Going back to the '70s, I vaguely remember a rule of thumb (if you were building a shop or converting from non-IBM to IBM): If you are going to run up to 3 CPUs (basically a Box, or CEC as it would be called today) in a site, you would use JES2 because JES3 Global was expensive (in CPU cycles). If you were going to have 3 or more CECs in a site, you would give strong consideration to JES3. Today, I have been looking at features I was familiar with in JES3 and it appears to me that many of them have been moved to BCP (basic control program) to make SYSPLEX operations easier to do. A good example of this is the change in console support and command routing. From my perspective, and this is just my opinion having NOT used JES3 under z/OS, the only thing that JES3 would buy us today is the JOB scheduler that JES3 had, and Job Set Up. JOB Setup is a foreign concept to anyone who has done JES2 only. And it causes heartburn for people having to provide a JOB stream to/for a JES3 environment. The idea that JES3 and MVS can both manage tape drives/mounts and JES3 requires the data sets to exist before the JOB starts (otherwise you get a JCL error -- UNLESS the data set is created in the JOB via JCL) is hard for some to get their hands around. I have done work for a US Gov't agency, that was running a single CEC with JES3 Global and no locals. As I understood it, they did this because they were dependent on the JES3 job management (job scheduler) system. But they could not otherwise justify JES3. And if they had not been a JES3 shop in years gone by, they would have just gotten a simple job scheduler. I would like to hear from current JES3 users and what they think.

My requirements are support (well supported), cost, encryption and usage across a wide platform (z/OS, Linux, Windows, etc...). And it has to be deployed via Citrix. I am not sure what anyone else is using out there for this type of software. I love Vista3270 but I am not sure that my company will even look at it. SNIPPAGE I personally use QWS3270 Plus. There is also a secure version (does SSL as I recall). I have run it on Linux using Wine (not the secure, as I don't have that variant). It is well supported, and as far as I am concerned, the price is good (QWS3270 Plus is less than US$30 single seat the last time I priced it). I am not a Citrix user, so I have no idea about how QWS will interface with it (we have Citrix here, I am just fortunate to only need a normal VPN). The biggest kicker that I have come across in evaluating 3270 software: Scripting language and how it is supported. If you already have a system written using one language, will it easily port to another 3270 emulation system? The next one, which is much more important to me is, can I map my keyboard (whether it is a keyboard or a laptop keyboard wannabe) to behave as much as possible to a real 3270 keyboard, including all the programmable keys (PF and PA)?

Kripke Sent: Sunday, July 18, 2010 5:09 PM To: IBM-MAIN@bama.ua.edu Subject: Detecting when a READ/GET crosses a concatenation boundary Hello; I wish to detect when a BSAM read or QSAM GET crosses a concatenation boundary. I am guessing I need to code an OPEN and EOV DCB exit to get control. The input data sets can reside on DASD or TAPE, but, the environment does not mix unlike devices...all one way or the other. Purpose: Be able to the extract the dsn actively being processed. Environment has specifc dsn naming conventions that tie back to a cycle number and the generating jobstream. Any assistance/tips would be greatly appreciated. SNIP DFSMS Using Data Sets gives some tips in this area. Look at the area covering Concatenating Data Sets Sequentially. The OPEN exit is driven for each data set in the concat as the Access Method switches to it. So from this, you should be able to get the DSN. And the Label exits get driven as well. Take a look at Using Non-VSAM User-Written Exit Routines with the specifics of Open/Close/EOV Standard User Label Exit. So you are on the right track. Beware of mixed mode (24/31 bit addressing), it can get you really lost when trying to diagnose a problem. Also, look out for LBI -- you have said something about tapes. They can be in LARGE BLOCK (32K) and certain things may be different for the exits (I can't remember exactly how that works -- I get to diagnose problems with our code from time to time).

Re: Delete all members of a PDS that is allocated
I just have to ask this one question. How difficult is it to get the number of directory blocks from a PDS in a _ program (where the blank can be filled in with COBOL, PL/1, REXX, etc., but not HLASM/ASM) and then open the data set with RECFM=U and then write an initial directory block followed by n empty blocks? With that question asked, if it is not so difficult, wouldn't that allow you to clear a PDS right rapidly?

