Documenting network and terminal requirements
The size of your IMS installation and your terminal profile determine how you document your network requirements.
The terminal profile
Creating a terminal profile is the best approach for gathering the information you need for your system definition. Your terminal profiles also assist you in coordinating the installation arrangements. They help you describe, to the system programming staff, how each terminal is to be used.
Begin by examining the application program specifications or the hardware plans to identify the terminals that are to be used.
Terminals attached using VTAM®
- Binary synchronous communications (BSC)
- Synchronous data link control (SDLC)
- Local attachment (directly to a channel)
When you define your IMS or select an ETO logon descriptor, your choice of terminal type determines the communication protocol and the MFS formatting that IMS uses for that terminal. You can use more than one terminal type for a particular physical terminal; however, your choice must be compatible with the application programs that execute on the IMS.
