Re: How big is your z/OS 1.9 root and where does it live

[Hunkeler Peter (KIUK 3)]

>I just ran out of space on my ROOT while installing JAVA 31.$

You should not install directly into the root file system but 
allocate a separate file system for each separate product. Keep
the root more or less as it is delivered with z/OS, except from
creating additional directories to be used as mount points 
for other file systems.

Re: How big is your z/OS 1.9 root and where does it live

[Lizette Koehler]

I place all of my system OMVS data sets on a separate 3390-9 volume.  I have
increased the space on the SYS1.OMVS.ROOT to about 6 trks.  Since I am
not using a top ROOT dataset which just have links in it (the better way to
go), I wanted to make sure I had sufficient space.

I have an HFS Root.
I have an ETC,  VAR,  XML,  SIGYROOT, and temp that fills up the 3390-9 by
3/4s.

I will be eventually redoing my OMVS environment to have a top Root which is
just links and using Symbolics and /&SYSNAME type setups in my BPXPRMxx
member.  This is very well documented in the OS/390 V2.7 Unix Setup manual.

Hope this helps.

Lizette

How big is your z/OS 1.9 root and where does it live

[John Norgauer]

I just ran out of space on my ROOT while installing JAVA 31. I'd like a 
ball-park number  of your size I have 60K tracks and it's 
on my SYSRES. I could re-locate to another volume but I thought maybe I 
could do some clean-up also. Any thoughts?

It's simple, the bits on the 360, et seq. are numbered in the 
same direction as on the 704, etc.

And I really missed the instruction to shift only the sign bit 
from the AC to the MQ.

There's a slight semantic difference.  "Sign" vs. "flag".  Two different
uses of the same high order bit, neither of which is compatable with 
a 32 bit address.

CPU Measurement Facility

[Martin Packer]

It turns out I DO know about this...

I've known it's been in the works for about a year and have had some very 
basic sample data since the Spring.

I'm hoping to get round to blogging about it in a few days. (An urgent 
customer situation and also HackDay 6 on Friday prevent me from spending 
the time right now.)

But I can say these are some rather nice counters provided by the hardware 
that will be externalised in an SMF record. (The SMF record was in plan 
last time I checked - a few months ago and is NOT the SMF 23 that has been 
talked about.)

Re: IBM PR: IBM Launches Next-Generation Mainframe for Midsize Customers

[Marian Gasparovic]

Mark,
high level answer - CPU measurement facility can be switched on from
HMC when directed by IBM. It will collect extra performance data, very
low level stuff, don't ask about details, I don't know.
It was available before in other form which required an outage (I
don't know if POR or partition deact/act), now it can be switched on
and off without an outage.

Re: EXEC PGM=??? to issue operator commands from the JCL stream?

[Roger Bolan]

On my JES2 system, nothing special is needed.  To issue commands that do 
not have to coordinate with job steps, you can just stick them at the top 
of any job. 

For example, when running a testcase that requires me to use a special 
writer proc and destination for a certain printer, I can just insert the 
following lines right above my job card: 

/*$PPRT619 
/*$T FSSDEF(WTRES600),PROC=WTRESRJB 
/*$TPRT619,ROUTECDE=RJB619 
/*$SPRT619 

That stops PRT619, changes the proc, changes the routecde (for DEST), and 
then starts the printer for me.

Since those commands are not synchronized with the job steps, I have a

Re: Probably a basic MQ question

[Bruce Richardson]

We've seen this before. It means that MQ thinks there is something it needs 
to keep track of from that date. It could be a dead or orphaned message. Try 
re-cycling (stop/start) the queue manager to free up the datasets, and then 
manually delete the datasets (if MQ hasn't).
If the re-cycle doesn't do it, try poking around the queues to see if there is

Re: EXEC PGM=??? to issue operator commands from the JCL stream?

[Jon Brock]

We use a program from the CBT tape for this very thing.  

Todd's original need has been satisfied for the moment, as he didn't
need to synchronize commands within a job stream.  Even so, I prefer to
use the program, as differing security parameters at our installation
mean the IEFBR14 method works on the development system but not in
production.

I can't remember exactly which file had the program we use, but I know
it was one from CBT.

Thanks. I've downloaded that book and am giving it a view. Of course, we
only have a single CEC, and run a BASIC sysplex (due to the cost of a CF),
so it doesn't really apply to us. And likely never will.

Re: IBM PR: IBM Launches Next-Generation Mainframe for Midsize Customers

[Marian Gasparovic]

John, Infiniband is used a lot in z10 BC (same in EC). There are four
types of fanout cards from CPC drawer. Only one is non-Infiniband, it
is ICB-4. You have two types of IB-oprical for coupling links and one
IB-copper which connects CPC drawer to I/O drawers. Obviously
connection from CPC to I/O is transparent for operanting system.
Infiniband on z10 does not connect to storage.

There will be System z10 BC Technical Overview (sg24-7632) available
in couple of hours.

I'd suggest Redbook about InfiniBand in z10. SG24-7539-00.

In few words Infiniband is used for copupling links only, so only z/OS 
(and CFCC) can exploit it. So, no VM, VSE, TPF, no Linux.


In fact there are two flavors of IB in z10: fiber optic - for coupling 
links, and copper - STI replacement.

It is also possible to have PSIFB (IB coupling links) in z9, but:
1. Currently only Coupling Facility can use it in z9 CPC
2. To order that feature you have to own z10
3. The speed of PSIFB in z9 is half of z10.

$VS is a JES2 command which basically tells JES2 to issue an MVS command.
Although it is issued by the JES2 address space, the command is processed as
if it were issued by the RACF id under which the job is executing.

This is documented somewhere in the JES2 manuals. Of course, I'm being a bit
parochial in assuming a JES2 system.

