Sending a transaction to an MSC system outside of an IMSplex

To send an APPC or OTMA transaction from an IMSplex to a remote IMS system outside of the IMSplex by using an MSC link:

Procedure

  1. Enable MSC in all IMS systems in the IMSplex by defining at least one MSC link in each IMS system in the IMSplex. This MSC link can be either a functional link to a remote IMS system outside of the IMSplex or, if none exists, it can be a non-functional MSC link.
  2. Define an MSC link between the IMSplex and the remote IMS system.
  3. In any IMS system in the IMSplex, define a remote MSC transaction and assign it to an MSC link by specifying remote and local SYSIDs in the SYSID keyword of the TRANSACT macro.
    The remote SYSID must match the SYSID of the remote MSC IMS system. The local SYSID must match the SYSID of the IMS system that is connected to the APPC or OTMA client.
  4. In the remote MSC IMS system, define a local transaction to process the APPC or OTMA transaction message.
