Database Reader java.sql.SQLException

KNIME Analytics Platform
1

Hi,

using knime 2.3.0, I'm able to connect to oracle DB (database driver ojdbc14.jar) with the following settings in the Database Reader:

Database driver: oracle.jdbc.driver.OracleDriver

Database URL: jdbc:oracle:thin:@svrmdlpr:1521:stchem

In the same linux PC, using the new versions of knime (2.3.4 and 2.4) and the same database driver and settings, I obtain this message

WARN      Database Reader     java.sql.SQLException: java.util.concurrent.TimeoutException

and I can not connect to the oracle DB.

Has anyone some suggestions?

Do you still have KNIME 2.3.4 running (in parallel to 2.4) and it fails only for 2.4 using the same driver file, can you please confirm. The error shows that the problem already occurs when KNIME tries to establish the connection to the DB, so it could be related to network problems...?
