I have experienced (and seen same problem in many forum topics) that Oracle Clob/Blob are not compatible with batch updates.
-> Oracle error = "streams type cannot be used in batching"

I am a little "upset" to have to disable the batch update mode in my whole application just because of a clob in one of my persistent classes :-(

Is there an alternative solution ?

I have noticed that a new new property (batch-size) has been introduced in the class mapping:


Does it mean that we can now disable batch updates for a single class :-) ?
=> not really clear to me: the doc says this property is used for fetching instances...

Thanks in advance.

If this is a major performance issue for you, you could use a secondary SessionFactory with batch-updates disabled for your LOB updates.

This is an Oracle shortcoming more than anything else, and there aren't any obvious workarounds that Hibernate could provide.
