Re: Anybody besides me notice? -- MIDRANGE-L


My only observation is that newer hardware features in the past  few years
have sometimes 'hit the street' with obvious kinks still not being worked
out.  I would offer the UPS connection cables/lack of PTF to make them
function when the 520s came out, and some trouble that we had with a new
5736 tape controller and it's corresponding SCSI cables as evidence.

I wasn't involved with any HMCs when they first came out, but that was a
pretty obvious one also.

Overall, it's still WAY better than any other company/platform i've ever
dealt with...

No, Joe, that's what Walden mentioned that you never answered.  What I
asked was, is there any quantitative evidence that OS/400 is getting
less stable one way or the other.  And if so, what would that evidence
be?  Number of PTFs issued after a new release?  Number of PMRs opened
by Rob after a new release?  Number of emails on this list complaining
about problems after a new release?

And as you say, there is a similar question for hardware.  It would be
nice if we had actual numbers rather than stories on this list about who
had to replace what, although that does give a feel for it.  Wasn't
there a large batch of 10K or maybe 17K drives that had problems?

Peter, are you suggesting that OS/400 (i5/OS) is less stable?  I

personally

have never opened a PMR, while Rob has raised dozens.  I don't know about
his take on it, but my take is that the system is just as stable as it
always has been, which is far more stable than even the latest release of
Windows.

WebSphere is an inherently less stable beast, but that's the nature of

web

application servers in general.  I will say that I find Tomcat more

stable

than WebSphere 6, but I don't think that's any sort of knock of the

iSeries.


RPG, on the other hand, seems more stable, faster, more powerful.  SQL

keeps

getting better.  CL continues to just plain work.

When's the last time you saw a bug in the operating system?  This isn't
preaching, it's just asking a simple question.

Hardware, on the other hand, IS less stable in my opinion.  It's nowhere
near the failure rate of commodity machines, but it's also worse than I
remember it in years past.

But no matter what, the salient point is that "worse" means that I've had

to

have IBM come in and replace a drive for me twice in the last five years.
How many disk drives need to be replaced on a commodity box?  Hell, I

have

to pretty much replace my laptop every three years.

Nice rant, but you didn't address the part of Walden's post that you
quoted that I found interesting -- has our favorite gotten less stable?
Is there any quantitative assessment that could prove it one way or
another, say # ptfs per release?  Or if we're talking hardware, #
service requests per new model?  Or should I expect more preaching to
the choir, with anecdotes instead of hard facts?
