Creating user descriptors

User descriptors provide information relating to user options and user structure names. IMS needs user descriptors in order to create control blocks that enable users to use ETO terminals.

The three types of user descriptors are:
  • Installation-created
  • Node user
  • DFSUSER

IMS chooses the first valid descriptor, using the given sequence. IMS creates DFSUSER and node user descriptors using system definition options.

This topic describes how to create user descriptors.
