Reconfiguration using IFS Installer

Reconfiguration is very similar to doing a fresh installation except some parameters are reconfigurable while some aren't.

  1. Start the installer from <ifs_home> using the installer script.
  2. At the first screen select the option 'Reconfigure' and then press 'Next'.

  3. The following steps will look the same as in a fresh installation with a few exceptions. For more detailed information about each step please consult the main installation guide for the corresponding step. This guide will only focus on the reconfigurable steps and omit some steps that aren't of interest here.
  4. Configure database connection - It is possible to reconfigure the database. Enter the new database information as in during a fresh install and press 'Next'. Don't forget to update the passwords on the following form is necessary.
  5. Configure Dedicated Session Properties - Reconfigure the dedicated session properties. This work the same as during a fresh installation.
  6. Web Server Configuration - It is not possible to change the Listener port, but it is possible to use a custom access URL if adding an external load balancer.
  7. User Authentication configuration - Is is possible to change the user authentication mechanism as you please. Note that if you're changing the authentication mechanism you will have to enter all the required information as you would in a fresh installation.
  8. Java Virtual Machine settings for Managed Servers - It is possible to change the minimum heap size, the maximum heap size and the max perm size as well as the custom Java Classpath and the custom Java Parameters. Any previously entered value should display in the form which means it is also possible to remove custom values from the classpath or the parameter list. Any changes here will require a restart of the Managed Servers.
  9. Database Connection Pool Settings - The pool connection settings can be reconfigured. This will automatically trigger a restart of the Managed Servers.
  10. Cluster Member Configuration - Additional cluster nodes can be added or existing nodes can be deleted. Note that if there are any Managed Servers connected to a host you need to press 'Next' and remove all the Managed Servers connected to the node you wish to remove. (Press 'Next' again, then press 'Previous' twice to get back to this form).
  11. Managed Server - Add or remove Managed Servers in the cluster. Works the same as during a fresh installation. Note that if you're expanding the cluster (i.e. adding nodes) you need to perform some additional steps.
  12. SSL Configuration - It is possible to enable or disable SSL at any time.
  13. Press 'Execute' and wait for the reconfiguration to complete.
