Cloning DB2 using Flashcopy

2007-05-22 Thread Tony Wiggett
We have a scenario where we want to be able to clone a DB2 system (using
flashcopy) and then vary off all the disks pointing at the 'original' system
and vary on the 'cloned DB2'. We then want to do some load testing against
the DB2 system. Then when we are finished we want to swap them back again
(and so be back where we started). Is this feasable I can see at least
one problem in that the MVS catalog might get screwed (after reverting back)
if any of the datasets extend while testing on the 'clone' system.

Any advice on this???

Thx
Tony

Hi Tony,
 
Never done it myself but could you take export backup of MVS catalog before you 
start working on cloned system and when you plan to get back to original do 
import back from exported copy. Looks like it should work.

Re: Replacing SAS on the mainframe (Was Report on TSO usage.)

2007-05-22 Thread Robert Bardos
Brian,

SAS licence fees in constellations similar to yours where SAS is
(perceived to be) used mainly for MXG/ITRM purposes are a constant
source of concern in mainframe shops. You will find this topic
being discussed again and again on MXG-L.
  http://peach.ease.lsoft.com/scripts/wa.exe?A0=MXG-L

Al Sherkow posted 'SAS and the zNALC Pricing Metric' a mere two
weeks ago on May 7.
  http://preview.tinyurl.com/2q39wq

SAS Institute (when hard pressed) seems somewhat more willing to
listen to their mainframe customer's licence fee related concerns
than they had been in the last couple years.

As to WPS with MXG on the mainframe I think the only reliably
authoritative source here is certainly Barry Merrill himself. A
google search for 'wps site:www.mxg.com' leads to
  http://www.mxg.com/news/news47.asp

>From following SAS-L, MXG-L, IBM-MAIN I got the impression that
there is a fair number of companies having made the transition
from MVS-based MXG to Unix-based MXG. Only very recently there was
someone mentioning they had gone back to the mainframe (main
reason IIRC had been problems with day-to-day operational
stability).


Hopefully others with real life experience will chime in. You
might get more feedback on MXG-L.

Must admit this question had me confused for a while.
Possibly I contributed somewhat - when I say "targets", I expect people
to understand "O/S target libraries", not "target zone related
libraries".
Target libraries are what your code gets applied into, and (in my case)
invariably reside on the resvol.

Re: Cloning DB2 using Flashcopy

2007-05-22 Thread Brian Peterson
For SAP customers, this is a routine requirement.

Check out IBM Redbook "SAP on DB2 for z/OS and OS/390: DB2 System 
Cloning".

http://www.redbooks.ibm.com/abstracts/sg246287.html

>From the above web page:

-=-=-=-
Abstract 

This IBM Redbook shows the different techniques customers can use to clone 
their DB2 system. Although the scenarios in the book use an SAP workload, 
the DB2 cloning techniques we describe are not specific to SAP. Those 
techniques can apply to any DB2 system and the applications running on that 
DB2. The book describes hands-on details of selected DB2 database cloning 
scenarios, typically the most popular techniques currently used by customers, 
as well as the most efficient scenarios we would like to recommend to DB2 
database administrators.

The scenarios described in this book are based on SAP examples. Our source 
system resides on a DB2 data sharing group. We have one target system 
residing on another DB2 data sharing group and one residing on a non-data 
sharing DB2. All source and target systems are in the same OS/390 Sysplex 
environment.

We discuss and show DB2 system cloning techniques using the following 
methods: 

- ESS Flashcopy 
- DFSMS copy and rename 

The book addresses an audience with in depth knowledge of DB2 for z/OS and 
OS/390 database administration and savy in SAP system requirements.

HLASM calling E/Cobol Response time problem

2007-05-22 Thread Stocker, Herman
G'day list,

We are having a response problem with an E/Cobol module that has just being
converted from COBII.  It is called from an HLASM module not using LE.

Before the conversion the checkpoint were being taken at 20 seconds ( 500
deletes to the data base ( IMS ).  Initial run took that to a checkpoint
every 20 minutes.

We added PREINIT to the JCL this brought the checkpoint time down to 5
minutes.

We have been contact with our local IBM support staff, but I was hopping
that someone would be able to give us some insight.

Thank you.

Yep, moved SAS and MXG onto a dual processor Intel box running Redhat
Linux.  Downloaded all SMF via Gigabit connection, and processed it, and
uploaded reports.  Ran faster, much less expensive, and all SAS programs
ported asis.  Of course, you have to buy SAS for Linux, but is still
much less expensive than MF SAS.

Very easy to do.

That is not an informed view. GRS is the wrong component to make the

The length is in the first 16 bits, not the last 16 bits. For VBS[1]

Close. The limits are imposed by the *SAM control blocks, not by the
DASD. A VBS segment must fit within a block that begins with a BDW,
and the block must fit within a buffer. The limits for VBS were
inherited from those for VB.

[1] Which did not exist when the limits were set.

I started with 3330's.
And, I remember when STK (STC) showed us their first ICEBERG, and the size of 
the device was that of a standard conference table, weighed less and had the 
capacity of an order (or 2) of magnitude larger than the 3330 farm I first 
tended.

That 3330 farm was less than 50 GB, and we were considered a medium to large

Well, no, the best would be for some really good programmer to take
their product and use a "cross platform" GUI toolkit. I have considered
the possibility of taking the x3270 source code (love Open Source) and
seeing if I could make it into a Qt program (Qt is a windowing toolkit
by Trolltech). Unfortunately, I have run into some problems, including
but not limited to (1) lack of understanding of the TN3270 protocol; (2)
lack of understanding the Qt toolkit; (3) lack of talent.

Tony, 

A complete Flashcopy of DB2 and a SWAP to the cloned DB2 system is
simple enough. However If you "(and so be back where we started)" then
shutdown the original DB2 system and restart it once you are done with
the cloned DB2. Just clipped the DASD back and the catalogs are in sync.

Will you bring up the clone on another LPAR ?

Re: Synchronize Time Between Mainframe and Servers?

Behalf Of R.S.
Sent: Tuesday, May 22, 2007 1:20 AM

Subject: Re: Synchronize Time Between Mainframe and Servers?


I don't know microwave owen design, but I can imagine a device working
at - let's say - 3,5GHz +/- 20%. It can be fully acceptable for the
device (like owen) to work at 4.2GHz as well as 2,8GHz. So, resolution
is sub-nanosecond, but the accuracy is very poor. From the other hand
quarts oscillators usually work at MHz frequency, but the frequency is
very accurate and stable over time (months, years).


Yes, we used to call that rock bound (Crystals) [I haven't had an FCC
license at commercial or amateur level since about 1977 -- things
change.] I'm told, but have no experience with PLL (Phase Locked Loop),
that it is also as stable and into the GHz range.

But let us get back on topic. The Mainframe's (at least from IBM's
design), has a TOD that if it malfunctions, is detected and presented as
a machine check. PCs, as far as I've been able to deduce, do not. As a
result, the mainframe TOD has a design that prevents drift (or at least
it did in the TTL days). So much so that in working on ETR designs it
was questioned as to how dithering could be done without causing TOD
error code giving failures. Obviously that microcode had to be changed
to allow an external timer to make the changes w/o causing Clock
Comparator errors (among others).

Sharing the data sets associated with the global zones could also
cause problems. Consider what happens if two vendors assign the same

Got it.  Thanks.  In fact, I had some vague knowledge of the facility, but
not by name, nor how to use it.

How worthwhile is it for an ISV to provide skeleton JCL for the customer
to use in cataloguing with indirect volume references?  (And I note that
some vendors' testing resources might be much taxed by validating such
a facility.)

"NONVSAM".  Is there comparable support for VSAM, or would customers expect
the CSI to be simply catalogued, with multiple TARGET and DLIB zones referring
to indirectly catalogued libraries?  This feels s risky: running an
APPLY or ACCEPT job on the wrong system could be disastrous.  It would feel
safer if all update jobs made direct references to the output data sets,
and any indirect references were read-only.

