CHAPTER 1
Introduction to UL/SPF
UL/SPF is a family of products implemented as User Language application subsystems
and designed to function together in a Model 204 online. Each product in the family can
be installed and run independently, or each can be installed and run as a component of
the integrated UL/SPF (User Language / System Productivity Facilities) framework.
All UL/SPF products share a common "look and feel" that is modelled upon IBM's ISPF
facilities. UL/SPF supplants the sometimes arcane command language of Model 204,
providing a highly productive full screen interface to a variety of common Model 204
functions. UL/SPF enhances the capabilities of Model 204 and bypasses many of its
restrictions, enabling the performance of routine tasks that were previously impossible or
prohibitively time-consuming.
UL/SPF comprises the following products:
SirDBA A system that analyzes Model 204 databases to determine their logical
structure, populating an internal catalog. SirDBA is distributed as a
component of the Sir2000 Database Analysis Tools.
SirFile A comprehensive facility both for monitoring the physical storage utilization
of Model 204 database files and for warning users of the need for file
reorganizations. SirFile maintains historical information that allows it to
predict when file sizing problems will occur, allowing a DBA to take
preventative action before an application outage results.
SirLib A powerful and flexible system that provides change management and
configuration control for Model 204 User Language applications. SirLib is
fully integrated within the Model 204 programming environment, supporting
unique Model 204 constructs such as file groups, while remaining nearly
transparent to programmers.
SirMon A comprehensive facility for monitoring the performance and availability of
Model 204 online systems. SirMon combines the real time monitoring of
Model 204 performance with intelligent full screen displays that facilitate
System Manager duties.
SirPro A collection of powerful and easy to use tools for programmers, database
administrators, and application managers. SirPro provides programmers
with powerful facilities for managing large libraries of User Language
procedures, and it provides system managers with intuitive ISPF-like front
ends to many arcane Model 204 system management commands.
