jdbc 连接oracle rac 一会连接的上一会连接不上的问题？

Question

连接代码如下：
[color=blue]Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
String addrRAC = "(ADDRESS=(PROTOCOL=TCP)(HOST =10.0.5.62)(PORT =1521))(ADDRESS=(PROTOCOL=TCP)(HOST =10.0.5.60)(PORT =1521))";

String url = "jdbc:oracle:thin:@" + "(DESCRIPTION="
+ "(ADDRESS_LIST=" + addrRAC + ")" + "(CONNECT_DATA="
+ "(SERVER=DEDICATED)" + "(SERVICE_NAME=racdbs)" + ")"
+ ")";

Connection oracn = DriverManager.getConnection(url, "system","qz123456");[/color]

Answer 1

在应用服务器所在主机的host中配上到rac节点的ip映射即可。
