A question for implementing repeatable reads

[Dhiren Joshi]

Hi everyone,
I have a question on a transaction handling by EJBs' .
I have a hotel reservation to be done.
Customer selects the hotel he wants to stay in. The issue I am facing is that while the customer is doing reservation for one hotel room I have to block any updates to the hotel for that chain of hotels else the rooms available will go out of synch. What transaction handling do I implement here
Any one please give me some suggestions.
Thanks

Hi ,
The confusion was coming becuase I was implementing a repeatable read block even for querying the rooms available. I figured the transaction context needs to be applied only when an update is done.
If another customer comes in while another is browsing the availability of rooms ,then its unfair to block the other customer from booking.
This is how I coded it and it seems that concurrent users can have access to reserve but in this case the first one gets it done. Any way I will let the client worry about it if my implementation is right or wrong. And they can request for the changes, For now this is how I implemented it .
Any ideas.

Hi Dhiren,
As for this thread it looks like the Oracle forum is a more appropriate place for the topic.
