As you select software for activating Capacity on Demand (CoD) resources, consider how you would like to license your software. Many methods are used to license software, such as per user, software tier, or per processor.
Typically a tool, such as a license manager, is used to manage the licenses. A license manager detects use of the software, compares it to the entitlement, and then takes action based on the results. A license manager can be provided by IBM or can be made available by the software provider.
This table shows Capacity on Demand software licensing considerations.
| Licensing Type * | Software type | Capacity Upgrade on Demand (permanent activations) | On/Off, Utility, and Trial CoD (temporary activations) |
|---|---|---|---|
| Per user licensing |
|
No Charge - User entitlement does not change when inactive processors are permanently activated | No Charge - User entitlement does not change when inactive processors are temporarily activated |
| Software tier licensing |
|
No Charge - Tier entitlement does not change when inactive processors are permanently activated | No Charge - Tier entitlement does not change when inactive processors are temporarily activated |
| Per processor licensing | IBM i, AIX®, Linux® | Per activation charge - One processor entitlement must be purchased for each permanently activated processor assigned to a partition that uses the software. | No Charge - Processor entitlement does not change
when inactive processors are temporarily activated. Note: This rule
might not apply to Linux,
see your Linux distributor
for details.
|
| Per processor licensing | IBM middleware | Per activation charge - One processor entitlement must be purchased for each permanently activated processor assigned to a partition that uses the software. | Daily user charge - One processor day of entitlement must be purchased each time that any number of inactive processors are temporarily activated. |
| *Note: It is possible that you use a combination of these licensing types. For details, consult the license agreement associated with your product. | |||
