To access an existing regular file as a Quick I/O file on a VxFS file system

Access the VxFS file system mount point containing the regular files:

$ cd /mount_point

Create the symbolic link:

$ mv filename .filename

$ ln -s .filename::cdev:vxfs: filename

This example shows how to access the VxFS file dbfile as a Quick I/O file:

$ cd /db01

$ mv dbfile .dbfile

$ ln -s .dbfile::cdev:vxfs: dbfile

This example shows how to confirm the symbolic link was created:

$ ls -lo .dbfile dbfile

-rw-r--r-- 1 oracle 104890368 Oct 2 13:42 .dbfile

lrwxrwxrwx 1 oracle 19 Oct 2 13:42 dbfile ->

.dbfile::cdev:vxfs:
