I had looked at openmosix for this purpose, I thinkt he rpm beta is a good choice for experimentation. http://openmosix.sourceforge.net/ http://sourceforge.net/project/showfiles.php?group_id=46729&package_id=177868

With open mosix, I'm not sure of all of the issues related to database replication. The primary thrust of openmosix is that all procesess are distributed transparently over the cluster. > I would like to know your advices regarding the best way to replicate the > databases: mysql replication features?

That's the beauty of openmosix: <snip> What is openMosix? openMosix is a Linux kernel extension for single-system image clustering. This kernel extension turns a network of ordinary computers into a supercomputer for Linux applications. Once you have installed openMosix, the nodes in the cluster start talking to one another and the cluster adapts itself to the workload. Processes originating from any one node, if that node is too busy compared to others, can migrate to any other node. openMosix continuously attempts to optimize the resource allocation. We achieve this with a kernel patch for Linux, creating a reliable, fast and cost-efficient SSI clustering platform that is linearly scalable and adaptive. With openMosix' Auto Discovery, a new node can be added while the cluster is running and the cluster will automatically begin to use the new resources. There is no need to program applications specifically for openMosix. Since all openMosix extensions are inside the kernel, every Linux application automatically and transparently benefits from the distributed computing concept of openMosix. The cluster behaves much as does a Symmetric Multi-Processor, but this solution scales to well over a thousand nodes which can themselves be SMPs. The openMosix Community is very active, contributing add-on applications and sharing helpful information with all users. The openMosix Add-Ons and Community page lists these shared applications. And, it is all GPL'd. <snip> hth, James > > > TIA > > > _______________ > David LIMA > Professional Services > www.scc.com > > > > > > ______________________________________________________________________ > Ce message contient des informations dont le contenu est susceptible d'etre > confidentiel. > Il est destine au(x) destinataire(s) indique(s) exclusivement. > > A moins que vous ne fassiez partie de la liste des destinataires, ou que vous > soyez habilite a recevoir le mail a leur place, il vous est interdit de le > copier, de l'utiliser ou de devoiler son contenu a un tiers. > > Si vous avez recu cet email par erreur, merci de prendre contact avec > l'emetteur. > > Les opinions exprimees dans cet e-mail sont celles de l'emetteur et ne > refletent pas necessairement celles de l'entreprise. > > Ce e-mail peut contenir des pieces jointes dont certaines pourraient contenir > des virus qui pourraient endommager votre systeme informatique. > > La compagnie a pris toutes dispositions afin de minimiser ce risque et > decline toute responsabilite pour toute perte ou dommage resultant > directement ou indirectement de l'utilisation de cet email ou de son contenu. > > Il vous appartient d'effectuer vos propres controles anti-virus avant > d'ouvrir la ou les pieces jointes. > ______________________________________________________________________ > > ------------------------------------------------------------------------- > Using Tomcat but need to do more?