A colleague has written me about a set of circumstances he is observing: Program A is authorized, running in Key 7, TCB mode, and issues a LINK for Program B. When Program B gets control, it finds PSATOLD=0 and PSASRBM=04. Program A's state was verified with a S0C1 just before the LINK, and Program B's state verified with a S0C1 at entry. How could LINK possibly give the target program control in SRB Mode? Offhand, I don't know the z/OS release he is running on but I expect it would be at least 1.8. SNIP I had asked this same question of Dump Services people. I will summarize what was said. Basically, when an sdump is being taken of your address space, the CPU it (SDUMP) is running on, is in SRB mode. If that was also the same CPU you were using, it may appear in the dump to have been in SRB mode, but when your program was running it may well have been running in TCB mode. IF PSATOLD is zero when your program checks it (while it is being dispatched), it is NOT in TCB mode. If this is not true, and you can otherwise prove you are in TCB mode, you have the opportunity to cause IBM to take an APAR (probably for a dispatcher bug).

If you don't limit those volumes and they get actively used by both systems (as opposed to specific manual managed file processing), MVS goes nuts recovering the free space DSCB(s) for those volume's VTOCs (which happens every time MVS needs to read a contaminated VTOC to get space).

I'm trying to write some authorized code that has a requirement to invoke unauthorized user exits. I'd like to be able to do the following. 1) Provide an anchor word so that the user exit can allocate and retain memory from call to call. 2) Pass a buffer of data (or the address of the buffer) to the user exit so that the user exit can modify the data. 3) Allow the user exit to pass the address of data it has generated back to the authorized caller. 3.1) Data in item 3 will most likely be in a different buffer than data in item 2. Pointers (with enough detail please so I can do the research) on how to do this and maintain system integrity will be greatly appreciated. Thanks, Sam SNIP One of the ways to protect yourself is to force the EXITs to use a storage key that is different from yours, and enforce that rule. Why? The EXITs are running in your address space, and so may change storage that is in the key they are running in. So can you attach them such that they will be in KEY10? Or, can you set up all your code to be loaded in KEY10 or KEY0 so that the exit code can't modify your code? Now, can you put all of your control blocks (or structures) in KEY10 or other than KEY8/9 if the exits will run in KEY8? If the exits will run in KEY10, then you can operate normally. Now, any address that is passed back to you, must be checked for a valid storage KEY. It can't be an address of your storage. If it is, the EXIT has passed a bad address. OR, the address passed back to you must be an address you passed it. But now, how do you tell if the EXIT wrote beyond what you intended? If the EXITs run in a different address space, you can use PC/PT/PR to deal with all of this. I'm sure there will be others who will give more gotchas for this type of problem.

This last winter a similar excuse for transport disruption borrowed the headline as The wrong sort of snow. And in case, you haven't seen the news, the air space of a large part of Western Europe has been closed since it turns out that the particles being put out by the volcano - situated so conveniently in the middle of the busiest air corridor on the planet, given their genesis, are particularly harmful to jet engines. Having sent the letter, I was amused to see that an aeroplane providing pictures of the eruption was - you guessed it - propeller-driven! SNIPPAGE At 160 KIAS (Knots Indicated Air Speed) and beyond (which Propeller aircraft are capable of), the ash and grit from a volcano is rather corrosive to the leading edges of wings, windshields, etc. But it is much more sensational for the unknowing reporters to say that jet engines are more susceptible to damage... However, having wings develop holey (not Holy) leading edges in flight tends to make flight crews into test pilots with no real warning... I would also imagine that the aircraft taking the pictures was making sure that they were staying clear of the ash plume.

Hello, My understanding is that DB2 CAF for CICS and batch environments are different because of which two different load modules are needed to run in these environments even when the actual program may be same. In my project there are many COBOL programs which have DB2 statements but no CICS and are needed for both batch and online. They are just service programs. Currently we have to create two different programs with almost identical code to get two different load modules. If there is some way where we can have only one program load module work in both environments, it will be very helpful. We are using CA-Endevor as change management software which also currently can not create two physically different load modules for the same code otherwise that also could have worked for us. SNIP Capture the OBJECT deck output from the COBOL compiler. Now run two different linkedit steps, each will point to the OBJECT that was captured, but will have different INCLUDE statements to control the output.

