<section class="normal markdown-section"> + + <h1 id="spring-integration">Spring Integration</h1> +<p>Apache ActiveMQ Artemis provides a simple bootstrap class, +<code>org.apache.activemq.integration.spring.SpringJmsBootstrap</code>, for +integration with Spring. To use it, you configure Apache ActiveMQ Artemis as you always +would, through its various configuration files like +<code>broker.xml</code>.</p> +<p>Here we've specified a <code>javax.jms.ConnectionFactory</code> we want bound to a +<code>ConnectionFactory</code> entry as well as a queue destination bound to a +<code>/queue/exampleQueue</code> entry. Using the <code>SpringJmsBootStrap</code> bean will +automatically populate the Spring context with references to those beans +so that you can use them. Below is an example Spring JMS bean file +taking advantage of this feature:</p> +<pre><code><beans xmlns="http://www.springframework.org/schema/beans" + xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" + xsi:schemaLocation="http://www.springframework.org/schema/beans + http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> + + <bean id="EmbeddedJms" class="org.apache.activemq.integration.spring.SpringJmsBootstrap" init-method="start"/> + + <bean id="listener" class="org.apache.activemq.tests.integration.spring.ExampleListener"/> + + <bean id="listenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> + <property name="connectionFactory" ref="ConnectionFactory"/> + <property name="destination" ref="/queue/exampleQueue"/> + <property name="messageListener" ref="listener"/> + </bean> +</beans> +</code></pre><p>As you can see, the <code>listenerContainer</code> bean references the components +defined in the <code>activemq-jms.xml</code> file. The <code>SpringJmsBootstrap</code> class +extends the EmbeddedJMS class talked about in <a href="embedding-activemq.html">JMS API</a> and the same defaults +and configuration options apply. Also notice that an <code>init-method</code> must +be declared with a start value so that the bean's lifecycle is executed. +See the javadocs for more details on other properties of the bean class.</p> + + + </section> + + </div> + <div class="search-results"> + <div class="has-results"> + + <h1 class="search-results-title"><span class='search-results-count'></span> results matching "<span class='search-query'></span>"</h1> + <ul class="search-results-list"></ul> + + </div> + <div class="no-results"> + + <h1 class="search-results-title">No results matching "<span class='search-query'></span>"</h1> + + </div> + </div> +</div> + + </div> + </div> + + </div> + + + + <a href="karaf.html" class="navigation navigation-prev " aria-label="Previous page: Apache Karaf"> + <i class="fa fa-angle-left"></i> + </a> + + + <a href="cdi-integration.html" class="navigation navigation-next " aria-label="Next page: CDI Integration"> + <i class="fa fa-angle-right"></i> + </a> + + + + </div> + + <script> + var gitbook = gitbook || []; + gitbook.push(function() { + gitbook.page.hasChanged({"page":{"title":"Spring Integration","level":"1.56","depth":1,"next":{"title":"CDI Integration","level":"1.57","depth":1,"path":"cdi-integration.md","ref":"cdi-integration.md","articles":[]},"previous":{"title":"Apache Karaf","level":"1.55","depth":1,"path":"karaf.md","ref":"karaf.md","articles":[]},"dir":"ltr"},"config":{"plugins":[],"styles":{"website":"styles/website.css","pdf":"styles/pdf.css","epub":"styles/epub.css","mobi":"styles/mobi.css","ebook":"styles/ebook.css","print":"styles/print.css"},"pluginsConfig":{"highlight":{},"search":{},"lunr":{"maxIndexSize":1000000},"sharing":{"facebook":true,"twitter":true,"google":false,"weibo":false,"instapaper":false,"vk":false,"all":["facebook","google","twitter","weibo","instapaper"]},"fontsettings":{"theme":"white","family":"sans","size":2},"theme-default":{"styles":{"website":"styles/website.css","pdf":"styles/pdf.css","epub":"styles/epub.css","mobi":"styles/mobi.css","ebook":"styles/ebook.css"," print":"styles/print.css"},"showLevel":false}},"github":"apache/activemq-artemis","theme":"default","githubHost":"https://github.com/","pdf":{"pageNumbers":true,"fontSize":12,"fontFamily":"Arial","paperSize":"a4","chapterMark":"pagebreak","pageBreaksBefore":"/","margin":{"right":62,"left":62,"top":56,"bottom":56}},"structure":{"langs":"LANGS.md","readme":"README.md","glossary":"GLOSSARY.md","summary":"SUMMARY.md"},"variables":{},"title":"ActiveMQ Artemis Documentation","links":{"home":"http://activemq.apache.org/artemis","issues":"https://issues.apache.org/jira/browse/ARTEMIS","contribute":"http://activemq.apache.org/contributing.html"},"gitbook":"3.x.x","description":"ActiveMQ Artemis User Guide and Reference