Installing additional nodes for an HA cluster on a new Tomcat server

The following provides information and instructions for installing additional nodes for an HA cluster on a new Tomcat.

To install an addition node for an HA cluster on a new Tomcat

During subsequent node installations, previously installed nodes must be available so the newly added node can fully integrate into the cluster.

1. Ensure that all nodes are running and available.
2. Copy the cluster configuration file (created during the first node's installation) to the local file system before installing BMC Atrium Single Sign-On on the node.
3. Run the installation program, autorun.
    If autorun does not automatically launch the appropriate file, launch the setup executable located in the Disk1 directory of the extracted files. This script automatically detects the appropriate subscript to execute.
    (Microsoft Windows ) Run setup.cmd
    (UNIX ) Run setup.sh
4. Accept the default destination directory, or browse to select a different directory, and click Next.
5. Enter the host name if the provided name is incorrect and click Next.
6. Select Clustered Atrium SSO Server.
7. Select Add this node to an existing cluster.
8. Enter the location of the cluster configuration file and click Next.
9. Enter the LDAP port andLDAP replication port, and click Next.

10. Verify that Install New Tomcat is selected and click Next. 

    Note

    The BMC Atrium Single Sign-On Tomcat server cannot be shared with any product that integrates with BMC Atrium Single Sign-On. BMC recommends that BMC Atrium Single Sign-On be the only application in the Tomcat server.

11. Accept the default Tomcat server HTTP port number, HTTPS port number, and Shutdown port number or enter different port numbers and click Next.
     If any of the port numbers are incorrect, a pop-up menu identifies the incorrect port number and allows you to modify the selection.
     After the second node has been successfully installed, additional nodes can be added to the cluster by using the file created during the first installation.
