kamctlrc controls Kamctl that is an outside script that one can decide to use to manage Kamailio. It has it’s own set of database connection methods and can’t use the cluster module in Kamailio. There are two cases where kamctl and kamdbctl (the sister script) use database - to create the actual database and to search/update. With a master/master you decide if you create the tables on one side and let mysql replicate or if you create it on both sides before you initialize replication. For other queries you can choose to simply refer to one of the servers in kamctlrc - it’s usually not mission critical. If that server is down, your query will fail but the Kamailio service will run thanks to cluster logic in the db_cluster module. If you want a similar functionality for kamctl you may want to install the mysql proxy that can do failover in a way similar to db_cluster. Cheers, /O
