Why havent't you converted to a much more stable server like Apache, with Tomcat or WebSphere, or BEA Weblogic? These servers were designed with commerce in mind and the CERN server was NOT. It seems to me as though your'e using a pair of pliers when you should be using a box end wrench and getting mad when the bolt head gets stripped. -----Original Message----- From: Andrew Borts [mailto:Andrewb@SETACORPORATION.com] Sent: Tuesday, July 30, 2002 12:54 PM To: web400@midrange.com Subject: RE: [WEB400] What happened to rpgenerationx.com? We actually worked with the IBM folks to try and resolve it, and set thread count accordingly to their suggestions - which varied greatly. I even theorized that the AS/400's built in security could have thought the Firewall was starting a Denial of Service attack against the AS/400 so I either Disabled or enabled this functionality and tested this way. Once we'd cover one hole, another one would appear. It was VERY ugly. There wasn't a single smooth E-mail blast the AS/400 [E-mails sent to between 200 thousand customers and 1 million customers] could survive without going down. Everyone gets all fired up when I state that the AS/400 IS a very reliable system - TRUE - and it IS a very robust operating system - TRUE - but the HTTP server isn't as reliable, and darn close to sub-par in it's reliability. When they had days of "Big E-mails" I setup the Management Central to monitor the system, and BEEP if the performance level of the system would drop to about 1% (the system was up 24x7 and we always had a steady stream of about 300 people an hour hitting our systems between Midnight and seven am.) When the HTTP server stopped responding, there was no message, no warning (other then the drop in performance) and no customers. Only thing to do was end & re-start the damn thing - NOT the STRTCPSVR *HTTP RESTART(*HTTP) that would FAIL half the time. I setup Brad Stones GETURI program to surf the site, and when the response dipped to about 2 minutes response time, I knew I was having a problem (since the norm was sub-second response) - I would get paged when these problems existed. If I didn't do this, by the way - my partners would page me too - so there was ALWAYS a need to fix problems and prevent new ones from EVER happening. The same pattern STILL exists Nathan - the GENX site dropped for NO REASON, and the ignite 400 site drops for no reason. Is fiddling with the controls of the dang thing the option? Is switching to Apache the option? I'm going to make this statement now and forever more. IBM doesn't WANT the AS/400 to become the next WEB anything. It's a back end system. There is NO rack mountable AS/400 nor will there ever be one (IBM please prove me wrong!). There is a rack mountable RS/6000 - remember the system made of roughly the same stuff as an AS/400?!? So I can't cluster the systems in a rack, as people do with Dells, and RS/6000's and now Mac's. I still need a kick butt Load Balancer in front of a bunch of TINY systems (which don't exist in the AS/400 world!) so I can take the traffic, or have the redundancies that naturally exist in the smaller server world. I can't save space unless I buy that HUGE MONSTER rack with a slider capability built in, which gives me a whopping total of 2 AS/400's where I can normally have about 20 Dells, or even 5 RS/6000's. So when I want to Co-locate (which I have done to get more communications) an AS/400 - I spend significantly more per month because I'm sitting in open floor space or sitting on a special shelf constructed for AN AS/400... To play in this arena, Apache seems to be the answer - because of HIGHLY available HTTP serving support there, but HTTP classic server is being dropped like a hot potato soon (V5R4/5?) so I wonder exactly how much DE-bugging and support we're going to get as time draws end of it's lifecycle... The AS/400 is a perfect communications box - great for B2B, but B2C is only for LIGHT shops only, and only if you HAD an AS/400 anyway.

Andrew, This sounds like it may be related to the number of threads your HTTP Server was running. Normally an IE client requires two (2) threads, and a Netscape client may require up to twelve (12) threads. Do you recall the number of concurrent users you were trying to support, and the threads you were running? Nathan M.

This is a common problem with HTTP server classic (I don't know if it happens on Apache) on an AS/400... The 400 takes connections and then instead of answering, it starts failing, and instead of answering slowly - it craps out... The pattern is CPU usage is THROUGH the roof while the world creams us, then CPU usage drops to almost nothing, while the system TCP/IP connections rise un-answered. It then (after about 2 minutes or so) comes back to life, but it's not the same - you then END & restart the server and it works again. This was something I noticed with a HIGH volume hitting fast and furious.
