MIRROR—Maintain a Mirror Copy of the Security File

Valid on z/OS.

Use the MIRROR control option to specify whether the product maintains a mirror copy of the primary security file. Having a mirror file available allows greater flexibility for when to schedule backup processing (for example, less frequently). Additionally, the mirror file is an exact duplicate of the primary security file and provides up-to-the-minute data in the event of a sudden problem with the primary file.

This control option uses the parameter file entry method.

This control option has the following format:

MIRROR(ON|OFF)

ON

Maintains a mirror copy of the security file. The ON specification must be included in the CA Top Secret parameter file, where it takes effect at the next product startup.

OFF

Does not maintain a mirror copy of the security file. This value is the default value.
