A two-tier distributed deployment may include one or more Linux Harvester servers. To upgrade the Harvester software on a dedicated Linux server or virtual machine, complete the steps in this topic.
- Verify that the server is upgrade-ready as described in Verify That the Linux Servers Are Prepared.
- Log in to the NFA console server as a user who is a member of the Administrators group.
- Stop the pump service on the NFA console server:
- Click Start, Programs, Administrative Tools, Services.
- Right-click the NetQoS Reporter/Analyzer Pump service.
- Select Stop in the right-click menu.
The service stops.
- Log in to the Harvester server as root.
You can install the software locally or remotely--for example, by using ssh when you are logged in with root privileges.
Note: If you do not have root access, use an account with sudo privileges.
- Open a command prompt window.
- Run the following command to change the ulimit for the open files limit:
ulimit -n ulimit_number
Example:
ulimit -n 65536
- Prepare the installation/upgrade file for execution:
- Log in to the Harvester server as root.
You can install or upgrade the software locally or remotely--for example, by using ssh when you are logged in with root privileges. If you do not have root access, use an account with sudo privileges.
- Execute the chmod command on the file in a terminal window:
chmod u+x NFHarvesterSetup9.3.0.bin
- (Optional) Execute the list command to verify that the file is executable:
ls -al
The file permission settings are displayed.
- Run the installation or upgrade software:
./NFHarvesterSetup9.3.0.bin
The language selection screen opens.
- Verify that the appropriate language is selected, then click OK.
The Prior Installation Detected message opens.
- Review the message and click OK.
The Welcome screen opens.
- Click Next.

The Choose Install Folder screen opens. This screen displays the original root installation path as the default setting.
- Verify that the specified installation directory is correct, then click Next.
Important: If you do not use the original installation path, the upgraded software will not run properly.
If the program does not find certain expected 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 Pre-Installation Summary screen opens.
- Review the pre-installation information, then click Install.
The Installing Harvester screen opens. When the upgrade is complete, the Install Complete screen opens and reports any errors that occurred.

- Click Done.
The upgrade program closes. The Harvester is upgraded and the CA Network Flow Analysis services are started automatically.
- (Optional) Verify that the following conditions are met:
- (Two-tier architecture deployment) Harvester services are running.
- Harvester 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:
- Start MySQL by entering the following command in a Command Prompt window: mysql
