RESTART_WIS_CACHE_THRESHOLD

WIS and WQS Process Configuration

Summary

This attribute defines the number of items that must exist in a work queue for it to be cached when the WIS process restarts or quick starts.

Applies To

This attribute can only be used when a WIS process restarts or quick starts.

Permissible Values

This attribute must be an integer in the range 0 to 500000.

Default Value

This attribute is not defined on a newly installed iProcess Engine node. In this case, the default value is:

Machine ID

WIS

0

1000

This attribute only appears in the output of the SHOW_ALL_ATTRIBUTES command if you have explicitly assigned a value to it using the SET_ATTRIBUTE command. The default setting is not displayed.

Notes

A queue is usually cached in the following two situations:

When the WIS process first handles the queue (either on startup or after a MoveSysInfo operation).
When the queue is first accessed by a client application.

This attribute is only used when the WIS process restarts or quick starts in conjunction with the WISCACHE queue attribute to control whether a queue is cached:

If the value of WISCACHE is set to YES, the WIS process caches the queue (irrespective of how many work items there are in the queue).
If WISCACHE is not created or set, the WIS process caches the queue when the number of work items in the queue equals or exceeds the value of the RESTART_WIS_CACHE_THRESHOLD attribute.

See Configuring When WIS Processes Cache Their Queues for more information.