Documentation"},"file":{"path":"spring-integration.md","mtime":"2017-09-05T13:43:48.000Z","type":"markdown"},"gitbook":{"version":"3.1.1","time":"2017-09-14T19:42:32.953Z"},"basePath":".","book":{"language":""}}); + }); + </script> +</div> + + + <script src="gitbook/gitbook.js"></script> + <script src="gitbook/theme.js"></script> + + + <script src="gitbook/gitbook-plugin-search/search-engine.js"></script> + + + + <script src="gitbook/gitbook-plugin-search/search.js"></script> + + + + <script src="gitbook/gitbook-plugin-lunr/lunr.min.js"></script> + + + + <script src="gitbook/gitbook-plugin-lunr/search-lunr.js"></script> + + + + <script src="gitbook/gitbook-plugin-sharing/buttons.js"></script> + + + + <script src="gitbook/gitbook-plugin-fontsettings/fontsettings.js"></script> + + + + </body> +</html> +

class="normal markdown-section"> + + <h1 id="thread-management">Thread management</h1> +<p>This chapter describes how Apache ActiveMQ Artemis uses and pools threads and how you +can manage them.</p> +<p>First we'll discuss how threads are managed and used on the server side, +then we'll look at the client side.</p> +<h2 id="server-side-thread-management">Server-Side Thread Management</h2> +<p>Each Apache ActiveMQ Artemis Server maintains a single thread pool for general use, and +a scheduled thread pool for scheduled use. A Java scheduled thread pool +cannot be configured to use a standard thread pool, otherwise we could +use a single thread pool for both scheduled and non scheduled activity.</p> +<p>Apache ActiveMQ Artemis will, by default, cap its thread pool +at three times the number of cores (or hyper-threads) as reported by <code>Runtime.getRuntime().availableProcessors()</code> for processing +incoming packets. To override this value, you can set the number of +threads by specifying the parameter <code>nioRemotingThreads</code> in the +transport configuration. See the <a href="configuring-transports.html">configuring transports</a> +for more information on this.</p> +<p>There are also a small number of other places where threads are used +directly, we'll discuss each in turn.</p> +<h3 id="server-scheduled-thread-pool">Server Scheduled Thread Pool</h3> +<p>The server scheduled thread pool is used for most activities on the +server side that require running periodically or with delays. It maps +internally to a <code>java.util.concurrent.ScheduledThreadPoolExecutor</code> +instance.</p> +<p>The maximum number of thread used by this pool is configure in +<code>broker.xml</code> with the <code>scheduled-thread-pool-max-size</code> +parameter. The default value is <code>5</code> threads. A small number of threads +is usually sufficient for this pool.</p> +<h3 id="general-purpose-server-thread-pool">General Purpose Server Thread Pool</h3> +<p>This general purpose thread pool is used for most asynchronous actions +on the server side. It maps internally to a +<code>java.util.concurrent.ThreadPoolExecutor</code> instance.</p> +<p>The maximum number of thread used by this pool is configure in +<code>broker.xml</code> with the <code>thread-pool-max-size</code> parameter.</p> +<p>If a value of <code>-1</code> is used this signifies that the thread pool has no +upper bound and new threads will be created on demand if there are not +enough threads available to satisfy a request. If activity later +subsides then threads are timed-out and closed.</p> +<p>If a value of <code>n</code> where <code>n</code>is a positive integer greater than zero is +used this signifies that the thread pool is bounded. If more requests +come in and there are no free threads in the pool and the pool is full +then requests will block until a thread becomes available. It is +recommended that a bounded thread pool is used with caution since it can +lead to dead-lock situations if the upper bound is chosen to be too low.</p> +<p>The default value for <code>thread-pool-max-size</code> is <code>30</code>.</p> +<p>See the <a href="http://docs.oracle.com/javase/6/docs/api/java/util/concurrent/ThreadPoolExecutor.htm"; target="_blank">J2SE +javadoc</a> +for more information on unbounded (cached), and bounded (fixed) thread +pools.</p> +<h3 id="expiry-reaper-thread">Expiry Reaper Thread</h3> +<p>A single thread is also used on the server side to scan for expired +messages in queues. We cannot use either of the thread pools for this +since this thread needs to run at its own configurable priority.</p> +<p>For more information on configuring the reaper, please see <a href="message-expiry.html">message expiry</a>.</p> +<h3 id="asynchronous-io">Asynchronous IO</h3> +<p>Asynchronous IO has a thread pool for receiving and dispatching events +out of the native layer. You will find it on a thread dump with the +prefix ActiveMQ-AIO-poller-pool. Apache ActiveMQ Artemis uses one thread per opened +file on the journal (there is usually one).