IBM i Application Server licensing

On an assigned logical partition on certain medium and large Power Systems models that have the IBM® i operating system, you can use an IBM i Application Server processor entitlement that allows minimal use of DB2® for IBM i.

On such a partition, you can run products such as WebSphere® Application Server or Lotus® Domino®, for example, that do not require DB2 for IBM i to run. The logical partitions with this option can also host applications that access DB2 data located in other systems or logical partitions.

The terms and conditions for an IBM i Application Server order are included in the License Information Document for IBM i. Ensure that you understand the terms and conditions for IBM i Application Server and keep this document in a secure location.

Processor entitlement keys on systems with IBM i Application Server

On systems that offer IBM i Application Server processor entitlements, the following types of processor entitlements are managed by one software license key (feature 5051).

5770-SS1 feature 5051: This processor entitlement key indicates the total number of IBM i processors across a system. You enter this 5051 processor entitlement key in each partition on the system. The value that you enter is compared to the 5051 key quantity to determine license compliance. The 5051 key quantity is the total quantity of IBM i processor entitlements plus IBM i Application Server processor entitlements.

5770-SS1 feature 5053: IBM i Application Server processor entitlement.

Consider these examples of how the processor entitlements are counted across the entire system.

If a system has two logical partitions with one 5051 processor in each logical partition, the system has a total of two 5051 processor entitlements.
If one of those logical partitions is assigned an entitlement for an IBM i Application Server processor, the system has two 5051 processor entitlements and one 5053 IBM i Application Server processor entitlement.
If one of the logical partitions has one processor and the other logical partition has two processors and a 5053 IBM i Application Server processor, the system requires three 5051 processor entitlements and two 5053 processor entitlements.
If one of the logical partitions has one processor with a 5053 IBM i Application Server processor enabled and the other logical partition has two processors and two 5053 IBM i Application Server processors enabled, the system requires three 5051 processor entitlements and three 5053 processor entitlements regardless of the version and release of the operating system.

Adding a 5053 software license key

If you used electronic software delivery to download feature 5053 online, the software license key for this entitlement is automatically added to your partition.

If you received a printed copy of your software license key for feature 5053, the steps for adding these keys are the same as for other software license keys. You can add the key to individual logical partitions or to all the partitions.

Adding support for IBM i Application Server

After you add a software license key for feature 5053 and you have an adequate number of activated processors, you can change the processor entitlements for a logical partition between one that has complete IBM i support and one that has IBM i Application Server support. To do this, you use the Set Application Server Support (QLZASPAS) API.

To add support for the IBM i Application Server, enter the following text on the command line:

CALL QSYS/QLZASPAS PARM('*ADD5053  ')

Removing support for IBM i Application Server

You also have the option to change a logical partition from being a IBM i Application Server partition to being a partition that has complete IBM i support.

To remove support for IBM i Application Server, enter the following text on the command line:

CALL QSYS/QLZASPAS PARM('*RMV5053  ')
