APAR status

  • Closed as program error.

Error description

  • Steps I did are:
    on zOS LPAR had these STCs running:
    WANGEL - Liberty angel started task
    WALS01A - zOS Connect Liberty server started task
    CICSPAZ3 - CICS region
    Everything up and running, and I can send REST/JSON connect
    to
    WALS01A,  which then sends request via WOLA to the CICS
    region
    and reply comes back all ok.
    .
    I then cancelled WALS01A and restarted it.
    This is then the problem, the registration from CICSPAZ3
    does
    not reconnect to the WALS01A server automatically, happens.
    

Local fix

  • stop and then restart the relevant CICS region

    ****************************************************************
    A CICS link server connects to a Liberty server instance by
    using the "BBOC STA" transaction.  If the Liberty server
    instance stops, the following message is printed in the CICS
    JOBLOG:
    CWWKB8051E: The XXX link server lost the connection to the
    following server instance: YYY
    
    When the Liberty server restarts, the following message should
    be printed to the CICS joblog to show that the link has been re-
    established:
    CWWKB8052I: The XXX link server re-established the connection to
    the following server instance: YYY
    
    Message CWWKB8052I is not shown in the CICS joblog, and the link
    between CICS and Liberty is not re-established.
    

Problem conclusion

  • Code was added to re-establish the link between the CICS link
    server and the Liberty server instance, when the Liberty server
    is restarted.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 8.5.5.9.  Please refer to the Recommended Updates page for
