This section explains capacity-on-demand licensing for Oracle Database Appliance X5–2.
Oracle Database Appliance X5-2 consists of two servers. Each server has 36 CPU cores. By default, Oracle Database Appliance ships with all cores enabled on both servers:
36 CPU cores enabled on each of the two servers
72 enabled CPU cores
You can use the default CPU core count of 2 for each server, or you can change the CPU core count by following the procedure in "Setting the CPU Core Count on Oracle Database Appliance X5-2 Bare Metal Deployments". For example, if you change the CPU core count to 18 for each server, then:
18 CPU cores are enabled on each of the two servers
You have a total of 36 enabled CPU cores
Rules and Restrictions for Setting CPU Core Count on Oracle Database Appliance X5-2 Bare Metal Deployments
Review the following rules and restrictions before changing the CPU core count:
You can change the CPU core count to a value that is a multiple of two between 2 and 36 for each server.
If you change the CPU core count, then you can subsequently only increase the CPU core count.
For example, if you change the CPU core count to 28, then you can subsequently change the CPU core count to 30, 32, 34, or 36. If you later change the CPU core count to 34, then you can subsequently change the CPU core count to 36.
If your desired CPU core count is 36 for each server, then use the default configuration. There is no need to follow the procedure in "Setting the CPU Core Count on Oracle Database Appliance X5-2 Bare Metal Deployments" to set the CPU core count to 36.
Note:
If you mistakenly followed the procedure to set your CPU core count to 36, thereby preventing you from subsequently increasing your CPU core count, and the error is caught immediately, then contact Oracle Support.
