Re: Safe to move tomcat directory while tomcat running?
I would be doing it on red hat. Would it just be easier to email all the users and say its down for maintenance and then just move it?

Re: Safe to move tomcat directory while tomcat running?
Ok thanks what i meant is that the tomcat directory is in ~/tomcat6/apache-tomcat-6.0.20/ and i need to move it to my home directory ~/. Basically was it safe to do it while tomcat is still running.

Generally, no, you can't do that - if your not-quite-English question has been understood. It all depends on what you mean by move the tomcat directory with in my user. Even renaming the directory may cause problems. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: Safe to move tomcat directory while tomcat running?
On unix (posix, linux) systems you can move anything even when in use. Files that are open will remain open, and the application will continue to use them. Problems will arise when the application attempts to open new files, because then they have to be at the expected location. If you really want zero downtime, you can set up softlinks to make the program believe that everything is still in its old location during the transition phase. On the other hand, if you prepare it well, you can stop, move and start in a matter of seconds, and most users will never notice it was down. And the risk of the whole thing crashing down because of some peculiarity in the application due to the unexpected move is probably big enough to want to avoid that situation.

Re: Safe to move tomcat directory while tomcat running?
Without stopping the JVM you want to change the files that the JVM is using? I wonder. Hopefully, you can copy the files to another location, if the application dont have any open inputstream. But the JVM current execution path will not change if you donot restart it.
