Hi.
Does anyone know how to add swap space on a System V Release 2 system?
In particular, on an emulated AT&T 3B1. The kernel is S5R1 or S5R2
vintage.
I don't see any commands with 'swap' in their names.
Thanks,
Arnold

A little bit of Google Groups trawling turned up this:
https://groups.google.com/g/comp.sys.att/c/8XLILI3K8-Y/m/VxVMJNdt9NQJ
But I don't have one of those systems, so I have no way to verify.

I don't know about 3B versions, but on Dell SVR4 on 86Box
(https://notes.technologists.com/notes/2021/01/19/koko-dell-unix-sustainable/)
I see
/ # apropos swap
swap(1m): swap - swap administrative interface
swapctl(2): swapctl - manage swap space
...
I've never tried to adjust swap, just trust that our install did the
right thing. On this system, freshly booted, with 32M memory and 5G
"disk", I see
/ # swap -l
path dev swaplo blocks free
/dev/swap 0,2 0 98784 90960
Here's the beginning of man swap:
NAME
swap - swap administrative interface
SYNOPSIS
/usr/sbin/swap -a swapname swaplow swaplen
/usr/sbin/swap -d swapname swaplow
/usr/sbin/swap -l [ -s ]
/usr/sbin/swap -s
DESCRIPTION
swap provides a method of adding, deleting, and monitoring the system
swap areas used by the memory manager. The following options are
recognized:
-a Add the specified swap area. swapname is the name of the block
special partition, e.g., /dev/dsk/0s2 or a regular file. swaplow
is the offset in 512-byte blocks into the partition where the
swap area should begin. swaplen is the length of the swap area
in 512-byte blocks. This option can only be used by the super-
user. If additional swap areas are added, it is normally done
during the system start up routine /etc/rc2.d when going into
multi-user mode.

That's very helpful!

But I do - in emulation. I will try this out shortly.
Thanks!

Yes - I was looking for something like that. SVR4 is after a lot of
additional kernel technology from Sun. The S5R2 vintage system seems to
have had the swap device configured in at kernel compile time. :-(
Thanks,

SIMH has 3b2 emulation...
Much of the work was documented here:

I think he was looking for 3b1 which was a 68K of some sort. The 3b2
was some weird processor out of labs. Found it:
