My ex-employer actually did, on their second attempt, just before I retired. They were still working on it as I was going out the door. Got out just >< in time. *whew*

The primary concern is transmission speed and possible network latency.


Feel free to send me a message if you want - I've worked for big blue for 22 years as a software engineer for IBMi (formerly AS400) from the comm team to now the OS performance team.

From a general standpoint IBMi fully supports TCPIP - both IPv4 and IPv6. There are many native applications (FTP, secure FTP, SFTP, email, HTTP servers etc). There are also MANY OEM vendors that have applications that can do pretty much anything you want.

It's "just" software. If you have a TCP/IP stack in the OS, there is no reason that software cannot be produced that will do FTP or any other protocol built on top of TCP. There are gigabytes of open source software that implement these capabilities.

This is, probably, more a question of the raw speed of the AS/400 core system, whether there is enough instruction budget to run the system, its applications, and the networking all at the same time. TCP itself is fairly resilient to long latencies, slow data rates, etc. In fact it was designed so. However, user expectations for responsiveness and throughput often exceed the capabilities of the underlying hardware.

I would be surprised if one could not get a reasonable set of TCP-based applications working on an AS/400, the underlying hardware is essentially a Mac circa 2004 which had no trouble running TCP/IP applications. The question I'd ask is "why would you want to?" Sunk cost in applications development, I understand that, but even something like a Raspberry Pi will compute rings around the ancient AS/400 hardware. So find an PowerPC emulator for Linux and don't look back.


I think you greatly misunderstand what AS400/IBMi really is. It's still alive and many of these systems are BIG (10/20/32/64/96 way systems) that many governments, banks, insurance companies, and hospitals run across the globe. This is still an evolving OS and arguably the best DataBase OS that is commercially available (since the OS is designed to be a Database). It's used as a back end DB server in MANY large companies and industries.

Calling power10 hardware a 'Mac from 2004' is laughable. This same hardware runs IBM AIX as well and is ridiculously robust.

sreding, I find your insight and experience with the AS400 very interesting. I had no idea that the system I had heard so much about in my early days was constantly being improved and upgraded right up to now. Your posts got me Googling the system features and hardware.

We got rid of it probably a decade ago.

Reading this thread is definitely a blast from the past of my baby cop years.

I am retired after 40 years in IT. To answer your question on programmers aging out. It isn't limited to the AS400, it is applications written in COBOL. In companies that adopted mainframe systems early on (e.g. banks) there may be some old, much modified, COBOL core systems. Are CIO's nervous? They should be but, in my experience, they make noise about upgrades/replacements then take the money and run to another job. It's the CEO's that should be very nervous since these old systems take years to replace and the skill set necessary to maintain them is diminishing/gone.



Let me help you out. Which way did you come in?

It's funny... every now and then I get some requests from clients for a mainframe programmer systems or applications. Usually they realize they can't afford one. The market is super inflated suddenly due to lack of people that can still do the work. Most have retired and a lot of contractors want $100./hr to even consider it.

While there are still a lot of RPG programs out there 'in the wild' so to speak I don't remember seeing/hearing about any cobol programs in the last few years. I'm sure there are many still out there that are happily plugging along - quite possibly on legacy (i.e. VERY old) hardware, but most IBMi/AS400 customers are now running heavy query workloads and MOST of those are SQL based. There is still some legacy QRY400/OPNQRYF stuff, but we've been trying hard for at least a decade to convince admins to modernize and it's slowly happening.

Most of the 'old timers' have retired - many with very deep skills and the market place isn't replacing those folks. As with most modern IT services - many shops have moved it offshore and the skill of the admins/programmers is lacking to say the least. 'Warm body' comes to mind.

IBMi is still important to IBM and it's customers - you can even spin up instances in IBM's business cloud and there has been a lot of growth there (as you see in all cloud offerings) as available bandwidth continues to grow and IT budgets continue to shrink.
