IV72844: -XSHARECLASSES:DESTROYALL DOES NOT REMOVE CONTROL FILES OF A NON-PERSISTENT CACHE IF THE ASSOCIATED SHARED MEMORY IS NO LONGER P

APAR status

• Closed as program error.

Error description

• Error Message: N/A
  .
  Stack Trace: N/A
  .
  

Local fix

• Manually remove the control files using 'rm' command, or if the
  name of shared class cache is known, then use
  -Xshareclasses:name=<cache_name>,destroy,nonpersistent command
  to remove the control files for the specified non-persistent
  cache. Take care to manually remove only the intended control
  files, as using 'rm' to remove control files of a valid shared
  class cache will abandon the associated shared memory, which
  will then require additional manual steps to remove. For more
  details on handling of control files, please refer to the
  section titled \"Nonpersistent shared cache cleanup\" in
  \"Diagnostic guide for IBM SDK, Java Technology Edition\"
  

Problem summary

• -Xshareclasses:destroyAll fails to remove the control files of
  the non-persistent shared class cache for which the
  corresponding shared memory is no longer present in the system.
  

Problem conclusion

• The JVM has been updated to remove the control files even when
  the shared memory associated with the shared class cache is no
  longer present in the system.
