Dear Gurus,
My understanding is
On 64 bit solaris 8 swap size can be more than 2gb (in 32 bit solaris 8 - the
os can address only the first 2 gb of the swap even if it is more).
I cannot find anything in sun web site/sun manuals that specifically says this
- all I found closer to this in the swap man page
"Only the first 2 Gbyte of a block device larger than 2 Gbyte
in size can be used for swap in swapfs on a 32-bit operating
system. With a 64-bit operating system, a block device
larger than 2 Gbyte can be fully utilized for swap up to 2
**63 -1 bytes. "
What does the 2 **63 -1 bytes mean - does it mean 2 to the power of 63 and
subtract -1 - that much bytes is the max swap size.
Can somebody clarify.
Thanks, NR
