[Performance Tuning] - Re: Best JVM memory size?
by jerrynolan
Peter,
I'm a bit confused by your answer, that if you have 1 gig of ram on a box it's ok to set the heap to 1 gig. Through reading your other postings I know that you have coded your own JVM based on Sun's source, so you know your stuff. And I know that you know the heap is just the new and tenured gen, not the whole JVM. Hopefully you can clear something up for me.
We run JBoss on Solaris. I have a basic formula that I use for my JVM memory calculations which is:
Total JVM memory footprint = JVM housekeeping + heap + permgen
In the formula above:
* JVM housekeeping (this is my own stupid term) = native code + JVM runtime data (code cache, etc.).
* heap = new gen + tenured gen
* permgen = permgen
When I run a prstat on the JBoss pid, what I see for SIZE is Total JVM mem footprint. I can do my little calculations with stats that I get from jmap -heap and come up with consistent sizes for JVM housekeeping across our boxes, depending on the particular deployment (and other things like # of threads).
In our case, we pre-allocate (set min=max) for heap and permgen.
I haven't yet found a option specifically for setting memory for the native code or runtime data, I don't know if anyone would want to.
Anyway (there really is a question buried here :), if you have a 1 gig box, preallocate 1 gig for heap (new and tunured), preallocate 128 or whatever for perm, knowing that the native code and runtime data might want 200 or 300 meg, aren't you going to be living in swap city?
I'm going to have to test this out. I've been leaving 500 meg free on our Solaris boxes for the OS and the monitoring stuff the network guys run.
Thanks,
Jerry

[Management, JMX/JBoss] - FileNotFoundException for some files inside SARs
by carloss
Hi. I'm trying to deploy quartz using a SAR. If I unzip the contents
of the SAR to a directory under the deploy directory, it works
fine. But if I try to just copy the SAR file, it cannot start because
it has problems finding the quartz-jobs.xml file, I suppose because it
is inside a zip file. Which is strange, because I'm currently using
org.jboss.security.auth.login.DynamicLoginConfig to have a SAR that
tries to load an XML file inside the login SAR, without problems.
The stack trace is

Is there something wrong in what I'm doing? Is it a bug? By the looks
of the top of the stacktrace it does not seem to be a Quartz issue.
One workaround that I can think of is instructing JBoss to always
unzip the SAR, but I haven't found a way to do it.
Thanks,
Carlos
