Oracle Database 19c enables users to change the ownership, permissions, or group membership of a file even while the file is open.

Since this release, the ASMCMD file access control commands, such as chgrp, chmod, and chown, can run even while the file is open. The SQL statements, such as ALTER, DISKGROUP, MODIFY,and USERGROUP commands have also been modified as these SQL statements provide support for these ASMCMD commands.
