Configure Object Request Brokers
Use the orb.properties file to pass the properties that are used by the ORB to modify the transport behavior of the data grid. WebSphere eXtreme Scale uses the ORB to enable communication among processes. No action is required to use the ORB provided by WXS or WAS for the WXS servers. Use tuning considerations and other ORB-related configuration tasks you might want or need to perform.
Before you begin
Restriction: You cannot have servers in a WAS environment with the same name when the servers are using the ORB to communicate with each other. You can resolve this restriction by specifying the system property...
-Dcom.ibm.websphere.orb.uniqueServerName=true...for the processes that have the same name. For example, when servers with the name server1 on each node are used as a catalog service domain, or where multiple node agents are used to form a catalog service domain.
- ORB properties file
The orb.properties file is used to pass the properties that are used by the ORB to modify the transport behavior of the data grid.
- ORB properties and file descriptor settings
Tuning considerations include ORB properties and file descriptor settings.
- Enable NIO or ChannelFramework on the ORB
WXS provides a server property to set the TransportMode property to ChannelFramework in order to enable non-blocking I/O (NIO) on the ORB.
- Use the ORB with stand-alone WXS processes
Use WXS with applications that use the ORB directly in environments that do not contain WAS or WAS ND.
- Configure a custom Object Request Broker
WXS uses the ORB to enable communication among processes. No action is required to use the ORB provided by WXS or WAS for the WXS servers. Little effort is required to use the same ORBs for the WXS clients. If instead use a "custom" ORB, the ORB supplied with the IBM SDK is a good choice, although we will need to perform some configuration, as described here. ORBs from other vendors can be used, also with configuration.
