Veritas Storage Foundation 5.1 SP1: Storage and Availability Management for Oracle (5900-1504, April 2011)

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.

files
If you plan to run the Veritas product with Oracle10g or later, and you have been
using Quick I/O files, Symantec recommends that you convert your Quick I/O files
to regular files. This should be done after you upgrade.
Note: If you are running an earlier version of Oracle (Oracle 8.x or lower), you
should not convert your Quick I/O files because Oracle Disk Manager is for
Oracle10g or later only.
The Oracle Disk Manager uses the Quick I/O driver to perform asynchronous I/O,
do not turn off the Quick I/O mount option, which is the default.
To convert Quick I/O files to Oracle Disk Manager files
1
As Oracle DBA, run qio_getdbfiles to retrieve a list of all datafiles.
$ /opt/VRTS/bin/qio_getdbfiles -T ora -a
The list is compiled in a file named mkqio.dat.
2
Shutdown the database.
3
As Oracle DBA, run qio_convertdbfiles in the directory containing the
mkqio.dat file. The qio_convertdbfiles script converts all Quick I/O files
to ODM files.
$ /opt/VRTS/bin/qio_convertdbfiles -T ora -u
4
Restart the database instance.
