Re: IBM announces 6% price increase for z/OS
Did your total IBM software bill decline or increase during that period? I didn't get deeply involved in software costs until c. 2008, so it took some digging, but I did find our then current MLC costs c. 2005 when we were on z900s and looking to go to z9s. In short, today, on z10s with vWLC, our monthly MLC cost is about 10% less (in total, all MLC products) than what it was then on the z900s. Now some of that is because we did eliminate a few unused MLC products (such as old compilers) over the past few years, but I believe that those only totalled to something on the order of 2-3% of the monthly cost. If we hadn't done that, and if we were paying full-capacity VWLC, then I believe our cost would be very close to what it was in 2005. But still, no net increase across a 7 year time-period wouldn't be a bad run. Note that I'm not trying to make the case that z/OS and associated products are by any means inexpensive. Nor am I happy about the 6% increase now. Whether the cost is a reasonable value is a much more complicated analysis that is going to be dependent on every organization's particular needs. For some, I'm sure it's not such a good value. Certainly it is a much better value (on a cost/unit of capacity basis) for much larger shops. Oh, and I didn't try to look at zOTC, because that's even more complicated as we've swapped multiple products between IBM and ISVs over that time period as well as eliminated some products.

Re: Going from mod-3 to mod9
Thanks, Ron. I didn't know about the 3990-3's ability to process two cache hits simultaneously. I would assume, though, that both I/Os would have to be read only. And all that the controller has to do to test for read-only is to test two bits in the File Mask byte. The pending time I described existed with the introduction of S/370-X/A in the early 1980s for all attached DASDs, I believe. The single threading with MDA is necessary if there is any possibility that one I/O can alter data that another active I/O to the same logical device might need to read. This is controlled in EMC's 2105 microcode by single-threading all I/Os to device X that have at least one track in common in their defined extent track ranges AND if any of the I/Os with the extent overlap is not read-only. As long as all the I/Os to device X are read-only, then an infinite number of them can run simultaneously with no worries. But as soon as an I/O is found to be non-read-only, then its track range is used for single-threading against all other I/Os running that have at least one track in both I/O's track ranges. E.g., if I/O (1) from system (A) to device X has a track range of -5678000E and is read-only but I/O (2) from system (B) to device X has a track range of 5678000E-5679 and also has the potential to write data somewhere within that range of only two tracks, then both of these I/Os must be single-threaded and executed in the same sequence in which they entered the control unit. At least this is how EMC's patent application describes how their equivalent MDA microcode works. And this single-threading is not forced upon the I/Os by sibling pend but rather is required in order to guarantee data integrity regardless of how many siblings or internal paths there are. Bill Fairchild -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@bama.ua.edu] On Behalf Of Ron Hawkins Sent: Friday, January 27, 2012 9:17 PM To: IBM-MAIN@bama.ua.edu Subject: Re: Going from mod-3 to mod9 Bill, You said If the shared control unit attached to this device is not an IBM 2105 SHARK (vintage ca. 2000), plug-compatible equivalent, or some successor technology, then image A's I/O will not really be started until image B's already started I/O ends. Logical Device allegiance was introduced in the 3990-3 would allow ImageA and ImageB to process two cache hits concurrently providing they were not on the same track. My understanding is that the pending time you described occurs when the both systems tried to access the disk drives in 3990 controller emulation. Multiple Device Allegiance (MDA) was developed to allow concurrent access to multiple disk drives that make up the logical volume. There's no need single threading IO requests from multiple systems when there's four or more disk drives that can handle the IO without sibling pend. HDS had a function called the multi-job IO feature that would allow up to four LPARs to access the HDD for a logical volume concurrently. This was introduced in the 7700E, but they had to rewrite it in order to support MDA and PAV (9980V I think). MDA works without a PAV license.