Thanks again,
gil

I had thought the lockout occurred even before the first invocation

re:
http://www.garlic.com/~lynn/2007k.html#58 3350 failures

silicon valley area had at least three fairly large vm370 customer
datacenters with good sized disk farms ... there was SLAC (lots of
collection from the accelerator) and both Tymshare and internal HONE
operation ... both extensive online, timesharing services
http://www.garlic.com/~lynn/subtopic.html#timeshare

HONE had somewhat started out with a number of cp67 installations to
provide "hands-on" virtual machine use for branch office SEs. recent
reference:
http://www.garlic.com/~lynn/2007j.html#65 Help settle a job title/role debate

It then transitioned to vm370 and lots of online, interactive APL
applications supporting sales & marketing ... i.e. at some point early
in 370 timeframe, there was transition where machine orders couldn't
even be submitted w/o having first being processed by a HONE
configuration.

In the mid-70s, the various (US) HONE datacenters were consolidated in
silicon valley area ... with what was possibly the largest single-system
configuration in the world at the time (large datafarm with load
balancing across large number of processors in loosely-coupled
configuration).
http://www.garlic.com/~lynn/subtopic.html#hone

another large datacenter in silicon valley was Lockheed's DIALOG (online
library titles and abstracts which has gone thru a number of owners
since that time) ... which had something like 300(?) 3330-clones in their
data farm (the basic service was MVS ... but lots of it was run under VM
... on clone processors).

OK.  So a VBS segment is limited to 32760 characters.  But a VBS record
may consist of multiple segments, so need not be limited to 32760.
It appears to me that inheritance was unnecessary, improper, and done
with little thought by the designers.

BTW, JCL and job step allocation, contrary to the JCL RM, by experiment
tolerate RECFM=VBS,LRECL=32761.  Dynalloc, however, reports it as an

Actually a deadly embrance (the old "fatatl fondle") is when
task 1 holds resource A but needs resource B

A job could end up in a fatal fondle if it didn't acquire all its

ISPF Edit Recovery Recursion

Listers,

I will probably cross post later to TSO-REXX newsgroup, but thought I would 
give  this list a chance first.

Somewhere in the last 24 hours something has changed in our ISPF environment.  
We are z/OS V1.7

Now we are now getting a clist recursive error when trying to do an SJ command 
against jobs in the queue.  Now, I know at this time that the error is 
occurring in ISREIRTI.  Which is the EDIT RECOVERY function of ISPF.  What I 
cannot determine is why this is having an error.

I have completely deleted and created a brand new ISPPROF data set.  I still 
get this error.  And I am in the process of checking through the ISPF TABL and 
TLIB data sets to see if a table is corrupted.

Other than that, any other suggestions of where to look?  I have to cancel my 
ID because IBM set this CLIST up as a 999 loop.

OPEN will accept this. If you hard code the LRECL in a DCB

I seem to remember that long ago you could also code this in
JCL, but if this is so, I don't know why it was changed.

I don't remember any 3350 problems as this device type was my first 
performance charge with doing internal pathing/volume placement based on 
performance metrics at timeshare NVIP back in the early 80's. I do however 
remember the 3350 to 3380 migration project which turned ugly when we were 
informed, post migration, that we needed plenum replacements on our 3380 
E's/K's. IIRC the plenum connected to 2 different HDA's but I could be 
wrong on this point.  Lots of long weekends with the media folks deciding 
how to play musical chairs with strings of DASD.

old email
http://www.garlic.com/~lynn/2007b.html#email800402

talks about problem executing HIO/HDV to 3350 when (3880) control unit
was busy (which may have also existing in 3830) ... and software
fix was to i/o supervisor to "not do that".

one of the 3350 to 3380 migration issues was that the 3380 had more data
under each arm (proportional in excess in any increase in 3380 thruput
improvement).

internally we had some performance monitoring and modeling tools that
would identify what 3350 data to move to what 3380  and some
recommendations (in heavily loaded environment) to leave 3380 10-20
percent empty/idle (in order to have same thruput as 3350
configuration).

there was a facetious proposal (even discussed at SHARE) for a special
3380 "feature" in the 3880 controller ... that would define extra priced
3380 drives that were "faster" (by reducing the number of cylinders that
could be accessed). This was for shops where the administrators couldn't
resist completely filling a 3380 as cost effective measure (however,
they would feel comfortable with paying extra for feature that prevented
them from completely filling a 3380).

