Re: Carrier Pigeon beats Internet Speed
You laugh ... I am working with a company that literally did this. They shipped a very large disk array to the central computing center and placed it next to the production array; synchronously copied all the data; found a quiet point on a Sunday morning and split the link; uncabled the array; shipped it across country to the BC site (Business Continuity now, not Disaster Recovery); they are in the process of cabling it up; will turn it on next weekend and away with go with a recovery drill.

Re: EMC DASD and Hyper-PAVs
Ron I am not sure what you have tried -- or how the actual DASD is configured. I assume it is some large disk array since you are involved. One more suggestion that might improve IOSQ is to stripe the VSAM dataset defined in DSNDB07. This would help if you ended up with a better spread across disk on the back-end array. You can get the VSAM striping with just an SMS change and delete/define of the data sets. Tom Moulder Ron Hawkins wrote: Martin, OK, you are referring to DSNDB07 as SORTWK. I never seen this before, and I think it's confusing. You may want to rethink this description as in DB2 V9 DSNDB07 is not just the DB2 SQL sort area, tables from DSNDB04 are now in DSNDB07 table spaces. Besides increasing the size of the Buffer Pool you would have to use the thresholds to disable pre-fetch. Given the nature of how these tables are used you would need to buffer the whole of DSNDB07 at its maximum, otherwise sequential IO without pre-fetch would just walk the buffer pool and cause some pretty inefficient IO and low buffer hit rates. The IOSQ Time would go down, but there would be some pretty horrendous batch and transaction elongation. I don't have the SMF data in front of me, but in this case we are talking around 20x3390-9 with 4K and 32K DSNDB07 in segmented areas across all these volumes and around 10 areas on each volume. IO was spread fairly evenly over the volumes. The 32K areas were far more active than the 4K, and were around half the space on each volume. A back of the envelope estimate says you would need to buffer half of the 20 volumes in order to get this locked in a dedicated Buffer Pool, which is about 40GB. I don't think the scale of buffering, along with the performance hit from disabling Sequential pre-fetch makes this the best way to reduce that IOSQ time.

(Often these buffer pools are dedicated to sort work data sets for management and reporting purposes. Indeed in my reporting code on the matter - fed by the DB2 Catalog - I could tell if this was the case.) It's entirely feasible to resize these buffer pools (using the normal DB2 buffer pool mechanisms) and to play with their sequential and update thresholds.

Re: Suggestions on how many Hyper PAVs to use per LCU
All I should have put more thought into this rather than just copying some text with the formula. John made me realize that I should have added my personal thoughts about this. Personally, I know of no one with the patience to calculate an alias value for each and every LCU in their shop. They might be different and God knows that the data might move around across LCUs during the course of a week and the SSCH value might be different today than it was yesterday. SO, having said that, I usually recommend taking the highest SSCH value for an LCU and using that value as a constant for all LCUs. This assigns the largest expected alias count for an LCU to all LCUs. If the data moves around, you are covered. Also, this formula typically results in much lower values for alias definitions than already exist, if you calculate a value that is too high, it doesn't hurt -- you are still using less than before. I mean think about it -- my previous recommendation for customers with mod-27s in an LCU was 3 alias to 1 base, so you would allocate 64 base devices and 192 alias devices -- with HyperPAV you can possible reduce the 192 down to 20. What a bargain even at twice the price. Tom John Ticic IBM-MAIN wrote: You are moving to a new box, so you need to look at your current peak I/O load, for each LPAR and calculate (on an LCU basis) how loaded your new LCUs will be. The method shown below is a good starting point, but pick your factor to cope with bursts of I/O activity. Since HyperPAVs are assigned on an I/O basis, you should look for the peak I/O workload (not the sum of all LPARs!). You should be conservative and use the RMF records (74.1 and 78.3) to verify your calculations (DASD device and I/O queing reports) after you have moved to the new box. Take a look at DS8000 HyperPAV case study (IBM techdocs) and also on our website for a white paper that will give you some background information.

