PH52751: CICS Bundle Deploy API Temp directory fills up the USS filesystem.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Using Bundle Deploy API to deploy bundles into CICS, after some
  time the USS filesystem where the bundle deploy temp files are
  stored filled up. This location is set in the WUI JVMProfile by:
  
   com.ibm.cics.jvmserver.cmci.tmp.dir=
  
  The tmp files should be cleaned after deployment.

  * USERS AFFECTED: All CICS Users                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: Temporary files created by the Bundle   *
  *                      API can be left behind after a          *
  *                      successful deploy. This can lead to the *
  *                      filesystem filling up.                  *
  ****************************************************************
  The bundle zip files are uploaded by the Bundle Deploy API
  using:
   javax.servlet.http.HttpServletRequest.getParts()
  
  The parts should be removed automatically by the next Java
  Garbage Collection but can be left behind if the finalize()
  method does not run or if the WUI is recycled before the Garbage
  Collection runs.
  If this happens, then after some time the USS filesystem where
  the bundle deploy temp files are stored can fill up and no more
  deployments can be performed.
  

Problem conclusion

• Change CICS code to delete the temporary zip files immediately
  after the bundle deploy completes.