Assunto: ISPF Edit Recovery Recursion

Listers,

I will probably cross post later to TSO-REXX newsgroup, but thought I would 
give  this list a chance first.

Somewhere in the last 24 hours something has changed in our ISPF environment.  
We are z/OS V1.7

Now we are now getting a clist recursive error when trying to do an SJ command 
against jobs in the queue.  Now, I know at this time that the error is 
occurring in ISREIRTI.  Which is the EDIT RECOVERY function of ISPF.  What I 
cannot determine is why this is having an error.

I have completely deleted and created a brand new ISPPROF data set.  I still 
get this error.  And I am in the process of checking through the ISPF TABL and 
TLIB data sets to see if a table is corrupted.

Other than that, any other suggestions of where to look?  I have to cancel my 
ID because IBM set this CLIST up as a 999 loop.

This happens for most TSO IDs using SDSF with any ISPF function (SJ, SE )

The library SYS1.ISP.SISPCLIB is shared across all environments and we only 
have 3 logon procs.  I can make it fail consistantly on one system.  On another 
I cannot make it fail for the same ID.

I have tried copying the clist to my private library, copying the proc, and 
then placing my lib at the top of SYSPROC.  This does pick up the correct copy, 
but does not fail.  So I am searching the SYSPROC list to see if there is 
another copy of this clist.

What does that mean, exactly?  Is that an IMS specification of some kind?
AFAIK, using the Language Environment preinit facility can't be done with
just a JCL change, it requires you to modify the calling non-LE HLASM
program to use the CEEPIPI subroutine to do each of the following:

1. Initialize a "main" or "sub" LE environment for the E/Cobol routine
2. To call the E/Cobol using the pre-initialized environment and
3. To terminate the pre-initialized environment at EOJ.

Re: Replacing SAS on the mainframe (Was Report on TSO usage.)

2007-05-22 Thread Scott Barry
You may also find that IT Security and Audit personnel have another opinion 
about the importance of
maintaining secure SAS information, if it involves Accounting/Chargeback or 
Cost Allocation data for
your enterprise entities.  And if you are forced down this path, it's important 
that everyone (maybe
even including your information end-users) give their buy-in to the 
transformation (ideally in
writing as in a documented project-execution plan), when considering 
information access, security
and possibly admin learning-curve.

As Robert Bardos mentioned, SAS Institute (not just in North America, by the 
way) is taking
license/contract negotiation more seriously for MSUs-based mainframe SAS 
licensing but I expect that
it's going to need to come from your company/organization to determine what's a 
reasonable license
fee for some "not to exceed" software usage limit.

Perhaps he should file for a TM or Registered TM with the PTO. If M/S
has already done so, he could have grounds to challenge and it might be
a very quick action.

But then I remember Lindows who rolled over and became Linspire even
AFTER the judge in the case stated that M/S could NOT perfect a generic
name into a TradeMark. Seems the money was a bit too good to pass up
(but there were more out of the country lawsuits as well).

Re: Recommend Coax-Attached Consoles?

2007-05-22 Thread Bob

Let's see if I can reply to everyone at once:

Ken – thanks for the info. However, we are trying to move to some sort
of newer technology.  We have lots of  the old stuff.  In particular,
we want the multiple-sessions-on-one-display capability.

Ed/Glenn – So far, the Visara UTC-L is the one box we are considering.
I'm trying to find out if people who have them are happy with them
and, also, what competing products are out there. And Glenn – thanks
for the feedback on the Visara terminals.  They are our current best
choice so I am happy to see that you like them.

Radoslaw & Glenn – let's see if I can answer your questions somewhat together:

1.  Why coax and not Ethernet?  Primary, the ethernet network and
switches are out of our control. If we have a network outage we do
*not* want to lose all of the consoles to 50+ MVS images all at the
same time! We are in an old building already replete with a coax
infrastructure so it works for us.  In other places in the building we
rely on baluns.  If something goes wrong with any of that it affects
only one terminal at a time, not everything together.

