[Zope] Limit transaction undo

[Charlie Reiman]

The answer to mostly of your questions is yes.

Automated packing of the database is pretty easy with wget and cron. Capture
the URL that gets sent when you click on pack, then put that in a wget cron
job with the appropriate authentication. This is left as an exercise for the
reader (although someone will probably give you a crib sheet before you even
read this message).

Undo can be removed by changing ZODB to use a different backing store. See,
for example:

http://www.zope.org/Products/OracleStorage
http://www.zope.org/Members/tsarna/BerkeleyStorage

There might be others.

As for learning about transactions: I'm not sure. Try the developer docs or
look for ZODB docs.
