Third-Party Provider Considerations
However, there are many different utility commands and many file-list and wild-card
possibilities. Some of them could have unanticipated interoperability considerations.
On systems on earlier RVUs, you can restore previously supported types of files from
backup tapes that also contain Format 2-enabled tables or their associated indexes or
views. Previous RVUs of Restore are able to bypass version 350 files on backup tapes
to restore other files on the tape, but they are unable to restore version 350 files.
Third-Party Provider Considerations
If you are a third-party provider of programs that run on HP NonStop S-series systems
and any of your programs use TMFARLIB to read the audit trail, these considerations
apply:
•
When your customers migrate to an RVU that supports SQL Format 2-enabled
tables, they will need new versions of your audit-reading programs before they can
introduce any Format 2-enabled tables that use the AUDITCOMPRESS option
onto their systems. The AUDITCOMPRESS option is the default when a SQL table
is created.
•
If your audit-reading programs call ARGETFIELDINFO or ARFETCHFIELDVALUE,
or if they call ARGETRECADDR for key-sequenced tables, you will need to provide
your customers with new versions of these programs that are rebound with the
version of TMFARLIB supplied with an RVU that supports Format 2-enabled tables.
Programs that are not rebound with the new version of TMFARLIB receive ARE-
INTERNAL-ERROR (-1000) when these calls are used against auditcompressed
audit records.
•
If any of your customers must fall back from an RVU that supports SQL Format
2-enabled tables to one that does not and if they have introduced any Format
2-enabled tables containing any Format 2 partitions onto their system, and if your
audit-reading programs might read any audit created before the fallback, they must
use versions of your programs bound with a version of TMFARLIB that contains
fallback support when they fall back:
°
The version of TMFARLIB supplied with RVUs that support Format 2-enabled
tables also contains fallback support. It detects when it is running on an RVU
that does not support SQL Format 2 partitions and then functions appropriately.
Therefore, your customers can use the same audit-reading programs you
provide for their migration when they fall back.
