WQS_PERSIST_SHMEM

WIS and WQS Process Configuration

Summary

This attribute defines how often (in seconds) the contents of the WQS/WIS shared memory are written to the wqs_index table in the database.

Applies To

This attribute can be set for the WQS process (only).

Permissible Values

The attribute value must be an integer in the range 1 to 3600.

Default Value

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

Machine ID	Process	Instance	Value
0	WQS	0	300

Notes

When the WIS process starts up, it uses the total_items column in the wqs_index table to determine the number of work items in each work queue. It compares this value to the WIS_CACHE_THRESHOLD value to determine whether to cache the work queue.

If TIBCO iProcess Engine is started, cases are loaded into a work queue, then the system is shut down again within the WQS_PERSIST_SHMEM value, the item counts in the wqs_index table will not match the actual item counts.

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