egroupware_official/setup/check_install.php
Ralf Becker 9a6b90e78f 1) enabled DB support additionaly for: 
- Oracle via oci8 or odbc extension
- MsSql via odbc extension
2) added checks for the neccesary extension incl. loading them if they are not loaded by default: db extensions and session extension. This is now consitent wiht check_install.
3) sessions class tries now to load the php session extension and silently fallbacks to db-sessions
