To install Remedy SSO using the wizard-based Remedy installer in the high-availability mode
Remedy Single Sign-On high-availability environment is implemented as a redundant system with session failover. If the primary node fails, the load is transitioned to the secondary node with minimal interruption.
In a high-availability (HA) environment, multiple instances of the Remedy Single Sign-On (Remedy SSO) web application are deployed to form a cluster. Usually, a load balancer is used as a front end to the cluster, giving the external applications the appearance of a single server. The load balancer distributes requests among Remedy SSO nodes. However, there is no requirement for a sticky session, because requests can be handled by any instance.
You need to perform the following tasks to install Remedy SSO in a high-availability mode:
Before you install or upgrade Remedy SSO in an HA environment and if you choose to configure/use PostgreSQL, download PostgreSQL from their official site, and then install and configure it. When you run the Remedy SSO installer, select the external database option and not the embedded one.
- Ensure that Remedy SSO is installed successfully on the primary node as outlined in .
Unzip the Remedy SSO files on the additional node.
- Run the installation program.
Click Next to confirm the database settings. The database settings should be same as the settings used by the primary node.
In the window to assign database users, select the Use Existing User option.
When you add nodes, select the Use Existing User option and enter credentials that are used by the primary node.
- Complete the rest of the installation steps.
Set up and configure the load balancer details
Set up the load balancer on a host computer other than the primary and secondary Remedy SSO host computers. Refer to the specific load balancer documentation or ask the vendor for details about the configuration.
