Heartland Payment Systems: Largest Data Breach in History?
There's a disturbing story about another data security breach, this one at Heartland Payment Systems, the #6 card processor in the United States. Here's the Washington Post's story: http://voices.washingtonpost.com/securityfix/2009/01/payment_processor_breach_may_b.html AP, Reuters, and all the other major news outlets are carrying the story, too. It appears this breach is the largest ever reported. Full details on the incident are not yet available, but it appears to be yet another case of malware insertion into one or more Microsoft Windows servers, server(s) involved in credit and debit card processing. Heartland acknowledges they only found out about the breach until well after the fact, and only from Visa and Mastercard which both spotted suspicious transactions. (Heartland claims the breach only compromised credit card numbers and names, but that doesn't fully square with the fact there are suspicious transactions. Hopefully we'll learn more.) Heartland has set up a Web site with information concerning the breach: http://www.2008breach.com but apparently they don't have sufficiently scalable Web architecture -- I haven't been able to get through to that Web site for several hours. Their main company Web site (Windows-based, according to netcraft.com) is also impossible to access at present. Heartland filed an 8-K with the Securities and Exchange Commission concerning this incident. The general profile of this incident is eerily similar to the Cardsystems incident in 2005, only bigger. It's probably worth mentioning (again) the IT industry's unique system integrity statement, available exclusively with z/OS: http://www-03.ibm.com/servers/eserver/zseries/zos/racf/zos_integrity_statement.html - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Based in Tokyo, Serving IBM Japan / Asia-Pacific E-Mail: timothy.sipp...@us.ibm.com -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Re: MODIFY VTAMOPTS,TCPNAME=
Luke Ah! Self-imposed FUD! Since I saw this only because I review archives, I didn't respond immediately. If I had I would have asked why you wanted to bother changing the TCPNAME parameter to unspecified, i.e. *BLANKS* as unspecified is presented in the DISPLAY VTAMOPTS messages. Although, as Pat pointed out, VTAM bends over backwards - possibly only from V1R8 since there are massive additional notes following the TCPNAME start option description in the Resource Definition Reference manual of this release with revision bars - in order to pick up the slightest hint as to where to find an Enterprise Extender static VIPA, the clearest way to define the interaction between the two sides of the Communications Server (CS) product, SNA (VTAM) and IP, on the VTAM side for Enterprise Extender support is as follows: 1. Specify the CS IP instance address space name with the TCPNAME start option, a mandatory step if you have a CINET environment even if you are running only one such address space at the time you try to activate the Enterprise Extender lines[1]. 2. Specify either the IPADDR or HOSTNAME operand on the XCA major node GROUP statement in order to identify the local static VIPA supported by the CS IP address space identified in the TCPNAME start option. The TCPNAME start option has no other purpose in life and so there is no harm in having it specified, correctly if you really need Enterprise Extender or whatever you like - excluding not being specified at all it would appear - if you are not proposing to use Enterprise Extender. Note that Enterprise Extender definitions have evolved over the years/MVS releases, and what I propose is not the only way to define those operands/start options but it is the best practice today - and, with any luck, will stay best practice. One - perhaps optimistic - way to approach the matter is to regard the fact the VTAM developers have not bothered to allow you to blank out the TCPNAME start option as indeed confirmation that a bogus, as Pat put it, name cannot do any harm - assuming, of course, you don't actually need to run Enterprise Extender. [1] Where I work from time to time, today included as it happens, I tried to introduce Enterprise Extender support *without* specifying the TCPNAME operand. My understanding at the time was that, if there was only one CS IP address space running, it would be selected automatically. Wrong! VTAM is not clever enough to be quite so flexible! The idea that the TCPNAME operand might not need to be specified was taken from my notes on the topic which were composed back in 2001 and which - I am obliged to believe! - was true at the time, probably at the OS/390 V2R10 level of Communications Server.

One of these, but any one of them, is required if your Enterprise Extender XCA def does not specify an IP addr or host name of its source VIPA. None of them is required if your EE XCA defs specify IPADDR or HOSTNAME. Given that, I'm not sure what you are trying to accomplish by setting the TCPNAME back to blanks.Are you trying to make sure that any EE XCA def without HOSTNAME or IPADDR fails?

