You may think: I know how to create and manage network configuration files. I simply run netca or netmgr and setup my needs. And what if they ask you to set this up using no GUI ?
So, doing it manually is not hard also. Personally, after many years of oracle experience I don't know by heart the syntax. So what do I do? I look up in the docs!
Even if you know the syntax, going to the docs, copying a template and adapting is much faster in my opinion.
So exercise:
- How to use netca.
- How to use netmgr.
- How to setup all things in sqlnet.ora / tnsnames.ora manually.
- There are some sqlnet.ora parameters that cannot be configured using GUI.
- There are also cman.ora and ldap.ora. I would recommend understanding them.
- How to get a quickly find in the Official Doc if you need it.
- How to change the network things via EM.
Path to Documentation:
Database Administration -> Net Services Reference
Database Administration -> Net Services Administrator's Guide (this one has an example link, very useful)

* Change ALL settings in netmgr and see how it affects the three major SQLNet files:
- sqlnet.ora
- tnsnames.ora
- listener.ora.
see what you CAN NOT enable/disable using the netmgr GUI. As Rodrigo suggested, go through the Reference doc, briefly get familiar with ALL parameters. You may need at least to know what they do.
* Practice setting up Load Balancing and Connect-time failover (you can setup basics in netmgr)

* Practice setting up TAF (you CAN NOT set this up in netmgr)

Hello Rodrigo,
netmgr can be run in silent mode? I have not found it on the internet... It has just GUI mode?
