Re: Clustering in tomcat
Thanks filip... sessions are replicating now but still there are some issues. can u please tell me sometimes it doesn't replicate session and i get session not found error in logs and screen crashes. 2008-11-10 13:45:50,703 INFO [com.vopium.interceptors.SecurityInterceptor - preHandle] - request.getRemoteAddr() 192.168.0.82 request.getRemoteHost() 192.168.0.82 /vopium/getproductlist.htm 2008-11-10 13:45:50,711 INFO [com.vopium.interceptors.SecurityInterceptor - preHandle] - Session Not Found So Redirecting to Login and requested uri is /vopium/getproductlist.htm (and after this screen crashes) also i am unable to understand following point that i got in clustering basics information The IP broadcasted is java.net.InetAddress.getLocalHost().getHostAddress() (make sure you don't broadcast 127.0.0.1, this is a common error) also there is another issue that when one tomcat gets down then apache takes some time to move to other server and meanwhile i get screen saying service temporarily unavailable after some time (15-25 seconds) when i refresh ...screen starts from same point with no session failure and apache sends hit to 2nd tomcat. Actually i am not the developer of this application i am just a configuration engineer... therefor it takes me time to understand that issue is either related to configuration or application end. waiting for helpful reply Filip Hanik - Dev Lists wrote: http://tomcat.apache.org/tomcat-6.0-doc/ look for Cluster Basics Filip kashif_tomcat wrote: Thanks Filip... i have got out of that problem... after adding clustering port in iptable. now i am getting another exception and following is detail. when i add distributable/ tag in web.xml of my applicatoin and start tomcat. then after login my application crashs and i get following exception in logs. 2008-10-30 21:19:43,812 INFO [com.vopium.controller.LoginController - handleControllerRequest] - Exception during LoginProcess setAttribute: Non-serializable attribute com.framework.exceptions.BaseRunTimeException at org.apache.catalina.session.StandardSession.setAttribute(StandardSession.java:1295) at org.apache.catalina.ha.session.DeltaSession.setAttribute(DeltaSession.java:567) at org.apache.catalina.ha.session.DeltaSession.setAttribute(DeltaSession.java:551) at org.apache.catalina.session.StandardSessionFacade.setAttribute(StandardSessionFacade.java:130) at com.vopium.controller.LoginController.handleControllerRequest(Unknown Source) at com.framework.controllers.BaseController.handleRequestInternal(Unknown Source) at org.springframework.web.servlet.mvc.AbstractController.handleRequest(AbstractController.java:153) at org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter.handle(SimpleControllerHandlerAdapter.java:48) at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:875) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:809) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:571) at org.springframework.web.servlet.FrameworkServlet.doPost(FrameworkServlet.java:511) at javax.servlet.http.HttpServlet.service(HttpServlet.java:637) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at com.vopium.portal.utilities.URLFilter.doFilter(Unknown Source) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.ha.session.JvmRouteBinderValve.invoke(JvmRouteBinderValve.java:209) at org.apache.catalina.ha.tcp.ReplicationValve.invoke(ReplicationValve.java:347) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286) at org.apache.jk.server.JkCoyoteHandler.invoke(JkCoyoteHandler.java:190) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:283) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:767) at