2.  Our HMC's & SE's are on the corporate ethernet network. We
recognize that as an exposure.  However, our need to access the HMC's
is somewhat limited and the SE's for the processor are directly
accessible by simply walking into the computer room.

3.  Windows vs. Linux vs. "something else" – We are trying to avoid
Windows for a multitude of reasons – virii, updates, licensing, lack
of support, to name a few.  We want these to be consoles and just
consoles.  Operations will have PC's available that will allow them to
log onto TSO, read email, and do general office "stuff".  That is not
what these machines will be for.  The reason I am asking my questions
is to see if anyone is familiar with any new devices that are still
primarily MVS consoles.
As for Linux, that is not as big of a concern, but for longevity we
would prefer a box that does not have moving parts like a hard drive.

4.  The 10 sessions & 4 sessions are for two different situations.  The
consoles I'm looking for are primarily for the 4 session capability.
I want to help the operators to see 4 sessions on one screen.  The 10
is the total number of sessions that can be configured on one coax on
the Visara controllers. We would like these consoles to support this
capability as well.

5.  The keyboard issue is again because these are consoles.  If we can
get console-type keyboards for them then that is a good thing.

6.  The "no mouse" is again because these are meant to be consoles.  We
are trying to put a lot of these in one place and mice just take up a
lot of desktop real estate for no reason.

7.  One of our options is to stay just the way we are.  However, after
15-20 years the keyboards and monitors on IBM 3471's start to get a
little worn out so hopefully we will find a good alternative for the
future.

Thanks everyone!

Re: RES: ISPF Edit Recovery Recursion

2007-05-22 Thread Schwarz, Barry A
If you have an ID it does not fail on, you might start by looking at
what is different: DSN concatenation sequences in each DD name, edit
options (TSO PROFILE command), edit profiles, etc.

You could add "CONTROL LIST CONLIST SYMLIST" near the top of your copy
of the CLIST so you can watch what is happening.  You might also try
allocating a couple of appropriately named datasets manually just to
make sure something didn't change in SMS and friends.

Does it still fail if you turn RECOVERY off?

That is the problem.  Change the Assembler caller to LE conforming
Assembler if at all possible.  You are building up and tearing down
the environment with each call.  I would also look at whether the
Assembler program still needs to be in Assembler and the difficulty of

Got it.  Thanks.  In fact, I had some vague knowledge of the facility, but
not by name, nor how to use it.

How worthwhile is it for an ISV to provide skeleton JCL for the customer
to use in cataloguing with indirect volume references?  (And I note that
some vendors' testing resources might be much taxed by validating such
a facility.)

"NONVSAM".  Is there comparable support for VSAM, or would customers expect
the CSI to be simply catalogued, with multiple TARGET and DLIB zones referring
to indirectly catalogued libraries?  This feels s risky: running an
APPLY or ACCEPT job on the wrong system could be disastrous.  It would feel
safer if all update jobs made direct references to the output data sets,
and any indirect references were read-only.




There is no indirect catalog support for VSAM.  The closest you 
can come is to place a user catalog on the volume with the VSAM, 
have that catalog own all the VSAM data sets on the volume, and 
use indirect aliasing to find the catalog.  Do a search in the 
AMS book for the "SYMBOLICRELATE" keyword of the DEFINE ALIAS 
command.


