An administrator needs to patch Oracle DB engines, but the Update button is not present in the database server VMs. What could explain the current…

In Nutanix Database Service (NDB), patching Oracle database engines requires the "Update" button

to be available on the database server VM’s management interface. If this button is missing, it

typically indicates a configuration issue preventing NDB from performing the patching operation. The

most common and critical reason is that the operating system (OS) credentials for the database

server VM have not been set or registered with NDB. These credentials are necessary for NDB to

authenticate and execute patching tasks on the VM, such as accessing the Oracle software and

applying updates via a software profile.

Option A is correct because missing OS credentials prevent NDB from establishing the required

connection to the VM, disabling the Update button.

Option B (Database parameters are missing) is incorrect because while database parameters are

important for configuration, they do not directly control the visibility of the Update button for

patching.

Option C (Oracle DB engines cannot be patched) is incorrect as NDB explicitly supports patching

Oracle databases when properly configured.

Option D (Software profile is not published) is incorrect because an unpublished software profile

might limit availability to users, but the Update button’s presence relies on VM connectivity, not

profile publication status.

To resolve this, the administrator must register valid OS credentials for the VM in NDB, enabling the

patching functionality.
