If no Tomcat java processes are running, skip to step 6. Otherwise, because the Tomcat JVM is not shutting down in the time you've allowed, you may want to force it to exit. Do another ps like you did in step 4.
If the Tomcat JVM processes remain, repeat step 5 until they're gone. If they persist, have your operating system kill the java process.
On Windows, use the task manager to end the task s. On all other operating systems, use the kill command to tell the kernel to kill the process es like this:. Usually, the shutdown process goes smoothly and Tomcat JVMs shut down quickly. But, because there are situations when they don't, the above procedure should always suffice. We realize this is not a very convenient way to restart Tomcat; however, if you try to cut corners here, you will likely not always shut down Tomcat and get errors due to the new Tomcat JVM bumping into the existing Tomcat JVM when you go to start it again.
Luckily, for most operating systems, there are scripts that automate this entire procedure, implemented as a "restart" command. The following outlines how to reliably restart Tomcat on Linux. If you installed the RPM package from this book, do:.
And, if you installed the JPackage. Be sure to check your logfiles for any startup problems. The following outlines how to reliably restart Tomcat on Solaris. As of this writing, the Blastwave package's init script does not contain any code to reliably restart Tomcat—it does not watch the processes to make sure that they came down all the way, nor does it try to force the processes down if they do not come down on their own.
Read the init script source and you'll see what we mean. So, it is up to the Solaris administrator to ensure by hand that the restart actually occurred. If you have Tomcat running as a Windows Service, you can restart it from the control panel. Either right-click on the service and select Restart from the pop-up menu or, if it exists on your version of Windows, use the Restart button near the upper-right corner of the dialog box see Figure If you have chosen to use the generic way to start Tomcat, there is no easy way to restart Tomcat in Mac OS X and the best solution is to call shutdown.
Then, just as described in the Linux section of this chapter, you would decide how long you will wait for Tomcat to shut down and take the appropriate steps, as outlined above. A simple way to see if Tomcat is running is to check if there is a service listening on TCP port with the netstat command. This will, of course, only work if you are running Tomcat on the port you specify its default port of , for example and not running any other service on that port.
You should see no output, meaning that Tomcat has shut down. Then, you may start it back up again, like this:. After waiting some seconds, check to make sure that Tomcat is running and listening on port again:. If you have chosen to use the automatic startup and shutdown scripts for Tomcat via Apple's launchd see the section " Automatic Startup on Mac OS X ," later in this chapter, for details about how to set that up , it's very easy to restart Tomcat simply by unloading the service and reloading it into launchd :.
You can restart the Tomcat 6 port by running:. That should reliably restart Tomcat. However, renaming these to your preferred conventions is only temporary, as the. You are better off getting used to typing catalina. That is false. The servlet specification does not preclude doing this, so it is OK to spawn one or more threads as long as the thread s are well behaved. This is often the rub, since webapp developers often report bugs against Tomcat that turn out to be caused by their own code running in a separate thread.

The point is mainly that you need to [run as an administrator]. As Bali C pointed out, you could do this from the search bar, or find Cmd in your start menu and [right-click], run as admin or if you are doing a scheduled process, make sure it is running as admin.
