OLD-FILE-SAVE
Creates a tape comprising a files section only, with a format suitable for
loading on a 5.3 or 6.0 Reality system.
Caution
You must always perform a
VERIFY-SAVE immediately after completing a save procedure to
verify the integrity of the data saved to tape to ensure that it can be
restored.
The Migration Utilities
described in the optional manual
User's Guide to Reality Migration Utilities should be used in
preference to OLD-FILE-SAVE.
Should you decide not to
use the Migration Utilities, OLD-FILE-SAVE must be used in place of
FILE-SAVE where appropriate, to avoid file and/or item loss on restore.
However, there are a number of potential problems on restoring to a pre-7.0
Reality system - see Restrictions.
Command Class
Proc.
- SYSMAN and SYSPROG accounts only. If run from SYSPROG, accounts with
update/retrieval lock codes are not saved.
- Once restored, accounts must be updated using
UPDATE-ACCOUNT.
- Item-ids to be restored must not be more than 50 characters long.
- All data is saved, but very large items are truncated at maximum system size on
restore.
- Any single level files must have a data pointer in the dictionary.
- Binary items are not restored.
- Passwords are irreversibly encrypted. If passwords are not removed before
accounts are saved then, on restore, an encrypted form of password is expected
at the PASSWORD: prompt.
- The account to be saved must have MD entries of type Q for MD, Proc, and M/DICT.
- You should DX SYSMAN, SYSPROG, SYSFILES, HOTEL, English TUTORIAL ATP and DENAT
before the save.
- The save must be single reel.
Procedure
The procedure is very similar to the
FILE-SAVE procedure.
