We are implementing an application hosted on a web application server. In production, many (thousands) of concurrent users will access the system.

By setting a trace ...

4. Session-per-conversion or Session-per-request?    forum.hibernate.org

Which approach do you prefer for implementing long application transactions? I have used Session-per-request with detached objects extensively, and find it a natural and easy way to work.

To do that, I must submit a query like "ALTER SESSION SET NLS_COMP=...." How can I do this (perhaps in hibernate.cfg) ? Thanks a lot

9. When is session-per-request preferred and when a hindrance?    forum.hibernate.org

So I''m trying to fix a problem caused by the need to use select-before-update in an application because the persistence wrapper around hibernate attempts to hide the session and transaction such that when using the session-per-request pattern every invocation of a database operation opens a new session and at the end of every database operation in a finally block closes the ...
