(E)JES Systems Management

With (E)JES you can better manage jobs, output, devices, and system resources.

Job Management

(E)JES makes it easy to manage JES jobs, helping you work more efficiently. It gives immediate, up-to-date, JESplex-wide information about jobs waiting to be processed or in execution, such as:

  • Status, class, priority, date and time of a specific job
  • All jobs on a specific queue, such as the input or held output queue
  • Detail for a job, no matter where it is in the JESplex
  • Reasons a job might be delayed
  • Output from a job as it is created, no matter where it is running in the JESplex

You can hold, release or cancel jobs, or change a job's priority, class, destination. You can filter the displays to include the jobs that interest you, or work with all jobs in the JESplex.

Output Management

(E)JES displays detailed information about output ready to be printed, including:

  • Total number of lines to be printed
  • Classes the output is assigned to
  • Forms needed for printing
  • Date the output was created

(E)JES lets you control how and where your output is printed.

Device Control

With (E)JES you have a single interface to some of the most important devices on your system.

  • Local and Remote Printers and Punches: (E)JES displays the status of all printers and punches in the JESplex, their output classes, and information on the job being processed on each device. Using this information, you can better decide how to schedule output for printing.
  • Spool Partitions and Volumes: The Spool Partitions and Spool Volumes panels let you see which partitions/extents are filling and assign overflow partitions and/or move spool extents between partitions to compensate. Simple line commands allow you to drain, hold, use or release spool extents.
  • Functional Subsystems (JES3): (E)JES displays the status of all functional subsystems in the JESplex. Making required changes is easy. And you can invoke the Printer/Punch panel directly from the FSS panel to view the status of each device and functional subsystem application (FSA) associated with a writer FSS.

Network Connections and Servers

(E)JES provides two displays for managing your networks:

  • Network Connections: This display gives information about network connections to an adjacent node, including BSC NJE lines, NJE over SNA, and TCP/IP socket connections, as well as associated receivers and transmitters.
  • Network Server: This display includes information about network servers, including NETSERV devices and BDT instances.

System Resource Management

(E)JES provides an effective way of managing resources, which can help your system run more efficiently.

  • Job Scheduling: The JESplex Parameters, Job Classes, JES-managed Initiators, JES Resource Monitoring, and Job Class Groups displays help you monitor and control job scheduling to make optimal use of system resources.
  • NJE Resources: (E)JES displays the status of each node known to the current JESplex. Simple line commands start, stop, and manage the lines connecting the NJE nodes.
  • WLM Resources: You can display information for all defined scheduling environments or all jobs requiring a scheduling environment, and view and modify the state of each resource on any system in the JESplex or sysplex.
  • WLM Enclaves and z/OS UNIX Processes: (E)JES provides displays for monitoring and managing WLM enclaves and z/OS UNIX processes.
  • z/OS Health Checker: (E)JES provides robust support for managing checks registered to the z/OS Health Checker, including Health Checker History.
  • System Requests: This panel displays all outstanding system requests for the sysplex retained by the Action Message Retention Facility (AMRF). You can delete or respond to these requests.

Problem Management

Problem management often involves reviewing the system log and issuing various system commands to understand the nature of the problem.

(E)JES lets you view the system log online and search for specific information using (E)JES commands. You can also view and filter the sysplex-wide Operations Log.

The system's response to operator commands often fills the system log. With the same information available on full-screen panels, you can issue these commands less often and use less spool space. Problem management is simpler with fewer extraneous commands and responses.

(E)JES also helps you diagnose jobs that appear "stuck" during job scheduling or execution by providing detailed contention analysis reports. Using these reports, you can ascertain which required resources are not available to your job.
