PH39247: CICS BUNDLE APPLICATIONS STARTING SEQUENTIALLY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Applications installed into a Liberty JVMSERVER using CICS
  BUNDLE resources are started sequentially.  This is most
  noticeable when applications take many seconds to start and
  deferServletLoad="false" is set in server.xml.  In such cases
  the CWWKZ0018I and CWWKZ0001I messages written to messages.log
  by Liberty will have the following pattern:
  
  [7/20/21 8:45:40:535 GMT] 0000006b
  com.ibm.ws.app.manager.AppMessageHelper                      I
  CWWKZ0018I: Starting application app1.
  [7/20/21 8:45:45:645 GMT] 0000006b
  com.ibm.ws.app.manager.AppMessageHelper                      A
  CWWKZ0001I: Application app1 started in 5.109 seconds.
  
  [7/20/21 8:45:45:757 GMT] 0000006b
  com.ibm.ws.app.manager.AppMessageHelper                      I
  CWWKZ0018I: Starting application app2.
  [7/20/21 8:45:50:826 GMT] 0000006b
  com.ibm.ws.app.manager.AppMessageHelper                      A
  CWWKZ0001I: Application app2 started in 5.069 seconds.
  
  [7/20/21 8:45:50:834 GMT] 0000006b
  com.ibm.ws.app.manager.AppMessageHelper                      I
  CWWKZ0018I: Starting application app3.
  [7/20/21 8:45:55:914 GMT] 0000006b
  com.ibm.ws.app.manager.AppMessageHelper                      A
  CWWKZ0001I: Application app3 started in 5.079 seconds.
  
  The thread identifier, 0000006b in the above example, shows the
  applications all use the same thread one after another to start.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: WAR, EBA and EAR applications deployed  *
  *                      to a Liberty JVMSERVER using BUNDLE     *
  *                      resources start sequentially.           *
  ****************************************************************
  WAR, EBA and EAR applications are installed into a Liberty
  JVMSERVER using BUNDLE resources.  The BUNDLEs are enabled
  causing CICS code running in the JVM to call Liberty to start
  the first application.  The first application initialises using
  the thread that made the start call.  As a result CICS is unable
  to call Liberty to start the second application until the first
  application has completed initialisation.
  
  This problem is most evident when the webContainer element
  in server.xml specifies deferServletLoad="false" or the
  applications take many seconds to start.
  

Problem conclusion

• CICS has been updated so that WAR, EBA and EAR applications
  deployed to a Liberty JVMSERVER using BUNDLE resources are
  started in parallel using threads from the CICS Liberty thread
  pool.
