I have been scouring the internet to find out how much memory a java process can take on a linux (red-hat) machine. ( I am not talking about heap; rather, the entire amount of memory taken up by the java Process)
I don't have permission to execute anything on that machine. So I can't simply execute a program that consumes memory until Out-Of-Memory condition.
However, I do have permission to check config files, etc. ( for example: I tried to execute cat /proc/meminfo, but I can't understand it; it appears that none of its results stand for the parameter I want to know about).
I have tried out a java program on a separate red hat machine - on which I do have permission to execute programs - and I was able to see java program grow up to around 3GB.
Is there some way I can find out how much memory a process can get ?

e.g. A Suse 2.4. 20 Linux system restricts the maximum size of a shared memory segment to 32 MBytes (the on-line documentation says the limit is 4 MBytes !) This limit must be changed if large arrays are to used in shared memory segments.
A process lives within a 4GB virtual address space. The limit mirrors that of a 32-bit pointer and is deemed 'virtual' because the address pointer does not refer to physical memory but is actually a logical address.
ulimit is your friend. Java processes are no different than any others. But if you can't even run ulimit -a, it's hard to answer your question.
