In this course application programmers are shown how, through the use of job control language (JCL), JES3plus control statements can be used to provide special instructions to JES3plus to perform on their jobs during job processing. Also discussed is how deadline scheduling can be implemented to make the best possible use of available resources along with dependent job control which can be used to control the flow of jobs based on specific conditions.
This course is suitable for application programmers that use JCL to execute application programs in a JES3plus environment.
Successful completion of Interskill’s – JES3plus Fundamentals course, or equivalent knowledge.
After completing this course, the student will be able to:
- Identify several different JES3plus control statements
- Discuss what deadline scheduling is and how it is used
- Describe what dependent job control networks are and how to use them
