Re: TOD Sync acroos platforms (IBM and non-IBM) - STP?
Dave, If by processor you mean the sZeries CPC, then your understanding might be a little off... My understanding is that the timer just sends timing signals to the CPC, it is unaware of what the CPC is doing. Basically it is a one way process. Whether there is a CLO or not, the 9037 never gets the time from the CPCs. It just sends the time and stepping signals to control the CPC clock rate. (it also sends offsets for daylight saving/Leap seconds etc). The only thing the 9037 is aware of is that there is a CPC connected at the other end of the port. So long as there is a link established, then it doesn't know what the CPC is doing with the information. If your CPC is connected to 2 9037 ports, then both 9037 ports send data unaware as to which port is being used by the CPC. The only thing the 9037 knows about the CPC is how far away it is. It determines this so that it can tune the signal on each port to take account of time delay etc.. If there isn't a CLO card then you're right in that the clock on the 9037 processor board is used as the time source. However, if you have a CLO card (which is required when you hook up 2 timers), then I believe that internally to the 9037 it is the CLO card(s) that are used to maintain the clock and its steering rate. These use some sort of voltage controlled oscillator to maintain syncronisation with two timer units and to enable the clock rate to steer to a corrected time. Whether the corrected time is a manual input, or from an ETS, I don't think makes much difference to the CLO - it just steers the clock to the new time. Regards Roy Dave Kopischke wrote: And my understanding of the function of the timer is to steer the onboard clocks on the processor. The processor clocks are always the source of time information. The timer compares the time from the external source to the time on the processor and either slows the clock down or speeds it up until they match. If you don't have a CLO card, the timer itself is the time source (your wristwatch is probably more accurate). You can't get more than four seconds out of synch or the timer won't be able to generate the proper steering impulses to get the clocks back in synch.

FDR Compaktor - missing/reappearing data sets
we have run into an issue where compaktor is running on sys1 and df/dss is running data set backup's on sys2. what appears to happen is that when compaktor is working a volume that dss is backing up from, data sets go 'missing' unitl compaktor is done. the dss backup spits out an ADR321E data set not on volume but finds the data set when the backup job is resubmitted and compaktor has released the volume. The dss parms specifiy tol(enqF). We use GRS-star, do not globally convert all reserves, do have this coded RNLDEF RNL (CON) TYPE (GENERIC) QNAME (SYSVTOC) I suspect this is just a timing matter and the defrags shouldn't be running in the storage group where batch production is running, but thought I would ask if I'm may be missing anything in the RNL's or with Compaktor. -- 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

3490 mount POD display problem?
Our tape operators are saying that there are times when the flashing M on the 3490's display is not there. The volser is there, but without the flashing M, they believe that the tape is mounted. Has anybody else had this problem on z/OS 1.6? Apparently this is an intermittent problem, not a hard failure. But it does cause definate problems to them since they watch the 3490 displays more than the z/OS console. Oh, no hits that looked reasonable on IBMLink that I could find.

Is there a clock in the HMC, so the data path for that initial setting might be: ETR to HMC (at POR) HMC to TOD (at IPL)? The HMC is not used in any of the time setting process. Remember the HMC is purely optional, its only an operator aid, you can POR/IPL without it by using the Support Element (SE) (the Thinkpad inside the CPC). There is an option to sync the HMC time with the time on the SE As for the POR time, I suppose it depends on the CPC model in use. But with the latest zZeries it gets the TOD time from the 9037 - if you have one. If not, it gets the initial time from the Support Element at POR. That being said if you POR without a 9037, then connect one afterwards, it just gets on with life and uses the 9037 value. This I know as I recently did a lot of work with new CPCs and timers. The timer was connected after the POR and all was ok. Just to add to the loop the SE will sync to the CPC once a day With IPL time, each LPAR has its own virtual TOD clock that is initially set when the partition is activated. The initial value is usually that of the CPC TOD. If there is a 9037 and the Opsys supports it then it will use the 9037 time and can accept offset changes etc. The LPAR profile has options to enable the use of the 9037 and also to specify any offset value I recall we once got about 15 seconds out of sync, and were able to recover without the dreaded POR by repeatedly issuing manual commands to steer by a couple seconds until after about a week the ETR was within tolerance to sync to NIST dialup. I believe an IBM employee (Greg Dyck?) has supplied instructions for doing this on this list. Setting a new 9037 time to drift to can be a real pain due to the 4.999 seconds maximum value at a rate 1 sec per 12 hours - i had to adjust 45 secs recently.I never understood why this maximum value was so low. Then recently I saw some possible explanation for the low value. I was testing the 9037 ETS a few weeks back and for some reason, not sure why, the time that was interpreted from the dialup modem was way off, about 21 hours in advance. As this was over the maximum if ignored the value and disabled the ETS. I suppose a sensible approach. What would have been better would to have the 4.999 secs for ETS, but a manual offset greater than this could prompt for are you sure.

Re: WLM Question
The trouble with enclaves is that they can be very short lived things and catching the tiddlers with the SDSF or MXI ENC commands is a matter of luck or furious enter pressing. I don't think that SDSF ENC was available for OS/390 R10 - however I believe that the MXI ENC command will work (its been a while since I have tried it on that level of MVS). The programming interface to get enclave information is IWMRQRY and the information that this reports on is updated approximately every 0.25 of a second - WLM rather helpfully issues a system ENF event to tell listeners that new data is available to save them getting the same information twice.

Re: WLM Question
Terry, As was stated before, SDSF has the ENC or ENC ACTIVE displays for seeing what is currently going on, and RMF3 has the ENCL panel to look back through recent history (as far back as your datasets go). In regards to long-term reporting, we do overview tracking for DDF Enclaves by extensively using reporting classes. Each time a new DDF enclave classification is installed in WLM, we find out who the owner is, and add an appropriate report class to their qualification rule. We can track each business unit, and each DDF classification within that business unit, using RMF reports. Granted, this isn't a super-detailed level of reporting, it's much more of a summary/overview, but it will quickly tell us how each class of DDF transactions is performing and which SRVCLASS they found their way into.

Thanks for the response. Would like to avoid RYO for this. And I can well imagine it would be a hog. But, I don't really need this info continuously.

Gary, Thanks for the response. ENC is not available at our os level (2.10). I am in the process of getting RMF III running and will see if that helps.

That last comment is a little alarming! Our DDF traffic is 1/3 MS Access, 1/3 DB2 connect, and 1/3 locally developed java apps. Of the three, MS Access causes the most pain hands down.

How to marry subsystem and dynamic allocation
Good afternoon, IBM-MAIN We'd like to be able to prevent certain confidential fields in production files from being revealed to unauthorized users while still allowing access to the rest of the record. From the users prospective these files are read-only and are accessed through TSO, batch or CICS for testing or comparison purposes. The total volume of such files is huge and changes daily, so cloning them and altering the sensitive fields is not an option. The only other option we can think of is to develop an in-house method of intercepting and altering records while they are being read, transparently to the application.

Re: C on z/OS questions
The bracket problem is due to the ASCII/EBCDIC translation table used during the conversion, probably by ftp. If you can find (or create) a good table, you could retransmit the source properly. To call a C module from an assembler routine, you have to establish the proper environment. The Programming Guide manual has a whole section on inter-language calls. I don'tknow if COBOL already sets up a suitable environment. If not, you could create a short assembler routine that could be called from either to perform the setup. There is no need for main in a particular source module. I've compile many source files that don't contain main. (If you are building a C program, then there must be a function called main in exactly one source module that will eventually be linked into the program.) What compiler message are you getting that makes you think you need main? I don't use DLLs but I thought I saw traffic here previously that Binder can build them. john stephens [EMAIL PROTECTED] wrote: Hey all, I have recently inhereted an application that was written in C on a Win32 / AIX platform that needs to be moved up to the mainframe (z/OS V1R4.0).

Re: How to marry subsystem and dynamic allocation
Hi Victor, This is probably the answer you have considered and rejected. If you require field level security for this production data you need to get that data moved out of sequential or VSAM files and into a DBMS like DB2. DB2 provides the granular security and encryption you require. The time to develop and support the subsystem you are proposing even if it is technically possible is going to be cost prohibitive to any commercial concern. Migration of the data to a DBMS will have benefits well beyond providing the multilevel security access you require.