Enhanced Application Preservation?

Partial memory restart?

Thanks to everyone. 

I implemented Raymond's suggestion for // COMMAND 'blah' last night, and it
works great.  The unsynchronized behavior is fine for the immediate need at
hand.  I needed to refresh WLM.

John, do you have an example of an IEFBR14 job that would do this?  

I've used PGM=COMMAND before - I wasn't sure of the origin... probably the
CBTTAPE.

The simplest way, but which requires that the INTRDR be set up correctly, is
to do something like:

//DOCMDS EXEC PGM=IEBGENER
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//SYSUT2 DD SYSOUT=(*,INTRDR)
//SYSUT1 DD DATA,DLM='$$'
/*$VS,'D A,L'
/*$VS,'F CICS*,CEMT PER SHUT IMMED'

Re: EXEC PGM=??? to issue operator commands from the JCL stream?

[J R]

It depends if you want the commands synchronized 
with a particular step, or not.  
 
If you don't require step synchronization, you can 
simply include the commands in the JCL, either 
directly or as operands of the COMMAND statement.  
 
However, if you do require step synchronization, you 
will need a program.  Check the CBT tape.

360/370 24bit psw had ILC/CC and program mask in adjacent byte; BAL/BALR
not only saved the 24bit instruction address but also the next byte of
the PSW (cc, and program mask).

on return, not only could the calling/return address be restored, but
SPM instruction would also be used to restore the program mask ... aka
from principle of ops SPM programming notes:

  1. Bits 34-39 of the general register may have been loaded from the PSW
by execution of BRANCH AND LINK in the 24-bit addressing mode or by
execution of INSERT PROGRAM MASK in either the 24-bit or 31-bit
addressing mode.

  2. SET PROGRAM MASK permits setting of the condition code and the mask
bits in either the problem state or the supervisor state.

  3. The program should take into consideration that the setting of the
program mask can have a significant effect on subsequent execution of
the program. Not only do the four mask bits control whether the
corresponding interruptions occur, but the exponent-underflow and
significance masks also determine the result which is obtained.

... snip ..

BAS/BASR were introduced on 360/67 as part of supporting 32bit virtual
addressing mode.

retrenching to 370 ... not only was 360/67 32bit virtual addressing
dropped ... but also the channel controller for multiprocessor support
... standard 360/67 multiprocessor not only allowed all processors to
address all real storage but also all channels.

standard 360 (and later 370) multiprocessor support only allowed two
processors to address all of the (same) real storage ... but each
processor was limited to only addressing their own, dedicated channels.

some of the 360/67 control registers were also used to "sense" the
switches on the channel controller (which governed the multiprocessor
configuration settings ... not only for channels but also for real
storage) ... these control register definitions were later taken over
for "access registers"

Re: IBM PR: IBM Launches Next-Generation Mainframe for Midsize Customers

[Timothy Sipples]

There's more information on the new System z10 BC now available here (click
on the top graphic):

http://www.ibm.com/systems/z

and here:

http://www.ibm.com/systems/z/hardware/z10bc

Here are some of my thoughts

The price reductions jump out. Specialty engines (IFLs, zAAPs, and zIIPs),
with memory, see their pricing slashed by 50%. And these are much faster
engines, so the price-performance improvement is huge. Fastest uniprocessor
(Z01 model) appears to be listed as 673 MIPS (up from about 474 on the z9
BC), a +42% improvement. (Insert standard "MIPS" disclaimer here.) It's a
z10 processor, so it has the new crypto hardware decimal floating point,
large memory pages, etc.

GIGANTIC NEWS! (Sorry, I'm excited. :-)) The LSPR tables are up now.
The Model A01 is 26 MIPS (insert standard disclaimers here), so IBM has
held the line on that, offering the same capacity for its smallest
customers. But the A01's MSU rating is now 3 (down from 4). Hurray! See,
for example, the z/OS 1.9 multi-LPAR table:

http://www.ibm.com/systems/z/advantages/management/lspr/index.html

MSU ratings are used for software charging by most vendors, including IBM.
(IBM already had special A01 software pricing, though.) Your mileage may
vary, but this is interesting. There's "technology dividend" throughout the
capacity ranges, so, as another important capacity point example, there's
an A02 model at about 48 MIPS and only 6 MSUs.

There are many, many more capacity models (for z/OS, z/VSE, z/TPF) than the
z9 BC. It's now A through Z and 01 through 05, still with no gaps. The
capacity steps look a little smaller, so that's good. (More precise
control, relevant for any full capacity licensed software.) And there's
only one hardware model, so you can start at A01 and go all the way up to
Z05 on the same machine. All very convenient.

Minimum memory is 4 GB now, but all of that memory is available for use.
(There is a dedicated HSA, like the z10 EC.) This is very good for smaller
customers with more limited memory demands. Maximum usable memory is 120 GB
for now, but IBM says you can go up as high as 248 GB by June, 2009. (So
there's a higher density memory part coming, obviously.)

There are 10 (faster) main engines available for configuration (up from 7
on the z9 BC), with up to 5 available for z/OS, z/VSE, and/or z/TPF and the
others for specialty engines (zAAPs, zIIPs, IFLs, Coupling Facilities).
There are no dedicated spares, but if you only configure 9 you have a
spare. (Only 8, you have two spares, and so on.) HiperDispatch is supported
on this machine, just like its big brother.

I/O capabilities are really, really interesting on this new machine. Read
through that information for details. In particular, there's some important
upgrade capability that's new and will eliminate planned outages.

Also, IBM announced some important storage-related enhancements, notably
the new "High Performance FICON for System z":

http://www.ibm.com/press/us/en/pressrelease/25586.wss

Details forthcoming on that I assume.
