IT20124: INTEGRATION NODE ABENDS ON SHUTDOWN AFTER QMGR OUTAGE IF INTEGRATION NODE LISTENER NOT STARTED

APAR status

• Closed as program error.

Error description

• If a multi-instance integration node has been configured to run
  without starting the integration node HTTP Listener, it abends
  on a failover shutdown with the following abend stack:
  
  Windows:
  CommonServices!?lock@ImbMutex
  AdministrativeAgent!?stopHABrokerInstance@ImbBrokerDirector
  AdministrativeAgent!?runBrokerDirectorCleanup@ImbBrokerDirector
  AdministrativeAgent!?run@ImbBrokerDirector
  AdministrativeAgent!?start@ImbBrokerMain
  
  Unix:
  ImbBrokerDirector.ImbMutex::lock
  ImbBrokerDirector::stopHABrokerInstance()
  ImbBrokerDirector::runBrokerDirectorCleanup()
  ImbBrokerDirector::run()
  ImbBrokerMain::start
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus V9.0 and V10.0 who have the
  integration node HTTP listener disabled.
  
  
  Platforms affected:
  z/OS, MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  If the integration node HTTP listener has been disabled such
  that it does not run, an abend may occur if the integration node
  shuts down due to the associated MQ queue manager becoming
  unavailable.
  With IBM Integration Bus (IIB) V9.0 this will only occur if the
  integration node has been configured as a multi-instance or high
  availability (HA) node.
  With IIB V10.0 this may occur for HA and non-HA integration
  nodes if an associated MQ queue manager has been defined for the
  integration node.
  The abend occurs because the shutdown logic attempts to shutdown
  the integration node HTTP listener process without first
  checking that it is running.
  

Problem conclusion

• The product now checks whether the HTTP Listener parameters have
  been set, denoting that it is running, before attempting to shut
  the process down.
