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";

数据库从10G升级到11G，数据库就连接不上了。先前以为是rac的写法上的不同原因，但是一直没有解决，最后硬着头皮看jar包代码，最后发现问题在jar包里面。再看看jar包里面MANIFEST.MF,里面显示的Specification-Version: "Oracle JDBC Driver version - 9.0.2.0.0"，于是下载个搞版本的ojdbc14 ，MANIFEST.MF文件显示的Specification-Version: Oracle JDBC Driver version
- "10.2.0.5.0"。连接成功。
