Using the Common Storage Summary panel
The Common Storage Summary panel, shown in the following figure, displays the total amount of common storage that is currently in use (that is, storage for which a GETMAIN has been issued without a subsequent FREEMAIN).
Common storage is divided into CSA (common service area) and SQA (system queue area) above and below the 16-MB line.

Each unique job name/ASID combination to which storage is attributed is represented by a row on the screen. The screen is initially sorted in descending order by the Total allocated storage column. An asterisk (*) appears above that column.
The following table shows the tasks you can perform from the Common Storage Summary panel.
To perform this action | Type this command | For more information, see |
|---|---|---|
Find the summary line for a job name | F name where name is the job name that you want to find | not applicable |
Order (sort) on output column | O name where name is the output column that you want to order | |
Graph common storage areas allocated by individual address spaces | G | |
Summarize the status of the COMMON STORAGE MONITOR data collector | STAT (Only used when CSMON collects the data.) | |
Display detail allocation data | DETAIL (D) or S (line command) | |
Summarize common storage usage | OVER |
The Common Storage Summary panel contains the following output fields:
Field | Description |
|---|---|
CSA | size of the Common Service Area (CSA) and the percentage currently allocated |
ECSA | size of the Extended Common Service Area (ECSA) and the percentage currently allocated |
SQA | size of the System Queue Area (SQA) and the percentage currently allocated |
ESQA | size of the Extended System Queue Area (ESQA) and the percentage currently allocated The percentage allocated does not include fragmented available storage. The OVER command provides fragmentation information. |
Name | name of the address space (job, TSO user ID, and so on) to which ownership of the storage is attributed When IBM VSM tracking data is used, this is the name assigned according to the OWNER parameter on the GETMAIN or STORAGE macro. |
X | column where an asterisk (*) indicates that the storage is still allocated but the job that allocated the storage has been terminated |
ASID | address space identifier (in decimals) of the address space that was active when the common storage area was acquired |
Total | total amount of common storage allocated by the address space |
% | percentage of total allocated common storage used by the address space |
