Issue
I am working with Oracle 19c in Centos. After Oracle installation, not available tnsnames.ora file.but the listener.ora file is available
Solution
It should reside in your oracle_home\network\admin directory.
If not, create one yourself. Download sample file (from e.g. here) and adjust it so that it reflects your environment.
