MFNetDisk will be a free product soon.
HI, In a few days I will make MFNetDisk really a free product. That mean you will be able to work without the limitation of number of devices. Why I am doing this: 1. I do not think that there is a space for another IO devices in MF. 2. The price of MF IO devices is very low and the competition is hard. 3. I think all my challenges with the product is over. 4. It is time only to support the product and I can not see any new feature in my product which I can create which will exciting the MF users. 5. As i said before, it was pleasure to dig in the MF as it pleasant to dig in the Linux and Windows. This product was developed first because I enjoy it. Just to remind, 1. MFNetDisk support emulation of disk 3390 and tape 3490 with data in Windows and Linux. 2. Mirror real 3390 disks. 3. Support EAV disks for emulation. 4. Tape manager in PC and MF. 5. Undelete Vsam and SMS and Non SMS files. 6. MFNetDisk CIOD (like IBM Pav for the emulation). 7. Backups of MFNetDisk disk with backup level of one track. and many more features..

Re: SYSPLEX/CFRM Couple dataset(s) relationship
We have done quite a lot of DR testing in the last year and a half. We defined all coupling facilities in our active CFRM policy, the same way Alan C. Field described, and never had a problem IPLing our sysplex. The only difference is that we start JES2 with RECONFIG parameter, to set the CKPT1 (allocated in a coupling facility) to INUSE=NO, so that the CKPT2 will be used. Never had any problems going back either. With applications it is not so easy, but starting a sysplex is just a routine. The tests were done with z/OS 1.9 and 1.10. -- Zaromil -- 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

Then obviously you've never done Capacity Planning, Performance Management or Chargeback. Very far-fetched opinion, unjustified. To clarify: I don't see any relationship to SCRT. Without going into details, a standard methodology of allocating CPU usage for planning purposes is merging type 70, 72, and 30 (interval). Only one of those has hardware details. Simply put, 70 gives me the detail of overall usage, 72 allows for the breakdown by workload (with capture ratios applied), and 30 allows me to determine which application within workload. Type 110 allows for a merging of CICS transactions (for this example), along with other details. 74 gives me the I/O component. With other records (I've only given a few examples), I can end up with a profile vector, of CPU, LPAR, Workload, application, I/O, and other details.

Re: RMM and VRSMIN
David, Consider that the loss of just a single VRS could cause you to lose a lot of data. So, the problem is not about losing/deleting 1000s it is about avoiding loss of data. RMM provides multiple options to help with this: VRSMIN allows you to identify a value which you identify as the critical number of VRS. This might be ALL of your VRSes. Some one with just a small number may feel the count should match there number of VRSes. If you have 1000s, which I wouldnt recommend ;-), and you look to VRSCHANGE - you could perhaps do what Tom suggests. VRSCHANGE This is a way to enforce a 'trial run' of VRSEL should anyone add/change or delete VRSes. Using this option might make the VRSMIN count less important VRSRETAIN, VRSDROP, EXPDTDROP These more recent options provide a way to direct rmm to detect when result of retention are not what you would normally expect. RMM provides these options because of the cost of data loss, and the effort required to retrieve data that has been scratched prematurely. We have to think about deliberate actions, accidents, and code defects as the possible triggers. Mike WoodRMM Development On Mon, 12 Apr 2010 10:50:49 -0700, David G.

Ed, My perceived observation is that varying devices and paths in z/OS takes much longer and uses more resources than it did many moons ago under ESA, XA or SP2. It's my understanding that a lot of device validation that used to occur at IPL when a device was discovered now occurs when the device comes online, hence a faster IPL, but a slower vary online. For example varying just 256 volumes online on 2094-408 with one dedicated CP online locks up TSO for a minute or three, and usually drops my NJE links (yeah I'm too lazy to tune this - it's a lab). I don't recall this behavior way back on 3033 or 4341, or any uniprocessor LPARs I had in early PR/SM and MLPF.

It *NEVER* caused any issue with the system and we never saw any system abends as a result of these hundreds of vary commands being issues. Granted this was 25++ years ago but I would have thought if there would have been a bug we would have found it. IIRC the biggest issue we had was that Q4 was being so backed up we found (actually IBM) was surprised at the length of our Q4. What added into our mix (for the Q4) was we had a MSS which caused us all a lot of headaches.

