Chapter 3. Extending Prerequisite Scanner

IBM Prerequisite Scanner provides a basic set of collectors, evaluators, and
configurations that you can use to run the tool and scan for prerequisites. If the
basic set of files, the prerequisite properties and values, and the prerequisite checks
do not meet your requirements, you can extend Prerequisite Scanner.

Before you run Prerequisite Scanner

Before running IBM Prerequisite Scanner, determine whether the predefined
prerequisite properties, their expected values, and configuration files meet your
requirements for prerequisite scanning. If any of them do not meet your needs,
you can perform a set of prerequisite tasks to configure or extend Prerequisite
Scanner. The set of prerequisite checks and tasks is dependent upon the platform
and the number of prerequisite checks.

Required checks and extension tasks for Windows systems

You should perform a set of checks and tasks before you run the IBM Prerequisite
Scanner. These checks determine whether you can edit and use existing
configuration files or you must extend Prerequisite Scanner.
Table 12 provides a list of checks and tasks to perform.
Table 12. Checks and tasks before using a configuration file for Windows systems

operating system version to the file. For more
information, see "Adding product codes" on page
41.
v If yes, perform the next check.
v If no, create a configuration file to contain the
prerequisite properties for that operating system
and version of the operating system. For more
information, see "Creating custom configuration
files" on page 41.
v If yes, perform the next check.
v If no, add prerequisite properties. For more
information, see "Adding prerequisite properties"
on page 43.
v If yes, run the Prerequisite Scanner. For more
information, see Chapter 4, "Running Prerequisite
Scanner," on page 59.
v If no, edit the prerequisite properties. For more
