Re: partially initialized structures in C (3)
To David:
no, there is no MVC. This is the z/OS V1.6 C-Compiler.
I will try and examine the newer versions. Maybe the error is only in this
version. But the description in the language reference also tells that the
remaining components remain uninitialized, which is very strange.
We, too, do this initialization all the time. That's why we feel in
trouble now.
Most of the time, the areas are explicitly initalized later, anyway, so
there is no problem.
But in this case, it is not. But still, most of the time, the area is
zero, because it has not
been used before. So there is still no problem. We observed this problem
in the last week
for the first time and it took us several hours to find the reason for it.
To Charles:
The next component is not char, so it makes no sense to simply put
a single hex zero in front of it. The only good reason for the MVI would be
if a overlapped MVC would follow.
Kind regards

To make it clear:
see above
The ST operations initialize the first components of the structures,
which are fullwords. This is what should be done, according to
the IBM C language reference.
The rest of the structures should remain unchanged (uninitialized),
according to IBM's language reference, and should be set to zero,
according to ANSI C language reference. The structure out1215,
for example, is 24 bytes long.
Now the MVI makes absolutely no sense to me.
It would only make some sense, if it was followed by an overlapped MVC
instruction, which would set the rest of the structure to zero. But
such a
instruction is not generated by the compiler.

Hello all,
sorry for asking this question on IBM-Main, but the C370 list is so
silent
that I doubt that anyone is actually listening.
We observed a sort of problem today which showed up as a 0C4 abend
due to a not proper initialized pointer component of a C structure.
Further examination showed that the structured was initialized as
follows
structure_type structure_identified = { 0 };
The structure has several components; the last component is the
pointer.
According to the IBM C language reference, only the first component is
initialized to zero, and the other components have random contents,
because the storage class is automatic. The compiler generates only
initialization logic for the first few bytes of the auto structure.
So from this
point of view, everything is right.
But: the ANSI C language reference, for example in the Kernighan
Ritchie
book appendix, and most other C language references I found on the
web,
clearly state that if the number of initializers on structure
initialization is less
than the number of structure components, the remaining components are
initialized to zero, even for auto structures.
This is not an error in that sense that the compiler does not what
is written
in the language reference, but instead it is a contradiction
between IBM's
language reference and ANSI language reference.
What do you think about this? Does it make sense to complain at IBM
about it? We have hundreds of C programs in production use which use
this kind of initialization (maybe) and now we are afraid that we
need to
examine all these programs.
Kind regards

Re: partially initialized structures in C (3)
Bernd,
I'm using z/OS V1.10 without INITAUTO. We've compiled our code all the
way back to OS/390 2.8 and I can't recall ever seeing
this problem. I'm sure it's a codegen bug, otherwise what is the point
of the MVI?
I wouldn't accept anything other than a fix from IBM. Although your
compiler is out of support!
Quote 6.7.8.21 of the ANSI C standard which clearly states:
If there are fewer initializers in a brace-enclosed list than there are
elements or members
of an aggregate, or fewer characters in a string literal used to
initialize an array of known
size than there are elements in the array, the remainder of the
aggregate shall be
initialized implicitly the same as objects that have static storage
duration.

Re: partially initialized structures in C - solved
Hello David and all others, I have to apologize. The MVC instructions which initialize the rest of the structure come very late, some 40 instructions later, after the function prologue, so I didn't realize them. But in fact, you are right, David, they are there, and the structure is initialized up to the end. So the only thing I have to blame IBM for is that the description in the language reference does not reflect the correct ANSI behaviour, which lead us to all this mess. I would kindly ask IBM to change the description in a way to be compatible to the ANSI standard and to that what the compilers, in fact, do. Sorry about that. The 0C4 abend had another reason.