Re: Hyper PAVs vs. Dynamic PAVs
I have a paper that documents the reaction time of WLM based PAV as opposed to HyperPAV. HyperPAV is instantaneous, in fact the IOSQ time in my test was zero for all intervals. Dynamic PAV controlled through WLM takes four minutes to adjust to a changing workload for a device and never gets the IOSQ to zero. The paper has been accepted for presentation at CMG in December of this year.

IBM has always admitted, unashamedly, that as of SYSPLEX, DASD sharing is problematic between SYSPLEX'. Also, for the exaggerator in the crowd, the maximum WLM interval is 10s, not 10m. - 10 seconds is the policy adjustment interval. But there are 2 algorithms controlling PAVs IIRC. One is to help goals and that runs about every 30 seconds. The other is for overall system efficiency and that runs about every 60 seconds. The problem is that they don't do much at each interval (each one is slightly different) so adjustments are very slow. Multiple devices can be adjusted, but no more than one alias will be added to a particular device during that cycle. So it can take a long time (maybe even 10 minutes) to get to where you need if there is a sustained increase in IOSQ. A good example would be when your onlines come up in the morning or when everyone walks into the office around the same time and starts doing work.

Discounts have been an issue for years now. It invariably leads to hard feelings on both sides of the negotiating table.

What means did the government agencies and IBM take to insure that done deals were actually done perhaps even today after the lifting of the suspension? Will this be a big enough story to actually affect IBM earning for the first quarter 2008? I have a lot of questions, but not a clue as to the answers.

Re: Shark to EMC
I would think that the only way to mirror in a multi-vendor environment would be XRC. The reason is because all the replication goes through the system mover and thus is at a higher level than the bare metal. Having said that, I would also add that the reason it can be done is the very reason you would want to seriously consider whether to do this. Performance of this configuration will not compare to PPRC. This would be a decision based on function desired not performance required. Everyone else has answered well what can be used to move the data from one place to another. The only thing I would add to that list is LDMF should you desire a change between disk models during the conversion. FDRPAS and TDMF will not move at the data set level to fully use larger model disks with data sets from many smaller volumes. LDMF will do this without an outage to the owning application. FDRMOVE is similar to LDMF in function not in the method of delivering the function and does require an outage to accomplish the move. There are many products that have been mentioned, hopefully, I have correctly described each one. They are all good products and deserve your analysis to determine if they will meet your needs. XRC is the only method I can imagine would handle mirroring as opposed to moving the data.

Re: Data Erasure Products
If you have EMC DASD, then you can contact them for information about three erasures offerings. The offerings are from low to high in terms of data erasure certification and government clearances. The highest certification level is an internal program that insures all data is erased and can not be retrieved. Be prepared also to spend some time achieving the highest level of certification. Hopefully the frame has been disconnected from the mainframe when you finally do this and so there is no impact on production work.

Go for it! You can absolutely leverage the better part of 2 gigabytes of memory just for DB2 buffer pools in V7. Pay attention to peak storage demands in DB2xDBM1 address space and remember that in V7 you can do some tricks like data spaces you lose in V8. Get more detailed advice on the DB2-L list. I think the level of concern may be to high here. 10G really is not that much even on z/OS 1.7 we had LPARs several times that size without any problem. There are some IEAOPTxx parms that can minimize RSM overhead on 1.7 that have been documented by IBM now but we found that made a difference on really large LPAR's 40G - 80G not 10G LPARs. Remember There is NO I/O like NO I/O! You can exploit extra real memory with products you already have in hand easily. SyncSort or DFSORT will both exploit more memory to improve performance easily. Some adjustments may help things run the way you want. Both SyncSort and IBM provide good advice as well as good software. Exploit VLF! Increase your cache size for CSVLLA and look at other exploitation of LLA/VLF. The best paging is no paging. Paging on z/OS is a waste of cycles put enough storage on you don't normally page. DB2! One of DB2's best defenses against I/O is sufficiently large buffer pools intelligently allocated with DB2 objects and thresholds. DB2 V7 is OK. DB2 V8 is much better at exploiting LOTS of storage. Spare storage? Are you planning on adding an LPAR? If not setup your HSA with plenty of room for dynamic growth and use the rest. At $8K/G or $10/G it seems wasteful to leave it idle.

