Object Broker Service
The Object Broker Service hosts four different servers, all of you which you can load balance:
Relex.BusinessObjects.Service
Supports the Relex.BusinessObjects.IService contract
Responsible for the bulk of read/write operations to the database
Relex.Windchill.WindchillIntegrationServer
Supports the Relex.Windchill.IWindchillIntegrationServer contract
Responsible for simple (as opposed to long-running and/or repeated) communication with the Application Server configured in Windchill Risk and Reliability Administrator
Relex.Security.SecurityServer
Supports the Relex.Security.IAccessManager contract
Supports the Relex.Security.IUserGroupManager contract
Responsible for authentication, permissions checking, and user and group management
The preceding information is available in the server-side configuration file that gets installed with Windchill Risk and Reliability: RiskandReliability.Service.ObjectBroker.exe. You can load balance this entire set of servers all together. You do not need to separate these servers when load balancing the Object Broker Service.
