Purpose

Lists information and statistics about one or more established session pools.

Syntax



The DI and DIS abbreviations are deprecated.

where:

poolid
Id of pool whose information is to be displayed.
ALL
Request that information about all pools be displayed.

Usage Notes

If an error occurs during START POOL processing (because creation of further pool sessions will cause the database or installation-defined maximum session capacity (MAXSESS) to be exceeded), you can use the DISPLAY POOL command to determine how many sessions were successfully added to the pool before the error prevented further processing. Later, if session demand is reduced, you can use the MODIFY SESSIONS command to acquire the desired number of sessions for the pool.

Example: DISPLAY POOL

D POOL ID ACTR04
D POOL ALL

Completion Message

The completion message to the DISPLAY POOL command consists of a header line, followed by one line of statistics per pool, as follows:
