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]]]

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. .
