heap size in JavaOPTS


Post reply

Can you set the heap size in JAVA_OPTS to however much mem you want or is there a limit ? Ie; xport JAVA_OPTS="-Xmx4096m -Xms4096m"
how much memory do you have?
8 gigs =)
64 bit system?
Yes
64 it OS?
and 64 bit OS?
Yes
then it ougth to work... does your java app really need that much memory?
Which 64bit OS?
Why do you immediately need a 64bit system to address >4GB of memory? :-\
Just for my personal knowledge is there a limit if it were 32 bit os ?
Yes there is
kadamat, 32 bit pointers give you access to how much memory?
4 gb ?
You can't address more than 3Gig on X86 Infact once you elinate kernel stuff and some other things, it's close to 2gig
optomeb, no, i'm just trying to tweak things and i was curious
optomeb, 16bit pointers gave you more than 32K addresses on the old x8086 CPUs.
AmeliaR, more than 4 GB actually... and that is not really true either with PAE you can use 64 GB
Not in one application you can't
