Hi David, I'll try to answer yout questions:
1) How does CAS store the database of tickets that were generated for > clients? Is it stored in memory or perhaps a flat file on the host > computer? The ticket registry is stored in memory on each cas server. 2) Within a cluster of CAS servers, how often does the ticket data get > replicated? If one peer server goes offline then online, does the session > data (as well as the ticket data) get replicated immediately or is there an > interval at which this happens? I am assuming there must be some > handshaking process between the new server and existing servers thus > allowing the new server to sync up with the cluster. The ticket replication is managed through two different mechanisms: client-side cookies are replicated using the cluster feature of the application server (tomcat), while the cas ticket registry is replicated among the cluster nodes using some other "pluggable" method. The document you read explains how to set up this through the jboss-cache libraries. In both cases, the syncronization method can be configured, but for cas cluster to work properly it should be set in syncronous mode, which means that data is replicated between the nodes each time it's modified. 3) Finally is there a way to manually perform a memory dump of the CAS > server? In my intrusion framework, servers will go offline and online at > specific time intervals so ideally it would be beneficial to dump the > current data on the CAS server before shutting it down. I don't think so. Thank you all in advance! De nada.. -- Claudio Tassini
