cx_Oracle & Connecting to Oracle DB Remotely

Question

How do you connect to a remote server via IP address in the manner that TOAD, SqlDeveloper, are able to connect to databases with just the ip address, username, SID and pass

Answer 1

You can specify the server in the connection string, e.g.:

import cx_Oracle
connstr = 'scott/tiger@server:1521/orcl'
conn = cx_Oracle.connect(connstr)

• "server" is the server, or the IP address if you want.
• "1521" is the port that the database is listening on.
• "orcl" is the name of the instance (or database service).
