Instance Profiles 

Definition

Instance profiles provide an application server with additional configuration parameters that complement the settings in the default profile. Typically, these parameter settings adapt the instance according to the desired resources. They also define the available instance resources (main memory, shared memory, roll memory, and so on), and how to allocate memory to the SAP application buffers.

Example of a typical instance profile for a double-stack instance:

You can choose any name for an instance profile. The SAP naming convention has the following structure: <SID>_<instance name>_<host name>.