Say we have a machine with, just to say, 10 Gb of real storage. Only 5 are used by the only LPAR defined (actually there's another very small LPAR, but it's real small), which is a WLC LPAR and often it's CPU capped. 5 Gb remain unused. I asked why, as I'd like to enlarge my bufferpools in DB2 (for instance). I've got these answers: - Increasing real storage increases cpu overhead to managed more memory blocks in a cpu-constrained machine. - Increasing real storage causes more workload so more chanches to hit WLC capping. - It's better to have some spare storage (5 Gb ?). Our workload is increasing and we have some occasional paging spikes. DB2 doesn't perform well due to too small pools.

Re: EMC DMX3-1500 and REFORMAT VTOC
What I have been told is that z/OS no longer uses the alternate tracks, so the reformat removes them from the VTOC.

Re: EMC DMX3-1500 and REFORMAT VTOC
Alternative tracks are actually provided for in the controller and were last used in the 3990-6. The advent of 2105 controller and emulation of it by disk arrays had no microcode to take advantage of/or use alternate tracks. When you reformat the VTOC, this process in no way compromises any data on the volume. However, I understand that if this has not been done before now that it might appear to be a nuisance issue.

Re: IBM obsoleting mainframe hardware
Barry I worked for a software vendor in the '80s that sold a 3270 optimization product for CICS. There were a large number of customers that would buy a version, never pay maintenance and hardly ever have a problem until they finally (typically after more than 5 years) went to a version of CICS where the product exits would not work because of changes to CICS. Then they would buy the product again to get support for the new version. Not everyone pays maintenance and there are times when customers save money by not paying maintenance. It all depends upon the stability of the product.

Re: 3390-27 PERFORMANCE
Frank, You ask about performance, so the answer to your question would be to use RAID 10. This will require more disk on the backend of the DMX-3, but will definitely give better performance. You will get the data for the 27 spread across 8 disks within the array by default which represents 4 striped disk mirrored. I hope that makes sense to you. The performance will be much better. PAV would be a concern from a number of angles. First, if you have more than one data set on the volume, then it will allow multiple I/Os concurrently. Even if you have only one data set on the device, you should look at DB2 to determine whether parallel processing is possible. You still might need PAV to support a single DB2 subsystem. Hope this helps.

