Re: Data-in-Virtual Performance
[EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED]... We are using VSAM Linear datasets (LDS) and Data-in-Virtual (DIV) within our application and this is working fine - apart from under one circumstance. If we define a VSAM LDS as multi-volulme and capable of over 4GB by setting the Extended-Addressability option we can see some very severe throughput problems when the actual LDS starts using the 2nd and subsequent Data Volumes. STROBE shows that there is a big long I/O chain that seems to indicate that the underlying I/O is doing sequential reads from the start of each new volume - this in turn causes severe delays to the application. We have seen our application wiz through the first DASD volume and then go into a cycle of wait nearly 2 minutes, wake up and do a small bit of activity and then go to sleep again. Over a period of 4+ hours our application used 1.5 minutes of CPU time. The final dataset was written ok, it took just far far too long to deliver. We are sure that it is NOT our application code and that it must be something to do with DIV and its underlying I/O. Has any ever seen anything like this and has some advice/feedback to share? Thanks, Steve Steve, This sounds a little like a problem we discovered with Bookmanager. It appears to be an FSEEK() LE problem with multivolume datasets. On a single volume dataset, performance is good, on a multivolume dataset performance is terrible. The APAR number is PK50785. We received some fixes, but they did not fully solve the problem, just improved performance somewhat. Maybe this helps.

Re: Peer-to-Peer VTS and IBM ATL Specialist
Michael Pratt [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED]... Hi, We have recently implemented a Peer to Peer VTS solution, and are seeing some interesting 'anomalies' when looking at the copy queue from the IBM ATL Specialist software. Some volumes seem to enter the copy queue and are processed almost immediately - others seem to 'sit' there for eternity before being processed. Please note that this is not related to the use of the 'Immediate' or 'Deferred' PTP options - simply the time volumes spend on the copy queue.

Re: RMM - Problems with special EXPDT and VRS
Alex, In order to get those special EXPDT values to be honoured, you have to
handle existing data set, and also newly created data sets.
The conversion program, EDGCDYNM, for TLMS conversion handles the existing
data sets when the SYSIN option keyword VRSMGMTP PREFIX=ppp is
specified. The sample JCL codes VRSMGMTP PREFIX=D. What this does is to
set the VRS management value for each data set that used a special EXPDT;
in your example 99010 would cause D99010 to be set. Also a K record is
created for the D99010 VRS management value. You can check this has
happened by listing the data set and the VRS in RMM CDS after conversion.
Prior to running EDGHSKP VRSEL you should be able to see the VRS MV D99010
set for the data set - and the matching VRS information not yet set. You
should be able to list the VRS (RMM LS DSN('D99010')).
For new data sets created after conversion, it is EDGUX100 that must set the
VRS MV. The EDGUX100 sample exit supports only 99000 and 98000 special
EXPDT values, unless you customize it. However, there is a 2nd sample of
EDGUX100, but it is called EDGCVRSX; this is documented in the conversion
documentation (EDGCMM01 in SAMPLIB). It will handle all the special EXPDT
dates you need, but a table must be built for each special date you want to
use. It also provides ways for overriding special dates. If you have not used
this sample, that is likely your problem. EDGCMM01 does describe how to use
EDGCVRSX along with a sample table, EDGCVRST, however it does not provide
help in building a table. What you could do is use EDGCSRDS ( a CA-1
conversion program), but with RDS and TMSPARM DDs set to DUMMY, and
include the special dates in the VRSVALUE DD like this example;
//VRSVALUE DD *
99010D99010
For each one you specify, EDGCSRDS creates an entry for the ux100 table
(VRSTABLE DD), and a K record in DEXTOUT DD - some of the latter may
duplicate others created by EDGCDYNM.
Use the documentation in EDGCMM01 for CA-1 conversion about 'UXTABLE' to
see how to make use of this.
Once VRSEL is run, you should be able to see matching VRS information for
existing and new data sets that use special EXPDT values.

