Alfresco (alfresco + share) and client app are running on separate machines on their own servers (tomcat). Alfresco works properly, but client application cause too many open files problem in operating system (ubuntu linux). The limit was raised, but with an increase in app load increases the number of open files until the system crashes.</SPAN><BR /><BR /><SPAN>Is it possible to limit the number of open files by CMIS?</SPAN><BR /><BR /><SPAN>I'am using spring framework, alfresco 4.2, open cmis 0.7.0 and cmis session is singleton created as below:</SPAN><BR /><BR /><PRE class="language-none line-numbers"><CODE><BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Map&lt;String, String&gt; parameters = new HashMap&lt;String, String&gt;();<BR /><BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; parameters.put(SessionParameter.USER, user);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; parameters.put(SessionParameter.PASSWORD, password);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; parameters.put(SessionParameter.ATOMPUB_URL, server);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; parameters.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());<BR /><BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; SessionFactory factory = SessionFactoryImpl.newInstance();<BR /><BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; List&lt;Repository&gt; repositories = factory.getRepositories(parameters);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; session = repositories.get(0).createSession();<BR /><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN></CODE></PRE><BR /><BR /><PRE class="language-none line-numbers"><CODE><BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;dependency&gt;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;groupId&gt;org.apache.chemistry.opencmis&lt;/groupId&gt;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;artifactId&gt;chemistry-opencmis-client-impl&lt;/artifactId&gt;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;version&gt;0.7.0&lt;/version&gt;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/dependency&gt;<BR /><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN></CODE></PRE></BODY></HTML> Tue, 05 Feb 2013 08:23:57 GMT kotfilemon 2013-02-05T08:23:57Z Using CMIS cause too many open files system problem https://connect.hyland.com/t5/alfresco-archive/using-cmis-cause-too-many-open-files-system-problem/m-p/274672#M227802 HiI'am using alfresco and webapp client application using open cmis for communication.
