Re: HSM Missing Member from Recalled Dataset -- Update
Background: Over the Thanksgiving holiday weekend (U.S.) we relocated our datacenter. We moved the mainframes' DASD volumes via DFSMSdss DUMP FULL at the old site, followed by RESTORE FULL at the new site. On the day the DUMP FULL of every volume was taken, a TSO user had recalled a migrated PDS and created and saved a new member therein. At the new site, following the RESTORE FULL of every volume and after the TSO user's PDS had once again been migrated by DFSMShsm, the user recalled the PDS, and noticed the new member he had added was missing. We had previously configured DFSMShsm for Fast Subsequent Migration (FSM), and we had specified this user's datasets as eligible for FSM. Timeline: Day 0 (Old site): 1. TSO user HRECALLs PDS on Development LPAR; creates and saves new member. 2. z/OS (1.5) on Development LPAR is shut down before DFSMShsm automatic backups run, and DFSMSdss DUMP FULL is started for that LPAR's DASD volumes from sandbox z/OS (1.5) LPAR in the Sysplex. (Process was repeated for the Production LPAR later the same day, including suspension of DFSMShsm automatic backups.) Day 1 (new site): DFSMSdss RESTORE FULL is completed for all DASD volumes belonging to Development and Production LPARs (sandbox had been moved the previous week). Days 1 - 3 (new site): Verification / acceptance testing of the move is completed. The aforementioned TSO user did NOT participate in that testing. Day 4 (new site): Primary retention period for the TSO user's PDS expires. DFSMShsm decides that the PDS has not been changed since its last-known (to DFSMShsm) backup, so performs FSM, reconnecting the PDS to its previous (now stale) ML1 copy. Day 5 (new site, now in production): TSO user again HRECALLs the PDS and discovers the member added on Day 0 is missing. We were able to recover the correct copy of the PDS from the full-volume DUMP. I opened a PMR with DFSMShsm Support to try to determine why the PDS at the new site was missing the member added at the old site, and learned (among other things) that DFSMShsm relied in part on the setting of the change bit in the Format 1 DSCB to decide whether to reconnect (FSM) a migrating dataset to its previous ML1 copy, or create a fresh ML1 copy. We and they ran a few tests, and observed that the change bit was off in the DSCB for the dataset on the new volume after the DFSMSdss RESTORE FULL. Indeed, we observed that **EVERY** change bit in **EVERY** Format 1 DSCB on the target volume was off after a RESTORE FULL, regardless their settings on the source volume. The PMR was handed off to DFSMSdss Support, who later confirmed that RESTORE FULL does indeed unconditionally reset **EVERY** change bit on the target volume, and that it does so **by design** because the DUMP FULL tape is by definition, a backup of each dataset on the source volume. I noted that this behavior is both counter-intuitive and UNDOCUMENTED anywhere in the DFSMSdss literature, and requested that they reconsider this design point, at least in regard to RESTORE FULL. They offered instead to open a DOC APAR to fully document the RESTORE FULL behavior, and take a Marketing Request to offer a keyword switch on RESTORE FULL by which the end user could specify whether to reset the change bits. I've accepted both offers. Additionally, I've initiated a SHARE Requirement (SSMVSS07002, currently open for voting) requesting the original design change for RESTORE FULL along with full documentation of the behavior regarding the change bits. Please read, consider and vote on SSMVSS07002. -jc- -- 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

Less trouble. If no split can occur, does it mean that I cannot add keys to the middle but only in the sorted order? Or only that another processes are not aware about, therefore DISP=OLD. Meaning only one process can open the cluster simultaneously. It's acceptable for me that only one process opens the cluster but I prefer a distributed owning, where each server performs (ENQ anything DEQ ). But which anything is possible (DISP=OLD seems to mean - empty)? This is a difficult scenario and one with which I am not very conversant. My usual response here to somebody who want this is to point them to the books and tell them Good Luck! You'll need it!!! and also tell them that when their file is destroyed, it is THEIR problem, not MINE. In other words, I regard this as a very difficult thing to do correctly and I know that I don't know enough to make it work myself. No CI or CA split means just that.