Re: Stubborn OSA Express-3 ?
Walter I always wondered why the manual bothered mentioning the famous downloading of IP addresses in the preamble to the section on Querying and Purging the ARP Cache - and now - I guess - I know! You need to keep in mind that OSA logic is playing fast and loose with ARP entries as IP addresses fly around in your Communications Server IP component. The conclusion would appear to be to purge the ARP cache when you are reconfiguring the IP address environment of your LAN - which actually sounds eminently sensible whatever tricks may be happening under the covers! So that's purge the ARP cache rather than shut down LPARS - should be a bit easier and, well, a bit less disruptive! Chris Mason [1] Open Systems Adapter-Express Customers Guide and Reference, Chapter 9, OSA Port Management: quote Querying and Purging the ARP Cache The Address Resolution Protocol (ARP) cache resides on the OSA-Express feature. When TCP/IP is started in QDIO mode, it downloads all the home IP addresses in the stack and stores them in the ARP cache. When running OSA- Express features in QDIO mode in a z/OS V1R4, z/VM Version 4 Release 4, or Linux environment, you can query and purge the contents of the ARP cache. Communications Server for z/OS V1R4 adds support for querying and purging the ARP cache using the following commands: To purge the ARP cache on z/OS VARY TCPIP,,PURGEcache,linkname for example, v tcpip,,purgec,link4 To query the ARP cache on z/OS DISPLAY TCPIP,,NETSTAT,ARP,ip_addr for example, d tcpip,,net,arp,10.11.91.200 or TSO NETSTAT command, for example, netstat arp all tcp tcpip To query the ARP cache on z/VM NETSTAT command, for example, netstat arp * See z/VM TCPIP Users Guide. The Linux qetharp utility is available to query or purge the contents of the ARP cache, for example: qetharp -q eth0 shows all ARP entries for OSA-Express interface eth0, while qetharp -p eth0 removes all entries from the ARP cache for OSA-Express port eth0. See Linux for zSeries: Device Drivers and Installation Commands, LNUX-1103, for a complete description of this command. /quote On Wed, 19 May 2010 02:58:12 -0700, Walter Marguccio walter_marguc...@yahoo.com wrote: yes, we got: EZZ4329I LINK OSA Look for messages like: yes, we got: EZZ4329I LINK OSAEGFCLNK HAS TAKEN OVER ARP RESPONSIBILITY FOR INACTIVE LINK OSAEGF8LNK at the time we moved the cables. after all 6 cables were connected to the new, single switch (I know, this is a SPoF), the only OSAs we were able to ping/telnet were the OSC CHPID-type (OSA- Express2) for our MCS consoles and non-SNA TSO sessions.

Re: IBM to announce new MF's this year
I thought that IBM has a line of 'massive parallel' systems. Wasn't the Deep Blue chess machine a working prototype? According to a press release, NNSA has selected Lawrence Livermore National Laboratory for the development of two new IBM supercomputing systems, Sequoia and Dawn. Sequoia will include 1.6 million IBM Power processors housed in 96 racks the size of refrigerators, and occupy 3,422 square feet. It will be a 20 petaflop per second system based on future BlueGene technology to be delivered in 2011 and deployed in 2012. It also will have 1.6 petabytes of memory and 96,304 compute nodes. http://www.crn.com/hardware/213000491 dated 2/3/2009 Does this qualify for a 'single system image'? Also, if we loosen our definition of 'cores' from just the central brain, we find processors all over the typical z/box. While a program instruction step may be carried out in only one of a couple of 'engines', there are many others assisting in accomplsishing the mission given by the instruction step. As to The Register's statement, one has to wonder how El Reg defines 'mainframe'. Perhaps it is not liminted to z/stuff. -Original Message- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Shane Ginnane Sent: Wednesday, May 19, 2010 8:17 AM To: IBM-MAIN@bama.ua.edu Subject: Re: IBM to announce new MF's this year I remember much levity in my time at Amdahl and IBM's inability to build a machine that scaled past 10 (?) engines.

Re: partially initialized structures in C
Bernd,
That sounds like a compiler bug, but more detail would
be needed to be sure.
The ANSI C standard basically works like this:
A structure initialized a file scope (static or not) will be
initialized to all zeros.
If the structure is being initialized within a function
(at automatic scope) then the requirement is that it be
initialized the same as if it were done at file scope,
which basically means if you initialize part of it, you
have to initialize the holes with 0.
I'm surprise the IBM documentation would indicate
that a partial aggregate initialization only partially
initializes - can you point me to the pertinent
phrases in the IBM doc? The requirement to initialize
the remainder of the aggregate with zeros has been
around since the very first ANSI C standard.

