One of the developers may clean up my answer if I'm off a bit but I'll try to explain. The sandbox is an isolated build of your entire current setup. It copies your build into it and then runs the update scripts against this "virtual" build. If there are any errors, the only thing that is broken is the sandbox, not the production build. Once all of the patches are applied to the sandbox build and there are no errors, it tells you the build was clean. Then it asks if you want to apply it to the production build. At that point, when you say yes, it throws the built sandbox system "over the wall" into the production folders.
This process does 2 things, first, it safely builds the patches into the virtual build without jeopardizing the production build. Second, it makes the downtime VERY short (Less than a minute) while it applies the sandbox build into production. If you have a lot of patches to apply, the sandbox build can take a while. Mine last night was pretty far out and I think I had every QMT module patched, it took about 45 minutes to build and apply the sandbox but only 45 seconds to copy into production. Thus my QMT was only down for 45 seconds. The copy sandbox vs unionedfs sandbox is a huge improvement. In the past, it would actually COPY your entire QMT system into a sandbox folder. Just this, BEFORE applying the patches took over an hour. Now the unionedfs does some magic that I'm not fully clear on but they are links to the files and not copies of them so the sandbox build takes only a few minutes. -----Original Message----- From: Anil Aliyan [mailto:[email protected]] Sent: Saturday, May 02, 2009 9:27 AM To: [email protected] Subject: [qmailtoaster] About Unioned Sandbox Hi, I want to know bout Unioned Sandbox. What does actually a sandbox do? When we run qtp-sandbox script and it prompts for "Would you like a unioned sanbox (quicker, smaller) [y]/n:" what difference does it actually makes???
