You can call getTransactionIsolation() on your Connection object.  That
will tell you the maximum level that the database supports.  I'm not
sure whether it is affected by the actuall journalling status of the
tables, though.

There's an AS400File object, with methods like
isCommitmentControlStarted(), that might be helpful.  That wouldn't be
database-independent, of course, but you could work around that with
spot of dynamic loading.

HTH.

Cheers,

Martin.
