Re: Detect the loop for batch job

Considering the speed of today's processors, all batch programs that run for more than a few seconds must of necessity contain one or more logic loops; so I assume the intended question is how do you determine if the program is in a non-productive loop. In general making this determination automatically by any tool without knowing something about the expected or historic behaviour of the program is an impossible task. And in the practical world it's not just applications that will never terminate that are a problem, but also those which cost more in resources than the end user can afford. You want to catch a batch job step that is badly designed or poorly tuned that consumes an order of magnitude more CPU than required, as this is also a problem even if it may not be in an infinite loop. If the general issue is one of jobs wasting resources (which with sub-capacity licensing may cost real money), then the simplest first step is to impose and enforce standards requiring reasonable CPU TIME limits on jobs and job steps in JCL, and possibly also require OUTLIM to restrict SYSOUT loops in testing (needless to say NOLIMIT for CPU time should not be allowed for any batch job). Different default limits can be set for testing vs production via JES2 definitions based on job classes, and it is possible to use an IEFUTL exit to provide for unanticipated application growth by allowing Operators the option of granting CPU time extensions or cancelling production jobs that reach the limit based on job class. JCL overrides for higher limits could be allowed for specific job steps that have known higher requirements where the cost is acceptable to the end user. Rate of CPU consumption by itself is an unreliable indicator of problems. A single-threaded program would be limited to 100% of one CP, but even a solid, infinite CPU loop could show up as a much lower value on a loaded system, and some very efficiently-designed, computationally-intense programs might be able to approach 100% of a CP on a lightly loaded system and still be doing productive work. Some very simple tools, like SDSF DA display, that show both CPU and EXCP resources used, are sometime sufficient to provide clues. If the program is known to require periodic I/O to do anything useful and it is consuming an unusually amount of CPU time with no EXCPs, that would be strongly suggestive of a problem; or if the program is generating much more SYSOUT than usual or repetitive SYSOUT lines, again a likely problem. If the program is using both CPU and EXCPs, but a lot more than expected and no other obvious perverse behaviour, it is more difficult to make a determination. Other tools, like Omegamon, that show EXCPs on specific DDs in the job step may allow one to see if the program is continuing to progress through sequential data and if the total number of blocks is known may allow you to estimate if it will complete in an acceptable time and at what total cost. Or EXCPs on a file way in excess of the total number of blocks in the file may point to a poorly tuned or poorly designed application. In our experience, there is no substitute for having human intelligence in the monitoring loop when resources get tight. -- Joel C. Ewing, Fort Smith, AR I agree.

Re: Missing RACF exit
Paul, As far as I am aware, if the exit pointer in the RCVT is non-zero then RACF will invoke the exit. About 15 years ago I knocked up a quick+dirty program to dynamically add a RACF exit and it seemed to work OK. I have not seen RACFXITS - however the logic I used was something along the lines of : (o) Determine length of RACF exit (o) Grab that amount of E-CSA and assign ownership to the system (ie I want it to persist) (o) Directed load of the exit module into the E-CSA chunk (o) Store the E-CSA address into the RCVT (remembering to indicate AMODE in bit0) These days you have things like dynamic LPA - so you might be able to avoid most of the heavy lifting and just zap in the new exit address.

I regard such code as inelegant, yet convenient, short-cuts that work most of the time. Kludge. I fear we're losing the forest for the trees. Here's the problem. Say I'm in a large production shop. We have production JCL that runs to hundreds of thousands or perhaps millions of lines spread across myriad batch jobs. Jobs often stall due to recalls before data sets are deleted; once in a while I blow a batch window because of this. I know how to change the jobs to eliminate the problem, and I do it when I must. But every change to every production job is moderately labor-intensive: - A change control record must be opened, and the change justified and approved. - The change has to be made, tested, and documented. - The documentation has to be reviewed and accepted by production control. - The job has to be changed in the production control system. The probability of error rises with the complexity of the change. While I think prior posts have shown how I think about the use of IEFBR14 as a data set allocation and deletion 'utility', the fact is that many hundreds or perhaps thousands of jobs that use it that way might exist in a large installation. For each of them, the process above--designed, to be fair, to assure production batch quality--must be followed. If I wanted to change them all, programmer and administrator months (or years!) would be consumed. In an ideal world with infinite resource, I'd bravely bear the cost and defenestrate every single use of IEFBR14 for this purpose, replacing it with a real utility (and appropriate control statements) that will, among other things, provide a return code to indicate success or failure and isolate failures to the actual failing step to simplify diagnosis and restart. In the real world, this ain't gonna happen. Large-scale production JCL changes are an anathema. I want a magic wand to make the problem go away (and I want it *NOW*).

