Configuration Preferences

The SNA Node Configuration Edit → Preferences dialog displays the following node options:
Auto Start
This option controls whether and when an SNA node is automatically started. The settings are as follows:
  • None

    The SNA node is never automatically started.

  • On Boot

    The SNA node is started when the workstation is booted up.

  • User

    The SNA node is started when any user logs onto the workstation.

Auto Stop
This option controls whether and when an SNA node is automatically stopped. The settings are as follows:
  • None

    The SNA node is automatically stopped only when the workstation is shut down or restarted.

  • TP User

    The SNA node is stopped when the TP user logs off the workstation.

  • User

    The SNA node is stopped when any user logs off the workstation.

  • Last User

    The SNA node is stopped when the last logged-on user logs off the workstation.

TP Context
An SNA Node is responsible for starting Transaction Programs (TPs). This option controls whether a TP is allowed to access a user's desktop. The settings are as follows:
  • System

    An SNA Node is responsible for starting Transaction Programs (TPs). The TP Context System value causes TPs to run with SYSTEM authority and the only workstation that can be accessed is the system console.

  • User

    The TP Context User value allows a TP to access the TP User's desktop.

The TP User is defined as the user who starts the SNA node. If that user logs off the workstation, the TP User becomes the user who has been logged onto the system the longest. If the SNA node was started on boot then the TP User becomes the first user who logs on.
Note:
The TP context is ignored when a user ID is specified in the Local LU definition in the active node configuration.
Default SNA Node Configuration
You can specify a default node configuration (.acg) file.
