Re: Which JES2 control block contains the SDSF DSDATE/JOBCRDATE fields?

[Robin Atwood]

You want either the IAZSSST or IAZSSS2 dsects depending if you are going the 
extended status (STAT) or SAPI (SSS2) route. It's not for the faint-hearted but 
the dsects contain much embedded doc.

question about dataspace scope=all and Yes I read extended addressability pages 124 - 129 a few times

[Joseph Reichman]

Hi 

 

If I create a dataspace scope=all in SRB mode my TCBTOEKN points ASCBXTCB do
I have to put on the access list if I wont reference in the address space
that is was created

 

In Addition I am not quite sure ADDPASN does Initially I thought that if I
added the stoken to PASN of that address space that it was created in.

 

I could use that ALET in the address space I would like to reference with
ADDPASN 

 

Still  had problems until ALESERN PASN in the address space it was created
in and ALERSERV in the address space I reference it in with AL=WORKUNIT

 

thanks

Re: Learning shell scripting

[Frank Swarbrick]

I just found this:

https://www.ibm.com/support/knowledgecenter/SSLTBW_2.3.0/com.ibm.zos.v2r3.bpxa400/shs.htm
Writing z/OS shell 
scripts
To simplify such jobs, the shell lets you run a sequence of commands that have 
been stored in a text file. For example, the programmer could store all the 
appropriate compiling and linking commands in a file.

Largely, I glanced at examples and read man pages.  I never went

Re: Value of PSW program MASK in an attached sub-task

[Attila Fogarasi]

LE will do that, based on the language profile of the attached modules (and
ORs the mask bits together if there are multiple languages).  You can call
CEE3SPM to set the program mask yourself.  Even if you think you aren't
using LE, something you call could be creating an LE environment.

Value of PSW program MASK in an attached sub-task

[Thomas David Rivers]

I seem to have a situation where the program mask for my attached
sub-task is getting all the bits set (indicating, for example, the receipt
of, say, FIXED-POINT OVERFLOW) when the parent task does not
have those set.

Does anyone know what determines the setting of the program mask
for the ATTACH'd task?   And/or how to indicate "set the mask to whatever
was true for the parent at the time of the ATTACH".

Trying to track down this mysterious setting of all the mask bits, and
I'm wondering if there is some ATTACH magic I need to be aware of.

Which JES2 control block contains the SDSF DSDATE/JOBCRDATE fields?

[Al Loeffler]

The SDSF H and O panels display a creation date and time for each output DDNAME 
in a job when a '?" is typed in the NP column. The SDSF User's Guide gives the 
column name as DSDATE with a width of 10 and says that the installation can 
change the CRDATE column to 19, so that the date and time is included. There is 
also a column called JOBCRDATE that has a width of 19.

The $PDDB contains a creation time (PDBCRTME), but no creation date (according 
to the JES2 Data Areas manual). I've searched SYS1.SHASMAC and the JES2 Data 
Areas manual for any date fields, but haven't found any.

Does anyone know which JES2 control block contains this information?

Regards,

Al Loeffler

Re: Learning shell scripting

[Demetrios Dimatos]

As you know, USS commands are ported so sometimes they don't correspond to 
their *nix ancestors. So, reference this often:
https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.bpxa500/toc.htm

When I was getting started many yrs ago in kernel development I always enjoyed 
"Unix Power Tools" , there are many versions of it out there, not sure legally 
hosted or not so I will leave those PDFs searches up to you (I still have a 
hard copy of the book).

I do find much overlap with USS and *nix concepts.

https://www.oreilly.com/library/view/unix-power-tools/0596003307/

Along the lines of shell scripting, look into Z Open Automation Utilities to 
enhance your scripts to do even more MVS functions beyond what USS supports.
https://www.ibm.com/support/knowledgecenter/SSKFYE

And if you are like me, you will find shell scripting now replaced with Ansible 
Playbooks (I can do so much more and so much quicker).

Re: JES2 message $HASP375 Estimate exceeded

[Mark Jacobs]

Look at your jes2parm for what the limits are set at. I've seen messages for 
lines exceeded and later KBYTES in the same job log once that limit was 
reached. I assume that pages are specifically meant for fully composed AFP data 
and lines for line mode data.

JES2 message $HASP375 Estimate exceeded

[Jesse 1 Robinson]

We've had some cases of a job taking over the spool. In researching a solution, 
we've noticed that message $HASP375 varies in ways we don't understand. Doc for 
the message looks like this:

>--jobname--ESTIMATE EXCEEDED BY--nnn--+-LINES--+--->
   +-CARDS--+
   +-KBYTES-+
   '-PAGES--'

>--+-+-><
   '-xxx--%SPOOL-'

We don't understand why the overage is sometimes reported as Lines, Cards, 
Kbytes, or Pages. Why does JES2 pick one descriptor or another?
