Parameter descriptions

 

(psid-number)

Identifier of the page set. This is required.

EXPAND

Controls how the queue manager should expand a page set when it becomes nearly full, and further pages are required in it.

USER

The secondary extent size that was specified when the page set was defined is used. If no secondary extent size was specified, or if it was specified as zero, then no dynamic page set expansion can take place.

At restart, if a previously used page set has been replaced with a data set that is smaller, it is expanded until it reaches the size of the previously used data set. Only one extent is required to reach this size.

SYSTEM

A secondary extent size that is approximately 10 per cent of the current size of the page set is used. It may be rounded up depending on the characteristics of the DASD.

The secondary extent size that was specified when the page set was defined is ignored; dynamic expansion can occur if it was zero or not specified.

NONE

No further page set expansion is to take place.
