The Sync Data service manages the service that 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. The following information in
synchronized:
- Synchronizes Address Manager replication information to 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. By default, the service checks for changes every minutes.
- Synchronizes the Address Manager zone information, such as DNS servers and TSIG keys, to the Distributed DDNS database. By default, the service checks for changes every 30 seconds.
- Click the Settings icon under the Sync Data column.
- In the configuration window, enter the following
information:
--- UPDATE_BAM_FAILOVER_INTERVALS: 240 UPDATE_TSIG_KEYS_INTERVALS: 30 UPDATE_ZONE_INTERVALS: 30
Where the parameters represent the following:- UPDATE_BAM_FAILOVER_INTERVALS: The interval at which the data node monitors the Address Manager replication status (in seconds). By default, the service checks Address Manager every 240 seconds (4 minutes).
- UPDATE_TSIG_KEYS_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_ZONE_INTERVALS: 30: The interval at which the data node monitors the Address Manager zone information (in seconds). By default, the service checks Address Manager every 30 seconds.
- Click Start to enable the Distributed DDNS service.
- Click Save to save the Distributed DDNS service configuration and add the service to the Distributed DDNS Data Node.
