The OMEGAMON Enhanced 3270 User Interface (e3270UI) offers outstanding capabilities for monitoring and managing the performance of z/OS systems, applications, and devices. It offers modern usability features, such as ISPF dialogs, for a great web-based experience. With e3270UI, you can use Windows standards, including pull-down menus, tabbed dialogs, push buttons, and pop-ups, for better multitasking.
To make the most of the UI, you must be familiar with mainframe environments, keyboard-based commands, shortcuts, and troubleshooting frequent navigation problems. If you are a beginner and have just begun using OMEGAMON e3270UI, you have come to the right place. Read on to learn more!
Efficiency best practices
1. Get familiar with your environment
2. Get acquainted with function keys
3. Use command shortcuts
- Instead of navigating through menus, directly enter known commands. See e3270UI navigation with command lines.
- Familiarize yourself with frequently used shortcuts to save time. For example, did you know the e3270UI supports browser standards including Back, Home, and Search buttons, Hyperlinks, and HTML dialogs?
4. Customize user preferences
Note: Make these changes in your preferred terminal emulator.
- Adjust font size and colors for better readability.
- Adjust the screen size for better display. It is recommended that you use 132 or higher width screen. You can see all the tabular views on one screen with a wider screen.
- Modify session timeouts to avoid frequent disconnections.
Common issues you might face while navigating e3270UI
