Items to Consider

Deploy Substation ES address spaces for an ACTIVE-ACTIVE setup and use a CICS TOR-AOR setup or CICSPlex to handle CICS dynamic routing.

Both Substation ES address spaces process messages. This configuration is an ACTIVE-ACTIVE setup. Substation ES does not support an ACTIVE-PASSIVE setup, where one Substation ES does all the processing and the other assumes control in the event of an outage.

Currently, Substation ES does not handle CICS dynamic routing. Even though recipes are dedicated to a BES, the ability to override the BES designation by specifying properties or information on the input message is possible. With a CICS TOR-AOR setup or CICSPlex, you can dynamically route CICS transactions and programs through Substation ES.
