PI09918: USING AXIS2 WEB SERVICES RESULTS IN A BUILDUP OF AXIS2.LCK TEMP FILES.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When using AXIS2 Web Services there appears to be a buildup of
  AXIS2.lck tmp/files that do not get cleaned up using up space
  in the z/FS /tmp directory
  
  
  
  
  
  
  
  
  Additional Symptom(s) Search Keyword(s): KIXREVRHC
  CICS hangs at shutdown. The Kernel stacks for the CEMT
  shutdown task show that DFHSJIN is processing a
  TERMINATE_JVM_ENCLAVE request. The corresponding TP TCB has
  been put into a wait by DFHSJIN. CICS issues a DestroyJavaVM()
  call which will only terminate the JVM once all non-Daemon
  threads have completed. JDMPVIEW shows that the DestroyJavaVM
  process is waiting for the CICSThreadExecutorTidyUpThread to
  complete. This thread is marked as a non-Daemon thread. This
  APAR changes this to be a Daemon thread and this change will
  prevent this thread from holding up the JVM shutdown.
  

Local fix

• Use a UNIX System Services CRON job to cleanup old tmp/files
  manually.

  ****************************************************************
  The Apache Axis2 Web services implementation creates work
  files in the /tmp directory. These files consist of
  subdirectories named axis2-tmp-*.tmp and lock files named
  axis2-tmp-*.tmp.lck. In CICS, JVM never goes through a normal
  termination, the lock files are not deleted. Then the temporary
  files will not be cleaned up when a new Axis2 Web services
  request is received, resulting in using up space in the zOS
  /tmp directory.
  

Problem conclusion

• DFHSJSC has been changed to ensure the JVM goes through a
  normal termination under normal circumstances, so that
  temporary files are cleaned up.