Re: SMS and System Temporary Datasets
Bob, IMO going back and updating JCL seems like a lot of work. As Ted says, the ISV products are designed to work with SMS and non-SMS data sets. These X37 and allocation ISV products were around long before DFSMS and are pretty good at what they do. As I stated already, many of the recovery actions that these products perform are actually more efficient than DFSMS. What happens in the future after you have removed VAM when the application grows and your JCL changes are no longer adequate enough; BAM! JCL, X37 abend. This condition would be true for other permanent data sets as well. I've been using the StopX37/EasyPOOL product since I got into IT back in 1989 and could not do without it (I installed DFSMS in 1991). I let DFSMS do it's thing where appropriate, and StopX37/II where appropriate. Plus StopX37/II does work that DFSMS does not perform.

We are hoping to be able to eliminate VAM from the mix. My intent with the extent problem is to identify which dsns are being twiddled by VAM and (for System Temporary dsns) update the space allocation in the JCL. For permanent dsns being change by VAM, I can either change the JCL to specify data class, or let SMS just add additional volumes. Thanks for the reply!

Re: Unix File names EKM and dates
Sorry, I mean that in the properties file I coded Audit.metadata.file.size = 8192 (8MB). At which time it will roll over to a new filename and start over. The only downfall of the current setup is that when the rollover file reaches max size, it reverts back to the original. Too bad they didn't set this up to just rename with a date, and start fresh. Regarding your observations about one home per instance, that is correct, there is not much to share that is not updated. One thing we did that is different than documented, is that we put up another separate copy of JAVA. Since EKM code is delivered with JAVA, in the JAVA filesystem, we wanted additional stability of only updating EKM when we chose too, and not when another PTF reloaded JAVA. Between that, and the fact that EKM requires customization in the SMPE controlled JAVA filesystem, I didn't want to go mucking about in SMPE controlled area's. So, once *could* mount the EKM instance of JAVA READ only or Shared, and then have a separate home for the configuration, and logs. Regarding your comments about no need for one config file per ekm instance that is incorrect, *assuming* you have more than one EKM server for redundancy purposes. There are settings in the config file that define how each instance talks to the other via tcpip.

Re: SMS and System Temporary Datasets
Bob, Using Dynamic Volume Count in the DFSMS Dataclas is terribly inefficient. The Dynamic Volume Count is used to determine the size of the TIOT, TCTTIOT, and JFCB control blocks when allocating a data set. What this means is that with a DVC of 58, every data set using this data class is using 2052 bytes of unused storage (57 x 36 bytes) regardless of the actual number of logical volumes used. This may not be an issue depending on your processor hardware, but it does add up as this storage is never released until the data set is deleted from the system. The StopX37 product does not use allocate storage in the same fashion as DFSMS, so the process is more efficient from a storage standpoint. If cost is an issue, I would consider looking at other ISV options.

We have Implemented Shared HFS in Our Sysplex with 4 Members ,
a few months ago.
Now, we want to upgrade the SYSTEM of 1 of the 4 members of

system , but leaving the 3 other members in the old state.
As reccomended in UNIX System Services Planning in Chapter :
7.6.2 Adding a system-specific or version root file system to your shared file
system configuration
we added the new ROOT as a new Version to the file system .
This new root will be the default root for the upgraded system after IPL .
The problem is that File Systems mounted currently with their Mountpoint on
the Old Root , prevent these File Systems to mount their Mountpoint on the
New Root for the Upgraded SYSTEM.
In this situation we cannot run the Applications running these File systems
on the Upgraded member of the SYSPLEX
Does anyone know a solution for this problem ?
Yes. Nothing should be mounted off of you version root that is not part
of the OS. There are 2 scenarios.
For things you share you mount a directory file system off of your
sysplex root (for shared file systems) and then mount other file
systems off of that one. There is no requirement for the directory
file system, but I've seen a shop's sysplex root grow because all of
the directories / mount points were getting created within the sysplex
root. This eventually led to a sysplex wide IPL in order to re-create
a larger sysplex root. Oh... make sure you are using a single
BPXPRMxx member if not already and pay attention to AUTOMOVE /
UNMOUNT in your MOUNT defintions.
In the case of something that is in the root that you don't share,
you do the same sort of thing with symbolic links that is documented
for setting up CRON with a read only root (see Unix System Services
Planning). This needs to be done each time you do an OS
upgrade (have a new root distributed with ServerPac).
For example, lets say each system has some unique file system
needed to be mounted at /usr/local (which is in the OS / version root).
1) Create /etc/local (/etc is chosen because it is already a system
specific file system)
2) Create a symbolic link for /usr/local that points to /etc/local
.. so if your maintenance OS / version root is mounted
at /service
rm -fr /service/usr/local
ln -s /etc/local /service/usr/local
3) You need to IPL with the new root that has the symbolic LINK
Mount your file system at MOUNTPOINT('/SYSNAME./etc/local')
and use the UNMOUNT parm.
Hope this helps.

