Upgrade the DSA in a Three-Tier Distributed Deployment

In a three-tier distributed deployment, each DSA is installed on a separate server. Complete the steps in this topic to upgrade a DSA on a dedicated Windows server or virtual machine.

Note: If you have a Linux DSA, contact your CA Support Availability Manager or Sales Account team to inquire about obtaining a Windows-based DSA.

Follow these steps:

1. Verify that the installation server meets the following requirements:
   • The server is upgrade-ready as described in Verify That the Windows Servers Are Prepared.
   • The Harvester servers have been upgraded.
2. Verify that processing is complete for the collected DSA data:
   1. Log in to the NFA console server with an account that has administrator privileges for CA Network Flow Analysis.
   2. Locate the following directory on the NFA console server: <install_path>\Reporter\datashare\data\<DSA_server_IP_address>
   3. Verify that the directory does not contain any .csv files. If .csv files are present, keep checking until the files are gone. The files are processed and gone within 15 minutes.
3. Log in to the DSA server as a user who is a member of the Administrators group.
4. Start the upgrade: Double-click the DSASetup9.3.0.exe file in Windows Explorer.

   The language selection screen opens.

5. Verify that the appropriate language is selected, then click OK.

   The License Agreement screen opens.

6. Review and accept the license agreement:
   1. Read the license agreement and scroll down.
   2. If you want to continue, click the option to accept the license agreement. This option is activated when you scroll to the bottom.
   3. Click Next.

      Prerequisite tests look for problems and may cause an error message to open.

7. If the Pre-requisite Check Warning message opens, review it, correct or note any non-critical problems, then click OK.

   The Choose Install Folder screen opens and displays the original root installation path as the default setting.

8. Proceed through the options to verify the installation directories:
   1. Click Next.

      Important: You must use the original installation path or the upgraded software will not run properly.

      If the program does not find certain directories in the installation path, an error message opens and the upgrade stops. This problem does not occur when the previous software installation is fully functional.

      The Select a Location for the MySQL Data Directory screen opens, which shows the original installation path for the MySQL data directory.

      The Folder Selected Is Not Empty message also opens, which asks you to verify that you have backed up the directory contents.

   2. Click Next in the Select a Location for the MySQL Data Directory screen.

      Important: You must use the original installation path for the MySQL data directory.

      The Select a Location for the MySQL Temp Directory screen opens, which shows the original installation path for the MySQL tmp directory.

   3. Click OK.
   4. Click Next.

      Important: You must use the original installation path for the MySQL temp directory.

      MySQL is configured, then the Pre-Installation Summary screen opens.

   5. Click Next.

      Important: You must use the original installation path for the MySQL temp directory.

      MySQL is configured, then the Pre-Installation Summary screen opens.

9. Review the pre-installation information, then click Install.

   The Installing DSA screen opens. When the upgrade is complete the Install Complete screen opens and reports any errors that occurred.

10. Click Done.

    The upgrade program closes. The DSA is upgraded and the DSA services are restarted.

11. (Optional) Verify that the following conditions are met:
    • DSA services are running.
    • The DSA is receiving data.
    • The revision history shows that the component is upgraded to the correct version. To display the revision history, complete the following substeps:
      1. Start MySQL by entering the following command in a Command Prompt window: mysql
      2. Display the revision history by entering the following command:
         select * from revision_history
12. (Optional) Check the DSA_Install_<timestamp> log periodically. This log is located at the install path root level--for example, in the \\CA\NFA directory. Use the log to monitor the migration of the DSA database tables to the new format.

    The migration of DSA database table data begins as soon as the CA NFA DSALoader service restarts. The DSA_Install log lists the tables as they are migrated. Nine tables are migrated for each agent or interface. If you have many agents and an extensive amount of stored data, migration may continue for some time.

Next:

• To upgrade an additional DSA on another server, repeat these steps.
• To upgrade the console server, go to the next topic.
