Calculating Required Cores; Gathering System Requirement Information - Oracle X6-2-HA Deployment And User's Manual

You do not have to select database templates with the same size category as the
ODA_BASE template. For example, you can use a small ODA_BASE template to host
two very small databases, and you can use a large ODA_BASE template to host either
one large with one small database, or host one medium database with one small and
two very small databases.
Caution:
The total requirements for your selected database templates must not
exceed the capacity of your ODA_BASE template. You can adjust the size of
ODA_BASE after the initial deployment, so can expand ODA_BASE to
accommodate more databases in ODA_BASE.

Calculating Required Cores

After you select templates for your planned Oracle Database, identify your workload
type, and determine the total number of CPUs that you require to support the
templates.
Oracle Database Appliance templates are configured and tuned for specific types of
Oracle Database workloads:
• Generic templates
• Online analytic transaction templates (OLTP)
• Decision support services templates (DSS)
• In-Memory database templates
These templates are designed to run on a specific number of cores. Caging ensures
that each database workload is restricted to the set of cores allocated by the template,
enabling multiple databases to run concurrently with no performance degradation, up
to the capacity of Oracle Database Appliance. You can select database template sizes
larger than your current needs to provide for planned growth, which you accommodate
later by adjusting System Global Area (SGA) and Program Global Area (PGA) sizes,
as well as the number of cores.
