FYI Sparc/Solaris also has both 32- and 64-bit editions.

3000 MB free with 3000 MB max? That doesn't sound right. /Some/ of the
memory ought to be taken up by the JVM... but 3000 MB looks fine to me.

hi, thanks for your answer,  i think that i have to questions in solaris, is
a solaris sparc,  but, if the manager application show

Free memory: 3000 MB Total memory: 3000 MB Max memory: 3000 MB

then tomcat have 3000?,  if true then i can put 3 gb in my tomcat.

thanks and sorry for my english

Maybe. Most 32-bit JVMs can't actually give you 3GB of heap space.
You'll probably be limited to somewhere between 1.5 - 2.0GB. If you have
a 64-bit processor and OS, go with a 64-bit JVM and then you can get
/lots/ of memory.

I'm not entirely sure what you mean, here. Could you try to ask this
question in a different way?

That ought to give you a 1.5GB fixed (no more, no less) heap.