Re: Putty connection to mainframe
Others have correctly observed that PUTTY does not emulate a 3270. What is the real requirement? Is it to encrypt all tn3270 traffic between your workstation and your mainframe? PUTTY can encrypt vanilla telnet to a unix box - maybe the real requirement is to do SSL for your tn3270 traffic.

Re: I/O Retries
We finally took some steps to attack this problem on the processor that showed the highest I/O retry count. - During the week, the CE removed all unused ESCON cards on one processor. (Nondisruptive) - On the monthly IPL weekend, we brought down all LPARs on the processor. - We did two PORs: first with the previous IOCDS, then with the current IOCDS. The double POR was advised by the CE in order to force redistribution of the SAPs across remaining chpids. Otherwise a minimal POR with the same IOCDS would not necessarily reassign SAPs. The result is heartening but a trifle puzzling. RMF still reports unbalanced SAP usage, with one being used conspicuously less than the others. But the real problem--excessive I/O retries--appears to be fixed. The count is not zero but far lower than it was before the exercise. . .

Assuming that the numbers are being reported correctly, does anyone have a notion of what might cause this anomaly? Some facts: - Reports do not detail the I/Os being retried by channel or device; just a total number - No channel looks excessively busy according to RMF - We see this on more than one CEC (all z900) - SAP/IOP processors are 'unbalanced' This last point might be an issue. We have a fairly large number of now unused ESCON channels whose function has moved over to FICON. It appears that the three SAPs divide up all channels among themselves, but one of them--which happens to have the most idle channels--is less than half as busy as the other two.

Re: Problem copying VM volumes under z/OS
A VM volume can be formatted two ways: * if initialized using the CPFMTXA (which actually invokes ICKDSF INIT CPFORMAT) it contains a dummy MVS VTOC on cylinder 0, track 0 starting on record 5. This is not a natural location for a VTOC, but it does allow the volume to be mounted on MVS. This VTOC never has datasets in it and shows no free space on the volume. Products like FDR and DFSMSdss recognize this dummy VTOC and know that it is VM-formatted * but you can also initialize the volume with standard ICKDSF INIT, which puts a real VTOC on the volume. Since by default it puts a small VTOC on cyl 0, track 1, and VM mini-disks are generally allocated starting on cylinder 1, this will work for VM, but MVS will see it is an empty volume. So you must have case 2. The only way to copy these under MVS is to use the COPY TRACKS function of DFSMSdss, specifying the whole size of the volume. It is possible to reformat the VTOC without disturbing the data, but I don't know VM well enough to tell you how -- Bruce Black Senior Software Developer Innovation Data Processing -- 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: Data conversion from 3380 to 3390 - H E L P
Clearly the biggest issue is the geometry change from 47K to 56K; so you can’t use any “physical” type utilities (E.g. Full Dump Restore) to perform the data move unless you configure the 3390 devices in 3380 emulation mode. Ya know, that is not completely true. As long as the output track will hold all the records on the input track, most access methods will support a track-by-track copy. VSAM usually will not, but does in some circumstances. PO datasets are an issue because one of the quirky differences between 3380 and 3390 is that the 3380 holds 1 more PDS directory block on a track than the 3390. So if the 3380 PDS has more than 1 track of directory (47 blocks I believe), then the track copy will fail -- Bruce Black Senior Software Developer Innovation Data Processing -- 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: FDR Compaktor - missing/reappearing data sets
we have run into an issue where compaktor is running on sys1 and df/dss is running data set backup's on sys2. what appears to happen is that when compaktor is working a volume that dss is backing up from, data sets go 'missing' unitl compaktor is done. the dss backup spits out an ADR321E data set not on volume but finds the data set when the backup job is resubmitted and compaktor has released the volume. The dss parms specifiy tol(enqF). We use GRS-star, do not globally convert all reserves, do have this coded RNLDEF RNL (CON) TYPE (GENERIC) QNAME (SYSVTOC) I suspect this is just a timing matter and the defrags shouldn't be running in the storage group where batch production is running, but thought I would ask if I'm may be missing anything in the RNL's or with Compaktor. Jerry, as others said, please call us with question, any time. What is happening: during the COMPAKTion, CPK protects the datasets selected for movement by changing the last character in the dataset name to lower case.

