– Minimum processing weight
– Maximum processing weight
– WorkLoad Manager enablement

– Global enablement of event-driven dispatching
– Defined capacity
v
Using the Change Logical Partition Input/Output (I/O) Priority Queuing Controls
task, you can change the following LP definitions:
– Minimum input/output (I/O) priority
– Maximum input/output (I/O) priority
v Using the Change Logical Partition Security task, you can change the following
LP definitions:
– Global performance data control
– Input/Output configuration control
– Cross partition authority
– Logical partition isolation
Changes Available at the Next LP Activation
The following changes are available at the next LP activation:
v Use the IOCP RESOURCE statement to specify the MIF image ID numbers
assigned to the LPs. The only way to change the specified MIF image ID
numbers is by creating a new IOCDS.
v
Use the Partitions page in the reset profile to change the:
– LP automatic activation order
v Use the General page in the image profile to change the:
– Logical partition identifier
– Mode of the LP
– Enablement of the Logical partition time offset
v
Use the Processor page in the image profile to change the:
– Number of CPs, ICFs, IFLs, IFAs, or zIIPs
– Whether or not CPs are dedicated to an LP
– Weight capping
– WorkLoad Manager enablement
– Initial processing weight
– Initial capping enablement
– Minimum processing weight
– Maximum processing weight
v
Use the Options page in the image profile to change the:
– Minimum input/output (I/O) priority
– Maximum input/output (I/O) priority
– Defined capacity
v
Use the Security page in the image profile to change the:
– Global performance data control
– Input/output configuration control
– Cross partition authority
– Logical partition isolation
v Use the Storage page in the image profile to change the:
– Central storage definitions
– Expanded storage definitions
v
Use the Time Offset page in the image profile to change the:
– Logical partition time offset
v
Use the Load page in the image or load profile to change the:
