A single file creation form is used to create a single file, such as a data file or a control file. The form of the Oracle ASM file name in this type is either an alias, such as +data/orcl/ctl.f
, or an incomplete file name, such as a disk group name preceded by a plus sign (+data
). You use the alias or disk group name where a file name is called for in a SQL statement, such as CREATE
TABLESPACE
, CREATE
CONTROLFILE
.
