Unable to login in sql plus 11.2.0.3 without using SID

Hi,
I am unable to login in to sqlplus without using the DB parameter
ie if I login workgroup_test@WGS_Db it works
but if i login using just workgroup_test . it fails

I am getting the following error
ORA-12545: Connect failed because target host or object does not exist

My current set up is of Oracle 11g on RHEL 5 64 bit .

I checked almost everything to work
ie started the listener , checked tnsping , changed host name in tnsnames.ora by using the ip
But still am faciing the same issue

Kindly help.
