EAServer 5.5 IIOP Connections vs EAServer 5.2
We just upgrade from EAServer 5.2 to 5.5. We are noticing different behavior with the iiop sessions. We are running the same code on both versions. Basically we only have stateless session beans deployed to EAServer. With 5.2 the number of iiop sessions never goes above 2. However with version 5.5 the number of iiop sessions grows quickly until it hits the max of 20 (I guess the developer version limit was changed from 5 to 20). Does anyone know if version 5.5 of EAServer change the way it manages the iiop connections? When are these connections released? Any information about the iiop connections in 5.5 would be great. Thanks

Clients open IIOP connections, and clients close them.
The server NEVER forcibly closes an IIOP connection, it waits
for the client to do it.
So if you are seeing more connections, check your client(s).
You can use:
netstat -a
to check (from O/S) how many actual connections are active.

Thanks for the information about the client controlling the connection. But I have the same code deployed to 5.2 and 5.5 and also running the same test on both version. Why are the connections never going above 2 in 5.2 however with 5.5 we max out at 20 and get the out of connections error. Something had to change between version 5.2 and 5.5 for me to see this difference in the open iiop connections? Could a default property setting in 5.5 be set to something different which would cause me to see this different behavior? > Clients open IIOP connections, and clients close them. > > The server NEVER forcibly closes an IIOP connection, it > waits for the client to do it. > > So if you are seeing more connections, check your > client(s).
