Commands and Responses
ZTMF-MAP-Alter-AuditDump
is an extensible structured token specifying the attributes of the audit dump
process to be changed. This token is required; only one occurrence is allowed.
This token contains the following fields:
ZCopies
for dumps to tape, specifies the number of copies made of each audit dump.
The following values are valid:

If the value of ZCopies is ZTMF-VAL-ResetWord, the number of copies
made is reset to 1.

If the value of ZSeries is ZSPI-VAL-False, the value of ZCopies can be 1 or
2.

If the value of ZSeries is ZSPI-VAL-True, the value of ZCopies can be 1, 2,
or 3.
Specifying multiple copies is recommended to enable file recovery if one of the
copies cannot be read.
ZSeriesCopies
for dumps to tape, specifies whether multiple copies of audit dumps are made
in parallel or in series. The following values are valid:
ZTMF-VAL-True
ZTMF-VAL-False
ZVerifyTape
for dumps to tape, specifies whether tape verification is performed after a tape
is written. The following values are valid:
ZTMF-VAL-True
Tapes are verified. After each tape volume is written, it is rewound, read
completely, and finally rewound and unloaded. The tape-record
checksums, tape-record sequence numbers, and tape format are verified.
The checks are the same as those made during file recovery; however,
tape verification does not include comparing the tape data to the audit trail
files on disk.
If tape verification fails, an error is returned, the audit dump terminates,
and the audit dump copy is marked invalid in the catalog. Tape verification
approximately doubles the time needed for an audit dump.
ZTMF-VAL-False
Tapes are not verified.
