About Over-Subscribed CPU Pools
Configure virtual machines so that they do not subscribe to more CPU resources than
the resources available in CPU pools.
A CPU resource can belong to one, and only one, CPU pool. You can assign multiple
virtual machines to a CPU pool. A CPU pool becomes oversubscribed when the virtual
machines that are active in the pool require more CPUs than you configured for the
pool. For example, if a CPU pool has four CPUs, then you can start two virtual
machines that are defined to use four CPUs each. In this case, the CPU pool is
oversubscribed, because each of the four CPUs is supporting two virtual machines.
If you stop one of those virtual machines, but start another one that requires two
CPUs, then the CPU pool is still oversubscribed. This is because two of the CPUs are
supporting both virtual machines. When oversubscribing a CPU pool, assess the
performance of the virtual machines in that pool. Reassign one or more virtual
machines to a different CPU pool if sharing an oversubscribed pool degrades
performance to unacceptable levels.
Creating a New CPU Pool on Oracle Database Appliance Virtualized
Platform Nodes
Use the command
oakcli create cpupool
to create a CPU pool.
Manage resource use by creating CPU pools, and then assign these resources to
virtual machines.
Example 12-22 Example of Creating a New CPU Pool on Oracle Database
Appliance Virtualized Platform Nodes
This example creates a CPU pool named
winpool
that is allocated 4 CPUs on Node 0:
oakcli create cpupool winpool -numcpu 4 -node 0
Showing the CPU Pools Configured on Oracle Database Appliance
Virtualized Platform Nodes
Use the command
oakcli show cpupool
command to display the CPUs assigned
to each defined CPU pool.
You can use
oakcli show cpupool
to display any virtual machines assigned to
each CPU pool.
