Re: memory hardware issue

Ah, that's the golden tip that we needed.
A very slow system when no other thing has changed could very much be
a mem stick failure.
My first hardware job was adding some 3096 sticks to a 810... said
sticks were not tested before going to the client, and the one who was
teaching me disregarded the internal lic error that got logged on IPL
AND neglected to see if all the sticks were "operational"
Result?
A production system that was already slow (due in part to the
aforementioned lack of memory) was reduced to a crawl thanks to the
upgrade that was meant to speed things up...
Main system on a healthcare provider, we're lucky they ever bought
from us again.
The machine is losing most of the processor time doing ECC corrections
to the memory sticks, slowing down everything.
Replace or remove soon. Sometimes it's better to lose 4Gb of ram than
to limp around with the ECC corrections.

Best Regards,

Roberto

thanks for the info. will have to pass this on to user with more access.
even though I could dsphdwrsc, i cannot wrksysact or get to service tools.
Our machine was abnormally slow & I was looking for clues.

Does the memory card show failed in hardware service manager?  I suspect
it might.  Any problem reports in Problem Activity Log?

What is WRKSYSACT (yes work with system activity) say you have for
memory?  How about WRKSYSSTS?  Do they agree?  If these show 8Gb then
there may be a bad memory card that did not report in at the last IPL.
I doubt it would failed in service since that would have cause a real
ruckus of messages popping up.

No physical access to hardware.
hardware resources reports:
MS01             313E       Operational           4096MB Main Storage Car
MS02             313E       Not detected          0MB Main Storage Card
MS03             313E       Operational           4096MB Main Storage Car

Could it report this if a card not in the slot??
