Oracle GoldenGate Marketplace: How to change user to root
I created a VM from Oracle GoldenGate Marketplace (for migration purpose). As with any compute instance, when I connect to it, it connects me as opc user. But from there, I cannot switch to the root user. I need to perform some changes on the /etc/hosts file and I couldn't do that. The following command fails:
sudo su -
It returns an error that the user is not enabled.
Any idea on how to resolve the issue please?
