+ <!-- 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

+
+ 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.
