Last updated on DECEMBER 16, 2023

Applies to:

Oracle WebLogic Server - Version to [Release 12c]
Information in this document applies to any platform.


A T3 load balancing issue was observed in WebLogic Server 12.1.2.  In an environment with many EJB Clients using replica aware stubs to connect to an EJB, the following was observed:

1. When all the managed servers are started at same time load is evenly distributed.
2. When one server or some servers are started, then the load is unevenly distributed.

After restarting a server, over a short period of time almost all of the load will go to the server that had been restarted.
