Question is on setting of Physical and Virtual processors for LPARs to make proper use of virtualization capabilities.

Environment is a 8-way p570 with 4 LPARs.

lparVIO1 and lparVIO2:
AIX 5300-04-01
Mode/Type= Shared-SMT/Capped
Minimum Processors= 0.10
Desired Processors= 0.50
Maximum Processors= 1.00
Minimum Virtual Processors= 1
Desired Vritual Processors= 2
Maximum Vritual Processors= 4

lparORA:
AIX 5300-04-CSP
Mode/Type= Shared-SMT/Capped
Minimum Processors= 2.00
Desired Processors= 4.00
Maximum Processors= 8.00
Minimum Virtual Processors= 4
Desired Vritual Processors= 4
Maximum Vritual Processors= 64

lparDB2:
AIX 5300-05-03
Mode/Type= Shared-SMT/Capped
Minimum Processors= 3.00
Desired Processors= 3.00
Maximum Processors= 8.00
Minimum Virtual Processors= 3
Desired Vritual Processors= 3
Maximum Vritual Processors= 64

The lparORA only really needs 4 processors during a 1am to 5am (monday-friday) window for some batch jobs which are cpu intensive. At all other times the lparORA at most uses only 50% of it's current entitled capacity of 4.00. So the question is how to set the lpar processors allocations to let the lparORA use up to 4 processors during the 1am to 5am window
but let the lparDB2 use up to 6 processors. The numbers of 4 and 6 are driven by the licensing of Oracle (4 dual-core processors) and DB2 (6 dual-core processors)..

Does the following then make sense (changing all to Uncapped and adjusting the processors settings):
lparVIO1 and lparVIO2:
AIX 5300-04-01
Mode/Type= Shared-SMT/Uncapped
Minimum Processors= 0.10
Desired Processors= 0.50
Maximum Processors= 1.00
Minimum Virtual Processors= 1
Desired Vritual Processors= 2
Maximum Vritual Processors= 4

lparORA:
AIX 5300-04-CSP
Mode/Type= Shared-SMT/Uncapped
Minimum Processors= 2.00
Desired Processors= 2.00
Maximum Processors= 4.00
Minimum Virtual Processors= 4
Desired Vritual Processors= 4
Maximum Vritual Processors= 4

lparDB2:
AIX 5300-05-03
Mode/Type= Shared-SMT/Uncapped
Minimum Processors= 2.00
Desired Processors= 2.00
Maximum Processors= 6.00
Minimum Virtual Processors= 6
Desired Vritual Processors= 6
Maximum Vritual Processors= 6

Any thoughts or suggestions would be appreciated.

If you want lparORA to have priority over lparDB2 you need to make lparORA have more weight than lparDB2. That should do the trick.
