[jboss-user] [Datasource Configuration] - Oracle Datasource: Unable to fill pool. OutOfMemoryException
Hello NG,
we develope our first project on JBoss, and so we are not very experienced. But for
several months we were very happy with JBoss where we also have a Oracle Datasource which
we use. So everythings fine,
BUT for 2-3 days now, we've got the following error. The ConnectionPool tell us that
he is unable to fill the Pool and the database is OutOfMemory. Other connections (outside
Jboss) to the database lead to the OutOfMemory-Error, too. Everytime we have to stop JBoss
to get the database work again.
Can anyone tell me what we've done wrong? What can I figure out or monitor inside
JBoss to discover the error(s)? Are there any suggestions or ideas?
Thanks a lot for any help!
Chris
