Object Management and Fault Tolerance Scenarios
Fault tolerance and object management options work in various deployment scenarios to maintain data integrity.
Note: TIBCO BusinessEvents Express: Content relating to Cache OM is not relevant to TIBCO BusinessEvents Express edition.
The tables in this section help you understand how fault tolerance and object management options work and explain what is possible in each type of object management given the following conditions:
- Processing Units (PUs)
- One or multiple PUs, where a PU is a TIBCO BusinessEvents server running in one JVM.
- Agents
- One or multiple inference agents running in a PU. Each inference agent is configured by an agent class in the CDD. An inference agent has one or more Rete networks.
When implementing a recovery strategy you must take care to maintain the integrity of stateful objects. Concepts and scorecards are stateful objects and must maintain state across inference agents.
- Cache OM with Memory Only Mode on All Objects and Fault Tolerance
In Memory object management does not support fault tolerance. - Cache OM and Fault Tolerance
Fault tolerance of the engine process refers only to inference agents.
