ghost dataset from non-existent catalog on work volume
Hi, I have a weird problem that I can't find a simple solution for. I have a work volume that I am processing with dss (we do it every day) and it keeps coming up with an error: ADR428E (001)-FDSDU(01), VTOC ENTRIES NOT FOUND FOR CLUSTER MEGASTAT.GRDA21A.SYS991 IN CATALOG SYS1.REGISCAT ON VOLUME WORK01 the problem is that the catalog SYS1.REGISCAT has not existed for quite a while. The dataset itself doesn't appear to be on the volume when displayed with 3.4 but it's obviously there because DF/dss can see it. I have tried to delete the VVR entry, but that fails: DELETE 'MEGASTAT.GRDA21A.SYS991' FILE(DELVOL) VVR IDC3014I CATALOG ERROR IDC3009I ** VSAM CATALOG RETURN CODE IS 90 - REASON CODE IS IGG0CLFP-38 IDC0551I ** ENTRY MEGASTAT.GRDA21A.SYS991 NOT DELETED IDC0001I FUNCTION COMPLETED, HIGHEST CONDITION CODE WAS 8 IDC0002I IDCAMS PROCESSING COMPLETE. MAXIMUM CONDITION CODE WAS 8 I think I'm missing something simple, but I can't get rid o this dataset. I can't just delete the VVDS because I have other datasets on the volume that need it. I'm about ready to move everything off of the volume and init it, but I shouldn't have to do that, and it would be like giving up. There appears to be no real harm in this dataset, but it drives me nuts.

Re: S30A-10 Abend and S878-18 abend during freemain
Hi All, Thanks for the responses. Apologies for late response. We had set a slip trap for S30A abend. We also recompiled and link- edited all utility routines and still we got the same S30A abend. We had then sent the dump to IBM. IBM got back to us saying one of our inhouse written routine used to sort contents in a memory location was somehow overlaying the storage area where DCBs of all datasets were present. This inhouse routine was overlaying just 4 bytes of memory in the DCB declarations. We just commented out the calls to the inhouse sort routine and then used an inhouse sort macro to sort the data in memory. That fixed the S30A abend for us. Meanwhile, we also found that replacing SYSOUT=* with a temporary dataset or a permanent dataset also did on give any S30A abends with z/ OS v1.7 (strange), without making any changes to code. One thing which we still dont understand is that the same job when supplied with a temporary dataset/permanent dataset runs perfectly alright with z/os 1.4 and 1.7. Where as it fails with SYSOUT=* in z/os 1.7 and runs fine in z/os 1.4. Is the SWA above/below setting the same for both systems? Is it possible that the private area size on z/OS 1.7 is different and your routine just happened to stomp on the LSQA because the gap from your allocated area to LSQA is now smaller? These are only WAGs. Now you know which routine was doing the overlaying - that gives you something definite to work on. Also, the inhouse program was overlaying storage area contents present in subpool 0 but the inhouse routine used was only sorting the contents present in subpool 1. Is it possible for a program to corrupt/ overlay contents present in different subpools? Look at MVS: Diagnosis for a description of subpools and storage keys. Also, you should register with the list server and send you mails to IBM-MAIN. You'll reach many more fine individuals that can help you in the future. -- John -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

The Line, the Bar, Java, LPA, etc.
Can 64-bit Java applications reside above the Bar? I'd assume they could provided they contain only interpreted code, not executable. Can 31-bit Java applications reside in LPA? I'd assume they could if LPA doesn't require that modules contain some executable code. The LOAD SVC could find the CSECT address for the interpreter; the saving of sharing frequently used modules could be significant. But, are some installations feeling the storage constraint of growth of LPA, even to the extent of needing to make uncomfortable decisions about what to exclude from LPA? There'd seem to be motivation here for supporting an above-the-bar extension of LPA. Why is the documentation of Java so sparse? Searching Elements and Features on Publibz for java returns a preponderance of hits in SMP/E manuals; man jar in Unix System Services returns not found. Is the Java doc somehow tied up by my employer?