Re: z/OS using a guest virtual LAN under z/VM
Malcolm There's something a bit fishy here! Making the DEVICE name the same as the TRLE name does *not* correspond to what I just posted on the IBMTCP-L list concerning the relationship between the TRLE statement and the DEVICE statement. Thus I was obliged actually to go to the manuals where I find the following: From the CS IP Configuration Reference: quote DEVice device_name MPCIPA NONRouter PRIRouter SECRouter NOAUTORestart AUTORestart ... device_name The name of the device. The device name must be the PORT name of the LAN adapter defined in a TRLE for a QDIO connection. The maximum length is eight characters. /quote I'll admit that's a bit ambiguous. What's a PORT name when it's at home? From The CS SNA Resource Definition Reference: quote PORTNAME=(port_name,link_num) Dependency: OSA port operating in either ATM native mode or in QDIO mode. Specify link_num only for an OSA-Express port operating in QDIO mode customized for LAN emulation. port_name Specifies the OSA port name. The name must be unique within one logical partition and it must be unique for an OSA port shared by multiple logical partitions. The maximum length for port_name is 8 characters. For an IBM Open Systems Adapter (OSA) port customized for HPDT ATM native mode, port_name must match the portname specified at OSA customization through OSA/SF. If used by TCP/IP, this name must also be defined as the portname in the TCP/IP Profile DEVICE statement. If used for SNA HPR over native ATM connection, this name must also be defined as the portname in the PORT statement in a VTAM XCA major node. For an IBM Open Systems Adapter-Express (OSA-Express) port operating in QDIO mode, the name specified for the port_name value is downloaded into the OSA at the time the first TCP/IP device for this OSA port is activated. For OSA-Express QDIO connections, this name must also be defined as the device name in the TCP/IP profile DEVICE statement for any TCP/IP stack that will use this OSA-Express feature. This name must also be defined as the port name on a VARY TCPIP,,OSAENTA command or the port name on an OSAENTA profile statement when a TCP/IP stack will start an OSA-Express network traffic analyzer trace on this OSA. /quote For OSA-Express QDIO connections, this name must also be defined as the device name in the TCP/IP profile DEVICE statement for any TCP/IP stack that will use this OSA-Express feature. corresponds to the post I made in the IBMTCP-L list, namely that the DEVICE statement name must be the same as the name specified by the PORT operand of the TRLE statement. There is also the following: quote name ... On TRLE: Assigns a required name for the TRLE. This name cannot match the VTAMLST member name containing this Transport resource list major node. For an IBM Open Systems Adapter (OSA) port customized for HPDT ATM native mode, the name must match the OSA name specified at OSA customization through OSA/SF. If used by TCP/IP, the OSA name must also be specified as the device name in the TCP/IP profile DEVICE statement. For an IBM Open Systems Adapter-Express (OSA-Express) port operating in QDIO mode the name specified here will be downloaded into the OSA-Express as OSA name at the time the TCP/IP device for this OSA connection is activated. /quote Are you using an Open Systems Adapter (OSA) port customized for HPDT ATM native mode?

FSVO 3rd; OS/360 had it's own spooling support, making JES1 the 4th. I understand that RCI was not copied to MVS. Alas! OS/VS2 was derived from OS/360 MVT. When Poughkeepise put the first release of VS2 out, they chose not to copy JES. They chose to use HASP and ASP doing the same thing they did in OS/360. They chose to use the native spooling of OS/360; the ASP and HASP upgrades were done by different groups. I think the first releases of VS2 were 1.0, 1.6, 1.7 and 1.8. The release after that was a major enhancement (2.0) and deserved a new name, OS/VS2 MVS, Multiple Virtual Storage, and the previous releases were retroactively renamed to OS/VS2 SVS, Single Virtual Storage. The name SVS was already used in OS/VS2 1.0, and several releases of MVS came out while SVS development was active. JES2 and JES3 each became a subsystem and SAM SI (emulating QSAM or BSAM) called the subsystem. No. The CI did normal VSAM macros against an ACB.

