SAP Database link - Urgent

Does anyone out there know how to create a database link in a SAP database to another Oracle database. We are trying to go live with a new application at midnight tonight and the SAP administrator is on vacation and didn't leave instructions with his juniors on how to create this link.

Thanks

edit the tnsnames.ora on your $ORACLE_HOME/network/admin
and try it with command tnsping

after this you be able to create a database link from your schema with a comand:

SQL>create database link connect to
identified by using '';

hope this helps