I think he understands that; but I see him as asking the question: can the Java bytecode be loaded above the bar and the Java interpreter run the bytecode located thusly. It's an excellent question, and I'd be interested in getting the answer too: can the 64-bit JVM access bytecode stored above the bar? As such, it does not make sense (to me) to talk of having a Java application in LPA. Rephrase: can you load a CSECT only containing read-only data (which happens to be Java bytecode) in the LPA. However, I believe you could have the interpreter in LPA if you wanted. That's also a question of interest. (Though I will also admit I'm not an expert in that area.)

Re: The Line, the Bar, Java, LPA, etc.
True: A compiled Java application consists of .class files or .jar files (zip files) containing .class files. The .class files contain byte codes which can be interpreted by the Java virtual machine (JVM). But: all modern Java virtual machines includes a just-in-time (JIT) compiler, which dynamically translates byte codes for frequently used methods into native machine instructions. So, everyone who insists that Java is slow because it is interpreted look for other reasons :-) So, it is interesting to ask whether the machine-code created by JIT could be in LPA. The current JVM does not support this, since this machine code is dynamically created and not really shareable.

Re: my free mainframe product
HI, Thanks for your good question. As far I know Hercules can not make mirrors to real 3390 and can not backup real 3390 and can not emulate 3390 from real MF or from any emulation MF as I do and can not be used for real DR purpose. MFNetdisk can run on real MF and can work with real 3390 disk (IBM, EMC or HDS) but of course it can run under Hercules or under any MF emulations. Easily the product can also copy and sharing MFNetDisk emulated 3390 between Hercules and real MF and any emulated MF. Yes, you hear good you can share MFNetDisk emulated 3390 between any MF (Hercules, IBM etc...) and the MFNetDisk keep the data integrity as real 3390 keep data integrity when it is shared between real MF. please try the program and you will see that this product is totally different from Hercules. I love what Hercules does but this is a different product. The only feature which is the same as Hercules is the data location of the emulated 3390 disk which is in PC. I can promise you that if and when you try the product you will love it. I know that we the old MF people afraid to try PC in MF environment but this product is different.

Re: The Line, the Bar, Java, LPA, etc.
The 64-bit version of the Java SDKs use 64-bit LE Heap storage for the Java heap (which includes not only Java objects, but loaded class files). I'm not certain about JITed methods (executable instructions), but I would assume that they are below the bar, in the 31-bit LE Heap. This could be confirmed in a dump that included JIT'ed code.

