VPE Purge Utility

Various session storage is only deleted after a timeout or disconnection if the VPE Purge Invocation code has been invoked.

If the VPE Purge Invocation Code (VPUR) is not executed after a timeout or disconnection, you can expect the following to remain:

User session Temporary Storage records allocated by CA IPC, CA Datadictionary, and CA Ideal
EDSA acquired for the updateable copy of the application program
Use counts and enqueues performed on VLS entities
Storage allocated by CA Datadictionary for each terminal accessing CA Datadictionary

If this happens it is because VPE has not been returned control, which allows it to clean up the session. Without invoking the VPE Purge Invocation code, this data can only be released if another VPE-based transaction uses the same terminal or CICS is recycled.
