Service Context Management for Exertion-oriented Programming Session #, Speaker Name Service Context Management for Exertion-oriented Programming Greg McChesney Thesis Proposal Presentation Computer Science, TTU Greg.mcchesney@ttu.edu 12/4/2018

Overall Presentation Goal or Primary Purpose Create a life-cycle for context management, and update Cataloger to implement the life-cycle. Create a service to execute tasks Greg McChesney Beginning

Learning Objectives As a result of this presentation, you will be able to: Understand the purpose of contexts Understand why a life-cycle is required Utilize the life-cycle for your SORCER projects Create a context in SORCER Modify a context in SORCER Launch a service in SORCER View returned context from the service Greg McChesney Beginning

Speaker’s Qualifications Greg McChesney is a graduate student at TTU Greg McChesney is planning to graduate in May of 2009 with a Master’s in Computer Science Greg McChesney thesis is on Cataloger and creating contexts and jobs in SORCER Greg McChesney Beginning

Did you know? There is no method for creating dynamic Contexts, Tasks, or Jobs in the SORCER environment. Greg McChesney Beginning

Presentation Agenda Background Knowledge What is a Context? Discuss why a life-cycle is required Overview of life-cycle Discuss Task Editor Feasibility Study Demo Schedule Greg McChesney Beginning

Background Knowledge Many different Exertion-Oriented Systems Implementation based on SORCER Created by Mike Sobolewski in 2002 Based on JINI services Framework constantly evolving Interoperability with existing providers a concern for new development Greg McChesney

All About Contexts A Context is a set of instructions for a provider. The context various depending on the provider and the method being executed. Contexts can specify anything about a provider Example: The context for makeDeposit in the AccountTester is: deposit/amount=amount Greg McChesney

Sample Context Greg McChesney Image courtesy of Dr. Sobolewski

Need for a Life-Cycle No method to dynamically create Contexts No method of updating or removing Contexts Exertion-oriented programming cannot be dynamic without Context management Updated Cataloger will provide more accessibility Need Context methods for a task-editor Greg McChesney

Proposed Life-Cycle Implement Context Methods into provider classes New methods will be remotely invokeable Get Create Update Delete Update Cataloger to utilize new methods Greg McChesney

Life-Cycle Explained Context must be: Changes must be Stored locally by provider Reloaded on provider restart Saved on update/create Return blank when none is found Changes must be Compliant with existing providers Provide backup file incase of bad context Greg McChesney

Session #, Speaker Name Need for a Task Editor No common graphical method of creating tasks in SORCER Each provider must have own GUI interface Users must learn each providers interface Provide easier development of new services No method for creating Jobs No method for saving and reusing Jobs.

Edit the Context? Why would we want to edit the Context before we launch the Task? The Context can often described input variables that are not static, editing it allows us to change them. Example: The AccountTester would be useless if you could not specify how much you were depositing or withdrawing. Greg McChesney

Output of the Task Tasks return a Context for their output In the case of a simple Task the output is returned the user In a Job the output is used as input for the next Task Greg McChesney

Use Case-Task Manager Greg McChesney

Feasibility Study Update Cataloger to test Life-Cycle methods Get Context Add Context Update Context Delete Context Utilize provider from Air Force Research Center (Mealstrom) to validate task manager works as intended Greg McChesney
