配置Oracle 10g RAC为客户端LOADBALANCE+FAILOVER模式

cd /u01/app/oracle/product/10.2.0/db_1/network/admin

 

vim tnsnames.ora

服务名如下：

BDATA =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = c1-vip)(PORT = 1521))

    (ADDRESS = (PROTOCOL = TCP)(HOST = c2-vip)(PORT = 1521))

    (ADDRESS = (PROTOCOL = TCP)(HOST = c3-vip)(PORT = 1521))

    (LOAD_BALANCE = yes)

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = bdata)

      (FAILOVER_MODE =

        (TYPE = session)

        (METHOD = basic)

        (RETRIES = 180)

        (DELAY = 5)

      )

    )

  )

保存退出

 

sqlplus /nolog

反复执行：

connect sys/xxxx@bdata as sysdba;

select instance_name from v$instance;

如果出现三个不同的实例轮换（c1-vip, c2-vip, c3-vip各自的实例），那就是配置成功了。
