Group,

We had an issue the other day when an stc was cancelled. After the job was
down mvs issued a dump in regards to a timer task. I called the vendor
and they said at termination time they check the type of termination when
performing cleanup. According to the vendor they don't cleanup timer tasks
etc. if you cancel their job. Tomorrow we will be having a meeting about a
vendors responsibility when we cancel their job. There is a camp here
that believes that if you cancel a subsystem that you should suffer no ill fate.
After talking to the vendor they report that cancelling a subsystem
can cause subsystem corruption. Because we belive that no ill fate should come
our way when we enter CANCEL a STOP command was never attempted. In
this case the stc was an mvs monitor that runs as a subsystem.
My questions: Is cancel dangerous? Should a vendor be responsible for an
abend if their subsystem is cancelled?