Re: IPCS L command returns KEY(??)
Al,
The KEY() piece of data in a storage display indicates the storage key
the block is in, whether it is protected or not, has it been referenced
and has it been changed.
The last time I looked this up, and I don't remember where I found it,
the KEY() value decodes to the following:
KEY() = ?? means that the storage protection information is not
available
KEY() = FF see KEY() = ??
Otherwise:
KEY() = B'prc?':
= storage key of the 4k block
p = 0 = page is not protected, 1 = page is protected
r = 0 = page has not been referenced, 1 = page has been
referenced
c = 0 = page has not been changed, 1 = page has been
changed
If memory serves me correctly, the referenced and changed bits are the
status since the page has last been paged out. However, someone will
probably correct me on this if I am wrong.

Re: Questions on ATTACHX's ETXR exit routine
(Old thread, just got back) The savearea provided to the ETXR is 72 bytes long. A CAUTION. In many cases it is not safe (system intergrity wise) to use the savearea pointed to by R13 if you are running in a space that could have user tasks (not yours) running. For example, consider a vanilla key 8 address space, where you have at some point switched to key 0 and done an ATTACH with ETXR for the attached routine to get control in key 0. In this case, the R13 savearea is in key 8. I did some testing and more reading and discovered the following... a) The Extended Addressability Guide says that each workunit (TCB or SRB) has its own stack. From that I it appears that the IRB is sharing the stack with the orginating task. So, I won't be using the stack to save the state in the exit. Hence the second question on the size of the save area provided by the system for the exit. As Binyamin asked, Why can't you use the stack? You are using the same stack, but you would not be overwriting existing entries if you use it, you would be creating new ones. As a result of the CAUTION case that I mentioned above, we almost always use the linkage stack for ETXR reg saving. b) I checked the contents of 4(r13) and 0(r14) upon entry to the ETXR. 4 (r13) does not contain F6SA, so I assume it's a standard 72 byte save area; and r14 does point to an SVC 3. This is not a good assumption, though the conclusion is true. The presence of information such as F6SA at offset 4 says little about the length or format of *this* area. It is primarily a statement about how registers were saved (or not saved) in the previous area. Since there is no previous area, no data is provided. If you were to provide your own, chained, savearea, you would put into it how you saved the registers in the system-provided area (such as by putting the 'previous pointer' or F1SA if you used the linkage stack).

If you are running on z/OS 1.7 or higher, and this is an SVC dump, then this is probably storage that was either in a first reference state (i.e. unbacked, and would be backed by a page of zeros when eventually referenced), or backed but unchanged with no copy on AUX (so we know the data is all zeros). In these cases, SDUMP avoids dumping the page (to save time and space), but creates some summary information which allows IPCS to tell you that the data is all zeros. Prior to z/OS 1.7, IPCS would have told you that the storage is unavailable. SDUMP does not know the key of the page (or the key that the page would have when it eventaully gets backed) in these cases - the RSM interface used by SDUMP does not provide that information), so SDUMP cannot supply the key to IPCS.

Re: Industry Standard Time To Analyze A Line Of Code
Back in the 80s, we operated under the premise that a seasoned programmer should be able to produce 20 lines of bug-free assembler code per day. However, it is vital to note that this is addressing code development, not code revision. The problem in development this type of performance metric is that you must have different metrics for code development vs. code revision and a separate set of metrics for each programming language. In addition, the performance metrics used for application code are vastly different from the performance metrics used for systems code. There is an entire field of study regarding performance metrics when developing and revising code. It is one of the most different tasks that management has to address.