Re: CF LPAR MIPS Utilisation
I also don't see which LPAR's are part of the Sysplex, and which are not. Dynamic Dispatch with a CF LPAR is not so much a matter of utilization, but as Scott suggests, getting the CPU when the CF needs it. We have found that DynDisp dramatically increases ISGLOCK response times (at least one order of magnitude) - and we have characterized CF engines. I cannot imagine how much worse this would be if we had to share with MVS images, too. IMHO, if A and B are the only ones in the Sysplex, the parallel sysplex does not give you significant advantage in and of itself in this configuration, unless of course, you have it for pricing considerations. Yes, GRS Star (parallel sysplex required) does perform better than Ring, even in a two-system complex, but without dedicated CF engines, my gut tells me you are losing whatever ground Star gives you. If A, B, C and D are all in it together, then IMHO, seriously consider funding and characterizing an ICF CP. Also, if they are, and since you are on a single footprint, I do not see the advantage of two CF LPARs for a single complex. If an internal CF goes down, it's either because your Operators need to be more astute, or there is a serious hardware problem, which probably means the whole machine is down. When our European counterparts tried to implement Star a few years back, they found this out empirically, also notwithstanding the added CPU demand buried their already-taxed z990.

According to your calculations, your CF partitions are promised 100 and 36 MIPS respectively - but is that enough?

RES: Missing RACF exit
You can try another approach by specifying CSVDYNEX interface to call a dynamic ICHRIX01 exit. Of course you will need an IPL, but after that the dynamic exit could be activated/deactivated/changed in flight. You have to create a static ICHRIX01 exit, loaded at IPL time, which can have a logic like this : Query DYN.ICHRIX01 IF NOT Defined OR Only Defined IMPLICIT Then DO Define DYN.ICHRIX01 END CALL DYN.ICHRIX01 IF Exit Module is ACTIVE Then DO EXIT MODULE executes and Returns END Additionally you have to define it in SYS1.PARMLIB : EXIT ADD EXITNAME(DYN.ICHRIX01) MODNAME(DYNRIX01) The DYNRIX01 will have the logic that normally would be coded in ICHRIX01, and can be located in linklist.

Re: CF LPAR MIPS Utilisation
Art, In my experience, GRS-Star with shared CP CFs is still significantly faster (at least one order of magnitude) than GRS Ring using XCF. Also, the purpose for the extra CF can be used to upgrade CF code without a Sysplex outage. I guess it's also remotely possible that a CF code fault could cause a CF failure, though I have yet to see this. I keep a second CF running for this purpose, though I don't currently have any active structures in it. Scott Arthur Gutowski aguto...@ford.com 12/7/2009 9:25 AM I also don't see which LPAR's are part of the Sysplex, and which are not. Dynamic Dispatch with a CF LPAR is not so much a matter of utilization, but as Scott suggests, getting the CPU when the CF needs it. We have found that DynDisp dramatically increases ISGLOCK response times (at least one order of magnitude) - and we have characterized CF engines. I cannot imagine how much worse this would be if we had to share with MVS images, too. IMHO, if A and B are the only ones in the Sysplex, the parallel sysplex does not give you significant advantage in and of itself in this configuration, unless of course, you have it for pricing considerations. Yes, GRS Star (parallel sysplex required) does perform better than Ring, even in a two-system complex, but without dedicated CF engines, my gut tells me you are losing whatever ground Star gives you. If A, B, C and D are all in it together, then IMHO, seriously consider funding and characterizing an ICF CP. Also, if they are, and since you are on a single footprint, I do not see the advantage of two CF LPARs for a single complex. If an internal CF goes down, it's either because your Operators need to be more astute, or there is a serious hardware problem, which probably means the whole machine is down. When our European counterparts tried to implement Star a few years back, they found this out empirically, also notwithstanding the added CPU demand buried their already-taxed z990. FWIW, Art Gutowski Ford Motor Company On Fri, 4 Dec 2009 14:33:18 -0500, Scott Rowe scott.r...@joann.com wrote: Certainly, SYSA can take unused cycles, they are distributed according to weights. What you haven't said is what mode your CFs are running in, so I will assume the are dynamically dispatched. The thing you need to be very careful about here is that the CF partitions can get the cycles they need when they need them. According to your calculations, your CF partitions are promised 100 and 36 MIPS respectively - but is that enough? I prefer to over- weight CFs that run on shared CPs, since it helps ensure that the CF has access to the CPU when it needs it. If there are many CF requests and not enough available cycles to service them you could get in trouble quickly. John Mitchelle john.mitche...@googlemail.com 12/4/2009 11:57 AM Hi, I have 936 MIPS processor Z02-2096 z9BC I have 4 LPARS and 2 CF LPARs SYSA (Prod) SYSB (Dev) SYSC (Test) SYSD (Maint) SYCF1 SYCF2 Both CPU Engines are online across all LPAR's.

