TSTC—Grid Task State Change
When a grid task is added, started, paused, canceled, or completed,
this message is issued to audit the change in task state.
This message is used to determine what tasks have been added, run,
and completed, and the result of the completion.
The Task Status serves to indicate why the task is in the current state. If
a task ends abnormally (is aborted or fails) and requires a rollback, the
reason is retained in the task status (TCTS). The status of the rollback
itself is noted within the state (TSTS). The sequence of messages
would indicate either:
• ROLA > HIST if the rollback is successful, or
• ROLA > ROLF > HIST if the rollback failed.