Paul Gilmartin wrote: could. But would it happen? Is z/OS at any price a preferred instructional platform? How relevant to mainstream computer science is teaching students to code DD statements for CKD DASD when the view of many sophisticated readers of this list is that CKD should be superseded by FBA? In our case, it would have helped tremendously. A few years ago, our Computer Science (CS) chair and the chair of the College of Business Administration's Management Information Systems (CBA/MIS) departments both wanted to incorporate a few classes dealing with mainframes into their curricula. The CS chair wanted to do a systems programming and OS series that would give his students hands-on experience installing, configuring, and running multiple operating systems while teaching a lot about the underlying algorithms where they could compare and contrast them. He basically wanted some LPARs or (if we could get VM) some virtual machines on our mainframe (one for each project team). The Windows and UNIX portions of the course would be done on the students' own PCs running Windows and BSD. But they couldn't afford a mainframe so came to us to see if they could get time on our 9672. The CBA/MIS chair wanted to incorporate CICS/COBOL/DB2 programming into their curriculum to complement the stuff they do with Windows and UNIX. Our CIO turned them away because he was in the middle of a project to downsize our 9672 (our z890 is about half the capacity of our old 9672) so didn't have the spare capacity to offer ... part of our 5-year plan to phase out the mainframe ... that we started in 1990 ... but that's another story. Anyway, if an inexpensive way of giving our students access to their own z/OS environments were available, the University of Hawaii would be offering mainframe-oriented classes in two separate curricula today. Something like z/OS on Hercules on a Linux laptop would have fit the bill perfectly for us. Unfortunately, the opportunity was missed. The current chairs from those departments are not at all interested in offering mainframe components in their curricula -- they believe, as does our CIO, that mainframes are irrelevant. BTW: this year is supposed to be the last year for our mainframe (but somehow, I'm not convinced). Twenty years ago, I got a Macintosh SE, in large part so my girlfriend could write her doctoral dissertation in music. Would I have taken an s/370 (XA?) at the time for personal use?. Not if it were free; not if it were in a package I could carry. How many of us today, given a z/OS system that weighed 5 pounds and cost $1000 would make that our only computer and OS? Wouldn't we each still need another computer, or at least a partition on the same one, for Email, Web browsing, document preparation, access to IBMLink, etc.? *snip* If IBM can't make z/OS the only OS people need, and the first choice for many, too many customers will find it expedient to seek to use the computer and OS they already need and own to host the additional applications they come to need. Is it even plausible that enterprises seeking to simplify their IT structures by reducing the number of OSes they support would consider eliminating Windows, Linux, OS X, or Solaris and moving all its applications to z/OS? I think that's an extreme view. I don't think anybody is thinking of replacing Windows or MacOS or Linux on the desktop with z/OS. But why not z/OS as a back-end server? Even our CIO acknowledges that, while he would prefer that we only had Solaris/SPARC servers in our data center, it often does make sense to run other server operating systems. He believes that more than one but not more than 4 different server OSes is reasonable. And what I'd be interested in is running z/OS in a virtual machine under Linux on my laptop (I run Windows in a virtual machine on my laptop now just so that I can run the officially sanctioned applications that my organization requires us to run) so I can do development without worrying about hurting any of our LPARs on our z890. I think it would be great if students could get the ability to run z/OS on their laptops to learn about it. Anyway ...

I would ask what type of hardware is your SAN? I am running on 2 DMX3000 Storage Arrays by EMC. We share the box but not the disks with the open system folks. They have the SAN stuff. One storage array is the primary DASD that we normally run off of. The second is populated by EMC's Replication process and therefore all of the SYSRES data is constantly being updated on the second Storage Array incase the primary array fails. If it does, the EMC software will swap us up to the replicated string and we are still running. Coming back is more fun, as we use the Autoswap software to do that. We are always on Mainframe dasd never SAN. And as RS pointed out, the mainframe does not use SAN. We live on a DMX where SAN and mainframe share the box but not the disks.

Re: Curiousity question: the processing of DD DUMMY.
I've never questioned the path length or development costs to support both DDNAME and DSNAME options for a null file, i.e. DD DUMMY and DSN=NULLFILE, but as pointed out earlier in this thread, they are both ancient. The virtue of having both is the flexibility of choosing whichever one is more convenient (if either would work) or being able to use the function at all in a context where only one would work. The 'equivalent' examples quoted from the manual differ greatly in coding JCL statements in a cataloged procedure: DSNAME can be represented as a symbolic variable but DDNAME cannot. //UPDATE PROC IN1='APP.TRANSFILE' //INPUT1 DD DSN=IN1 At execution time, without touching the proc itself, one can run the program with null input with minimal coding. // EXEC UPDATE,IN1=NULLFILE Back in the day when resources were far more expensive than they are today, being able to test or diagnose or just validate with empty input or output files was crucial. It still makes sense today. I'm guessing that the 'unnatural' syntax option for a null path name simply gives a Unix user the same two choices as in MVS JCL. As a mainframer, I find the mechanism ingenious, not offensive. . .

