After some analysis the cause seems to be the invokation to cx_Oracle.Connection.close(). import cx_Oracle; connect(): Now Establish a connection between Python program and Oracle database by using connect() function. Then del is called, network connections are illustrated again. Finally, ... To add an additional column you'll need to add , '-', row[2], etc. Internal features help protect against # dead connections, and also aid use of Oracle Database features such as FAN # and Application Continuity. ...
