[JBoss-dev] [JBoss-user] capacity planning to use jboss
Today i got a question from my manager (i work in a bank, there will be a web layer at the bank office and a central ejb layer) : Emerson, how many boxes in the ejblayer do we need to support 800 offices and more than 4000 simultaneous clients (from the offices). Imagine that you have available any number of xeon dual 2mhz with 2giga RAM connected through a gigabit lan, how many boxes of this kind do we need? I confess that i exitated a little. This is a though question, indeed. I think that CMP and mainly clustering will not have the same gain when you have too many nodes in the cluster, given the communication needed among the nodes to keep the data replicated. Does any one have any parameter for a capacity plan for a scenario like this? jboss group, any clue ?? What could be the limit beetwen number of nodes and replication overhead? Thanks in advance for any answer : ) -- | Emerson Cargnin | | Analista de Sistemas Sr. | | Tel : (051) 3358-4959| | SICREDI Serviços | | Porto Alegre - Brasil| |xx| --- This sf.net email is sponsored by: viaVerio will pay you up to $1,000 for every account that you consolidate with us. http://ad.doubleclick.net/clk;4749864;7604308;v? http://www.viaverio.com/consolidator/osdn.cfm ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user --- This sf.net email is sponsored by: viaVerio will pay you up to $1,000 for every account that you consolidate with us. http://ad.doubleclick.net/clk;4749864;7604308;v? http://www.viaverio.com/consolidator/osdn.cfm ___ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development

- You'll probably want to buy some Hardware based HTTP load-balancer for your web traffic. Make sure it supports sticky sessions. You can try Apache + modjk + AJP13 if you want a cheap software solution. Jetty and Tomcat can be hooked in. - Do you require HTTP Session replication and failover? If its ok for a user to relogin after a failover, I suggest not using JBoss clustering features at all, (Except for net boot and maybe farming). - On the performance tests I ran(ECPERF), replication had a 10% hit on performance for 2 boxes running in a cluster. You'll probably have more than 2 boxes(but not much more). - I suggest marrying the WEB and EJB layer into one JVM/process. You'll get better performance. - Next what you have to do is guess peak traffic. Multiply that number by 2 just to be safe. - Next you'll need to write a stress test program - Next you'll need to hire JBossGroup to help you out with all of this. :) - Next you'll need to purchase a high quality support contract from JBossGroup to iron out any problems you may have :) At Mercantec we had 2 dual 900mhz CPU running Linux and JBoss, 1 dual 900Mgz PIII running Oracle. We could support traffic from 10K merchants. But that's our application. How many users your app can support on a given piece of hardware is totally dependent on the type of application you're running. DON'T USE CLUSTERING UNLESS YOU HAVE TO!

RE: [JBoss-dev] [JBoss-user] capacity planning to use jboss
Bill, This is interesting about not using clustering.. Are you guys using CMP at all? If so, how do you suggest synching the entity beans without using clustering? On a site without CMP, you can usually get away from clustering, but wondering if you have used the equiv of Javelin to do distributed caching, deployed the CMPs a specific way, or just depend on pessimistic locking and the DB vendor.

[JBoss-dev] Building JBoss / Tomcat bundle for Tomcat 4.1.x
Hey, all. I'm trying to build a JBoss 3.0.x / Tomcat 4.1.x bundle (for internal use at my company) as an interim until JBoss 3.0.4 is officially released. When I build a bundle with Tomcat 4.0.x, following the instructions in the readme file in the catalina directory works fine. However, when I try the same instructions for Tomcat 4.1.x, I get build breaks related to XML stuff (see below). I'm pretty sure it's possible to bundle 4.1.x because there is a JBoss-3.0.3_Tomcat-4.1.12 available for download on SourceForge. Has something changed?

Re: [JBoss-dev] [JBoss-user] capacity planning to use jboss
Some additional comments: 1) If a hardware load balancer is out of the budget (Cisco local director series start at about $4000 - not too expensive), then I would recommend looking at Linux Virtual Server (http://www.linuxvirtualserver.org/). It is basically a customized Linux kernel to do the same stuff as the hardware solution. 2) We do not want to use clustered http sessions, because frankly our sessions are too damn bloated (yeah - we need to fix that, but alas there is only so much time in a day). I was thinking about a way to cluster just enough session info to preserve login context, but to ignore the rest of the junk that is not needed (most of the our http session info is just database cache that can be recreated as needed). Basically, the clustered servers would only share session-id/login-id pairs. I haven't spent any time actually working on this, but I would love to hear comments. Might this be useful to others? -Larry - You'll probably want to buy some Hardware based HTTP load-balancer for your web traffic. Make sure it supports sticky sessions.

Easy. How to sync Entities? Use Commit 'B' and row-locking if using CMP, or select...for update for BMPs in ejbLoad. row-locking uses Select ...FOR UPDATE on ejbLoad. In CVS HEAD, Sacha and I have implemented a distributed cache via cache invalidation, but we still rely on DB for the distributed lock. A real Clustered distributed lock is in the works.

RE: [JBoss-dev] [JBoss-user] capacity planning to use jboss
JBoss clustering does load-balanching for ejb types. EB's and SFSB's are sticky for performance reasons. But all home invocations and SLSB invocations are round-robin by default. IN JBoss 3.0.x CMP does not have a distributed cache. So you would need to use commit 'B'. Hire us, we'll help you out.

It is basically a customized Linux kernel to do the same stuff as the hardware solution. 2) We do not want to use clustered http sessions, because frankly our sessions are too damn bloated (yeah - we need to fix that, but alas there is only so much time in a day). I was thinking about a way to cluster just enough session info to preserve login context, but to ignore the rest of the junk that is not needed (most of the our http session info is just database cache that can be recreated as needed). Basically, the clustered servers would only share session-id/login-id pairs. I haven't spent any time actually working on this, but I would love to hear comments.

[JBoss-dev] JMS Delivery Threads/Arch question
Howdy all Ive been messing with the JMS Selectors to implement the ability to do a delivery time on a message for MDBs. Basically added in a CURRENT_TIMESTAMP into the selector which gets translated into the current time on parsing. (Its not in spec but i need some sort of delay mechanism). Problem is i cant seem to find a thread which looks over the messages on the queue currently and compares them to current subscribers selectors again. This appears to be only checking on initial receipt of the message on the queue. Is this actually the case or am I just missing something?
