About Database Templates for Oracle Database Appliance
Review this information to help determine the database template to use.
Oracle Database Appliance enables you to consolidate many databases into a single
system. Consolidation can minimize idle resources, maximize efficiency, and lower
costs. By using instance caging in conjunction with Oracle Database Resource
Manager (the Resource Manager), you can provide desired levels of service across
multiple instances on a single Oracle Database Appliance.
Oracle Database Appliance templates are already tuned for the size of each database
instance workload. They 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.
The Oracle Appliance Manager Configurator refers to the database sizing templates
as classes of databases.
Note:
Oracle strongly recommends that you use the Oracle Database Appliance
templates, because they implement best practices and are configured
specifically for Oracle Database Appliance.
Use the database sizing tables to help select the best templates for your databases.
When using the sizing tables remember that:
•
The information in the tables assumes that you are creating disk backups. The
information in the tables assume that you are creating local disk backups.
