Operating System and Language

• A dedicated physical or virtual server is required, running Windows Server 2016 Standard or a later version.

• Windows Server language settings (detailed checks are here):

  • The Windows Server operating system must be set to use the English (United States) language.

  • The Windows Server language for non-Unicode programs must be set to use the English (United States) language.

• Customers who use a separate database server should install SQL Server 2016 Standard or a later version. For detailed instructions on configuring MS SQL, please consult Appendix 1.

Users and Groups

To create a domain user with the specified permissions and ensure the password adheres to the given criteria, follow these steps:

Create the User:

• Open the Active Directory Users and Computers management console.

• Navigate to the appropriate organizational unit (OU) or location where you want to create the user.

• Right-click on the OU, select "New," and then choose "User."

• Follow the prompts to set up the user account. You can use your naming convention, but for purpose of this document, let's call the user "GYTPOLSVC."

Set Password Criteria:

When setting the password for "GYTPOLSVC," make sure it does not contain any of the following characters ', ", ~, ;, commas or spaces

Assign Permissions (optional):

• For a more stringent permission setup, you can create a security group within Active Directory, e.g., "GYTPOL_UI_Access”.

• Add "GYTPOLSVC" to the "GYTPOL_UI_Access" group.

• This group will be used to access GYTPOL UI or system settings during the initial server configuration.

• By default, all authenticated users are granted access to the GYTPOL UI, which can be modified using the Roles and Permissions screen after the initial installation process.

By following these steps, you will have created a domain user, set a password that adheres to your criteria, and established a security group for GYTPOL UI access, all in compliance with your requirements.

Permissions

Follow the below table to set the permissions regarding the user and the group (follow hyperlinks for how to’s):

By following these steps, you can use the Automatic Pre-checker tool to ensure that your GYTPOL server meets the necessary requirements and configurations before installation.

Appendix 1 – SQL Technical Requirements

In this appendix, you will find the technical requirements for SQL Server in the context of GYTPOL installation:

Initial Storage Requirements for Database and Log Files:

• Data: Allocate 40GB of storage for every 10,000 devices.

• Log: Allocate 10GB of storage for every 10,000 devices.

SQL Collation/Character Set:

SQL Server collation/character set should be set to SQL_Latin1_General_CP1_CI_AS.

Database Recovery Model:

Databases' recovery model should be set to SIMPLE after the GYTPOL setup is complete.

Database User:

The GYTPOLSVC user created earlier should be assigned the db_creator role only for the initial GYTPOL setup. The db_creator role can be removed once the setup is complete.

Data Types:

• The system stores data of the following types:

  • OLTP (Online Transactional Processing)

  • OLAP (Online Analytical Processing)

Data Access Method:

Data access method is .Net SQL client.

Unnecessary Components During MS SQL Installation:

• The following components are not required during the MS SQL Server Installation:

  • Full-text engine

  • SQL Server Integration Services (SSIS)

  • SQL Server Reporting Services (SSRS)

  • SQL Server Analysis Services (SSAS)

  • T-SQL

  • Database mail setup

Database Administration (DBA):

The customer will be responsible for standard DBA routines and backups.

These technical requirements ensure that the SQL Server environment is properly configured to support the GYTPOL installation and operation effectively.
