关于srvctl命令的理解
本帖最后由 wrx0815 于 2013-12-19 14:26 编辑关于srvctl命令，大多数人和我应够都只停留在命令的使用上，但在RAC环境下，它和直接对实例的操作有什么具体的区别呢？特想maclean请教一下。也是最近发现了一个现象。
我的测试环境是10.2.0.1，RAC和单点都是这样。
当我使用 srvctl 命令启动RAC端的监听时，在单点上通过 tnsnames 中的连接字符串却无法正常连接到数据库。我使用的是：
RACDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = rac2-vip)(PORT = 1521))
(FAILOVER=YES)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = RACDB)
)
)
报错提示 no listener，但我使用lsnrctl命令启动每个节点监听后，单点通过tnsnames却可以正常连接数据库，每次连接都成功。
我自己没想明白为什么，srvctl 命令执行的时候，到底做了哪些工作？ 你可以理解为 srvctl 做了组合拳， 具体如何组合的 你可以参考crsd.log Liu Maclean(刘相兵 发表于 2013-12-19 15:23 static/image/common/back.gif
