Tachyon requirements

CategoryRequirementMore details
Tachyon system
  • A complete Tachyon 5.0 (or later) infrastructure is required either in local network or hosted over the Internet.
  • Two-factor authentication must be disabled for either the entire Tachyon environment or for any of the instructions that will be used in ServiceNow.
  • The Basic Authentication feature must be installed on the Tachyon Server (Master Stack), and enabled in the Consumer node of the Tachyon web application.

Tachyon 5.0 - Installing and upgrading

1E Core 2.0 - Preparation: Disable Tachyon Two-factor Authentication

1E Core 2.0 - Preparation: Enable Basic Authentication

Tachyon consumer
  • A Tachyon consumer with the name 1EServiceNowCore must be registered in the Tachyon administration Consumers page.

1E Core 2.0 - Preparation: Add the ServiceNow consumer to Tachyon

Tachyon proxy user

  • A Tachyon user with Actioners role on required instruction sets and management groups, as proxy for the 1E ITSM Connect app user role in ServiceNow.

User must be an AD domain account. This account does not belong to a specific person and can be regarded as a service account, it does not require an email address.

Tachyon roles can be predefined system (Global) roles or custom roles. Global roles have permissions on all instructions sets and all devices. Custom roles can be optionally configured for all instruction sets or limited instruction sets, and all devices or management groups.

Design Considerations: Tachyon Users and Roles

Preparation: Add the ITSM Connect app proxy user to Tachyon

Tachyon administrator

  • A Tachyon user with the Global Administrator role, or one or more users with the following roles:
    • Permissions Administrators role in order to create the above users and assign them to roles. Also create custom roles, and assign them to some instruction sets and management groups.
    • Consumer Administrators role in order to register the ServiceNow consumer.
  • Optionally a Tachyon user with the Global Administrator role, or the following roles:
    • Instruction Set Administrators┬árole in order to upload instruction definitions and create instruction sets
    • Management Group Administrators role in order to create Management groups if desired

Users must be AD domain accounts. The above system roles can be substituted for equivalent custom roles.

Design Considerations: Tachyon Users and Roles

Preparation: Add the ITSM Connect app proxy user to Tachyon

Tachyon license
  • Your Tachyon license should contain the ServiceNow-Integration feature tag.

1E Core 2.0 - Preparation: Check your Tachyon license

ServiceNow requirements

CategoryRequirementMore details
ServiceNow
  • A working ServiceNow instance must be set up. This┬ácan be a demo instance or a production/vendor instance.
  • The following versions of ServiceNow are supported:
    • London
    • Madrid
    • New York

1E Core
  • The latest version of the 1E Core App needs to be installed and configured in your ServiceNow Instance

1E Core 2.0 - Introducing 1E Core

ServiceNow users
  • At least one ServiceNow user for each of the roles in the following table:
    Role nameAdditional ServiceNow roles requiredDescription
    x_1e_connect.Tachyon_Admin<None>

    This role allows its users to configure the 1E ITSM Connect app, in addition to having the same rights as the x_1e_connect.Tachyon_User role.

    ServiceNow admin users must change their application scope to 1E ITSM Connect in order to configure the app, and retrieve instructions.

    x_1e_connect.Tachyon_UserITIL (for access to ITSM incidents)

    This role grants its users access to incidents and the ability to run Tachyon instructions.

    This role maps on to the proxy Tachyon actioner.


    x_1e_connect.Tachyon_Approver<None>

    This role allows its users to approve Tachyon instructions that require approval.


    x_1E_core_connect.user<None>When adding any of the above roles to a user, the x_1E_core_connect.user role is also inherited automatically. Please refer to 1E Core 2.0 - Requirements for more details.
