Created by: Roland Russwurm on 03-02-2011 12:15:01 PM Hi, I'm wondering if it is possible/recommended to also start and access the AXL service on a subscriber. I remember that I read somewhere a message telling me it is not recommended because AXL is used to update the database which is only possibly on the publisher. Is this also valid if we strictly do only read access to query the CUCM DB without any updates? It would help us a lot for improved availability of our application and I think it could also be good for CUCM performance if we would load balance read requests to different servers. I have not found any best practices for this so I would be happy for any feedback. Regards, Roland

Subject: RE: Re: New Message from Roland Russwurm in Administration XML (AXL) - Admi Replied by: Stefan Slominski on 04-02-2011 06:43:57 AM running on CUCM version 8.0.3 you can access subs via AXL and send write-commands (tested with CFA). works with pub running and with pub offline. I don't know for sure but i think this is available since version 7 of CUCM
Subject: RE: AXL service on subscriber for readonly backup/load sharing Replied by: Roland Russwurm on 11-02-2011 08:30:29 AM Thanks for the response but actually I am happy with read only requests.
In my opinion write requests are always redirected to the publisher (even if accepted by the AXL interface on the subscriber) so it does not give you performance or availability advantages.
