Non-Quick I/O files in a VxFS file system work with Oracle Disk Manager without any changes. The files are found and identified for Oracle Disk Manager I/O by default. To take full advantage of Oracle Disk Manager datafiles, files should not be fragmented.

If you are using Quick I/O files in a VxFS file system and you want to move to Oracle Disk Manager, convert the Quick I/O files to normal files using the qio_convertdbfiles -u command.

You must be running Oracle10g or later to use Oracle Disk Manager.