Re: Multiple TSO logons
CC Did you ever want to take something back after you have done it? What I would give to recall the message that started this whole thing. So hard to explain. Offline to you would have had more meaning. Tom Moulder Chris Mason said (to Tom Moulder) If the proposed z/OS System Explorer is what I think it is - There's nothing proposed about it. The product exists already. It is possible that something with a similar name exists elsewhere, but Tom and I were referring to a BMC product. I know a little about it since it was my idea and my team that wrote it. judging from the use of the Microsoft Explorer word - it approaches the file handling which may be compared to what the *TSO extension* ISPF does. In other words, what z/OS System Explorer replaces is ISPF. Yes and no. It is by design very similar in function. But replace implies more than was perhaps intended. It does not attempt to replace user or vendor written ISPF application functionality. It is web server based rather than ISPF dialog manager based, so while there is (or could be) functional equivalence, it isn't really a direct replacement. It provides a more sophisticated (and familiar) point and click GUI interface for the main functions people typically use ISPF and SDSF for. The explorer GUI is easier for less expert people to use than ISPF. It runs as a JAVA app on the user's workstation and behaves exactly as you would expect a Windows or UNIX desktop application to work. And if you're familiar with the Windows File Manager, then you already know what it looks like and how to use it. z/OS System Explorer exploits some lower level environment in the client platform which may be equated to 3270 data stream analysis and construction in the server platform in the case of ISPF sitting on top of TSO. Well this particular z/OS explorer is contains an embedded Apache web server. You point your favorite web browser at the URL and away it goes. All of the client UI interaction flows over HTTP. In other words it's rather tricky to draw parallels even if the end-user is performing much the same functions with the proposed z/OS System Explorer as with ISPF. Yes. It is functionally similar and probably easier for most people, but not the same thing. No flames please, I know there are ISPF experts out there, I may even qualify for that term myself :-) We were trying to address the question of what do you do when your new generation of users reel back in horror when you ask them to logon to TSO? Even the ISPF cognoscenti would probably agree that newbies find it a rather user-vicious environment compared to what they are used to. I'm not sure remov(ing) the need for VTAM in the middle of things is much of a key distinction to mention compared to all the other necessary changes. True. OTOH it would have been absurdly difficult to accomplish the same thing using VTAM. Possible certainly, but not worth the effort. CC No virus found in this outgoing message.

Re: Cloning DB2 using Flashcopy
Tony I am not familiar with Flashcopy, so I have not made any posts on this thread. However, from a design viewpoint, here is what you might consider. When you are ready to cut to production, snap a copy or backup of all the volumes including the ICF catalog. Perform your conversion and if all goes well then you have no need of the copy you made. If for any reason you need to start over, turn the copy job around and copy the backup volumes to the production volumes. This will overlay all the work you have done, put things back to where they were when you started and all your catalog issues will be solved. Try to implement in production again. If you still have failures, you always have the beginning point to fall back on. The main drawback I see to this is that it will take more time to copy the backup data and overlay the production volumes than simply varying devices offline and online. However, you never touch the backup volumes, except to read them in during a restore operation to get back to where you started. I do not know if the Shark supports this or not, but at EMC these backup volumes could be used as input to the restore operation without ever bringing them online to the host. I hope I have actually understood your plans and desires. From a DB2 perspective, you should have no problems with the procedure you have outlined assuming that you include all the volumes that are touched by DB2. This would include the BSDS data sets, the active logs and archive logs if they are on disk, the DB2 catalog, the ICF catalog and the application data.

Re: DSS EXCP counts
Barry I just got my interest piqued a little by your question. So, here is what got my interest -- why would you take full volume dumps if they haven't changed in months/years? Tom Moulder -Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Schwarz, Barry A Sent: Thursday, May 10, 2007 2:06 PM To: IBM-MAIN@BAMA.UA.EDU Subject: DSS EXCP counts Can someone give me a hint why the EXCP count for a full volume dump for an unchanged volume would occasionally vary by ~400 between one execution and the next. I run a set of jobs weekly to dump just my system packs to tape using DFDSS. Several of the packs, such as the DLIB volumes, haven't changed in months/years (2.10 is out of support). Most weeks, the EXCP count is very close to last week's count for each volume. Once in a while, the count will jump up for a one week (or occasionally a few weeks) and then return to normal. When it happens, it seems to happen for all the jobs. Some of the packs are pretty full and the delta is less than 10%. But my SMPPTS dataset is alone on a pack and has been almost empty since my last accept run. Its normal EXCP count is 700 and an increase of 400 is a significant percentage. The times for the jobs do not show a corresponding delta. It doesn't seem to make any practical difference but it has piqued my curiosity. No virus found in this outgoing message.

Re: MIDAW and EMC
Roland I may be corrected, but I do not know of anything in the implementation of MIDAW that was hardware related. The hardware may have some modifications to address the changes to the CCW. However, the EMC Symmetrix product family support MIDAW and have since last year. The benefits are primarily a function of the changes within Media Manager and provided to all users of EF data sets of which DB2 may be the largest user. I certainly would like to be corrected if the similar benefits are not achieved using EMC hardware. I have not personally checked to verify this, but have no reason to believe that you would not get the same benefit.

