Managing Raft Replication

To run Raft replication operations on your Globally Distributed Database you must create a node where you can run GDSCTL commands.

More information about Raft replication operations can be found in the Oracle Database Globally Distributed Database Guide at Raft Replication Operations.

• Create a GDSCTL Node
  For many Raft replication life cycle management operations, you will need to create a node to run GDSCTL commands for Raft operations.
• Moving Replication Units
  You can move follower members of replication units from one shard to another.

Create a GDSCTL Node

For many Raft replication life cycle management operations, you will need to create a node to run GDSCTL commands for Raft operations.

1. Open the Actions menu in the Oracle Globally Distributed Exadata Database on Exascale Infrastructure details page, and select More actions, then Create Distributed Database CLI Shell.

2. Upload your public key for this node.

   If needed, you can generate keys in this panel.

3. If required, specify the subnet under Advanced Options.

4. Click Create.

Moving Replication Units

You can move follower members of replication units from one shard to another.

In the Shards tab or Replication details tab of the Globally Distributed Database details page, select Move Replication unit in the actions menu.

• Source shard: shard from which you want to move the replication unit follower.

• Destination shard: shard to which you want to move the replication unit follower.

• Replication unit: the replication unit numbers listed here identify which replication units have followers on the source shard that can be moved.
