i use liferay6.5 clustered with none-sticky load-balancer and i store liferay session in JDBCStore
every thing work fine for me but my problem is i need to make static session ID created for each user
for example when user "test" log in to nod1 new session ID created and if the same user log in to Nod2 new session created so the session replication is losted between the two nods in the clustering, and this caused me problem if on node crashed so the user will log out from the portal
so how i can solve such thing

You have to enable <distributable/> in web.xml in Liferay. After that, rest of config should be changed in app server side (example: Tomcat) so that J2EE session gets replicated through all nodes.

i enable it from the first but it doesn't make any change ,,, new session create it

As I've said, now you have to config your server properly.

You have to enable <distributable/> in web.xml in Liferay.

could you provide me with more details about the rest config plz

Nop sorry, that isn't a Liferay question. There are many tutorials around there.
