Dumping Enscribe Alternate-Key Files and
Partitioned Files
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.
The following example shows a DUMP FILES command that specifies a file set list and
a NOT file set list to skip some $SYSTEM subvolumes:
28> TMFCOM
TMF 1> DUMP FILES $SYSTEM.*.*, BLOCKSIZE 28 &
>>>NOT ($SYSTEM.SYSTEM.*, $SYSTEM.ZTMFAT.*, $SYSTEM.SYS01.*)
The next example shows a DUMP FILES command that specifies disk volumes as the
dump media:
29> TMFCOM
TMF 1> DUMP FILES $DATA.*.*, DISKMEDIA ($AUD01, $AUDX.DF)
The following DUMP FILES command dumps the files identified by the patterns listed
in the <file-name> file named $DENVER.HIGH.GROUPN:
30> TMFCOM
TMF 1> DUMP FILES <$DENVER.HIGH.GROUPN>
Dumping Enscribe Alternate-Key Files and Partitioned Files
TMF dumps only the objects you specify in the DUMP FILES command: it does not
automatically dump dependent objects, such as alternate-key files or secondary
partitions. Explicitly dumping alternate-key files and secondary partitions is normally
the most efficient method if you must later perform file recovery of these audited files.
Another method for recovering alternate-key files is to omit them from the online dump
and then to rebuild the key files with the FUP LOADALTFILE command after the
primary file is recovered.
Note. After each online dump, use the INFO DUMPS command to get a detailed report of
dumps currently recorded in the TMF catalog. Save your reports in a disk file stored in a safe
location, sorted by date. You can also manually track online dump entries by using the forms
provided in Appendix A, Dump Tracking Forms
. As an especially valuable aid, you can
generate a command file that contains ADD DUMPS commands for re-adding to the TMF
catalog all entries for dumps with a specified serial number. To create this command file, enter
the INFO DUMPS command in this format:
INFO / OUT filename / DUMPS, OBEYFORM, SERIAL serial-number
In addition, keep a backup copy of the $SYSTEM.ZTMFCONF subvolume, which contains all
TMF configuration information. This information is critical if entries in the TMF catalog are
accidentally deleted or damaged and need to be reentered into the catalog.
