TIBCO iProcess® Engine 11.9.1

# FREE_WIS_SESSION

General iProcess Engine Configuration

## Summary

This attribute defines whether the WIS session, which is used to retrieve work items, should be freed up in the WIS memory or not after the lock, keep, forward, release, undo, or unlock operation.

Note: This attribute is only used for doing the lock, keep, forward, release, undo, and unlock operations.

## Applies to

This attribute should be set for the `SPO` processes.

## Permissible Values

The attribute value must be one of the following.

Value | Meaning
0 | The WIS session, which is used to retrieve work items by TIBCO iProcess Objects Server, is saved in the WIS memory after the lock, keep, forward, release, undo, or unlock operation.
1 | The WIS session, which is used to retrieve work items, is freed up in the WIS memory after the lock, keep, forward, release, undo, or unlock operation.

## Default Value

This attribute is not defined automatically when you install or upgrade iProcess Engine. The WIS session that is used to retrieve work items by TIBCO iProcess Objects Server is saved in the WIS memory by default.

## Notes

Details of how to use this attribute are as follows:

| • | If the WIS session that is used for retrieving work items is saved in the WIS memory, the TIBCO iProcess Objects Server can reuse the existing WIS session to retrieve work items. Therefore, the average time to retrieve work items is reduced. However, saving WIS sessions in the WIS memory may take up a lot of memory space.

| • | If the WIS session that is used to retrieve work items is freed after each operation, the WIS session needs to be re-created when another operation is performed. So the average time to retrieve work items is increased. However, cleaning up the WIS session in the WIS memory may save a lot of memory space.