No. There are many reasons where unique SMF ID would be advantage, but it's still not necessary. Even one is enough. Once you have a single valid reason, all else pales in comparison. Convenient, not required. I disagree. There are many 'required'. And, one is enough. Convenience is in the eye of the beholder. I've had many reasons for unique IDs, and SCRT just came along for the ride. But, obviously, we disagree. I've never worked in a shop where more than one system had the same SMFID. Nor would I want to. In this case, convenience is being able to do my job without doing strange and unusual acts. And, if you restrict yourself to just the upper case alphabet, you still have 26 to the 4th possibilities.

Re: Putting system integrity at risk to save software charges
This is a horse of a different color and there is more than one way to skin a cat (horse). Evidently, IBM has privately, you have to be an ISV, gratuitously shared with them the internals of the ziip/zaap engines and how to go about configuring products to take advantage of them. Data Direct claims to have done just that; to have taken what IBM has given them, done a nice dance, and somehow faked out the operating system into thinking they are running workloads in TCB mode when infact they are running the work on a ziip/zaap in SRB mode. They also claim to have done this without violating IBM patent rights which appears credible since IBM has sued at least one ISV about this, but not Data Direct. All I can surmise is that they have somehow figured out how to run perhaps a daemon on a ziip/zaap which gets control to perform tasks on behave of regular TCB workloads like CICS. Something like a client/server, master/slave, pair process. They are very adamant, reprimanding me here last month, in stating that they positively do not run TCB workloads as is on a ziip/zaap since that would be a clear violation of IBM's patent rights. Evidently, it's all done with smoke and mirrors, but the end result is the same, more MIPS, more throughput, for almost nothing. Nice life if you can get it and you can get it if you try.

The installation was transparent to their applications. All they did was install the product, reconfigure the ziip an the HMC panel, and they were off and running. If you are talking about high profile actuarial computations, check with the vendor, they are probably covered as well, since my former client is a leading insurance company in New Jersy. According to their Chief Architect http://blogs.datadirect.com/2009/07/setting-the-record-straight-datadirect-shadow-is-not-affiliated-with-neon-enterprise-software.html that isn't what they do.

Re: Putting system integrity at risk to save software charges
I met the designer of Data Direct at a conference and spoke to him about what they did and in general terms how they did it. Two things were very clear from that. They do not make or allow anyone's but their own code run on a ZIIP. Their secret is in how they made it so they could run parts of their code on a ZIIP without having to re-design and re-code the entire product. Parts of the code that do things not allowed on a ZIIP are run in TCB mode on a GP. What they did was very clever and innovative. The smart ISV's that are part of the sanctioned ZIIP program go to IBM and explain what they are doing and get IBM's blessings. It cuts down on the heartburn and legal fees.

What we did was get OpenTech's VDR product. This product copies our virtual tape data to real 3592J tape drives for off site storage. When we get to DR, we use the product to restore the data to a virtual volume. The product then updates the z/OS catalog as well as the CA-1 TMC so that we can access the tape data normally from the DR VTS environment. It also has an option to update the z/OS catalog and CA-1 TMC so that the data is accessed directly from the 3592J. We don't use this due to tape volume contention. We really like the product. More info at http://www.opentechsystems.com/vdr.php .

Re: omvs.root full due to pfa
Howard, I don't know PFA. However, what may be possible would be to create the PFA filesystem. Run the PFA install using that filesystem. Now, find the files in the root filesystem which match those in the PFA filesystem. Those are likely the ones you need to rm from the root. Something like the following set of UNIX commands may be of use: cd / #go to the root filesystem find . -type f -xdev | sort /tmp/root-files cd /PFA #go to the PFA filesystem find . -type f -xdev | sort /tmp/PFA-files thesame.rexx /tmp/root-files /tmp/PFA-files This lists the regular files in the root filesystem to /tmp/root-files and in the PFA filesystem to /tmp/PFA-files. The -xdev tells find not to recurse into subdirectories which are mounted onto by another filesystem (otherwise we'd get every file in house from the root). It pipes each of these into sort so that the file names will be in the same order. I then show the use of thesame.rexx. This would be a user written UNIX REXX program which finds and prints the lines which are in both files. There is no such in UNIX, so I'll include it below. This needs to be put in a directory in your PATH and marked executable (chmod 755 thesame.rexx) /* REXX */ parse arg in1 in2 rec1=linein(in1) rec2=linein(in2) do forever if lines(in1) = 0 then leave /* EOF on in1 */ if lines(in2) = 0 then leave /* EOF on in2 */ if rec1=rec2 then do say rec1 iterate if rec1 rec2 then rec2=linein(in2) else rec1=linein(in1) end You can then review this list of file to get an idea as to what you should rm from the root subdirectory. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.