Re: How to marry subsystem and dynamic allocation
On Thu, 23 Mar 2006 15:13:57 -0500, Gil, Victor x28091 wrote: Good afternoon, IBM-MAIN We'd like to be able to prevent certain confidential fields in production files from being revealed to unauthorized users while still allowing access to the rest of the record. From the users prospective these files are read-only and are accessed through TSO, batch or CICS for testing or comparison purposes. The total volume of such files is huge and changes daily, so cloning them and altering the sensitive fields is not an option. The only other option we can think of is to develop an in-house method of intercepting and altering records while they are being read, transparently to the application. Here's what we've researched so far: - In CICS this should be easily achievable through the file control exit. The exit would look up the dataset in a table and if found, apply a correspondent rule. - In batch we would implement a subsystem that would intercept each [sequential] I/O and alter the record using the very same rules. What do we do in TSO? Generally, how do we intercept records of a dynamically allocated file? There is a system-wide dynalloc input validation exit, IEFDB401, and it might be able to add SUBSYS=... to the DYNALLOC requests, but this would severe overtax all other dynamic allocations in the shop. Appreciate all and any ideas, as crazy as they might sound -Victor- Victor, I wonder just how huge the total volume of files really is. (Are we talking trillions of bytes? Tens-of-thousands of files accessed daily?) Why not consider splitting these files into a confidential and non- confidential file pair? The advantage of splitting the files into a confidential field file and a non-confidential field file is obvious: security should be straightforward. You could stitch the common I/O routine into the GET routine address via a subsystem (as you've suggested) or via an OPEN front-end (as, I believe, John suggested), or via a BatchPipes stage (e.g., JOIN). The BP subsystem approach could be used to stitch the files together on reads and split them apart on writes. BP with appropriate fittings should be able to accomplish both of those things with a comparitively minimal amount of programming on your part. The BP pipelines stages would not necessarily require a pipe writer + reader pair of jobs; you would use the pipe fitting SUBSYS JCL to insert the stages onto the DD statement(s) and avoid writing nearly all of that nasty authorized code to filter your confidential (and no-doubt customer critical) files. The issue I'm largely ignoring is getting the JCL inserted... but that might be fairly simple with some unique pipe stages to perform dynamic allocation (although you might have problems doing DYNALLOC at some points in the processes). (I don't recall ever trying to do that w/ BP.) It might require JCL changes but mass JCL changes aren't much of a challenge. (Besides, if your users need access to the secret stuff they'll go along with the change.) But these confidential fields -- won't programs that don't get to see them miss them in the records at all?

Re: Putty connection to mainframe
His real requirement is to placate the management/network/security folks, but they just don't know how to phase their demand in IBM mainframese. They probably really want to stop cleartext userid/password transmission where all the spies can see them. They network and security folks know that ssh is the protocol for encrypted terminal sessions for unix (the only real opsys in their world) and know that putty is a very good ssh program on the Windows desktops that management makes them use. Therefore when they want the mainframers to stop sending userid/password in cleartext, they tell you to use putty. They are right. Just nod your head, say sure and go turn on SSL protected TN3270 services on the TELNETS port 992. That way the network people can check their list of well-known ports and see that you really are doing what they meant to say. The x3270 and c3270 programs as packaged by Mike Caughran from State of Alaska supports SSL encryption. To turn this on, enter the connection address as L:ipaddr/name:port, such as L:vm1.hqadmin.doe.gov:992 and you will have a nice cheap secure tn3270 emulator and your management/network/security people will be satisfied. /Tom Kern --- Brian Peterson [EMAIL PROTECTED] wrote: Others have correctly observed that PUTTY does not emulate a 3270.

