IBM manual Considerations for a pruned DB2 installation

3.Use any of the installation methods discussed earlier to install and maintain a pruned DB2 installation image.

Considerations for a pruned DB2 installation

Consider the following precautions if you plan to prune a DB2 installation:

￿DB Setup wizard installation:

–With the TYPICAL installation, the regular TYPICAL components for that product are installed without the components removed by the db2iprune command.

–With the COMPACT installation, the regular COMPACT components for that product are installed without the components removed by the db2iprune command.

–With the CUSTOM installation, only the remaining components are displayed in the feature selection panel. The components removed by the db2iprune command are not displayed as optional components to install. However, the removed languages will still be displayed in the language selection panel. Ensure that you do not select a language that has been removed from the image using the db2iprune command. If you select a language that has been removed, you will receive an error message.

￿Response file installation:

–Ensure that you specify only the languages and features available in the DB2 pruned installation image. If your response file contains components that have been removed, you will get an error message.

–The db2iprune input file is used to specify which features and languages are to be removed from the DB2 install image, whereas the product response file is used to specify components that you want to install.

–The db2iprune input file is used to cut/remove unwanted features and languages from the install image, while the product response file is used to select components to be installed from the image. Therefore, any features and languages that were removed using db2iprune from the image cannot be installed if selected in the response file, and an error will be returned.

￿Fix pack considerations with db2iprune install

–As the DB2 fix pack installation image for Windows consists of a full installation image, the db2iprune command can be used with fix pack images. The fix pack application process is the same for full and pruned images. When the DB2 fix pack is installed, it detects and updates only the components that were installed using the db2iprune command and ignores any components that are not installed.
