This question has nothing to do with Oracle RDBMS, but with Oracle Linux OS and the OS user oracle.
Please use the correct forum.
And apparently it was not created, so you need to create it manually.

If you read the installation docs for whatever version of the database you are installing, it should tell you the exact steps necessary to create the Oracle user. What gave you the idea it was created by default? There are some pre-created images for virtuals?
yes your understanding is correct oracle user is there in OEL by default.
first check oracle user exist or not
$ grep oracel /etc/passwd then or
$ ls -lrth /home/oracle
as root user run this command (change password for oracle user)
$ passwd oracle
then u will b able to use oracle account.
Thank you everyone. I created a new user without a problem. Moving on...
