hi..
i'm running linux and oracle 9i,

me and my friends want a nice gui tool .. i found tora is such a tool ..
however it says i need to have oracle client installation..

i remember i installed 'database' not client in install time.

do i have to install this?
and then how? i have to run ./runinstaller again? (meaning i need Disk1/2/3 agian --)

also i have related question or doubt about options that i gave during installation.

listner doesn't run automatically when i startup oracle database? as u can see HOST=beautifulmind.something.org ( changed to something) and Service "mydb.beautifulmind.org"
which doesn't look right..
will this be a problem sometime? (well i don't know what listener is for) if so, how can i correct this..

thank you very much