Miklos,
You have a couple of options,
A) Apply toleration PTFs to the zOS 1.4 system
or maybe try the following...
B)
1) use HCD option 2.10 to extract an MVSCP deck for the OSCONFIG you need
2) use IDCAMs to define a new IODF for 1.4 system
define cluster (na('sys1.iodfxx.cluster') linear tracks( 0)
volumes(x)) data(na(sys1.iodfxx))
3) use batch HCD using 1.4 modules STEPLIBed to format and import the
MVSCP deck
something like (I have typed this from memory.. so you might need to
check with the HCD Users Guide in the section on Batch JCL..!!)
//S1 EXEC PGM=CBDMGHCP,PARM='INITIODF,SIZE='
//STEPLIB DD DSN=
//HCDIODFT DD DSN=SYS1.IODFxx,DISP=OLD
//HCDPRINT dd SYSOUT=*
//HCDLOG DD SYSOUT=*
//*
//S2 EXEC PGM=CBDMGHCP,PARM='MIGR,OP,configname,MVS'
//STEPLIB DD DSN=
//HCDIODFT DD DSN=SYS1.IODFxx,DISP=OLD
//HCDPRINT dd SYSOUT=*
//HCDLOG DD SYSOUT=*
//HCDINDD DSN=your mvscp deck
The only minor issue is that the HCD modules are in SYS1.LINKLIB, and
you might have problems if you use the whole of the 1.4 linklib in your
steplib on your 1.7 system!! So just create a new library and copy all
the CBDM* modules from 1.4 linklib, and use this.. I doubt it will need
to be APF auth.. but you'll soon know ;-)
Dont worry about defining processors, chpids, Control units etc.. you
only need the OSConfig details and devices to IPL, and these all come
from the MVSCP deck that you created..

If I give a programmer an existing program to modify, how long on average will it take, per line of code, to analyze the program to then be able to then make necessary changes. It depends on how well documented the existing program is, how complex and well-defined are the necessary changes, and how much the specifications for the changes evolve before the project is finished. I've never heard this metric. Many decades ago I heard ca. 20 lines of new, debugged Assembler code per day per programmer. Someone else posted 17, which is ca. 20. I once had to add a functional comment to each executable instruction in a set of a set of about 20 Assembler modules for which there was zero documentation and zero comments. All I knew was that the programs worked correctly and I had a general idea of what they all did as a system. It wasn't very hard at all, since each module was only 40 to 50 instructions. I don't remember how long it took me, unfortunately. Bill Fairchild Plainfield, IL The chief use to which we put our love of the truth is in persuading ourselves that the thing we love is true.

Re: IODF convert backwards
I recently had to do apply the compatability PTF that Mark mentioned to a z/OS R4 one-pack rescue system. The APAR: OA08197 NEW FUNCTION ( SUPPORT IODF V5 DATASET ). The z/OS R4 PTF is: UA17026 ( there are PTFs for z/OS R5 R6 ). However, all 3 PTFs were PE'ed by APAR: OA15115. The goods news is the PE problem doesn't look too bad: Users Affected: Installations with APAR OA08197 (ptfs UA17026, UA17027, UA17028) installed and which use an older (pre-version 5) IODF. The problem will not be seen when a version 5 IODF is used. So if you already have a V5 IODF the PE APAR shouldn't be an issue.

B-A-D
There are obviously (too) many places where what turned out to be incorrect design decisions (or lack of design decisions) have led to the system not working the way it should. This is popularly referred to as broken-as-designed (BAD). It is true that typically design defects are not subject to field APARs. But despite some posts to the contrary, that doesn't mean that they must stay defects. Depending on the customer impact, they might be fixed by what used to be called an SPE (which basically is nothing more than an APAR opened internally) or in a followon release. However dumb a behavior might be, there is usually a pretty good chance that changing that behavior will break someone. We thus tend to make such changes in the next release where feasible (and highlight the change in the migration information) and/or make the customer who is applying service to an existing release specify some option to ask for the behavior change (i.e., not make a change in behavior by default in the service stream). Do we always get this right? No. But we hope we're doing better. Please don't give up on bringing these situations to our attention.

