Administering Satellites Guide and Reference

Interactive Installation or Distributed Installation

You can install DB2 Satellite Edition using one of following two methods:

• Interactive installation. You will likely use an interactive installation for your initial satellite. You can also use this method to install your model office and test systems.
• Distributed installation using a response file. To perform a distributed installation, you can use a customized response file. This method is appropriate for mass deployments and the installation of hundreds or thousands of satellites, since the response file can be re-used to perform identical installations on different machines.

  You can use response files to install test satellites. You may need to perform many test satellite installations, and the response file install may be better suited for this task than an interactive install.

  Distributed installation also supports two unique features, which are not part of the interactive install. You can:

  • Specify to the installation program that the desktop shortcuts are not to be created. Use this feature if you want to initiate DB2 operations, such as synchronization, from your business application. This feature will allow you to hide DB2 from your users.
  • Specify the name of a client profile to be imported by the installation program. The installation will set up the connectivity information for the satellite. The information required to establish connections to the DB2 control server, the database containing the replication control tables, and the systems that the satellite will be replicating data with can be specified in the client profile. This feature is particularly important when performing mass deployments, because you do not have to configure each satellite separately.

  To prepare for mass deployment, the response file generator utility, db2rspgn, can generate a response file based on installed, configured, and tested model office. The response file generator can export a client profile from an existing DB2 system, such as Control Center, and provide a keyword to import this file in the generated response file. This response file can be used to install systems that will have the same components and configuration. The model office is normally used as a source to generate a response file.

  If you installed components on the model office that you do not want on the production or test satellites, the generated response file will install these components, unless you modify the response file to remove the selection of these components.

  For more information on response files and the response file generator, see Chapter 16, DB2 Satellite Edition Distributed Installation. For more information on mass deployment, see Chapter 10, Performing a Mass Deployment.
