在配置goldengate的时候，我们需要连接asm实例，，配置方法如下：
oracle 10g rac的方法：
在本地rac两个节点上listener.ora文件中添加：
rac1节点：
(sid_desc =
     (global_name = asm)
     (oracle_home = /oracle/app/product/10.2.0/db_1)
     (sid_name = +asm1)
    )
)
rac2节点：
(sid_desc =
     (global_name = asm)
     (oracle_home = /oracle/app/product/10.2.0/db_1)
     (sid_name = +asm2)
    )
)
在本地rac两个节点和远程客户端的tnsnames.ora文件中添加：
asm2 =
  (description =
    (address = (protocol = tcp)(host = 192.168.10.12)(port = 1521))
    (connect_data =
      (server = dedicated)
      (service_name = asm)
      (instance_name = +asm2)
      (ur = a)
    )
  )
asm1 =
  (description =
    (address = (protocol = tcp)(host = 192.168.10.11)(port = 1521))
    (connect_data =
      (server = dedicated)
      (service_name = asm)
      (instance_name = +asm1)
      (ur = a)
    )
  )
然后重启监听，远程测试连接：
[oracle@target ~]$ sqlplus /as sysdba
