At this moment I have a problem with a connection to a DB AS400, my error says: "Error DB connector … Exception java.net.ConnectException: Error opening socket to server … connection reduced " Somebody can help me to solve this problem?
can you post your driver Configuration and Database Connection Node Configuration? (just hide the server address - however your connection url without the real ip would also be helpful in case there is something wrong )
That could help to identify the problem
Thank you for reaching out for assistance on the KNIME forums. If you are receiving a “connection refused” error, then it is at least attempting to make a connection. I recommend that you re-check your DB node configuration as suggested above to ensure that it is set up correctly.
If you still require assistance, please post the details of the driver configuration and node configuration (with any necessary information redacted) so that we can troubleshoot further.
