How to launch Connector with multi worker?
I used guide available for Multiprocessing in openerp-connector.
I created a bash file as start_connector and it contains
#!/bin/bash
PYTHONPATH=/opt/openerp/v7.0/server connector/openerp-connector-worker --config /etc/openerp-server.conf --workers=2 --logfile=/tmp/openerp-connector.log
and I tried to start this file using this command
$ ./start_connector

ValueError: Attempted relative import beyond toplevel package
Where am I wrong?
or Is there a better method of launching in multi-worker mode for connector?
PYTHON RELATIVE IMPORT ERROR (Google PEP328).
This mean that the file exception.py can't be found.
NB: Try first to check if your addons custom-modules (/opt/openerp/v7.0/custom_modules/launchpad/openerp-connector) is in the addon_path of your openerp-server.conf, add it if not.
This error is due to your installation path !
You can edit your .....opt/openerp/v7.0/custom_modules/launchpad/openerp-connector/connector/queue/job.py file at line 34:
and give the right path to the file exception.py: from the-full-path-to-the-connector-module.connector.exception import ............
Like in: from openerp.addons.connector.exception import .........
This also can be corrected in /queue/__init__.py by importing the /connector/exception.py package
The BEST WAY to avoid this kind of errors is to use an ABSOLUTE IMPORT
Use this buildout configuration that provide a helper script to run the multiprocess workers.
When I looked into the community mailing list, there were 2 messages that had similar topic of Multi worker Support
1. https://lists.launchpad.net/openerp-connector-community/msg00320.html
2. https://lists.launchpad.net/openerp-connector-community/msg00005.html
But there seems to be no other useful leads to solve this problem.
Need assistance.
You can try Magento openerp connector provide by webkul : https://store.webkul.com/Magento-Extensions/Magento-OpenERP-Bridge.html
Their code don't base on worker concept but using core observer pattern of mangeto

Did you manually edited the connector files? Because the line "from connection.exception import (NotReadableJobError," is normally "..exception import (NotReadableJobError,"
@Guewen Baconnier: yes, I made changes to solve the error. I have updated the original error.
