Installation Requirements

Operating System

Windows

Operating System	Version
Windows	10 (1607 and 1809) and later
Windows Server	2016 (1607) and later

Supported Operating System

Microsoft Visual C++ Redistributable

Open iT requires Microsoft Visual C++ Redistributable for Visual Studio 2022 on Windows systems.

If a compatible version is not yet installed, download and install Visual C++ Redistributable for Visual Studio 2022 before proceeding with the Open iT installation.

.NET Framework

Open iT requires .NET Framework 4.8 or later on Windows systems.

If a compatible version is not yet installed, download and install .NET Framework 4.8 Runtime before proceeding with the Open iT installation.

Unix

Operating System	Version
Red Hat Enterprise Linux (RHEL)	8 and later
CentOS	Stream 9 and later

Supported Operating System

Libraries

• system library libnsl.so.1 and libcrypt.so.1
• libgomp
• chkconfig (for RHEL 9.x)
• libjpeg62 or libjpeg-turbo
• libX11 and libX11-dev

Dedicated User and Group

• Root-level access
• Dedicated User: openit-user
• Dedicated Group: openit-group

File Descriptor Limit

Unix systems typically have a default file descriptor limit of 1024. If you are expecting a lot of distinct Core Server simultaneous users, workstation collector hosts, and license manager collector hosts, make sure that the global limit file is significantly high in the limits.conf file in /etc/security/. If you deem that the configured value is enough, you may keep it as is.

If it is not yet configured or the existing value is not enough:

1. Add the following line in the limits.conf file:

   limits.conf

   <user>  hard    nofile  <new_limit>

   limits.conf Example

   openit  hard    nofile  50000

   This example will increase the maximum open file limit to 50,000 for the openit user.

   warning

   The value of the new limit must be greater than the sum of the distinct number of Core Server simultaneous users, workstation collector hosts, and license manager collector hosts.

2. Change the actual limit in the current environment, run the following command:

   Command Syntax

   ulimit -n 50000

3. Restart the Open iT Services.

   Command Syntax

   /opt/openit/bin/openit-all restart

Synchronized System Clocks

Verifying the time synchronization of the Open iT Core Server and Client is essential to avoid data polling with bad timestamps, which can cause data integrity loss. It is also critical for multiple clients or triad situations, especially over more than one location. NTP (Network Time Protocol) utilities, such as xntpd, are essential for achieving synchronized system clocks.

note

Make sure that the host is reachable by other machines over the network.

note

Open iT supports Red Hat OpenShift Virtualization (KubeVirt).

This enables customers to deploy and manage Windows Server and RHEL-based Open iT components on OpenShift-managed virtual machines, alongside containerized workloads, using OpenShift’s standard provisioning and management tool.

This support has been tested and verified with Open iT version 9.19.450 and 10.2.x.

Component Requirements

The following components are required or recommended for installing the Open iT Core Server.

Required Components

PostgreSQL Database

Starting with Open iT Core Server 10.3, a PostgreSQL database is required for storing operational data.
You may choose one of the following during installation:

• Use the bundled PostgreSQL included with the installer
  The installer will automatically install and configure PostgreSQL. No additional setup is required.
• Use an existing PostgreSQL instance
  Ensure that the PostgreSQL instance meets the following requirements:
  • Supported version: PostgreSQL 14 or later
  • The database server is accessible from the Core Server machine
  • A database is already created for Open iT
  • A PostgreSQL user with sufficient privileges is available

Additional Configuration for a Remote PostgreSQL Server

If the PostgreSQL instance is installed on a different machine from the Open iT Core Server, the following configuration is required to allow the Open iT Core Server to connect to PostgreSQL:

• Update the pg_hba.conf file to allow connections from the Open iT Core Server
• Use the recommended authentication method: scram-sha-256

For detailed information about configuring pg_hba.conf and supported authentication methods, refer to the official PostgreSQL documentation: https://www.postgresql.org/docs/current/auth-pg-hba-conf.html

Recommended Components

Open iT Ingress

Open iT Ingress is recommended to enable access to the Open iT web interface.

You may proceed with the installation without Ingress and configure it later if needed.

Administrative Rights

The Open iT Core Server and Client installation requires Administrative Access Rights to the host machine for successful directory and file creation.

Enabling 8.3 Name Creation

8.3 name creation is a feature that automatically generates short (DOS-style) file and folder names to ensure compatibility with applications that cannot process long paths.

warning

If you are installing the Open iT Core Server on a drive where 8.3 name creation is disabled, or in a directory whose path contains spaces in the folder name (e.g., D:\Program Files\OpeniT), you must enable 8.3 name creation before proceeding with the installation.

If you are installing on a drive where 8.3 name creation is already enabled (e.g., Drive C:), or in a directory without spaces in the folder name (e.g., D:\OpeniT), you may skip this step and proceed with the installation.

Some drives, such as Drive D:, typically have 8.3 name creation disabled by default. This can cause Open iT components to fail when accessing paths that contain spaces. Follow this guide to check and enable 8.3 name creation to ensure the proper installation and operation of the Open iT Core Server.

1. Open a command prompt with Administrator privileges.

2. Check the 8.3 name creation setting for your installation drive. In this scenario, Drive D: will be the installation drive. Run the command:

   Command Syntax

   fsutil 8dot3name query D:

   Example output when 8.3 name creation is disabled

   The volume state is: 1 (8dot3 name creation is DISABLED)
   The registry state is: 2 (Per volume setting - the default)

3. Enable the 8.3 name creation for Drive D:, run the command:

   Command Syntax

   fsutil 8dot3name set D: 0

   note

   This change is not retroactive. Only newly created folders or files on Drive D: will be affected. Existing items will not automatically receive short names.

4. Verify that 8.3 name creation has been enabled on your installation directory, run the command:

   Command Syntax

   for %A in ("<install_dir>") do @echo %~sA

   where <install_dir> is the path of the installation directory.

   Example

   for %A in ("D:\Program Files\OpeniT") do @echo %~sA

   Example result when 8.3 name creation is enabled

   D:\PROGRA~1\OpeniT

5. Proceed with the Core Server installation.
