Are you thinking of integrating Aumerial's NTi into your business and have some questions? You are in the right place !

Our FAQ section is here to provide you with clear, precise and useful answers to the questions most frequently asked by our potential customers.

We regularly update our FAQ to reflect the latest product developments and to include new questions that emerge from our user community.

If you can't find the answer to your question, please don't hesitate to contact us directly. Our team is always ready to help you and to enrich this section with new relevant information.

How does Aumerial's NTi license for IBM i work: per user or per server power? Flèche FAQ menu drop down Aumerial

Only one license is required per IBM i partition, regardless of server power.

Once this license has been acquired, the company is free to use it for an unlimited number of users and on as many servers as it wishes, without any restrictions.

How much does the license cost? Flèche FAQ menu drop down Aumerial

The cost of the NTi license is €3,000 ex VAT per year. This price allows unlimited use in terms of users and servers.

How much does maintenance cost? Flèche FAQ menu drop down Aumerial

There are no maintenance costs. NTi has undergone 6 years of research and development, with all bugs and potential problems resolved upstream.

We offer a reliable, stable, and definitive product. We've taken the time necessary to do this, with the aim of eliminating the risk of end-users ending up with incomplete versions. This doesn't mean that there won't be enriched versions over time: they will be available free of charge on NuGet.

We are also committed to maintaining upward compatibility between versions, as is the case with both IBM and Microsoft .Net.

How does technical support work for users? Flèche FAQ menu drop down Aumerial

There is no specific technical support for NTi, as its use does not require any specific technical knowledge.

NTi relies on widespread and universal skills such as languages C#, SQL, and HTML, in addition to the use of an IDE like Visual Studio or its free variant, Visual Studio Code.

Which NTi version should I choose for my configuration? Flèche FAQ menu drop down Aumerial

There is only one version of NTi available, designed to be universally compatible with all configurations without distinction.

What versions of IBM i does NTi run on? Flèche FAQ menu drop down Aumerial

NTi is compatible with all versions of AS400, IBM i, iSeries, as long as a TCP/IP connection and RJ45 port are available.

However, it's important to note that, while it's possible to recover data from older machines, it's not recommended to rely on versions prior to V5R4 (launched in February 2006) for regular enterprise operations.

Which version of .Net? Flèche FAQ menu drop down Aumerial

NTi is compatible with versions of .Net 6 and later and Mono.

Microsoft .Net works on Windows, but what about other environments (Linux, Android, iOS)? Flèche FAQ menu drop down Aumerial

From .Net 6 onwards, it is possible to publish your application on all architectures (ARM, AMD64, X86, ppc64le, etc.) and platforms (Windows, Linux, Android, etc.), as long as they support a .NET runtime, which is now the case for most of them.

What's more, thanks to Docker, any environment capable of running a Docker instance can host a containerized .Net/NTi program. The target configuration is determined when you use the PUBLISH option in Visual Studio.

What third-party software must be installed to run .NET/NTi? Flèche FAQ menu drop down Aumerial

No third-party software needs to be installed to run .NET/NTi.

You can forget about software such as ACS, ODBC, and others....

So how does NTi fit in? Flèche FAQ menu drop down Aumerial

NTi does not require traditional installation. It is simply referenced via NUGET within your current .Net project, using Visual Studio's built-in function.

What about security if NTi can be referenced via NUGET? All I have to do is create an application that accesses an IBM i partition to steal data, for example? Flèche FAQ menu drop down Aumerial

No, because for NTi to be operational, the IBM i partition must be equipped with a valid NTi license key. In addition, access requires a login and password, just like for a 5250 interface.

NTi operates at a very low level, with no dependence on third-party software, giving us complete control over logins and logouts for each transaction

This means there's no risk of a permanent or unintentional connection being left open, preventing the IBM i from becoming a source of vulnerabilities, unlike some products.

How sustainable is NTi? Flèche FAQ menu drop down Aumerial

NTi's future is directly linked to that of IBM i and Microsoft .Net.

