Modifying database replication from the user interface - BlueCat Integrity - 26.1.0

How to modify database replication once it has been configured.

1. Select the Settings tab in the sidebar.
2. Under Database management, select Replication settings.
3. Click Configure replication.
4. Under Configure replication, set the following database replication parameters:
   • Primary Server—displays the IP address of the Primary server.
   • Compression—displays whether compression is enabled for the database replication stream.
     Note: You can't enable or disable compression when updating database replication.
   • Latency warning threshold—enter a value to specify the warning threshold latency¹ of replication and set the Unit .

     When the latency between the Primary and Standby servers reaches the configured threshold, Address Manager logs a warning in syslog and sends an event to warn you that the database of the Standby server is behind the database of the Primary server by the configured threshold or greater. The default value is 1 hour.

     Note: If you set the value to 0 seconds, Address Manager will never send an event to warn you that the database of the Standby server is behind the database of the Primary server.
   • Latency critical threshold—enter a value to specify the critical threshold latency of replication and set the Unit. When the latency between the Primary and Standby servers reaches the configured threshold, Address Manager logs a warning in syslog and sends an event to warn you that the database of the Standby server is behind the database of the Primary server by the configured threshold or greater. The default value is 1 day.
   • Standby Server 1—displays the IP address of the first Standby server. Click Remove to remove the Standby server.
   • Standby Server 2—displays the IP address of the second Standby server if a second Standby server has been configured. Click Remove to remove the Standby server.
     Attention:

     • If you have two Standby servers in replication, you can only remove one Standby server. You must have at least one Standby server in replication.
     • If you are adding a second Standby server, the server can't be part of an existing database replication environment or a Removed Standby server. You can only add a Standby server if it's operating as a standalone server.

     Warning: If you are adding a second Standby server, the existing database on the new Standby server will be erased.
5. Click Configure.
6. If you have added or removed a Standby server, perform a full deployment to all managed DNS/DHCP Servers.
   Attention:

   • If you have removed a Standby server from replication, you can re-purpose the server as a standalone server. To re-purpose the server as a standalone server, you must reset replication on the Removed Standby server. For more information on resetting replication on Standby server, refer to Breaking and resetting database replication. Once a Removed Standby server has been reset to standalone operation, it can be added to a replication configuration again.
