Hi everyone, I am reviewing a clustering implementation I have done and after reading the documentation for Tomcat 8, which is the version I am using (8.0.35 + Oracle JDK1.8.0_92) I ran into the distributable attribute.
I saw in my configuration the distributable="true" attribute is set at the Context container definition level rather than having a <distributable/> element in the web.xml of each web application in the cluster. I cannot find this attribute documented in the Context container documentation. Is it an omission or the attribute is deprecated or what? I also saw in this documentation page: http://tomcat.apache.org/tomcat-8.0-doc/config/cluster.html The Context element should specify the className="org.apache.catalina.ha.context.ReplicatedContext" in order to enable the Context replication. I am wondering if distributable="true" is equivalent to setting the className to the value above or not? If not, what is the difference? I am asking, because I did not set the className to this value and so far, it seems to work. What is the proper way with Tomcat 8 to setup the Context for clustering? I also saw the sample configuration in the Clustering HOWTO documentation ( http://tomcat.apache.org/tomcat-8.0-doc/cluster-howto.html) and the Interceptor MessageDispatch15Interceptor defined in this document is deprecated and MessageDispatchInterceptor should be used instead. Which make me doubt if this documentation is accurate or not. I found the deprecated class while searching for the different values for channelSendOptions. Here: http://tomcat.apache.org/tomcat-8.0-doc/api/org/apache/catalina/tribes/group/interceptors/MessageDispatch15Interceptor.html So, a little clarification would be appreciated.
