Re: File Placement Utility

[Hardee, Chuck]

Thanks all for your responses.

While some of you offered some good ideas on how to handle the problem, none of 
them presented was an automated process, which is what I was hoping for.
Some of you asked questions about types of files and cross LPAR conditions and 
I will not go into those details.
Suffice it to say, I have 1500+ files of varying sizes and I need to balance 
their placement across 70 volumes.

If no one knows of a tool out there that can do this, then you have all 
fulfilled my need.
I will have to, I guess, invent the wheel.

Subject: File Placement Utility

I have a need to juggle the locations of 1500+ files on 70 volumes.
These packs are not SMS managed and will never be.
There will be 4 sets of these files across 4 sets of 70 DASD volumes.

Does anyone know of a utility, REXX, EXCEL, executable program, etc, that would 
let me feed in the file names and sizes, dasd characteristics, etc, and produce 
a list of what files should be allocated on what packs?

The file sizes vary file to file, but they do not expand or contract once 
allocated and won't change until the next time the files need to be adjusted, 
which won't hopefully, change for a while.

Thanks,

There is the option to specify a DDNAME. That would probably make
sense for tape in a batch environment.

But it struck me that what you may be asking for is the ability to
copy an entire tape -- labels and all -- to an AWS file. That is, to
make a portable image of a whole existing real tape. I don't know if
there's a mainframe tool to do that, but there is a standalone
tapecopy.exe available with the Hercules project to run on a UNIX-type
machine that can copy in either direction between real (reel - heh)
and AWS. I used it to copy most of my collection of tapes from the
1970s through early 1990s using a SCSI-attached drive on a Linux PC.

A mainframe (i.e. z/OS) tool would be a combination of one of the
existing tape mapping programs with the trivial code that creates the
AWS file control blocks. Probably someone's done it already.

Ah - yes... It's in the /util directory of the Hercules source.
Download http://downloads.hercules-390.eu/hercules-3.11.zip and
extract tapeconv.jcl . This contains the source code and surrounding
JCL to build and execute it.

Well, here's what IBM has to say:

http://www-03.ibm.com/systems/z/os/zos/tools/java/products/jrio/overview.html

IBM Java Record I/O (JRIO) is deprecated as of SDK 6.0.1. No new function 
will be
added to any release of IBM Java Record I/O (JRIO).

IBM 31-bit SDK for z/OS, Java Technology Edition, V7.1 and IBM 64-bit SDK 
for z/OS,
Java Technology Edition, V7.1 are the last releases to support the JRIO 
component.

We strongly recommend migrating to IBM JZOS Batch Toolkit, which currently 
has
equivalent functionality and will be enhanced with new functions.
...

I see no harsh confidentiality warnings on that page.  But I suppose the OP may 
be
at risk simply by disclosing that he's party to ICNs.

The information that you received is confidential information, and 
CA is under a non-disclosure agreement with IBM. You have 
presumably also signed a non-disclosure agreement so that you 
could have access to that information. By disclosing it here, you 
and CA are both at risk.

If you want to ask questions about this kind of information, you

Why do you say that it can't read files on tape? I haven't tried it,

The history and editing commands are implemented in BASH using an
integrated version of "GNU Readline". The tab completion for commands or
file selection is a part of BASH itself. My suggestion is to run BASH on
z/OS. It is available on the CBTTape (http://www.cbttape.org/cbtdowns.htm),
file 918 is the executable only. File 919 contains both the executable and
ported source.
You can also get the ported source from :
https://github.com/JohnArchieMckown/bash
or the executables, in a z/OS PAX file, via
https://github.com/JohnArchieMckown/bash/blob/bash-4.2-zos/bash-executable.pax.Z
As you may have guessed, I am the one who did this port. This is BASH 4.2
patch level 53. This has the "shell shock" fix installed. You can also
request an alternate port from RocketSoftware:
http://www.rocketsoftware.com/ported-tools/bash-4254
​This latter port seems to be one patch level higher than mine.​

this is a feature of the Shell. Linux uses (mostly) the BASH as default

I'm sorry for the bad formatting. Trying again



I'm adding some pax options as follows:


a) I want the target to inherit all source attributes:


==> pax -rwE -pe -XCM source target


b) I want the target to keep source attributes, except for ACLs (if an) which 
should be set baset on the target environment's ACLs:


==> pax -rwE -ppx -XCM source target




I like to see what's been copied, therefore the -E option




And don't forget that you may need appropriate rights, depending on what you 
intend to do. E.g. setting extended attributes (APF, program controlles, 
sharelib) require access to BPX.FILEATTR profiles.




 copytree can be much lower than pax. Both are much slower that an IDCAMS 
REPRO, which is my preferred option *if* the part being copied is contained in 
a separate file system.

Check the storage critical value in WLM. This is the equivalent of the old 
"PWSS=" parameter in SRM.

Subject: CICS suffering from Page-In delay: Page Stealing versus Paging Out

A word in advance: I have subscribed to the MXG-L list but have not yet granted 
access, so I'm asking here first.



