The command to connect to Oracle is usually SQL*Plus.

If you can be more specific about what you're trying to do, then it would be easier to assist you.

The command is sqlplus.

You need to set up your environment before you can use it:

. oraenv
(and when it asks, type in the DB SID)

sqlplus user/password[@database]

oraenv is usually in /apps/oracle/admin/bin

Hi Scott,

I used . oraenv on unix prompt but is displaying NO SUCH FILE AND DIRECTORY.
I also tried SqlPlus command eventhough it is saying Command Not Found....
is there anything I am doing wrong .
I am not clear with how to set up the enviornment variable.. Because i used SET command to check these variable but these are not there..

Speak with your database administrator(s) - you will not be able to connect to your database without more information...

If you don't know where an application or file is, "find" it
find / -name sqlplus -print

Hi Vijay.

Have you established that Oracle is installed in the first place? (assuming it's not your own server / Linux you're connected to - in which case you should know!).

id oracle

If that's OK, you need to find where the Oracle software is installed. Usually something like
/<<somewhere>>/oracle/product/<<version>>/...... etc.)

find / -name sqlplus -ls 2>/dev/null

if you have to.

If you find that, then oraenv should be in the same directory.
