Before you begin
A Coherence cache configuration file defines the caches and services that are used by an application. Typically, a cache configuration file is included in a GAR module. A GAR is deployed to all managed Coherence servers in the data tier and can also be deployed as part of an EAR to the application tier. The GAR ensures that the cache configuration is available on every Oracle Coherence cluster member. However, there are use cases that require a different cache configuration file to be used on specific managed Coherence servers. For example, a proxy tier requires access to all artifacts in the GAR but needs a different cache configuration file that defines the proxy services to start..
You can use the Administration Console to define a cluster cache
configuration. A cache configuration file can be associated with
WebLogic clusters or Managed Coherence Servers at runtime. In this case,
the cache configuration overrides the cache configuration file that is
included in a GAR. You can also omit the cache configuration file from a
GAR file and assign it at runtime. To override a cache configuration
file at runtime, the cache configuration file must be bound to a JNDI
name. The JNDI name is defined using the
override-property attribute of the
<cache-configuration-ref> element. The element is
located in the
coherence-application.xml file that is
packaged in a GAR file. For details on the
coherence-application.xml file, see Oracle Fusion Middleware Developing
Oracle Coherence Applications for Oracle WebLogic Server. For
more information on importing a cache configuration file, see Using a Cluster Cache

If you do not select this option, the cache configuration file is loaded directly from the specified location when the server is started.
The cluster cache configuration is listed from the Configuration: Cache Configurations page of the Coherence cluster settings console page.
