yes, you'd need enough space...i was just thinking, though....if you have 3
gigs of ram, you'd need a large file enabled filesystem....whatever happened
to dumping to tape?

But you would still need a filesystem = total system memory based on the
practice here, yes ?

my dump device dumps to a file in /var/adm/ras, not paging device.

What about the thinking that "paging space should be = to total memory in
the event of a system dump."

That is something I am hearing at my assignment now. Not something I
practice, but they are talking about it.

So less than 1GB, use the old formula, >1GB, make it half real memory?

i think the rule changes once you exceed a gig of real memory

IBM support told me to make my Total Page Space half of the total Real
Memory.

Subject: paging space

Hi,

What's the current accepted standard for configuring paging space?
According to my 4.3 System Administration Redbook:

Total paging space = 512MB + (memory size -256MB) * 1.25MB

but I seem to recall reading this is significantly out of date for newer
servers. Any suggestions?
