mkusil Command
Purpose
Creates or attaches a new user-specified installation location (USIL) instance.
Syntax
Description
The mkusil command creates or attaches a new USIL instance.
A user-specified installation location (USIL) is a tracked, relocated installation path that is created by the administrator. The location is tracked by the system and can be used as an alternate installation path for packages that use relocation of file sets or software. Multiple instances or versions of the same software package can be installed on a single system by delegating each installation to a separate USIL. An existing USIL instance can be attached or detached from any given system.
Each
USIL instance maintains its own set of Software Vital Product Data
(SWVPD) in three installp parts:
- InstallRoot/etc/objrepos
- InstallRoot/usr/lib/objrepos
- InstallRoot/usr/share/lib/objrepos
Tip: Current SWVPD object classes
include product, lpp, inventory, history, fix, vendor, and lag. Each
USIL instance mirrors the default SWVPD structure within the relocated
path.
