2.启动Logging模式      第一种方式：设置执行环境变量java -Doracle.jdbc.Trace=true ...（elipse中run->run configurations->arguments一栏）      另外一种方式：在程序中控制（建议採用这样的方式）

MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
			String loader = Thread.currentThread().getContextClassLoader().toString().replaceAll("[,=:\"]+", "");
			ObjectName pattern = new ObjectName("com.oracle.jdbc:type=diagnosability,name=" + loader);
			ObjectName diag = ((ObjectName[]) (mbs.queryNames(pattern, null).toArray(new ObjectName[0])))[0];
			mbs.setAttribute(diag, new Attribute("LoggingEnabled", true));
			System.out.println("LoggingEnabled = " + mbs.getAttribute(diag, "LoggingEnabled"));
			

/**oracle 10g 启动方法*/
			oracle.jdbc.driver.OracleLog.setTrace(true); // enable logging
			oracle.jdbc.driver.OracleLog.setTrace(false); // disable logging

	/**配置log文件*/
			Handler fh = new FileHandler("./oracle_jdbc_log.log");
			fh.setLevel(Level.ALL);
			fh.setFormatter(new SimpleFormatter());
			Logger.getLogger("").addHandler(fh);
			Logger.getLogger("").setLevel(Level.ALL);
