21. OC4J Clustering Services A cluster can be thought of a collection of servers operating together that provide: –Load balancing –High availability –Fault tolerance OC4J provides these clustering services –Load balancing –High availability –Fault tolerance

22. OC4J Load Balancing Load balancer routes incoming client requests over multiple OC4J servers –Load balancer treats OC4J servers as a pool to handle incoming requests –Optimizes requests by servicing clients with same server

23. OC4J High Availability Failed server detection –Load balancer detects failed servers –Load balancer routes requests around failed servers Dynamic server binding –Servers register with load balancer when they start –Load balancer adds server to pool upon registration

24. OC4J Application Failover Ensures that client sees no loss of service when a server failure occurs –Client state made available to fail-over servers Cluster island –Servers grouped together inside of cluster Replicated application state –HttpSession objects; client specific state

25. Web Application Clustering Cluster Island 2 Cluster Island 1 Load Balancer One application server cluster Five application server nodes Two cluster islands Load balancer Application Server Cluster

26. Web Application Clustering Cluster Island 1 Cluster Island 2 Load Balancer Each server registers with the load balancer at startup Application Server Cluster

27. Web Application Clustering Cluster Island 1 Cluster Island 2 Load Balancer Client Client makes requests for a web application Load balancer intercepts request Application Server Cluster A B C

28. Web Application Clustering Cluster Island 1 Cluster Island 2 Load Balancer Client LB routes request to a server for processing Server A creates session for client Application Server Cluster Server A generates and sends response A B C

29. Web Application Clustering Cluster Island 1 Cluster Island 2 Load Balancer Client HttpSession Server A sends HttpSession object to other servers in cluster island Application Server Cluster State not sent to servers in other cluster islands A B C

30. Web Application Clustering Cluster Island 1 Cluster Island 2 Load Balancer Client HttpSession Future requests from same client directed to same server node for efficiency Application Server Cluster HttpSession object continues to be updated on all nodes within cluster island A B C

31. Web Application Clustering Cluster Island 1 Cluster Island 2 Load Balancer Client HttpSession X Server A experiences a major failure and stops functioning Application Server Cluster A B C

32. Web Application Clustering Cluster Island 1 Cluster Island 2 Load Balancer Client HttpSession X Client makes next request LB detects failure of server A LB routes request to another server in same island Server B generates response using replicated HttpSession object and sends to client Application Server Cluster A B C

33. Web Application Clustering Cluster Island 1 Cluster Island 2 Load Balancer Client HttpSession X Client sees no interruption of service due to the failure of server A Application Server Cluster Server B sends updated HttpSession object to servers in cluster A B C
