We have ORACLE 9iR2 on SUN server and 9iR2 application server on NT. Our developer compaint they insert lots of data from java through JDBC and 9iR2 application server to ORACLE database. after finish, they check table and NO data in it. They point finger to DB redo log or undo tablespace is wrong. I checked alert.log and there is NO error message.

The developer said "java is autocommit on execute query". My questions are:

1. does anyone know how java auto commit work? Does it commit after evry insert or after 100 insert?
2. if java connection broke, will oracle rollbak those insert data?
3. any ideal why data gone?

Thanks.
