LiveCycle runs inside a container(J2EE application server) in the form of EARs that are deployed on the J2EE Application Server(JBoss, Websphere,Weblogic) being used.As long as the Application Server is running the LiveCycle services be available. If application server is down and end users can request form/data, then it could be due to browser caching .
P.S. - Configuration Manager is only used for deploying EARs, DSCs/LCAs on LiveCycle container and other configuration, after installation.