I suppose that Unix community would expect the look and feel of Unix, even as the JCL community would expect the look and feel of JCL. -- gil --

Re: Curiousity question: the processing of DD DUMMY.
On Wed, 2 Jan 2008 16:56:19 -0800, Skip Robinson wrote: I've never questioned the path length or development costs to support both DDNAME and DSNAME options for a null file, i.e. DD DUMMY and DSN=NULLFILE, but as pointed out earlier in this thread, they are both ancient. The virtue of having both is the flexibility of choosing whichever one is more convenient (if either would work) or being able to use the function at all in a context where only one would work. I'm a little puzzled. In what context would DD DUMMY work where DSN=NULLFILE would work differently, or not at all? The 'equivalent' examples quoted from the manual differ greatly in coding JCL statements in a cataloged procedure: DSNAME can be represented as a symbolic variable but DDNAME cannot. ITYM the positional parameter DUMMY, not DDNAME. //UPDATE PROC IN1='APP.TRANSFILE' //INPUT1 DD DSN=IN1 At execution time, without touching the proc itself, one can run the program with null input with minimal coding. // EXEC UPDATE,IN1=NULLFILE One could equally well code: //UPDATE PROC KEYWORD='' //INPUT1 DD KEYWORD.DSN=APP.TRANSFILE And at execution time, without touching the proc itself, run the program with null input with minimal coding: // EXEC UPDATE,KEYWORD='DUMMY,' ... the constructs are highly equivalent in expressive power. Back in the day when resources were far more expensive than they are today, being able to test or diagnose or just validate with empty input or output files was crucial. It still makes sense today. Agreed. I'm guessing that the 'unnatural' syntax option for a null path name simply gives a Unix user the same two choices as in MVS JCL. As a mainframer, I find the mechanism ingenious, not offensive. A bad guess. The choices would exist regardless. There is need for the CI, and perhaps JES3 setup, to provide special handling for DSN=NULLFILE. Otherwise, there would be a default DISP=(NEW,DELETE) and the initiator would issue an exclusive ENQ for the name, preventing other users concurrent use of NULLFILE. No such concern applies to PATH='/dev/null', and the filesystem itself implements the character special device. The code and documentation to provide special handling for PATH='/dev/null' is unnecessary; therefore wasteful; therefore I find it offensive. Again, what is the benefit provided by the special treatment? What facility is provided by the allocation's (and perhaps the CI's) treating /dev/null differently from any other pathname? -- gil -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Re: my free mainframe product
I've been reading the notes for MFNETDISK for a while and it complements Hercules emulated disk as one of the functions. Unless I'm mistaken, the disk emulation would be useful where the disk is remotely located from the processor complex or emulated processor (Hercules etc.). Obviously performance would suffer depending on the available bandwidth for remote TCPIP transmission of IO but for an absolute DR capability, the product has many facets I can visualise. If a mainframe complex was taken out, the mirrored emulated disk could be distibruted across multiple locations on multiple PCs or just a single remote location. It might take some time to get your disk re-assembled into usable status but it would mean you have a fairly hot backup available ay any point in time. The product isn't actually much use on Hercules other than to test the functionality. To my knowledge, nobody is running modern o/s or TCPIP on Hercules since they can't be licensed. I don't believe there is a TCPIP for MVS 3.8, but I could be wrong here. Nice job, Shai. I hope you get some traction in the mainstream market.

Java is becoming the new Cobol
There is an interesting (???) thread in comp.lang.cobol that I thought some in IBM-MAIN want to look at. It does includes its the mainframe is just as dead as COBOL statements, but I still think that some in IBM-MAIN would be interested in the comments about Java, COBOL, and the mainframe. The article is not making the point that Java is becoming the corporate language of choice, as Cobol is/once was (choose one), but that is is becoming obsolete as it is being replaced by newer languages such as Ruby, PHP, AJAX [sic], and even C#. http://www.infoworld.com/article/07/12/28/52FE-underreported-java_1.html If you're a Java developer, now's the time to invest in new skills. There was a quote from a quarter century ago or more that went 10 years ago there were 3000 languages and COBOL, today there are 300 and COBOL. In 10 years time I expect there will be 30 and COBOL. The question then is: Is Java just another fad language in the range: Algol, Pascal, Modula2, Ada, C++, that will be replaced by the next fad languages Ruby, PHP, C# which will then be replaced by the next ... Or will Java really become the next Cobol and will continue for decades more ? -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Yes, TCP is a problem like the Hard disk in the past was a problem when try to use it in EMC, IBM and more to emulate 3390 disks but now everyone use Hardisk to do the emulation.

