FAST, the File Analysis and Sizing Tool, is a system utility which reduces the staff time required for file maintenance, and ensures maximum system performance and efficient use of disk space.  This robust utility was first written by Jeff Fitzgerald and Dr. Peggy Long in 1983.  Today, there are over 2,000 FAST user sites worldwide.

FAST for Prime INFORMATION Rev 2.0 of FAST was designed specifically to address the dynamic file parameters available in INFORMATION Releases 7 and 8, providing comprehensive analysis and reporting, thorough verification of file integrity, and automated reclaim of abandoned space.              Although not as maintenance-intensive as static files, dynamic files require a different file maintenance procedure.  All processes are menu-driven, with start/stop clocks for after-hours scheduling.

FAST for Prime INFORMATION performs four major functions: file storage reporting, THE BEST selection of file parameters, automatic reclaiming of abandoned space and automatic implementation of tuning parameters for each file.  These four functions are wrapped into a user interface which provides automation and reporting to make FAST a very easy to use tool.  All processes may be executed either through an interactive menu or as background processes.  FAST supports start and stop clocks to provide administrative control of processing times.


FAST is a file maintenance utility for Prime INFORMATION's static and dynamic files.  A FORTRAN program reads each of your data files and counts the data bytes, overhead bytes, abandoned bytes, data records, disk pages and a lot more.  This descriptive data and several performance related statistical calculations are written into an INFORMATION database.  From this database, FAST suggests new modulos and types for static files when needed.  For dynamic files, FAST suggests parameters for SPLIT.LOAD, MERGE.LOAD, MINIMUM.MODULUS, GROUP.SIZE, and LARGE.RECORD.

FAST performs extensive and intelligent analysis on your files.  It suggests new parameters calculated to produce optimum performance and then automatically implements the changes when you choose to proceed.  You may make FAST aware of special situations by setting controls which override system and account level parameters, customizing FAST for your system's special needs.

FAST provides extensive, statistically descriptive reports, documenting important performance-related details about the internals of your files.  Error checking will inform you of certain types of file damage to prevent potential data loss.

FAST fully automates the resize function, based on accurate information and careful assessment of the current file structure.  When needed, FAST performs type analysis, choosing a new file type based on actual modeling of all 16 types available.  Users may schedule task execution to fit their operational schedule, using either our start/stop clocks or phantom processing.  The user retains complete control of the process and can override the FAST recommendations or alter the list of files to be resized.

Which version of FAST is right for you?

FAST is available for Prime INFORMATION, uniVerse on UNIX and Windows NT, and UniData on UNIX and Windows NT.
