Hi
If the question is how to restart the Wildfly server in Virtual Appliance, the commands are:
start_im - start the IDM server
stop_im - stop the IDM server
restart_im - restatrt the IDM server
for more commands, please see here:
Administrating CA Identity Suite Virtual Appliance (vApp) - CA Identity Suite - 14.0 - CA Technologies Documentation
If the question is how to do that on a stand alone setup, you should run the standalone.bat/sh file under the bin directory, if you want to restart it, run the shutdown.bat/sh on the same directory and if it doesn't exist, kill the java process and start it again
Again, i hope i understood your question
thanks
Itamar
