Allocating cooked file spaces on UNIX

The following procedure shows an example of allocating disk space for a cooked file.

1. Log-in as user informix: su informix
2. Change directories to the directory where the cooked space will be located: cd /usr/data
3. Create your chunk by concatenating null to the file name that the database server will use for disk space: cat /dev/null > my_chunk
4. Set the file permissions to 660 (rw-rw----): chmod 660 my_chunk
5. You must set both group and owner of the file to informix:

   ls -l my_chunk  -rw-rw----
     1  informix   informix 
     0  Oct 12 13:43 my_chunk

6. Use onspaces to create the storage space or chunk.