This may not be an issue depending on your processor hardware, but it does add up as this storage is never released until the data set is deleted from the system. The StopX37 product does not use allocate storage in the same fashion as DFSMS, so the process is more efficient from a storage standpoint.

What is Bit 4 in 0(R4)?
For reasons that are somewhat complicated to explain I am looking at the code that is executed in IGZCPAC after you return from a module called by a dynamic COBOL CALL.

This is the code path: 067C 5850D004 L R5,4(,R13) R5 @ previous Save Area 0680 50F05010 STR15,16(,R5) Store returncode in previous Save Area 0680 47F0B36A B @071A 071A 91084000 TMX'08',0(R4) Test bit 4 in ? ==??? 071E 47E0B396 BZ@0746Branch if bit 4 in ? is zero? ==??? 0722 95069050 CLI X'06',80(R9) TGT LEVEL INDICATOR = x'06'? 0726 4740B396 BL@0746Branch if level x'06' 072A 1F77 SRL R7,R7R7 = 0 072C 50705018 STR7,24(,R5) Clear R1 in previous Save Area 0730 47F0B396 B @0746 0746 58D0D004 L R13,4(,R13) R13 @ previous Save Area 074A 98ECD00C LMR14,R12,12(,R13) Restore R14,R15,R0,R1...R12 074E 0B0E BSM ,R14 Return to caller The returncode in R15 is stored in the save area so it is returned again in R15 to the calling COBOL module.

SMP/E 3.5 Message Severity Downgrade For Bypass(Holdsys)
I am currently installing SMP/E 3.5 and have noted the downgrade of BYPASS(HOLDSYS) messages from Warning (RC=4) to Informational (RC=0). SMP/E 3.4 behaviour (i.e. RC=4) can be re-instated by using the COMPAT(WARNBYPASS) parameter on the EXEC statement for GIMSMP. As an organisation, we would like to retain the SMP/E 3.4 behaviour for these messages to ensure that the installer has seen the error. Therefore, I would like to implement COMPAT(WARNBYPASS) as a system wide default rather than have each piece of JCL amended. I have reviewed the manual and I cannot find anything in this area.

You can still look at the output and verify what was bypassed. If you are worried that people won't look at the output because of RC=0, then I respectfully submit that those are the same people that routinely ignore RC=4 without looking at the output closely prior to SMP/E 3.5 anyway because they knew (or at least they thought they knew) why they were getting RC=4. Now if I see an RC=4, I know there is something to be concerned about other than the same holds were bypassed for just about every SMP/E apply that I run (certainly for IBM OS maintenance). I think it's best to just document the change to all of the technical groups that use SMP/E and let them decide. At least that is what I did.

Re: Multiple FTP servers?
Dancing with that same bear myself. That's why I was picking your brain. Sorry to interrupt your query. Some thoughts: FTP is considered a security risk and perhaps rightfully so. Most other platforms lack the tools and quality of security we enjoy. FTP has a lot of features and facilities to help with data movement. Among those are the ability to issue system commands (CD, MKDIR, DIR, delete, etc). They aren’t kidding when they call them 'open' systems. IMHO, TLS does nothing to mitigate -that- risk. Sometimes hard to tell what an auditor is really squawking about, but fussing about port 21 would seem to fall into that bucket. Data (to include passwords) flowing over a network in the open is also a security risk, but it's not the same. TLS can help here, but some argue only if fully implemented to include specific certificates for both sides. I donno*. What is important is that one cannot force a customer to do anything other than to take their business elsewhere. Again, all my $0.02 (before taxes) *To my non English speaking friends: 'donno' is slang for don't know or don’t understand or I just work here. -Original Message- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Bri P Sent: Wednesday, January 21, 2009 9:55 AM To: IBM-MAIN@bama.ua.edu Subject: Re: Multiple FTP servers?

Re: Cost of SAS
Well, maybe for some folks, not for others.

That was no help for my shop. Has SAS changed their stance since 2006? January 2006 was when we did it.

