We can start more than one WSO2 Carbon (WSO2 ESB, WSAS, G-reg, GS, Mashup, IS, BPS, BRS, BAM, DS) instance by updating the transport configuration given in mgt-transport.xml (or transports.xml in 2.X series) as explained in here . Suppose, you need to start multiple carbon server instances as windows services instead of regular wso2server.sh executable. Then, there is an additional setting which has to be configured. Find wrapper.conf file inside CARBON_HOME/repository/conf Locate "Wrapper Windows NT/2000/XP Service Properties" section Update the Name of the service and Display name of the service in each instance as follows # Name of the service wrapper.ntservice.name=WSO2Carbon # Display name of the service wrapper.ntservice.displayname=WSO2 Carbon
