Hi to all,
This is a very commom topic in this forums and i've read a lot of posts on this matter, but unfortunately i did not find any precise answers.
I have installed the Jboss 2.4.9 and have a bean which accesses a Oracle database.
The jboss creates a pool of connections to the database and the bean works very well. The problem resides when there is a connection failure with the database because of server crash, network failure or something similar.
The pool created by jboss becomes invalid and it is not detected by it.
When i start again Oracle and start a client to access my bean an error occurs and the log file presents the following error:
Error: java.lang.RuntimeException: No ManagedConnections Available !
My questions are:
1. How to detect a lack of db connection and make a flush in the db pool?
2. More simple, just how to order a complete flush in a pool ?
3. I suppose this jboss distro does not support well this type of situations (for what i've read). Even tho, how could i change jboss source code to implement this type of feature? And in what .java files?
4. Which are the source java files that manage the connections pool ?
5. Is there a way to integrate the jboss 3.2 pool manager in the jboss 2.4 ?
It might be more simple to upgrade to the new version 3.2 but iam in a situation where we must use the 2.4 distro.
Thanks to all in advance
