You may also want to consider the availability of your applications. By
having all your apps on a single server and if the server is down, all your
apps will also be impacted. Unless, you have high availability built in at
the server level, i.e. cluster.

It is fine to have one web2py and as many domains as you need. It should
not affect performance provided you take advantage of the cores you have.
That means you want to make sure you use nginx+uwsgi or gevent or gunicorn

the idea is to separate it is base on the case

the same thing goes for account table that automatically create

do you really need separate tables, rather than a single table that simply

Thanks. I had already tried that, and it doesn't work for me. I wrote a

@auth.requires_login()

You can do:
otherSubject = request.post_vars.otherSubject or 'whatever'

FIELDSET('Other subject: ', INPUT(_name='otherSubject', value
= otherSubject)),

This is a nice solution, and clever, thanks!
The upside (compared to postgres locks, as discussed above) is this works

Here's a common scenario. I'm looking for the best implementation using the

I should explain why I posted that recommendation. The vision of using

Woohoo, this scheduler will *automatically handle locks*—so I don't need

In case it is useful to someone, here is the full code I used with locking,
using postgresql advisory locks. The benefit of using postgresql's locks
are that:
• It locks on the database—works across multiple clients
• The locks are automatically released if a client disconnects from the db
This scenario is working out worse and worse.

aren't any scheduler processes running behind them running! I'm guessing
