Oracle ASM File Access Control provides optional protection for the content of Oracle ASM disk groups from accidental access by unauthorized Oracle ASM clients, such as an unauthorized database.
To set up Oracle ASM File Access Control, you must designate separate operating system groups as described in "Using Separate Operating System Groups for Oracle ASM Users". Oracle ASM File Access Control is available for Linux and UNIX computers only.
You can manage Oracle ASM file access control with ASMCMD commands and SQL statements.
