Re: What is the current feeling for MVC loop vs. MVCL?
This thread has been really informative. I am going to put this to use. I have code that is executing a million or so ~8K MVCLs a day. I have other things on my plate at the moment but I will replace that with an MVC loop at some point. It seems to me like the ideal way to do this would be to have not two stages (MVC for 256 and EX'ed MVC) but rather three cases: A loop with a hard-coded or unrolled string of 16 MVC's that moved 4K blocks and incremented registers by 4K on each iteration; followed by a loop of 256-byte MVCs; followed by an EX'ed MVC for 1 to 255 bytes.

Re: What is the current feeling for MVC loop vs. MVCL?
I am going to digress a bit here. I got into a discussion with Martin Packer about some of this and it raised a few interesting thoughts : (1) What percentage of executed MVCL instructions are for clearing storage versus actually moving data? I know that in the software I am involved in, that MVCL(*) for clearing is used *way* more than any movement purposes as I am a heavy user of CPOOL services. Obviously you can have fast clear for objects with lengths that 256-multiple using n*XC - however I have often wished for a ZERO=YES option on the CPOOL BUILD so that you are guaranteed a clean cell for each subsequent CPOOL GET. If anyone else agrees, I might consider raising a Share requirement (2) Is there any performance difference in MVCL when L2 is zero? I seem to recall hearing a while ago that there might be...however am not sure. (3) How does MVC v MVCL compare in AR mode with source and target using different ALETs ?

Re: What is the current feeling for MVC loop vs. MVCL?
The optimizations that compilers use are certainly interesting in the sense that there are things to be learned from them. They do, however, have two limitations. They are particularist, appropriate usually but not always to the run-time environment in which a particular compiler's output will be executed but often less so in a different environment. (Both advantages and disadvantages have, for example, attended the use of shared optimizing machinery by IBM PL/I and C.) These optimizations are also devised by groups whose full-time job is to optimize code skeletons that are used stereotypically in compiler-generated code; and these groups inevitably come to have a vested interest in cleverness, i.e., non-standard, less than obvious ways of doing things. I have been dismayed by this thread. It would be better for almost all of us almost all of the time to use MVCLs, devoting the time not wasted by examining clever alternatives to them to more significant problems.

Obviously you can have fast clear for objects with lengths that 256-multiple using n*XC - however I have often wished for a ZERO=YES option on the CPOOL BUILD so that you are guaranteed a clean cell for each subsequent CPOOL GET. If anyone else agrees, I might consider raising a Share requirement Such a requirement would likely be rejected. There isn't anything CPOOL can do to obtain better performance for clearing a cell than what you can do in your own code. Clearing done by CPOOL would be guaranteed to be at least marginally slower, and in some cases considerably slower, than clearing done by your code. (2) Is there any performance difference in MVCL when L2 is zero? Well, at least you can't get any cache misses on the source when the source length is zero. -Original Message- Behalf Of Charles Mills Sent: 01 June 2011 14:20 Subject: Re: What is the current feeling for MVC loop vs. MVCL? This thread has been really informative. I am going to put this to use. I have code that is executing a million or so ~8K MVCLs a day. I have other things on my plate at the moment but I will replace that with an MVC loop at some point. It seems to me like the ideal way to do this would be to have not two stages (MVC for 256 and EX'ed MVC) but rather three cases: A loop with a hard-coded or unrolled string of 16 MVC's that moved 4K blocks and incremented registers by 4K on each iteration; followed by a loop of 256-byte MVCs; followed by an EX'ed MVC for 1 to 255 bytes. (Obviously each step would be optional depending on the exact count.) Thoughts? If your 8K MVCLs have 4K-aligned sources and targets, then they may be taking advantage of the page mover hardware.

The optimizations that compilers use are certainly interesting in the sense that there are things to be learned from them. They do, however, have two limitations.

Re: APF Authorization
Hi friends! Can anyone suggest a reason why a job runs fine with APF authorized loadlibs when the actual files are used, but fails as unauthorized when using a dataset alias? APF shows the correct file on the correct volume, and I know that I do not need to add the alias name to APF list, right? What other things can I check, and is there a way for a file to lose APF when using an alias? My understanding is that the Alias is only used to locate the real file from the catalog, but then when it is opened, the real file is used. Thanks in advance for your thoughts and help! *don* Don, To make sure I understand, you created JCL that uses a STEPLIB or JOBLIB that points to DSN=X. However X is an alias for DSN=Y. The job fails if the dataset is NOT APF Authorized. Is that correct?