Re: Memory Allocation for JAVA under USS
You can use the getrlimit service to increase the region limit up to the hard limit, which IIRC is set from BPXPRM00 or the user profile. There is an example of invoking this from REXX at http://members.tripod.com/billlalonde/rexx/setrlim.txt So you would invoke that with setrlim rlimit_as 2 (e.g.) You can use http://members.tripod.com/billlalonde/rexx/getrlim.txt to see the soft hard limits. Once the soft limit is set, that will be propagated to child processes. This may not apply in your case but, just for the record, IEFUSI should not interfere with region limits for OMVS work.

I then made them available to Netbeans via the Library Manager in Netbeans. In particular, the ibmjzos.jar, recjava.jar, and recordio.jar files. I would guess that many may use the Eclipse based WD4z. This is a more seamless environment for development. You pays for what you gets!

Re: Memory Allocation for JAVA under USS
Welcome to the brave new world. This stuff is *very* memory intensive. Start thinking orders of magnitude bigger. Once upon a time, K was big. Then meg. Now, gig is peanuts. Some may argue differently, but I submit that constraining main storage is just a superstition left over from the bad old days. Jack up your aux storage using cheap DASD, see to your stand alone dumps (again, cheap DASD), and let the roof blow off. See if you can drive your total system paging up to a few pages per second. A demand page fault now and then is not such a bad thing any more. In fact, some say it is a sign of health in that main storage is not just sitting there unused. Some argue that modern DASD is *so* blistering fast that a shop might find serious performance benefits with paging rates in the low teens. YMMV. Rather than constrain the resource, exploit it.

Early in January Russ Witt sent the list a warning about the implications apar OA17011 could have on tape retention. We've had some discussions about this apar internally; not concerning the technical impact but the fact that there was no hold on it. I'm not suggesting that it should have a hold but that, perhaps because of our methodology, if it weren't for Russ' warning we wouldn't have known about it. So I'm asking the group when you're applying preventative maintenance do you read and analyze the cover information for every ptf being applied?

So, I'm on ShopZseries ordering other updates, and see IBM Ported Tools for z/OS: Perl for z/OS. So I order it, thinking it is separate. I try to receive it, but it has the same FMID in the order as the standard Ported Tools. So, then I look at the announcement: http://www-306.ibm.com/common/ssi/fcgi-bin/ssialias?infotype=ddsubtype= smappname=ShopzSerieshtmlfid=897/ENUS5655-M23 And note the fine print: When IBM Ported Tools for z/OS: Perl for z/OS Feature is ordered, it will be sent with IBM Ported Tools for z/OS (which contains the OpenSSH function). An order of IBM Ported Tools for z/OS will not include Perl for z/OS Feature. OpenSSH and Perl for z/OS functions can be run independently. Guess which one I had ordered in the ServerPac Just the ported tools for z/os. So I've got ssh, but no perl(as far as I can tell from the announcement). So I order the one with perl, and try to receive it, and it has the same fmid(HOS1110) as the standard Ported Tools, yet I display it on shopz, and it shows a different fmid(HPRL110).

Re: KSDS immedial write
Keep in mind that your application will be dreadfully slow and simply will not scale. Even with modern DASD with response times in the sub millisecond range. Consider that each logical write may drive several physical operations. Ask your DASD czar what the unit response times are, and do the math. Just picking numbers out of the air: suppose that one 'transaction' drives four I/O operations. Each of those drives five alternate index operations. That's 20 synchronous I/O's. (Just guessing about the numbers. One write to a KSDS would include the target record plus the index record. There may be a couple more operations updating various pointers within the cluster. Each AIX would carry its own overhead.) DASD performance numbers are an average. You can achieve sub millisecond response times only with very aggressive buffering and caching. Without such, you might reasonably expect times in the half second range. It might be hard to explain a ten second response time to the average user. Not to mention an absolute cap of six transactions per minute. Things get exponentially worse as you add users. So, IMNSHO, synchronous I/O is not a good way to win the hearts of your users and please your management.