I did this under z/OS V1R9. Since we did things to prevent it, I would have to break the code to recreate under z/OS V1R10/11. During design, we concluded that we had to use the ISPF EDIT ENQUEUE. But during testing we found that if you are doing a STOW for member X while another task is attempting member Y at the same time, the ISPF EDIT ENQUEUE does not protect the directory from a simultaneous update situation, only from two tasks using the same member. In order to prevent this ABEND situation, we decided to use an ENQUEUE for the directory updates. The ENQUEUE actually protects from the problem within one address space or across two -- and only between uses of the product (which is still underdevelopment) since the ENQUEUE we came up with is private. The STOW situation I ran into did not require a member write, only that you wish to update the directory entry. In my case, attempting to add the ISPF stats caused the ABEND. And because of race (or timing as you prefer) conditions I was getting two STOWs being done at the same time to the same directory. The system detected this and the arbitrary second updater got the ABEND.

I did this under z/OS V1R9. Since we did things to prevent it, I would have to break the code to recreate under z/OS V1R10/11. During design, we concluded that we had to use the ISPF EDIT ENQUEUE. But during testing we found that if you are doing a STOW for member X while another task is attempting member Y at the same time, the ISPF EDIT ENQUEUE does not protect the directory from a simultaneous update situation, only from two tasks using the same member. In order to prevent this ABEND situation, we decided to use an ENQUEUE for the directory updates. The ENQUEUE actually protects from the problem within one address space or across two -- and only between uses of the product (which is still underdevelopment) since the ENQUEUE we came up with is private. The STOW situation I ran into did not require a member write, only that you wish to update the directory entry. In my case, attempting to add the ISPF stats caused the ABEND. And because of race (or timing as you prefer) conditions I was getting two STOWs being done at the same time to the same directory. The system detected this and the arbitrary second updater got the ABEND.

Re: Detect the loop for batch job
Well we in OMEGAMON have been working on the cpu looping issue lately: Detecting an address space in an infinite loop is not an easy job. Our modern z/OS LPARs often have multiple CPUs and specialty processors like zIIP and zAAP where instructions can be dispatched. In addition Workload Manager will try to distribute processor resources equitably based on the current workload mix and priorities defined in the installation?s policy. Lower priority batch workloads that happen to be looping can easily run under the radar for long periods of time squandering resources. OMEGAMON XE on z/OS 4.2.0 with the addition of Interim feature 1 has a strategy to help surface these problems. OMEGAMON has had a feature called Bottleneck Analysis for many years. Bottleneck Analysis builds a profile over time through periodic sampling of what execution states are being used by address spaces. These execution states include things like Using CPU, Using zIIP, Using zAAP, Waiting for CPU, Waiting for zIIP, Waiting for zAAP, Using I/O, Waiting for I/O, Waiting for Enqueue, Waiting for HSM, Swapped, etc. A cpu looping address space will reveal itself by populating only the using and waiting states for CPU resources (including zIIP and zAAP). OMEGAMON XE on z/OS 4.2.0 has a new attribute called CPU Loop Index that uses this bottleneck information as its basis. High priority workloads can be reliably detected fairly quickly. The real trick is discriminating between well behaved low priority work that is just starved for attention from low priority work that is looping. OMEGAMON XE on z/OS 4.2.0 Interim Feature 1 provides this discrimination by dynamically extending the observation period required before indicating a likely loop when the ratio of waiting for CPU to Using CPU is high. For more information on OMEGAMON XE on z/OS approach to CPU Loop detection please see the article titled ?Detecting CPU looping address spaces using IBM Tivoli OMEGAMON XE on z/OS version 4.2.0? in the August issue of the z System Advisor at http://www-01.ibm.com/software/tivoli/systemz-advisor/2009-08/.

