Hello, I have searched inside TOMCAT (for the moment version 10.1.x but seems to be present in all versions) how to stop TOMCAT during INITIALIZATION phase and I can't find any method how to do it.
Tomcat seems to have 3 ways to stop it: 1. Sending SHUTDOWN command over the control port socket (the most traditional one) 2. Sending SIGTERM signal to java process because I see that org/apache/catalina/startup/Catalina.java registers a java shutdown hook that basically stop's the server container 3. calling manager jmxproxy via HTTP and invoke stop on server container The problem of solution 1 and 2 is that these ways are available only after initialization of toncat is complete (the second one I never been able to use it but seems to me from code that is available only after initialization when is logged the message that says " INFO [main] org.apache.catalina.startup.Catalina.start Server startup in [26102] milliseconds"). Solution 3 is also available after initialization because manager web application is scheduled to startup after our web application and tomcat seems to pause http requests until initialization is complete. So I am not able to send any signal to shutdown tomcat during this initialization phase or I can't figure out how to do it. The reason we want this is as follows: Our application consists of a TOMCAT instantance that run's inside our WAR web application together with manager, host manager and default ROOT tomcat delivered web applications (the root application is modified to redirect to our web application). Our war application takes aprox 20 - 30 seconds to startup and the majority of time is spent inside few servlet context listeners and stops quickly in gracefull manner. We also have some custom made wrapper bash scripts that start / stop tomcat like this: - the start script delegates the start procedure to bin/catalina.sh tomcat script with run parameter (after setting environment and other things) - the stop script delegates the stop procedure to bin/shutdown.sh tomcat script (after setting environment and other things) Due to the fact that initialization takes a visible long time, it is possible to need to stop tomcat in this phase for the following reasons: 1. the administrator wishes to interrupt this initialization 2. the operating system is shutdown gracefully during initialization of tomcat and tomcat, like any process, need to start a shutdown during any phase Our question is: 1. It is possible to stop tomcat during initialization phase? 2. If yes how and if not are any plans to implement it in future versions? It seems to me that my solutions for now are: 1. sending SIGKILL signal to tomcat (this is very risky to me because stopping like this in the middle of something may corrupt data - but this situation is any way possible so I have to handle it) 2. wait for tomcat initilization procedure to finish and then trigger the shutdown since we can do something in our wrapper scripts Do you see any other possible solutions? Thanks. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
