I must thank my fellow DBA Franky Weber Faust for his publication in his blog.
We know NetCA Oracle command line for configuring the Oracle listener. NetCA stands for (Network Configuration Assistant). NetCA is used as a configuration assistant launched by the OUI at install time. It is more suitable for a batch mode for silent installations.
I will show how to create the Listener with NETCA in text mode using a response file. Before creating the database I like to create the Listener because if we are going to configure the Enterprise Manager the Listener must be previously created and running.
Listener creation process using NETCA via response file
Adjust the environment variables:
[oracle@oracle-srv netca]$ . oraenv ORACLE_SID = [cdb] ? cdb2 ORACLE_HOME = [/home/oracle] ? /u01/app/oracle/product/18.104.22.168/db_1 The Oracle base remains unchanged with value /u01/app/oracle
Run NETCA by passing the response file. The response file default that comes with the installation is enough to upload a Listener, if necessary you can adjust it as you want.
[oracle@oracle-srv netca]$ netca -silent -responsefile /u01/app/oracle/product/22.214.171.124/db_1/assistants/netca/netca.rsp Parsing command line arguments: Parameter "silent" = true Parameter "responsefile" = /u01/app/oracle/product/126.96.36.199/db_1/assistants/netca/netca.rsp Done parsing command line arguments. Oracle Net Services Configuration: Profile configuration complete. Oracle Net Listener Startup: Running Listener Control: /u01/app/oracle/product/188.8.131.52/db_1/bin/lsnrctl start LISTENER Listener Control complete. Listener started successfully. Listener configuration complete. Oracle Net Services configuration successful. The exit code is 0
Verify that the Listener is running:
