LTM for MVS processing flow

LTM for MVS processes as follows:

  1. Logs in to the primary Replication Server.

  2. Sends a connect source command to identify the session as a log transfer source and to specify the database log to be transferred.

  3. Obtains the maintenance user ID from Replication Server. LTM for MVS uses the Replication Server maintenance user ID to filter operations executed by the maintenance user.

  4. Requests the origin queue ID from Replication Server. The origin queue ID contains the LTM Locator value.

    Replication Extract (LTMEXT) uses the LTM Locator value to determine the point in the log at which LTM for MVS should begin transferring transaction operation records. Replication Server successfully received all log records up to this location.

  5. Receives transaction operations from Replication Extract following the point in the log indicated by the LTM Locator value and formats them into LTL commands.
