Tuning Remote Communication

Use

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.

Activities

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.
