WORKQUE

Description

May be used to limit the I/O operations queue for applications which are not visible.

This parameter is applicable to the SYSTEM control statement (see SYSTEM statement).

Format

WORKQUE workque-limit

Default: WORKQUE 20

Usage

IBM Session Manager displays output at a terminal from one application at any one time. For each of the other active applications on a Menu screen, it can store up to 48 I/O operations, both reads and writes, in a wraparound queue.

When a user returns to a system which has many outstanding I/O operations on the queue, IBM Session Manager executes them all very rapidly one after the other to bring the display 'up to date'. For example, if there are many output screens stored in the I/O operations queue owing to a timer updated system left running, the user will see each screen flash past as IBM Session Manager 'catches up'. On remote terminals, this could take some time.

If this situation proves inconvenient or disconcerting to users then, to limit the I/O operations queue for applications which are not visible, specify a suitable value for workque-limit (the allowed range is 4-48).

Note: The WORKQUE parameter is not applicable to SHARESESS YES users.
