Hibernate version:3.0


We are experiencing intermittent problems with saving data. Our application reports a successful save but when checked, the data is not saved to the database. No exceptions are thrown. We try again it may work. Our production environment is a cluster with multiple managed servers. Our application is deployed to each managed server across mulitiple servers so our application is not actually clustered. The following is in the Hibernate configuration file:






We don't seem to experience this anomaly on our development environment. We develop from PC running a single Weblogic server in development mode and the development or test server is a cluster with 2 managed servers on a single server. I am thinking that perhaps the Weblogic clustering across multiple physical servers may be causing a problem but I am not sure and want to rule out any Hibernate configuration issues we may have.

Any ideas?

Thanks in advance.

just a thought here, but if you are saving your session objects between requests, and then at certain points in your logic committing your session, then this might be the reason for the intermitant and inconsistent saving... probably a rudimentary check of making sure that you are using a session-per-request and that all transactions are committed would be the first step... but you probably already did this... ;)

Actually we don't attempt to save any data until the user explicitly clicks the Save Data button. When clicked all data is saved at one time in a transaction, the session flushed and then closed.
