Tenancy Resource Configuration Limits

This section lists the resource limits that are dependent on the appliance architecture. Oracle Private Cloud Appliance supports up to 8 tenancies; these are default limits per tenancy, unless indicated otherwise. The numbers provided here apply to any Private Cloud Appliance installation, regardless of its hardware configuration.

Some of these limits can be customized. See the Viewing and Setting Resource Limits chapter in the Oracle Private Cloud Appliance Administrator Guide.
