Software Distributor Administration Guide HP-UX 11i v1, 11i v2, and 11i v3 (5900-2561, March 2013)

• Filesets or products can include configure (unconfigure) scripts.
• The swinstall and swremove commands do not automatically run configuration scripts
when you specify an alternate root directory with these commands. You must run swconfig
to configure or unconfigure alternate roots.
• Automatic configuration can also be postponed on software installed to the root directory, /
(for example, when multiple versions are installed), by using the defer_configure command
option with swinstall or swremove.
• By default, swconfig only supports configuration of compatible software. You can switch
this feature on or off with the allow_incompatible option.
• If a fileset relies on another software product for proper operation, that software product must
be in a configured state and is controlled by the enforce_dependencies option.
• The swconfig command configures only one version of a fileset at a time, controllable through
the allow_multiple_versions option.
• The swconfig command moves software between the installed and configured states.
• The swconfig command uses dependencies to automatically select software on which to
operate (in addition to any software you specify directly). See “Software Dependencies ”
(page 22) for more information.
NOTE: When a swinstall session includes a reboot fileset (such as when you update the core
HP-UX operating system to a newer release), the configure scripts are automatically run as part of
the system start-up process after the system reboots. You do not have to run swconfig to complete
the configuration.
2.2.2 The Configuration Process
The configure process has three phases: selection, analysis, and configuration.
Phase I: Selection
In this phase, swconfig resolves the software selections. The swconfig behavior can be controlled
using the enforce_selections option. If set to false (default), swconfig proceeds even
when only one software selection is available in the source. If set to true, swconfig proceeds
only if all of the software selections are available.
Phase II: Analysis
In this phase, swconfig determines if the software can be configured successfully (includes checks
of software existence, prerequisites). If you execute swconfig with the -p (preview) option, the
command stops after completing analysis and does not change anything on the host.
Analysis takes place on the local host. The configuration phase will not take place if any errors
occur during analysis. Errors in the analysis phase will only exclude those products that had errors
in them. If only warnings occur, the task continues.
The sequential analysis tasks on the host are:
1. Initiate analysis.
2. Process software selections:
Get information from the Installed Product Database and check for compatibility.
The system checks that all software is compatible with the host’s uname attributes. This check
is controlled by the allow_incompatible command option. If it is set to false, the system
produces an error; if set to true, it produces a warning.
