重启数据库是出现了不能识别的实例

scottify

重启数据库
我先其监听结果如下：

% lsnrctl start

在最后出现的Service 中实例都为  UNKNOWN 状态是否正常？

然后我sqlplus /nolog

connect sys/* as sysdba

出现如下结果:

SQL> connect sys/sysexp as sysdba
Connected to an idle instance.

请大家给我看下

numenhuang

1. listener出现的unknown是正常的，因为是静态注册的Service

2. SQL> connect sys/sysexp as sysdba
Connected to an idle instance.
意味着数据库没有启动
