TNS-01151: Missing listener name, APPS_PROD, in LISTENER.ORA

Looks like that installation did not complete successfully.
There are files missing e.g. listener.ora

You have two options.
1) Try reinstalling Oracle first. If you are getting the same error then
perhaps the issue could be attributed to missing Linux packages then
You can reinstall linux and then Oracle.
2) You reinstall Linux and then Oracle.

In order to restart Oracle installation simply remove PROD folder from Oracle home.

rm -r PROD

Issue this command from Oracle home.

You can then restart the installation.
