RE: [OT]Re: Is better one or more Tomcat instances per machine
| From: Christopher Schultz [mailto:[EMAIL PROTECTED] | Sent: Wednesday, 14 March, 2007 12:05 | | Perhaps, but the JVM actually refuses to start right away. In my eat | all my memory tests, I was able to eat around 1.6GB before I brought my | machine to a crawl. It took more than a minute for my terminal to | respond to a CRTL-C (or perhaps the kernel killed my process for virtual | memory exhaustion). That process took at least a minute. I imagine that when the JVM calls [cm]alloc, one of the first things alloc() does is call sbrk() to expand your process' memory space. That'll fail right away if you don't have enough VM available. If you're expanding the arena in stages, then you won't die until you hit the limit. If you want to hit the limit faster, double your allocation size each time. Once you hit the limit (malloc() should return (void *)-1), halve your allocation unit size and try again. Keep halving and allocating until you get success. Keep halving and allocating until your allocation size is less than a page. You might also want to see what results you get by just calling realloc() with increasing sizes. I may try this myself when I get home (don't have a Unix box handy here), but I'm running 64-bit Solaris on an Opteron, so I don't know if my results will help. | Then again, I was allocating my memory in 50MB chunks and then writing | to them. Perhaps Sun's JVM on Linux allocates the whole chunk of memory | at once (which doesn't do anything on Linux glibc) and then writes to | the last page to see that it can be used. That doesn't seem right, so | there must be some other voodoo going on here. What doesn't seem right? Remember, the heap isn't a bunch of empty pages; you have to set up your block list, then initialize PermGen and other system spaces. It's entirely possible that the JVM needs to access the last page as part of initializing itself. I know nothing about JVM internals and not much about Linux, but I used to be a fair VMS hacker, and I did learn a bit about virtual memory implementation (all probably obsolete if not downright wrong nowadays...) | I have a buddy with a 128MB ppc-Linux 2.6 box with 512MB swap | and java installed. I had him check, and his bombs (with a jvm panic!) | when asking for even 512MB. So, it looks like physical memory and swap | also have an effect. I would have expected the JVM to simply attempt to | allocate the memory and use it. Which is probably exactly what happened. The panic arose when the JVM attempted to initialize the heap, and found out that the kernel had lied to it about there being 512M available. Maybe the PPC kernel does some kind of optimistic allocation, where it marks the process size appropriately and just uses an allocate-on-write mechanism to permit the process to use pages up to the stated memory limit. This would permit the kernel to over-allocate VM on the pretext that processes that request large amounts of memory often don't use much of it. Kind of a VM-kiting scheme, where the kernel allocates memory it doesn't have in the hopes that when the requesting program goes to use it, some other program will have exited and freed up some space.

a table by just blithely calling
tbl.appendChild(document.createElement(tr)) -- even through Mozilla
accepts it and does what you might expect, it's wrong (that code will append
a new child to the *table*, so it'll be treated as a second table body, so
it won't show up) So use the W3C standard of
tbl.lastChild.appendChild(document.createElement(tr)), like IE enforces.
Sorry, I just get a little twitchy when people start mooning over Mozilla's
W3C compliance. Sure, it's pretty compliant, and yes IE is a festering
cesspool, but don't get suckered into the Well, it works on Mozilla/FF/NS,
so it *must* be W3C compliant... trap. Every browser has it's little
departures from the spec, keep your eyes open and test with every (version
of every) browser you can get your hands on.

RE: web application - student need help
Hmmm, interesting, a lot of the articles I remember reading don't seem to be available anymore. Too bad, there were some good war stories. They've probably all been pulled and reworked into Learning Tree Building Scalable Web Architectures courses. Most of what I could find about new Web 2.0 sites seems to be all touchy-feely user experience-oriented stuff, no tech details on what it actually takes to generate a tag cloud or keep response time beneath the magic 3-second threshold. Here's some stuff I did manage to come up with: A description of Slashdot's current setup (actually a few years old): http://slashdot.org/faq/tech.shtml#te050 Here's a story on Slashdot asking basically the same question the original poster did: http://ask.slashdot.org/article.pl?sid=05/05/26/1433202 A description of the growing pains of Anandtech (another geek site): http://www.anandtech.com/printarticle.aspx?i=2136 A PDF showing the infrastructure of Flickr: http://www.niallkennedy.com/blog/uploads/flickr_php.pdf Probably the most relevant -- a post describing how one site survived a Slashdotting (with a 466MHz Celeron on a DSL line): http://devnulled.com/content/2005/07/surviving-a-slashdotting-with-a-celeron -466-my-slashdot-experience/ | -Original Message- | From: Ross, Scott [mailto:[EMAIL PROTECTED] | Sent: Monday, 08 January, 2007 10:24 | To: Tomcat Users List | Subject: RE: web application - student need help | | Tracy Nelson. | Out of curiosity, can you point to some articles relating to the growing | pains you mentioned regarding Slashdot, Granddaddy and MySpace? | | Thanks | Scott Ross | | -Original Message- | From: Nelson, Tracy M.
