Which two statements are true about ASM default templates?
A.
Default data file templates are only created by ASM when a normal redundancy disk group is created.
B.
Default template settings for redundancy depends on the disk group redundancy.
C.
Default templates for a disk group can be modified.
D.
Default template setting for striping depends on disk group redundancy.
E.
Templates may be shared across disk groups.
Explanation:
Templates are used to set attributes of files created in an Oracle ASM disk group.
When a file is created, redundancy and striping attributes are set for that file based on an explicitly named
template or the system template that is the default template for the file type.
When a disk group is created, Oracle ASM creates a set of default templates for that disk group. The set
consists of one template for each file type (data file, control file, redo log file, and so on) that is supported by
Oracle ASM. For example, a template named ONLINELOG provides the default file redundancy and striping
attributes for all redo log files written to Oracle ASM disks. Default template settings depend on the disk group
type. The default template for data files for a normal redundancy disk group sets two-way mirroring, while the
corresponding default template in a high redundancy disk group sets three-way mirroring. You can modify these
default templates.