Re: Industry Standard Time To Analyze A Line Of Code
--snip More specifically, I'm looking at this from a maintenance perspective. If I give a programmer an existing program to modify, how long on average will it take, per line of code, to analyze the program to then be able to then make necessary changes. -unsnip--- That's rather like asking how many layers of Kleenex are needed to stop an artillery shell. The answer to your questions is very heavily dependant on such factors as the experience of the analyst, the complexity of the code, how many times will he/she be interrupted, etc. IMHO, entirely a matter of local judgement and not a good question for this group. -- 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: JES2 check point in CF and DR
We've been XRC mirroring DASD between data centers about 100 KM apart since the late 90s. When we started, we were using much slower technology than we have today. DWDM over 'dark fiber' in conjunction with modern RAID DASD have changed the metrics of what can or cannot/should not be mirrored. In the beginning, we did not mirror the JES spool at all because we deemed the cost too high. (We've never used CF for checkpoint.) We defined 'place holder' volumes that allowed for a cold start during DR using a copy of the production init deck. The view was that we could always rerun any jobs whose output had not already been pulled off spool by sysout archival software. The greater concern over time was that without a current snapshot of the JES queues, we could not easily figure out exactly where we had left off at the moment of mirror breakage. In a twenty step job, where did we die and what needed to be rerun? How would we even know which jobs were running at the time? Rather than solving that specific problem, we eventually tried mirroring the entire spool. By this time conventional channel extension had been replaced by DWDM. The DASD was hugely faster at both ends. When we actually turned on spool mirroring for the first time, we could hardly measure a blip in XRC traffic. We were astounded at how simple the complete solution turned out to be. So, if your XRC transport technology supports it, I highly recommend mirroring your entire spool. 1. Leave your primary checkpoint in the CF if you find benefit in that configuration. 2. Mirror your secondary checkpoint and all spool volumes. 3. In DR, IPL with the mirrored checkpoint as primary. 4. As soon as practical, reconfigure JES to get your primary checkpoint back in a local CF. It's important to remember that the primary/secondary checkpoint architecture evolved over decades to allow recovery from loss of the primary. Remember when DASD volumes used to drop like flies in a smokehouse? It wasn't that long ago. Much of what gets written to the primary checkpoint provides for serialization of JES resources in a MAS. In DR, the secondary checkpoint is a pretty reliable starting point for mapping the existing spool data. That's what it was designed to do, and refinements over many years have made it work extremely well. Chances are that your JES in DR will come up cleanly with minimal complaints. What can't be mapped exactly will be repaired or if necessary purged in order to yield a fully functioning system. You will lose very little data in recovery. A fully mirrored spool has solved all sorts of problems for our DR. Give it a try! . .

We currently have our primary check point in the CF and second one on DASD. We know they aren't in SYNC maybe a few writes behind on DASD. We mirror using IBM XRC to another site for DR purposes. We are thinking of taking both check pints and moving it to DASD so both check points are mirrored. I guess the basic question we are asking ourselves is it worth putting the check point back

Mike. I am right assuming the solution you described , does not cover tapes created after the switch to RMM in protect mode , after several VRSEL runs ?.

New File system From IBM
http://www.theregister.co.uk/2007/10/02/ibm_gpfs_3point2/ IBM upgrades brain-bending file system GPFS - it's about policy By Austin Modine in Mountain View → More by this author Published Tuesday 2nd October 2007 22:49 GMT IBM on Friday is releasing a new version of its General Parallel File System (GPFS) for serious data crunchers. The update, now version 3.2, features improvements to GPFS's policy- based file management system and offers speedier searches. GPFS caters to hardcore users trying to run a file system across numerous systems. It provides shared access to the files regardless of what box in particular they are sitting on. IBM says GPFS can support access speeds of 130+GB/sec to a single file on a 2PB file system. The update includes a revamped version of the existing, built-in policy manager that should make tweaking rules for storing and shifting data easier on customers. This type of technology comes in handy when tiering data across systems that have billions of files to manage, said Todd Neville, IBM development offering manager. The file system can, for instance, let users specify that a certain type of file will be stored on higher performing disks. Users could also move all specific file types to lower-end systems if they have not been accessed for a certain amount of time, said Neville. IBM said a pre-release version of the fresh GPFS was able to scan one billion files in less than three hours in an internal benchmark. They say with further improvement of the policy performance through parallelization techniques, they'll whittle the number down even further. Other improvements include an accelerated file identification process for managing tiered storage, and support for pools of storage on tape. IBM has also added clustered management features. Version 3.2 supports IBM System p systems, including the Power6-based IBM System p 570 server and machines based on Intel or AMD processors such as the IBM System x boxes. Supported operating systems include AIX Version 5.3 and some versions of Red Hat and SuSE Linux. IBM's GPFS competes against homegrown software from the likes of SGI and Sun Microsystems along with open source and start-up offerings. ® -- 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