Note also that you cannot indirectly catalog a data set in JCL. 
You must use the IDCAMS DEFINE NONVSAM commmand, along these lines:


//STEP EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSINDD *
  DEFINE -
NONVSAM( -
  NAME(data.set.name) -
  VOLUMES(&SYSR1) -
  DEVT()) -
CATALOG(user.catalog.name.if.needed)

You could also use the IDCAMS ALLOCATE command to allocate the 
data sets and set up command return code checking and 
conditionally run commands to accommodate restart, etc., as we 
did in ServerPac's ALLOCDS job a while ago.  This is cleaner--if 
more complex--than using IEFBR14, which will have condition code 
zero whether or not the data sets got allocated and cataloged (or 
not) as you intended.  If you go this route, why we use SSAs in 
ServerPac will quickly become apparent. ;-)


In my opinion:

- DDDEFs should not point to cataloged data sets on production 
systems.  Instead, even though the catalog entries for system 
residence target volume (sets) should be indirect to allow master 
catalog reuse and make migration/backout easier, the DDDEFs 
should point to specific volumes (with a unit of SYSALLDA just in 
case we ever introduce another device type).  Also, the DDDEFs 
for the production copy should point to a volume that does not 
exist to avoid inadvertantly running APPLY against the active system.


- From a software packaging standpoint, if your software lives on 
the sysres target volume set you should provide support for 
indirect cataloging using system symbols.  People can define 
system symbols based on the value of the system-supplied &SYSR1 
symbol for the IPL volume to point to data sets on &SYSRn volumes.

Re: RES: ISPF Edit Recovery Recursion

2007-05-22 Thread Lizette Koehler
Barry,

I have gone as far as copying the Logon Proc (It is the same on all systems) 
and editing it down to just the ISPF and SDSF libraries (SYS1.ISP.SISP and 
SYS1.ISF.SISF) and it still fails.

I had copied the IBM clist to a new library and placed it at the top of 
SYSPROC.  That works fine and I have no failures.  It seems that there is 
something unique in this one system.  Since I cannot complete the SJ command 
(or SE) I am unable to get to the point that allows the REC OFF command to be 
issued.  

I am starting to think of VLF, PDSMAN, or LLA as a possible culprit.

I cannot seem to find the function that is causing this craziness.  So I have 
opened an ETR with SDSF L2 for assistance.  Since the failure only occurrs in 
SDSF and not regular ISPF, I started with them.

I know that SDSF is invoking ISPF Services (like Edit Recovery) for SJ and SE 
functions.

If I get an answer, I will let everyone know.

IEF236I ALLOC. FOR MODKEEP STEP   
IEF237I 3ECA ALLOCATED TO SYSUT1  
IEF142I MODKEEP STEP - STEP WAS EXECUTED - COND CODE

... but VTOC listing does not show the data set.  As I read
the " 12.19.11 Summary of Disposition Processing" in the JCL

it fails with:

No, it answers the question following the refutation stated in your post: 
Why doesn't initiator/terminator downgrade the ENQ from EXC to SHR when the
job has only DISP=SHR interest in the dataset for any of the remaining job
steps.  The answer clearly distinguishes where the deficiency lies in the
system (GRS, not Allocation).

If the question is "why isn't there a RET=CHANGE variant for altering EXC to

Nope.

Wishful thinking.

But why not?


ENQ RET=CHNG only supports 'upgrade' from SHR to EXC, not 'downgrade' from
EXC to SHR.  DEQing and re-ENQing may put you behind some waiting request,
which would expose you to deadly embraces.


Can you PLEASE explain why there was/is support for a SHR->EXC 
Upgrade (which has an almost 100% probability of not being doable due 
to some other task sharing your SHR ENQ status - IOW: Will only work 
when you are the sole ENQ'er in the first place) when the 100% 
Guaranteed to Succeed EXC->SHR Downgrade (since all it entails is 
updating the ENQ E/S field to SHR and acting as if you were the first 
SHR waiter with some OTHER task having just done the DEQ - IOW: You 
keep the ENQ but now as SHR and all the tasks who were waiting for 
you to DEQ [up until the first EXC waiter] get released)?


What was the original justification for the SHR->EXC support (even 
though it has timing restrictions that make it impossible to use 
consistently) while the design DELIBERATELY excluded EXC->SHR support 
that will ALWAYS work and would prevent the unnecessary holding of 
the EXE lock in Job Steps when only a SHR is needed (as well as other 
cases where a user written task needs to start with an EXC ENQ but 
only needs a SHR ENQ for the rest of the job step once the EXC 
protected work has been done)? As others have pointed out the 
rectification of this design flaw/decision is mired in the need to 
insure that the attempt to issue this request on a system that does 
not support it is detected and dealt with. If pushed, I think I can 
come up with a macro expansion that will be able to check for the 
support (by chasing and CVT anchored chain) and issue an ABEND when 
needed although it would be a major kluge of an expansion. The 
alternative, as noted, is to come up with an updated ENQ/ISGENQ parm 
list that will trigger an error if feed to a downlevel ENQ/ISGENQ 
routine.

