Templates are collections of attribute values that are used to specify disk regions, file mirroring, and striping attributes for an Oracle ASM file when it is created. When creating a file, you can include a template name and assign desired attributes based on an individual file rather than the file type.
A default template is provided for every Oracle file type, but you can customize templates to meet unique requirements. Each disk group has a default template associated with each file type.
For more information about Oracle ASM templates, see "Managing Disk Group Templates".
