Backing Up and Restoring OSS Files
You create or update a whatis database file by merging whatis database fragment
files using the merge_whatis utility. Each whatis database fragment file has an
OSS filename with the form whatis.piece, where piece varies according to the
product containing the reference page files.
The whatis database fragment file for each product shipped as part of Open System
Services is automatically installed into the appropriate one of the following directories:
/usr/share/man/whatis.frag
/nonnative/usr/share/man/whatis.frag (G-series only)
To merge these whatis.piece files into the corresponding whatis database after
installing an update to Open System Services, enter the following commands from an
OSS shell prompt:
merge_whatis
merge_whatis /nonnative/usr/share/man (G-series only)
The corresponding whatis databases are now available for use with the following
MANPATH variable values:
/usr/share/man (the default value)
/nonnative/usr/share/man (G-series only)
You can verify the existence of the whatis databases by entering the OSS shell ls
command for each of these MANPATH variable values.
Your site can acquire additional products to install in the OSS environment. If these
additional products include reference pages, you need to add entries to an existing
whatis database or create a new whatis database for a new MANPATH variable
value.
For additional information about the merge_whatis utility, see the
merge_whatis(8) reference page either online or in the Open System Services
Shell and Utilities Reference Manual.
Backing Up and Restoring OSS Files
This subsection describes the tasks for backing up and restoring the OSS environment
and user files on your system.
OSS files can be backed up with the OSS pax command or the BRCOM interface for
Backup and Restore 2.0. An entire OSS fileset can be backed up by using its mount
point as the current directory when running either utility.
System administrators familiar with Guardian tools can use Backup and Restore 2.0 for
almost all archiving tasks. Administrators more familiar with UNIX can use pax;
however, the pax utility has several restrictions:
•
A pax archive has the same file size limit as other OSS files; that limit might
prevent complete backup of a large fileset or directory tree.