If the Operating system *thinks* the device is busy, the IO is queued off the UCB and never even tried until it comes to head of queue. You MIGHT have up to three times as much data behind the actuator. That depends on how fully loaded the three mod-3s are which are to be merged onto the same single mod-9; i.e., it depends on which three mod-3s you choose to merge together. If all data sets on all volumes are equally and randomly accessed, then you will have three times as much requirement to access the new mod-9 as any of the three mod-3s had which were merged. However, most data centers have highly skewed access patterns. 80% of the actuators might have only 20% of the total I/O workload. Which means your volumes are almost certainly NOT equally and randomly accessed. You have some volumes that are almost never accessed and some others that are accessed all the time. When z/OS starts in I/O on DASD device , z/OS turns on a flag bit in the UCB for that device that indicates that this particular z/OS image has started an I/O on that device. But if the device is shared, then another z/OS image may have already started an I/O on the same device, turned that same device's UCB flag bit on in its copy of the UCB

Give the starting position, length and format of each relevant field. Give the RECFM and LRECL of the input files. It's also difficult to determine where your fields are from you post, so feel free to send me the input and expected output offline (yae...@us.ibm.com) as plain text files so I can see what they really look like.

Is there a no cost replacement for EKM?
We are getting ready to upgrade to z/OS V1.13 and have a question of EKM (Encryption Key Manager). I know that if I do not hold onto the Java 1.6.0 files - it might not work. So is there a no charge replacement for EKM? Or is IBM forcing customers to go to Tivoli Key Lifecycle Manager?

Re: Is there a no cost replacement for EKM?
You just need to install multiple instances of the JDK retaining your older JDK prior to 6.0.1. GEICO has so far refused to upgrade from EKM to ISKLM till we either acquire hardware or need function like full disk encryption not supported by EKM. Attaching E07 drives native is not supported by EKM. http://publib.boulder.ibm.com/infocenter/ts7700/cust/index.jsp?topic=%2Fcom.ibm.storage.ts7740.doc%2Fts7740_drives_3592.html Here is part of the answer we got from IBM on the same question As you know there are multiple versions of the Java SDK for z/OS. The EKM component is still available in the z/OS SDKs listed below, and will remain in these SDKs for the life of these SDKs. The EKM component in these SDKs has not been enhanced since 2008 with new device support. If you have a deployment of the EKM component that utilizes one of the SDKs listed you can certainly continue to use these SDKs for that EKM deployment and the devices that are presently supported by the EKM component. IBM 31-bit SDK for z/OS, Java Technology Edition, V6.0.0 IBM 31-bit SDK for z/OS, Java 2 Technology Edition, V5 IBM SDK for z/OS, Java 2 Technology Edition, V1.4 We will be upgrading from z/OS 1.12 to 1.13 starting next month and don't plan on replacing EKM yet unless something comes up unexpected.

Re: Is there a no cost replacement for EKM?
Old EKM is packaged with JAVA 6.0.It is removed in 6.0.1 and up. As long as JAVA 6.0 is in support, I would think that version of EKM would be ok yet. And it does appear to be true that IBM is now charging for the replacement ISKLM product, but it us usage based. However, it does not appear to be very expensive, and it the lite version that does not require DB2 backend or the SSRE(system services Runtime environment, which I believe to be OEMWAS). We did migrate to it. Gonna be hard to explain to the PHB when you can't read your tapes anymore if you run on something unsupported. Does it stink that IBM is now charging for something that used to be free? U bet. Although it seems you should be able to 'negotiate a price since you purchased the hardware encryption feature on your 359x drives that is worthless without it.

Re: SHARE Atlanta March numbers
Ken, Yes, many, many years ago the numbers were in the range of 2500 - 3000 or more. It is when IBM decided that they can make money and completely control the content with their own conferences that SHARE attendance lowered. Many execs see the IBM tag and immediately think it must be better, but that is not the case. SHARE offers a diverse audience and session content, with non-IBM speakers and solutions. Any time I am asked which conference to go to I quickly recommend SHARE. (Full Disclosure: I am the Deputy Project Manager of the CICS Project at SHARE) The ability to talk to and hear presentations from and about vendor solutions without the IBM slant is what is in the best interest of the attendees. IBM makes great products, but there are vendors out there that enhance the IBM products and should be heard also. (GT Software, ASG, BMC, HostBridge and many more.) This does not happen at the IBM sponsored conferences. With that said I would guess that the attendance at the Atlanta SHARE would be over 1000. But that is just my guess. Glenn Glenn A.

