Reload Guidelines - HP T6553 D45 Reference Manual

FUP Commands
The RECLAIM option directs DP2 to mark data blocks vacated due to a DDL
"move partition boundary" or "one-way split" operation as FREE blocks.
The RECLAIM completes very quickly, but the EOF of the file may not be reduced
after a RECLAIM.
If the original goal of the partition split was to free space within the source partition
for future data insertion, the RECLAIM option is sufficient.
If the original goal of the partition split was to obtain maximum reduction of EOF,
omit the RECLAIM option which will compress the file data and eliminate FREE
blocks.
If the original goal of the partition split was to reduce disk space consumption by
the source partition and free up space for OTHER files on the disk, the RECLAIM
option must NOT be used. Use the DEALLOCATE option to return any freed
extents back to the disk volume's free space pool.
When a RELOAD with RECLAIM is in progress, a STATUS command for that file
will indicate RECLAIM IN PROGRESS and RECLAIM: YES
COMPACT
specifies that the file is compacted to reclaim free space and reduce file size.
However, using this option may take longer to reload a file.

RELOAD Guidelines


RELOAD must be used with a C30 or later product version of TMF. Using RELOAD
with earlier product versions of TMF might produce new information in the file that
is unrecoverable.

RELOAD does not require files to be audited.

If reload a volume directory during a peak production period, run RELOAD at a low
rate to reduce the degradation of system performance caused by the RELOAD.

D-series software supports allocation (with the ALLOCATE command, for Enscribe
only) and deallocation of volume directory extents, with the [NO] DEALLOCATE
parameter.
This deallocates unused extents when you issue the RELOAD command against a
volume directory. If you want unused extents in a directory, use the ALLOCATE
command after each reload.

When you issue a RELOAD command, FUP creates an online reload server
(ORSERV) process (on the node of the file) to perform the reload. If FUP cannot
create the ORSERV process, an error message appears.

The ORSERV process created by a RELOAD command runs in the NOWAIT state.
While the reload operation is processing, FUP displays its hyphen (-) prompt so
you can perform other FUP operations.
