Open System Services Management and Operations Guide (G06.30+, H06.08+, J06.03+)

• Files installed by PINSTALL are not always secured in conformance with the best practices at
your site. You should always resecure files installed by PINSTALL. For example, after installing
SQL/MX files, you might enter commands such as the following to secure the installed software
and the directories it uses:
find / -WNOE -WNOG \( -type d -o -type f \) -perm -o+w |
xargs chmod o-w
chmod a=rwxt /tmp /usr/tmp /var/tmp /var/preserve
/usr/tandem/sqlmx/USERMODULES
• Beginning with SPR T8626AAY and the G06.08 RVU, the PINSTALL utility should not be used
to install individual pax archives for these products:
◦ T8626
◦ T8627
◦ T8628
Use the COPYOSS macro instead. COPYOSS performs special processing for those
products.
When circumstances force the use of PINSTALL instead of COPYOSS for these products,
the operator must manually run the utility /bin/replace immediately after installing
the T8626 pax archive RELUTILS, then remove the /bin/replace utility from the OSS
file system.
This consideration was removed beginning with SPR T8626ABH and the G06.15 RVU.
Removing Obsolete OSS Files and Directories
When you update OSS products, you might need to remove files from previous RVUs.
The installation process places files containing lists of obsolete files in the directory
/etc/install_obsolete.
• If NonStop Software Essentials or DSM/SCM installed and maintains the OSS product files
in your OSS file system, you should do nothing with these files. Attempting to use the files for
maintenance will invalidate NonStop Software Essentials or DSM/SCM database information
about OSS product files on your system.
• If NonStop Software Essentials or DSM/SCM does not install and maintain OSS product files
in your OSS file system, you must manually remove obsolete files after installing any new
release version, RVU, or software product revision (SPR) and before using the merge_whatis
command.
You manually remove obsolete files by entering the following OSS shell commands:
cd /etc/install_obsolete
Pcleanup -r source
Note that the command Pcleanup starts with an uppercase letter.
You can also use the Pcleanup utility to:
• Display all obsolete files, by using the -i flag
• Move all obsolete files to /etc/install_obsolete, by using the -m flag
• Remove all files in the obsolete files source directory, by using the -r target flag
For additional information, see the Pcleanup(8) reference page either online or in the Open
System Services Shell and Utilities Reference Manual.
