STORE and TurboSTORE/iX Command Options
STORE Options
you might enter the following:
:FILE T;DEV=TAPE
:STORE @.OPERATOR.SYS;*T;TRANSPORT;FILES=6000
Use the MPE/iX RESTORE command to restore files from MPE V/E format backup tapes to
an MPE/iX system. MPE/iX RESTORE automatically detects that the tapes are in MPE V/E
format, and invokes CM(RE)STORE (Compatibility Mode Restore) to restore the files.
Managing File Security (COPYACD and NOACD)
An additional way to manage the security of files being stored is to use the COPYACD and
NOACD options. The default is COPYACD. This means that in addition to the MPE security
matrix, a file's ACD (if one exists) is written to backup. This allows you to store the extra
security information associated with an ACD.
If for some reason you want to store files without their ACD, the NOACD option can be
specified. This would remove the extra security associated with ACD's, which may be
desired if you are moving files to a system where the current ACD's would be inapplicable
or undesired. When using these options, keep in mind that RESTORE also has COPYACD and
NOACD options. So, even if you create a STORE media with ACD's, you have the choice at
RESTORE time to restore or not restore the ACD information.
Storing Files with Certain File Codes (FCRANGE)
Use the FCRANGE parameter to store files with certain file codes. MPE XL file codes
distinguish different types of files. You can select up to eight file code ranges to store. For
example, files with codes 1100, 1101, and 1102 are HPWORD files. Files with codes 1152
and 1153 are SLATE files. To store all HPWORD and SLATE files in the LETTERS group of
the PERSONEL account enter:
:FILE T;DEV=TAPE
:STORE @.LETTERS.PERSONEL;*T;FCRANGE=1100/1102,1152/1153
Improving Storing Efficiency by Increasing Record Size
(MAXTAPEBUF)
Files are stored with greater efficiency by using the maximum backup record (buffer) size
allocated to a given backup device. Performance increases because data transmission is
more efficient and because the amount of media used for interrecord gaps decreases.
The maximum backup record size of MPE/iX supported backup devices differs from device
to device and is shown in Table 6-1.
