With Top Secret, the MODE is not a real resource class like e.g. OTRAN is. But, it works in the same way. You have to give ownership for all MODEs,
i.e. add them to an owner and then permit them to an ACID.
Usually, in most shops during Top secret installation the modes are added to the MSCA. The modes are: DORM, WARN, IMPL, FAIL.
TSS WHOO MODE(*) will shows who the owner is.
To remove a MODE, you have to REVOKE it, because it is granted with the TSS PERMIT command. For example:
TSS REV(acid#) MODE(WARN) FACILITY(facility_name)
TSS REV(acid#) MODE(FAIL)
