Re: IEA061E replacement ASID shortage
Unfortunately I have no control over what runs in production, if I could spend the time and effort to address this one issue, i could, in the real world leadership is more concerned about how many tickets we resolve per week and how our time is accounted for and working BS issues. that's a rude statement, in my career as a sysprog, 30+ years I can count on one 4 fingered hand the number of outages I've had on the systems I support, most of this time without a health checker, the health checker was me and my team.

Re: IEA061E replacement ASID shortage
Peter, This topic has appeared a few times on IBM-Main. Search the archives and pay special attention to posts by Peter Relson and Jim Mulder on this subject. You can also look up the IEF352I message to help in your understanding. For those address spaces that are issuing this message, are you sure that they need to be stopped? Most cross-memory server started tasks are designed to stay active for the life of the IPL. Closing them down for overnight housekeeping is normally overkill. Does the software running in these address space support using REUSASID=YES on the start command? Ask the vendor or look in the appropriate manual for the product.

Re: IEA061E replacement ASID shortage
15 is way too low for a site that runs address spaces that are not restartable, or at least are not restarted to reuse the reserved ones. There is only a small overhead for setting a bunch up and it's not worth the chance to IPL to not specify something big. 2500 is not unreasonable if you have a lot of address spaces (like SAG stuff) that for some reason is not started to reuse the old spaces.

IEA061E replacement ASID shortage
Hello As per the manual The number of ASIDs available for replacing non-reusable address spaces has dropped below 5% of the value specified in IEASYSxx with the RSVNONR specification. Is there a way to know which resources causes this depletion of replace ASID ? The RSVNONR value is 15 in our system We just did the IPL a week before and it caused this message As per MXI The total ASID number shows 3000 Number of free ASID : 2815 z/OS 2.4 Any pointers are appreciated Regards Peter -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Re: REPLACEMENT ASID SHORTAGE
As spoken/sung by Pete Seeger - Seeds: The Songs of Pete Seeger, Vol. 3 Disc 1 ENGLISH IS CUH-RAY-ZEE English is the most widely spoken language in the history of the planet. One out of every seven human beings can speak or read it. Half the world's books, 3/4 of the international mail are in English. It has the largest vocabulary, perhaps two million words, And a noble body of literature. But face it: English is cuh-ray-zee! Just a few examples: There's no egg in eggplant, no pine or apple in pineapple. Quicksand works slowly; boxing rings are square. A writer writes, but do fingers fing? Hammers don't ham, grocers don't groce. Haberdashers don't haberdash. English is cuh-ray-zee! If the plural of tooth is teeth, shouldn't the plural of booth be beeth? It's one goose, two geese. Why not one moose, two meese? If it's one index, two indices; why not one Kleenex,two Kleenices? English is cuh-ray-zee! You can comb through the annals of history, but not just one annal. You can make amends, but not just one amend. If you have a bunch of odds and ends and get rid of all but one, is it an odd or an end? If the teacher taught, why isn't it true that a preacher praught? If you wrote a letter, did you also bote your tongue? And if a vegetarian eats vegetables, what does a humanitarian eat? English is cuh-ray-zee! Why is it that night falls but never breaks and day breaks but never falls? In what other language do people drive on the parkway and park on the driveway? Ship by truck but send cargo by ship? Recite at a play but play at a recital? Have noses that run and feet that smell? English is cuh-ray-zee! How can a slim chance and a fat chance be the same When a wise man and a wise guy are very different? To overlook something and to oversee something are very different, But quite a lot and quite a few are the same. How can the weather be hot as hell one day and cold as hell the next? English is cuh-ray-zee! You have to marvel at the lunacy of a language in which your house can burn down While it is burning up. You fill out a form by filling it in. In which your alarm clock goes off by going on. If pro is the opposite of con, what is the opposite of progress? Well, English was invented by people, not computers And reflects the creativity of the human race. So that's why when the stars are out, they're visible, But when the lights are out, they're invisible. When I wind up my watch I start it, but when I wind up this rap, I end it. English is cuh-ray-zee!

