Starting and Stopping Server InstancesRef: http://wikis.sun.com/download/attachments/211392120/admin-fs.html#pl The one-pager simplifies the process of starting and stopping servers. This article goes into a bit more depth. A Process View of Starting (non-native)
The startup procedure is quite complex. It is extremely difficult to debug because of the extra JVM in the middle. The startserv script is potentially confusing to a user and is vulnerable if edited. For V2, the middle JVM will be eliminated. The instance JVM will be started directly by asadmin or by other running Java programs.
1. Take over Middle VM responsibilities 2. Modify startserv script
ShutdownThis is a ripe area for improvement. The stopping of instances is far too complex. The starting code is super-complex and needs to be because the instance has to run in an elaborately configured JVM environment. E.g. special JVM options have to be parsed from domain.xml and used to start the instance-JVM. Stopping the instance, conversely, should be much simpler since its job is to shutdown running objects. It is not neccessary and a waste of time and resources to build intricately configured JVMs to stop an instance. This is a classic example of questionable code reuse. The super-complex starting code was reused to stop instances. Here is an example of how this approach can bite: https://github.com/javaee/glassfish/issues/949. We propose simplifying stop and undoing the common code between start and stop.
