Yours is almost as good as the one to replace the VM Toolsrun-based employee directory by LDAP because the VM solution required updates to be applied to all copies of the data spread over multiple VM system I believe IBM set back the clock 10 years by migrating off their VM applications internally. When you have a decent interface between business logic and presentation layer than served the purpose already for 20 years, really how many people do you think need to be involved with 3270 data stream programming? In fact, that interface was lean enough to allow for small projects to access the applications through web browser or even WAP phone. What really increased development cost was to replace development teams and rewrite the business logic on another platform. Many web applications today still follow that classic form based transaction model like we have with DMS, ISPF, IOS3270, or Xedit-based applications. That only model changes with WEB 2.0, and I already demonstrated we can drive an AJAX web application with our CMS-based ESAWEB server. Guess what, the CMS code was just 10-15 lines of REXX and Pipes to make it work. The rest is AJAX just like it would be on another platform. And an application takes a *lot* of AJAX code to make it work, but that's another issue. Rob

I have trying to stay on the sidelines of this conversation. However, IBM MUST get their act together on IBMLINK. Every so often I get an email from IBM indicating that a status record has been updated. It took 3 months to get an answer on where I should look and how to look at the updated status record. I had one techie tell me that I should just ignore these records as no one at IBM knew how to look at them either. I have 'tremendous confidence' in level one people now.

Rexx performance question
We have an old REXX exec that I had to modify. This is a rather simplistic description but it consists of 2 parts - 1 to set up the environment(variables) and 2 to use the variables setup in 1. Bottom I had problems modifying it so I re-wrote it. The original used GLOBALV extensively - part 1 would do PUTs and part 2 would do GETs. Besides a lot of 'steam lining' I thought I would be 'clever' and changed the GLOBALVs to 'PIPE var VarName 1 | var VarName'. However the new exec ran much slower than the old. I then did a test to only compare GLOBALV PUT/GET to setting and retrieving the variable with PIPE var stage. The pipe stage was much slower. I thought the pipe logic would be better - obviously mistaken. Any comments - any other method I could have used that is perhaps faster than GLOBALV? Thanks Peter

Re: Rexx performance question
From my testing, PIPES incur quite a bit of overhead when starting up. So, optimising means doing as much as possible within a PIPE to amortise that overhead over as much work as possible, and therefore using as few PIPE instances as possible.

z/VM 4.4-- 5.2
I'm still unable to get to the www.vm.ibm.com web site and need some information of features/enhancements etc offered by z/VM 5.2 over 4.4. We're currently using z/VM 4.4 (32 bit) and I've been asked to gather some information on the benefits of 5.2. Could somebody please send me some bullet items... 5.2 is a fait accompli and will happen in the next few months, but I need some highlights... 64 bit is the thing I'm most aware of, but are there new features in CMS that users can benefit from, or are all the improvements in CP, new hardware support, and the sysprog functions?

Re: Rexx performance question
Using a file to store the variables a while, uggghhh... File I/O remains terribly slow compared to memory access, even though you might save some CPU (I don't know if you will save) the result may be code than takes longer to complete in elapsed time. The fact that EXECIO is faster than PIPE to write files is that one often sees execs that every now and then write to a file. If you do that with PIPE, the file is closed after each write request; with EXECIO, the file is only closed when you explicitly ask for it. Again, the general rule is: do as much as possible in a single call, to PIPE, to XEDIt, to 2007/1/12, [EMAIL PROTECTED] [EMAIL PROTECTED]: From my testing, PIPES incur quite a bit of overhead when starting up.

Re: z/VM 4.4-- 5.2
I'll send you a 5.2 PDF presentation, it seems to start from 4.4 2007/1/12, Don Russell [EMAIL PROTECTED]: I'm still unable to get to the www.vm.ibm.com web site and need some information of features/enhancements etc offered by z/VM 5.2 over 4.4. We're currently using z/VM 4.4 (32 bit) and I've been asked to gather some information on the benefits of 5.2. Could somebody please send me some bullet items... 5.2 is a fait accompli and will happen in the next few months, but I need some highlights... 64 bit is the thing I'm most aware of, but are there new features in CMS that users can benefit from, or are all the improvements in CP, new hardware support, and the sysprog functions?

What is wrong with using GLOBALV? That can be memory-only as indicated in the original post (it specified GET and PUT, not GETS, GETP, PUTS or PUTP). There is no need to write to disk unless you need for the variables to be retained across IPLs or logons (SESSION or LASTING GLOBALV). Since it is strictly memory access, it ought to be faster than using either Pipe or EXECIO.

