Before you use this agent, perform the following tasks:

• Install the Apache server on shared or local disks.

• Ensure that you are able to start the Apache HTTP server outside of VCS control, with the specified parameters in the Apache configuration file (for example: /etc/apache/httpd.conf). For more information on how to start the server:

• Specify the location of the error log file in the Apache configuration file for your convenience (for example: ErrorLog /var/apache/logs/error_log).

• Verify that the floating IP has the same subnet as the cluster systems.

• If you use a port other than the default 80, assign an exclusive port for the Apache server.

• Verify that the Apache server configuration files are identical on all cluster systems.

• Verify that the Apache server does not autostart on system startup.

• Verify that inetd does not invoke the Apache server.

• The service group has disk and network resources to support the Apache server resource.

• Assign a virtual host name and port to the Apache server.

• Verify that you are able to start the Apache HTTP server outside of VCS control in non-interactive manner. For example, the startup command should not prompt for any password or any other interactive questions.
