Oracle 11gR2

Hi,

I installed Oracle 11gR2 server in my machine. OS is Windows 2008 64 bit server.

I am the administrator of the machine and also included in ora_dba group.

But when I try to login in the same machine where server is installed as "sqlplus / as sysdba" its giving error like

ora-12560 TNS Protocol adapter error.

I started oracle services in the machine also.

I set ORACLE_SID also as there in tnsnames. ora at the command prompt.

Still am getting the error. What else I can check?

Can you please suggest all the possible options to avoid this error and get connected to idle instance?

Thanks.

Can you use the relevant IP of the machine, as the hostname in TNS?

1. Run lsnrctl in database BIN folder
2. Then run
services your_sid_name

Can you show me the details of your Listener.ora file?

Since you are on the local machine, I do not believe this has anything to do with the listener.  You should be doing a BEQUETH connection so the listener isn't involved.

>>I set ORACLE_SID also as there in tnsnames. ora

Forget about the tnsnames.ora file for now.

If your database name is ORCL:
Make sure the Windows Service, OracleServiceORCL is started.
From a command prompt:  
set ORACLE_SID=ORCL
sqlplus / as sysdba

replace ORCL with whatever the database is named.
