Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

Perhaps a story in the making....


In 2 years or so my company is purchasing a new computer system for our distributing business. Right now, we have an AIX 5.3 machine and some other servers that I admin. I do not have a college degree. My tech knowledge is mostly experience. I have not studied or read many tech books. I do not know any programming languages or how to design a database.

Not to mention, the commands, interfaces, etc. on IBM i look absolutely nothing like *nix kin and closer to some foreign computer creature from genius world.

The system we are supposedly getting in 2 years is an IBM I OS mainframe. I tried to find tutorials for IBM I. I have not had much luck. I saw classes on IBM's website but the topics were on acronyms I did not recognize. What will happen? What should I do?

Shenanigans ensue. GO! Smilie

So you've risen to your level of incompetence.Smilie

Once you get past the acronyms, IBM has by far the best printed documentation.

I thought your company figured out how to bend & go back in time Smilie if they do and there's vacancy please let me know Smilie

Only now i got it: "IOS", not "I OS". Actually this is not a mainframe but a midrange system, just like the p-series - in fact it is the same hardware.

This system was formerly called "AS/400" and the OS "OS/400" and you will find probably a lot more under these terms than under "IOS". Most of it, even the most outdated information, will probably still apply because the system hasn't changed that much for the last 20 years.

The AS/400 is quite radically different from anyother machine (for instance it has a linear address space which spans memory AND disk space - you move a file and it is dumped from memory to disk) and getting around the concepts is probably quite hard first.

On the other hand the AS/400 is famous for needing next to no administration at all. There are many companies owning a AS/400 and having had no Sysadmin for the last 15 years. Try that with a Unix system, it would be long broken.

The network is an alien thing too: it is called 5250 and works similar to (but is still different from) the SNA system and the 3270 data stream the IBM mainframes use.

Now for the good news: because IOS systems work in p-Series hardware there are still VIOS and HMC and they work absolutely the same way as you are accustomed to. Just the LPARs running IOS are different (inside - they are still the same LPARs from outside, say, from the viewpoint of the VIOS or the HMC).

I hope this helps.

Well, this is quite true: first, all the output command go in the first column. Then all the branching commands go into second column, then all the computing commands go into the third column, .... How the compiler is able to figure out in which succession to execute all these commands is everybodies guess.

In fact there is only one true rival in obscureness for RPG2: APL2. ;-))
