    Error in Oracle® Database Reference 11g Release 2 (11.2) E25513-04

      The V$ASM_FILE view description is probably not correct:

       

      In an Automatic Storage Management instance, V$ASM_FILE displays one row for every Automatic Storage Management file in every disk group mounted by the Automatic Storage Management instance. In a database instance, V$ASM_FILE displays no rows.

       

      However in my environment (Oracle Database 11g Release 2) the view does display rows in a database instance, and the rows returned are actually the same as those returned in ASM instance.

          Thanks. I have notified the writer for that book.

            After some testing, we believe that the documentation is correct as written. For example:

            If you still think that the manual is incorrect, can you provide more details?
