I am getting the error TNS-12537. In the SQLnet.ora file, if no IP Address is listed everything works fine and the listener starts without any issue. But one of the Security requirements we have is, we need to list all the client IP address on the SQLNet.ora file. I checked the Windows Firewall services and it is disabled.

Why are you using non-default listener (LISTENER_PRODITG)?

No listener.ora file is required to start or use Oracle listener.
move, remove, rename, delete or otherwise eliminate listener.ora file then do as below

lsnrctl start
lsnrctl status
# wait 60+ seconds below proceeding
lsnrctl service

COPY the results from above then PASTE all back here

Thank you for your reply.
I deleted the listener.ora from the path and now I am getting the same error TNS-12537.

these error are symptomatic of OS/Networking mis-configuration.

does hostname resolve to correct & valid IP#?

open Command Window & issue OS commands below

hostname
ping MCDBFOCUSPROD.global.corp
ping MCDBFOCUSPROD

COPY the results from above then PASTE all back here

Hmmm, above looks OK.
Are OS Services for both the listener & the database started & running now?

You must execute this on MCDBFOCUSPROD.global.corp and with ORACLE_HOME and PATH set for with the listener home.
