Use WebSphere eXtreme Scale for SIP session management

Use WebSphere eXtreme Scale as a Session Initiation Protocol (SIP) replication mechanism as a reliable alternative to the data replication service (DRS) for SIP session replication.


SIP session management configuration

To use WebSphere eXtreme Scale as the SIP replication mechanism, set the com.ibm.sip.ha.replicator.type custom property. In the administrative console, select Application servers > my_application_server > SIP container > Custom properties for each server to add the custom property. Type com.ibm.sip.ha.replicator.type for the Name and OBJECTGRID for the Value.

Use the following properties to customize the behavior of the ObjectGrid that is used to store SIP sessions. In the administrative console, click Application servers > my_application_server > SIP container > Custom properties for each server to add the custom property. Type the Name and Value. Each server must have the same properties set to function properly.
