Change file extension to php, then you upload file to oc-includes/osclass/core/caches/
And then define in config one of options.
// define('OSC_CACHE', 'redis');
// $_cache_config[] = array('default_host' => '127.0.0.1', 'default_port' => 6379, 'default_password' => ''); // TCP option
// $_cache_config[] = array('default_host' => '/usr/local/var/run/redis.sock', 'default_port' => -1, 'default_password' => ''); // Unix socket option
