RACFICE2 CERTEXP DFSORT

[Sankaranarayanan, Vignesh]

Hello All,

This is more of a SORT question than RACF or certs, so posting here.
Below is the 'CERTEXP' JCL member in RACFICE2 that shows all certs that are 
expiring in the next 'n' days.
//USER01I  JOB MSGLEVEL=(1,1),NOTIFY=&SYSUID,CLASS=A,
// MSGCLASS=H,REGION=19M

It shows the cert "name", which is some eye-blurring text.
I've dug through the IRRDBU00 record layout notes and found the following
# 0207 User certificate name record

I request your help to merge all cert-related record types from IRRDBU00 
(hopefully just the ones listed here - 0207, 0500, 0560, 0561, 0562, 1560), and 
dedupe it based on the unique cert "name" field.
Once done, I need help printing out all the other fields mentioned above so as 
to get a table of all certs with all related info in a readable format (a CSV 
would be great!).
And finally, the ability to filter the output based on 'n' days, so that I can 
see what certs are expiring in the next 'n' days.

Thank you so much for your help, I'm hoping this will benefit many folks on the 
list.

Vignesh,


There is an earlier discussion similar to your requirement  which dealt
with user events. Here is a link to that topic

https://groups.google.com/d/msg/bit.listserv.ibm-main/V-Im5LCmV7Y/5T9yzeVOAgAJ

You can follow the same approach for your record-types and build 1 common
record format and pad it with spaces for the missing values.

You can use SUM FIELDS=NONE to eliminate the duplicates.

If you have trouble converting that sample, Please send me a sample of the
input (1 record per type at the least) and I can show you a way to do it.

Thanks,
Kolusu

I guess. But, given that I'm on z/OS 1.12, I can't make the member to be
select a value on a PROC.

I'm giving up on this. I'm just royally P.O.'ed with the vendor anyway
right now.

Well, then, an IEBCOPY step to copy the PDS to a temporary PDS, 
then a step to read the member from the temporary PDS.

Re: What's the intent of the "LOAD AND ZERO RIGHTMOST BYTE" instruction?

[Mike Schwab]

Well, the hardware does move a 256 byte area aligned on a 256 bytes
boundary very efficiently.  And would allow you to load the register
with an address without storing the last byte.  So a storage pool with
allocation of multiples of 256 bytes would greatly helped.

Not sure if possible, but i would give a try to jcl refer back. Step 1 use
the dd as dummy, but run a rexx to free and allocate the right ddname with
a member name received from jcl parm.
Step 2 reference the dd, but it is now a different name.

Re: USS script : how to test that a MVS Dataset exists ?

[Jerry Callen]

(Another "too late" reply. That'll teach me to go on vacation.)

This script illustrates how to do it, but I'm not sure it would work early in 
the IPL sequence (since it needs to run TSO commands):

#!/bin/sh

if /bin/tsocmd "listd '$1'" >/dev/null 2>/dev/null ; then
  echo "$1 exists"
else
  echo "$1 does not exist"
fi

Re: TSO REXX -- find absolute generation # from relative?

[Lionel B Dyck]

I have REXX code that uses LISTC to find the latest fqdn but that isn't always 
desired even if it is the only way.

I just created an RFE requesting LISTDSI provide support for relative GDG - 
please add your vote

Re: TSO REXX -- find absolute generation # from relative?

Try the following:

/* Rexx  - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - */
/* determine the absolute generation of a GDG*/
/* Execute the rexx passing it the GDG Base and the relative */
/* generation number */
/* generation number */
/* ex ABSOLGDG GDGB(GDG BASE) GEN(0) */
/* Note:  if you don't specify GEN, it will default to 0 */
/* ex ABSOLGDG GDGB(GDG BASE) GEN(0) */
/*   */
Trace "N"
ddn  = "DDN"
gdgb = "SYSGM.CA.OPSMVS.DATASET.BACKUP"
gen  = "0"

parse upper arg 1 'GDGB(' gdgb ')'   ,
1 'GEN(' gen ')',
1  parmstring

parse upper var parmstring parmstring
If Pos('DEBUG',parmstring) > 0 Then trace i

If gdgb = "" then
 do
   say ""
   say "GDG Base Missing, Rerun REXX and Specify GDGBASE(gdg base)"
   exit 16
 end

If gen = "" then
 do
   say ""
   say "GEN not specified, defaulting to relative generation zero"
   gen = 0
 end

rtrc = BPXWDYN("ALLOC FI(DDN) DA('" || gdgb || "("gen")')" ,
   " SHR REUSE  RTDSN(RTDSN) ")

if rtrc = 0 then
 do
   say ""
   say "Return Code from Dynamic Allocation:" rtrc
   say "Absolute Generation Dataset:" RTDSN
 end
else
 do
   say ""
   say "Error in allocating GDG, Dynamic allocation Return Code:" rtrc
 end

exit rtrc

Use the following JCL example:

