# WIS_UNCACHE_PERIOD

WIS and WQS Process Configuration

## Summary

This attribute defines the time period (in minutes) after which the cached work queue that waits to be handled by the `WIS` process is cleared from the cache, starting from the time at which the client who last accessed this work queue logs off.

Note: This attribute only applies to the work queues that contain the number of work items less than the number you defined in the `WIS_CACHE_THESHOLD` attribute.

## Applies To

This attribute can be set for the `WIS` processes.

## Permissible Values

The attribute value must be one of the following:

Value | Meaning
n | The timeout period, where `n` is any integer value in minutes.

## Default Value

The attribute is assigned the following default value when iProcess Engine node is installed.

Machine ID | Process | Instance | Value
0 | WIS | 0 | 0

The default value means never un-cache the work queue. It performs like previous versions of TIBCO iProcess Engine that did not support this attribute.

## Notes

This attribute is used in conjunction with the `WIS_CACHE_THRESHOLD` attribute. If the cached work queue contains a number of work items that equals or exceeds the value of the `WIS_CACHE_THRESHOLD` attribute, it cannot be cleared from the cache by using the `WIS_UNCACHE_PERIOD` attribute.
