Re: Idea: Using SCRT to report on Linux usage; maybe a way to reduce the entry level cost for Linux on Z?

2018-04-13 Thread Gibney, Dave 
I FIND THIS DISCUSSION TROUBLING. It will not likely ever affect me of my 
installation, has we haven't (and unfortunately are not likely to) used zLinux 
and Z/VM. 

But, is the z/OS MIPS/MSU pricing model (IMO, one of the major drags on the 
platform) really being extended into this arena.

Re: Idea: Using SCRT to report on Linux usage; maybe a way to reduce the entry level cost for Linux on Z?

2018-04-13 Thread Stuart, David 
I run SCRT on my z/VSE Systems, and have been for a couple years, or so, now. 
So, no, SCRT isn't just for z/OS.

Isn't the ibm tool just for z/os and at the LPAR level?  nothing to do with 
what goes on inside z/vm.  nothing to do with what goes on inside linux for 
specific licensing.

I've been asked to provide such information by another vendor, and that 
function will be released shortly.  This allows the 4 hour rolling average for 
linux servers (x or z), pools of linux servers, groups of linux servers, and 
can be done for applications inside linux as well.
It can also be used for VSE if anyone cares.   So I've led the horse to
water.

I don't know if IMLT allows non-IBM software accounting, but that seems
like a great idea to me if it's not already available. Try here if you

Be sure to look for preexisting ILMT RFEs that might be similar before
opening a new one.

IBM also already has sub-capacity licensing for z/VM, also via ILMT.

Re: RHEL 6.9 servers getting Unknown program exception: 0028 SMP

2018-04-13 Thread Bill Bitner 
Rick,
As we discussed on phone, but for benefit of others. My last append forgot
to point out that the TRACE needs to be done for all the virtual processors
in the virtual machine. Otherwise only, only the base VMDBK is protected.

This can be done by using the "CPU" command:
CPU ALL CMD TRACE PROG 28 NOTERM NOPRINT RUN

I apologize for giving both of us a fright and for those following along.

Regards,
Bill

Re: RHEL 6.9 servers getting Unknown program exception: 0028 SMP

2018-04-13 Thread Rick Barlow 
The circumvention of using the TRACE PROG 28 did not work for us. We had
some servers that failed and could not re-boot - most likely related to the
trace being active.
We are booting Linux back to the older kernel level that was not
experiencing the problem - 2.6.32-696.18.7.el6.s390x.
Clearly there seems to be something on those late kernel patches that makes
the servers susceptible to this problem.
I am also pushing to get at least one LPAR IPLed with VM65414 installed.
