Memory use is very high in J2EE cluster with session replication (Weblogic)
when using pageflowscope
----------------------------------------------------------------------------------------------------
Key: TRINIDAD-1812
URL: https://issues.apache.org/jira/browse/TRINIDAD-1812
Project: MyFaces Trinidad
Issue Type: Bug
Components: Components
Affects Versions: 1.2.7-core
Environment: Weblogic 10 and all versions forward.
Reporter: Nicolai Marck Ødum
Priority: Critical
In a Weblogic cluster with session replication the memory use (the size of the
web session) is much higher on the server that has a copy of the session then
on the primary server.
The problem is related to multiple session attributes that have references to
the same shared object in Trinidad. This design has a negative side effect with
Weblogic because of the transitive closure ff session attributes. The shared
object (and the object graph below it) is copied for each attribute.
I have created a simple guide with a modified example of the demo application
from Trinidad that shows the problem.
