Using the System Request Key

You can access DST by using the System Request Key only when the system is in debug mode.

About this task

Debug mode is an environment to test programs. You can select a function key and access DST during the IPL process. For details, see Perform an IPL.

From the console, perform the following steps:

Procedure

  1. Press the System Request Key.
  2. Type DST on the system request line.
    Note: Commands are case-sensitive.
  3. Sign on to DST.
    Type QSRV as the valid user ID and get the password from the customer. If the customer has changed the full DST authority user ID or password, ask the customer for the correct values. The Use Dedicated Service Tools (DST) display appears.
    Notes:
    • If prompted to change the password, be sure to provide the new (changed) password to the customer.
    • You are limited to three sign-on attempts to DST. After three unsuccessful attempts, the service tools user ID will be disabled. A user ID with a service tool security privilege must reset the ID.

    For details about the DST options, see DST options. This ends the procedure.
