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::~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. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v10.0 10.0.0.21 The latest available maintenance can be obtained from: http://www-01.ibm.com/support/docview.wss?rs=849&uid=swg27006041 If the maintenance level is not yet available,information on its planned availability can be found on: http://www-1.ibm.com/support/docview.wss?rs=849&uid=swg27006308 ---------------------------------------------------------------
