Hi All,
I'm new to this product, I just hired as maintenance engineer for oracle products, and first thing I need to is listing the product and crosscheck it with the welcome letter. So i have been trying to looking document or discussion about how to check or determine installed product in Linux server, which mostly are referring to use of rpm -qa/dpkg -l or cat /etc/oratab, when I tried to use those command, it wouldn't let me know to which oracle products are installed. So do you have any suggestion on how to do it ?
I just need to fill which the colored column like in picture below

Thank you
Regards,
Faizal Hasymi
