I have an OEM console running on an NT box with an 8i database running on the same machine. I also have an 8i database running on a Linux box. I have the IA running on the Linux box and when I discover the node from the console everything is listed (database and listener). I clicked on the "update TNS Names Entries" on the console after discovering the node. However, I cannot connect to the database on the Linux Box. (ORA-12545 - Connection failed, target host/object does not exist). I can discover and connect to the 8i database on the NT machine. Any suggestions.