</p> +<p>There is also a single thread used to invoke writes on libaio. We do +that to avoid context switching on libaio that would cause performance +issues. You will find this thread on a thread dump with the prefix +ActiveMQ-AIO-writer-pool.</p> +<h2 id="client-side-thread-management">Client-Side Thread Management</h2> +<p>On the client side, Apache ActiveMQ Artemis maintains a single, "global" +static scheduled thread pool and a single, "global" static general thread +pool for use by all clients using the same classloader in that JVM instance.</p> +<p>The static scheduled thread pool has a maximum size of <code>5</code> threads by +default. This can be changed using the <code>scheduledThreadPoolMaxSize</code> URI +parameter.</p> +<p>The general purpose thread pool has an unbounded maximum size. This is +changed using the <code>threadPoolMaxSize</code> URL parameter.</p> +<p>If required Apache ActiveMQ Artemis can also be configured so that each +<code>ClientSessionFactory</code> instance does not use these "global" static pools but +instead maintains its own scheduled and general purpose pool. Any +sessions created from that <code>ClientSessionFactory</code> will use those pools +instead. This is configured using the <code>useGlobalPools</code> boolean URL parameter.</p> + + + </section> + + </div> + <div class="search-results"> + <div class="has-results"> + + <h1 class="search-results-title"><span class='search-results-count'></span> results matching "<span class='search-query'></span>"</h1> + <ul class="search-results-list"></ul> + + </div> + <div class="no-results"> + + <h1 class="search-results-title">No results matching "<span class='search-query'></span>"</h1> + + </div> + </div> +</div> + + </div> + </div> + + </div> + + + + <a href="libaio.html" class="navigation navigation-prev " aria-label="Previous page: Libaio Native Libraries"> + <i class="fa fa-angle-left"></i> + </a> + + + <a href="logging.html" class="navigation navigation-next " aria-label="Next page: Logging"> + <i class="fa fa-angle-right"></i> + </a> + + + + </div> + + <script> + var gitbook = gitbook || []; + gitbook.push(function() { + gitbook.page.hasChanged({"page":{"title":"Thread management","level":"1.51","depth":1,"next":{"title":"Logging","level":"1.52","depth":1,"path":"logging.md","ref":"logging.md","articles":[]},"previous":{"title":"Libaio Native Libraries","level":"1.50","depth":1,"path":"libaio.md","ref":"libaio.md","articles":[]},"dir":"ltr"},"config":{"plugins":[],"styles":{"website":"styles/website.css","pdf":"styles/pdf.css","epub":"styles/epub.css","mobi":"styles/mobi.css","ebook":"styles/ebook.css","print":"styles/print.css"},"pluginsConfig":{"highlight":{},"search":{},"lunr":{"maxIndexSize":1000000},"sharing":{"facebook":true,"twitter":true,"google":false,"weibo":false,"instapaper":false,"vk":false,"all":["facebook","google","twitter","weibo","instapaper"]},"fontsettings":{"theme":"white","family":"sans","size":2},"theme-default":{"styles":{"website":"styles/website.css","pdf":"styles/pdf.css","epub":"styles/epub.css","mobi":"styles/mobi.css","ebook":"styles/ebook.css","print":"styl es/print.css"},"showLevel":false}},"github":"apache/activemq-artemis","theme":"default","githubHost":"https://github.com/","pdf":{"pageNumbers":true,"fontSize":12,"fontFamily":"Arial","paperSize":"a4","chapterMark":"pagebreak","pageBreaksBefore":"/","margin":{"right":62,"left":62,"top":56,"bottom":56}},"structure":{"langs":"LANGS.md","readme":"README.md","glossary":"GLOSSARY.md","summary":"SUMMARY.md"},"variables":{},"title":"ActiveMQ Artemis Documentation","links":{"home":"http://activemq.apache.org/artemis","issues":"https://issues.apache.org/jira/browse/ARTEMIS","contribute":"http://activemq.apache.org/contributing.html"},"gitbook":"3.x.x","description":"ActiveMQ Artemis User Guide and Reference Documentation"},"file":{"path":"thread-pooling.md","mtime":"2017-09-08T01:26:53.000Z","type":"markdown"},"gitbook":{"version":"3.1.1","time":"2017-09-14T19:42:32.953Z"},"basePath":".","book":{"language":""}}); + }); + </script> +</div> + + + <script src="gitbook/gitbook.js"></script> + <script src="gitbook/theme.js"></script> + + + <script src="gitbook/gitbook-plugin-search/search-engine.js"></script> + + + + <script src="gitbook/gitbook-plugin-search/search.js"></script> + + + + <script src="gitbook/gitbook-plugin-lunr/lunr.min.js"></script> + + + + <script src="gitbook/gitbook-plugin-lunr/search-lunr.js"></script> + + + + <script src="gitbook/gitbook-plugin-sharing/buttons.js"></script> + + + + <script src="gitbook/gitbook-plugin-fontsettings/fontsettings.js"></script> + + + + </body> +</html> +