I heard at SHARE (and I can't remember the session where I heard it) that, even when the machine is software capped, WLM will continue to manage your workloads based on your goals. At our shop, we have a single production CICS region and were managing it with a velocity goal. When we became capped, the response time in our region would suffer, but since WLM was reporting that we were meeting our goal, it continued until we were uncapped.

Re: No SMF 74(4)
Having stated that 74(4) is required for *all* LPARs, I need to back peddle a bit. As I understand the process, 74(4) is needed to establish the 'qualifying sysplex function' in terms of usage of the relevant structure. For example, if you claim GRS star as the qualifying function, then you need 74(4) to show that all purported sysplex members do indeed use ISGLOCK. If you have other nonmember LPARs running on any of the CECs in the mix--either monoplex members or members of a different sysplex--then it's not clear to me why you would need 74(4) records from the noncandidate LPARs. If an LPAR is not offered up for verification, then who cares what structures if any it uses? On the other hand, gathering 74(4) from *all* LPARs may in the end be easier than getting someone to sign off with data gathered selectively. I took the easy way out and submitted data from all LPARs. Such a wuss. . .

Re: Cost of SAS
No longer required to be a standalone CPU. SAS will negotiate for a capped LPAR. It's not truly a negotiation. SAS Institute told us what their policy was. We told them the LPAR weight, where SAS was running, was 35% of the physical capacity. They charged us a C licence (110-150 MIPS), instead of an F (400-450). I understand that it took some time to educate the SAS Institute marketing staff on what an LPAR represents, in early 2006, when the program started. SAS Institute wasn't the problem/issue. Our service provider's licensing staff couldn't understand that sub-capacity was in effect for the licence, and wanted us to pay the class F rate. That took more effort than SAS Institute invested. It was a phone call and a FAX from them.

The keys on a track were always in order so that a search key GE CCW would read the correct record from the track. I also remember that the key for the GVnn portion of the node was reversed by doing an XC with 8X'FF' so that the largest goovoo number would be at the beginning of the record, thus easier to find. I.e. to find the current goovoo, the search ke GE would simply be 8X'00'. That's what I remember.

What I remember, and perhaps you can correct me, is that a CVOL was much like a PDS directory. Yes. The data portion of a record was 256 bytes in length. And it had an 8 byte hardware key. The key on the record was the highest value of the node within the record. Correct The keys on a track were always in order so that a search key GE CCW would read the correct record from the track. Yes. I also remember that the key for the GVnn portion of the node was reversed by doing an XC with 8X'FF' so that the largest goovoo number would be at the beginning of the record, thus easier to find. I.e. to find the current goovoo, the search ke GE would simply be 8X'00'. Yes, or just read the first record. Perhaps J R is correct and it was done this way to be able to more efficiently retrieve the current entry. I was thinking of a performance benefit in updating the catalog or in reading the entire group. Now that I think of it, it would be a lot easier to find an older generation too. That's what I remember. But I've been getting ECC errors on my memory for a while now. Lucky you. You have ECC memory.

IBM Tivoli Tape Optimizer on z/OS
I am running an IBM VTS-B18 and installed an IBM VTS-B20 with the intent of moving all the files over from the B18 to the newer B20. HSM files are easy to do as I have cut off allocation to the old and only into the new. Then along with recycles, it will all go over. Once the B18 is empty it can be offered to the Smithsonian along with its 3590 drives. Looked around at products like OpenTech's and CA's tapecopy offering and even though they seem to be first class products, the cost is also first-class (in the old days it would more than Air-Mail). I ran across this Tivoli utility for what I am told is $5K per z9BC. Does any one have any experience with the product where it copies files with not much up front work coding JCL, and then does all the adjustments with the Catalog and in my case, RMM.

