• ASAP Resources
• Internet - http//NonStopAsap.Com
• Manuals - TIM Independent Products CD
• Training - Technical Update Training CD 30
• Presentation Provides Overview of
• Availability concepts
• What is ASAP?
• Release 2.0, 2.1, 2.2 update examples
• Before discussing ASAP
• Its important to understand, why monitor
  availability?
• Its because monitoring increases actual
  availability.
• To understand why, first discuss availability
  concepts.

Dependencies
Availability

• Scenario - Person needs Taxi
• Has No Cash... so needs ATM
• Assumes ATM will be Available
• Availability has many dependencies

Right Card.. Valid Pin.. Remember Pin.. No Line..
Atm Up.. Network Up.. Routers Up.. Server Up..
Application running.. Account valid.. Balance
OK.. Atm ?
4
Is a Relative Notion
Availability

• Scenario - Person in hurry - Has 2 minutes to
  catch Taxi
• If there is a long line, for example Q10
• Even though ATM is Operational
• For User at end of the line
• ATM is NOT Available

5
Service Level Objectives
Availability

• People define Availability according to their
  objectives.
• Formal notion is called - Service Level
  ObjectivesEasy to remember, if SLO not met...
  things slow down.
• ATM Service Level Objectives - Taxi fare
• Status Up
• Queue 0
• Cash 20

6
Varies with Usage
Availability

• User definition of Availability varies with
  usage.
• Definition of ATM Availability is different for
  20 Taxi fare versus 300 Air fare
• Goal ATM
• Status Up
• Queue 0
• Cash 20

7
Depends on Application
Availability

• Availability depends on how you intend to use
  object.
• People define Availability based on their own
  criteria.
• Goal Air Fare
• Status Up
• Queue 0
• Cash 300

• What if Air Fare were 800?
• Would ATM be available?
• Depends on Policy, not Hardware.

Review
Availability

• Availability
• Has many Dependencies
• Is a relative Notion
• Depends on Usage or Application
• Can be defined with Service Level Objectives
• To provide true High Availability Enterprise
• Cannot just Monitor Hardware Operating System
• But must also Monitor Availability of Application
  Domains
• External Monitoring inadequate Apps Hang, Loop,
  Deadlock
• External Monitoring cant know about internal
  domains values
• If Application Domain Service Levels are not
  monitored, its impossible to know when an
  enterprise becomes unavailable.

How does ASAP work?
HowASAPWorks

• Monitors
• Status
• Performance

• Objectifies
• Information into Object-State DB

• Reports
• Results

• Analyzes
• Service Level Objectives
• Determines Availability

13
Monitoring
ASAPMonitoring

• ASAP Monitors both Status and Performance of
  System objects and Application domains
• Status refers to
• Qualitative Attributes, such as Up, Down,
  Warning...
• Performance refers to
• Quantitative Attributes, such as Busy, Queue,
  Rate, ...
• System Objects are
• Subsystems or components, such as File, Rdf,
  Spooler, Tmf,
• Application Domains are
• Abstract Domains of Service, such as
  Accounts\Payable, Funds, Sales, ...

14
Objectification
ASAPObjectification
ATM Cash 150

• ASAP Objectifies
• Status and performance information into
  normalized object-state data base
• Objectification provides basis
• For Analysis and Visualizationof whether objects
  meet their Service Level Objectives.

EDL
ASAP Status Update

• What is EDL ?
• A meta-data language file that defines how
  NonStop Server availability domains relate to
  ASAP features and functions.
• Developers use EDL
• To define how to monitor Subsystem Availability
• To define how to monitor Application Availability
• EDL is not something that ASAP users
• Need to see,
• Understand,
• Or even be aware of

35
Why Care about EDL?
ASAP Status Update

• EDL was designed to define availability
  properties
• However EDL resulted in many additional benefits
• Allows users to have different sets of customized
  ASAP settings.
• Allows entire environments to be archived for
  later reference.
• Observed behavior can be shared with other ASAP
  users. 
• ASAP environments can be mailed to other people.
• Useful for Application and System reporting.
• Both Schema and Data can be stored in EDL files
• Allows an entire ASAP environment to be saved in
  an EDL file.
• Means you can completely snapshot or capture
  situations.
• Means you can snapshot your entire system/app
  configuration.
• EDL Files can be saved, mailed, reviewed, and
  displayed.
