Converting Quick I/O Files to Oracle Disk Manager Files
If you plan to run VERITAS Storage Foundation for Oracle with Oracle9i or later, and you have
been using Quick I/O files, it is recommended that you convert your Quick I/O files to regular files.
This should be done after you upgrade VERITAS Storage Foundation for Oracle.
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 Oracle9i or later only.
▼ To convert Quick I/O files to Oracle Disk Manager files
1. 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. Run qio_convertdbfiles in the directory containing the mkqio.dat file. (This script
converts all Quick I/O files to ODM files.)
# /opt/VRTS/bin/qio_convertdbfiles -T ora -u
4. Restart the database instance.
Note Because 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.
