RESTORE
Database corruption may result if not all database files are restored from a
backup. Be sure that you only want to restore certain database files before
overriding the default behavior with ;PARTIALDB.
THE FOLLOWING OPTIONS ARE AVAILABLE ONLY IF TURBOSTORE XL OR
TURBOSTORE XL II IS INSTALLED ON YOUR SYSTEM. TURBOSTORE IS NOT PART
OF THE FUNDAMENTAL OPERATING SYSTEM, BUT MAY BE PURCHASED
SEPARATELY.
For additional information on TURBOSTORE XL, refer to the Store and Turbostore/iX
Manual (30319-90001).
RESTORESET Specifies parallel and sequential backup devices. This option cannot be use
if the restorefile parameter is specified.
Consecutive tapes are specified in the following way:
;RESTORESET = (*tape1,*tape2,*tape3,...)
This instructs MPE/iX to use only one drive at a time for the restore. When
the first reel of tape is exhausted, RESTORE will shift to the next available
drive, leaving the first free for rewinding and changing reels. Thus, at any
given time, only one drive is restoring files and the effect is to accelerate
the restore process.
In the following example, all three tapes will be used in parallel during the
restore:
;RESTORESET=(*tape1),(*tape2),(*tape3)...
In the following example, sets of tapes are used sequentially for the
restore. Two tapes would be restoring at any particular moment, while the
other two are rewinding so that the operator may switch reels.
;RESTORESET=(*tape1,*tape2),(*tape3,*tape4)
This option cannot be used if the restorefile parameter is specified.
device Specifies the device from which the file is to be restored. It must be a
magnetic tape or DDS. This device should be specified in a file equation
before you invoke the RESTORE command, ie:
FILE DEVICE;DEV=TAPE
This file equation can also specify a remote device or a disk file.
MOSET Specifies parallel Magneto Optical (MO) backup devices. This option is not
available if the storefile option is specified.
Parallel devices are specified by either of the two following commands:
;MOSET = (12),(13),(15)
;MOSET = (MO),(MO),(MO)
All MO devices are used in parallel during the restore. The preferred
format is specifying just "MO", since RESTORE will use the the NAME
parameter to locate the correct media.
This option is not available if the restorefile option is specified.
