Package groups and the shared resource directory

When you install a product package using IBM Installation Manager, you must choose a package group and a shared resource directory.

Package groups

During the installation process, you must specify a package group for the product package. A product package is the Rational® software product that you are installing. A package group represents a directory in which a product package shares resources with other product packages in the same group. When you install the product package using Installation Manager, you can create a package group or install the product packages into an existing package group. Some packages cannot share a package group, in which case the option to use an existing package group is unavailable.

When you install multiple product packages at the same time, all the product packages are installed into the same package group.

A package group is assigned a name automatically; however, you choose the installation directory for the package group.

After you create the package group by successfully installing a product package, you cannot change the installation directory. The installation directory contains files and resources that are specific to the product package that is installed into that package group. Resources in the product package that other package groups can potentially use are placed in the shared resources directory.

Shared resources directory

The Shared Resources directory is the directory where installation files are located so that one or more product package groups can use them. The default value for the Shared Resources directory is:
  • Windows®: C:\Program Files\IBM\RationalSDLC
  • Linux® and UNIX® systems: /opt/ibm/RationalSDLC
Important:
  • You can specify the shared resources directory once: the first time that you install a package. For the best results, use your largest disk drive. You cannot change the Shared resources directory location unless you uninstall all packages.
  • For Windows Vista, to enable users who do not have Administrator privileges to work with the product on a Windows Vista system, do not choose a directory in the C:\Program Files path.
