Hi All,

we have two applications A1 & A2 both are accesing the same databse table employee at the same time.
How can i manage this so that both application can get the correct no of emloyee while A1 is inserting a employee
at the same time while other applicatuion is getting the empployee list?
I can i maintain a session between these two applications.

Thanks
Chiranjeevi

That is what transaction isolation levels are for. Any level other than READ_UNCOMMITTED should do it.

Is your code in a standalone Java app, or is it deployed to an app server? If the latter, are you using persistence? If so, all this is handled for you. If not, then you will have to commit the transactions yourself.

Are you using an ORM such as Hibernate? That could also change things a bit.