Re: Opinions on next version of TXT2PDF
Leland very kindly gave me an early copy of a version of TXT2PDF which includes TrueType font support. For my use, I found that output looks much better with TrueType than with the default Courier font. A specific example I use is to create a report from HCD for my entire z/OS gen. One complaint I've always had was that the letter O and the zero were difficult to distinguish. Now, with TrueType support, I can pick a font I like better. Here's what I did - with all credit to Leland for showing me how to do this. After Leland showed me how, I tried each of these steps again myself just to make sure I understood what to do. 1) Find a good font. Many are out there under generous open source terms. An example I'm using now to replace Courier is Bitstream Vera Sans Mono, which has generous open source terms: http://www.bitstream.com/font_rendering/products/dev_fonts/vera.html 2) Upload the font to a z/OS data set 'hlq.VERAMONO.TTF' - use binary, LRECL=27994, BLKSIZE=27998, RECFM=VB. 3) Use the new version of TXT2PDF and add the following keywords (XFONT is the new keyword where TrueType support is added): IN 'hlq.REPORT.LIST' + OUT 'hlq.REPORT.PDF' + XFONT TT/VERAMONO//'hlq.VERAMONO.TTF' + FONT 6/VERAMONO/100 + COMPRESS 9 + CONFIRM YES + LPI 12 + TM 0.2 BM 0 LM 0.75 RM 0 + ORIENT PORTRAIT + IFEMPTY BLANK In my application, I am trying to format my HCD report as 132 colums, 125 lines per page, with portrait orientation. Using Courier, the small six point font is unreadable when printed. Using this TrueType font, it's very readable. I would encourage anyone who's interested in this major (my opinion) enhancement to TXT2PDF to send Leland an email request for a copy of the new version. I'm very impressed with this update!

Re: Cost of SAS
From what I understand, that is no longer the case. Barry supports running MXG under WPS. His support is that if you get an error while running under WPS, then send the data to him, and he'll run it under SAS. If it fails under SAS he'll accept the error and fix it. If it runs under SAS then you'll need to contact WPS for a fix. He has also made some changes to MXG so it will run under WPS such as a special AUTOEXEC for WPS. However, there are some things outside of MXG itself to watch out for with WPS. For example, I create PDF format reports using ODS and use PROC REPORT extensively.

Recently, I ran a zSecure Audit MVS Tables status scan and one of its findings was the following: Instruction scan hit, Updated using SVCUPDTE, Installation-defined SVCno, Caller may be unauthorized Pri SVC ES# APF Function Appl U Sf Last update From Where 24 255 No1 A1 0009D1B0 PVT Index Address Where Key SP ScanIns Length AM Entry at Same addr as Eye catchers CN04FE1DB8 EPLPAM 584 31 EJESSVC .EJESSVC ..092720071430LICENSED MATERIAL, PROPERTY OF PHOENIX SOFTWARE INTERNATIONAL -- COPYRIGHT (C) 1990-2007..kx4..

Re: zSecure Audit Concern with EJES SVC
Ed will likely need to reply. However, it could be simply that the zSecure Audit function is simply not aware of what the EJES SVC does and so flags it. There is an SVC in CICS which could be considered problematic if one did not know how it worked internally to ensure that it is not called improperly. -- John -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Re: MVS 4 minute 'outage' (final update)
IBM DB2 support determined the 'hang' problem was caused by a DB2 application program. Without getting into details, DB2 does a 'suspend for commit' that can take 7+ CPU minutes to complete. DB2 support suggests we fix our application (which I agree we should). However, it seems like the DB2 code should not be able to cause a 7+ minute MVS 'outage'. Am I wrong to think the DB2 code should be fixed too? -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Problem using CSI profile to order maint
I created a new CSI profile to order a PSP bucket from upgrade ZOSV1R9 subset BCP. However I only received 1 PTF when I downloaded. When I view the order number on PSP I see lots of PTF's that I do not have in receive status, yet they were not on my download list to be received. Can anyone shed some light on what I am doing wrong? John Norgauer University of California Davis Medical Center 2315 Stockton Blvd ASB 1300 Sacramento, Ca 95817 916-734-0536 SYSTEMS PROGRAMMING..

Re: Amid Economic Turbulence, Mainframes Counter IT Cost-Cutting Trend
Hi, Your first article was created by KPMG , an audit, tax and advisory firm in the USA.. that we all can trust, such as ACCENTURE... registered in BERMUDA so that they pay no taxes in the USA legally. Sounds like what we heard for 8 years : Cut Taxes for Corporates and spend more because who cares about deficits.. Hopefully Obama will address this issue soon and black-list all these companies that pay no taxes but then they might register as a Bank, and claim Bail out money and a huge annual performance bonus for their efforts.

Re: MVS 4 minute 'outage' (final update)
Not clear what is broken. The app was exploiting DB2 services in a manner that did not suit you, but maybe there was a compelling business need to do just that. I can recall an app that would bring the whole world to a screeching halt every time it ran. Management was pleased that the app got every cycle it could and took the complaints as evidence of goodness.
