Thanks Jim,

I had gotten to the following point (although you have now shown
me a better way to get there, I was using FileStorage):

<ZODB.DB.DB object at 0x137e910>
{'Application': < object at 0x1377d70>, '': <persistent.dict.PersistentDict object at 0x1377db0>}
< object at 0x1377d70>
<OOBTreeItems object at 0x1386228>

print f1[0].keys()[1]
        Rob's buddies
print f1[0].values()[1]
        <buddydemo.buddy.BuddyFolder object at 0x1377f30>
print f1[0].values()[1].__getitem__
<bound method BuddyFolder.__getitem__ of <buddydemo.buddy.BuddyFolder object at 0x1377f30>>

This is where I get stuck. Been going over the sources to figure out how to iterate over these.

You're 2nd point, about using ZEO, is also very valid (I need to just read my 'buddies' and send the data down to a bunch of embedded Linux based controllers but the ZODB will be locked).

I did notice since I did this, bin/runzope acts differently (on this Zope/ZODB?). I created a new instance in 121
and transferred all applications and the new instance works fine:

Robs-Laptop:~/Projects/Zope/Zope3/One2One rob$ cd ../121/
Robs-Laptop:~/Projects/Zope/Zope3/121 rob$ runzope
2006-10-27T14:45:57 INFO root -- HTTP:localhost:9090 Server started.
        Hostname: localhost
        Port: 9090
2006-10-27T14:45:57 INFO root Startup time: 9.072 sec real, 8.710 sec CPU

But the old instance in One2One now just seem to test:

Robs-Laptop:~/Projects/Zope/Zope3/121 rob$ cd ../One2One/
Robs-Laptop:~/Projects/Zope/Zope3/One2One rob$ runzope
2006-10-27T14:47:56 WARNING root Developer mode is enabled: this is a security risk and should NOT be enabled on production servers. Developer mode can be turned off in etc/zope.conf
Total: 0 tests, 0 failures, 0 errors
Robs-Laptop:~/Projects/Zope/Zope3/One2One rob$

Any idea what causes this?

Anyway, thanks again for your quick response!

I'm wondering if there is an easy way to get to persistent objects created in Zope and stored in ZODB

As an example, I would like to iterate over created 'buddies' in buddydemo.

The easiest way is to use zopectl, which takes care of opening the
database(s) and loading the Zope configuration for you.

Interactively, use "zopectl debug".  This will give
you an interactive interpreter with an "app" variable set to
the top-level folder.

Use "zopectl run <your_script>" to run a script with the
same "app" variable set and ready for use.

Of course you can use the lower-level ZODB APIs to open the database

Note that you'll want to use ZEO if you want to open the database while the
web application is running.
