Hi,

I have installed in oracle 10g in my machine. I did following step

1. set oracle_sid=orcl
2. sqlplus/nolog
3. startup

I got TNS:protocol adapter eeror. This happens even when listener is up. Could anyone please explain what is the cause and give solution?

Regards
Murali

If you are on Windows, then make sure the Window's Oracle service (ie. OracleService<oracle_sid>) is started.

Thanks ebrian, I was able to connect oracle after starting the Oracleservice<sid> service in windows.

After starting this service, the instance became up. Can anyone tell me when can we use startup command to start the oracle instance.

You can use the STARTUP/SHUTDOWN command once the OracleService<sid> is started. Issuing SHUTDOWN for the database will not actually stop the Windows service, therefore you can issue STARTUP to restart the database without having to restart the Windows service.

Hi Ebrian,

Thank you. I started oracleservice<sid> service in windows for a database. This service mounted the database and the instance was up. So I understand that there is no need to give startup when we start this service.

Is there anyway to start only the service and prevent the database instance getting mounted.

Regards
Murali

NO.

you have to manully shutdown your database.
and startup up nomount mode.



Actually, you can set the Windows service to NOT autostart the database when you start the Windows service itself. If you change the ORA_<sid>_AUTOSTART paramter in the registry to FALSE, then the database will not be started when you start the Windows service for that database.
