Defining zAAPs to the desired LPARs

zAAPs are configured via the normal PR/SM™ logical partition image profile. There are some requirements regarding zAAPs and standard CPs. The following requirements are associated with zAAPs:

• The number of zAAPs must not exceed the number of standard CPs for a server.
• You must have at least one standard CP defined for a partition. The z/OS® system needs at least one standard CP online at all times.
• You have the ability to set the number of zAAPs for an LPAR, although you cannot specify a weight or if the zAAPs are dedicated or shared. The zAAPs inherit the dedicated or shared attribute from the standard CPs in that LPAR.
• There is hard capping for zAAPs, but there is no support for soft capping (which is the WLM support for 4-hour rolling average). The existing single set of PR/SM logical partition processor weights (INITIAL, MIN, MAX) are applied independently to the shared standard CPs - capping only applies to shared standard CPs configured to the logical partition. If you use WLM weight management for the LPAR with SCRT, then z/OS WLM will manage shared standard CPs as today, but not the zAAPs.
• zAAPs will not participate in Intelligent Resource Director. The zAAPs will not participate in dynamic share management or in the number of logical zAAPs online.
