Re: Two instances of Tomcat with Formula 1 Software(E-spreadsheet)

[Mike W-M]

I haven't any experience with this particular scenario, but I'm not going to
let that stop me!

I guess the two instances must be running in separate "java" processes (and
that's probably fine, since I seem to be able to start up two JDevelopers at
once!), so

a) Does Tomcat2 give the same failure if Tomcat1 isn't running?  Or if you
try and run the report in Tomcat2 first, does Tomcat1 then fail?
b) Is there any chance they're configured differently?  Does this formula1
thing have a config file or setting that you've forgotten to copy across?
Maybe a spill-to-disk / virtual-memory setting?  Do any "relative paths" in
both instances resolve correctly?
c) Is there any chance that they're conflicting when trying to access the
same (absolute) resource?  Files?  Databases?

Okay, I'll stop "helping" and get some sleep...

Mike.

Hi Folks,
  Thanks to Ben and John on their inputs,But second instance of
Tomcat(tomcat2) still errors out when it tries to create a report with
Formula 1 software with Java.Lang.Out.Of.Memory error --though i increased
the Heap size upto upper limit of 1 GB.The system has total 2GB of Memory
.Everything else in the application in tomcat2 instance works fine.But that
Report part is a Crucial part of the Apps.
Is anyone using Two Instances of Tomcat on the same server with Formula1
s/w.Guys any help on this will be greatly APPRECIATED.
Configuration :
Red Hat Linux 7.0
Apache 1.3.12
Tomcat 4.0.4 -Two instances i.e  tomcat and tomcat2


Regards
Sameer

Sounds to me like that application isn't a very well-behaved application.
We have many Tomcat instances (more than 10) on 2GB of RAM with no problems.

Frankly, with Dell selling IDE-based servers around the $400 mark (tower,
not rack), the easiest and cheapest thing to do might be to just buy another
piece of hardware and throw some RAM at it...for less than 10 hours of time
at $100/hour, you can be done with this.  Especially if you have no control
over this other application's behavior.

If you've spent more than 6 or 7 hours trying to fix this, I know which
choice I would make.

John

OutOfMemoryError is a bad error description in java. It can mean any of 
the following:
- Actually ran out of memory
- Hit max # of threads allowed to run
- Ran out of file handles - File handles include open files AND sockets
- (?) Your JVM is bigger than the max process size allowed
- Other things I don;t know

There are tons of messages about dealing with all the above in the 
archives or google.
