Rollback is only possible inside a transaction.

sorry i did not understand.. can u please explain.
I used ERRORS=0 as command line paramter for sql loader so that not data is loaded when a data error has occured. I am automating the script so that it loads from the begining the next time. I am not sure of how to avoid duplicate records being inserted. pls advice

Use a staging table, truncate it before loading. Once you get it right move the data from staging to final-destination table.
The "transaction" concept is at the foundation of rdbms technology, it wouldn't hurt to read a little about it.