//* 
//* executes absolgdg rexx to determine the absolute generation
//*
//*  %absolgdg gdgb(SYSGM.CA.OPSMVS.DATASET.BACKUP)
//*  %absolgdg gdgb(SYSGM.CA.OPSMVS.DATASET.BACKUP) gen(-2)

//SYSTSPRT  DD SYSOUT=(,)
//SYSTSIN   DD *
 %absolgdg gdgb(SYSGM.CA.OPSMVS.DATASET.BACKUP)
 %absolgdg gdgb(SYSGM.CA.OPSMVS.DATASET.BACKUP) gen(-2)

Take some (any) big C or COBOL program and run it through the relevant
compiler with the pseudo-assembler output option turned on, OPT and ARCH(9
or 10). Then do an ISPF FIND for the op code. No guarantees of course.

John, here is a REXX Function that will do what you want.  It uses LISTCAT and 
is based on another function that I wrote that also retrieves some other 
information on the specified GDG Data Set.  Since you were only interested in 
the Absolute GDG Data Set  Name, I removed the other code and simplified the 
function.  Enjoy!

/* Returns:  Return Code 0 followed by GDG Data Set Name with the */

Thanks for pointing that out, Kirk. I'm passing this along to our

point to a library PDF from anywhere, try linking to either of these 
types of pages instead:
- KC landing page of the containing element, for example 
https://www.ibm.com/support/knowledgecenter/SSLTBW_2.4.0/com.ibm.zos.v2r4.e0z/e0z.htm 
, which directly links to all the PDF files in that element.

Browsers seem to work, but url links in PDFs from two PDF viewers that I
tried are completely broken.  This makes it impossible to have, say, a

Hi Kirk,

Yes, the URLs are all unique to the release for many reasons that
currently trump the convenience of having release-agnostic "latest"
URLs. Things always change, so I can't say that it will be like that
forever, but it's how the library is structured for now.

In case it helps, this URL doesn't change from release to release - it's
our z/OS Internet Library page of links to everything, and it's the
first URL that I tell everybody to bookmark:

Thanks Susan,

I have a question:  the URL references to the PDFs look like they *might*
be specific to the update/revision.
For example:


https://www-01.ibm.com/servers/resourcelink/svc00100.nsf/pages/zOSV2R4sc276806/$file/foto100_v2r4.pdf


Is there a stable URL to the "latest" V2R4 pub edition for a given

manual?


Perhaps asking about stable URLs isn't something that IBM wants to

discuss

One important item of note is that the revision markers are not showing
up in the Knowledge Center content (for both V2R4 and V2R3). We are
actively working the issue with the appropriate teams and hope to have
it resolved quickly. In the meantime, see the "Summary of Changes"

Okay, please point me to such a PDF as an example if you come across

Is there a published Content-type for .pdx?

Is that index.pdx accessible via HTTP, or only by extraction from the .zip?
If the former, what does IBM's HTTPD supply as Content-type?

The trend among browsers is to become increasingly dumb about MIME
headers and to rely more on filename extensions or even guessing from
content.

I just submitted this RFE this morning that will address this issue (if/when):

Note that there is another RFE for a LISTDSI enhancement for which the

LISTDSI and if the code is open why not do multiple RFE's 😊

If you're inclined to go that way, among my favorites would be:
o Liberate LISTDSI from TSO so it could be used alike from IRXJCL and OMVS Rexx.
o Support LISTDSI( ... FILE ... ) for uncatalogued data sets, even allocated 
zFS files.
  Of course many results would be "N/A", but some could be fetched from

Sounds like another good RFE - go for it.

I think getting the current LISTDSI updated/enhanced will probably be easier 
than that major enhancement but I could be wrong.

...
The "Link" field is extraneous; it just wastes screen space.  Better
to eliminate it and make one of the other fields ("Title" is best) an 
active relative URL to the document.

It's unclear what "Download" is good for.  I can copy it into a browser search
window and Google finds me the document at IBM.com.  Kinda roundabout.

The "Link" is too far from the Title.  On some documents, to be sure I click the
correct link I must use the edge of a window as a straightedge.  A good design
principle is to place the column with the most variable length rightmost, 
regardless
of its importance.

So:
z/OS UNIX System Services

Why, imaginably, would I want to use Linkedin for something like this? Why
not just post the info to IBM-MAIN? Linkedin is for job hunters, not for

Are the tools to set up and administer z/OS systems as easy to use as
those available for setting up and administering Linux systems? Unix
system? Windows systems?  Is an Apache server running on a z series
mainframe any more secure than one running on Linux?  To the extent
Mainframes are available from other vendors such as Unisys, how does
their security compare?  Is z/TPF as secure as z/OS? How about z/VM
and z/VSE?