Re: Safe C++ char array functions (Was Is there a good mailing list or forum for mainframe C/C++ specifically?)
Strlcpy is certainly an equal opportunity solution -- it's not available on
EITHER of the platforms I am working with.
My impression is that strcpy_s does *not* copy anything if the target buffer
is too short.
Hey, anybody want my implementations of a safe strcpy and sprintf? Here you
go:
// sprintf_ss is a local one-for-one replacement for Microsoft sprintf_s
// replace all references to sprintf_ss when/if IBM implements on z/OS
int sprintf_ss(char *string, size_t sizeInBytes, const char *format, ...)
{
va_list args;
assert(format != NULL);
//assert(string != NULL); // not necessary; hardware
will detect
va_start(args, format);
int ret = vsprintf(string, format, args);
va_end(args);
assert(strlen(string) sizeInBytes); // note that the damage is
already done!
return ret;
}
// strcpy_ss is a local one-for-one replacement for Microsoft strcpy_ss
// replace all references to strcpy_ss when/if IBM implements on z/OS
// note not quite one-to-one as uses assert() rather than error returns
errno_t strcpy_ss(char *strDestination, size_t numberOfElements, const char
*strSource)
{
assert(strlen(strSource) numberOfElements);
//assert(strDestination != NULL); // not necessary;
hardware will catch
assert(strSource != NULL);
strcpy(strDestination, strSource);
return 0;

Correct on strcpy_s versus strncpy. Strncpy has the possibility of making
a
new bad situation while preventing another. You can easily end up with a
string that is guaranteed to run wild if you strcpy it.
I personally have always preferred strlcpy to strncpy or strcpy_s, since
strlcpy is basically an always-safe copy function that doesn't have the
defects of strcpy_s (does nothing if the dest is too small, instead of
copying as much as it safely can) or strncpy (doesn't always null-terminate
the result; and always touches every byte of the dest area, which can be a
massive time-waster for large dest buffers).
The only problem with strlcpy is that it's not supported on many platforms,
any more than strcpy_s is...

Clues on using C++ prelink * lked for first time
I've got my first mainframe C++ application. It runs under Windows. (Obviously, that's not the same as running under z/OS, but the point is it's a complete program. My concern at this point is getting it to link, not run.) It compiles cleanly under z/OS C++. I have long names and want the load module in a PDS, so I'm running the compile/pre-link/link proc. There are eight object modules from eight source files in an HFS path. I'm good up to that point. Questions: 1. How do I specify the input to the prelinker? I tried LIBRARY with a DD name pointing to my object path and all of the object files listed in parentheses. If I do that, the prelinker runs to completion with a zero return code and nothing in SYSPRINT, but the link fails on a SYSLIN that is apparently empty (wrong length record, that sort of thing). SYSLIN is the same dataset as the prelink SYSMOD. How do I know if the prelinker actually did anything? My guess is that it did not. (SYSMOD specfies FB/80/3200 and SYSLIN lets it default.) 2. If I specify INCLUDE with a DD pointing to the main() object module and LIBRARY with a DD for everything else, I get a warning of unresolved extrns, but it still runs to a zero completion, and I still get the same error out of the link editor. Any clues? Is the prelinker documented anywhere other than the C++ User's Guide?

Re: Clues on using C++ prelink * lked for first time
Charles Mills wrote: I've got my first mainframe C++ application. It runs under Windows. (Obviously, that's not the same as running under z/OS, but the point is it's a complete program. My concern at this point is getting it to link, not run.) It compiles cleanly under z/OS C++. I have long names and want the load module in a PDS, so I'm running the compile/pre-link/link proc. There are eight object modules from eight source files in an HFS path. I'm good up to that point. Questions: 1. How do I specify the input to the prelinker? I tried LIBRARY with a DD name pointing to my object path and all of the object files listed in parentheses. If I do that, the prelinker runs to completion with a zero return code and nothing in SYSPRINT, but the link fails on a SYSLIN that is apparently empty (wrong length record, that sort of thing). SYSLIN is the same dataset as the prelink SYSMOD. How do I know if the prelinker actually did anything? My guess is that it did not. (SYSMOD specfies FB/80/3200 and SYSLIN lets it default.) 2. If I specify INCLUDE with a DD pointing to the main() object module and LIBRARY with a DD for everything else, I get a warning of unresolved extrns, but it still runs to a zero completion, and I still get the same error out of the link editor. Any clues? Is the prelinker documented anywhere other than the C++ User's Guide? Thanks, Charles Mills It is probably easiest to do this from a Unix Service shell using the c++ command. See the description of the c89 command in Unix System Services Command Reference, and in particular the prefix_STEPS environment variable. It has been a long time, but I believe if the target of the link is a PDS, the prelinker is invoked automatically even without the prefix_STEPS environment variable. Regards.