REXX APIs (Wanted: SMP/E)
While the topic of REXX APIs has resurfaced, I'd like to add an observation and a couple wishes: It's possible, with some planning, to design a CALLable API to be REXX-friendly. ICSF is an example. The chief requirement is that all control blocks and communication areas be passed to the API as parameters on each call, since Rexx can not conveniently generate pointers to obtained STORAGE. An alternative is that the API allocate all communications areas and return pointers to them in a single control block so that the Rexx program can manipulate them with STORAGE() So, the wishes: o The SMP/E API is Rexx-hostile. I've looked it over and used it from C, but it has a hierarchy of control blocks with pointers and it's not practical from Rexx. I'd like either a redesigned Rexx-friendly API, or an interlayer in another language that could manage the storage for Rexx. o Performance. As I see the ICSF interface, it must do a LINK or ATTACH for each call from Rexx, probably leading to numerous LOADs and DELETEs, even in tight loops. This may not be too onerous if the subroutine is LPA-resident. But it would be nice if Rexx had functions to LOAD at least REUSable load modules for multiple CALLs, and delete them when done, either electively or automatically in termination code. But that's a strictly Rexx issue, and could largely be handled by users (CBT tape, perhaps) -- gil -- StorageTek INFORMATION made POWERFUL -- 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: tn3270e server
We have used this feature starting on z/OS R6 and it has worked well for us. It is the recommended configuration. The Communications Server folks have been good about providing plenty of encouragement and warning to remove obsolete parameters and leverage features that are recommended that will become required. TN3270E seems like something you want to do before you have to. From the z/OS R9 Preview Prior to z/OS V1.6, the TN3270E Telnet server runs as a subtask of the TCPIP address space. In z/OS V1.6 through z/OS V1.8, users can run the TN3270E Telnet server as a separately started address space from TCPIP, or continue to run the TN3270E Telnet server as a subtask of the TCPIP address space. In z/OS V1.9, the TN3270E Telnet server is planned to be supported only when run in its own address space. Our network team has some automation that does a D TCPIP,TN3270E,TELNET,CONN command every 30 minutes so they can see the utilization. If I remember correctly we also had to raise MAXSOCKETS for INET in our environment. In general watch out for USS limits that might impact you in TCP/IP.

I agree with you fully Mark. My point was we both would have missed the ptf. And for the icing on the cake the ptf (in my case UA28410) was superseded by another ptf (UA90306). The newer one does have a DOC hold and some IPL holds but nothing in the ptf would lead you to be concerned about tape retention and SMS.

Re: Data Spaces or Hiperspaces
I have no experience with Hiperspaces, but have coded data spaces on a number of occasions. If you're going to play by the rules, the data space is tied to the address space that creates it, so if you do this, you have to keep the address space that does the create around.

Thanks, Tom Savor Playing by the rules means that the data space is deleted automatically when the owning task terminates. This usually means at end of job step all data spaces created by the application are gone. If your application is running authorized (supervisor state key zero), then you can create a data space and hang it onto a higher level task in the address space.

Hiperspaces are usually used for windowing onto the files (VSAM?), but I don't recall at the moment the gory details. If you want data persistence across job steps or jobs, then you want a data set and probably want to use a hiperspace for a window onto the file. Jeffrey D.

Re: z/OS V1R8 WLM CICS Performance Observation
I agree with Steve (a typical occurrence), more info is needed. At z/OS 1.7, did you routinely see your processor at 100% busy? What about the other LPARs on the box (if there are any)? Weights properly set? The reason for this line of questioning: if you were routinely running just under 100% at z/OS 1.7, when you went to 1.8, your overhead went up 2% to 3% to 5% (your mileage will vary). Once the CPU busy gets to 100%, WLM will now kick in. Once the entire CEC goes to 100% busy, PR/SM will kick in. An non-optimal WLM Service Policy along with improper LPAR controls may be tolerated at 95% busy; but once over 100% may cause you pain. Are you running on a uni-Processor? This also has challenges. So other input needed: Physical Config, Logical Config, WLM Service Policy (helpful), Perf Index for problem Service Class Period(s), what else is running in the system (above your problem CICS) Without more info, I'd suggest it is NOT a CICS problem (unless you also upgraded CICS or added maintenance). -Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Steve Samson Sent: Tuesday, February 27, 2007 SYSN PM 1:31 To: IBM-MAIN@BAMA.UA.EDU Subject: Re: z/OS V1R8 WLM CICS Performance Observation Jim, There's not enough information yet.

