How Library Cache is Maintained

The library cache basically maintains itself.

When a read request is received for a member, the library cache is reviewed to determine whether it currently contains the member.
- If the member is found in the cache, its contents are returned from the cache.
- If the member is not found in the cache, the member is read from the data set and stored into the cache.
The library cache is emptied each time the CA SYSVIEW Main Services Address Space is started.
