Oracle 版本:11.2.0.4.0,初次安装,很多不懂,请大佬解惑。
首次安装好 Oracle 后,使用 lsnrctl status 查看监听和实例,正常。
Service "orcl" has 1 instance(s).
Instance "orcl", status READY, has 1 handler(s) for this service...
The command completed successfully
后来我本机变更了 IP 地址和主机名,已改 hosts 表。通过 netmgr 这个工具修改了监听信息,发现实例无法启动,lsnrctl status 显示 The listener supports no services,接着参考网上帖子,手动修改了 listener.ora ,实例可以启动了,但状态变成了 UNKNOWN,lsnrctl status 如下:
Service "orcl" has 1 instance(s).
Instance "orcl", status UNKNOWN, has 1 handler(s) for this service...
The command completed successfully
继续参考别的帖子,尝试了强制注册,手动注册等等方法,lsnrctl status 最终变成了如下:
Service "orcl" has 2 instance(s).
Instance "orcl", status UNKNOWN, has 1 handler(s) for this service...
Instance "orcl", status READY, has 1 handler(s) for this service...
The command completed successfully
请问这个 UNKNOWN 和 READY 两种状态同时存在,是异常吗,应该如何解决?
