OSS Large Files
DP2 has a dependency on DSAP/DCOM. If you install the DP2 fallback SPR
(T9053AQM), you must also install T9543H01^ABH as described under DSAP/DCOM.
DSAP/DCOM
Migration
The DSAPDDL file is changed in the product revision of DSAP/DCOM delivered in the
H06.06 and later RVUs (T9543H01^ABH), resulting in changes to the work file layout.
You must use the DSAPDDL file distributed with T9543H01^ABH when running
ENFORM queries on the work file created using this SPR. The DSAPDDL file for
T9543H01^ABH contains these changes to the directory-record structure:
•
The field named fifth is changed from type binary unsigned to type binary 32
unsigned.
•
These fields are added to the end of the structure:
°
Field flab2_flags1 of type binary unsigned identifies OSS files larger than 2
GB.
°
Field ext-0-fsu of type binary unsigned contains the extent size of large
OSS files for extent number 0.
°
Field ext-1-128-fsu of type binary unsigned contains the extent size of
large OSS files for extent number 1-128.
Fallback
The H06.06 and later versions of DSAP/DCOM (T9543H01^ABH) are large OSS file
safe, but pre-H06.06 versions are not. If you fall back from H06.06 or later to an earlier
RVU, HP recommends that you install T9543H01^ABH during the fallback.
Backup and Restore 2 Fallback
OSS files larger than 2 GB that have been backed up cannot be restored to a pre-
H06.06 system. Install the Backup and Restore 2 fallback SPR T0744H01^AAA to
restore files smaller than 2 GB in the following situations:
•
If you have a backup tape with a mix of OSS files smaller than 2 GB and larger
than 2 GB. You can restore the smaller files to an H06.05 file set by first installing
T0744H01^AAA.
•
If you have created backup tapes on H06.07 and you are falling back to H06.05.
Note. An application that is “large file safe” causes no data loss or corruption when it
encounters an OSS file larger than 2 GB. It may not necessarily have the capability to process
OSS files larger than 2 GB, but it has the appropriate logic to handle errors or warnings
detected during file manipulation operations and fail gracefully.
