So you would need 64 Bit versions of those libraries which are coming from BMC. I would be interested in the info whether they exist as well :) I now run ARS 7.6, with the newest Mid-Tier 7.6 on my test server and it runs with 64 bit Java :) But now it uses a lot of CPU. Googled it, and saw people having CPU-usage issues with ESX Vmware and Tomcat.

Actually, Java can compress pointers even under a 64-bit environment to save space, so in that way, it might not balloon memory use. :p In my experience, Java does not use significantly more CPU than programs of similar (and reasonable) complexity written in other languages: the problem is that most people compare apples to oranges. They will compare a Hello World program in Java and C and show you that the Java program requires 6MB of heap just to get going and takes have a second to run while the C program requires no heap whatsoever and runs instantaneously. Yes, that's true. However, Java wasn't built to run trivial things like Hello World. Once you get into significant complexity, the playing field levels quite dramatically. That's why, when writing programs, I choose the technology that is appropriate for the situation instead of running to one or another language/environment all the time. For production operations, we use Java for all of our web apps, but we have lots of utilities written in Perl, PHP, Bash scripts, and the occasional C program: the right tool for the right job IMHO. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkyvOdMACgkQ9CaO5/Lv0PAfdQCffhIakLmPycvlseZ2Y28B58vM cjkAnRzv6M+sCbZzxrqmGChF255GZFNY =2z2f -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Not sure what can be done on a 64-bit Windows, since the expectation is that serious apps will be using 64-bit processes. - Chuck Chuck is right on the limits above. I've managed to eek out 1536Mb on most of my 32-bit installs using Java 5/6 and Tomcat 5.5 (we've not moved to TC6 yet - next project). Even with the 3Gb option set on the 32-bit Windows, I couldn't get much higher (search archives for exact number). I haven't found any way comparable option for the 32-bit environment on the 64-bit O/S versions, but then again, I haven't looked. If I have 64-bit O/S, I use 64-bit Java. One thing to note that Chuck mentioned, is there are other factors involved in all that memory management. Beyond any native code requirements, there are other things like PermGen size settings that might affect the max memory size. I recently had a baffling problem when trying to increase my PermGen space. On one system, I had increased the MaxPermGen setting to 256Mb and everything was fine. When I went to an identically configured machine, Tomcat would not start with that large a setting. I could get 160Mb to startup. I didn't try any higher values to see what the max was, I could just tell that I was hitting some limit. Then I noticed that there was a slight variance in the Tomcat configs. The second machine had a higher Max Memory Pool (Heap) than the first by about 512Mb. So there is some tradeoff between PermGen space and Heap. Check all the other settings that BMC said you needed to set, and see if there is something there stealing the available space. Currently, I monitoring the two systems to see if there is an optimal PermGen vs. Heap setting for their specific loads (which are different). __ Confidentiality Notice: This Transmission (including any attachments) may contain information that is privileged, confidential, and exempt from disclosure under applicable law.

RE: apache-tomcat-6.0.29 will not start with more then 1024mb memory assigned - windows
Chuck I don't want to restart the memory allocation wars, primarily because I'm not totally sure on my stance, but I'm pretty sure that PermGen is not part of Heap. I'm particularly basing this on what I'm currently seeing in the Memory tab of jconsole. It breaks up memory into Heap and Non-Heap sections. It further breaks those down into the following: Heap: PS Eden Space, PS Survivor Space, and PS Old Gen Non-Head: Code cache and PS Perm Gen Now, when I click on the Heap section, it shows a Max very close to my -Xmx setting. It's hard to say if equal, since I specify in Mb and it reads in kbytes, but it does appear lower than I would expect. For example: a -Xmx768m ends up with a setting of 757,312 kbytes. The Non-Heap section max is always higher than my -XX:MaxPermSize setting and appears to be a total of the Code Cache size and the PS PermGen size. Since I'm not specifying a value for the Code Cache it is consistently 32,768 kbytes. For a MaxPermSize of 256M, I get a Max reading of 262,144 kbytes. That is exactly 256 * 1024, so you'd think that my Heap of 768m would generate a Max value of 786,432 kbytes, but you end up with a value smaller by 29,102 kbytes. I wonder where that went? I think I know. First, the Max when you click on Heap isn't accurate. If you add up the total of the 3 spaces, you get much closer to the -Xmx setting, but are still a little short. As I recall, the Survivor Space is really two spaces used alternately during GCs, and surprisingly the missing amount is almost exactly the same as the Survivor space number. However, I'm still stumped as to why the Max Heap reading is so much lower than the -Xmx setting you have you believe, or a manual totaling of the 3 segments shows it to be. Of course, it appears that the max readings for at least the Eden and Survivor spaces can change over time, so perhaps there is just reserved space in case those sections need to expand a little. In about an hour of monitoring, the Old Gen max size never budged. I will agree with your assertion that it all has to be allocated contiguously. Also, please note these are all numbers for a Java 5 implementation, though Java 6 (64-bit) shows the same patterns of allocation noted above. -Original Message- From: Caldarale, Charles R [mailto:chuck.caldar...@unisys.com] Sent: Wednesday, September 29, 2010 12:14 PM To: Tomcat Users List Subject: RE: apache-tomcat-6.0.29 will not start with more then 1024mb memory assigned - windows From: Jeffrey Janner [mailto:jeffrey.jan...@polydyne.com] Subject: RE: apache-tomcat-6.0.29 will not start with more then 1024mb memory assigned - windows So there is some tradeoff between PermGen space and Heap.
