ORA-00106 cannot startup/shutdown database when connected to a dispatcher
问题信息：
Cause(原因): An attempt was made to start or shut down an instance while connected to a
shared server via a dispatcher.
Action(处理)： Reconnect as user INTERNAL without going through the dispatcher. For most
cases, this can be done by connect to INTERNAL without specifying a network connect
string.
大概意思是重新使用内部用户登录，而不要通过监听器调度程序(Dispatcher)来连接。
解决办法：
先退出 然后以SYSDBA权限连上数据库进行shutdown immediate;
