JES2 2.4 (Job Entry Subsystem)
JES2 – System Initialization and Shutdown v2.4
This course describes how and why JES2 evolved and introduces the major JES2 components, their purpose, and general terminology. A number of scenarios are presented that describe how JES2 devices are used, their possible statuses, and how jobs are processed. The final module discusses operational aspects associated with JES2 including how it is automatically and manually started and stopped, and commands that can be used when there are problems with these processes.
JES2 – Monitoring Batch Jobs with JES2
This course describes the JES2 command syntax and provides numerous examples explaining the scenarios in which JES2 commands are used. After an initial overview of commonly used JES2 commands, modules focus on the commands used for displaying printer, initiator, and batch job attributes and status.
JES2 – Using JES2 in Scheduling Batch Jobs v2.4
This course builds from the previous and discusses some of the more commonly used JES2 commands used to manipulate initiator, printer resources and batch job activity. A focus on the JES2 commands associated with modifying batch job attributes as they progress through the JES2 queues is also provided. The display and management of network related JES2 components is also discussed.
JES2 – Identify and Resolve JES2 Batch Problems v2.4
This course provides you with examples of common JES2 batch job-related problems and explains the process and JES2 commands that are used to display, analyze and resolve those issues. Detailed information relating to the function of JES2 checkpoints, their placement, and attributes is provided along with steps required to resolve problems associated with this resource.
JES2 – Identify and Resolve JES2 System Problems v2.4
This course looks at JES2 initialization parameters used to define JES2 system resources and the subsequent JES2 commands used to display and resolve problems that occur with these items. The JES2 shutdown process is revisited in more detail, providing information on problem resolution techniques if JES2 cannot be shutdown gracefully.
JES2 – Command Simulations v2.4
A number of simulations are provided that the student can use to assess their skills and knowledge in relation to the entering of commands, and interpretation of output produced, when monitoring and manipulating the JES2 subsystem and its resources.
JES2 – Advanced – Tips and Tricks v2.4
This course contains many JES2-related tips, tricks, techniques, and best-practice items that you may find useful in your day-to-day activities. It covers several new areas of functionality associated with z/OS 2.3 and 2.4.
