Configuring the Engine for FTGroup Persistence Mode

In the managed fault tolerance ftgroup mode, only one AppNode runs the application, and the other AppNodes are standing by.

When the bw.engine.ftgroup.lbmode property is set to true in the config.ini file at the AppSpace level, all processes having Activation mode set as Multiple AppNodes in TIBCO Business Studio™, run on all bwengines in the group.
Note: By default, bw.engine.ftgroup.lbmode is set to false.

When you want to elect an AppNode as a leader AppNode, then set the bw.engine.use.weighted.node property to true at an AppSpace level. For more information about the bw.engine.use.weighted.node property, see BW Engine ftgroup Properties.

Note: By default, the bw.engine.use.weighted.node property is set to false.

The ftgroup mode does not support checkpointing. When configured for the ftgroup persistence mode, the bwengine requires the group provider, such as TIBCO Enterprise Message Service (EMS) or TIBCO FTL®, to be configured.

For instructions about setting TIBCO EMS or TIBCO FTL as the group provider technology for the engine, see the following topics:
