[Clustering/JBoss] - Re: sticky_session=0 + UseJk=false + HTTP Session Replicatio

by Hellaenergy

I'd like to clarify that I have a hardware LB in front of two separate Apache + mod_jk (configured to load balance) nodes. Each Apache + mod_jk node lb's to the same two JBoss AS servers. If the HW LB cluster in front of the Apache nodes decides to send a request to a node other than the originating Apache + mod_jk sticky session initiating node (we'll call this ws node 1) during an active session then my assumption is the other Apache + mod_jk node (ws node 2) will have no knowledge or ability to handle the other Apache + mod_jk lb nodes activities/ sticky session? Thus my reason for skipping the sticky sessions. Follow me? The one thing they do have going for them is that they are both configured identically mod_jk wise. The workers are defined the same so therefore the jvmRoute entries theoretically could be identified by ws node 2 if ws node 1 wasn't available. I guess this brings me to another question. Does mod_jk keep track of sticky sessions it's initiated locally? How is that information stored/shared? If there are two separate web servers with mod_jk identically configured to LB w/ sticky_session=true and sharing the same workers, could one entire web server fail and the other take over seamlessly? How would JBossAS handle this. How would mod_jk handle this?

[Installation, Configuration & DEPLOYMENT] - Re: Failed shutdown attempt

by PeterJ

I have never seen an "Address already in use" error when attempting to connect to a port as a client (as a server, yes, but never as a client). Use netstat to determine if the port is open. Also try running: telnet localhost 1099 that should give you some gibberish as the output, but the key information is the hostname in that output - it could point to an issue in /etc/hosts. (I know there are several posts that discuss using telnet to debug this, but search doesn't yield any of them, so I can't point one out. So, could you post the telnet output and /etc/hosts file?)

[JBoss Portal] - "Links to resources within this portal should be absolute."

by Shi Yusen

While localizing JBoss Portal to Chinese, I'm curious on the CMS_LINK_TO_RESOURCES. "Links to resources within this portal should be absolute. For example: A link to an image located in default/images/back.gif should be typed in exactly as shown here. Do not prefix a slash (/) to the path of the resource. You can verify the link is correct by clicking on the preview button in the editor". I think it's a relative link, right? Shi Yusen/Beijing Langhua Ltd.

[Clustering/JBoss] - Re: sticky_session=0 + UseJk=false + HTTP Session Replicatio

by bstansberry＠jboss.com

Mod_jk with sticky sessions routes requests based on the jvmRoute appended to the session id in the session cookie. The failure of one of your Apache nodes does not mean sticky sessions won't work, since such a failure doesn't affect the session cookies. For more on the sticky session recommendation see http://www.jboss.org/community/wiki/WebClusteringBestPractices. Not sure what you're referring to when you discuss JAAS replication. Perhaps https://jira.jboss.org/jira/browse/JBAS-1900 ?? That's another reason to use sticky sessions -- the web container's FORM authentication mechanism assumes the post of the login form will go to the server that issued the form. Re: UseJK=true and a jvmRoute when sticky session aren't used, it's valid in the sense that it doesn't break anything. The UseJK=true isn't doing anything for you; adds a bit of overhead. I'm not going to comment beyond what I already have on not setting the jvmRoute as it's not something I've really investigated.

[Clustering/JBoss] - Re: sticky_session=0 + UseJk=false + HTTP Session Replicatio

by Hellaenergy

The reason I've chosen not to use sticky sessions is because theoretically at any time a node in the HW LB cluster could go down. If it does and the user gets directed to a different Apache + mod_jk node in the cluster what good is the sticky session then? I figure as long as session replication is turned on within my JBoss cluster I should be taken care of regardless if the originating HW or Soft LB node goes down. With UseJK set to false it's been reported to me that JAAS replication wasn't happening as it should. I can neither confirm or deny that report because I have not seen the evidence to back it up. However, I am wondering if there is any possible way that could be true? Also, if UseJK is set to true and jvmRoute is defined and mod_jk is still configured with sticky_session=0 is that ever a valid configuration?

[EJB 3.0] - Re: onetomany relationship question

by Wolfgang Knauf

Hi, I played around with your sample a bit. I agree that it works if you first create and save the parent, then create the child, set the parent and persist the child. But assume that you don't save the parent, but the child. Here is the code snippet: ParentBean parent = new ParentBean(); | entityManager.persist(parent); | | | ChildBean child1 = new ChildBean(); | parent.getChilds().add(child1); | //child1.setParent(parentNew); | | entityManager.persist(parent) | In this case, child and parent will be saved without error messages, but the relationship related database data is missing. So, as a general guideline: always update both sides of the relationship, this will avoid a lot of problems ;-).

I have the same problem in production with Jboss 3.2.3. Did you ever manage to find a solution ? Personally, I suspect a memory exhaustion problem.
