Advise Heap Size vs JVM

by Rich Tretola :: Rate this Message:

Reply to Author | View Threaded | Show Only this Message

We have an appplication that is running on CFMX6 under a JRun
instance.  There are 5 other instances of CFMX6 on the box and the
physical memory is 4gb ram.  The 5 other instances are not very busy
but the main one is and has been chewing up memory.  We increased the
heap size to 768mbs and are thinking of going to 2gb.  This heap is
currently for the entire JRun server as there is only 1 jvm currently.
 So my question is:

Would it be better for us to add a dedicated JVM to this instance and
give it a gig or so of heap size or should we just increase the
overall heap on the single jvm ?

Thanks,
Rich

How do you have '5 other instances of CFMX6 on the box'  setup?
Sounds like you have CF Enterprise setup in mulit-server install.  Are
each of these 5 instances using a seperate JRun server instance or the
same one?  curious.

As for tuning I suggest peaking at

Yes,  there is 1 install of JRun with 6 server instances each with its
own cfmx6 deployment.

ok, if you have 6 JRun instances each running CF, then you have 6
individual JVMs running.  Each JRun server instances gets its own JVM
instance.

That is not what my server admin is saying.  He claims that they all
share one jvm.  I'll ask him again.

Doug is right.  Every individual JRun/CFMX server instance fires up its
own individual JVM.  Six JRun server instances means six instances of
the JVM.

So is it possible to set the heap size per jrun instance?

Yes, In the Jrun JMC, you can drill down each Jrun Server's settings.  In
the JVM settings there is a max heap size setting allong with parameters you
can pass to the VM.

Re: Advise Heap Size vs JVM

actually, the JMC manages only the default JVM config that will apply
to all JRun instances.

http://livedocs.macromedia.com/jrun/4/JRun_Service_Pack_1_Guide/4relnotes7.htm
this has a little blurb about setting up multiple jvm.config files.  
You will need a one-to-one mapping of config files to server instances
if you want to tweak all of them idividually.

I usually name mine jvm.config_<servername>.  You can just copy the
default one as a template.

Yes, In the Jrun JMC, you can drill down each Jrun Server's settings.
In

the JVM settings there is a max heap size setting allong with parameters
you

can pass to the VM.

So is it possible to set the heap size per jrun instance?
