HP Tru64 Unix Release Notes for Version 5.1B-6 (5900-1150)

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.
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.
Error on Installing Japanese Advanced Printing Software Subsets
The following error messages are displayed when you install the IOSJPAPXBASE540 and
IOSJPAPXGUI540 subsets onto the system-installed APXBASE122 and APXGUI122 subsets:
Loading subset 1 of 2 ...
setld: Error installing Japanese Advanced Printing Software BASE and Client Commands
(IOSJPAPXBASE540)
This subset requires one or more additional subsets to operate correctly.
The following subsets are required:
"" (APXBASE120)
Please install required subsets first.
Loading subset 2 of 2 ...
setld: Error installing Japanese Advanced Printing Software Graphical User Interface
(IOSJPAPXGUI540)
This subset requires one or more additional subsets to operate correctly.
The following subsets are required:
"" (APXGUI120)
"Japanese Advanced Printing Software BASE and Client Commands" (IOSJPAPXBASE540)
Please install required subsets first.
These errors are caused by a dependency of the Japanese Advanced Printing Software subsets
on the corresponding original Advanced Printing Software subsets APXBASE120 and APXGUI120,
despite the changed subset names of APXBASE122 and APXGUI122 in APCD1 for the V5.1B-5
release.
You can avoid these errors by creating APXBASE120.lk and APXGUI120.lk files in the /usr/
.smdb. directory temporarily after installing APXBASE122 and APXGUI122 as following:
1. Log in as root and enter the following commands:
# cd /usr/.smdb.
# touch APXBASE120.lk APXGUI120.lk
2. Install the IOSJPAPXBASE540 and IOSJPAPXGUI540 subsets.
3. Remove APXBASE120.lk and APXGUI120.lk.
