Some products are designed to coexist and share function
when they are installed in the same package group. A package group
is a location where you can install one or more software products
or packages. When you install each package, you select whether you
want to install the package into an existing package group, or whether
you want to create a package. IBM® Installation
Manager blocks the products that are not designed to share or do not
meet version tolerance and other requirements. If you want to install
more than one product at a time, the products must be able to share
a package group.
When a product is installed, its function is shared with
all of the other products in the package group. If you install a development
product and a testing product into one package group, when you start
either of the products, both the development and testing functionalities
are available in your user interface. If you add a product with modeling
tools, all of the products in the package group have the development,
testing, and modeling functionality available.
Note: If you install
several packages at the same time, they are all installed in the same
package group.
If you install a development product and
later purchase a development product with increased functionality
and add that product to the same package group, the additional function
is available in both products. If you uninstall the product with the
greater functionality, the original product remains
Note: Each
product installed into a unique location can be associated with only
one package group. A product must be installed into multiple locations
in order to be associated with multiple package groups.
Each
package group is assigned a name automatically. However, you choose
the installation directory for the package group.
When you create
the package group by successfully installing a package, you cannot
change the installation directory for the package group. The installation
directory contains files and resources specific to the packages installed
into that package group. Other resources in the packages that can
potentially be shared by other package groups are placed in the shared
resources directory.
Important: You can specify the shared
resources directory only the first time you install a package. For
best results, use your largest drive. You cannot change the directory
location later unless you uninstall all packages.
