1、最新资料推荐xml配置文件-计算机安全 xml配置文件 !- - !- - !- You should set jvmRoute to support load-balancing via AJP ie : - !- The request dumper valve dumps useful debugging information about the request headers and cookies that were received, and the response headers and cookies that were sent, for all requests rec

2、eived by this instance of Tomcat. If you care only about requests to a particular virtual host, or a particular application, nest this element inside the corresponding or entry instead. For a similar mechanism that is portable to all Servlet 2.4 containers, check out the RequestDumperFilter Filter i

3、n the example application (the source for this filter may be found in $CATALINA_HOME/webapps/examples/WEB-INF/classes/filters). Request dumping is disabled by default. Uncomment the following element to enable it. - !- - !- - !- - !- - !- - maxActive 100 maxIdle 30 maxWait 10000 removeAbandoned true

4、 removeAbandonedTimeout 60 logAbandoned false factory mons.dbcp.BasicdataSourceFactory username Iorishinier password mypasswd driverClassName com.microsoft.jdbc.sqlserver.SQLServerDriver url jdbc:microsoft:sqlserver:/localhost:1433;DatabaseName=cdstore !- Defines a cluster for this node, By defining

5、 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 name = a descriptiv

6、e 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 mcastBindAddr = bind the multicast socket to a specific address mcastTTL = the multicast TTL if you want to limit your

7、 broadcast mcastSoTimeout = the multicast readtimeout mcastFrequency = the number of milliseconds in between sending a Im 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 r

8、eplication 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

9、 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 onl

10、y 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) replicationMode = can be either pooled, synchronous or as

11、ynchronous. * 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 configura

12、tion. 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. * Asynchrono

13、us 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
