Title: DRA Corporate Overview


1
QuikConnect
Message Queuing Facility
2
QuikConnect lets different computers and
different kinds of computer talk to each
other. Painlessly and seamlessly. It frees
you from having to deal with FTP, Telnet and
other hands-on applications.
3
The QuikConnect philosophy
Applications should operate seamlessly over the
Internet, regardless of the individual platform
or physical location -- just as applications run
today on host computer operating systems.
4
QuikConnect overview
  • Definition of QuikConnect
  • Client-Server in the Stratus environment
  • Distributed client benefits
  • Implementation using QuikConnect
  • QuikConnect environments
  • QuikConnect flexibility


5
What is QuikConnect?
  • For general computer users
  • Peer-to-peer messaging middleware
  • An efficient protocol for interprocess
    communication
  • An Open Systems transaction-processing facility
  • An interoperability protocol
  • For Stratus users, QuikConnect is also
  • A VOS to HP-UX Solaris migration tool
  • A VOS to HP-UX Solaris porting tool

6
An all-VOS Transaction Processing Facility
Queue holds requests replies
Requester
holds
smsg_send
smsg_receive_reply
  • Can be Intra-host
  • Can be Inter-host via StrataLink or StrataNet

VOS Transaction Processing Facility
  • Requester operations
  • Queues
  • Server operations
  • Multi-Tasking
  • Transaction Protection

10
QuikConnect Transaction Processing Facility
  • Requester operations
  • Queues
  • Server operations
  • Multi-Tasking (supplied by OS)

11
Full Requester-Server model
  • Wait / no-wait modes and means of selection
    of queues
  • Server operations
  • Queue file manipulation commands, including
    VOS s calls
  • Utility commands, including VOS s calls

12
QuikConnect position
  • Because applications should operate seamlessly
    over the Internet regardless of platform or
    physical location, Quik Connect lets applications
    interface freely with and between
  • Windows 95, 98, 2000
  • Windows NT
  • HP-UX, Solaris, Unix
  • Java
  • VOS
  • Other proprietary or open systems

13
QuikConnect user profile
SEC EDGAR Project
TRW, on contract to the US Securities Exchange
Commission, used QuikConnect as the
message-oriented middleware for a large
multi-host, mixed-vendor system. QC is the
glue that interconnects HP-UX, Solaris, Stratus
VOS, Stratus FTX, OS/2, and NT machines for the
Electronic Data Gathering and Retrieval System
(EDGAR) to report all corporate filings to the
US government. It can be viewed at www.sec.gov
14
Competing transaction processing products
  • Single System Image Goal is system-to-system
    portability
  • Blank Paper Applications Best to start
    from scratch
  • Big Environments Similar to operating
    systems

QuikConnect benefits
  • Combines
  • Fault tolerant processing power of the Stratus
    server
  • User interface features of desktop workstation
  • Speed and reliability of a LAN
  • Open Systems architecture
  • Provides
  • High performance access to distributed
    applications
  • Distributed client application processing
  • No required changes to existing server
    applications
  • Access to off the shelf" tools and
    applications
  • More flexible system expansion

20
QC Distributed Client Benefits
  • Takes advantage of PC tools like Windows,
    graphics, imaging
  • Allows application processing without using
    critical server computing resources
  • Applications include image capture, data entry,
    editing, local file access, terminal
    management
  • Improves transaction throughput
  • Data transferred at LAN speeds
  • Processing matched to architecture of computer
  • Breaks application at most efficient point
  • Retains fault tolerant server essential to
    application
  • Provides flexible system expansion

21

QuikConnect offers Stratus users
  • VOS to Unix (HP-UX, Solaris, FTX) application
    migration
  • Servers or requesters can be ported separately
  • VOS Unix requesters can access same VOS
    servers
  • VOS Unix requesters can access same Unix
    servers
  • VOS requesters can access both VOS Unix
    servers
  • Unix requesters can access both VOS Unix
    servers
  • VOS to Unix ports
  • VOS applications can retain VOS-like TPF
    architecture when ported to HP-UX, Solaris or
    FTX
  • VOS users can continue to use familiar TPF
    facilities

22
Target Applications
  • Internet based commerce
  • Point of sale
  • EDI
  • Credit card authorization
  • Mail order
  • Distribution systems
  • Groupware
  • Games
  • Other transaction processing client
    server applications
