After all done mendentory to close all operation cursor.close() con.close() Creting table: filter_none. play_arrow. try: connection = cx_Oracle.connect (username,password,databaseName) except cx_Oracle.DatabaseError, exception: printf ('Failed to connect to %s\n',databaseName) printException (exception) exit (1) The connection should be closed when no longer required using: connection.close () # This script demonstrates the use of connection pooling in cx_Oracle. link brightness_4 Internal features help protect against # dead connections, and also aid use of Oracle Database features such as FAN # and Application Continuity. After some analysis the cause seems to be the invokation to cx_Oracle.Connection.close(). Step 3: Connect Python to Oracle using cx_Oracle connect. The user, password and dsn parameters are the same as for cx_Oracle.connect() The min, max and increment parameters control pool growth behavior. ... cx_Oracle will automatically close the cursor and release the connection back to the pool for reuse. Pools # can significantly reduce connection times for long running applications that # repeatedly open and close connections. Then del is called, network connections are illustrated again.

To add an additional column you'll need to add , '-', row[2], etc. This is an excerpt of the logger: For communicating any database with our Python program, then we required some connector which is nothing but the cx_Oracle module. this seems like something that could really easily be part of cx_Oracle, enabled by a flag on connect "auto-clean cursors", or if I could register event hooks to do this, it seems like there's a Subscription system now but it's not clear that it works for this. This allows cx_Oracle applications to support features like Application Continuity. The script creates one connection, closes it, illustrates what network connections are set up to port 1521. The completion of function execution takes almost all the 15 minutes. This is cx_Oracle 5.1, script is tested on Mac OSX as well as Fedora 14. Ex.
