I am getting a " Database Communication Error" whe I try to log into the CM administration and CM serviceability on the Publisher.
I have tried to restart the services by using the command "utils system restart". When I check the services running after the restart the following are not running:
A Cisco DB
A Cisco DB Replicator
Cisco CAR DB
Cisco CDR Agent
The system is configured in a cluster and the error appears on the Publisher. I am able to log into the Subscriber but sicnce it was configured for secondary/backup services only, I can not edit anything. Backup had not been done for a long time, so users are not able to work properly.
I can only access the Publisher through the CLI and restarting the stopped services has no effect.
There has been no IP address or hostname change on ether the Publisher or Subscriber. From the Subscriber, the Publisher is reachable (you can ping it from the Subscriber's OS administration).
LDAP synchronization between the Active Directory and Publisher was failing. We rebooted the Publisher with the aim of making the synchronization work. After the reboot, the "Database Communication Error" began.
No changes in IP or hostname have been made.
Ok, then please try solution 2 from below link
This is what I get when I run the test:
admin:utils diagnose test
Log file: platform/log/diag2.log
Starting diagnostic test(s)
test - disk_space : Passed (available: 30145 MB, used: 11677 MB)
skip - disk_files : This module must be run directly and off hours
test - service_manager : Passed
test - tomcat : Passed
test - tomcat_deadlocks : 0 second(s) left
Its not going beyond that.
what is the CUCM version u are using ?
in case if u are using CUCM 8.6(2) , u can build your publisher by restoring data from Sub.
Yes, looking at the output of "utils diagnose test" i would recommend opening a tac case as this may actually need TAC to require root access and work from there.
