Join David M. Franklyn for an in-depth discussion in this video Data storage and replication in a central site, part of Microsoft System Center Configuration Manager Essential Training.
- [Instructor] When you create a parent-child relationship in a Configuration Manager hierarchy, replication is configured automatically between the parent and child sites. Later, you can create routes manually if you want to customize the connection configuration. You can view the file-based connections in the file replication node under the hierarchy configuration folder in the administration workspace. For each parent-child relationship that you create, a corresponding file replication route is also created.
File-based replication used to communicate between site servers uses a file replication account to connect to the SMS_site chair on the destination server. Each file replication route can define a separate file replication account. When a site server is installed, the local group named SMS_site to site connection_xxx where those x's stand for your site code such as NA1 is created. The SMS_site to site connection_NA1 group for example is granted permission to the SMS_site chair and modify permission to the underlying folders.
When a new file replication route is created, the destination computer's Active Directory computer account is added to the SMS_site to site connection_xxx group. Now the SQL Server Service Broker port by default uses port 4022 and that's why in previous situations we opened up the firewall to allow that to be used. By default, compression is enabled for the SQL Server Broker port.
This setting applies to all of the data replication links. Data retention can be set between one and 14 days and is set to five days by default. If replication is interrupted for longer than the data retention period, the global data will be reinitialized on the parent site after replication is restored. By default, database replication takes place over not just port 4022 by the SQL Server Broker port, but also by SQL Server itself in port 1433.
These ports need to be open at firewalls before installing Configuration Manager sites to allow replication between the sites. And as we said before, this is all configured automatically when we install a new site. Now beginning with Configuration Manager 2012 Service Pack 1, a Configuration Manager administrator can configure some database replication settings. There are several configuration options for managing the database replication link. We have distributed views and you can configure this on the general tab of the parent site code to child site code replication link properties.
You can enable distributed views for any or all of the following, hardware and software inventory, software metering, and status messages. When you enable distributed views, the primary site doesn't replicate the selected information to the central administration site. By default, these settings are not enabled. Distributed views are only available for primary site to central administration site replication. The replication data summary option can be found on the general tab also of the parent site code to child site code replication link properties.
You can use the replication data summary settings to configure how often Configuration Manager summarizes reporting data for database replication traffic. By default, this interval is 15 minutes. You can schedule database replication on the schedule tab of the parent site code, child site code replication link properties. You can configure when replication will be available throughout the week. Additionally, you can control which data will replicate during these times either all site data or any of the following, hardware inventory, software inventory, software metering, and status messages.