Do I need training to use NTi? Flèche FAQ menu drop down Aumerial

You don't need any special training to use NTi. If you've mastered C#, SQL, and HTML, you're already up and running.

If I want to recruit, no one knows NTi and IBM i skills will scare everyone away. Flèche FAQ menu drop down Aumerial

Write your ad like this:

Recruiting .NET Developer
Knowledge required: C#, SQL, HTML, Visual Studio.
Knowledge desired: Docker containerization, ChatGPT.

And that's all, like Monsieur JOURDAIN who wrote prose, your recruit will be working with IBM i and NTi without knowing it.

NTi offers high-performance access to the data on my IBM i, but I also have a whole fund of RPG and COBOL programs vital to my business, with highly specialized algorithms. Will I lose some of my know-how if I adopt .NET? Flèche FAQ menu drop down Aumerial

No, you won't lose your specialized know-how by deploying .Net applications. NTi has been designed to make full use of your IBM i's resources. You can call RPG and COBOL programs, including S36 programs, directly from .Net or Docker, and integrate their results into your C# code.

What's more, you can reuse your stored procedures and web services, and manage message queues...

NTi has been designed so as not to lose any of the richness of an IBM i in a company.

If I use .NET with NTi to modernize my IBM i, am I sacrificing access to advanced technologies such as AI and Cloud architectures? Flèche FAQ menu drop downAumerial

Quite the opposite: keep the intrinsic qualities of your IBM i! By using .NET with NTi, you don't cut yourself off from the latest technologies. On the contrary, it allows your IBM i to benefit from modern advances. Everything .NET has to offer becomes accessible to the IBM i:

  • Containerization with Docker
  • Artificial intelligence with ChatGPT, which masters C# and can automatically generate much of the necessary code
  • Access to various Cloud services, including Microsoft Azure
  • Office 365

.NET serves as a graphical interface for the IBM i, a feature that the IBM i never fully integrated despite numerous attempts.

I've installed Visual Studio 2022, which offers a multitude of project possibilities for different languages, environments and techniques. What projects does NTi support? Flèche FAQ menu drop down Aumerial

NTi is designed to be extremely versatile, supporting all project types offered by Visual Studio 2022, whatever the language, environment or technique chosen.

If I work with several AS400s of different versions, including very old versions, is it possible to manage them simultaneously in a single C# program? Flèche FAQ menu drop down Aumerial

Of course, it's perfectly possible to address several AS400 machines with different versions in the same C# program. For example, you can read data from a machine in V7R5 and write it to a machine in V5R4, or even older versions.

This flexibility is possible provided that the data types are compatible between different machine versions.

After merging with another company, we inherited an AS400 system, but our expertise is mainly focused on SQL Server and Oracle. How can we effectively integrate this AS400 into our current technological environment? Flèche FAQ menu drop down Aumerial

You might indeed wonder about compatibility with your existing environment centered on SQL Server and Oracle.

Fortunately, .NET, capable of handling almost any database, can easily be integrated with NTi. This enables seamless interaction between DB2 for i and the database systems you already use, ensuring efficient collaboration between the different systems.

When implementing .NET to modernize my customer's IBM i, is it necessary to work physically on site to deploy the applications? Flèche FAQ menu drop down Aumerial

Your account management team doesn't need to physically meet the customer to deploy applications using .NET on IBM i.

Everything can be efficiently managed remotely.

Some digital service companies (DSCs) are considering using NTi for their customers. Thanks to its simplicity, integrated approach and lack of versioning constraints, NTi can generate significant savings.

Our IBM i has already been upgraded with various software packages other than NTi and .NET. How will NTi integrate into our existing environment without disrupting our current systems? Flèche FAQ menu drop down Aumerial

NTi has been specifically developed to maintain the collaborative aspect of .NET, allowing a .NET executable to interact with any existing application.

One of NTi's fundamental design principles was to create a product that integrates seamlessly with your existing infrastructure, rather than replacing it.

However, it is still possible to choose to renew and replace your existing systems entirely if this is more in line with your objectives.
