DUMP FILES Command Examples
•
The TAPEMEDIA option specifies which tapes to use when dumping the audited
files. A TMF scratch tape is always acceptable for an online dump; if one is
already mounted, or mounted instead of the specified tape, it will be used.
•
The DISKMEDIA option specifies where the dumps should be recorded. At least
one volume must be specified, with a maximum of 16 volumes. If a list of volumes
is given, the dump process tries to use the first disk. If this disk cannot be
accessed or is out of space, the next disk is tried, and so forth. Disk media is
specified as follows:
DISKMEDIA disk-volume-list
A disk volume can be specified in the following forms:
\remote-node.$volume.prefix
\local-node.$volume.prefix
\local-node.$volume
$volume
$volume.prefix
The default prefix is ZT. You can use this default or define another two-character
prefix, which you might want to do to segregate different applications’ dumps from
one another.
See the TMF Reference Manual for a list of all DUMP FILES command options and
detailed instructions on using the DUMP FILES command.
DUMP FILES Command Examples
The examples that follow show some typical methods for using the DUMP FILES
command to produce online dumps. When an online dump is complete, the dump
process generates a report. More examples appear in the TMF Reference Manual.
The following example shows a DUMP FILES command that specifies the file set list
with the wild card (*) syntax:
26> TMFCOM
TMF 1> DUMP FILES $DATA.*.*
All files on the $DATA volume will be dumped to tape, which is the default. Dumping
an entire volume ensures that all audited files get dumped.
The following example shows a DUMP FILES command that also uses the wild card:
27> TMFCOM
TMF 1> DUMP FILES *.DATABASE.*
All of the files in a partitioned database will be dumped to tape.
Caution. If you specify a remote dump location, you must use a different prefix from ZT to
prevent a remote dump from overwriting a local dump in the default location.
