Today I was trying to upgrade our CCM Call Manager Cluster from 3.3.2 to 3.3.3 version. Unfortunately following problem has occured.
When I was trying upgrade subscriber (after I install CCM 3.3.3 on publisher) I got following error message:
Failure occurred trying to get DBNAME value from registry. Aborting Cisco CallManager installation.
I suppose that I have made mistake rebooting publisher before upgrading subscriber. I have noticed in SQL enterprise manager that on publisher there is two databases : CCM300 and CCM301.
Only CCM301 is published
On subscriber there is only subscription of CCM300. Now I see that IP telephony system works but I can't proceed instalation on subscriber.
Has anybody had any experience regarding that problem ?
If you need more information I will provide it to you as soon as possible
Thanks in advance
