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:
Install an L4 switch and ensure you use session persistence.
Deploy two or more separate, yet identical, instances of Self Service Password Reset.
Install and configure a Self Service Password Reset system.
Back up the configuration information. For more information, see Backing Up Configuration Information
in the Self Service Password Reset 4.4 Administration Guide.
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 4.4 Administration Guide.
Repeat these steps for each additional system you want to add.
Ensure that the L4 switch is configured to use sticky sessions. For a given browser session, the session must remain on the same Self Service Password Reset server over time unless the Self Service Password Reset becomes unavailable.
Follow the L4 switch documentation to configure the L4 switch to provide load balancing for the Self Service Password Reset computers.
As long as you use a remote database, you can view the status of the nodes in the L4 switch through the Configuration Manager. Click the Nodes tab in the Configuration Manager and you can see the status of the nodes. The node that is the master is the node that has been running the longest.
