- 24. Class Loading Customization o There are 4 in-built environment. o Tomcat – Minimal runtime (Tomcat) o Carbon – Tomcat + Carbon + Axis2 o CXF – Tomcat + CXF + Spring o JavaEE – Tomcat + TomEE o Users can add their own Class loading environments o Edit {carbon.home}/repository/conf/ tomcat/ webappclassloading-environments.xml file o
- 25. Class Loading Customization cont. o Configure per server or per application o {carbon.home}/repository/conf/tomcat/webapp- classloading.xml o META-INF/webapp-classloading.xml o Can provide mix of environment (e.g. CXF, Carbon) o To specify CXF/Carbon as the runtime environments users should have the following configuration <Classloading xmlns="http://wso2.org/projects/as/classloading"> <Environments>CXF,Carbon</Environments> </Classloading>
- 26. Lazy Loading and Resource Management o App servers usually run for a long time o Keeping inactive applications on memory for a long time, may affect performance o App server restarting can cause considerable amount of app downtime and affect availability o Resources such as memory, cache and processor time are expensive, hence need better resource management o Lazy loading and resource sharing mechanisms should not negatively affect end- user experience
- 27. Tenant Lazy Loading o When a request is received, an interceptor will assess request details (e.g. URL, session info) o Based on the request details, the interceptor will pick the corresponding Tenant from the tenant store o A Task will be running in the background to identify inactive tenant(s) o When a tenant is inactive for a predefined duration (e.g. 30 min), the tenant will be un-loaded Request Origin Request Tenant Identified by Interceptor Tenant Loaded Max Tenant Inactive Duration Elapsed Identified Tenant Tenant Un-loaded YES NO
