Dans un cluster Cisco CUCM composé d’un publisher et de plusieurs subscribers, il arrive que la base de donnée répartie ne soit plus bien synchronisée entre les membres.
Il est critique de réaliser ce diagnostic au plus tôt : la procédure ci-dessous explique comment le réaliser.
Il faut tout d’abord se connecter sur le Publisher (dans notre cas c’est un serveur en version 8.0.3) en SSH et taper la commande utils dbreplication status
admin:utils dbreplication status
-------------------- utils dbreplication status --------------------
Replication status check is now running in background.
Use command 'utils dbreplication runtimestate' to check its progress
The final output will be in file cm/trace/dbl/sdi/ReplicationStatus.2012_01_19_08_31_26.out
Please use "file view activelog cm/trace/dbl/sdi/ReplicationStatus.2012_01_19_08_31_26.out " command to see the output

La vérification du bon statut de réplication prend du temps : le fichier de résultat ne doit pas être visionné immédiatement. Pour évaluer la progression de ce diagnostic, il faut utiliser la commande utils dbreplication runtimestate
admin:utils dbreplication runtimestate

la ligne en gras « Replication status command in PROGRESS 421 tables checked out of 519 » permet de connaitre l’avancement.
La colonne « Replication Loop » peut contenir 3 valeurs :
- 1 : initializing
- 2 : ok