If you put every MFNetDisk PC device in remote PC distrubute all over the country then you might have a small problem but that is not true. The PC Devices can be in one or two PC Servers and then you have physical control on them. But do not forget that MVS have pointer (the parameters files) which points to all your PC and of course you can have backup of this file in another location MVS or another PC.

Restore the other tape to a disk volume. 7) IPL the disk volume Alan Altmark z/VM Development IBM -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: Java is becoming the new Cobol
I find it interesting how I interpreted the title of the article, Java is becoming the new Cobol. The meaning conveyed to me by the title was exactly opposite of what the article was about. To me Cobol means tried, true, and stands the test of time. -Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Bill Klein Sent: 3. tammikuuta 2008 8:10 To: IBM-MAIN@BAMA.UA.EDU Subject: Java is becoming the new Cobol There is an interesting (???) thread in comp.lang.cobol that I thought some in IBM-MAIN want to look at. It does includes its the mainframe is just as dead as COBOL statements, but I still think that some in IBM-MAIN would be interested in the comments about Java, COBOL, and the mainframe. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
JCL procedure parameters
A recent discussing in ASSEMBLER-LIST reminded me of something I tried to figure out a while ago (and didn't): Is is possible to somehow retrieve the JCL procedure parameters and their values in a program that's invoked in that procedure? I browsed the documentation of a large number of Jxxx and Sxxx control blocks but didn't find anything that suggested this was possible. Does anybody now if (and how) this could be done? Some background information: we use a utility that reads controls cards from a sequential datasets and replaces variables in the controlcards by values. The result is wriiten to an output file that can thren be used to control a program in the next jobstep. The variables and values are passed to the utility via EXEC PARM= as a series of field=value,field=value pairs. This allows you to stick JCL parameter values in the control card. The problem is the maximum size of the PARM= parameter that severy limits the number of variables and the length of the values. This could be fixed if the values wouldn't have to be passed via the PARM= parameter because the utility could somehow get directly to the current JCL parameters and their values Thanks for any input you can give, Fred! - ATTENTION: The information in this electronic mail message is private and confidential, and only intended for the addressee.

Re: The Line, the Bar, Java, LPA, etc.
Happy New Year to everybody! I'm not certain about JITed methods (executable instructions), but I would assume that they are below the bar, in the 31-bit LE Heap. This could be confirmed in a dump that included JIT'ed code. Since output from JIT are *executable* instructions, i.e. machine instructions, they cannot reside above the bar. z/OS does not currently support this. The code would die at the next interruption. -- Peter Hunkeler Credit Suisse -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: The Line, the Bar, Java, LPA, etc.
But: all modern Java virtual machines includes a just-in-time (JIT) compiler, which dynamically translates byte codes for frequently used methods into native machine instructions. So, everyone who insists that Java is slow because it is interpreted look for other reasons :-) The emphasis being on frequently, which means some hundred or thousand times, right? Before that it is interpreted and still a reason -- Peter Hunkeler Credit Suisse -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: IPL'ing from a SAN device
Lizette Koehler wrote: [...] We are always on Mainframe dasd never SAN. And as RS pointed out, the mainframe does not use SAN. We live on a DMX where SAN and mainframe share the box but not the disks. Lizette, R.S. claimed exactly contrary opinion. There are no non-SAN disks. In other words ALL mainframe disks are SAN-attached. OK, the answer was tricky and perverse a little bit. g But - what is a definition of SAN? Leaving history, BusTag channels, etc. - we have FICON channels connected through a switch (optional) to a DASD array. Exactly the same equipment and physical topology is needed for FCP. So, mainframe uses SAN, but usuallly not SCSI commands (with the exception for FCP). -- Radoslaw Skorupka Lodz, Poland -- BRE Bank SA ul.
