MSTORAGE service
The MSTORAGE (MST) service maps virtual storage areas above and below the 16 MB line, including location, length, and percentage used, when applicable.
Areas common to all address spaces and private area locations specific to the specified address space are displayed, when available.
The private area above and below the 16 MB line is divided into three sections:
- LSQA/SWA—allocated from the top of the private area down
- User-committed private area—allocated from the bottom up
- Uncommitted area—allocated between the LSQA/SWA and user-committed private area
The current utilization within the LSQA/SWA and committed private area is displayed. LSQA/SWA can expand into the uncommitted area as needed. Committed private area can expand into the uncommitted private area to the user limit value.
Syntax
The parameter is defined as follows:
Parameter | Description |