Re: CA Vtape vs. IBM VTFM - Comparing virtual tape solutions
STK (and probably most) VTS solutions offer a dup function similar to dfHSM duplexing. The VTS does the work at the time of file creation, all you have to do is eject the back-end cart containing the dup copies. You can, if you think you can afford it, also have a remote VTS (at least with IBM) that will duplex each logical volume at dismount time, instead of each I/O. This does elongate mount times, though. The only cost is for the extra cartridges. In this case, the cost is for the duplicate library and network, as well. In your case, there is handling and transport to the DR site. P.S. Should you be letting your DR vendor drive your shop, or should your shop be driving the DR vendor to provide the necessary compatible equipment? Excellent question!

Re: Putting system integrity at risk to save software charges
That would be up to the details of how control is passed from TCB to SRB mode and back. Floating point registers are the afterthought of the system. On a task switch your FP regs are saved and restored when you get re-dispatched, but branching to a subroutine and back does not. As with many things, the devil is in the details, and to get into those details might be a little too much. I don't know if Direct Data's implementation saves and restores the FP regs across the TCB/SRB switch, I only know the concept. If it is important to them, then I am sure they coded for it.

From: Ron Hawkins ron.hawkins1...@sbcglobal.net To: IBM-MAIN@bama.ua.edu Sent: Tue, April 13, 2010 3:58:22 AM Subject: Ed, My perceived observation is that varying devices and paths in z/OS takes much longer and uses more resources than it did many moons ago under ESA, XA or SP2. It's my understanding that a lot of device validation that used to occur at IPL when a device was discovered now occurs when the device comes online, hence a faster IPL, but a slower vary online. For example varying just 256 volumes online on 2094-408 with one dedicated CP online locks up TSO for a minute or three, and usually drops my NJE links (yeah I'm too lazy to tune this - it's a lab). I don't recall this behavior way back on 3033 or 4341, or any uniprocessor LPARs I had in early PR/SM and MLPF. Ron Ron: That may well be true now days as the paths for many items has probably increased (although some have undoubtedly decreased). My memory is iffy but at least at one time I think Vary commands had to go through Q4. I vaguely remember having a discussion with a level 2 person and I think they recognized the issue. I can remember shooting a lot of Q4 issues (again this was 25+ years ago). I do remember sending more than a few standalone tapes off to IBM with Q4 problems. I think (if memory serves me) that Q4 was a major serialization problem area. I think IBM worked on minimizing the code path and or do some fast pathing through it. For a year we were probably IPLing once a week or more because of it. Somewhere along the lines IBM fixed it (or most of it anyway) and the problem almost disappeared. My memory is hazy as to the time period but I think it was before 3.7 (or there abouts). As to current issues I do not recall of hearing about lockouts due to (lots of) Vary commands. But there may be some uniqueness from installation to installation. Example: I have seen some installations allow tape mounts from a TSO session (I would never allow it) and that is where some delays might occur. Even with robotic libraries there could be issues with production getting drives that are needed. Of course if you have thousands of tape drives that situation shouldn't exist.

Millipede memory matches flash for durability * 11 April 2010 * Magazine issue 2755. Subscribe and get 4 free issues. A MILLIPEDE that can still remember where it was punched a decade later offers the prospect of increased digital storage. In 2002, IBM developed a punch-card system, known as Millipede, using a thin polymer sheet with nanoscopic holes to provide a simple way to store binary data. It can store hundreds of gigabytes of data per square centimetre. However, the polymer reverts to its pre-punched form over time, losing data in the process. Now researchers at IBM's Zurich Research Laboratory in Switzerland have clocked the rate of data loss. They have calculated that at 85 °C - a temperature often used to assess data retention - it would lose just 10 to 20 per cent of information over a decade, comparable to flash memory (Advanced Functional Materials, DOI: 10.1002/adfm.200902241). -- 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: LINUX on the MAINFRAME
Lot's of people are running Linux on the mainframe. It does not run under zOS, it can run in an LPAR or as a guest of z/VM. Installation is not much different from a PC, maintenance is identical, at least for SuSE. There are a number of Redbooks, check the IBM redbook site. I have no bad experiences. I highly suggest you join the Linux-390 listserv.

