今天一同事問到了我這個問題，由於本人對Weblogic不太瞭解，所以決定先嚐試一下。
新建一個數據源，通過傳統的Jconsole連接（需要在Weblogic啓動參數中配置jmx參數，這裏省略），在MBean一欄中 沒有找到關於JDBC資源的監控項。
通過查找資料，發現可以通過IIOP訪問，步驟如下：
1、在${WLS_HOME}/lib下面執行 java -jar wljarbuilder.jar，生成wlfullclient.jar，拷貝到${WLS_HOME}/ext目錄，重啓。
2、控制檯，域-安全-一般信息，選用“啓用匿名管理員查找“，否則沒有查找權限，重啓。
權限錯誤如下：

3、控制檯，服務器-協議-IIOP，啓用IIOP，默認IIOP用戶名和默認IIOP口令改成和管理員一樣！否則一直會有權限錯誤。重啓。
權限錯誤如下：
<Warning> <RMI> <BEA-080003> <RuntimeException thrown by rmi server: weblogic.corba.cos.naming.RootNamingContextImpl.resolve([Lorg.omg.CosNaming.NameComponent;)

4、把${WLS_HOME}/lib下的weblogic.jar和wlfullclient.jar拷貝到D:/weblogic目錄。
5、cmd執行
jconsole -J-Djava.class.path=“%JAVA_HOME%/lib/jconsole.jar;%JAVA_HOME%/lib/tools.jar;D:/weblogic/wlfulclient.jar; D:/weblogic/weblogic.jar“ -J-Djmx.remote.protocol.provider.pkgs=weblogic.management.remote
6、彈出Jconsole客戶端，遠程進程輸入“service:jmx:rmi:///jndi/iiop://${WEBLOGIC_IP}:${WEBLOGIC_PORT}/weblogic.management.mbeanservers.runtime”，用戶名和密碼輸入管理員用戶名和密碼，這裏是默認的weblogic和weblogic。
7、連接，切換到Mbean頁面。查看JDBC連接信息如下。在這個頁面可以動態監測JDBC連接池的連接個數變化。
