Error description

  • When asynchronous I/O support is configured on z/OS,
    messages CWWKO0229I and CWWKO0230I may not be issued.
    Asynchronous I/O support is not active at runtime, even
    though message CWWKB0103I indicates authorized service group
    ZOSAIO is enabled.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Liberty for z/OS                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: Asynchronous I/O support is disabled at *
    *                      runtime, despite it being configured.   *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    In some cases, message CWWKB0103I indicates that the ZOSAIO
    authorized service group is available, but messages CWWKO0229I
    and CWWKO0230I are not issued.  In this case, the asynchronous
    I/O libraries are not available at runtime, and the server will
    operate using the standard I/O routines.
    

Problem conclusion

  • Code was added to ensure that the asynchronous I/O service is
    started when it is configured.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.3.  Please refer to the Recommended Updates page for
