ODBM message routing

When you define the IMS systems in an IMSplex to ODBM, you also assign one or more alias names to each IMS system. The alias names are what the ODBM clients and ODBM use to route database access requests to the IMS systems.

If an alias name is shared by multiple IMS systems in an IMSplex, ODBM uses a round-robin algorithm to distribute incoming requests that specify the shared alias name among the sharing IMS systems.

Similarly, when incoming requests leave the alias name blank, ODBM also uses a round-robin algorithm to distribute incoming requests among all IMS systems available to ODBM in the IMSplex.
