Installing Remedy SSO in the high-availability mode using the TrueSight installer silently

Where you are in the Installation process

To install Remedy SSO using the silent TrueSight 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:

Step B: Install Remedy SSO on the secondary computer

1. Log in to the host computer on which you want to install Remedy SSO, and delete all the files from the temporary directory:

   • (Windows) %temp%

   • (Linux) /tmp

2. Extract the downloaded zip files (the installer) to a temporary location outside the following location to avoid any file sharing conflicts:

   • (Windows)C:\Program Files

   • (Linux) /opt

3. You will need to type the database administrator and database user passwords in an encrypted form in the tsso_silent.options file in Step 5. You can encrypt these passwords using the TrueSightRSSOMaintenanceTool through the wizard or command line interface:

    Encrypt password using the wizard

   1. Open the TrueSightRSSOMaintenanceTool by navigating to:
      • (Windows) <DownloadLocation>\RSSO\Windows\Disk1\Utility
      • (Linux) <DownloadLocation>/RSSO/Linux/Disk1/Utility 
   2. Run the tool, and click the Encrypt tab.
   3. Type the password, confirm it, and click Encrypt.
   4. Note down the encrypted password (from the Encrypted Password field).
    Encrypt password using the command line interface

   1. Navigate to the following directory:
      • (Windows) <DownloadLocation>\RSSO\Windows\Disk1\Utility
      • (Linux) <DownloadLocation>/RSSO/Linux/Disk1/Utility 

   2. Run the following command:

      • (Windows)

        TrueSightRSSOMaintenanceTool.cmd -silent -encrypt -encrypt -password=<password> -confirm_password=<password>

      • (Linux)

        ./TrueSightRSSOMaintenanceTool.sh -silent -encrypt -encrypt -password=<password> -confirm_password=<password>

        Note

        (Linux) If the password contains special characters, enclose the password using single quotes as shown in the following example:

        ./TrueSightRSSOMaintenanceTool.sh -silent -encrypt -encrypt -password='<password>' -confirm_password='<password>'

   3. Note down the encrypted password.

4. In the extracted folder, locate the tsso_silent.options file:

   • (Windows)<DownloadLocation>\RSSO\Windows\Disk1\

   • (Linux) <DownloadLocation>/RSSO/Linux/Disk1/

5. Open and edit the tsso_silent.options file. You can either retain the default values for the properties or change them, and save the file. The tsso_silent.options is a text file that defines the installation properties in the form of a prefix tag followed by a property name and value pair.

   • (Windows - Path with space) setup.exe -i silent -DOPTIONS_FILE="C:\temp folder\Disk1\tsso_silent.options"

   • (Linux - Path without space)./setup.bin -i silent -DOPTIONS_FILE=/opt/Disk1/tsso_silent.options
   • (Linux - Path with space)./setup.bin -i silent -DOPTIONS_FILE="/opt/temp folder/Disk1/tsso_silent.options"

7. You can periodically check the installation status by checking the truesightrsso_install_log.txt file located at: 

   • (Windows)%temp%

   • (Linux)  /tmp

8. Search for the following log message in the truesightrsso_install_log.txt file to ensure that Remedy SSO is installed successfully:
   Remedy Single Sign-On 18.02.00 for TrueSight 11.3.01 install succeeded.

9. Verify that the following environment variable points to the Remedy SSO installation path:

   • (Windows) %TRUESIGHTRSSO_HOME%

   • (Linux) $TRUESIGHTRSSO_HOME

10. You can either construct the Remedy SSO URL or locate the URL in the log file:

    • To define the URL, use the format: http(s)://<rsso_servername_FQDN>:<tomcat_port>/rsso
    • To locate the URL:
      1. Open the truesightrsso_install_log.txt log file from:
         
         • (Windows)<installationDirectory>\rsso\logs\

         • (Linux) <installationDirectory>/rsso/logs

      2. Search for the LOG EVENT that has the product URL as shown in the following example:

         • (Windows) LOG EVENT {Description=[PRODUCT URL],Detail=[product url: https://HostA.bmc.com:448/rsso]}

         • (Linux) LOG EVENT {Description=[PRODUCT URL],Detail=[product url: https://HostA.bmc.com:8048/rsso]}

11. Launch the Remedy SSO URL in a browser and log in to the Remedy SSO console using the default Admin credentials:

    • User name: Admin

    • Password: RSSO#Admin#

12. Change the password for the Admin user. Click Admin > Change Password.

13. Log out of the Remedy SSO console, and log in with the new Admin credentials.

    Your installation is complete if you are a Windows user.

14. (Linux) Configure the Remedy SSO service to restart automatically each time the Remedy SSO server is restarted:
    1. Log in to the host computer as a root user.

    2. From the command line, go to <installationDirectory>/rsso/bin, and run the following command:
       ./rsso service register <nonRootUserName>

       <nonRootUserName> refers to the name of the non-root user that you used for installing Remedy SSO.

    Your installation is complete.

Step C: 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.