The ST operations initialize the first components of the structures,

Now the MVI makes absolutely no sense to me.
It would only make some sense, if it was followed by an overlapped MVC

such a

We use the z/OS v1.6 version, and this version only generates the MVI, not the MVCs. We will not use INITAUTO due to serious performance degradation. At the moment, management discusses the strategy to follow: a) opening a PMR with IBM, and, if IBM agrees and changes their compilers, recompiling all our C programs b) accepting the behaviour of the IBM C compilers and examining all our sources, changing all partial structure initializations to memset and, again, recompiling all our C programs I'm pretty confident the IBM compiler follows the ANSI C standard and that some other reason is the cause of the confusion. If you discover it doesn't, and it's a problem; might I humbly offer our alternative (which can operate in your LE environment.) We definately would initialize that structure to all zeros.

Make DASD index larger.
All, What is the best way to enlarge a DASD - INDEX on a volume? I have a 3390-9 volume with a 900 track VTOC and a 30 track index. The VTOC is okay, but the index is full, getting full. If I extend the VTOC and rebuild the index, that does not gain any index space, just re-orgs it right? I have moved/enlarged VTOC's before but not the index. There is this parm I tried on a new volume, 'REFORMAT REFVTOC', but can't find much doc on it. The volume(s) are not SMS managed, but belong to DFHSM as migration level 1 volume(s). Any ideas?

Re: Make DASD index larger.
Claude, I recommend: 1) Use DSF BUILDIX OSVTOC 2) Delete the VTOCIX from the volume 3) Use DSF BUILDIX IXVTOC as follows This option requires additional parameters on the DD statement to cause allocation of the index. The statement must contain data set information for the index. //jobname JOB //stepname EXEC PGM=ICKDSF //SYSPRINT DD SYSOUT=A //VOLDD DD UNIT=(3390,,DEFER),VOL=(PRIVATE,SER=339003), // DSN=SYS1.VTOCIX.V39003,DISP=(NEW,KEEP), // SPACE=(TRK,10,,CONTIG) //SYSIN DD * BUILDIX DDNAME(VOLDD) IXVTOC /* DSN=SYS1.VTOCIX.V39003 specifies the name of the index data set. Because the INDEX parameter of INIT replaces the first character of the volume serial number with the letter V, the third-level qualifier appears as V39003. The recommended convention for naming the index is using the letter V as the first character, for example VL3390. For more information, see Converting an OSVTOC to an indexed VTOC on page 118. DISP=(NEW,KEEP) directs the system allocation routines to allocate the data set before running ICKDSF commands and to retain it upon termination of the task. SPACE=(TRK,10,,CONTIG) when location is not a primary concern, reserves ten contiguous tracks at some location. If you are processing system-managed volumes, you cannot specify ABSTR on the SPACE parameter. SPACE=(ABSTR,(10,1)) directs the allocation routines to allocate a ten track index starting at track 1. ABSTR is specified in the space request to ensure that the index space is a single continuous extent and is in the location desired.

Re: PSF IBM 6500 printer
The 6500 supports up to a 17-inch wide form (16-inch print width). The number of characters depends on the form size and the font pitch. For example, using a 13.3 pitch font (D224) you can get 212 characters. The 6500 uses symbol sets (hard-wired fonts), so you can use only the fonts in the printer. In Draft or DP quality, fonts are available in pitch 10, 12, 13.3, 15 and 18. You only need PSF Exit 8 if you are using the Line Mode Migration function, which converts FCBs to PAGEDEFs on the fly. Even if you do use Line Mode Migration (PSF Customization, S550-0427-02, Chapter 28. Line-Mode Migration), using a PAGEDEF will override the Line Mode Migration function. Whether or not you use an FCB or a PAGEDEF, you can choose the font using the CHARS parameter in the // OUTPUT JCL statement or on the printer PROC. You must use one of the fonts defined in the printer (see Chapter 19. Supporting Resident Fonts in the PSF Customization book and table 167 in Printer Information, S544-5750-02). If you don't need special formatting, you can use one of the supplied PAGEDEFs (PSF User's Guide, S550- 0435-02, Appendix B. Page Definitions Supplied with PSF). Some fonts depend on the print quality level. You can control the print quality (lower quality, faster printing) using one of the supplied FORMDEFs, detailed in the Line-Mode Migration chapter.