So, once the system is installed, you have specifically not backed up your certificate file/database so that the rest of the tapes are un-usable. Is that also correct? Now you need a way to get that information into your system, using some special knowledge (such as the password, or key code) that allows this repository to be installed making your cert file/database available.

So wouldn't encrypted 'data at rest' be a DFSMS issue (or some third party that is somehow invoked to do this)? Which would be handled by the file / database situation to which I referred above.

But what were the environmental requirements for these boxes? If you go to the next level of server, and leave the clusters of floor models, you have to go to a rack and the blades.

Re: z9 / z10 instruction speed(s) -- OCTANE of CPUs
SNIPPAGE So the next time I fill up at the gas station the price should be based on horsepower. All the SUV's should pay vastlly more for the same gas that I use for my Honda Civic. I always use high-test since high-octane is always better even for small cars, better mileage and cooler running engines. The grade of gas used affects the temperature of the engine. It is one reason, why airplanes use special high octane gas. SNIPPAGE It may be one reason, but it is not the defining reason. 80 Octane is not readily available in the US any longer, so 100LL is what is used. 100LL (Low Lead -- as in TetraEthyl Lead) is needed to avoid detonation in high horsepower engines. The other octane levels are gone (unless on a military field, but since I don't operate there, I can't really say what their octane ratings are). And this is why there are people pushing for AutoGas STCs, but requiring that the autogas NOT have alcohol in it (since it attracts moisture, and climbing out to 10,000 ft MSL can mean the outside temp is -30C in the winter guess what happens). sore subject for me But today, even the low end auto engines have detonation sensors to change the timing and mixture. So running premium is a waste. The idea that we need different CPUs to allow for different workloads is a bit twisted. That the clock speed would be different, or the internal cache would be different, etc. is understandable. But, using certain arguments, and apparently IBM does, we do not see mainframes in the 10-20 MIP range with embedded disk drives, etc. (similar to the P/390 on steroids, MP/3000, or the FLEX/ES machines, or PSIs offerings).

Re: Entry point for a Mainframe?

In various threads there has been mention of IBM neglecting the entry level or small z/OS shops. Taking a look at the smallest of the z10s available =20 z10-BC 2098-A01 3-MSU (29 MIPS) z10-EC 2097-401 27-MSU (217 MIPS) z10-EC 2097-701 115-MSU (924 MIPS) I wonder what is considered an entry level or small shop these days. I get along on an older z990-302 132-MSUs (832 MIPS) and it seems pretty small to me. Oddly enough the 2097-701 is less MSUS but more MIPS (yes I know it is marketing and has no basis in reality). And yes I know that historically the world ran on a dozen or so 1 MIPS boxes but where would progress be without bloat. =20 Could you actually get any productive work done on a 3 MSU box today? z/OS, TSO, BATCH, CICS, DB2, Websphere, and associated monitors et. al.=20 And if you wanted more than one LPAR? (Please do not continue the LPARS more or less thread here). SNIPPAGE I could, and have, run a department off of a P390 with OS/390 V1R1, of 10 people and still had sub second response time. With a MP/3000 type machine (which I think is the truly entry level), having hard drives on board, Ethernet adapter on board (that works, Dave), and external tape drives. With this type of set up (at 30MIPS), I'm quite sure you can handle 100 CICS users, plus a few programmers using TSO. This is the level of machine IBM killed when they pulled the plug on the FLEX/ES boxes. And those boxes (FLEX/ES) were upgradeable (as I understand it) to be able to connect to the standard RAID boxes, and even have CTCA between them (once they had ESCON capability), so that you could grow into a sysplex. And what did such a box cost compared to the z10-BC? That would have been a drop, plug and play environment (pretty much a turn-key system).

Dispatcher vs. CPU (was LPARs: More or Less?)
Some years ago, there was a chart shown, that showed knees for the number of CPUs that MVS, VM, VSE could handle. Some time later, after certain updates and changes, a new chart was produced showing a new set of knees. Prior to this, Amdahl had put out the Multiple Domain Facility, after finding that there were more CPU cycles available than a single MVS could handle/manage. Is this still the case? With a Domain (LPAR to you IBM types) being able to have more than 2GB of C-Store, which reduces paging, but increases locality of reference delays, does one get max performance without 2 or more Domains running z/OS? This is strictly a CPU utilization via dispatcher question (engineering type of thing) and not a billing for software, and so forth.
