...

说明：通过在RAC中新增四个监听服务，来实现通过不同服务名连接到不同的实例。

1.查看并使用srvctl来增加服务名

[Oracle@bysrac1 ~]$ crs_stat -t
-bash: crs_stat: command not found
[oracle@bysrac1 ~]$ su - grid

使用srvctl向监听中增加 jiaoyi ，fengkong，caiwu，jiesuan四个服务--要用ORACLE用户

[grid@bysrac1 ~]$ srvctl add service -d bysrac -s jiaoyi -r "bysrac1"
PRCD-1026 : Failed to create service jiaoyi for database bysrac
PRKH-1014 : Current user grid is not the same as oracle owner oracle of oracle home /u01/app/oracle/product/11.2.0/dbhome_1.
[grid@bysrac1 ~]$ exit
logout
[oracle@bysrac1 ~]$ srvctl add service -d bysrac -s jiaoyi -r "bysrac1"
[oracle@bysrac1 ~]$ srvctl add service -d bysrac -s fengkong -r "bysrac2"
[oracle@bysrac1 ~]$ srvctl add service -d bysrac -s caiwu -r "bysrac1"
[oracle@bysrac1 ~]$ srvctl add service -d bysrac -s jiesuan -r "bysrac2"
[oracle@bysrac1 ~]$ su - grid
Password:
[grid@bysrac1 ~]$ crs_stat -t 可以看到新增的四个服务已经存在，但还是OFFLINE状态。
