Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

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.

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.

To convert Quick I/O files to Oracle Disk Manager files

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.

Shutdown the database.

Run qio_convertdbfiles in the directory containing the mkqio.dat file. The

qio_convertdbfilesscript converts all Quick I/O files to ODM files.

# /opt/VRTS/bin/qio_convertdbfiles -T ora -u

Restart the database instance.

Verifying that Oracle Disk Manager is configured

Before verifying that Oracle Disk Manager is configured, make sure that the

following conditions are met:
