3. Check state of versions currently installed:
• If the product is non-existent or corrupt, the task issues an error that says the
product cannot be configured and to use swinstall to install and configure
this product.
• If the versions currently installed are not configured and if the -u (unconfigure)
option is set, the system issues a note that the selected file or fileset is already
unconfigured.
• If the state of versions currently installed is configured, the check is affected
by the reconfigure option. A note saying the fileset is already configured
and will (reconfigure is true) or will not (reconfigure is false) be
reconfigured is issued.
4. Check for configuring a second version:
If the allow_multiple_versions option is set to false, an error is generated
stating that another version of this product is already configured and the fileset
will not be configured. If the option is set to true, the second version is also
configured.
5. Check states of dependencies needed:
• An error or warning is issued if a dependency cannot be met. This is controlled
by the enforce_dependencies option. If enforce_dependencies is set
to true the fileset will not be configured. If enforce_dependencies is false,
the fileset will be configured anyway.
• If the dependency is a prerequisite, the configuration fails.
• If the dependency is a corequisite, the configuration of this fileset will likely
succeed, but the product may not be usable until its corequisite dependency
is installed and configured.
Phase III: Configuration
In this phase, the actual software configuration takes place. Configure or unconfigure
scripts are executed and the software state is changed from installed to configured (or
unconfigured).
The purpose of configuration is to configure the host for the software and configure
the product for host specific information. For example, software may need to change
the host’s .rc setup, or the default environment set in /etc/profile. Or you may
need to ensure that proper codewords are in place for that host or do some compilations.
Unconfiguration reverses these steps.
The sequence of configuration tasks is shown below.
