PARTONLY
The PARTONLY option specifies whether all partitions of a partitioned file are backed up. This
option applies to both Enscribe and SQL files.
PARTONLY [ ON | OFF ]
ON
specifies that only the partitions of a file explicitly named in
backup-files
are backed up.
ON is the default if you specify PARTONLY in the BACKUP command.
OFF
specifies that if the primary partition is specified in
backup-files
, then both the primary
and secondary partitions are backed up. OFF is the same as omitting PARTONLY from the
BACKUP command.
Guidelines
•
If you specify PARTONLY ON, you cannot specify INDEXES IMPLICIT.
•
If you specify PARTONLY ON in your BACKUP command, PARTONLY ON is automatically
applied during the RESTORE operation for those files.
•
If you name the primary partition of a file in
backup-files
, PARTONLY ON specifies that
only that particular partition (in this case, the primary partition) is backed up. The secondary
partitions are not backed up unless they are explicitly named in
backup-files
.
•
If you name the primary partition of a file in
backup-files
, PARTONLY OFF specifies that
all the secondary partitions of the file are backed up. That is, if you name the primary partition
in
backup-files
, the entire partitioned file is backed up even though the secondary partitions
are not named in the
backup-files
.
•
If you name a secondary partition of a file in
backup-files
, but not the primary partition,
PARTONLY OFF specifies that the secondary partition is not backed up.
•
When converting files from one disk-process type to the other, using BACKUP with the
PARTONLY ON option skips all relative files and any DP1 entry-sequenced files that do not
have DP2 block sizes. For example, blocks of 1536, 2560, 3072, or 3584 bytes are not
compatible with DP2. An error message gives the names of the skipped files. You must back
up these files without the PARTONLY option.
•
If you specify PARTONLY ON, BACKUP backs up entire partitioned files that have some
secondary partitions on remote nodes if you include the DP2FORMAT option. BACKUP creates
the backup tape in format 2 and converts any DP1 files it encounters to DP2 format.
•
You cannot specify extent sizes with the PART option if your BACKUP command also contains
the PARTONLY ON option.
•
If you include the PART and PARTONLY ON options, BACKUP changes the name of the
secondary partition in the file label of the primary partition. If you include the PART option
without the PARTONLY option, BACKUP changes both the secondary-partition name in the
primary-partition file label and the actual file name of the secondary partition. (This case
applies only to Enscribe files because the PART option cannot be used with SQL files.)
