Call Manager 4.0 and Database Helper read/write

[Luong Hoang Minh]

Hi,

I have question about CCM4 database on subcriber, please take a look at the attach file.

Question is: there are 02 subcriber, why 1 subcriber have write permision, 1 subcriber have no write.

As from some Cisco documents, subcriber only have read-only permission, and only publisher have write permission, so it make me confuse in this case.

Thank you for your help.

Hi Minh,

Your understanding seems to be right as per the CUCM 4.x Systems guide which says the following:

Both the SQL database and the LDAP directory run on every Cisco CallManager server within a cluster, and replication agreements automatically get set up between servers. The publisher server contains the master copy of both the SQL database and the LDAP directory, and it handles replication to all subscriber servers, which contain read-only copies of both repositories.

Hopefully someone still has 4.x cluster functional and can verify this behavior since TAC also does not support 4.x version now.
