    The startup parameter STEPLIB=Y (or STEP=Y) forces IDMS to load modules RHDCCKUR and RHDCTCKR from the STEPLIB instead of the CDMSLIB.

    There are two situations where you need to specify STEPLIB=Y:

    [list]
    [*]z/OS is running with AllowUserKeyCSA(NO)
    [*]#SVCOPTS specifies AUTHREQ=YES
    [list]

    In these situations IDMS needs to run in an alternate protect key and these modules need to be loaded from an APF authorized STEPLIB.
