To Configure the OpenSSO Enterprise Load Balancer

1. Access https://is-f5.example.com, the BIG-IP load balancer login page, in a web browser.

2. Log in using the following information:

   User name:

   username

   Password:

   password

3. Click Configure your BIG-IP (R) using the Configuration Utility.

4. Create a Pool.

   A pool contains all the backend server instances.

   1. In the left pane, click Pools.

   2. On the Pools tab, click Add.

   3. In the Add Pool dialog, provide the following information.

      Pool Name

      OSSO-Pool

      Load Balancing Method

      Round Robin

      Resources

      Add the IP addresses and port numbers for the OpenSSO Enterprise servers: osso-1:1081 and osso-2:1081.

   4. Click Done.

5. Add a Virtual Server.

   The virtual server presents an address to the outside world and, when users attempt to connect, it would forward the connection to the most appropriate real server.

   Note –

   If you encounter JavaScript^TM errors or otherwise cannot proceed to create a virtual server, try using Internet Explorer.

   1. In the left frame, click Virtual Servers.

   2. On the Virtual Servers tab, click Add.

   3. In the Add a Virtual Server dialog box, provide the following information:

      Address

      Enter the IP address for lb-2.example.com

      Service

      1082

   4. Continue to click Next until you reach the Pool Selection dialog box.

   5. In the Pool Selection dialog box, assign the OSSO-Pool Pool.

   6. Click Done.

6. Add Monitors.

   OpenSSO Enterprise comes with a JSP file named isAlive.jsp that can be contacted to determine if the server is down. Since we have not yet deployed OpenSSO Enterprise, isAlive.jsp cannot be used. In the following sub procedure, create a custom monitor that periodically accesses the Application server instance(s). If desired, the monitor can be changed later to use isAlive.jsp.

   1. Click the Monitors tab

   2. Click the Basic Associations tab

   3. Find the IP address for osso-1:1081 and osso-2:1081.

   4. Mark the Add checkbox for OSSO-1 and OSSO-2.

   5. At the top of the Node column, choose the tcp monitor.

   6. Click Apply.

7. Configure the load balancer for persistence.

   1. In the left pane, click Pools.

   2. Click the name of the pool you want to configure; in this case, OSSO-Pool.

   3. Click the Persistence tab.

   4. Under Persistence Type, select Passive HTTP Cookie.

   5. Under Cookie Name, enter amlbcookie.

   6. Click Apply.

8. In the left pane, click BIGpipe.

9. In the BIGpipe command window, type the following:

   makecookie ip-address:port

   ip-address is the IP address of the OSSO-1 host machine and port is the same machine's port number; in this case, 1081.

10. Press Enter to execute the command.

    Something similar to Set-Cookie: BIGipServer[poolname]=692589248.36895.0000; path=/ is displayed. Save the numbered value (in this case, 692589248.36895.0000) for use in To Create a Site on OpenSSO Enterprise 1.

11. In the left pane, click BIGpipe again.

12. In the BIGpipe command window, type the following:

    makecookie ip-address:port

    ip-address is the IP address of the OSSO-2 host machine and port is the same machine's port number; in this case, 1081.

13. Press Enter to execute the command.

    Something similar to Set-Cookie: BIGipServer[poolname]=692589248.12345.0000; path=/ is displayed. Save the numbered value (in this case, 692589248.12345.0000) for use in To Create a Site on OpenSSO Enterprise 1.

14. Log out of the load balancer console.
