Configuring a Domain With CPU Whole Cores

The tasks in this section explain how to create a new domain with CPU whole cores, how to configure an existing domain with CPU whole cores, and how to configure the primary domain with CPU whole cores.

Use the following command to configure a domain to use CPU whole cores:

ldm set-core number-of-CPU-cores domain

This command also specifies the maximum number of CPU cores for the domain, which is max-cores. See the ldm(8) man page.

Max-cores and the allocation of CPU cores is handled by separate commands. By using these commands, you can independently allocate CPU cores, set a cap, or both. The allocation unit can be set to cores even when no max-cores is in place. However, running the system in this mode is not acceptable for configuring hard partitioning on your Oracle VM Server for SPARC system.

  • Allocate the specified number of CPU cores to a domain by using the add-core, set-core, or remove-core subcommand.

  • Set the max-cores by using the create-domain or set-domain subcommand to specify the max-cores property value.

    You must set the cap if you want to configure hard partitioning on your Oracle VM Server for SPARC system.
