JR45581: SAP ADAPTER (INPUT NODE, IDOC PROCESSING) V7.5, WMB V8001 - WORKREJECTEDEXCEPTION IF FLOW GETS RESTARTED

APAR status

• Closed as program error.

Error description

• Environment:
  ------------
  - Websphere Message Broker 8.0.0.1 with SAP Adapter version 7.5
  - SAP input node processing iDocs (ALE)
  
  Behaviour:
  ----------
  If such a message flow gets stopped, and then restarted (without
  restarting the Broker) then no new IDocs can be sent from SAP
  anymore.
  
  The Broker service trace does show below exception:
  
  2013-01-21 10:25:32.360856    43748                        >>
   MbErrorHandler.traceThrowable 'caught WorkException in
   MbWorkManager.doWork' ,
   'javax.resource.spi.work.WorkRejectedException
    at com.ibm.broker.jca.MbWorkRequest.reject(MbWorkRequest.
       java:132)
    at com.ibm.broker.jca.MbWorkManager.doWorkInner(MbWorkManager.
       java:171)
  
  On SAP side the RFC logical unit of work table (SM58 in SAP GUI)
  does show a failure for each IDoc LUW started after the restart
  of the message flow:
  
   javax.resource.ResourceException:
    javax.resource.spi.work.WorkRejectedExc
  

Local fix

• 1. It is necessary to restart the Execution Group, or the whole
     Broker to get the Adapter input node working again.
  
  2. Execute all that failed SAP LUWs again from SM58 list which
     do show a ...WorkRejectedExc
  

Problem summary

• In WMB, when flow is restart and next subsequent requests throw
  WorkRejectedException since the new workmanager from WMB was not
  used
  

Problem conclusion

• The endpoint manager is cleared during endpointDeactivation.
  fixed in 7.5.0.2_IF03
  

Temporary fix