Re: APF Authorization
Lizette, I'm sorry for my cloudy description - let me try to be more clear... We have a STEPLIB with 2 files in it. The real filenames are MY.APF.FILE1 and MY.APF.FILE2. These files are APF authorized. When the job uses these names in STEPLIB, it runs fine. Now I have an alias called MY.ALIAS.FILE1 for MY.APF.FILE1. When my application runs with this alias file, the application checks to see if it is authorized (it is a vendor app), issues a message telling me it is not authorized and then ends.

Just guessing, but APF is simply a list of libraries and volsers etc. If you call the library by another name it won't match what's in the list.

A wild guess is that the vendor software is using the MVS TESTAUTH macro which is about the simplest API in z/OS.

Re: Z/os FTP Server Configurartion
Hal, If the FTP Server is a z/OS FTP server, then I don't believe there is such a thing but I'm not sure that I completely understand your situation. The usual problem is that the port command (which passes along the FTP control session) contains an IP address and the Server/Client sending the port command is unaware of its NATed address. Please forgive me for answering a question with more questions but I have three: 1) Are both sides of the FTP session NATed? If not, which side is NOT NATed? 2) What product (and manufacturer) is the client software? 3) What product (and manufacturer) is the server software?

Re: Z/os FTP Server Configurartion
Hal, I should have read the title of your post :D. Then I'd know that you're using the z/OS server. After establishing the FTP session, type the following SITEEPSV4 LOCSITE EPSV4 I can't guarantee that the LOCSITE command will work on the FTP client you're using. EPSV4 is the IBM keyword used to activate the EPRT and EPSV commands described in RFC 2428. In passive mode, the client will send a EPSV command to the server (rather than PASV). This is similar to the PASV command EXCEPT that the server responds with EPRT (rather than PORT), which specifies a port number ONLY. Thus, the client establishes the data session using the same IP address that was used to establish the FTP session (i.e. the server's NATed address).

Re: What is the current feeling for MVC loop vs. MVCL?
It's not just OOO that gives optimized compilers an advantage over manually crafted assembler. It's been true since zArchitecture that to write highly effecient code one needs knowledge of the pipeline There was a redbook when the zArch machines z/800 z/900 came out that mentions the non-sequential code that compilers generate. http://www.redbooks.ibm.com/redbooks/pdfs/sg246515.pdf snip There is one programming aspect that is relevant, although only slightly linked to the use of a split cache. For many years, it has been an axiom among S/360 - S/390 users that assembly language programmers probably produce faster code than high-level language compilers. This is no longer true. Processors that use pipelines (including z800 and z900 machines) require a certain amount of nonsequential code to obtain the best performance. For example, if an instruction loads a register and the next instruction uses the register, we do not have optimum code. This sequence will stall the pipeline for several processor cycles. (The instructions work correctly, of course, but they take longer than necessary.) The best technique is to interleave several unrelated instructions between loading a register and using the new contents of the register. This is not natural, sequential thinking for an assembly programmer, although he could learn to do it. IBM’s recent S/390 compilers contain logic to produce this sort of optimized code.

Re: XMIT INMR01 record question
Gil: In those cases (very few) which the data set names were secure What I did (for FB type ds) was to use a utility that created in iebupdte form the entire PDS. No dataset name was disclosed (you basically /*xmit the job to the other end and create the dataset with iebupdte on the other end). If you need loadmods there are one or two other methods to do so. VSAM you can do an export temp and then reblock it into 80 byte and /*xmit and reblock it and import it.

There is a section called TRANSREC that is used for the defaults for the TRANSMIT and RECEIVE commands. You may be able to, but I may not. This is a problem for someone who wishes to use TRANSMIT as an interchange protocol but does not wish to disclose one's internal host names, user IDs or data set names. One is reduced to writing a program to edit the INMR* units post facto. Actually not too hard because the package is not protected by any sort of checksum.

Re: Delete Sub directory under /Service
I mean, when we define any variable in USS using SET command ( Like *SET $SYSNAMEXYZ*), then in which file system store these values. As of now I just want to see that what are all variable has been defined currently in USS. Regards Saurabh On 6/1/2011 10:38 PM, Neubert, Kevin wrote: You mean /etc/profile and such?
