Questions?

3. Introduction Problem Motivation Incorporate self-optimization
Testing autonomic computing system during safe-adaptation
Motivation
Apply an autonomic computing system in the context of a real problem
Very little research directed towards dynamically testing AC systems

4. Criteria for evaluation
Survey of tools
Apply container in the context of a real problem
Develop a small component-based adaptable autonomic system
Incorporate a self-optimization capability
Integrate self-testing to be realized dynamically
Integrate tools to support validation of self- optimization

5. Literature Review Safe-Adaptation by Zhang Survey Autonomic Computing
REU 2006 – Autonomic Container
Software Testing
Safe Adaptation with Validation Strategy to Testing AC Systems at Runtime developed by King et al
Safe-Adaptation by Zhang
A system is safe if and only if:
It does not violate the dependencies between components
It does not interrupt any critical communications that could result in erroneous conditions
Survey
Dependency Analysis: JDepend and Cap
Performance Metrics: TPTP
Unit Testing Support: Cobertura and JUnitPerf
Autonomic computing seeks to:
-Automate low level tasks/actions
-Specify behavior as high-level policies
Software Testing
-Supports quality assurance of software systems

9. Implementation Autonomic Manager Framework Managed Resources
Improvement in the use of reflection
Managed Resources
Request Container
Agent Pool
Touchpoint Autonomic Manager
rcSelfConfig
raSelfOptim
Orchestrating Autonomic Manager
oamScheduler
ksScheduler (FCFS and SRN strategies)
What was and what wasn’t implemented…
Look at the code and which classes were implemented and how it works
Set up something with the requests, scenarios,
Pre-Explain stuff for the demo
Idea: show the diagram highlighting what got done and what didn’t

12. Demo Request Container Agent Pool Orchestrating Request Scheduler
Creates the TAMSelfConfig, passing the policy XML file and newly created RequestContainer as parameters
Initializes RMI Server of RequestContainer
Agent Pool
Creates the AgentPool, passing a strategy as parameter
Creates the TAMSelfOptim, passing the policy XML file and AgentPool as parameters
Orchestrating Request Scheduler
Creates the TAMSchedResource, passing TAMSelfConfig, TAMSelfOptim and SchedStrategy as parameters
Creates the OAMReqSched, passing the policy XML file and TAMSchedResource as parameters
This may also be included as part as the previous two slides, since it is part of it.

13. Contributions Survey of tools to support testing adaptive AC systems
The framework was applied in a realistic context
Restructure the existing framework
Integration of self-optimization
Safe adaptation data structure
Developed a complex Autonomic System that contains two Touchpoint AM and one Orchestrating AM.
This may also be included as part as the previous two slides, since it is part of it. 13 13

14. Results of evaluation Incomplete Complete
Survey of tools
Apply container in the context of a real problem
Incorporate a self-optimization capability
Incomplete
Develop a small component-based adaptable autonomic system
Integrate self-testing to be realized dynamically
Integrate tools to support validation of self-optimization
In Process – The publication of two papers
23rd Annuel ACM Symposium on applied Computing (SAC): Autonomic Computing Track Deadline for submission: Sept 8
46th ACM Southeast Conference Deadline for submission: Late November
This may also be included as part as the previous two slides, since it is part of it. 14 14

15. Future Work Integrate safe adaptation data structure
Integrate self-testing framework
Build a fully Autonomic System with self-testing capabilities during safe-adaptation
