You can use bulk loading to improve the performance of a session that inserts a large amount of data into a DB2, Sybase ASE, Oracle, or Microsoft SQL Server database. Configure bulk loading in the session properties.
When bulk loading, the Integration Service bypasses the database log, which speeds performance. Without writing to the database log, however, the target database cannot perform rollback. As a result, you may not be able to perform recovery. When you use bulk loading, weigh the importance of improved session performance against the ability to recover an incomplete session.
When bulk loading to Microsoft SQL Server or Oracle targets, define a large commit interval to increase performance. Microsoft SQL Server and Oracle start a new bulk load transaction after each commit. Increasing the commit interval reduces the number of bulk load transactions, which increases performance.