That is a very good point, John. Memory management on Linux for the mainframe is counter-intuitive.

Re: RMM and VRSMIN
Thanks, everyone, for the replies. We have 13,000 VRSs between two sysplexes. We're in the process of removing the unnecessary ones (90%?)and combining some.

Schlecht Subject: Re: RMM and VRSMIN David, Consider that the loss of just a single VRS could cause you to lose a lot of data. So, the problem is not about losing/deleting 1000s it is about avoiding loss of data. RMM provides multiple options to help with this: VRSMIN allows you to identify a value which you identify as the critical number of VRS. This might be ALL of your VRSes. Some one with just a small number may feel the count should match there number of VRSes. If you have 1000s, which I wouldnt recommend ;-), and you look to VRSCHANGE - you could perhaps do what Tom suggests. VRSCHANGE This is a way to enforce a 'trial run' of VRSEL should anyone add/change or delete VRSes. Using this option might make the VRSMIN count less important VRSRETAIN, VRSDROP, EXPDTDROP These more recent options provide a way to direct rmm to detect when result of retention are not what you would normally expect. RMM provides these options because of the cost of data loss, and the effort required to retrieve data that has been scratched prematurely. We have to think about deliberate actions, accidents, and code defects as the possible triggers. Mike WoodRMM Development On Mon, 12 Apr 2010 10:50:49 -0700, David G.

So, the problem is not about losing/deleting 1000s it is about avoiding loss of data. RMM provides multiple options to help with this: VRSMIN allows you to identify a value which you identify as the critical number of VRS. This might be ALL of your VRSes. Some one with just a small number may feel the count should match there number of VRSes. If you have 1000s, which I wouldnt recommend ;-), and you look to VRSCHANGE - you could perhaps do what Tom suggests. VRSCHANGE This is a way to enforce a 'trial run' of VRSEL should anyone add/change or delete VRSes. Using this option might make the VRSMIN count less important VRSRETAIN, VRSDROP, EXPDTDROP These more recent options provide a way to direct rmm to detect when result of retention are not what you would normally expect. RMM provides these options because of the cost of data loss, and the effort required to retrieve data that has been scratched prematurely.

IBM has not told me what the problem is, but I think I have a fairly good guess. Given what I have said earlier, I'm surprised that I'm saying this, but in this case the details of how to take advantage of this security hole is probably best left unstated.