adTo save a mainframe
[Darren has told me it's OK to occasionally publish this kind of post; members of my opt-in list got the information a week ago, including pricing details; I have omitted prices here; if you are interested, please drop me a line off-list, or give me a call. ] If any of you have, or know of, a customer who wants to keep their z/OS system, but is being forced to move off the mainframe, here is a possible program to forestall that migration. The idea is to run a website from the z/OS system without WebSphere (that can be added later when those capabilities are needed), without having to install Java, and developed by their current z/OS applications programmers. z/OS is still a viable platform [I hope and believe]. And training is part of the tonic to revitalize it. So here's my latest offering. FastPath to z/OS-hosted Web Sites Host a Web site on your z/OS platform, without buying WebSphere. Use your existing COBOL (or PL/I or Assembler) programmers to develop and maintain a web site on your z/OS system (no need to hire new staff). In just 10 days (instead of 26 days) we can train a dozen or so of your z/OS developers (or a small, select team) how to do this! For a one time charge, with some special benefits (read on). To implement the FastPath approach, we have extracted just the essential courses needed to bring experienced z/OS developers up to speed. In 10 days (two weeks) we would teach this sequence of courses: * Introduction to z/OS UNIX * You and z/OS and The World Wide Web * Introduction to CGIs on z/OS * one of our language-specific CGI writing courses (COBOL, PL/I, Assembler, or REXX) What the students will learn: + How to run under the z/OS UNIX shell (omvs) + The UNIX HFS file system + Environment variables: what they are, how to use + 50+ UNIX commands + Copying files between HFS and classic MVS formats + oedit, obrowse, and ishell + How to access HFS files from non-UNIX apps + ISPF 3.17, the UNIX Directory List utitlity (z/OS 1.8+) + Basic flow of data on the Web + Building a web site on z/OS UNIX + HTML and XHTML - extensive, standards based + X/HTML style: attributes, elements, style sheets + CSS (Cascading Style Sheets) + Client side maps + Embedding multimedia + JavaScript - solid, practical introduction + DOM - the Document Object Model - solid, practical intro. + Forms and controls + Frames and Framesets + Creating and using cookies + Writing and using CGI programs (COBOL, PL/I, Assembler, or REXX) which is enough to create an interesting web site, running under z/OS, which can serve static pages as well as dynamically build and serve web pages using CGI technology. Note also that many of these skills are transferable to other UNIX and Web-related environments. Price is _all inclusive_: * Tuitions for up to 16 students * Instructor travel and living Student materials: * We ship you pdf files, you do the printing * AND you get to keep the pdf files for the print masters! (over 1200 pages of content) (but no instructor notes nor lecture versions) Option: two sets of sessions (total four weeks) * Two offerings run in parallel (morning afternoon) * Train twice as many people for less than twice the price * All students can work half days and be in class half days Here's a chance to give the technology a trial run at a very reasonable price and low investment of time. z/OS: not just for batch, CICS, and IMS any more. What's missing? Well, to get all the details, bells, and whistles, students would normally take a much fuller curriculum; for the FastPath we have chosen the central courses that students can use to build on, copying and modifying code to meet their needs. The fuller curriculum provides deeper and wider coverage of the underlying skills. Any FastPath student who feels they need more in-depth information can always go back to specific courses in the full curriculum as needed. The standard, full curriculum would be something like this: * Using LE Services in z/OS - 3 days * Language specific updates (Enterprise COBOL, HLASM 1.5, etc.) (2-4 days, depending on language) * Secrets of Inter-Language Communication in z/OS (w/ DLLs) - 3.5 days * Introduction to z/OS UNIX - 3 days * Shell script programming in z/OS UNIX - 3 days * You and z/OS and the World Wide Web - 5 days * Developing Applications for z/O UNIX - 3 days * Introduction to CGIs in z/OS - 1 day * Language-specific CGI courses - 1 day each -Steve Comstock The Trainer's Friend, Inc. 303-393-8716 http://www.trainersfriend.com -- to be included in our opt-in list of announcements of -- new courses and other products and services from The -- Trainer's Friend, send an email to [EMAIL PROTECTED] -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN

It also requires careful planning because things like multi-record type files should be converted into separate tables, 1 for each record type.
