IBM z13s Technical Manual page 382

One major customer requirement is to eliminate the necessity for a customer authorization
connection to the IBM Resource Link system at the time of activation of any offering. This
requirement was first met by the zBC12 and is also available with z13s servers.
After the offerings have been installed on z13s servers, they can be activated at any time,
completely at the customer's discretion. No intervention by IBM or IBM personnel is
necessary. In addition, the activation of the CBU does not require a password.
z13s servers can have up to eight offerings installed at the same time, with the limitation that
only one of them can be an On/Off CoD offering. The others can be any combination of types.
The installed offerings can be activated fully or partially, and in any sequence and any
combination. The offerings can be controlled manually through command interfaces on the
HMC, or programmatically through a number of APIs, so that IBM applications, ISV programs,
or customer-written applications, can control the use of the offerings.
Resource consumption (and therefore financial exposure) can be controlled by using capacity
tokens in On/Off CoD offering records.
The CPM is an example of an application that uses the CoD APIs to provision On/Off CoD
capacity based on the requirements of the running workload. The CPM cannot control other
offerings.
