JDBC logging to file

Question

I need to log all the queries to an Oracle database in my project to a log file.

What would be a good solution to achieve this? Some sample usage would be a

Answer 1

I'm measuring the performance of my jdbc driver, this is a Tandem Non/Stop DB, and just setting the LogWriter in the DriverManager like this:

        try {
            // This will load the JDBC Driver
            Class.forName("com.tandem.t4jdbc.SQLMXDriver");
            // Here you will enable the Logging to a file.
            DriverManager.setLogWriter(new PrintWriter(new File("log/dbcLog.log")));
        } catch (ClassNotFoundException e) {
            _logger.error(e.toString());
        }

The logging on Queries started working.

Just as an update, I also found out that for some JDBC drivers the solution can NOT be accomplished programatically (by code changes). For example, I'm using a JDBC driver for Tandem t4 driver, and even though I added all what the manuals said about enabling JDBC tracing, it just worked from time to time and just for Queries..

Then, I was told to use just the following parameter (as a VM Option):

-Dt4sqlmx.T4LogFile=t4sqlmx.log -Dt4sqlmx.T4LogLevel=FINE

And it just simple started working..
