On a Data Node, the Sync Data service synchronizes Address Manager information to the Distributed DDNS database. If the data node is shut down, the service is started on another data node in the cluster automatically.
Address Manager replication information with the Distributed DDNS database: If an Address Manager failover occurs and the IP address of the primary server changes, the service detects the change and updates configuration information to use the IP address of the new primary server.
Address Manager zone information with the Distributed DDNS database: When changes in zone information are detected, (such as DNS servers and TSIG keys), those changes are updated in the Distributed DDNS database. By default, the service checks for zone information changes every 30 seconds.
To use the Sync Data service, the BAM user under which the Distributed DDNS Application node logs into BAM must be an administrator user. The Distributed DDNS workflow needs these privileges to switch the connecting BAM to the new primary BAM. For more details, see Installing the Distributed DDNS Application Node on a BDDS.
To configure the Sync Data service:
-
If it's not already displayed, click the Database Nodes tab.
-
In the Manage DB Nodes table, in the Sync Data column, click the Settings gear icon for the row of the node you want to manage. This icon will be different colors (typically green) depending on the service status.
In the configuration window, enter the following information:
--- UPDATE_BAM_FAILOVER_INTERVALS: 60 UPDATE_TSIG_KEYS_INTERVALS: 30 UPDATE_ZONE_INTERVALS: 30
Where the parameters represent the following:
The interval at which the data node monitors the Address Manager replication status (in seconds). By default, the service checks Address Manager every 60 seconds (1 minute).UPDATE_BAM_FAILOVER_INTERVALS
The interval at which the data node monitors the Address Manager TSIG key information (in seconds). By default, the service checks Address Manager every 30 seconds.UPDATE_TSIG_KEYS_INTERVALS
The interval at which the data node monitors the Address Manager information (in seconds), such as whether the DNS Primary server for the zone is still primary and the TSIG key of the zone. By default, the service checks Address Manager every 30 seconds.UPDATE_ZONE_INTERVALS: 30
The interval at which the data node rereads resource records (RR) of the zones from the DNS Primary server. By default, the service checks resource records every 120 seconds.ZONE_TRANSFER_INTERVALS: 120
-
When you're done, click Save to save the Sync Data service configuration.
-
After the changes are saved, click Start to start the service and add it to the Distributed DDNS Service Node.
