Separating configuration from installation
The InfoSphere® MDM installation application enables you to install or modify the product while generating configuration properties files that you can use to configure the product at a later point in time.
About this task
The standard InfoSphere MDM installation process involves configuring key properties of the deployment at the same time as the installation occurs. However, with the separation feature, you can separate the installation from the configuration of application properties, the database, user interfaces, and other key properties and variables.
When you select the option to separate the configuration from installation, the installation application will generate a number of properties files that track the selections you have made in the IBM® Installation Manager session. These properties files are stored in MDM_INSTALL_HOME/properties. You can manually edit these generated properties files to change the product configuration, and then use scripts to apply the new configuration to an existing instance without having to complete a full reinstallation.
The configuration separation capability can also be used when you modify an installed product to include new components. Once the separation option is selected, you must always follow an IBM Installation Manager Modify session by running the madconfig script to complete the modification.
