machine or product. In a standard system, the root parts
of a product are stored in the root (/) file tree. The
/etc/objrepos directory contains the root part of an
installable software product.
usr The usr part of a software product contains the part of the
product that can be shared by machines that have the
same hardware architecture. Most of the software that is
part of a product usually falls into this category. In a
standard system, the usr parts of products are stored in
the /usr file tree.
share The share part of a software product contains the part of
the product that can be shared among machines, even if
they have different hardware architectures (this would
include nonexecutable text or data files). For example, the
share part of a product might contain documentation
written in ASCII text or data files containing special fonts.
To verify that the root (/), /usr, and /usr/share parts of the system are valid with
each other, use the following command:
lppchk -v
11.1.3 Software states
This command verifies that all software products installed on the / (root) file
system are also installed on the /usr file system and, conversely, all the software
products installed in the /usr file system are also installed on the / (root) file
system.
The installed software or software update can stay in one of the following states:
► Applied
► Committed
If the service update was not committed during installation, then you must
commit it after installation once you have decided that you will not be returning to
the previous version of the software. Committing the updated version of the
service deletes all previous versions from the system and recovers the disk
space that was used to store the previous version. When you are sure that you
want to keep the updated version of the software, you should commit it. To
commit the fileset bos.sysmgt.trace that is currently applied but not committed,
use:
installp -c bos.sysmgt.trace
