unable to allocate enough memory

moata_u · 06-20-2011, 03:46 PM

On SunOS 10 get an error when starting a large Java process with over 2Gb memory.

Code:

Error occurred during initialization of VM 
Could not reserve enough space for object heap

i have 32G memory !! , swap = 31G

Please any advice !!!

Java has a 2 gigabyte memory limit on its virtual machine, I'm afraid. Is the code your own? There is likely a better way to do things than reserving 2 gigs of memory...

That looks like a 32 bit limit. On Solaris 10 you should be able to run 64bit (assuming your HW supports it).
My work systems are 64bit and run 32 + 64 bit code.

Check with your Oracle manual or Oracle themselves to see if you have 32 bit or 64 bit Oracle.
Also, check Solaris

Code:

isainfo -kv

Incidentally, that works on SPARC chip; not sure about x86 but try it anyway.
Actually, see other options here http://www.unix.com/solaris/45780-ve...olaris-os.html

Also, google your processor chip & see if you've got a 64 bit chip.
