One way to use Quick I/O is to create a symbolic link for each file in your database and use the symbolic link to access the regular files as Quick I/O files. Any database or application can then access the file as a raw character device.
See the Veritas Editions product documentation.
The following example creates a 100 MB Quick I/O file named dbfile
on the VxFS file system /database
that can be accessed through a symbolic link.
To access a file through a symbolic link
$ dd if=/dev/zero of=/database/.dbfile bs=128k count=800
The dd
command preallocates the file space.
$ ln -s .dbfile::cdev:vxfs: /database/dbfil
