The J2EE Engine supports two protocols for remote communication:
· IIOP – a standard protocol used for interoperability between CORBA and Java objects
· P4 – an SAP-specific protocol for communication between Java remote objects
The following recommendations may improve the performance of the system when the application uses these protocols.
Since a single connection is established from a P4 client that runs in a separate JVM to the J2EE Engine, to achieve good performance you can:
· Configure the connections manipulation mechanism in a mode that is suitable for fewer client connections.
· Set bigger socket buffer sizes by maintaining the properties SO_RCVBUF and SO_SNDBUF of the Ports Manager on the J2EE dispatcher. For more information, see Ports Management.
The same recommendations apply to the use of RMI-IIOP.
