Hi all!
I tried to update Oralce 8.1.7 to 9.2.0.4. The Installation of the new Software worked without Problems. But when I start the "Database Upgrade Assistant" I got following Error MEssage: <b>ORA-12560: TNS:protocoll Adapter error</b>.
Perhaps somebody can give me a hint? (8.1.7 with all Services is running)
