VMDEBUG—Internal Debugging

Valid on z/VM.

Use the VMDEBUG control option to enable CA Top Secret VM internal debugging options at the request of CA Technical Support.

Note: Use the default setting of this option is strongly recommended for normal operation of the product. Specification of anything but the default, except for the purpose of problem determination by CA Technical Support personnel, may result in integrity exposures or reduce the serviceability of the product.

Use the VMDEBUG option is protected by the operator accountability feature. CA Top Secret prompts the person entering the command for the proper ACID/password combination before processing the option. CA Top Secret also creates an audit trail identifying the ACID under which the VMDEBUG specification was made.

This control option uses the Parameter File and MODIFY entry method.

This control option has the following format:

VMDEBUG([NONE]) [option(1)[,option(2)...,option(n)]]
NONE

(Default) Resets all VMDEBUG options to their inactive (unspecified) state. This may not be specified with any other options.
