Nonresident tapes should not be confused with EDM controlled tapes. Nonresident tapes are simply identified, not managed. EDM controlled tapes are supported by compatible interfaces between the EDM system and CA 1.
Tape volumes which are not considered part of the installation tape library and are not controlled by CA 1 can be processed by specifying a special keyword in the DD statement that references the nonresident tape.
Standard MVS protection is maintained and the operator is required to verify that the volume being processed is actually a nonresident tape if there is a matching volume serial number in the TMC (during output processing). This verification process helps ensure the integrity of CA 1.
The use of a nonresident tape is recorded in the Audit data set to provide a record of all nonresident processing. The keyword which allows nonresident tape processing is an expiration date of 98000, and is specified as LABEL=EXPDT=98000 or ACCODE=xCANORES in the appropriate DD statement that references the tape.
Nonresident tapes having a volume serial number outside the range of the TMC can be used as input without the nonresident specification. All nonresident output requests must contain the nonresident keyword, regardless of whether there is a corresponding Volume record in the TMC.
An exit is available which allows tapes to automatically bypass CA 1 control.
