OTMA Super Members

You can use Substation ES with OTMA super members as targets for regular messages, triggers and requests/replies.

Consider the following points when configuring and using Substation ES with OTMA super members:

Multiple Substation ES IMS interfaces can point to the same Tpipes under a super member. They can be in the same Substation ES instance or separate ones.
IMS will process messages sent from an ESB to any Substation ES that references the TPIPE-DEFAULT plus the super member.
To support conversational messages, either use the DFSYDRUn and DFSYPRXn user exits to handle TPIPE-PREFIX=, or define TPIPE-PREFIX= tpipes from 001 to 255 with the SMEM= parameter.

Note: Note the following points regarding triggers and requests/replies:

Because of IMS design, only one interface at a time processes triggers and requests/replies; the other interfaces remain idle.
When an interface terminates, whether planned or unplanned, IMS begins sending traffic to the next interface that becomes active.
If more than two interfaces are active, IMS will move traffic to the interfaces in the order in which they became active.
When the first interface becomes active again, it takes its place in line behind the now-active interface.
