What is a Checkpoint in oracle?
A checkpoint performs the following three operations:Every dirty block in the buffer cache is written to the data files. That is, it synchronizes the datablocks in the buffer cache with the datafiles on disk. It's the DBWR that writes all modified databaseblocks back to the datafiles.The latest SCN is written (updated) into the datafile header.The latest SCN is also written to the controlfiles.The update of the datafile headers and the control files is done by the LGWR(CKPT if CKPT is enabled). As of version 8.0, CKPT is enabled by default.

What is sql loader?
SQL LOADER is an Oracle utility used to load data into table given a datafile which has the records that need to be loaded. SQL*Loader takes data file, as well as a control file, to insert data into the table. When a Control file is executed, it can create Three (3) files called a log file, bad file or reject file, discard file. * Log file tells you the state of the tables and indexes and the number of logical records already read from the input datafile. This information can be used to resume the load where it left off. * Bad file or reject file gives you the records that were rejected because of formatting errors or because they caused Oracle errors. * Discard filespecifies the records that do not meet any of the loading criteria like when any of the WHEN clauses specified in the control file. These records differ from rejected records.
