Prerequisites

Before you install or upgrade the CA Network Flow Analysis software, perform the following tasks:

Obtain the CA Network Flow Analysis installation files from CA Technical Support. Then perform one of the following tasks:
- Burn the ISO files to a CD-ROM or DVD.
- Extract the contents of the ISO files by using an ISO image software application. Many ISO image applications are free.
Extract the appropriate files to the installation servers:
- Standalone servers:
  - NFHarvesterSetup9.1.2.exe
  - RAConsoleSetup9.1.2.exe
  - consoletool-exe.jar
- Windows Harvester servers in distributed architecture deployments:
  - NFHarvesterSetup9.1.2.exe
- Linux Harvester servers in distributed architecture deployments:
  - NFHarvesterSetup9.1.2.bin
- DSA servers in three-tier distributed architecture deployments:
  - NFDSASetup9.1.2.exe
You can install the software locally or remotely.
Install CA Performance Center 2.2.00 in your environment. CA Network Flow Analysis 9.1.2 is not compatible with previous versions of CA Performance Center.
Administrators use CA Performance Center for several administrative functions, including creating and managing groups, domains, user accounts, and user settings.
Assign a static IP address to the server. Set the Harvester server IP address to match the flow export destination that is assigned to each router.
Prepare the servers as described in the following sections:
- Preparing Windows Servers for the Upgrade
- Preparing Linux Servers for the Upgrade
In particular, verify that the servers meet the following requirements :
- (All Servers) The supported JRE version is installed: Java Runtime Engine (JRE) 1.6u41.
- (Windows Servers) The Service Control command (sc.exe file) is in the Windows System32 directory. This command is required for command-line operation. If the file is missing, the prerequisite check for it fails and the upgrade program exits.
- (Windows Servers) The .NET Framework version 3.5 SP1 is installed.
Disable the following third-party software on all installation servers:
- Server monitoring and maintenance software
- Antivirus
Note: When you enable antivirus scans later, exclude the CA Network Flow Analysis installation path and its subdirectories.
Exclude the following directories from real-time scans:C:\Windows\Temp and <NFA_install_path> and all its subdirectories. Real-time scans of these directories can corrupt the database.
Do not implement drive space compression on the installation server. Drive space compression can cause database losses and degraded system performance.
Stop other programs from running during the installation or upgrade.
Restart all servers to ensure that all the installed operating system patches are applied.
Ensure that no one else is logged in to the server during the installation or upgrade.

Note: If you exit from the upgrade program before the upgrade is completed, then restart the upgrade, the program resumes from your last saved change. The program does not start over from the beginning.
