z/OS JES Management

(E)JES is a modern tool for managing your z/OS JESplex. (E)JES includes cutting-edge components such as a browser based interface, Zowe conformant API and CLI, and guided z/OSMF installation.

What is (E)JES

(E)JES is a systems management tool that provides all the information you need to monitor, manage, and control your z/OS® JESplex—whether you are running JES2 or JES3. (E)JES panels provide up-to-date information on jobs, printers, queues, and resources in a z/OS JESplex. You can enter (E)JES commands directly from these panels to manage job processes and the operation of system resources.

(E)JES Web

(E)JES Web is a web interface to (E)JES and made available through the same download process.

Every aspect of (E)JES Web has been designed to deliver the best possible performance and user experience. This has resulted in a modern interface that very closely replicates (E)JES response times under ISPF. All (E)JES displays are fully supported.

(E)JES Web is an ultra-thin, fully virtualized client with an intelligent server. Sorting, filtering, searching, and more are performed on the server where the data resides. The client is simply a user interface for requesting and viewing the results of these data manipulations.

(E)JES Web’s intuitive interface is ideal for users new to the mainframe. Dropdown and context-sensitive menus give users access to (E)JES displays as well as options that affect how data is presented on those displays. Most (E)JES Web features are discoverable and online help is available when needed.

The speed and functionality of (E)JES Web make it a useful tool for both power users and novices. Users can select tabular rows and access line commands using only keyboard commands. Traditional 3270 users will find most of the keyboard commands in (E)JES Web instantly recognizable. Typing a single character invokes a command field at the bottom of the display where system, primary, and line commands may be issued.

zOSMF Workflow Installation

The (E)JES installation package includes a z/OSMF workflow that provides expert-system assistance for the installation process. This enables (E)JES installation and initial configuration from the web-based z/OSMF interface without using a 3270 emulator.

Watch a demonstration of an early version of the new installation method in a webinar held in March 2019, z/OSMF Workflow-Driven Installation.
