OS: Oracle Linux 7.7
GI/RDBMS version : 19c
I have only worked in 11.2.0.4 GI. So, my team and I never had to install MGMTDB repository DB in our shop.
Now, I need to build a 3-node production RAC DB.
As I understand, Grid Infrastructure Management Repository (GIMR) is not mandatory to install in 19C.
So, is it worth installing in 19C ?
