Configuring a Multicast Port

The multicast port is the port on which multicast messages are received. Members of a multicast group (see "Configuring a Multicast Group Address") rely on messages broadcast to their multicast group address to communicate with one another.

Table 91-6 summarizes which coordinated caches support multicast port configuration.

Table 91-6 Coordinated Cache Support for Multicast Port Configuration

Coordinated Cache	Using TopLink Workbench	Using Java
JMS Coordinated Cache
RMI Coordinated Cache
CORBA Coordinated Cache
Custom Coordinated Cache

Note: Ensure your host and network are configured to support multicast operation before configuring this option

Using TopLink Workbench

To specify the multicast port, use this procedure:

1. Select a session or session broker in the Navigator. Its properties appear in the Editor.

2. Click the Cache Coordination tab. The Cache Coordination tab appears.

3. Ensure the Enable Cache Coordination option is selected, then select the appropriate coordinated cache Type (see Table 91-6). The cache coordination options appear on the tab.
