I wanted to load data to remote db using sqlldr.I did it using following command

>sqlldr GANUKA/GANUKA@jdbc:oracle:thin:@172.21.0.180:1521:orcl control=D:\Work\CLSTMAS.ctl 
log=D:\Work\CLSTMAS.log

But it gives the following error.

SQL*Loader-704: Internal error: ulconnect: OCIServerAttach [0]
ORA-12154: TNS:could not resolve the connect identifier specified

Need a help