Re: Rexx performance question
I'd say there's nothing wrong with GLOBALV, but plumbers use their Piping tools. GLOBALV has an extra advantage: it is clear to the reader when one shares variables between execs. With a PIPE in a called exec one can do anything that the reader of the calling exec will not be aware off. Something more I remember: when REXX's VALUE function was extended to support GLOBAL variables, we were told that using VALUE() was faster than the GLOBLAV command. But, only when compared to GLOABLV with a single variable, so 'GLOBALV GET V1 V2 V3' outperforms 3 calls to VALUE(). -- Kris Buelens, IBM Belgium, VM customer support 2007/1/12, Stracka, James (GTI) [EMAIL PROTECTED]: We have not heard from Michael Coffin on this subject.

No argument from me. The other point is: does it REALLY cost IBM anything significant to support a stable application? Yes. If you are going to support it, then you must have the ability to - reproduce the problem in-house - alter the application - test the application Perhaps just functionally stabilizing it, and telling us we have to look for new features in IBMLink 2000 would suffice. We could continue to use the legacy (i.e productive) tool for what we've always used it for, and get familiar with IBMLink (and report feature failures if it actually helps) for new features. That leaves two interfaces to the backends. That means the backend or an extra layer of middleware must support this access method. You can't make changes to them without consideration for the 3270 side that is stablized. Regression testing is then required. There goes the idea of zero-cost maintenence. And I say this as a 12-year veteran of System Test. If something is stabilized, that means no new function BUT the old function remains usable. THAT means testing changes to ensure you haven't broken it. If at first you don't succeed, try, try again. One of two things will happen: You'll change your process to conform to the abilities of the tool, or you will change the tool to conform to your process. Naturally, in the real world, some of both will happen, but decide which you would prefer more of and then take action to achieve that goal. If you choose not to persevere with Feedbacks and dialog, then your process will change far more than the tool will. I wish the 3270 interface would remain for you, too. (I don't get access to either one. :-( ) Since the announcement, I'm sure that all of the Feedbacks the 3270 users have opened with their [detailed and specific] objections are being reviewed. Ummm all y'all *did* open Feedbacks, right? Not just blowing off steam here? BTW, I'm guessing that 3270 is better. Long live 3270. is probably not going to get any attention. Explain *why* 3270 is better for *you*. Be specific. Alan Altmark z/VM Development IBM Endicott

Re: IBMLink 2000 Finding ESO levels
IBMLINK 2000 reminds me of Conan O'Brien's running gag on the Late Show about looking into the future...all the way to the year 2000! :-) Maybe it's time for an IBMLINK Vista version! Whoops I didn't say that, did I! Happy Friday! Dale R. Smith Technology Services Senior IBM Global Services [EMAIL PROTECTED] 1-614-481-1608

And those new hires out of college are certainl y not very good at 3270 programming, you know ;-) That the 3270 interface on IBMLink remained for 7 years (long past the original sunset schedules) is a testimonial to the IBMLink team's committment to you. They fought to keep it. Quite reasonably, TPTB don 't like redundant investments and I was gratified by their ability to keep both interfaces running for so long. Alan Altmark z/VM Development IBM Endicott = == == I'm not opposed to webifying the application. I seem to remember a SHARE Task Force trying to convince IBM to use the Internet (for software downloads, dump uploads, e tc.) I just object to them throwing away perfectly good function and either not replacing it at all or hiding it so well. They did a really poor job of webifying it. It seems in seven years they could have moved over all the existing funct ion. They kept telling us more was coming -- where is it? You say they fought to keep green screen, while I had the impression that they were dragging it out because it was taking so long t o finish the job. The software download function used to let me identify what I needed to o rder, now it just expects me to know by black magic (or another IBM website for which they provide no link.). IBMLink green screen had perfectly good P and Q (Print an Print All) comm and -- where is this in IBMLink 2K? The SIS function had directed searches -- now you are somehow expected to know that the correct strings are, for example: PERVASIVE|HIPER PIDS/568402600 LVLS/300 | R300 (That one of the four strings to search for HIPER APARs for BookManager.) Or did I miss something else? Fortunately I saved all these strings that I use. I couldn't figure out how to view a single PTF until Marcy told me. It took me quite a while to figure out that if I want to ADD products to ASAP I have to find the Add link hidden in the right-hand menu, not at the bottom near the Delete but ton. Should I open an IBMLink feedback on each of these? (I already did on 2.) I sure didn't like the answers I got for those two. Are you sure there is anyone listening?
VTAM Support
