关于Oracle9i RAC客户端连接的问题，在线等待。。。
环境：Solaruis9＋Oracle9i RAC

Oracle9i RAC安装完毕，在客户端连接时，有时会报ORA-12545的错误，请教可能是什么原因造成的！

显然是没有配置通嘛，唉，tnsping 或者直接 telnet host 1521(或指定端口）看看

你到你的 RAC 机器上找到 tnsname.ora 文件，按照那个配就应该没有问题，但是前提要有 dns 或在本机 hosts 文件中配置数据库主机 ip

例子：
GRID =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = rac-vip1)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = rac-vip2)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = rac-vip3)(PORT = 1521))
    (LOAD_BALANCE = yes)
    (FAILOVER = ON)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = grid.zygl.com)
      (FAILOVER_MODE = (TYPE=SELECT) (METHOD=BASIC) (RETRIES=12) (DELAY=5))
    )
  )

我tnsping rac一切正常

客户端的tnsname.ora 配置如下：
####################################
# Date..........: Thu Jun 17 12:50:38 CST 2004
####################################

RAC =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.138.55.5(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.138.55.59)(PORT = 1521))
(LOAD_BALANCE = yes)
)
(CONNECT_DATA =
(SERVICE_NAME = rac)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
)
)
)

问题解决原来与dns有关系
