About Managing Multiple Database Instances Using
Instance Caging
Use instance caging to manage your system resources on Oracle Database
Appliance.
Oracle Database provides a method for managing CPU allocations on a multi-CPU
server that runs multiple database instances. This method is called instance caging.
Instance caging uses an initialization parameter to limit the number of CPUs that an
instance can use simultaneously.
Instance caging and Oracle Database Resource Manager (the Resource Manager)
work together to support your desired service levels across multiple instances.
Consolidation can minimize idle resources, maximize efficiency, and lower costs.
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. Instance
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.
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.
The Oracle Database Appliance Manager interface refers to the database
sizing templates as database classes.
By default, instance caging is not enabled on Oracle Database Appliance. To enable
instance caging, set the initialization parameter,
RESOURCE_MANAGER_PLAN
, for each
database on Oracle Database Appliance. The parameter specifies the plan to be used
by the Resource Manager for the current instance. Setting this parameter directs the
Resource Manager to allocate core resources among databases. If a plan is not
specified with this parameter, then the Resource Manager and instance caging are not
enabled.
