Where does the trace output go?
By default the trace output goes to System.out. You can send it elsewhere either with the property oracle.jdbc.LogFilejava -Doracle.jdbc.LogFile=/tmp/jdbc.log MyAppor by calling the setLogStream api.oracle.jdbc.driver.OracleLog.setLogStream(System.err);Setting the log stream starts the trace as well. You can turn the trace off by setting the log stream to null.
