  • What the ":reload" operation does in EAP ?
  • Is there any differences between the ":reload" operation in domain mode and standalone mode?
  • Does jvm shuts down when reloading the server through jboss-cli ":reload" operation?


Difference between Reload & Restart:

  • For Domain mode: In case of ":reload" command on Host Controller , will reload (stop & start) all the services which are running on a Host-controller including the JBoss process associated with that host controller, however in this case the PID of the Host Controller is not killed, which means Host-controller process never dies rather only the services associated with it are re-started.

  • For Standalone mode: The standalone JBoss process will not be killed rather the services which are running on that JBoss instance will be reloaded (stopped & started). So you will see the same PID for the JBoss is maintained before & after the ":reload" operation.

  • There is also an option available to reload using "admin-only" mode.

  • Here admin-only means It will set the server's running type to ADMIN_ONLY causing it to open administrative interfaces and accept management requests but not start other runtime services or accept end user requests, For more info see [1].

I believe what is documented above as:

also if you are using the bare reload, it seems like this is appropriate:

reload --admin-only=true
