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

  * PROBLEM DESCRIPTION: The CICS link server does not reconnect *
  *                      to a Liberty profile server after the   *

  ****************************************************************
  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
