Re: Wicket in a wildfly cluster
Dear Ravi Please let me know the loading test result, cause I built identity provider with this cluster mode, and I have to check whether it exists the same problems.

Re: Wicket in a wildfly cluster
Hi Shengche, sorry for the late reply. The replication as such is working. We do run into what seems to be a timing factor. On a very small scale it works now with the pagestore on a shared filesystem. We'll do some loadtesting within the next days. -Ravi -- Sent from: http://apache-wicket.1842946.n4.nabble.com/Users-forum-f1842947.html - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Wicket in a wildfly cluster
Ravi Another question, does your apache https using mod_cluster package from jboss ? Or have you check the replication packets working status via port ? > On 5 Mar 2018, at 19:09, Ravi wrote: > > Hi, > > wildfly runs in domain mode with default settings for the distributed cache. > > It seems that the problem is not the jboss settings but somehow the > pagestore is either not written fast enough or concurrently. > > > > -- > Sent from: > http://apache-wicket.1842946.n4.nabble.com/Users-forum-f1842947.html > > - > To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org > For additional commands, e-mail: users-h...@wicket.apache.org > - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Wicket in a wildfly cluster
Hi, wildfly runs in domain mode with default settings for the distributed cache. It seems that the problem is not the jboss settings but somehow the pagestore is either not written fast enough or concurrently. -- Sent from: http://apache-wicket.1842946.n4.nabble.com/Users-forum-f1842947.html - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Wicket in a wildfly cluster
Hello Dose your wildfly runs at standalone mode ? or domain mode ? any adjustment of session replicating? I add boss-web.xml as flowing http://www.jboss.com/xml/ns/javaee"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation=" http://www.jboss.com/xml/ns/javaee http://www.jboss.org/j2ee/schema/jboss-web_5_1.xsd";> / SET_AND_GET SESSION > On 2 Mar 2018, at 22:05, Ravi wrote: > > We also tried to put the pagestore on a shared filesystem, with a similar > result. > The session itself is only a few kb. > > Thanks for taking the time! > > -- > Sent from: > http://apache-wicket.1842946.n4.nabble.com/Users-forum-f1842947.html > > - > To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org > For additional commands, e-mail: users-h...@wicket.apache.org >
Re: Wicket in a wildfly cluster
We also tried to put the pagestore on a shared filesystem, with a similar result. The session itself is only a few kb.

Re: Wicket in a wildfly cluster
Hi Ravi, Sorry - I have no experience with "real-time" session replication. Personally I would never attempt it, as wicket sessions can grow relatively large and thus replication may not be instantaneous (as you are experiencing)… Met vriendelijke groet, Kind regards, Bas Gooren Op 2 maart 2018 bij 14:40:50, Ravi (ravi.k...@intellinet.de) schreef: Hi Bas, we have an apache that balances by using a round robin (byrequest).

Re: Wicket in a wildfly cluster
Hi Ravi, You don’t mention what’s in front of your application servers. Are you doing non-sticky load balancing? Or are you having issues when the user hits the same application server? (Which would be a different issue) Met vriendelijke groet, Kind regards, Bas Gooren Op 2 maart 2018 bij 13:43:49, Ravi (ravi.k...@intellinet.de) schreef: Hi all, we have the following scenario; Our single-page application is a 100% used for application forms and makes heavy use of ajax calls (validation, visibility, etc).
