- <!-- 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

- 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

- 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
