1. Prepare the environment
We performed the test in Oracle 10g + Windows Server 2008. Note that multiple databases are created on the server. Therefore, you must specify the service name for logon.

3. Trouble-shooting
The root cause of this error is that the instance registration information is no longer available in the listener. It may be related to multiple databases, so I tried to specify ORACLE_SID to Solve the Problem smoothly.

C: \ Users \ Administrator>

C: \ Users \ Administrator> set ORACLE_SID = HOEGH

C: \ Users \ Administrator> sqlplus/as sysdba

4. Summary
The root cause of this error is that the instance registration information is no longer available in the listener. I specified ORACLE_SID to provide the instance information and solved the problem smoothly; the above content is just to provide you with a solution to the problem. I think there are other solutions on the Internet. It may be that the fault scenarios are different. You can refer to it when solving similar problems, including:
1. Restart the listener;
2. Restart sqlplus;
3. log on to the server and restart the database;
