> This FAQ (http://www.hibernate.org/120.html#A6) regarding batch updates should be disabled against DB2 is incorrect. Batch update works fine when using IBM DB2 JDBC driver shipped with version 8 and version 9. Batch updates should be enabled because it provides performance advantages to application using hibernate against DB2.
> In another thread (http://www.hibernate.org/120.741.html) it shows a stack trace with ClassCastException. This only happens if type changes between batch elements. This can be avoided by setting connection property deferPrepares to false. This bug was also fixed in the driver that was shipped in early 2006.