Re: Non-SMS-managed LOGR offload data sets
On Apr 13, 12:57 am, nitz-...@gmx.net (Barbara Nitz) wrote: Nick, from your email I figured you're somewhere in LOGR development :-) And I am absolutely glad someone finally 'gets' my paranoia. I have a hard time getting the problem across to my colleagues, too! Mostly because they don't really understand how offload works. Barbara, Yes i'm in logger development. Also, keep in mind that I am not saying that we already *had* a corrupted RRS log stream, I just see a big timing window (that we will probably hit at the first opportunity - we always hit obscure timing problems) if we activate LOGR in both halves. Usually the system that does the offload for a log stream is the system that does the write causing the HIGHOFFLOAD threshold to be exceeded. So if your utility program ran on your TEST side, but didn't write to the log stream, the risk would be smaller. But it doesn't always have to be that way. Offloads can be started for various reasons such as structure events, recovery, and offload failures on other systems. So the worry is warranted. Now he tells me! Would you please explain to the IBM pricing people that their PLSC pricing schemes make customers do this which is absolutely contrary to the parallel sysplex design points?!? I'm not sure I have that much sway, but I definitely sympathize with the ironic nature of the setup. Art, As long IBM marketing dangles the carrot, coroporate IT will continue to support that, and only that, which is necessary to save $$. Shamplex has become part of the nomenclature... As for where support to restrict offload locations, this too was proposed by a poster last year, and so well-written that some of us ran to the books to read what we thought we missed! I would definitely make use of the feature. In the meantime, I'm looking into RACF profiles to prevent connectors on non- owning images, which in turn restricts offloads. That will only work so long as I have a RACF database per subplex. I reckon we'd better have SMS sorted out before we start RACF data sharing... I think the marketing solution would either be more restrictive or more costly. But perhaps there are a few things that can be done with existing functions that might help. RACF might help. If you can prevent logstreams from being used on systems with RACF or prevent data sets from being allocated that have log stream data set names, that might avoid the contention. Turning off logger would do it too, but probably not ideal. This may have been discussed before, but have either of you considered using SMS classes to fence test and production dasd from each other, and use the LS_xxxClas / STG_xxxCLAS log stream parameters to separate test and production log streams? If a production log stream accidentally connected on a test system, it might be able to get to the right dasd pool, and something truly shared like operlog might work for the whole plex. In V1R8 logger did add an option to separate test and production work on a log stream basis, but it was intend for clients who wanted to run test and production work on the same system. Logger sets up separate tasks for test and production work, and specifying the GROUP(TEST) or GROUP(PRODUCTION) option on the log stream definition will tell the log stream wich set of tasks to use. There are also restrictions enforced, such as a test log stream can't connect to a structure with a production log stream connected to it. It also prevents test log streams from using more than 25% of the structures. The goal was to prevent TEST log streams from harming PRODUCTION log streams. However, this doesn't help clients who want to separate workloads on a system basis. Is there a reason for such a stringent separation of DASD? Is it for failure prevention? Does accounting data get messed up? It sounds to me like a completely separate sysplex is out of the question, because it costs more than extra set of systems in an existing plex. Maybe it would help if I understood what's being walled out and what's being walled in. -Nick Jones Logger L3 -- 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: Fw: LINUX on the MAINFRAME
I have been interested for quite a while in running Linux on the mainframe. I'd like to share a little about the IBM Linux group we had for a while in Milwaukee. This group has been meeing 2 or 3 times a year for 4 or 5 years. I haven't seen a meeting for at least 6 months, if I remember correctly. IBM sponsers the group, and sets up the meetings. The thing that struck me most about the group is that there seems to be a far greater interest in running Linux on the mainframe than actual shops that run it. I thing we normally got 20 to 40 people who showed up at the meetings, usually for a half a day. There are some shops that run Linux on z in Milwaukee, but not that many. As I've said in the past, when I was working at PH Mining, we investigated running Linux in an Lpar. For what we would have used it for, it just didn't make much sense. All of the Unix servers we had were paid for, and taking the function off of a paid for box and running it on the mainframe didn't make a lot of financial sense. It makes a whole lot more sense if you have a few hundred, or even 20 - 40 Unix servers that you can dedicate several engines on a mainframe and run them under VM. That might work financially. Having just 1 or 2 lpars running Linux on z probably won't save any money. I also took a 3 course Linux Administration course from a local technical college. I installed Linux on my laptop with dual boot. It had a 10 gig partition, which at the time worked great. It was really helpful to be able to try out the commands as I read about them. Alas, that was a Windows XP machine. When I had some problems right before the warrenty expired, I took it in and they applied the standard fix - reload the hard drive, wiping out my Linux partition. I never bothered to reinstall it.

Re: LINUX on the MAINFRAME
Kurt Eastwood 04/13/10 2:34 PM Is anyone running linux on their mainframe? As of last report about 1,300 IBM customers. If so, how are you running it? standalone? under zos? etc? Most are using z/VM, but some of the biggest in the world run in LPARs to avoid the (minimal) overhead. How is installation and maintenance of linux and system while running linux on mainframe? Totally different from anything you're used to as a mainframe person, but totally familar to a midrange Linux admin. Are there any good redbooks or other documentation on installing and running linux on the mainframe? http://wiki.linuxvm.org/wiki/Relevant_IBM_Redbooks http://linuxvm.org/redbooks.html http://linuxvm.org/Present/ Are there any training course on doing this? IBM has some, but you can get the equivalent of that and a lot more at SHARE (coming to Boston in August) or IBM's Technical University (formerly System z Expo, coming to Boston in October) or WAVV (which just concluded for this year).

