JDBC连接oracle RAC数据库配置
配置过程，找到tnsname.ora，查看对应的sid的description，为
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = werprac3-vip.ttmtech.com.hk)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = werprac1-vip.ttmtech.com.hk)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = werprac2-vip.ttmtech.com.hk)(PORT = 1521))
)
(LOAD_BALANCE = YES)
(FAILOVER = ON)
(CONNECT_DATA =
(SERVICE_NAME = PRD1)
)
)
java连接RAC:
public static Connection getConnForOracleLive(String username,String password) throws Exception{//驱动名String driverName = "oracle.jdbc.driver.OracleDriver";//连接服务器和数据库名String url = "jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=werprac3-vip.ttmtech.com.hk)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=172.30.254.36)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=werprac1-vip.ttmtech.com.hk)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=172.30.254.38)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=werprac2-vip.ttmtech.com.hk)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=172.30.254.37)(PORT=1521)))(LOAD_BALANCE=YES)(FAILOVER=ON)(CONNECT_DATA=(SERVICE_NAME=PRD1)))";Connection conn = null;//加载驱动Class.forName(driverName);//获取连接conn = DriverManager.getConnection(url, username, password);System.out.println("获取oracleLive连接成功！");return conn;}}
