[Zope] Re: How to run periodic processes - How to set Mail Ho st

[sean.upton@uniontrib.com]

I like cron, but not in combination with wget.  I have found this (poking
methods via http) to be problematic for me in the past with automated tasks,
and have mostly switched over my processes to using out-of-process temporary
ZEO-enabled Zope.app() instances in python modules executed by cron jobs.

More info on my comparitive thoughts wget vs. Zope.app(), and example code:

I would also recommend you Cron. Once I used XCron and my system crashed
everytime without finishing the XCron Method (It wasn't a Xron issue, but it
affected
the XCron Schedule). When Zope tried to restart, it tried to excecute the
XCron
Method again, so I got another email. It did it till I opened my email box
(I got 500
emails).

With Cron and wget this won't happen because unix/linux finish the
excecution of the
method without caring if it whether crashes or not.

Josef
