To upgrade Remedy SSO in a HA environment using the Remedy installer silently
The Remedy SSO Admin UI requires sticky session/Session Persistence in an HA environment. Usually, this is accomplished by enabling sticky session/Session Persistence on the load balancer. Different load balancers have different configurations to enable a sticky session/Session Persistence. Refer to the specific load balancer documentation or ask the vendor for details about the configuration.
Note that when sticky session/Session Persistence is not enabled for the Remedy SSO Admin UI, the admin user behind the firewall can use a specific Remedy SSO server hostname to access admin UI instead of using the load balancer URL.
You need to perform the following tasks to upgrade Remedy SSO using the options file silently in the high-availability mode:
- Ensure that Remedy SSO is upgraded successfully on the primary node as outlined in upgrading .
Unzip the Remedy SSO files on the additional node.
Upgrade Remedy SSO on the additional node as outlined in upgrading .
- Complete the rest of the installation steps.
- (Optional) Reconfigure the SAML authentication.
To configure the SAML authentication settings after you upgrade
For each realm that is configured for SAML authentication, perform the following steps:
- Edit the realm to enter PEM encoded IdP signing certificate data in the IdP Signing Certificate field or import the IdP metadata again. Ensure that the other SAML configuration is same as before except the IdP Signing Certificate field data.
- Save the details.
When you configure the SAML authentication parameters for the Presentation Server, you must set the User ID Transformation field to RemoveEmailDomain and enable the Force Authentication check box.
If you had modified the web.xml file during the upgrade, ensure that you reapply the changes after the upgrade.
