Hi all,
We have 4 Jboss AS which are load-balanced via Apache Http Server with mod_=
jk 1.2.28.
If a request from client comes, this will be forward to one of the JBoss in=
stance assumed JB1. A session is built and began in JB1 with a session-id. =
All the requests and responses after that will be kept in this session till=
the client close it.
But sometimes the connection btw. Apache and JB1 is brocken and if a reques=
t comes the Apache send this to another JB-instance assumed JB3. Since the =
session-id is not began by JB3, therefore JB3 throws an exception in the se=
rver.log "NoSuchConversationException". One can find the session-id which b=
egan in Jb1 in Jb3 server.log.
I am not sure if our parameters in workers.properties are correct? Or shoul=
d we use additionally clustering in Jboss.
Regards
Thomas
The parameters in the workers.properties look as follow:
....