Re: Systems Programmer job posting
The aspects of W-2 and how it would work depend upon whether you are union or not typically and since this is military I would assume that union is not present. That being said, it would seem that they would have to give at least the same benefits to a W-2 that they give to a contractor. You could get into a situation where you have to pay a portion of the benefits. Everyone seems to be doing that these days. If you choose the W-2 option, what would you actually have to live on? Let's take out an estimate $15k for income tax and another $12k for FICA and Medicare assuming the top end figure of $78,200. So now you are down to $51,200 to live on. I know of several young families of 3 to 5 in the family that are making it on that amount as the gross. It could be worse. If this is straight up truth, I would take the hourly W-2 rate. Since this specifically excludes 1099 work, there is very little that you can do with expenses to reduce the tax burden and you immediately become responsible for the entire Social Security burden out of the $63k.

Re: IBM 1Q2007: System z Revenue Growth +12%
Snip Does the number of boxes matter? Not really, no, because of greater capability. For most customers two is a very good number of mainframes to have (assuming in-house disaster recovery capability). You can get an awful lot of capacity in a single frame. What I suspect is happening is that a lot of customers (and more customers) are buying more MIPS, more memory, more coupling facilities and Parallel Sysplex, and more zAAPs/zIIPs/IFLs, and they're getting all that in fewer footprints per data center because fewer can deliver more capacity. Snip Thank you Timothy for informing us that the same customers and maybe a few new ones are running fewer z machines to do more. Why are they ordering bigger machines? Could it be the introduction of DB2 Version 8 or 9? Trying to run Websphere on z? Software is a good market for IBM because it also drives hardware revenue. I don't know how to figure this into the profitability of any particular software product, but it is definitely there. Tom Moulder My opinions. -- No virus found in this outgoing message.

Re: zAAP Eligible Work
Something else to consider are two IEAOPTxx parameters for WLM control of zAAP eligible workloads. IFACROSSOVER controls whether standard CPs will be used for zAAP eligible work. If YES (the default), then standard CPs will be used along with zAAP CPs. zAAP CPs will be preferred, but standard CPs are not excluded from consideration based on workload. If NO, then standard CPs are not considered for zAAP eligible work unless there are no zAAP CPs present. IFAHONORPRIORITY controls the workload priority settings for zAAP eligible work that is executed on standard CPs. If YES (the default), then all work on a standard CP will execute based on WLM assigned priority. If NO, then all zAAP eligible work that is assigned for execution on a standard CP will be scheduled at a lower priority than non-zAAP eligible workloads.

Re: IBM to the PCM market(the sky is falling!!!the sky is falling!!)
R.S. I didn't realize this until last December, but there is something you can do with your Oracle licenses -- move them to another CPU. Strange as that may seem, Oracle licenses are by the number of CPUs, so a PC with a dual core Intel pays twice as much as a single core Intel. Likewise, a z/9 running Oracle on z/Linux (here we go again Ted -- Linux will rule the world) under z/VM on a single IFL costs the same as a PC. In fact, you can transfer the licenses around, so you could take a PC out of commission and use the Oracle license to run on z/Linux. John Anderson who works with IBM has made a great practice out of moving 100 Oracle licenses for various server farms onto single IFL on z/Linux. You never get back the one time charge, but you do save on the 22% annual maintenance for the license.

Re: EMC's DASD replication
Ping Perhaps it would help if we knew what you were trying to accomplish in disaster recovery and the reason that EMC displays the WTOR and requires a reply. There may be another way to accomplish your purpose that does not require the replies. Two general observations might also help you. The customers that I have worked with for disaster recovery operations have used some form of SRDF and that process does not require any operator replies to function properly. Especially not for thousands of individual devices. Also, the restore operation when it is used as a full volume restore is a destructive operation that requires verifying the VOLSER. You want to think carefully before you overwrite standard volumes without some process to verify that the source and target were actually paired together at one time and represent the same volume.