Re: Compare z900, z890/z990, z9
Looking for a comparison between all the z/Boxen with regard to: 1. Sub-capacity licensing availability / support, Supported on all the systems you named (as long as you meet the other requirements). It's worth noting that z800 and z890 have fractional engine configurations available to fine tune capacity a little more precisely than their bigger cousins. 2. Turbo vs non-Turbo: What it means, where/when it applies, etc. Turbo just means a faster engine, and I think it only applies to the z900 out of the models you listed. The z900 got a mid-life engine boost before the z990 came out. The turbo models start with a 2 in the three digit code. For example, a 2064-105 is a non-turbo model (with 5 main processors). A 2064-211 is a turbo model (with 11 main processors). Here's how the model numbers look: z900: 2064-1xx z900 Turbo: 2064-2xx z800: 2066-xxx z990: 2084-xxx z890: 2086-xxx z9-109: 2094-xxx The xxx reflects the capacity for each system (for main processors). 3. Capacity models: meaning, applicability. Hmmm... Not sure (other than above). Any more context where you heard/saw the term? More information... 4. MSUs (main processor capacity rating) decline 10% for the same transactional capacity with each new generation system. For example, a hypothetical z900 rated at 100 MSUs of capacity would have the same performance as a z990 rated at 90 MSUs. (In practice the numbers don't line up this neatly due lumpy capacity increments and variations in real workload, but the underlying math is correct.) Most z/OS software is charged according to the MSU rating. This 10% curve is called the technology dividend. Here's how the mainframe generations look (using 100 as a hypothetical base): z900/z900 Turbo/z800: 100 z990/z890: 90 z9-109: 81 Said another way, the newer your mainframe the more processing you can do for the same software budget. (Or the same processing you can do for a smaller software budget.) 5. There are more (and faster) specialty engines as the systems get newer. Here's what's available by model grouping: z900/z900 Turbo/z800: IFLs and ICFs z990/z890: IFLs, ICFs, and zAAPs z9-109: IFLs, ICFs, zAAPs, and zIIPs Cryptographic processing also gets better and faster the newer the model. The specialty engines can offload work from main engines, allowing either more main processor efficiencies (and lower costs) or the addition of more work to the mainframe (for the same costs), or some combination of both. And these last few points are the important bits because they imply something very real about mainframe economics: add more work to your mainframe and your per-transaction processing costs go down (and often quite dramatically). Take work off and your per-transaction processing costs go up. It's like owning a truck: it costs very, very little to send the truck on another trip. You still have to buy the truck, insure it, keep a back office to support it, etc. Which leads me to some final words about the mainframe cost paradox. How can you make mainframes cheaper?

Re: WLM Question
Terry Linsley writes: Our DDF traffic is 1/3 MS Access, 1/3 DB2 connect, and 1/3 locally developed java apps. Of the three, MS Access causes the most pain hands down. Off on a slight tangent here, there are some things you can do to take the DDF temperature down. I'll list these in order of timeliness to your current situation -- first what's possible with OS/390 V2R10, then moving beyond. (As it happens the OS/390 options are reusable and apply to z/OS, so there's no danger of throwaway effort.) OS/390 Possibilities: 1. Put DB2 Connect on Linux on the mainframe. Having a local connection between DB2 Connect and DB2 (even if it isn't a Hipersocket) should shave some milliseconds out of each connection, and that'll help DB2 work more efficiently. Try sending your Microsoft Access and Java clients in via this DB2 Connect on mainframe Linux and see how that works, too. 2. Move some/all of your Java applications (particularly the data intensive ones) up to mainframe Linux. Same principle as #1: proximity has workload benefits. z/OS Possibilities: 3. Add a Hipersocket between DB2 Connect (mainframe Linux) and DB2. Requires z/OS 1.2 or higher and z900 or higher. 4. Evaluate DB2 V8 to see whether you have requests that could benefit from multi-row fetch/multi-row insert. Microsoft Access might very well be in that category. Requires z/OS 1.3 or higher and z900 or higher. (Combine with DB2 Connect for Linux on mainframe.) 5. Add a zAAP and move the Java applications into the same LPAR as DB2. (The most proximate solution.) Requires z990, z890, or System z9. Requires z/OS 1.6 or higher. 6. Add a zIIP for the remaining inbound traffic arriving from outside the LPAR. Requires z/OS 1.6 or higher, DB2 V8, and System z9. This option becomes available later in 2006. Hope that helps! - - - - - Timothy F.
