You can use the partitionning option. Load into a 1 partitionned table then do a partition exchange with the target table.
It allows you to have the current data live while loading into the partitionned table. Once the load is loaded just exchange the partition with the table, it is fast as it is just an update in the data dictionnary. No data is physically moved.

We load data from mainframe into the database every day. The following are the steps how we load data currently: 1. get the data file from Datacom 2. ftp the data file from mainframe to the Sun machine where the Oracle database resides 3. truncate all tables in Oracle database 4. load the data into Oracle with SQL LOADER Most tables in the Oracle database don't have primary key. Tables are not available during the loading that gives us problem for our 24x7 availability. Therefore, we would like to change our loading method. Any ideas would be highly appreciated.
