Interpreting storage manager statistics

Dynamic program compression releases programs which are not being used progressively as storage becomes shorter. However, short-on-storage conditions can still occur and are reported as "Times went short on storage". If this value is not zero you might consider increasing the size of the dynamic storage area. Otherwise you should consider the use of MXT and transaction classes to constrain your system’s virtual storage.

Storage manager requests "Times request suspended", and "Times cushion released", indicate that storage stress situations have occurred, some of which may not have produced a short-on-storage condition. For example, a GETMAIN request may cause the storage cushion to be released. However, loader can compress some programs, obtain the cushion storage, and avoid the short-on-storage condition.

Note:
In the task subpools section, the "Current elem stg" is the number of bytes actually used while "Current page stg" is the number of pages containing one or more of these bytes.
