11G的 String url = "jdbc.url=jdbc:oracle:thin:@(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.9.*)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.9.*)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)))";
10G的 String url = "jdbc:oracle:thin:@192.168.9.*:1521:orcl";
資料庫從10G升級到11G，資料庫就連線不上了。先前以為是rac的寫法上的不同原因，但是一直沒有解決，最後硬著頭皮看jar包程式碼，最後發現問題在jar包裡面。再看看jar包裡面MANIFEST.MF,裡面顯示的Specification-Version: "Oracle JDBC Driver version - 9.0.2.0.0"，於是下載個搞版本的ojdbc14 ，MANIFEST.MF檔案顯示的Specification-Version: Oracle JDBC Driver version - "10.2.0.5.0"。連線成功。
