After my first installation blank screen with Database update needed.

Is this happening when you go into the installation routine install/install.php?

Yes, now I am getting the following error in /var/log/httpd/error_log

[Wed Dec 12 11:23:25 2012] [error] [client 10.201.92.104] PHP Fatal error: Call to undefined method mysql_driver_ADOConnection:isconnect() in /var/www/html/doc/inc/inc.ClassSettings.php on line 991, referer: http://10.201.110.196/doc/install/install.php

That error message is due to a minor error in inc/inc.ClassSettings.php.
The database connection is closed, even if it could not be opened successfully. The actuall problem in your case appears to be a failed database connection.
