Hi,
I am using Jboss 4.0.2 and encountering the same No ManagedConnections exception after the blocking timeout which I believe leads to Transaction Timeout and Transaction Rollback exception -
Conn-pool configurations are
Min-pool-Size = 10
Max-pool-Size = 80
Blocking timeout = 30000 ms
stateless session bean configurations are as follows :
Max Bean instance pool size = 80
There does not seem to be any connection leaks in the application.
I have also tried adding strictMaximumSize in the session beans dd so as to restrict the concurrent beans accessing the connection pool but that does not solve the problem.
The expected load on application is somewhere around 300 concurrent threads (atmost).
Will altering of Basic Thread pool configurations help?
Are there any other configurations which I might be missing or have misconfigured?
Awaiting reply???
Regards,
sauser
