DPY-4011: the database or network closed the connection

Question

I am using Oracle 11.2.0, Python 3.10.3

I am trying to connect to a Infor Oracle database with the following script:

import oracledb
TEST="'xxxx':'XXX'/'XXX'"
with oracledb.connect(user="xxx", password="xxx", dsn=TEST, disable_oob=True)

it return:

oracledb.exceptions.DatabaseError: DPY-4011: the database or network closed the connection

could you help me?

Answer 1

This will usually occur if you haven't enabled disable_oob.

If you have enabled disabled_oob=True, then please check your internet connection and try again.
