Software Distributor Administrator Guide (September 2010)

• Configure scripts are for architecture-dependent actions because they will always
be run on the architecture of the install target.
• Configure scripts are the best place for removing files and updating the IPD, since
the system is not in transition (i.e. as in an update).
• A configure script can help with software updates as well as new installs. The
script must also be able to handle reinstallation and should include appropriate
error control if data destruction is possible.
11.5.6 Unconfigure Scripts
• Unconfigure scripts are executed during the Unconfiguration-Configuration phase
of a swremove session. They can also be executed by the swconfig command.
The pathname of the script being executed is:
$ {SW_CONTROL_DIRECTORY}unconfigure
• An unconfigure script is executed only for software installed into the primary root
(“/”).
• An unconfigure script is re-executed even when the product/fileset is in the
configured state.
• An unconfigure script is the primary way to move a product/fileset from the
configured state back to the installed state. The script should perform all (or most
of) the activities needed to disable the product/fileset for use.
• An unconfigure script must undo all configuration tasks performed by its
companion configure script. The user should be able to configure, unconfigure,
configure, etc. an installed product/fileset and always end up with the same
configured result.
11.5.7 Verify Scripts
• Verify scripts are executed by the swverify command. The pathname of the script
being executed is:
$ {SW_CONTROL_DIRECTORY}verify
• A verify script must not modify the system.
• A verify script is the primary way to check the configuration tasks performed by
a configure script for correctness and completeness.
• A verify script is executed for installations into the primary root (“/”) or an alternate
root. Since most of the actions of this script will involve checking the current
conditions of a configured product/fileset (in the primary root), it may not need
to perform any actions for a product/fileset installed into an alternate root directory.
• An environment variable, SW_IS_COMPATIBLE, can help a verify script determine
if installed software is compatible with the system on which it is installed. See
“SW_IS_COMPATIBLE” (page 281).