Re: Is anyone still running..........................
snip Re: DB2 prices, by the way, what you describe isn't necessarily so either. VWLC means a lot of DB2 customers have seen their monthly license charges decrease (around about Version 7 for most shops I think, depending on when their last OS/390 LPAR disappeared and when they cut the first SCRT reports). The zIIP technology is another reason you might see a decrease in DB2 MLC starting with Version 8. unsnip Timothy I have worked with many shops making the leap to V8. I have never seen a shop yet that saw a decrease in costs for V8. Not even with the changes you've talked about. The zIIP will only offload a narrow workload and for most customers this has little impact on costs. Perhaps V9 will expand on that list, time will tell. From what I've seen, VWLC is not the panacea that you paint for DB2. It has been helpful in reducing costs elsewhere, but not on the charges for DB2. I have seen customers segregate DB2 to reduce software costs, but it is done at the expense of flexibility and potential availability options. Because of the many changes associated with DB2 Version 8 and hardware changes associated with the version and now available to support that version, I have found it extremely difficult to determine the difference between CPU usage and costs when comparing V7 and V8. There are a good number of customers I work with that have upgraded processors in advance of V8 to support 64-bit processing. When making performance changes I try to limit the number of changes at the same time to measure the differences of the change. The number of changes with V8 make it difficult to determine exactly what changes made what difference in usage. What I have also seen is that DB2 SQL tuning has the greatest potential for cost savings. Much greater than any software pricing could ever produce. There is a lot of low hanging fruit when the customer has written the SQL, it gets a little harder when you have a purchased application and can not change the SQL. It is always possible to reduce costs. V8 offers several ways to reduce CPU usage of the SQL, some require SQL changes and some do not.

Re: Is anyone still running..........................
Edward I first made an assumption that like all software from IBM new versions would have an increased MLC. This has been true for DB2 for as long as I can remember. However, my initial checking seems to indicate that moving from OS/390 V2 to z/OS V1 could possibly result in decreased MLC. Any customer would have to check with IBM and get an MLC report containing all the required components to insure accuracy of the pricing. There has never been an increase in MLC when moving from one rev to another as long as the version did not change. I apologize to IBM for my assumption that appears to be incorrect.

Re: V2X2 vs. Shark (SnapShot v. FlashCopy)
Timefinder/Mirror is the software that is required to control the Business Continuance Volumes that are defined in the BIN file of the Symmetrix. This has been discussed at a high level in previous posts, however, it is probably worth stating here that all RAID configuration specifications for the pair of volumes (Standard and BCV) is controlled within the Symmetrix device itself. However, a change to the condition of the pair (i.e. mirror Established or mirror Split using EMC terminology) is controlled by TF/Mirror from the host through commands to the Symmetrix. Inside the Symmetrix, there is a requirement for enough storage to be allocated to support a complete copy of both volumes. Both volumes must be defined as the same size. From my point of view, the most valuable feature of this arrangement is the ability within the Symmetrix to perform what EMC calls a Consistent split of the mirror across any number of volumes. The Split of the mirror between all volumes is I/O consistent at a single instant in time. This is especially good for database subsystems that have related data across a large number of volumes. The user can break off a copy of a subsystem assuming that all related datasets are contained upon a select set of identifiable volumes that exist in this mirrored relationship -- Standard to BCV. The resulting volumes that contain the subsystem appear as though the subsystem was simply brought down by something as simple as a power failure and the subsystem is perfectly capable of dealing with restart after a power failure.

