IJ44656: CICS EXPLORER IMPLIES ACTIONS TAKE LONGER THEN REALITY

APAR status

• Closed as program error.

Error description

• CICS region ended up with a significant number of tasks waiting
  on storage in the ECDSA storage pool so using CICS explorer,
  selected 22 of these tasks and force purged them.
  
  On the Explorer confirmation screen clicked "OK" ten seconds
  in and the execution completed around thirty five seconds in
  suggesting the whole action took around twenty five seconds.
  
  However, I started with six hundred tasks in the Explorer Tasks
  view so expected to end up with five hundred and seventy eight
  once the selected tasks were purged. This seems to be the case
  fifteen seconds in, five seconds after "OK" is clicked but
  Explorer continues to imply it is still purging tasks for
  another twenty seconds.
  
  Looking at MSGUSR, the purges started at 12:51:47 and completed
  at 12:51:52 - also a five second interval.
  
  Looking at Explorer service data (trace) doing a find for CICS
  task 12345 shows it being purged at 17:51:42 (12:51:42 local)
  2021/08/24 17:51:42.114 BST [1] > com.ibm.cics.core.ui.adapters
  .ActionFilterAdapterFactory.testAttribute()[IActionFilter[cicsOb
  com.ibm.cics.core.model.internal.Task[0012345], perform,
  PurgeTask]
  
  The last mention of this task in the Explorer trace is:
  2021/08/24 17:51:45.446 BST [455] -
  com.ibm.cics.core.model.ResourcesModel.removed() [0, com.ibm.ci
  cs.core.model.CICSObjectPrimaryKey[CICSGRP1/CICSRGN1/[0012345]],
  re.model.CICSObjectPrimaryKey[CICSGRP1/CICSRGN1/[0012345]]]
  

Local fix

• n/a
  

Problem summary

• If a large number of actions are queued up within CICS Explorer,
   such as a force purge on a large number of tasks, it can take a
   significant amount of time to resolve.  The reason for this is
   that every completed action causes a refresh of the visual
   resource table to take place, resulting in a delay for the
   operation to be completed.
  

Problem conclusion

• CICS Explorer has been updated so that the visual resource table
   is refreshed periodically to reflect progress rather than after
   every action.
  .
  This fix will be made available in Version 5.5.30 (33.0.4) of
  the CICS Explorer.
