Reinstating an online updater

Given the following initial and target configurations, use this scenario to restore the initial configuration.

  • Initial configuration
    • dbx is authorized for read-only access to an online IMS system (IMSA).
    • A batch IMS system has been terminated.
  • Target configuration
    • dbx is registered at share level 1.
    • dbx is authorized for update access to IMSA.

Follow these steps to reinstate an online updater:

Procedure

  1. Prevent other IMS systems from obtaining access to dbx with the following command: CHANGE.DB DBD (dbx) NOAUTH
    When you force IMSA to release its authorization on dbx, another IMS system could obtain authorization to process it. The DBRC CHANGE.DB command with the NOAUTH keyword indicates (in the database record in the RECON data set) that the database is unavailable for processing.
  2. Terminate IMSB.
  3. Suspend IMSA's activity on dbx, close dbx, and release IMSA's authorization with one of the following commands:
    • /DBRECOVERY DB dbx NOFEOV
    • UPDATE DB STOP(ACCESS) OPTION(FEOV)
  4. Allow update processing for IMSA with one of the following commands:
    • /START DB dbx ACCESS=UP
    • UPDATE DB START(ACCESS)
  5. Allow access or update in IMSA with the following command: CHANGE.DB DB dbx AUTH

The initial configuration of the scenario is described in Scheduling a batch updater.
