Creation of Listener via NETCA in text mode

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/12.2.0.1/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/12.2.0.1/db_1/assistants/netca/netca.rsp
Parsing command line arguments:
Parameter "silent" = true
Parameter "responsefile" = /u01/app/oracle/product/12.2.0.1/db_1/assistants/netca/netca.rsp
Done parsing command line arguments.
