hi
Little bit elaborated:
NODE_DISCOVERY_ADDRESS
The master repository located on the deployment manager installation contains the serverindex.xml file for each node. The deployment manager reads this file on startup to determine the host name and IP port of each node
agent’s NODE_DISCOVERY_ADDRESS.
The default port for the NODE_DISCOVERY_ADDRESS is 7272. You can verify this by looking at the NODE_AGENT stanza in the serverindex.xml file of each node located at:
/config/cells//nodes//serverindex.xml
CELL_DISCOVERY_ADDRESS
The copy of the configuration repository located on each node contains the serverindex.xml file for the deployment manager. The node agent reads this file on startup to determine the host name and IP port of the deployment manager’s CELL_DISCOVERY_ADDRESS.
The default port for the CELL_DISCOVERY_ADDRESS is port 7277. You can verify this by looking at the DEPLOYMENT_MANAGER stanza in the serverindex.xml file for the deployment manager node located at:
/config/cells//nodes//serverindex.xml
cheers.