I'm busy working on a problem some of CICS region are suffering from 
periodically. There are times when some CICS regions are paging-in some MB of 
storage and are thus suffering from the paging delay. 


Since this is about page-in, the storage that is paged-out has been in use 
before. It is not too clear yet what this storage is and what is causing it to 
be referenced again in that massive way. That's being investigated and is not 
directly my question here, although any hint is welcome as well.


I'm trying to understand why that amount of storage has been paged-out from 
those CICS regions, and when this has happened. looking at the SMF30 subtype 2 
for the CICS regions a indeed can see intervals with large number of pages 
being paged-out (SMF30PGO). I do not see any non-zero values indicating pages 
had been stolen (SMF30PST). 



It has been my understanding (which may be wrong, of course) that page 
steaqling happens when the Available Frame Queue goes below the min threshold. 
SRM/RSM will them steal pages and page them out. I would expect those numbers 
to appear in SMF30PST. And if this number is 0 for an address space, this one 
was not a donor in a low AFQ situation, right?




We do see the AFQ going low sometimes, and it was my assumption that those 
CICSs were victims by having pages stolen. This does not seem to be the case. 
What then causes the pages to be paged-out (SMF30PGO)? Is CICS doing PGOUT by 
itself?

Re: IBM FTP and the Batch Runtime Environment

[Staller, Allan]

This is old news and has been a statement of direction for about 4 years.



Statement of direction

IBM 31-bit SDK for z/OS, Java Technology Edition V7.0 and IBM 64-bit SDK for z/

OS, Java Technology Edition V7.0 are planned to be the last releases to support 
the

JRIO component. JRIO was deprecated in the IBM SDK for z/OS, Java Technology

Edition, V6.0.1 products. Customers and ISVs are encouraged to use the record 
I/O

facilities in the JZOS component instead of the JRIO facilities. For more 
information

about JZOS, see JZOS Java Launcher and Toolkit Overview

http://www.ibm.com/systems/z/os/zos/tools/java/products/jzos/overview.html

For information about migration from JRIO to JZOS and sample code, see

IBM Java Record I/O (JRIO) to IBM JZOS Batch Toolkit Migration and Sample Code

http://www.ibm.com/systems/z/os/zos/tools/java/products/jzos/

sdk601_jrio2jzos_mig.html

While the deprecation will only be marked in the z/OS Java SE SDK 6.0.1 and z/OS

SDK SE 7 releases, customers are encouraged to use JZOS (instead of JRIO) in the

other existing z/OS Java SE products. For a list of products, see

http://www-03.ibm.com/systems/z/os/zos/tools/java/products/allproducts.html



HTH,





I have received an info (ICN 1422) from IBM they will abandon the Batch Runtime 
Environment.

Do you know whether this has an impact on the IBM FTP server?

Mainly the job submission and getting job output from spool via FTP



ICN 1422:

New z/OS is planned to be the last release where the Batch Runtime Environment 
component of z/OS will be shipped and supported.

Re: CICS suffering from Page-In delay: Page Stealing versus Paging Out

[Ted MacNEIL]

There is an option in the WLM to make a service class memory critical.
It was designed especially for this issue with CICS.
If CICS is not requesting the page out, this will protect all the regions in 
the service class.

AW: Re: Copy a directory structure with copying files.

[Peter Hunkeler]

I'm adding some pax options as follows:
a) I want the target to inherit all source attributes:==> pax -rwE -pe -XCM 
source target
b) I want the target to keep source attributes, except for ACLs (if an) which 
should be set baset on the target environment's ACLs:==> pax -rwE -ppx -XCM 
source target
I like to see what's been copied, therefore the -E option
And don't forget that you may need appropriate rights, depending on what you 
intend to do. E.g. setting extended attributes (APF, program controlles, 
sharelib) require access to BPX.FILEATTR profiles.
 copytree can be much lower than pax. Both are much slower that an IDCAMS 
REPRO, which is my preferred option *if* the part being copied is contained in 
a separate file system.

Thanks. I forgot to add above URL. Much appreciated.

I found also on those pages that you should enter above commands in the BODY of

You've got good replies, but I have more questions:

Are they 'files' or datasets? If datasets, what types are they? VSAM, PS, PDS, 
PSDE, etc.?

Are they cataloged? If so, how are you going to handle duplicates, since you 
said '4 sets of these files'?

Are those volsers shared on other LPARS? If so, are they also cataloged there 
or not?

Do you want to place largest dataset on some volsers and smallest on other 
volsers?
Or do you want to split up your 70 volsers into 4 groups and place your 4 sets 
datasets in each of those groups?

Write your own utility using [print] output from ISMF, ISPF =3.4, DCOLLECT, 
DFDSS with TYPRUN=NORUN, etc.

You can perhaps create a CSV file to edit on your workstation. Easy to sort, 
group, re-sort, split-up your contents based on dsn name, size, volsers, DSORG, 
etc.

You can compact [sort of] them by putting them in groups in one dataset using 
DFDSS. You will save some tracks depending on contents of these individual 
datasets.
