16. Performance. The DFO subsystem is an interactive data processing subsystem. Data is
received and sent by modem communications. File information is on-line and available for you
to process or query. File updates can occur automatically during or at the end of a process. Due
to file updates or data entry requirements, some DFO processes are time-consuming.
17. Controls. The DFO subsystem uses individual identification codes and passwords to
control system access. The SA is responsible for assigning a code and password to each user.
The AFMIS Computer Operation Manual (AIS Manual 25-L37-AJK-ZZZ-OM) contains
procedures to assign and control passwords for AFMIS.
18. System Environment. The DFO subsystem is designed to operate on an interactive terminal
and modem to access the minicomputer files. The operating system software is UNIX and uses a
basic network utility called UNIX to UNIX System Copy (UUCP) to transfer data between
subsystems. This utility is located in a directory called UUCP Public. The UUCP Public
directory is used to receive and send data files.
19. Hardware Required. The DFO subsystem operates on an AT&T-compatible terminal,
modem, and printer.
20. Software Required. The DFO subsystem uses INFORMIX Run-time application software.
The operating system and application software are included in the DFO package.
21. Contingencies and Alternate Modes of Operation. Continuity of operations (COOP)
procedures for DFO is used when the minicomputer or DFO hardware fails. The procedures
below are general in nature. More detailed procedures should be set up and coordinated between
the SA and all AFMIS users on the installation.
Contact the SA to report any hardware failures and to request replacement hardware.
b. If replacement hardware is not available, you can time-share at an alternate location.
The SA can designate the IFA facility, another dining facility, or the TISA as the alternate
c. COOP procedures for the minicomputer are contained in Appendix E of the AFMIS
End User Manual.
22. Assistance and Problem Reporting.
Operator assistance: Contact the system administrator for help.
