2.2 High Availability and Load Balancing

Self Service Password Reset supports high availability and load balancing for user authentications through an L4 switch. You must install and deploy the L4 switch in your environment ensuring that you use session persistence. Self Service Password Reset uses your browser's session storage to facilitate seamless high availability and load balancing. As users are working and their existing sessions change, Self Service Password Reset requires the users to reauthenticate before they can continue their work.

To enable the load balancing and high availability for users authentications:

  1. Install an L4 switch and ensure you use session persistence.

  2. Deploy two or more separate, yet identical, instances of Self Service Password Reset.

    1. Install and configure a Self Service Password Reset system.

    2. Back up the configuration information. For more information, see Backing Up Configuration Information in the Self Service Password Reset 4.1 Administration Guide.

    3. Install the second Self Service Password Reset system, then import the configuration information from the first system to the second system. For more information, see Importing Configuration Information in the Self Service Password Reset 4.1 Administration Guide.

    4. Repeat these steps for each additional system you want to add.

  3. Ensure that the Self Service Password Reset computers and the L4 switch are in the same subnet.

  4. Follow the L4 switch documentation to configure the L4 switch to provide load balancing for the Self Service Password Reset computers.

There are no additional configuration steps in Self Service Password Reset to make the load balancing and high availability work.
