Oracle RAC 集群配置

配置别名:

RAC_DB =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = node1)(PORT = 1521))

(ADDRESS = (PROTOCOL = TCP)(HOST = node2)(PORT = 1521))

(LOAD_BALANCE = yes)

(FAILOVER = on)

)

(CONNECT_DATA =

(SERVICE_NAME = RAC_DB)

(FAILOVER_MODE = (TYPE = SELECT)

(METHOD = BASIC)

(RETRIES = 20)

(DELAY = 10)

)

)

)

JDBC：

String userid = "scott";

String password = "tiger";

String tnsnames_info =

"(DESCRIPTION=(ADDRESS_LIST=" +

"(ADDRESS=(PROTOCOL=TCP)(HOST=node1)(PORT=1521))" +

String url = "jdbc:oracle:thin:@" + tnsnames_info;

DriverManager.registerDriver(new oracle.jdbc.OracleDriver());

Connection dbConnection = DriverManager.getConnection(url, userid, password);
