I absolutely don't understand what specifying a table to reserve in
TPB means (don't even know what TPB is...)
Do I need that? :)

I'm a never draining well of questions:
Does transaction serializable throw an exception or waits until the
lock releases?
If it throws an exception, how can I tell from that exception (in
java), that it's not a consistensy error, just some transaction
isolation thingamijig?

Thank you Roman for helping,
