Multiple File Creation Form

A multiple file creation form is used multiple times to create Oracle ASM files, such as when assigning a value to the initialization parameter DB_CREATE_FILE_DEST. You can also run a CREATE TABLESPACE statement (without a file name specification) multiple times. Each time, Oracle ASM creates a different unique data file name.

When using the multiple file creation form, you can use an incomplete file name form, such as a disk group name preceded by a plus sign (+data). In this case, you set DB_CREATE_FILE_DEST to an incomplete file name (for example, +data), and whenever a command is run that must create a database file in DB_CREATE_FILE_DEST, the file is created in the designated disk group and assigned a unique fully qualified name. You can use an incomplete file name in other *_DEST initialization parameters.
