IT30813: UNDEPLOYING A MESSAGE SET IN AN INDEPENDENT STATIC LIBRARY CAN TRIGGER ABENDS IF USED BY AN INDEPENDENT MESSAGE FLOW

APAR status

• Closed as program error.

Error description

• It is possible to deploy the same message set to an integration
  server multiple times if they are put in differently named
  static libraries and are only consumed by an independent
  message flow. In this case abends during message processing or
  on integration server shutdown can occur if one of these static
  libraries is undeployed.
  

Local fix

• Do not deploy two static libraries which both provide the same
  message set to the same integration server
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus v10 who deploy MRM message sets
  in static libraries as independent resources which are used by
  message flows which are also deployed as independent resources.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  If an MRM message set is deployed to an Integration Server as an
  independent resource in a static library, and is then used by a
  message flow also deployed as an independent resource which is
  not in the same static library, then attempting to use the MRM
  parser again in the message flow after undeploying the static
  library will trigger an abend. An abend will also be triggered
  if the flow is stopped or undeployed in a separate configuration
  action after undeploying the static library. This is caused by
  the MRM parser maintaining references to memory owned and freed
  by the message set.
  
  The abend stack will contain entries similar to the
  following:<p>
  #5  0x7f566e98d751 in ImbSemaphoreBase::Semaphore::lock() from
  /appl/IBM/iib/iib-10.0.0.14/server/lib/libCommonServices.so</p><
  p>#6  0x7f566e98d88d in
  ImbSemaphoreBase::Semaphore::Semaphore(ImbSemaphoreBase&,
  ImbSemaphoreBase::Semaphore::State) from
  /appl/IBM/iib/iib-10.0.0.14/server/lib/libCommonServices.so</p><
  p>#7  0x7f55d40bedac in
  CpContext::releaseWorkerAndDictionary(CpContext::Operation,
  bool, bool) from
  /appl/IBM/iib/iib-10.0.0.14/server/lil/MtiImbParser.lil</p><p>#8
    0x7f55d40beeca in CpContext::&#126;CpContext() from
  /appl/IBM/iib/iib-10.0.0.14/server/lil/MtiImbParser.lil</p>
  

Problem conclusion

• The product no longer abends under these conditions.
