when i use "Scott" "Tiger" it gives me ORA-12560: TNS:protocol adapter error occurred errorwhen i try to start service i get

LSNRCTL> start
Starting tnslsnr: please wait...

Failed to open service <OracleOraDb11g_home1TNSListener>, error 1060.
Failed to start service, error 203.
TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error

I am accessing the database from the same machine. Also do I need to have a ORACLE_HOME for getting sql plus working or it is not necessary?
