# Configuring a Service Channel

The service channel is the name of the TopLink coordinated cache channel to which sessions subscribe in order to participate in the same coordinated cache. Such sessions use the service channel to exchange messages with each other. Messages sent on other service channels will not be exchanged with this coordinated cache.

Table 91-4 summarizes which coordinated caches support service channel configuration.
