Overview of Space Monitor
The Space Monitor utility assists the users to forecast potential space utilization problems of IMS full-function database data sets that HD Pointer Checker supports, and OS data sets (including VSAM data sets).
Note: The term OS data sets used in this user's guide includes VSAM data sets. It generally means non-IMS data sets in this guide.
Frequent (usually daily) use of this utility helps you prevent
system abend conditions due to:
- More space is needed, but none is available
- More space is needed, but the limit of the extent has been reached
When the Space Monitor utility detects these conditions, it notifies such conditions by return codes. Optionally, it sends a notification message to TSO user IDs.
