Oracle ASM Dynamic Volume Manager (Oracle ADVM) Known Bugs

These are known bugs for Oracle ASM Dynamic Volume Manager (Oracle ADVM) in Oracle Database 12c Release 2 (12.2).

Bug 21878915

If this directory location is part of the search string when Oracle ADVM volumes are present, negative interactions between the Oracle ADVM driver and its local Oracle ASM proxy instance can result.


Do not include the directory location used to store Oracle ADVM volumes in the specification of ASM_DISKSTRING. These volumes are for the use of the Oracle ACFS file system. The directory locations vary by operating system platform:

  • For the Windows system, the directory is \Device\Asm.

  • For other systems, it is /dev/asm.
