yes, because you are not holding the transaction open while reading the LOB, so the LOB is disappearing while you are
reading it.
i.e.
connection.setAutoCommit(false);

Hi Noel,
The update thread and the read thread each have separate
transactions/connections(ThreadLocal) to the database.
So while the read thread is open, the update thread comes and

the column in CLOB.

I am getting exceptions stating "Missing lob entry" on concurrent update

I seemed to hit the error Missing lob entry quite frequently for my

Hi Thomas,
Thank you for the update. I would like to help the project implement
LOBs with MVTableEngine. I may need to get more familiar with the
project's source before I can add something to it.
As I am looking at the source, I see that the current documentation
about the LOB storage is
