Coordinated Cache Change Propagation Options

Use the following information to enter data in the Coordination field:

Coordination Option | Description | When to Use
--- | --- | ---
None | For both existing and new instances, do not propagate a change notification. | Infrequently read or changed objects.

Synchronize Changes

For an existing instance, propagate a change notification that contains each changed attribute.

For a new instance, propagate an object creation (along with all the new instance's attributes) only if the new instance is related to other existing objects that are also configured with this change propagation option.

Frequently read or changed objects that contain few attributes or in cases where only a few attributes are frequently changed.

Objects that have many or complex relationships.

Synchronize Changes and New Objects

For an existing instance, propagate a change notification that contains each changed attribute.

For a new instance, propagate an object creation (along with all the new instance's attributes).

Frequently read or changed objects that contain few attributes or in cases where only a few attributes are frequently changed.

Objects that have few or simple relationships.

Invalidate Changed Objects

For an existing instance, propagate an object invalidation that marks the object as invalid in all other sessions. This tells other sessions that they must update their cache from the data source the next time this object is read.

For a new instance, no change notification is propagated.

Frequently read or changed objects that contain many attributes in cases where many of the attributes are frequently changed.
