+WebApp Load Balancing Demo
+===========================
+
+Demonstrates balancing load acoss SCA services by deploying an SCA composite
+to two tomcat servers in a cluster. The tomcat servers sit behind an Apache
+server which directs load to one or other tomcat server based on a set of rules.
+
+The mvn pom distributed with this sample will download, install and configure
+two Tomcat servers automatically to act as workers. You need to install the
+Apache web server and configure it manually.
+
+1 - Install and configure the Tomcat workers
+
+mvn
+
+This results in two tomcat servers at
+
+target/tomcat-8085
+target/tomcat-8086
+
+2 - Install and configure the Apache server to balance load
+
+In this case we've chosen to use the native JK connector. There are several
+resources that tell you how to configure Apache for load balancing Tomcat with
+the JK connector. For example,
+
+http://tomcat.apache.org/connectors-doc/webserver_howto/apache.html
+http://www.crazysquirrel.com/computing/debian/servers/tomcat55.jspx
+
+Here is a high level summary
+
+Download the latest version of Apache 2.2 (this demo was built with Apache 2.2.6)
+ http://httpd.apache.org/
+ Install in a local director called, say, apache
+
+Download the mod_jk module (in binary form if you can)
+ http://tomcat.apache.org/download-connectors.cgi
+ Install it in apache/modules
+
+Configure the mod_jk module
+ Copy src/test/resources/apache-80/conf/workers.properties to apache/conf
+ Append the contents of src/test/resources/apache-80/conf/httpd.conf to apache/conf/httpf.conf
+
+3 - Start the apache and tomcat servers
+
+In three command prompts
+
+cd target/tomcat-8085
+bin/catalina run
+
+cd target/tomcat-8086
+bin/catalina run
+
+cd apache
+bin/httpd
+
+4 - Run the client
+
+run the LanchClient program - TBD - need a script
+
+5 - Result
+
+The client will make 10 calls to the SCA service described in the helloworldws.composite that
+is part of the webapp deployed to the tomcat servers. You will see the result of this
+service call reported at the client in the form
+
+Called getGreetings
+Hello World 6
+
+If you look at the Tomcat consoles you will see that each server deals with half the requests
+as the load is balanced equally between the two of them.

+ <!-- Defines a cluster for this node,
+ By defining this element, means that every manager will be changed.
+ So when running a cluster, only make sure that you have webapps in there
+ that need to be clustered and remove the other ones.
+ A cluster has the following parameters:
+
+ className = the fully qualified name of the cluster class
+
+ clusterName = a descriptive name for your cluster, can be anything
+
+ mcastAddr = the multicast address, has to be the same for all the nodes
+
+ mcastPort = the multicast port, has to be the same for all the nodes
+
+ mcastBindAddress = bind the multicast socket to a specific address
+
+ mcastTTL = the multicast TTL if you want to limit your broadcast
+
+ mcastSoTimeout = the multicast readtimeout
+
+ mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat
+
+ mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received
+
+ tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes
+
+ tcpListenAddress = the listen address (bind address) for TCP cluster request on this host,
+ in case of multiple ethernet cards.
+ auto means that address becomes
+ InetAddress.getLocalHost().getHostAddress()
+
+ tcpListenPort = the tcp listen port
+
+ tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS
+ has a wakup bug in java.nio. Set to 0 for no timeout
+
+ printToScreen = true means that managers will also print to std.out
+
+ expireSessionsOnShutdown = true means that
+
+ useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called.
+ false means to replicate the session after each request.
+ false means that replication would work for the following piece of code: (only for SimpleTcpReplicationManager)
+ <%
+ HashMap map = (HashMap)session.getAttribute("map");
+ map.put("key","value");
+ %>
+ replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'.
+ * Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
+ * Synchronous means that the thread that executes the request, is also the
+ thread the replicates the data to the other nodes, and will not return until all
+ nodes have received the information.
+ * Asynchronous means that there is a specific 'sender' thread for each cluster node,
+ so the request thread will queue the replication request into a "smart" queue,
+ and then return to the client.
+ The "smart" queue is a queue where when a session is added to the queue, and the same session
+ already exists in the queue from a previous request, that session will be replaced
+ in the queue instead of replicating two requests. This almost never happens, unless there is a
+ large network delay.
+ -->
+ <!--
+ When configuring for clustering, you also add in a valve to catch all the requests
+ coming in, at the end of the request, the session may or may not be replicated.
+ A session is replicated if and only if all the conditions are met:
+ 1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND
+ 2. a session exists (has been created)
+ 3. the request is not trapped by the "filter" attribute
+
+ The filter attribute is to filter out requests that could not modify the session,
+ hence we don't replicate the session after the end of this request.
+ The filter is negative, ie, anything you put in the filter, you mean to filter out,
+ ie, no replication will be done on requests that match one of the filters.
+ The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
+
+ filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI
+ ending with .gif and .js are intercepted.
+
+ The deployer element can be used to deploy apps cluster wide.
+ Currently the deployment only deploys/undeploys to working members in the cluster
+ so no WARs are copied upons startup of a broken node.
+ The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
+ When a new war file is added the war gets deployed to the local instance,
+ and then deployed to the other instances in the cluster.
+ When a war file is deleted from the watchDir the war is undeployed locally
+ and cluster wide

