Oracle is installed on a diffferent system. I have to connect to it. How?
I have connected in DreamCoder using TCP/IP.
Machine name : 171.220.110.102
Instanece : Raghu
Port : 1521
but how to do this in PL/SQL Developer
You will need to use the Oracle Net Configuration Assistant (a standard Oracle utility) to define a local service name for the remote databases you want to access from your Oracle Client.
Hi, Its fine, but i dont have persmission to install it in my system(office). Is there any other way to connect without installing it ?
But i am able to connect to DB from dreamcoder.
The minimal requirement is the Oracle Instant Client. It can be used without an actual "installation", so it does not require many privileges. Just copy some files and set the ORACLE_HOME and TNS_ADMIN environment variables.
I would check if you have the basic components to connect to your database instance from your development machine. Seehttp://www.orafaq.com/wiki/Tnsping
That has to work first.
(It establishes if you have a valid Oracle setup there)
