listener for 8i and 9i

Hi Friends,

We have an existing production 8i DB on our unix server
and its listener file is in $ORACLE_HOME8i/network/admin.

We installed a new 9i DB and its listenert is in
$ORACLE_HOME9i/network/admin.

Which listener should I start or use to connect to both DBs?

Thanks in advance friends

Either one. They are forward/backward compatible.

OH THANK VERY MUCH YOU FRIEND....:-* @};-