Scheduling Environments Sanity Check
We are considering using scheduling environments for the first time and are concerned that we might be over-doing it a bit. In a test and development LPAR, we have 16 test/development environments that each consist of 3-8 CICS regions, 2-5 ADABAS instances, and a connection to a DB2 subsystem. The total is about 100 CICS regions, 80 ADABAS instances, and 6 DB2 subsystems. To cover any possibility, we would define a scheduling environment and resource for each of these address spaces (186), plus a scheduling environment corresponding to each development environment (16). We believe that this covers the spectrum of batch jobs that might need anywhere from a particular CICS region (open/close files) to an entire development environment (regression test job streams). Is this a reasonable approach or overkill? We would appreciate your comments and suggestions as we don't want to create a monster.

Re: MFNetDisk will be a free product soon.
Shai, Great news for me, I know you had some success with a company in Perth, Australia and they are delighted with the product. Free is a bargain!

That mean you will be able to work without the limitation of number of devices. Why I am doing this: 1. I do not think that there is a space for another IO devices in MF. 2. The price of MF IO devices is very low and the competition is hard. 3. I think all my challenges with the product is over. 4. It is time only to support the product and I can not see any new feature in my product which I can create which will exciting the MF users. 5. As i said before, it was pleasure to dig in the MF as it pleasant to dig in the Linux and Windows. This product was developed first because I enjoy it. Just to remind, 1. MFNetDisk support emulation of disk 3390 and tape 3490 with data in Windows and Linux. 2. Mirror real 3390 disks. 3. Support EAV disks for emulation. 4. Tape manager in PC and MF. 5. Undelete Vsam and SMS and Non SMS files. 6. MFNetDisk CIOD (like IBM Pav for the emulation). 7. Backups of MFNetDisk disk with backup level of one track. and many more features..

Re: Non-SMS-managed LOGR offload data sets
Hi Barbara, we have a similar setupbut because we merged two production Parallel Sysplexes. history: 2 separate datacenters in same city. 2nd prod system had been CLONED from first and modified slightlythen had 10 years growth. We also had each datacenter being the DR site of the other. Sovereign RISK! - had to move DR site off country. Now no reason for 2 data centers in same city.so relocate machines from 2nd site to 1st. Then save money and merge the 2 separate Parallel Sysplexes into one. End up with 3 x JES2 MASplex / SMSPlex / HSMPlex in single Parallel Sysplex. (that 2nd site has been subplexed always...but only one subset had DB2.) Ok...had to have LOGR.reasons included heavy DB2 Data Sharing in both original sites. So we set up a pool of DASD that was accessible from every production system. Each SMSPlex was given a subset of that DASD to manage. So each disk volume has only one SMS owner. Set up common User Catalog, connected to each system MastCat. It doesn't matter which LOGR does the OFFLOAD.because the SMS managed offload dataset is placed onto the shared disk, and cataloged in common UserCat. Been operating like this for 12 months. Probably stay this way for a long time. The migration path from this BronzePlex to the ultimate PlatinumPlex looks almost impossible to complete.

Re: OPERLOG
IXG014E LOGSTREAM SYSPLEX.OPERLOG IS CURRENTLY IN USE IXG002E LOGR POLICY PROCESSING ENDED WITH RETCODE=0008 RSNCODE=0810 If IXCMIAPU tells you that IxgRsnCodeStreamInuse then you're not looking at the right definitions, either via command or in the IXCMIAPU job. When I had to redefine operlog logstream, the things I did were: 1. Check if any TSO user was stuck in SDSF-operlog. Cancel them mercilessly. 2. ro *ALL,V OPERLOG,HARDCPY,OFF Check via D C (better route this to all systems in the sysplex, too) that all systems complied and got rid of operlog. My LOGR policy is set up in such a way that I first delete the log stream, then the structure definition and then redefine them (first structure, then log stream). If the delete doesn't go through, *something* is still using the log stream. Bring out all the D logger commands to check again. But SDSF users were the only culprits in my experience. (Oh, and once things are redefined, v operlog back on.)

Re: Scheduling Environments Sanity Check
Hello Chester, we use Scheduling Environments. environment: Production systems in one Sysplex Development systems in a different sysplex. 1. the same scheduling environments are coded in both environments. Allows promotion of unchanged JCL from dev to prod. 2. Licensed products - every product that requires a license zap has a Scheduling environment coded. 3. Servers - code which requries a pre-requisite server task to be active has a Scheduling environment coded. (note: it may be that a group of tasks has to be active for the server to be active) 4. System - each system has a SYSNAME scheduling environment. Not usually used by application JCL. 5. Reminder - only one scheduling environment per JOB...this causes the most application developer angst. 6.Automation - most useful in turning ON/OFF scheduling environment resources when the pre-requisite conditions appear/disappear.

