这里的Cluster name: rac-cluster
可以通过如下命令获取:
[grid@rac01 admin]$ cemutlo -n
rac-cluster
3.登陆
根据安装提示进行登陆
https://rac01:1158/em
客户端我们换成具体的ip进行访问
节点1上的三个ip都可以访问
https://节点1公共ip:1158/em
https://节点1vip:1158/em
下面这里我们是通过scan-ip进行访问的
3.2遇到的问题
问题1:
WARNING: Error during db connection : ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
解决办法:
在节点1上的grid账号登陆asm实例修改remote_listener参数
[grid@rac01 admin]$ sqlplus /nolog

NAME TYPE VALUE
------------------------------------ ---------------------- ------------------------------
remote_listener string rac-scan:1521
remote_login_passwordfile string EXCLUSIVE
remote_os_authent boolean FALSE
remote_os_roles boolean FALSE
问题2:
将已经锁住的账号进行解锁

问题3:
不知道为什么我安装好rac是没有配置em的，安装的时候提示已经安装,需要进行删除处理
Dec 17, 2020 3:53:03 AM oracle.sysman.emcp.DatabaseChecks performReposChecks
SEVERE: Dbcontrol Repository already exists. Fix the error(s) and run EM Configuration Assistant again in standalone mode.
解决办法:
$ emca -deconfig dbcontrol db -repos drop -cluster
cluster name获取
[grid@rac01 admin]$ cemutlo -n
rac-cluster
