Method open-controller (in bdb-controller.lisp) is not getting the register
parameter I'm specifying. I'm investigating why.

I should try :recover nil :register t -- doing that now.

Tried with an empty store and :register flag set to T. I get the same error.
Hmm...

I've set the ':register t' but that does not seem to have an effect. I am
now going to try with a completely empty store directory to see if that
makes a difference (maybe new elephant didn't like old data).

Hi folks,
I have two processes accessing the same BDB. One process manages weblocks
requests on port 80, the other on port 443. In the elephant from last
January, I was able to start, connect and use BDB from both processes. Now,
when I the user is redirected to port 443 and the process tries to
To fix this, I run
(elephant:find-inverted-index 'product-set 'rank)
But I still don't understand how this could have happened. My guess is that
it may have to do with adding the 'rank slot recently has confused the index
somehow. I don't know how.

I have a strange situation. I get inconsistent results when using
get-instances-by-class and map-inverted-index. The first one is correct,
the second one returns a bunch of NILs in the list in addition to the
correct results. Is this a bug or an expected result? Here are my commands
and output:
Given the OID, Is there a way to obtain an object slot value without
recreating the object? I want to reacreate the object only when a specific
value is present.
I am aware that I could use map-inverse-index to search for value, but it
does not do exacty what I want: I want to get all the object

I have a dilemma deciding on the structure on persiting data. I need your
advice on.
I'm relying on a third party package (Amazon-ECS) that helps me parse Amazon
XML data feed, with the result that the XML is translated into a set of
nested CLOS objects (all classes use metaclass ELEMENT-CLASS).
In an evolving site there is a fair chance of adding/changing/deleting slots
from a class. What are good practices with respect to these actions in
Elephant? Are there specific steps that need to be taken to migrate data
from an old class definition to a new class definition? Any gotchas one

I've run into several situations where I want to query for objects that
match values two or more slots. I currently do something like this:
(defclass my-class ()
((a :accessor slot-a)
(b :accessor slot-b
:index b))
(:documentation "my test class"))

Ian,
I think the later is what's supported/implemented by BDB:
"Berkeley DB supports replication over multiple systems, enabling
applications to scale massively with low latency and provide fault tolerance
for high availability solutions. This technique works by having all updates
go to a designa
Great! Thanks for sharing this info.

Could someone point me to any discussions WRT to choice of back-end? I'm
looking at BDB and Postmodern. What are advantages/disadvantages of either
one?
I'm guessing that Postmodern offers an opportunity of using and SQL querying
against PostgreSQL backend for out-of-process querying and such (

I have two classes, one an "ephemeral" and one persistent. The persistent
class inherits from the ephemeral class. When I copy slot values from an
ephemeral instance to persistent instance, only the slots that are redefined
in the persistent class get persisted properly, the other inherited slot

I'm trying to access BDB 4.5 backed elephant store (elephant-unstable) from
two different lisp processes using the elephant package. Is this a safe

I'm guessing it is not... as that's what's causing some of my data
problems I thought BDBs can handle multi-process access.

I've converted my weblocks app to use elephant. One of the first things I
do is to initialize some variables. One of the variables is a "demo" item,
that I use as a placeholder until the user choses something more specific.
I'm having trouble initializing the dummy. Here is my code:
