Last updated on OCTOBER 04, 2023

Applies to:

Oracle WebLogic Server - Version 8.1 and later
Information in this document applies to any platform.


T3 is the protocol used for RMI communication with WebLogic server. T3S is the version of the protocol over SSL when secure communication is required. This document generally uses T3 for the protocol that includes both.

Take for an example where an EJB application is deployed on a WebLogic Cluster and a standalone client makes T3 calls to the EJB application deployed on WLS cluster. The standalone client connects to a load balancer address using T3 protocol and the load balancer distributes T3 calls to WebLogic Cluster. Below is a request flow to show the use case:

Standalone Java Client -> connects to H/W Loadbalancer using t3 protocol -> Load balancer proxies and load balances T3 calls to WebLogic Cluster (EJB application)
