PMDC is a third party performance monitoring tool for IDMS.
An IDMS CV with PMDC installed may encounter a 3951 abend at shutdown.
During shutdown, the PMDC task can stay active preventing the CV from shutting down for a long enough period of time to cause a 3951 abend.
This can be due to the values set for the IDMS TICKER interval and the PMDC TICK parameter. As long as the multiplication of the two intervals is lower than 60, the 3951 abend should not occur. Anything higher will risk running into a 3951 abend.
Release : All supported releases.
