System, method, computer program for fast bulk loading data into database while bypassing exit routines. Method for bulk loading of data into database tables with exit routines defined for operations on such tables, method characterized by existence of exit routines is by-passed by performing data preprocessing in batch mode before loading; and loading preprocessed data into database by performing operations on lower level of tablespace and index spaces where database tables reside and not on database tables themselves. Method for bulk loading data into database tables with exit routines defined for operations on such tables comprising: batch processing data that requires processing to generate processed data; switching tablespace and related index spaces to stop mode; marking required space map entries used; loading previously processed data into claimed data pages; updating database index pages; resetting consistency tokens in updated page; and switching the tablespace and related index spaces to start mode. |
