you can check wheher there is a process listening on port 1521. but this won't work in all cases
You could try and load the oracle supplied JDBC driver; if it throws an exception, most likely ClassDefNotFound, the database probably isn't there ...

Hi
A long time ago I worked with Oracle on Unix.
To MaxMaxic's suggestion:
in oratab can be several "last"-lines (for every instance one line):
Dxyz:/usr/local/public/Ora
Txyz:/usr/local/public/Ora
Pxyz:/usr/local/public/Ora
Exyz:/usr/local/public/Ora
The first field tells you the Instance-Name (* = all),
The second field tells you the home-directory of oracle
The third field tells you if the database-instance will be startet up at unix-startup (N=no, Y=yes).
So if you'll find there a "Y" then this will definitive be an oracle server installation. Otherwise you can still look for the directory MaxMaxic mentioned. - But on my client installations there was usually also a directory .../OraHome1/dbs.
The default value of the third field is "N". So if the database administrator did not modify this file, it gets a little bit triggy to figure out "server installation or not".
A running oracle you can find with "ps -ef | grep oracle"
I hope this helps also

No comment has been added lately, so it's time to clean up this TA.
I will leave a recommendation in the Cleanup topic area that this
question is:
- split points between CEHJ and MaxMaxic
Please leave any comments here within the
next seven days.
PLEASE DO NOT ACCEPT THIS COMMENT AS AN ANSWER !