Re: Non-SMS-managed LOGR offload data sets
Answering all of last nights post in one: Mark, Anyway, I am commenting on it because the reason I had to use group name was due to 2 different DB2 subsystems on different systems in the same sysplex that had the same name. This particular system shares DASD, SMS, etc. but the applications aren't shared so there is no cross LPAR RRS considerations and I run this LPAR with GNAME= to the smfid. I beg to differ :-) (You're not surprised, are you?) Go to any system NOT connected to these log streams, preferably one that does not share DASD and SMS but *is* in the same sysplex. Use the RRS ISPF application and carefully look at all the input parms. (Do this at a time of little or no traffic, though.) Issue a browse command to one of the logstreams that *this* system is not connected to because it is NOT supposed to use this logstream. RRS will go out to logger with the definitions, LOGR in turn will say 'yes, I know that log stream' and have no problem whatsoever to *connect* to that log stream and read it out. Admittedly, the RRS application is smart enough to immediatly disconnect to the log stream after it got read. But if the log stream is big enough, it may take some time to read out the log stream. DURING THIS TIME YOU ARE EXPOSED TO THE RISK (sorry for the shouting). Obviously I could not do too much testing because any system with enough traffic to even have entries in the RRS log streams were production systems, and I did not want to risk a cold start. But it took several minutes (!) to browse the archive log stream (I did not dare use one of the non-optional ones) from the 'wrong' side. Art and Mark, I am severly hampered by solid non-knowledge of SMS details. I have heard all of that vocabulary, but I was never in a position to actually have to administer any of this, so all I can do is tuck away all of these details and show them to my admin when the time comes (I know that the admin does not want to change anything in the SMS setup, so he is not volunteering anything in terms of making it happen. I need all the information I can get to tell management what can be done, even if I don't understand the implications...) Bruce and Nick, our story is even worse. Parallel sysplex was introduced here in the late nineties, way before I joined the company. At the time *IBM* recommended three parallel sysplexes, sysprog sandplex for maintenance, applications development sysplex called TEST and production sysplex called PROD. For some reason (mostly hysterical), TEST and PROD were never separate plexes, so they shared DASD, SMS, RACF, TAPES, Automation etc. There were several incidents where changes to TEST caused problems in PROD. When I joined the company in 2001, there was a project underway for more than a year already to separate TEST and PROD because the autors had demanded a more secure PROD environment. This finally happened in 2002. Some time later we insourced a parallel sysplex from another company. Management decided to merge that 'foreign' sysplex with our TEST sysplex to save money. The 'foreign' sysplex did have completely different naming conventions and it did not use LOGR, so the merge was relatively easy. Took only about three months from conception to fulfilment. That 'foreign' subplex will be decommisioned soon. At this time we are again prone to paying more money if we keep TEST separate from PROD. I am in charge of the project to merge, and I have severe stomachaches for the LOGR part, especially as this time around naming conventions are identical *and* I have to find a way to make LOGR/RRS work on both subplexes because they already run there. Bruce, your setup sounds like the one I would *like* to have, because it will enable future LOGR applications (as I said, I would like to use SMF log streams). The migration path from this BronzePlex to the ultimate PlatinumPlex looks almost impossible to complete. Would not even be attempted here. Art, In the meantime, I'm looking into RACF profiles to prevent connectors on non- owning images, which in turn restricts offloads. That will only work so long as I have a RACF database per subplex. This will probably the solution that will be chosen here because it sounds like the least bit of work. Restrict connection to log streams by restricting the RRS ISPF application. It means that some sysprog TSO userids (we fortunately have different IDs in the subplexes, and RACF is separate, too) will need to get defined in the wrong RACF in order to explicitly forbid them to use this application (however I can do that). I think the problem with connecting to the log streams is that LOGR does it, and we have LOGR trusted. The RACF admin still has the scars from the time when LOGR was not trusted, so he does not want to remove that attribute. The problem I have with this is that this would only fill in the hole *that I know of*. What if someone comes up with some other way to make
