To create a Quick I/O file using qiomkfile

1. Create a 100 MB file named dbfile in /database:

     # qiomkfile -s 100m /database/dbfile

   The first file created is a regular file named /database/.dbfile, which has the real space allocated. The second file is a symbolic link named /database/dbfile. This is a relative link to /database/.dbfile via the Quick I/O interface. That is, to .dbfile::cdev:vxfs:. This allows .dbfile to be accessed by any database or application as a raw character device.

   • If you specify the -a option with qiomkfile, an absolute path name is used, such as the following:

     /database/dbfile points to /database/.dbfile::cdev:vxfs:

   See About absolute and relative path names.

2. Change the ownership of the /database/.dbfile file to oracle:dba:

     # chown oracle:dba /database/.dbfile

3. Check the results:

     # ls -al
     -rw-r--r--    1 oracle   dba  104857600 Oct 22 15:03 .dbfile
     lrwxrwxrwx    1 oracle   dba 19 Oct 22 15:03 dbfile -> .dbfile::cdev:vxfs:

   or:

     # ls -lL
     crw-r-----  1   oracle  	 dba 			43,0			 Oct 22 15:04      dbfile
     -rw-r--r--  1   oracle  	 dba 			10485760 			Oct 22 15:04  .dbfile
   

   • If you specified the -a option with qiomkfile, the results are as follows:

     # ls -al
     -rw-r--r--   1 oracle   dba  104857600 Oct 22 15:05  .dbfile
     lrwxrwxrwx   1 oracle   dba 	31 Oct 22 15:05 dbfile ->
                                   	/database/.dbfile::cdev:vxfs:
