This section describes the ASMCMD Oracle ASM File Access Control commands. For information about Oracle ASM File Access Control, see "Managing Oracle ASM File Access Control for Disk Groups".
When administering users with ASMCMD, the users must be existing operating system users and their user names must have corresponding operating system user IDs. However, only users in the same cluster as the Oracle ASM instance can be validated.
When modifying ownership of files, the previous owner of a file cannot be dropped while the file is still open even after the ownership of the file has changed.
Table 10-67 provides a summary of ASMCMD Oracle ASM File Access Control commands.
