Requirements

Server Operating System

OWA only runs under UNIX operating systems at this time. Windows operating systems are not currently supported.

PHP

OWA requires PHP 5.2.x or later.

Required php.ini Directives

Certain PHP configuration settings create problems for OWA installations. The following is a list of INI settings that should be avoided:

  • safe mode directive must be set to "off".

Required PHP Extensions

  • The PCNTL extension is required only if you plan to utilize OWA's background processing daemon (optional). Since PCNTL comes with the PHP distribution you just have to compile your PHP with the --enable-pcntl directive. See http://www.php.net/manual/en/pcntl.installation.php for more info on how to install the PCNTL extension.
