The lack of a GUI on the Mac is certainly annoying. However, you can do
everything from a Mac that you can from any other platform with a little
work. The Codewarrior plug-in works well for most routine tasks
(edit/sync/etc). For the more complicated activities, the MPW tool works
just fine.
I'm not sure why you couldn't submit on the Mac. What symptoms/errors did
you see? Our development shop uses both Macs and PCs and we've had very
little trouble with Perforce, especially compared to VSS.

We're using:
Mac OS 9.0.4
MPW 3.5b2
p4 Rev. P4/MAC/99.2/14790 (2000/03/24)
And a startup file that sets:
# Perforce environment variables
set -e P4USER dair
set -e P4PORT ramone:1666
set -e P4CLIENT itchy
set -e P4EDITOR "LightWork:Projects:Perforce:Scripts:p4bbedit"
Where p4bbedit is a wrapper that opens BBEdit to edit changelists/etc.
You might want to try doing:
p4 clients
To see exactly what clients your server believes exist?

> Has anyone had problems with data loss/corruption?
No. But I've seen occasional random "soft" errors where
users can't access the server for a few seconds.
> Is the database used a Perforce creation?
I've heard it is based on Berkeley database from Sleepycat Software,
but the users and administrators don't need to be aware of this.
> Is there any way to run queries directly against the data?
Not that I know of. There is some fragmentary documentation
about the various tables, but it is not intended to be used much.
> How hard is the tool to administrate?
I've found that I only have to administer Perforce for adding and deleting
users.
Everything else seems to be automatic.
> How hard is it to train users on Perforce?
2 of our engineers attended the official Perforce training, and have been
supporting / training the rest of the other 30 users. It takes about an
hour or two for a new user to be up and running if they use the Windows GUI,
a day if they use the command-line interface.
> Are less technical users like graphics designers or

I don't know; they don't use it here.
> How well does Peforce work with remote users?
I've found it works fast and reliably, but is relatively tedious
to set up due to the syntax of the 'p4 protect' table.
There may be other ways of configuring Perforce with VPN
that would be easier.
> Any other good or bad things that I should consider?
Technical support is excellent, the best in the industry that I've experienced.
The company management appears to be very conservative.
This is neither good nor bad, just something to be aware of.

About 45 minutes. Our depot has about 150,000 files. We do the
checkpoint and tape backup with the server running.

About half the predicted size, or about 7 GB. That may be because
most of our users have mapped only part of the depot.

>users and 1000 files, but does the performance scale well?
Yes. If there are a lot of users trying to access the same
part of the depot they may see deadlocks that slow things down.
Users can minimize their exposure to this by limiting the
scope of their requests - each request sets a lock on part of
the database for a short time.

We haven't.

Pretty easy. Once you have automatic backups in place the
admin tasks amount to adding and removing users.

We give a half-day introduction, covering both p4 basics and
our practices. Most of our users pick it up on their own
from that starting point.
This includes documentation writers and managers.
The hard part is managing integrations, making sure changes
are properly merged into all code lines to which they apply.
>How well does Peforce work with remote users?
Pretty well. We have four sites, half a dozen always-remote
users, and many users who telecommute some days (as I'm doing
now). Perforce works fine as long as you have adequate bandwith.
When I was working over a 56 Kb modem I'd take a once-a-day hit
of 15 minutes or so to catch up with the code lines I was working
on. Doing the initial population of the code tree was tedious.
Remote users can choose to compress their communication with
the server.
>Any other good or bad things that I should consider?
We've always received friendly, competent, and prompt responses
from Perforce support people.
Give the server system plenty of RAM.
