File Groups
The VX 675 operating system implements a file system in memory. Files are
assigned to one of 15 groups for access control. Groups are similar to directories
on a computer in that different applications can be stored in separate file groups,
just like different computer applications can be stored in separate directories.
Groups are referred to as Group n or GIDn throughout this manual.
Each group is protected by a separate password, and each has a separate
CONFIG.SYS file. The following rules apply to the VX 675 file group system:
The primary application must be downloaded into Group 1.
On terminal power up and after a restart, the terminal defaults to Group 1 as
the controlling group.
Group 1 applications have access to files stored in all groups. Other
applications can reside in Groups 2 – 14.
Applications in a group other than Group 1 have access only to themselves
and files stored in Group 15.
Group 15 is globally accessible, making it an ideal location for files shared by
multiple applications, such as shared libraries.
File Groups 1 – 15 are empty until they are filled through a download to the
VX 675 terminal.
For more information on managing file groups, refer to the Verix eVo Volume I:
Operating System Programmers Manual -VPN DOC00301.
Passwords
Handle passwords as you would PC passwords.
CAUTION
If you change a password but forgot it later on, there is no password recovery
method. Without the password, you are unable to access Verix Terminal
Manager operations and may be prevented from requesting a download,
performing remote diagnostics, or changing any of the information already stored
in memory. The terminal can, however, continue to process transactions in
normal mode.
If you forget or lose the system password to your terminal, please contact your
local VeriFone representative for assistance.
NOTE
Passwords must be in numeric characters only and must be greater than five
digits and less than 10 digits in length.
