it seams that the Product XRON does not work with python 2.2.
Perhaps you should be thankful .. We tried to use xron a year
or so ago, and it bit us repeatedly. We dropped it and use
cron to tickle a Zope URL or to call an external method. For
those, see:

I can create an instance, however when I try to enter into it from the zmi, I
get an error:
The object at http://localhost:8080/sprint/scheduler has an empty or missing
docstring.

Hi Steve,
I am running Zope under linux (Suse 6.4). And I would like to use
Xron. But, I can not get it running.
I did read your email : Xron on linux. And therefore I would like to
know, how you did manage to use Xron.

1. If you can use the management interface, you can disable a Xron Scheduled
Method by deleting it from the Schedule catalog or setting its reschedule
interval to null.
2. If you delete (or just rename __init__.py to something else in) the Xron
Product. And restart Zope, there will be no

Hi,
Could you please send your external python method. + Product for using in
combination with a cron job.
Because, this can really help me a lot.
Thanks,

This is a known problem. Search back thru the archives of [EMAIL PROTECTED] for
Xron and you will find some helpful information. I'll also try to find the

Yes, using Client.py was the easiest way to do that. The biggest problem
with Client.py is its dependency on HTTP. If your server is set up to
only accept HTTPS, then you can't use Xron -- not a desirable trade-off.
If security is the problem, you could configure the HTTP part to
listen only on

Xron has a single dispatcher thread. This thread knows how long to
sleep
for until the next job needs to run.
this model has problems when new jobs (for immeadiate execution) are
entered after the system sleeps. i think it should it
What if you want a small job to be done every 30 seconds?
I generally don't... I'm satisfied with cron granularity, although
others
might not be. Do you have this requirement?
I thought a little about the granularity issue and decided to go with
the most general solution. I have no
Steve,
I am also interested in scheduling... though I haven't looked closely at
Xron.
The Xron product seems rather "fragile" in use.
That is, if things go wrong when an Xron DTML Method is triggered, that
method doesn't get rescheduled.
Does Xron take an optimistic approach to repeating

I'll need to try to call get_transaction().commit() from a

I think it'll just work. I'll find out in a few minutes. :-)
Yes, it just works. :-)

Do you think this is this any more effective than having a producer
thread
do a lookup every minute to see what jobs are current, after which it
should
put the current jobs in a queue? E.g., as the "run" method of a
separate

I'd be glad to listen to well considered proposals for how Xron should
