Manage Orderer Nodes

This topic contains information about ordering service nodes (OSNs), including how to view and edit OSNs, how to view the health information for an OSN, and how to add an additional OSN.

View and Edit the Orderer Node Configuration

An orderer node’s configuration determines how the node performs and behaves on the network.

Only administrators can change a node’s configuration. If you've got user permissions, then you can view a node’s configuration settings. See Orderer Node Attributes.

Go to the console and select the Nodes tab.
In the Nodes tab, go to the Nodes table, locate the orderer node that you want configuration information for, and click the node’s More Actions button.
The configuration option is determined by your permissions. If you're an administrator, locate and click Edit Configuration. If you're a user, locate and click View.
The Configure dialog is displayed.
If you're an administrator, then modify the node’s settings as needed.
Click Submit to save the configuration changes, or click X to close the Configure dialog.
Restart the node to apply any changes that you made.

Add an Orderer Node

Founder instances are provisioned with 3 OSNs, all of which are active after instance creation. Additional OSNs can be scaled out as described in Scale Your Instance. These OSNs will not be started automatically. You must start them and export the updated network configuration block to the partipant instances as described in Join the Participant or Scaled-Out OSNs to the Founder's Ordering Service.

Participant instances are created with 3 OSNs, but none of these OSNs are joined to the network or started when the instance is provisioned. You must follow the instructions in Join the Participant or Scaled-Out OSNs to the Founder's Ordering Service in order to join them to the network and start the nodes. If you want to scale out the participant OSNs these steps must be repeated.
