RE: 24X7 deployment tips
Oh! Thanks Now I realise that in some appservers/ tools changing the WAR file does not need restarting and Changing the EJB requires restarting the server. So it is the same case here then :-) Regards Rajaneesh -Original Message- From: Phillip Qin [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 12, 2005 8:16 PM To: 'Tomcat Users List' Subject: RE: 24X7 deployment tips Non-clustering.

[OT] RE: 24X7 deployment tips
Ah good old memory leaks, I see more and more messages regarding this although thankfully I have never experienced it myself. The reason this is off topic is that I was wondering if anyone has ever found a way of recovering leaked memory, without restarting the JVM?

RE: 24X7 deployment tips
Hi Sunil, I think they keyword for your scenario is clustering. Running multiple syncronised applications and databases allows you to take down servers during quiet periods and still maintain a service via the other servers whilst they are upgraded one by one. Saying that I have worked on global .coms that always allow for some down time during large releases / maintenance. It is not going to be easy but I am sure you appreciate that. One more thing that may cause a headache is session persistence under some Tomcat clustering models. Thats all i can think of but i'm sure you will get better advice than mine.
