon server shutdown.
    

Local fix

  • Remove duplicate entries:
    1) Always use dynamic LPA DELETE with caution(!)
    2) Dynamic LPA DELETE does distinguish a BYADDR case and is
    smart enough not to delete the module in this case
    We suggest trying to delete one entry and checking the results
    before deleting all N-1 of them.
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty for z/OS                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: The IPCS LPAMAP command shows multiple  *
    *                      entries for BBGZSCFM, BBGZAFSM and      *
    *                      BBGZADRM.                               *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    Output of the IPCS LPAMAP command shows extra entries for
    BBGZSCFM, BBGZAFSM and BBGZADRM because the CSVDYLPA
    REQUEST=DELETE service is being called incorrectly.  BBGZSCFM
    entries added by calling CSVDYLPA REQUEST=ADD are not being
    cleaned up correctly on server shutdown.  BBGZAFSM and BBGZADRM
    entries added by calling CSVDYLPA REQUEST=ADD are not being
    cleaned up correctly when new versions are loaded.
    
    The extra entries do not effect the runtime and there are no
    extra copies of BBGZSCFM, BBGZAFSM, and BBGZADRM in storage.
    The call to CSVDYLPA REQUEST=DELETE for BBGZSCFM, BBGZAFSM and
    BBGZADRM is using the wrong parameter list mapping and is not
    setting the module name that is a required parameter.
    

Problem conclusion

  • Updated the code to call CSVDYLPA REQUEST=DELETE correctly for
    BBGZSCFM, BBGZAFSM, and BBGZADRM.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 18.0.0.3.  Please refer to the Recommended Updates page for
