noteThe header of my working notes calls this listener opdb (TCP:1525). The name typed into NETCA was CLSDB. The port is the same in both places.

The answers given to the Oracle Net Configuration Assistant (netca) to add one more listener to the cluster, named CLSDB, on TCP port 1525, for the database that is created afterwards.

Item	Value
Tool	`netca`
Started on	`oradb01`, as `oracle`, with an X server running on the workstation
Listener name	`CLSDB`
Protocol and port	TCP 1525
Software version at the time	Oracle Database 11.2.0.4

The answers

ini

# Screen / Field = value, in the order of the assistant's screens.

Select the type of Oracle Net Services configuration / Cluster configuration = checked

Choose the configuration you would like to do / Listener configuration = checked

Select what you want to do / Add = checked

Listener name / Listener name = CLSDB

Selected Protocols / Selected Protocols = TCP

TCP port selection / Use another port number = 1525

Would you like to configure another listener? / No = checked

Answer	What it means
Cluster configuration	The listener is configured for the cluster and not for the local node only. The notes show no screen on which nodes were selected
Use another port number = 1525	The notes give no reason for 1525; 1521 is the SCAN port given to the Grid Infrastructure installer

The notes hold neither the resulting listener.ora nor any srvctl or lsnrctl output for this listener, so the file NETCA wrote and the state of the listener afterwards cannot be shown.

Checked against Oracle AI Database 26ai

As built	Today
`netca` in graphical mode	NETCA still exists and also runs in silent mode with a response file (`netca.rsp`)
Clustered listener added through the assistant	`srvctl add listener` is the documented command-line way to add a listener to a cluster

Nothing in this answer set is desupported. A response file or the srvctl command would have left something to show here in place of a list of clicks.
