Datastore Control Center
The database master is the main database. All data is written to this database, with the other database
synchronizing with it. If the database master fails, then data can be written to the database on the second
node. When the database master is back online, it returns to accepting writes. It also synchronizes with
the other database to ensure data consistency is maintained in the cluster.

Network Outage
By default, replication between two nodes is removed if they are not able to synchronize with each other
due to network outage for a substantial period of time. If the replication is dropped due to network
outage, an alert is sent to the administrator so that the administrator can take corrective action.

Note
Even though the replication between the nodes is removed, data could still be written to the database,
which is accessible to the Unified CCX engine.

If the replication is removed, the administrator can go to Tools > Datastore Control Center >
Replication Servers submenu from the Cisco Unified CCX Serviceability menu bar and click Reset
Replication. This ensures that the replication is established between the nodes and the data
synchronization (repair) process is initiated. Click Check Details icon in this web page to monitor the
status of the repair.

If the network outage did not result in the replication setup being removed, once the network is up, the
synchronization of data between the databases will happen automatically. For outages that last a few
seconds, typically the administrator need not take any action and the system will be able to synchronize
automatically.

Datastore Control Center
Unified CCX Cluster configuration is not complete until Agent, Historical, and Repository publishers
are configured. The Datastore Control Center in Unified CCX 8.0(1) displays the status of datastore
replication, allows you to synchronize data, and reset replication functions.

Note
Support for High Availability is available only in multiple-server deployments.
Use the Datastore Control Center to perform the following functions:
•
Obtain an overview of the datastores in the cluster and their relationships.
•
Manage the datastore read/write access.
•
Monitor and control the replication state (available only for Agent, Historical, and Repository
datastores.)

Tip
The Datastore Control Center page is available even in single-node deployments but you can only
monitor the read and write access. You cannot synchronize data, reset replication, or control the
replication state.
