Preparing Existing Database Storage for Oracle Disk Manager
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. See “Understanding
Fragmentation” on page 76 for information on defragmenting a file.
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. See “Converting Quick I/O Files to Oracle Disk Manager Files” on page 133 for more
information.
If you plan to convert to Oracle9i or later, convert your database and then migrate your storage to
VxFS files.
