Oracle Databaseのリスナーのポートの再構成、Net Configuration Assistantのsilent modeでは不可能？

You can run Net Configuration Assistant in silent mode to configure and start an Oracle Net Listener on the system, configure naming methods, and configure Oracle Net service names.

https://docs.oracle.com/en/database/oracle/oracle-database/19/ladbi/running-net-configuration-assistant-using-response-files.html#GUID-86CD4F09-BEF8-40B4-905C-5DA86582CD74

To run Net Configuration Assistant in silent mode, you must copy and edit a response file template. Oracle provides a response file template named netca.rsp in the $ORACLE_HOME/assistants/netca directory.

⇧ とあり、サイレントモードってもので実行すれば良いらしい。

ので、レスポンスファイルの中身を確認してみた。

sudo vi $ORACLE_HOME/assistants/netca/netca.rsp

$ORACLE_HOME/assistants/netca/netca.rspファイルの中身。

⇧ これのどの部分を変えればポート番号を変更できることになるのか、全く分からないんだが...

何故、netca.rspファイルをサイレントモードで実行してリスナーのポート番号を変更する手順をドキュメントに記載しないのか...安定の不親切、流石はOracleさん、というか悪意すら感じるのだが...。
