DG-dispatcher ‘D000’ encountered error getting listening address

DG 的备库一直报错:

ound dead dispatcher 'D000', pid = (29, 89)

其实这个是在网络解析上出现问题

[oracle@lps admin]$ cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.94.181 test primary
172.16.94.184 test standby

这里我是利用172.16.94.184 test standby 这套老数据库进行克隆的,所以解析不了。

[oracle@lps admin]$ cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
172.16.94.181 test primary
172.16.94.187 lps standby

修改后重启数据库无报错
