Go it! And I will use plain JDBC. Thanks a lot for all your inputs!

Using JDBC/iBATIS for bulk data loads will usually be slower than using your database's bulk load utility. See this page from postgresql dicumentation for more information: http://www.postgresql.org/docs/8.1/interactive/populate.html If you feel you must use iBATIS, then I'd recommend using a batch and issuing periodic commits. See the iBATIS developer's guide (page 56) for an example. But, this will likely be much slower than using the bulk loader.

May I know how ibatis deal with big chunk of data please? The example I had is the following, would you suggest better solution? (1)Transaction begins (2) select from oracle.table1 into object1 . possible solution is to split table1 into table1_subgroupdata1, ...n (3) for loop object1 => insert into postgreSQL (4) if success commit else rollback (5) Transaction ends Thanks a lot! -- View this message in context: http://www.nabble.com/ibatis%2Bspringframework-for-millions-data-loading-tp18592540p18592540.html Sent from the iBATIS - User - Java mailing list archive at Nabble.com.