Re: zOS Network Authentication Service (Kerberos)
On Wed, 19 May 2010 12:28:55 -0400, Mark Jacobs mark.jac...@custserv.com wrote: My end desire is for a process running on a Windows based workstation access a SMB share under zOS. As far as I know SMB authenticates one of three ways; 1. Windows/NT Domain controller - Not an option since it's out of our environment, replaced by Active Directory. 2. Racf authentication - There is strong resistance against using a hardcoded userid/password coded in this application so my very early research led me to passtickets. 3. None(Guest Access) - Not acceptable. What I'm looking for is for the process on the workstation (already authenticated by AD) to be accepted by RACF as an authenticated zOS userid without supplying a password. That's what Kerberos allows, Mark, if you have an application that supports the Kerberos protocols. But it's not at all related to PassTickets, which are simply a substitute RACF password, and would work wherever and over whatever protocol supports RACF user IDs and passwords. Kerberos is a separate protocol, with different data flows, and does not directly involve RACF user IDs at all (applications need to map from a Kerberos principal to a RACF user ID), and the authentication mechanisms are different than a simple password, too. Unless SMB says it supports Kerberos (or AD, which is another form of Kerberos implementation), I think you're probably out of luck trying to use Kerberos in this scenario. You might well be able to write your own code (or get someone else's) that will generate a PassTicket, and use that. You'll need to worry about security of the secret key used in the generation process, if you generate it within your application, though. A better alternative would be to connect to the z/OS Comunication Server's DCAS server using SSL- or TLS-based client authentication using a digital certificate, and have DCAS generate and return a PassTicket that your application could then use.

Getting BIND/LINK date out of load module members
I am working on process to monitor/audit load libraries for new/replaced members during a date range. I have a working version that uses AMBLIST with a SYSIN of LISTIDR. I run the REPORT OUTPUT created by this to a disk dataset for a given load library. Then in the next step, I parse the REPORT output looking for the member name and BIND date. If the BIND date is less than 3 days old, I output the member name on the report. The AMBLIST step (unloading all the member data to the report) takes quite awhile for some of our larger LOAD libraries. And of course, outputs a lot more info than I need. I just need the member name and the BIND date. Is there another IBM utility (or a different parameter for AMBLIST) that would unload a LOAD library of its members and dates more efficiently? I only run this once a day, so it is not a big deal that it runs quite a while, but it would help testing new features if I could get the AMBLIST part to run faster. Thanks in advance!

I made a copy of SYS1.CMDLIB and ran PDS85 (the name on my system) in batch to get the following report: NAMEALIASOF CREATED SIZE SSI ATTRIBUTES AKJLKL0110/02/08 17832 01119368 RENT, REUS, REFR ARCBDEL 10/02/08 34016 01118183 RENT, REUS ARCRMDS 10/04/12 176K 0158 RENT, REUS CBRUTIL 10/04/12 12112 01110829 RANY, A31, RENT, REUS, REFR HBACK ARCRMDS 10/04/12 176K 0158 RENT, REUS HBACKDS ARCRMDS 10/04/12 176K 0158 RENT, REUS HBDEL ARCBDEL 10/02/08 34016 01118183 RENT, REUS HBDELETEARCBDEL 10/02/08 34016 01118183 RENT, REUS HDELARCRMDS 10/04/12 176K 0158 RENT, REUS HDELETE ARCRMDS 10/04/12 176K 0158 RENT, REUS HMIGARCRMDS 10/04/12 176K 0158 RENT, REUS HMIGRATEARCRMDS 10/04/12 176K 0158 RENT, REUS HRECA ARCRMDS 10/04/12 176K 0158 RENT, REUS HRECALL ARCRMDS 10/04/12 176K 0158 RENT, REUS HRECOV ARCRMDS 10/04/12 176K 0158 RENT, REUS HRECOVERARCRMDS 10/04/12 176K 0158 RENT, REUS IKJLKL01AKJLKL0110/02/08 17832 01119368 RENT, REUS, REFR OAMUTIL CBRUTIL 10/04/12 12112 01110829 RANY, A31, RENT, REUS, REFR I created the above report using the following JCL: //TSO EXEC PGM=IKJEFT01 //STEPLIB DD DSN=SYS4.PDS.V8R5M0.LOAD,DISP=SHR //SYSPRINT DD SYSOUT=* //SYSTSPRT DD SYSOUT=* //SYSTSIN DD * PDS85 'tsoid.SYS1.CMDLIB' IF : LAST(120) END // For the test above I made a copy of SYS1.CMDLIB in tsoid.SYS1.CMDLIB. This load library had 295 members. The IF : LAST(120) above is telling PDS85 to list out the members (the : says all members in the dataset are included) that were linked over the last 120 days before today (or what ever day it was run). You wanted to run the type of report above going back three days but tsoid.SYS1.CMDLIB did not have any load modules linked over the last 3 days which resulted in the job getting putting out this message 'NO MATCHING ATTRIBUTES WERE FOUND '. That's why I ran it with LAST(120). You should be able to get the product above from web site www.cbttape.org if you don't have it. There are many other keywords for PDS. You could use CHANGED (1/1/10:3/15/10) instead of LAST if you need a range. (Untested) Good Luck.

