SHOW WORKING_SET

On Alpha and I64 systems, displays the working set limit, quota, and extent (in pagelets and CPU-specific pages) assigned to the current process. This information also can be output in bytes.
On VAX, displays the working set limit, quota, and extent (in pages) assigned to the current process.

Format

SHOW WORKING_SET

Parameters

None.

Qualifier

/OUTPUT[=filespec]

/NOOUTPUT
Controls where the output of the command is sent. If you do not enter the qualifier, or if you enter the /OUTPUT qualifier without a file specification, the output is sent to the current process default output stream or device, identified by the logical name SYS$OUTPUT.
If you enter the /OUTPUT qualifier with a partial file specification (for example, specifying only a directory), SHOW is the default file name and .LIS the default file type. The asterisk (*) and the percent sign (%) wildcard characters are not allowed in the file specification.
If you enter the /NOOUTPUT qualifier, output is suppressed.

Examples

$ SHOW WORKING_SET
Working Set (pagelets)  /Limit= 2000  /Quota= 4000 /Extent= 6000
Adjustment enabled  Authorized Quota= 4000  Authorized Extent= 6000

Working Set (8Kb pages) /Limit= 125   /Quota= 250  /Extent= 375
                    Authorized Quota= 250  Authorized Extent= 375

This example shows the SHOW WORKING_SET command on Alpha. The process has a working set limit of 2000 pagelets (125 pages) and a quota of 4000 pagelets (250 pages), and the current quota is equal to the authorized limit (4000 pagelets; 250 pages). It also shows that the current process has a working set extent of 6000 pagelets (375 pages) and that the current extent is equal to the authorized limit (6000 pagelets; 375 pages). A pagelet is 512 bytes.

$ SHOW WORKING_SET
  Working Set (pagelets)  /Limit=3632  /Quota=8192  /Extent=524288
  Adjustment enabled      Authorized Quota=8192  Authorized Extent=524288
  Working Set (8Kb pages) /Limit=227  /Quota=512  /Extent=32768
                          Authorized Quota=512  Authorized Extent=32768
$ SET PROCESS/UNITS=BYTES
$ SHOW WORKING_SET
  Working Set (bytes)     /Limit=1.77MB  /Quota=4MB  /Extent=256MB
  Adjustment enabled      Authorized Quota=4MB  Authorized Extent=256MB

This example shows the same display, first in bits and then in bytes.

#3
$ SHOW WORKING_SET Working Set /Limit= 180 /Quota= 350 /Extent=1200 Adjustment enabled Authorized Quota= 350 Authorized Extent=1200

This example shows the SHOW WORKING_SET command on VAX. The process has a working set limit of 180 pages, a quota of 350 pages, and the quota is equal to the authorized limit (350 pages). It also shows that the current process has a working set extent of 1200 and that the current extent is equal to the authorized limit (1200). Each page on a VAX is 512 bytes.
