Backgroundrb devel - Mar 2009 - Issue starting backgroundrb server (with Oracle)

Hello All,

I?ve recently started trying to use backgroundrb and I?m running into an
issue with starting the server.  I?m running OSX (leopard) and rails 2.0.2
with an oracle database.
When I run ./script/backgroundrb start I get the following error:
/Library/Ruby/Gems/1.8/gems/activerecord-2.0.2/lib/active_record/connection_
adapters/abstract_adapter.rb:150:in `log'': OCIError: ORA-02014: cannot
select FOR UPDATE from view with DISTINCT, GROUP BY, etc.: select * from
(select raw_sql_.*, rownum raw_rnum_ from (SELECT * FROM
event_tracking.bdrb_job_queues   WHERE ( worker_name
''upload_invitees_worker'' AND taken = 0 AND scheduled_at <=
''2009-03-19
13:38:04'' ) ) raw_sql_ where rownum <= 1) where raw_rnum_ > 0 FOR
UPDATE
(ActiveRecord::StatementInvalid)

I?ve read in a few places that when using Oracle it may be a good idea to
remove the lines that say allow_concurrency = true, and I?ve done that.

Also, I saw that there may be an issue with oracle adapter with a SELECT ...
FOR UPDATE statement locking rows here:

The comment points to this occurring with backgroundrb.

I would appreciate any help that you all can provide.

Thanks,
Matt Stone