Re: Mainframe vs grid
I read the article and it did not contain any information concerning the size of the mainframe that is being compared to the grid. I have seen detailed analysis of grid computing versus the use of a parallel sysplex in z/OS and the z environment compared favorably when using its capabilities. This article talks about the mainframe using VSAM files and some IMS. It seems to me like they needed to be using less VSAM and more IMS, perhaps FP to get the throughput that was required. The mainframe has plenty of options for processing large amounts of data in parallel -- similar to what this customer achieved through the use of a grid -- that provide for faster response time. Also, this article mentioned that the application changes were difficult and time consuming and that the newly written application could handle changes more quickly. This too could be handled with good application design on the mainframe. So -- what is your point -- this appears to be a project where everyone was comfortable with the programming environment of a grid and developed an application that maximized it strengths to produce a good result for the client. That is great for the client. My caution is to take this article and imply that anyone else would achieve the same result by using the same technology and that the same result could not be achieved using a mainframe. How about some basic math on the numbers presented -- one mainframe versus the grid of more than 120 Dell servers to produce an application that finished in 65% less time. Did they compare the cost and performance of three mainframes loosely coupled as a sysplex to determine what the performance would be? Let's see, three versus 120 and the three could probably outperform the 120? Don't get me wrong, I know that it is easy to second guess a solution. However, this company spent a lot of money on the completed solution. The article even says that money was in third place on their priority list. So, cost of the solution did not rule out the mainframe. It appears from the article that a single mainframe does not scale as well as 120 Dell servers. I think I could have made that leap of faith without an elaborate test. I walked away from the article with the impression that good technicians on this project did not want to use the mainframe and developed a good solution without it. However, this does not tell me that the mainframe could not have done this job equally as well had the project been composed of mainframe technicians that knew how to make the environment scale and perform equally as well as a grid. Just my bucks worth. So many words could not be worth two cents, could they? Tom Moulder snip Slashdot had this article today: http://linux.slashdot.org/linux/07/01/05/0538224.shtml IBM touted 2006 as a resurgence year for the mainframe, but not so fast. At R.L. Polk and Co., one of the oldest automobile analytics firms in the U.S., an aging mainframe couldn't cut it, so the IT staff looked elsewhere. Their search led to a grid computing environment - more specifically, a grid computing environment running Linux on more than 120 Dell servers. The mainframe's still there, apparently, but after an internal comparison showed the Linux grid outperforming the mainframe by 70% with a 65% reduction in hardware costs, Polk seemed content banishing the big box to a dark, lonely corner for more medial tasks.

Re: Just another example of mainframe costs.
I would hate to get a reputation as anti-mainframe -- like CC --, but the discussion concerning PSI and their use of Intel Xeon processors to emulate/simulate/whatever they do a z/Series machine should have made everyone realize the power in the non-mainframe chips. And when you get down to discussing relative I/O performance, just remember that every disk manufacturer mentioned on this list uses a *nix-like chip and operating system to run the disk subsystems that provide the I/O performance you are talking about. I like the mainframe, z/OS and all of its associated subsystems. It has provided me with a good living for a long time. The question concerning why the costs of a z machine are considered so high is an interesting one to ponder. There can be many culprits named for this phenomenon. I personally believe that software costs (including and especially IBM) should be at the top of the list. What amazes me is that the costs have not been reduced significantly enough to stop the movement to other platforms. One thing I have noticed is that personnel costs for z professionals has not increased. As more of us retire one would think that trend would have to change because of supply and demand. I guess time will tell if that happens or not.

Re: Data replication at a remote site - elementary doubt
Jeffrey brings up a good point to remember when involved with remote mirroring of data. There are some errors that occur, perhaps especially because of program errors, where you simply do not know that the data is bad until well after the time for asynchronous mirroring to have completed. In this case, you have two copies of the bad data. There is a value to have point in time copies that are taken before major updates take place in the application data that can be used as recovery points should you encounter program problems that result in corrupted data. Also, these situations can be handled with Log analysis software through surgical repair of the data as opposed to normal recovery processes.