Since as I noted, the Support is easy to add (as I documented) and 
there is no downlevel exposure if it is initially restricted to use 
by the Initiator (just update the Initiator Code to do the EXC->SHR 
downlevel ENQ at the point where all subsequent steps are DISP=SHR). 
Both the Initiator and ENQ support will be at the same level so you 
do not run into the attempt to run the new code against an old ENQ or 
the macro parm support that would occur if it were a USER-CODE 
supported feature. That Initiator update might actually take a few 
man-days (in addition to the man-hour or so to the ENQ code). You can 
postpone the availability to USER-CODE via new ENQ/ISGENQ macros 
until the problem of handling the accidental attempt to issue the 
request on a downlevel system is addressed. I think that a automatic 
business case can be made just based on the improved efficiency of 
the Initiator.

See Robert Rosenberg's recent well-reasoned contribution on this
topic:

   Linkname: Re: Why is there JOB scope for DSN ENQ's anyway?
URL: http://bama.ua.edu/cgi-bin/wa?A2=ind0705&L=ibm-main&P=195906


So, I'd have to guess, based on the insulting tones, that you and Mr.
Rosenberg have some resentment about this function not being implemented.


I do not regard my query about why this glaring design flaw in ENQ is 
not being addressed (even if the usage of the enhanced support is 
restricted to the Initiator initially) as insulting (or do you regard 
my characterization of the original/current design of ENQ lacking a 
EXC->SHR Downgrade capability as "poor"/"flawed" as insulting?).


I am doing exactly what a SHARE Requirement is supposed to do - Point 
out a lack of functionality and provide an suggestion as to one way 
to rectify the lack. I do not have access to the SHARE Request List 
but I'd be surprised if there has not been one already submitted (or 
at least proposed) about this exact issue (the lack of a EXC->SHR 
downgrade at the job step boundary between DISP=OLD and DISP=SHR 
steps).


IMO, the lack of a fix in progress amounts to a deliberate crippling 
of the Initiator since the fix is so easy to make (so long as you 
make ENQ part initially an Authorized User facility and restrict its 
user-base to the Initiator). If you feel that my estimates of the 
ease of writing the needed code understates the effort needed, I 
welcome your estimate of the effort and/or pointing out where I am 
mistaken about what needs to be done.

Re: DISP=(MOD,DELETE)

2007-05-22 Thread Chris Mason

Paul

You got my attention with the subject line, DISP=(MOD,DELETE), since I used 
to encourage students to consider using this "trick" in order to immunise 
their JCL against irritating errors when they had usually started task 
procedures relating to networking products and they didn't care whether or 
not a data set existed when the task was started. The types of data sets 
involved were for traces, logs and dumps.


Typically the started task procedure had an IEFBR14 step where the data sets 
were definitely erased if they happened to exist - from, typically of 
course, any previous execution - using the DISP=(MOD,DELETE) "trick". The 
IEFBR14 step was then followed by the "business" step.[1]


What you show in fact is DISP=(MOD,KEEP).

An explanation - not at all necessarily *the* explanation since it's very 
much a guess - for the IEF285I message is that, with DISP=MOD, logically the 
data set is considered to exist and thus it can logically be "kept". 
However, with, DISP=NEW, the data set is considered *not* to exist - and you 
get another error presumably earlier in the processing sequence if it does 
exist - and so, before it can be "kept", it must actually be created. In 
order to be created, the SPACE parameters are needed.


So *I* understand it. Of course whether or not I understand it correctly is 
quite another thing!


Chris Mason

[1] Of course the "business" step program needed *not* to have the SYST 
attribute specified in any SCHEDxx member - but that's another story - see

Do the same test for SMS-managed dataset. You'll get JCL error in first case 
(MOD for non-existent dataset).

