    Insuffient privilages


      Hi all,


           I installed 11g in my system.Then I used to login as username@admin/password.It returns error as ORA-12154: TNS:could not resolve the connect identifier specified.


      After that I tried sqlplus "/ as sysdba" it returns as ORA-01031: insufficient privileges and then i set ORACLE_SID and then try sqlplus "/ as sysdba" it returns ORA-12560: TNS:protocol adapter

      error.  How to resolve this problem??
