File Groups; Passwords - VeriFone VX 680 Reference Manual

File Groups

The VX 680 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
•
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 680 terminal.
