Error description

  • When the z/OS Connect instance is stopped/started we get the
    abend in the BBOATRUE running in CICS at the time of the
    WOLA
    rebind. z/OS Connect 2.0.7, WLP 16.0.0.3, Angel version 5
    
    IEA794I SVC DUMP HAS CAPTURED:  260
    DUMPID=010 REQUESTED BY JOB (XXXXXXX)
    DUMP TITLE=COMPON=WEBSPHERE Z/OS,
    COMPID=5655I3500,
    ID=server_wola_client_rebind.wolaClientRebind()
    

Local fix

  • A work around is to stop the CICS region (or stop the WOLA
    connection) before stopping/restarting z/OS Connect. Then
    restart CICS (or WOLA connection).
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty for z/OS                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: An SVCDUMP occurs when a WOLA client    *
    *                      such as CICS attempts to re-connect to  *
    *                      a Liberty server that has been          *
    *                      restarted.                              *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    A client such as CICS might maintain a connection to a Liberty
    server using WOLA for a long period of time.  If that Liberty
    server is recycled, the client can automatically re-connect to
    the new instance of that server when it is restarted.  The WOLA
    CICS link server that ships with Liberty is one example of a
    client that does this.  In some cases, if the Liberty server
    cannot process new connection requests quickly after it is
    restarted, the client may produce an SVCDUMP.  The client should
    retry the connection attempt rather than take an SVCDUMP.
    

Problem conclusion

  • Code was added to the WOLA CICS link server to be more tolerant
    of timeouts that can occur when establishing connections between
    a WOLA client and Liberty server.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.2.  Please refer to the Recommended Updates page for
