RE: IPLing to clear Temp addresses

Rob,

When you do the upgrade from 6.1 to 7.1, make sure you use level RSB
for the I_BASE_01 CD, that has the Technology Refresh PTFs already included
in it, and will not require a second IPL after the upgrade, plus the PTF
installation will take about 1/2 the overall time using RSB vs RSB for your
I_BASE_01 CD.

On your temp addresses, did you try a RCLTMPSTG between IPLs to
reduce some of the storage? (That would show up under WRKSYSSTS Current
Unprotected) I don't think it will reduce the number of addresses anymore,
but it will reduce the space being used.

Subject: IPLing to clear Temp addresses

Jump back into your wayback machine and remember back on CISC machines.
Remember when you used to have to IPL on a periodic basis just to clear up
"% temp addresses"? If you ever maxxed that out you were dead and had to
IPL right then and there. Upgrading to RISC cut our downtimes in half
because "that one machine" no longer had to be IPLed monthly - it could
wait until our every other month regular downtime.

Well, it's been years since I've paid attention to "% temp addresses". Now
I just noticed this on one lpar:
% temp addresses . . . . : 31.173
And this is the info on QCTL (which only gets set at IPL so that's a good
guess on our last IPL date/time):
Entered system:
Date . . . . . . . . . . . . . . . . . . : 08/14/10
Time . . . . . . . . . . . . . . . . . . : 12:24:50
That was a regularly scheduled downtime.
Good news is that this weekend is it's next regularly scheduled downtime.
But if that was normal, then might that not mean this system could go a
maximum of six to seven months between IPL's? Since we IPL every other
month it is no skin off my teeth. But, I suspect there are shops which
might have a concern with this.

This weekend we will also upgrade it from this:
Product ID . . . . . . . . . . . . . : 5761999
IPL source . . . . . . . . . . . . . : ##MACH#B
Release of base option . . . . . . . : V6R1M1 L00