Re: ASM and HiperPAV
To be precise: ASM reserves 2 exposures *per pagedataset* not per volume (i.e. 2n-1 Aliasses per volume), since/so you can allocate more than 1 pagedataset on one volume. We do so to fill 3390-9s and -27s with pagedatasets. I beg to disagree. :-) HiperPAV works on a per-IO-basis in the hardware, so ASM cannot 'reserve' an exposure (anymore). HiperPAV is for faster I/O turnaround and for reduction of IOS queuing times by giving another SSCH another 'exposure'. No SSCH, no HiperPAV usage. If no I/O is started because ASM knows there is one outstanding (as was the case in the past) then HiperPAV is effectively not used. Other than for the second case that Jim Mulder had detailed in the past. Hence my question if that is still true or if ASM now starts as many IOs as needed to get paging requests filled. For a page data set on a HiperPAV device, ASM creates two sets of channel program control blocks. If a single page read request come along while the first set is in use, ASM will use the second set to start another channel program to do the single page read. The purpose is to avoid having a single page read need to wait for a long string of pageouts to complete before it can be started. Jim Mulder z/OS System Test IBM Corp.

Re: Is there a no cost replacement for EKM?
Old EKM is packaged with JAVA 6.0.It is removed in 6.0.1 and up. As long as JAVA 6.0 is in support, I would think that version of EKM would be ok yet. And it does appear to be true that IBM is now charging for the replacement ISKLM product, but it us usage based. However, it does not appear to be very expensive, and it the lite version that does not require DB2 backend or the SSRE(system services Runtime environment, which I believe to be OEMWAS). We did migrate to it. Gonna be hard to explain to the PHB when you can't read your tapes anymore if you run on something unsupported. Does it stink that IBM is now charging for something that used to be free? U bet. Although it seems you should be able to 'negotiate a price since you purchased the hardware encryption feature on your 359x drives that is worthless without it. Here is the link to the announcement(watch the wrap): http://www- 01.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ssi/rep_ca/0/872/ENUSAP11 -0100/index.htmllang=enrequest_locale=en Thank you both Sam Knutson and Dave Jousma. I remembered a year or so ago when this came up it was considered TKLM lite and no charge. It is a shame that IBM seems to be back-dooring the demise of EKM without being more upfront with it. I am now wondering what other EKM-like products are out there and what the cost comparison is to ISKLM. I know there is CA Key Manager, and IBM TKLM/ISKLM. But are there others? The main reason (besides no charge) we got EKM is because we do not have an Crypto Card on the z10s and we only run the E05/TS1120 tape drives with encryption.. So this may be also something we have to look at. Lizette -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN

Re: TOD clock format
You mean: The current value of bits 0-63 of the TOD clock is stored in the eight-byte field designated by the sec- ond-operand address, provided the clock is in the set, stopped, or not-set state. When the clock is stopped, zeros are stored in positions to the right of the rightmost bit position that is incremented when the clock is running. For STORE CLOCK, when the value of a running clock is stored, nonzero values may be stored in positions to the right of the rightmost incremented bit; this is to ensure that a unique value is stored. For STORE CLOCK FAST, when the value of a running clock is stored, bits to the right of the rightmost bit that is incremented are stored as zeros. Zeros are stored at the operand location when the clock is in the error state or the not-operational state. The quality of the clock value stored by the instruction is indicated by the resultant condition-code setting. For STORE CLOCK, a serialization function is performed before the value of the clock is fetched and again after the value is placed in storage. Resulting Condition Code: 0 Clock in set state 1 Clock in not-set state 2 Clock in error state 3 Clock in stopped state or not-operational state Program Exceptions: . Access (store, operand 2) . Operation (STCKF, if the store-clock-fast facility is not installed) Programming Notes: 1. Bit position 31 of the clock is incremented every 1.048576 seconds; hence, for timing applications involving human responses, the leftmost clock word may provide sufficient resolution. 2. Condition code 0 normally indicates that the clock has been set by the control program. Accordingly, the value may be used in elapsedtime measurements and as a valid time-of-day and calendar indication. Condition code 1 indicates that the clock value is the elapsed time since the power for the clock was turned on. In this case, the value may be used in elapsed-time measurements but is not a valid time-of-day indication. Condition codes 2 and 3 mean that the value provided by STORE CLOCK cannot be used for time measurement or indication. 3. Condition code 3 indicates that the clock is in either the stopped state or the not-operational state. These two states can normally be distinguished because an all-zero value is stored when the clock is in the not-operational state. 4. If a problem program written for z/Architecture is to be executed also on a system in the System/ 370 mode, then the program should take into account that, in the System/370 mode, the value stored when the condition code is 2 is not necessarily zero. 5. Two executions of STORE CLOCK FAST, or an execution of STORE CLOCK FAST and STORE CLOCK, either on the same or different CPUs, do not necessarily return different values of the clock if the clock is running. Thus, the values returned by STORE CLOCK FAST do not necessarily indicate the correct sequence of execution of the instruction by one or more CPUs. 6. When the TOD-clock-steering facility is installed, and assuming a valid operating system, then, for the problem program, the TOD clock is always in the set state and there is no need to test the condition code after issuing STORE CLOCK or STORE CLOCK FAST.

