Hi all,
I was using Knime 3.5 version and today I updated to version 3.6. With Knime 3.5 I was able to connect to an Oracle database with a database connector node. However, now with version 3.6 I am getting this error:
ERROR Database Connector 0:49 Execute failed: Could not create a connection to the database: Maximum number of retries to get a valid connection reached. JDBC URL: jdbc:oracle:thin:@jrorap001.journalrep.tio.systems:1521:jrprd
I am using class12.jar
Any suggestion on why I can’t connect to the database?
Thank you.
Paola
