Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• In certain situations a
  
  CEMT PEFORM PIPELINE(value) SCAN
  
  command results in an abend0c4 in libdfhcdjni.so and CICS
  region termination.
  
  The problem occurs when the pipeline scan is done when there is
  work in flight for a Webservice that will be updated as a result
  of the scan.
  
  In the reported case the pipeline involved utilizes an Asix2
  JVM server.
  

Local fix

• If customer does have a period where there is no work in
  flight,the pipeline scan should complete normally.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS Users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: An abend0c4 in libdfhcdjni.so and CICS  *
  *                      terminates following a manual PIPELINE  *
  *                      SCAN of the wsbind directory.           *
  ****************************************************************
  CICS provides support via command:
  
  CEMT PERFORM PIPELINE(value) SCAN
  
  to initiate a scan of the web service binding directory.
  
  If work for a pipeline is running, when the update of the
  Webservice is requested, the update can be deferred until the
  request has completed in CICS.
  
  The update of the Webservice can result in a switch of TCB and
  in some circumstances, this can result in a return from a JNI
  call on the QR, which will cause an abend0c4.
  
  The problem can only occur for Java based pipelines.
  
  KEYWORDS: JVMSERVER PIPELINE libdfhcdjni.so
  

Problem conclusion

• CICS pipeline code has been updated to prevent the abend0c4 when
  updating the Webservice in a Java based pipeline.
  

Temporary fix
