Managing replication

To help manage the load on an HCP system and the replication network, you can control the performance level for send activity on each replication link in which the system participates. You can use a schedule to change the performance level for a link automatically at specific times on a weekly basis. Alternatively, you can choose a single performance level for the entire week.

Occasionally, you may need to temporarily stop all send activity on an individual link. Or, you may want to temporarily stop send activity only for particular tenants.

Rarely, you may need to stop all activity on all links in which the HCP system participates. This action stops not only replication and recovery but also read and repair from remote systems. It also prevents you from changing which items are included on the links.

If the HCP system uses virtual networking, you can select the network to use for communications through any replication link. You typically do this only once.

You can control whether the HCP system allows DNS failover to other systems in the replication topology. Disallowing DNS failover prevents the system from servicing requests redirected from remote systems regardless of whether this is allowed by the targeted namespace.

You can configure an HCP system to automatically share its domains and SSL server certificates with other systems with which it participates in replication links. This ensures that SSL works for access to replicated namespaces on those systems.

You can manage the load the Replication Verification service puts on the system by disabling the service, setting the service to run once, or allowing the service to run continuously.

This section of the Help explains how to perform the tasks outlined above.

To view replication link schedules and global replication settings, you need the monitor role. To modify replication link schedules, manage replication at the link, tenant, and system levels, and set global replication options, you need the administrator role.

NoteYou can also use the HCP management API to manage replication.
