SUMMARY: increasing process avail mem on SPARC2

Here's what I needed to do:

I have a SPARCstation 2 running Solaris 2.3, and we have programs that
we develop in-house, but they need to access about 1.5--2 Gb of data
in memory. My little SPARCstation 2 tops out at 535 Mb, even though I
have more than 2 Gb virtual memory configured.

SOLUTION:

The SPARCstation 2 does not allow you to let processes take up more
than that 535 Mb 'hard limit'. That's a hardware limit, not software
(i.e. not related to Solaris.)

The engineer from Sun that I spoke to says the Ss2 runs a sun4c
architechture. The Sun SPARCserver 4/470 that we also have (4.1.3) is
running those programs fine, and has a limit of 2 Gb. It just so
happens that the Ss4 uses a sun4m architechture, which has a memory
limit of abiout 2 Gb.

So, basically, you can't do what I was trying to do.
