PI97320: CICS GOES INTO A LOOP AFTER STARTING A 2ND JVMSERVER 19/01/21 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A CICS region goes into a loop as soon as a second JVM server
  is started. The problem started to appear after installing
  RSU1803.
  .
  The systrace shows that the loop happens in modules IGC0003C
  and IGVVSTOR.
  
  The following message appears once the 2nd JVM is started:
  
  CWWKB0101I: The angel process is not available. No authorized
              services  will be loaded. The reason code is 260.
  
  A reason code 260 means a Liberty server by that name is
  already connected to the angel process.
  
  It appears that the option WLP_ZOS_PLATFORM=FALSE is ignored
  and that it still tried to connect to the angel process.

  * PROBLEM DESCRIPTION: Liberty JVM server with                 *
  *                      WLP_ZOS_PLATFORM=false incorrectly      *
  *                      connects to the Liberty angel process.  *
  ****************************************************************
  If a JVMProfile has WLP_ZOS_PLATFORM=false set then when the
  Liberty JVM server starts up it incorrectly connects to the
  angel process. This can lead to unpredictable errors during the
  lifetime of the Liberty server.

  that it does not connect to the angel process.
