@Nancy, Could you give more details bout this implementation? Is that working together with tomcat clustering?
From: Nancy Snoke [mailto:[email protected]] Sent: Tuesday, April 08, 2014 12:16 AM To: [email protected] Subject: RE: [cas-user] Using cluster Env on Amazon I personally have CAS working with a replicated Ehcach using JGroups communication via TCP unicast. The cacheManagerPeerProviderFactory is set up like: <cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.jgroups.JGroupsCacheManagerPeerProviderFactory" properties="connect=TCP(bind_port=41001): TCPPING(initial_hosts=hostname2[41001],hostname1[41001];port_range=10;timeout=3000;num_initial_members=2): MERGE2: VERIFY_SUSPECT(timeout=1500): pbcast.NAKACK2(use_mcast_xmit=false;discard_delivered_msgs=true): UNICAST2: pbcast.STABLE(stability_delay=1000;desired_avg_gossip=50000): FRAG2: pbcast.GMS(join_timeout=5000;print_local_addr=true;view_bundling=true;max_join_attempts=0)" propertySeparator="::" /> OF course you can just read the JGroups documentation to decide what setting are right for your setup. Ehcahce with JGroups communication is very configurable although the documentation is a little difficult. I found the following links useful: https://wiki.jasig.org/display/CASUM/EhcacheTicketRegistry http://ehcache.org/documentation/replication/jgroups-replicated-caching http://www.jgroups.org/manual/html/user-advanced.html From: Cedric Hurst [mailto:[email protected]] Sent: Monday, April 07, 2014 10:47 AM To: [email protected]<mailto:[email protected]> Subject: Re: [cas-user] Using cluster Env on Amazon You probably want to do static membership. The CAS article simply describes Tomcat clustering, but here's some more info on doing it without multicast: http://www.rotanhanrahan.com/2012/01/06/tomcat-cluster-apache-lbr-and-replication http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2009794 -- Build Smarter Software.

As I understand I must have multicast on the network. Amazon doesnt support multicast. any proven way how to backdoor this? found some links on the web but not sure about their legitimate thanks, ray. -- You are currently subscribed to [email protected]<mailto:[email protected]> as: [email protected]<mailto:[email protected]> To unsubscribe, change settings or access archives, see http://www.ja-sig.org/wiki/display/JSG/cas-user -- You are currently subscribed to [email protected]<mailto:[email protected]> as: [email protected]<mailto:[email protected]> To unsubscribe, change settings or access archives, see http://www.ja-sig.org/wiki/display/JSG/cas-user -- You are currently subscribed to [email protected]<mailto:[email protected]> as: [email protected]<mailto:[email protected]> To unsubscribe, change settings or access archives, see http://www.ja-sig.org/wiki/display/JSG/cas-user This e-mail and the information it contains may be privileged and/or confidential.
