3.4.3 Tru64 UNIX Rebranding Results in File Changes
As a consequence of the rebranding of Tru64 UNIX from the Compaq name to HP, the
following files have changed:
• version.abbrev_vendor from COMPAQ to HP
• version.banner from Compaq Tru64 UNIX to HP Tru64 UNIX
• version.vendor from Compaq Computer Corporation to Hewlett-Packard
Company
The .mrg..sysconfigtab file has been modified to incorporate these changes into
the generic sysconfig subsystem in the /etc/sysconfigtab file.
If the rebranding of HP Tru64 UNIX version information impacts any applications or
layered products, you can manually change generic system version attributes. See the
sysconfigtab(4) and sys_attrs_generic(5) reference pages for more information on how to
modify generic system version attributes.
3.4.4 Possible Performance Slowdown of Oracle 8.1.7 after Tru64 UNIX Rebranding
When kernel profiling and auditing were run on Oracle, under Version 5.1B-3 lots of
Asynchronous I/O + Direct I/O calls were seen. However, under Version 5.1B-4 no
Asynchronous I/O + Direct I/O calls (other than aio setup calls) were seen.
If this behaviour is seen on your system, you can modify /etc/sysconfigtab under
generic to change:
version_banner = HP Tru64 UNIX
version_avendor = HP
version_vendor = Hewlett-Packard Company
to
version_banner = Compaq Tru64 UNIX version_avendor
= COMPAQ version_vendor = Compaq Computer Corporation
Then reboot Version 5.1B-4 and check the Oracle performance.
