Steps for enabling and disabling PKA callable services and Dynamic CKDS/PKDS Access

Note: The PKA callable services control may not be active on your system. When the control is not active, all steps referring to the control can be ignored.

It is recommended that the CKDS and PKDS dynamic services be disabled during the master key change. This is not necessary when using the coordinated change master key procedure.

When you enter or change the RSA-MK, you must first disable the PKA callable services control. This requirement applies only to the RSA-MK. You do not need to disable PKA callable services control in order to enter or change the ECC-MK.

  1. Access the administrative control functions by choosing option 4, ADMINCNTL, on the ICSF Primary Menu panel. The CSFACF00 — Administrative Control Functions panel appears.
  2. Enter the appropriate character and press ENTER.
    • To enable the dynamic CKDS update services control, enter an ‘E’ before the Dynamic CKDS Access function.
    • To disable the dynamic CKDS update services control, enter a ‘D’ before the Dynamic CKDS Access function.
    • To enable the PKA callable services control, enter an 'E' before the PKA Callable Services function.
    • To disable the PKA callable services control, enter a 'D' before the PKA Callable Services function.
    • To enable the dynamic PKDS update services control, enter an ‘E’ before the Dynamic PKDS Access function.
    • To disable the dynamic PKDS update services control, enter a ‘D’ before the Dynamic PKDS Access function.

You can use a utility program to reencipher the CKDSs and change the master key instead of using the panels. See Symmetric Master Keys and the CKDS, for instructions on how to use the utility program to reencipher a disk copy of a CKDS and to change a master key.
