This article provides a step-by-step guide for configuring Instance Caging on ODA.

You can consolidate multiple databases using Oracle Database Appliance. Oracle Database provides a method for managing CPU allocations on a multi-CPU server running multiple database instances. This method is called instance caging. Instance caging and Oracle Database Resource Manager support the desired levels of service across multiple instances. Consolidation can minimize idle resources, maximize efficiency, and lower costs.

Oracle Database Appliance templates are designed by default to run on a specific number of cores. You can use instance caging and Oracle Database Appliance to deploy multiple databases on Oracle Database Appliance using Oracle Database Appliance templates that are pre-tuned for the size of each database instance workload. You can also select database template sizes that provide additional capacity for planned growth.


Oracle strongly recommends that you use the Oracle Database Appliance templates, because they implement best practices and are configured specifically for Oracle Database Appliance.
You can use either Oracle Appliance Manager or Database Configuration Assistant (DBCA) to create databases on Oracle Database Appliance. The templates are available with both utilities.