+ So when running a cluster, only make sure that you have webapps in there

+ A cluster has the following parameters:
+
+ className = the fully qualified name of the cluster class
+
+ clusterName = a descriptive name for your cluster, can be anything
+
+ mcastAddr = the multicast address, has to be the same for all the nodes
+
+ mcastPort = the multicast port, has to be the same for all the nodes
+
+ mcastBindAddress = bind the multicast socket to a specific address
+
+ mcastTTL = the multicast TTL if you want to limit your broadcast
+
+ mcastSoTimeout = the multicast readtimeout
+
+ mcastFrequency = the number of milliseconds in between sending a "I'm alive" heartbeat
+
+ mcastDropTime = the number a milliseconds before a node is considered "dead" if no heartbeat is received
+
+ tcpThreadCount = the number of threads to handle incoming replication requests, optimal would be the same amount of threads as nodes
+
+ tcpListenAddress = the listen address (bind address) for TCP cluster request on this host,
+ in case of multiple ethernet cards.
+ auto means that address becomes
+ InetAddress.getLocalHost().getHostAddress()
+
+ tcpListenPort = the tcp listen port
+
+ tcpSelectorTimeout = the timeout (ms) for the Selector.select() method in case the OS
+ has a wakup bug in java.nio. Set to 0 for no timeout
+
+ printToScreen = true means that managers will also print to std.out
+
+ expireSessionsOnShutdown = true means that
+
+ useDirtyFlag = true means that we only replicate a session after setAttribute,removeAttribute has been called.
+ false means to replicate the session after each request.
+ false means that replication would work for the following piece of code: (only for SimpleTcpReplicationManager)
+ <%
+ HashMap map = (HashMap)session.getAttribute("map");
+ map.put("key","value");
+ %>
+ replicationMode = can be either 'pooled', 'synchronous' or 'asynchronous'.
+ * Pooled means that the replication happens using several sockets in a synchronous way. Ie, the data gets replicated, then the request return. This is the same as the 'synchronous' setting except it uses a pool of sockets, hence it is multithreaded. This is the fastest and safest configuration. To use this, also increase the nr of tcp threads that you have dealing with replication.
+ * Synchronous means that the thread that executes the request, is also the
+ thread the replicates the data to the other nodes, and will not return until all
+ nodes have received the information.
+ * Asynchronous means that there is a specific 'sender' thread for each cluster node,
+ so the request thread will queue the replication request into a "smart" queue,
+ and then return to the client.
+ The "smart" queue is a queue where when a session is added to the queue, and the same session
+ already exists in the queue from a previous request, that session will be replaced
+ in the queue instead of replicating two requests. This almost never happens, unless there is a
+ large network delay.
+ -->
+ <!--
+ When configuring for clustering, you also add in a valve to catch all the requests
+ coming in, at the end of the request, the session may or may not be replicated.
+ A session is replicated if and only if all the conditions are met:
+ 1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND
+ 2. a session exists (has been created)
+ 3. the request is not trapped by the "filter" attribute
+
+ The filter attribute is to filter out requests that could not modify the session,
+ hence we don't replicate the session after the end of this request.
+ The filter is negative, ie, anything you put in the filter, you mean to filter out,
+ ie, no replication will be done on requests that match one of the filters.
+ The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
+
+ filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI
+ ending with .gif and .js are intercepted.
+
+ The deployer element can be used to deploy apps cluster wide.
+ Currently the deployment only deploys/undeploys to working members in the cluster
+ so no WARs are copied upons startup of a broken node.
+ The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
+ When a new war file is added the war gets deployed to the local instance,
+ and then deployed to the other instances in the cluster.
+ When a war file is deleted from the watchDir the war is undeployed locally
+ and cluster wide

+ When configuring for clustering, you also add in a valve to catch all the requests
+ coming in, at the end of the request, the session may or may not be replicated.
+ A session is replicated if and only if all the conditions are met:
+ 1. useDirtyFlag is true or setAttribute or removeAttribute has been called AND
+ 2. a session exists (has been created)
+ 3. the request is not trapped by the "filter" attribute
+
+ The filter attribute is to filter out requests that could not modify the session,
+ hence we don't replicate the session after the end of this request.
+ The filter is negative, ie, anything you put in the filter, you mean to filter out,
+ ie, no replication will be done on requests that match one of the filters.
+ The filter attribute is delimited by ;, so you can't escape out ; even if you wanted to.
+
+ filter=".*\.gif;.*\.js;" means that we will not replicate the session after requests with the URI
+ ending with .gif and .js are intercepted.
+
+ The deployer element can be used to deploy apps cluster wide.
+ Currently the deployment only deploys/undeploys to working members in the cluster
+ so no WARs are copied upons startup of a broken node.
+ The deployer watches a directory (watchDir) for WAR files when watchEnabled="true"
+ When a new war file is added the war gets deployed to the local instance,
+ and then deployed to the other instances in the cluster.
+ When a war file is deleted from the watchDir the war is undeployed locally
+ and cluster wide
