volume
is the name of the volume where the secondary partition is to reside. If you omit the volume
name, RESTORE uses the original volume name of the secondary partition.
pri-extent-sizesec-extent-size
defines the primary and secondary extent sizes, respectively. The default value is 1 page (2048
bytes). You can specify these values for
pri-extent-size
and
sec-extent-size
:
0:512000000 [ PAGE[S] ]
specifies the extent size in pages (2048-byte units). The minimum extent size is one page,
so specifying 0 pages allocates one page (2048 bytes). PAGE is the default unit of
measurement.
0:2147483647 BYTE[S]
specifies the extent size in bytes. RESTORE rounds up to the next full page. For example,
if you specify 2047 bytes, RESTORE allocates one page; for 2049, it allocates two pages,
and so on.
0:2147483647 REC[S]
specifies the extent size based on the current settings for record length, data-block length,
index-block length, key-field lengths, and compression settings. RESTORE rounds up to the
next full page.
Guidelines
•
If you specify the PART option, you cannot specify the MAP NAMES option. The MAP NAMES
option provides a complete mechanism for changing file names; the PART option has limitations.
•
You cannot specify extent sizes with the PART option if your RESTORE command also contains
the PARTOF or PARTONLY option.
•
When you specify the PART option, the original name of the partition indicated by
sec-partition-num
is replaced by the new partition name you specify. The
sec-partition-num
parameter must already exist in the source file.
•
If you omit the volume name, RESTORE uses the original volume name of the secondary
partition.
•
You can use the PART option to specify the destination partition extent sizes when converting
files from one disk-process type to another.
•
If you use the PART and PARTONLY ON options, RESTORE changes the name of the secondary
partition in the file label of the primary partition. If you use the PART option without the
PARTONLY ON option, RESTORE changes the secondary partition name in the primary
partition file label and also changes the actual file name of the secondary partition.
CAUTION:
The PART option affects all partitioned files in
restore-files
. More than one
partition might have the specified
sec-partition-num
, so use the PART option carefully if you
are restoring more than one partitioned file.
