# Configuring Cache Coordination Change Propagation at the Descriptor Level

Previous

Next

If you plan to use a coordinated cache (see "Understanding Cache Coordination"), you can configure how, and under what conditions, a coordinated cache propagates changes for a given descriptor.

Table: Descriptor Support for Identity Map summarizes which descriptors support cache isolation configuration.

Descriptor Support for Cache Coordination Change Propagation Configuration

Descriptor | Using TopLink Workbench | Using Java
--- | --- | ---
Relational DescriptorsFoot 1 |  |
Object-Relational Descriptors |  |
EIS DescriptorsFoot 2 |  |
XML Descriptors |  |

Footnote 1 Relational class descriptors only (see "Relational Class Descriptors").

Footnote 2 EIS root descriptors only (see "EIS Root Descriptors").

This configuration overrides the default cache coordination change propagation configuration defined at the project level (see "Configuring Cache Coordination Change Propagation at the Project Level").

To complete your coordinated cache configuration, see Configuring a Coordinated Cache.

Note: If you configure a descriptor as isolated (see "Configuring Cache Isolation at the Descriptor Level"), it cannot participate in a coordinated cache.
