Configuring the embedded global cache by using commands
You can customize the default global cache topology to use a specific port range and listener host, or you can turn off the default topology and specify your own execution group properties. Multiple brokers can share a cache by using a policy file.
For more information about the default global cache topology, see Data caching overview.
Use WebSphere Message Broker commands to turn off the default topology and set execution group properties explicitly (see Execution group properties).
You can also use the mqsicacheadmin command to clear data from a map. For more information, see mqsicacheadmin command.

Execution group properties
Before you can set properties explicitly for an execution group, you must set the cache policy property to none for the broker. You can set the policy by using the mqsicreatebroker, mqsichangebroker, or mqsichangeproperties command, as described in Broker properties. The execution group properties that were set most recently by the broker-level policy are retained as a starting point for customization.
To use the new properties that you set, restart the execution group.