Re: Portable data centers (was RE: Small Server Mob Advantage)
No kidding! Was Sun even born yet? I started with my current employer in 1984. Couple of months later, we were putting in a new mainframe. A full sized 18 wheeler (probably a 65 footer) pulled up along side the building, along with another one with generators to run the mainframe in the first. Our data center was pretty small and in order to swap out the mainframe the workload was moved on to the machine in the truck while we did a push/pull in the data center. We ran the better part of a week like that, then we cut over to the new machine in the data c enter. Changed out the mainframe with only 2 IPLs worth of outage. Pretty fine. Not SUN , IBM.

Hey Neil, We did get the dataset list from FDRABRP and we are working with that. I would have liked to restore all dsn except VSAM, but we are finally making some progress .

Re: A WebSphere Virtual Enterprise (z/OS) consultant
Marc, Just to clarify (and as a public service): the skills required for WebSphere VE for z/OS are a relatively small increment over WebSphere Application Server for z/OS, generally speaking. (The VE features simply build on the WAS foundation.) Would you (and your client) also be interested in responses from consultants who know WAS for z/OS? If so, that would increase the number of people who could respond favorably yet still likely meet or exceed your client's requirements. Alternatively, if your client is focused on the unique/additional VE functionalities, then experience with those functionalities on any WAS platform should be sufficient if your client already has what they need for WAS z/OS skills. So you could cast a wider net in that direction. Finally, you may also want to add ...or the Operations Optimization features in WebSphere Extended Deployment (WebSphere XD). WebSphere Virtual Enterprise was known as Operations Optimization until it got a proper (or at least different) name, so anyone with Operations Optimization background should also be eligible. Hope that helps. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Based in Tokyo, Serving IBM Japan / Asia-Pacific E-Mail: timothy.sipp...@us.ibm.com -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: Detect the loop for batch job
Hi Joe, Interesting development in Omegamon. I am still new to Omegamon, but I am going to install V4.2 next month, how do I check if I have Interim Feature 1, how do I install it? Kees. Joseph H Winterton jose...@us.ibm.com wrote in message news:of614ad680.d9513ffb-on86257685.0060f861-85257685.00614...@us.ibm.c om... Well we in OMEGAMON have been working on the cpu looping issue lately: Detecting an address space in an infinite loop is not an easy job. Our modern z/OS LPARs often have multiple CPUs and specialty processors like zIIP and zAAP where instructions can be dispatched. In addition Workload Manager will try to distribute processor resources equitably based on the current workload mix and priorities defined in the installation?s policy. Lower priority batch workloads that happen to be looping can easily run under the radar for long periods of time squandering resources. OMEGAMON XE on z/OS 4.2.0 with the addition of Interim feature 1 has a strategy to help surface these problems. OMEGAMON has had a feature called Bottleneck Analysis for many years. Bottleneck Analysis builds a profile over time through periodic sampling of what execution states are being used by address spaces. These execution states include things like Using CPU, Using zIIP, Using zAAP, Waiting for CPU, Waiting for zIIP, Waiting for zAAP, Using I/O, Waiting for I/O, Waiting for Enqueue, Waiting for HSM, Swapped, etc. A cpu looping address space will reveal itself by populating only the using and waiting states for CPU resources (including zIIP and zAAP). OMEGAMON XE on z/OS 4.2.0 has a new attribute called CPU Loop Index that uses this bottleneck information as its basis. High priority workloads can be reliably detected fairly quickly. The real trick is discriminating between well behaved low priority work that is just starved for attention from low priority work that is looping. OMEGAMON XE on z/OS 4.2.0 Interim Feature 1 provides this discrimination by dynamically extending the observation period required before indicating a likely loop when the ratio of waiting for CPU to Using CPU is high. For more information on OMEGAMON XE on z/OS approach to CPU Loop detection please see the article titled ?Detecting CPU looping address spaces using IBM Tivoli OMEGAMON XE on z/OS version 4.2.0? in the August issue of the z System Advisor at http://www-01.ibm.com/software/tivoli/systemz-advisor/2009-08/.