C++ files certainly may be multi-line, just like C. What is the originating system? I have seen this sort of thing when an ASCII file has UNIX style line endings (LF only) and the ftp is done by a Windows system (which wants CRLF). Instead of using notepad (which makes me think you are using Windows), try using wordpad. I don't do Windows myself, but I've heard that wordpad will properly recognize the UNIX style line endings. You can then do a save function and wordpad will change the line endings from UNIX style to Windows style. This may well allow the ftp to succeed.

Re: TOD clock format
Regrettably, the current PrOp in not specific about the time horizon of the STCK instruction. At 23:58:43 on 17 September 2042 the IBM mainframe TOD clock, 64-bit STCK value overflows. STCKE values do not have this defect. Effectively, they are 14-byte, 8 x 14 = 112-bit [unsigned] values. (The rightmost two bytes of the full sixteen-byte value ensure uniqueness when there are multiple TOD clocks in an environment, but they are not part of the TOD value proper.) There is thus no excuse for any use of an STCK instruction in NEW code. Old code is a different matter, If it is judged that there is NO possibility that it will still be in use in 2042, STCKs in it need not be replaced. Otherwise they should be. --jg -- John Gilmore, Ashland, MA 01721 - USA -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN

Re: CPP (C++) file on z/OS
I do this daily. It's not a cpp problem -- it's a file conversion and line-ending problem. I use Ipswitch WS_FTP. Where did the file originate? .cpp sounds like Visual Studio, so it should have correct Windows line endings, which are essentially a superset of UNIX line endings. .cpp files on Windows should have CR-LFs. It sounds like it is wrong before it ever starts out. BTW, it will want to be a .C (upper case) file to compile it with the IBM C compiler.

Re: ASM and HiperPAV
For a page data set on a HiperPAV device, ASM creates two sets of channel program control blocks. If a single page read request come along while the first set is in use, ASM will use the second set to start another channel program to do the single page read. The purpose is to avoid having a single page read need to wait for a long string of pageouts to complete before it can be started. Jim, that's what you told me some time ago - and what I have presented in Memory Matters: 2 effective per page data set. When I present on the support for 4GB page data sets I verbalise the trade off between the simplicity of fewer, larger, page data sets vs the larger number of channel program control blocks for more, smaller, page data sets. Because of the virtualisation within modern disk controllers robustness favours more, smaller. So to summarize: Page data sets can be up to 44,9GB in size (supported by ASM in using it), HiperPAV is used, but 'only' two IOs will ever get started for the same page data set at the same time. Jim, thanks for clarifying the current state. Martin, that means I have to attend the latest 'Memory matters' in May, right? :-) The reason I asked is that the DB2 colleagues have demanded an (almost) free-for-all memlimit for all address spaces. (Due to a clear abend0c4-4 on two getmained addresses in a BMC utility that they say is caused by not-enough-storage above the bar.) They will get 32GB per asid, which in turn means that we will now see drastic increase in paging, which was bad here to begin with (around 30% per page data set already). So we system guys need to redesign our paging setup, hence my question after studying ibmmain. For the curious: Doubling the memlimit from 500MB to 1GB increased paging to the same number of page data sets from 18-22% to 28-31%. Now we won't catch those applications anymore that just get 20GB, touch every page (which gets them backed) and then never use it because there just isn't any activity in the product on that system. But the locals will surely get filled up. Barbara -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN

You can then do a save function and wordpad will change the line endings from UNIX style to Windows style.
