PrerequisiteBefore starting, open port 64432 and keep the port open as long as the mainframe is connected.
Adding or removing mainframe connectivity typically takes 3 to 5 minutes, depending on your configuration.
  1. Stop the database.
    # tpareset –x –y stop for mainframe connectivity
  2. Verify the database is in a DOWN/HARDSTOP state.
    # pdestate -a
    PDE state: DOWN/HARDSTOP
    Putting the database in this state may take several minutes.
  3. Do one of the following to run the command.
    Option Action
    To add connectivity
    1. Run tdc-mainframe add with arguments.
    where:
    • -c followed by the number of PEs to add
    • -y used in conjunction with -c, bypasses user prompt and proceeds running the command automatically
    • -h to display help information
    To remove connectivity
    1. Run tdc-mainframe delete without arguments.

    PEs and nodes are automatically removed when this command is run.

    • Example of adding two mainframe PEs: tdc-mainframe add -c 2
    • Example of adding one mainframe PE: tdc-mainframe add -c 1
    • The database restarts multiple times when tdc-mainframe is running.
  4. At the prompt, check the database status to make sure logons are enabled.
    # pdestate -a
    PDE state is RUN/STARTED.
    DBS state is 4: Logons are enabled - Users are logged on
  5. If you remove mainframe connectivity, close port 64432.