OMHO the only thing to understand is: When you use NEW for DASD dataste, you 
have to specify SPACE. MOD can behave as NEW, the same requirements apply.

Actually, this was recently explained to me by IBM. (MOD,DELETE)

it does not, then create it and then delete it. But SPACE would be 
required in any case where the dataset did not exist. This would also 
be true for (MOD,KEEP). In this case, if the dataset did not exist it 
would be created, and KEPT, but not cataloged.  SPACE would be

Actually, the explanation is clear, but false. 
Despite of what IBM said, just repeat Gil's test. 
In fact, I did it already, and have to self-correct my previous mail:
The devil is in catalog. 
If you specify unit and volser, SPACE parameter in not required. 
If you don't specify unit 7 volser - that mean you want to use catalog, then SPACE is mandatory for non-existent dataset. Obviously SMS-managed dataset are cataloged, so my previous answer was "almost true" as IBM answer above 



BTW: Anytime I think that nothing in JCL can surprise me, I see new posting from Gil. 
Gil, you are JCL entomologist, thank you for that!

Re: DISP=(MOD,DELETE)

2007-05-22 Thread Chris Mason

Doug

You quoted the my previous post and you didn't retain my quoting of Paul's 
original post so your post is a bit difficult to follow by itself.


In fact, Paul's original post indicated that a data set which did *not* 
exist was kept although not actually created - and so the SPACE issue did 
not arise. It was this conundrum for which I made a hesitating attempt to 
try to provide a resolution.


If you've only just discovered this "trick" - pointed out to me many years 
ago by a guru from the Washington Systems Center - perhaps this example can 
show you how it may be used:


//NET PROC
//*
//IEFBR14 EXEC PGM=IEFBR14
//NCPDUMP DD DSN=USER.NCPDUMP,DISP=(MOD,DELETE),
// VOL=REF=SYS1.PARMLIB,SPACE=(TRK,1)
//*
//NET EXEC PGM=ISTINM01,TIME=1440,REGION=2048K
//STEPLIB DD DSN=SYS1.SSPLIB,DISP=SHR
//VTAMLST DD DSN=USER.VTAMLST,DISP=SHR
//VTAMLIB DD DSN=USER.VTAMLIB,DISP=SHR
//DD DSN=SYS1.VTAMLIB,DISP=SHR
//NCPLOAD DD DSN=USER.NCPLOAD,DISP=SHR
//NCPDUMP DD DSN=USER.NCPDUMP,DISP=(NEW,KEEP),
// VOL=REF=SYS1.PARMLIB,SPACE=(TRK,(1,50),RLSE),
// DCB=(RECFM=F,LRECL=512,BLKSIZE=512)

It would appear that all the years I was using this "trick", I may not have 
needed the SPACE=(TRK,1) in the first step.


Note that I was obliged to include TIME=1440 on the EXEC statement since I 
was obliged to remove SYST from the SCHEDxx entry for ISTINM01.

according to "12.19 DISP Parameter" in the JCL RM (z/OS 1.8):


If the system obtains unit and volume information for an OLD, MOD, or SHR
status, the data set is treated as if it exists, whether or not it is
physically on the device. 


and the "4.6.2.1.8 Disposition Processing of Data Sets that Do Not Exist" in
the JCL UG (z/OS 1.8) says:


When VOLUME and UNIT Are Coded: When you code VOLUME and UNIT on the DD
statement, a JCL error will occur if the problem program attempts to open
the data set. Otherwise, the data set disposition depends on the DISP normal
termination disposition: 


When the normal termination disposition is KEEP, the job log will show that
the data set was kept.

Really no need.  There are several Linux-compatible 3270 terminal emulation
products.  A very professional-grade one is IBM's: WebSphere Host

cross-platform GUI.  It's now Version 10, and IBM didn't skip any numbers
to get there.  Also works on Mac, Windows, and even UNIX clients.

I think this issue came up before on IBM-MAIN, so there's probably some
more discussion in the searchable archives.