I have a working version that uses AMBLIST with a SYSIN of LISTIDR. I run the REPORT OUTPUT created by this to a disk dataset for a given load library. Then in the next step, I parse the REPORT output looking for the member name and BIND date. If the BIND date is less than 3 days old, I output the member name on the report. The AMBLIST step (unloading all the member data to the report) takes quite awhile for some of our larger LOAD libraries. And of course, outputs a lot more info than I need. I just need the member name and the BIND date. Is there another IBM utility (or a different parameter for AMBLIST) that would unload a LOAD library of its members and dates more efficiently? I only run this once a day, so it is not a big deal that it runs quite a while, but it would help testing
ZAAPAWMT under Hiperdispatch
In our development environment, we have dozens of Websphere App servers running, and we only have one zAAP (on a z10-704). The aggravation is that we have significant overflow of zAAP eligible workload to GP engines, despite the zAAP being nowhere near 100% busy (whereas all the GPs are 100% busy, pretty much 24x7! with a slight respite at weekends.). With Hiperdispatch off, ZAAPAWMT is 12000, and with it turned on, it gets reduced to 3200 (I think these are standard values, rather than site specific). I am anticipating that increasing the ZAAPAWMT value would help raise the utilisation of the zAAP, thus reducing the impact on the GP engines. Does anyone have any experience of altering the ZAAPAWMT values with Hiperdispatch turned on? Or is conventional wisdom not to mess with the IBM defaults? Would be grateful for any insights/experience anyone may have on this subject.

Re: Of interest to the Independent Contractors on the list
How many of those Prophets of Doom knew what they were talking about but it worked for most executives. The doom would have been real enough if the prophets had been ignored. We began fixing that Y2K thing'gie in late 1992, a tad over 7 years before 2000. At that time it was mandatory in some jurisdictions to keep tax-related business records for seven years. In mid-1992 we recognised that from 1st Jan 1993, when our major product archived files, they would have the YY part of their discard date calculated as 00 (93+7=100 truncated to 00) and thus immediately appear old with the result that they would be deleted within 24 hours of capture! Of course there were other things to be fixed across all our products. I recall that another major effort was required in '97, but essentially, like many, we were done with Y2K before the start of 1998. Countless other professionals did corresponding good work and as a direct consequence Y2K was not a disaster at all. One suspects that sections of the media were hoping it was going to be very bad (planes falling from the sky, toasters electrocuting their owners, elevators plummeting and countless other pieces of mundane equipment going Disney-dancing cranky. And sure, as inevitably happens when there's a must-do-by-a-fixed-date project with an essentially unlimited budget and other boundaries very poorly defined, quite a lot of other stuff got slipped through under the guise of Y2K remediation. Yeah, that's just human nature. So, absent the total murderous malfunctioning of just about every aspect of our technical society, media can still occasionally squeeze a few column-inches out of the great Y2K conspiracy to defraud us all rubbish. Yawn. There's a real story, which media doesn't cover, about how many of the Y2K fixes crafted back in the late '90s were not going to last for more than a few, maybe ten or fifteen years. And I'd guess at least some people decided that this application will be replaced by (cut 'n paste from your favourite airline mag article here) no later than 2010! Uh huh. Toxic residue from Y2K remediation will continue to surface as we plow on into the 21st century. And many of the people who know/knew the details are going/gone. Ok, back to work (got an order for some square pegs). Cheers to all, Graeme At 10:12 AM 17/05/2010, you wrote: This type of article re-appears every two years..
