[jboss-jira] [JBoss JIRA] (WFCORE-2066) Kill and destroy operations on the server-group

[ https://issues.jboss.org/browse/WFCORE-2066?page=com.atlassian.jira.plugi... ] Brian Stansberry commented on WFCORE-2066: ------------------------------------------ [~ahoffer] Re: the difference between 'kill' and 'destroy' here's a good summary from [~claudio4j] that I saw: {quote} About the difference between kill and destroy: Short answer: "destroy" calls the internal syscall "kill -9" from native JDK. "kill" calls the command line "kill -9", if it is not available, it internally calls the previous "destroy". If the user just wants to forcibly terminates the process, use "kill" kill: If there is a "kill" command on the OS (unix has "kill", windows has "taskkill"), this command will be called to forcibly kill the process with kill -9 (SIGKILL on linux) and /f (windows). If the "kill" command is not available on the OS, then the "destroy" is called on the process. destroy: JDK provides an implementation to forcibly destroy the process, it will vary on each OS, on linux it call "kill" kernel api (the same as the above kill command) with SIGKILL signal, this is the same as calling the kill -9. {quote} I mildly regret that we have both 'kill' and 'destroy' as the distinction is quite esoteric. It's one of those things from back in the early history of AS 7 that still lives on for compatibility reasons. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
