ORA-12154 TNS:could not resolve service name : ORACLE BACKUP

I am littlebit sure about current Net Service Name (ENCORA), as when i am putting that I am getting "insufficient privileges" error,

while when I am putting "abcd or anything" it is giving "Database connection failed for OraServiceName ORA-12154 TNS:could not resolve service name" this error

My Database Admin told me that the username and password given to you is correct.

So what will be the reason for refusing my connection?

I am still not confirmed with the NET SERVICE NAME

Now I have changed the service name to ENCORA (I hope so it is right)

Now it is giving following error :

Database connection failed for ENCORA: ORA-01031 : insufficient privileges

I am not sure that it is right or not.

Well, Oracle says permissions are the issue. That means that your Oracle user for database or catalog (if used) do not have required permission (roles granted in Oracle language).

Is their any way to find out the current user is having which permissions?

So that I can drill down more...

Yes, you can do that in Oracle SQL. But simply leave that to Oracle guy - this is their part.

OK!

Hi,

You need to check if the service for the oracle instance you are trying to backup is running on the DB server. Also to take the oracle backup you could try to connect with RMAN using sys as:

connect target sys/password@DB_instance
{

Scritp
}

On Linux/Unix systems, Networker runs under the root account, check that root is part of the dba group.
Is this on a cluster ? are you using Oracle.NET ?
