Here's another solution:
Check to see if your listener is using the 'tnslsnr' executable from a wrong ORACLE_HOME
(you can grep for 'tnslsnr' in Unix).
This could happen after an upgrade - your ORACLE_HOME get's upgraded but zombie listener hangs around, pointing to old ORACLE_HOME's version.
816 listener won't work if it's looking at 817 ORACLE_HOME.
Resolution: Stop (kill) the 'tnslsnr' process and restart using 'lsnrctl start'.
