How to Change Static and Dynamic parameters Oracle 19c

Question

I am working with Oracle 19c in Centos 7. After the installation, I want to Change Static and dynamic parameters of the newly created database.

After that, I need to read the alert log to witness the Changes.

Already I registered Pluggable Database(PDB) with a new Created Listener.

How can I change these parameters??

It's easier to use v$parameter and v$spparameter views:

select * from v$parameter;
select * from v$spparameter;

Description:

v$parameter

v$spparameter
