Manage Peer Nodes

This topic contains information about peer nodes, including how to view and edit peer nodes and how to get a list of chaincodes that are installed on a peer.

View and Edit the Peer Node Configuration

A peer 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 Peer Node Attributes.

1. Go to the console and select the Nodes tab.
2. In the Nodes tab, go to the Nodes table, locate the peer node that you want configuration information for, and click the node’s More Actions button.
3. 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.
4. If you're an administrator, then modify the node’s settings as needed.
5. Click Submit to save the configuration changes, or click X to close the Configure dialog.
6. Restart the node to apply any changes that you made.

List Chaincodes Installed on a Peer Node

You can view a list of the chaincodes and their versions installed on a specific peer node in your network.

If you don’t see the chaincode or the chaincode version you were expecting, then you can install a chaincode or upgrade a chaincode to the peer node. You must be an administrator to install or upgrade a chaincode.

1. Go to the console and select the Nodes tab.
2. In the Nodes tab, click the name of the peer node you want to see information for.
   The Node Information page is displayed.
3. Click the Chaincodes pane to view a list of chaincodes installed on the selected peer node.
