Example 12-23 Example of Showing CPUs Assigned to Defined CPU Pools on
Oracle Database Appliance Virtualized Platform Nodes
This oakcli show cpupool example shows the CPUs assigned to each defined
CPU pool on Node 0:
oakcli show cpupool -node 0
Changing the Number of CPUs Assigned to a CPU Pool on Oracle
Database Appliance Virtualized Platform Nodes
Use the oakcli configure cpupool command to change the number of CPUs
assigned to a CPU pool.
An Oracle VM Server can belong to only one virtual pool. However, you can change
the resources allocated to a virtual pool to increase the CPU resources available to the
virtual machine.
Example 12-24 Example of Changing the Number of CPUs Assigned to a CPU
Pool on Oracle Database Appliance Virtualized Platform Nodes
This oakcli configure cpupool example changes the number of CPUs assigned
to the CPU pool named
linpool
on Node 1. After the command runs, the new number
of CPU resources assigned to the CPU are six.
oakcli configure cpupool linpool -numcpu 6 -node 1
Assigning a Virtual Machine to a CPU Pool on Oracle Database
Appliance Virtualized Platform
Use the command oakcli configure vm to assign a virtual machine to a CPU
pool.
Review the availability of CPU pools on nodes as part of your placement policy for
virtual machines on Oracle Database Appliance Virtualized Platforms.
If your virtual machine is assigned to a specific CPU pool, and the virtual machine is
allowed to fail over, then the virtual machine attempts to use the same CPU pool on
the secondary node. If the CPU pool exists on the other node, but the CPU pool is a
different size, then the performance of your virtual machine can be affected when it
runs on the secondary node. If the assigned CPU pool does not exist on the
secondary node, then the virtual machine cannot fail over.
Note:
Do not manage
odaBaseCpuPool
by using oakcli cpupool commands.
Instead, use commands that configure ODA_BASE, as discussed in "How to
Resize ODA_BASE."
