5250 commercial processing workload (5250 CPW) is the capacity to perform 5250 online transaction processing (5250 OLTP) tasks on i5/OS® logical partitions.
A 5250 OLTP task is a task that uses the 5250 data stream. Examples of 5250 OLTP tasks include the following:
On IBM System i5™ and eServer™ i5 models, the method used to determine the processing capability that is available for 5250 OLTP tasks depends on the edition type of the managed system. The following table shows how much processing capability is available for 5250 OLTP tasks.
| Edition type | Processing capability available for 5250 OLTP tasks |
|---|---|

100% of the processing capability of the managed system is available for 5250 OLTP tasks. However, the amount of processing capability that you are entitled to use for 5250 OLTP tasks is limited by the number of Enterprise Enablement features on the managed system. You cannot assign specific amounts of 5250 CPW to logical partitions. Each i5/OS logical partition can use up to its entire processing capability for 5250 OLTP tasks automatically, provided that the managed system does not exceed its entitlement. The number of Enterprise Enablement features on the system determines the number of processors that are available for 5250 OLTP tasks. A number of Enterprise Enablement features are included with each system. The number of Enterprise Enablement features included with the system depends on the server model and processor feature. If needed, you can purchase additional Enterprise Enablement features for the server. Alternately, you can purchase a Full Enterprise Enablement feature for some server models. This feature enables the entire processing capacity of all permanently activated processors for 5250 OLTP tasks. |

A fixed amount of the processing capability on the managed system is available for 5250 OLTP tasks. Percentages of this 5250 CPW can be assigned to i5/OS logical partitions. If you manage the system using an HMC, each i5/OS logical partition can use a fixed percentage of the total system 5250 CPW. When you use the HMC to activate an i5/OS logical partition, the HMC assigns this fixed percentage of system 5250 CPW to the i5/OS logical partition based on the 5250 CPW settings in the partition profile. After you activate the i5/OS logical partition, you can manually increase or decrease the percentage used by the i5/OS logical partition using dynamic logical partitioning. If you manage the system using the Virtual Partition Manager, all of the system 5250 CPW is assigned automatically to the single i5/OS logical partition. |
| Standard Editions | No processing capability of the managed system is available for 5250 OLTP tasks. However, you can use a single 5250 console session on each i5/OS logical partition. You cannot assign specific amounts of 5250 CPW to i5/OS logical partitions. |

On IBM System p5™ and eServer p5 models, 5250 CPW must be enabled using Enterprise Enablement features. You can enable up to the entire processing capacity available to the i5/OS logical partitions for 5250 OLTP tasks.
You can use the following tools to reduce the number of 5250 OLTP tasks that your managed system must perform:
