I think the 'share' calculation in DB12c Multitenant architecture's resource management looks new to many
seasoned Oracle DBAs.
shows that the total number of shares is seven (3+3+1). The
servicespdbPDB are each guaranteed 3/7th of the resources
But it really is not.
Shares are used
to define the relative importance of workloads in relation to other workloads.
This way of specifying resource has been used since at least Solaris 10.
I think there are other vendors' products which use this method.