English contains a number of words and phrases that can mean either A or ¬A in a context-sensitive fashion. The verb to enjoin can, for example, mean either 1) to require or 2) to forbid. The Alexandrian rhetoricians wrote about the use of such treacherous words in ancient Greek, and I suspect that they may occur in modern Dutch too. --jg On 8/14/12, ibmmain nitz-...@gmx.net wrote: All but impossible means very nearly impossible, impossible without very great difficulties, and the like.

Re: REPLACEMENT ASID SHORTAGE
Ask IBM to fix DB2 and MQ to use reusable LXs Since DB2 does not use a reuseable LX, it cannot be called from a job using a reuseable ASID. Most annoying. While I agree with the sentiment, I would like to correct the terminology a bit... Running out out LXes and running out of ASIDs are two separate, mainly unrelated, problems. z/OS provides both reusable ASIDs, and Reusable LXes, as separate things, which happened to be implemented around the same time. So I would reword your comments to say: Ask IBM to fix DB2 and MQ to use reusable ASIDs. I have been told that the DB2 and MQ development view is that it should not be necessary to frequently recycle the DB2 and MQ server address spaces, so this should not be a large contributor to ASID shortages. Since DB2 and MQ use the ESAR instruction, they cannot be called from a job using a reuseable ASID. Most annoying. I have been told that their are many instances of ESAR to the caller's address space throughout the DB2 and MQ code, so there would be considerable cost to convert all of these to ESAIR.

Re: REPLACEMENT ASID SHORTAGE
You went on a OCO rant without answering my question. I looked in the POPs manual and found the two differences between the use of ESAR and ESAIR - * In the EXTRACT SECONDARY ASN AND INSTANCE operation, the SASTEIN, bits 0-31 of control register 3, is placed in bit positions 0-31 of general register Rx. In the EXTRACT SECONDARY ASN operation, bits 0-31 of general register Rx remain unchanged. * Operation exception (if the ASN-and-LX-reuse facility is not installed, ESAIR only) The second is only an issue if the minimum support level for DB2 and MQ is machines without that feature - Otherwise it is a non-issue. Just adding a check to the launch modules to test for the feature would not work since a negative result would need to not have the change made to the code. Hopefully all the machines you run the code on would have the feature OR you could add the requirement to the new version that has the ESAIR code. As to the first difference, does the high byte of register Rx (the referenced register in the instruction) affect the code? - IOW: Do you look at it or just use the result as supplied independent of if it came from a ESAR or ESAIR? Only once these questions get answered does the issue of OCO come into play since we have no access to the code to look at. It is my contention that so long as I can swap a ESAR with a ESAIR (and know that the ESAIR is supported) then just doing a mass replacement of ESARs with ESAIRs should be doable with minimal effort. Just use ISPF and concatenate the library with the source code behind an empty PDS (or PDSE). Do a mass find/replace on that concatenation and any member that uses the ESAR command with end up in the empty PDS with ESAIR commands being used. Compile that, convert the object decks into a SYSMODs, and feed it to SMPE and you have an upgraded version of the load modules. I know the above is simplistic but it amounts to a good model of the sequence of steps that would be needed.

Would it not be possible, without breaching OCO, to provide a more quantitative, confidence-inspiring statement than . . . there would be considerable cost to convert all of these to ESAIR. I see that I said ESAR-ESAIR when I meant SSAR-SSAIR. Also, there is PT-PTI to consider. Note that the xxI form of these instructions use the high order half of a register, so there may be additional complexity using them in code in situations where the high order half of the register was expected to be preserved. Also, if the program still intends to support the z800 and z900 processors, it must be dual pathed, since those processors do not implement the ASN-and-LX Reuse Facility. And dual pathing is also necessary if the program intends to support a release older than z/OS 1.6. I do not know to what extent any of those consideration might apply to DM2 or MQ. I do not have DB2 or MQ internals knowledge, or code access, so I cannot provide a more quantitative statement. I am just paraphrasing the kind of responses I have gotten when I have asked the question. I am also not in a position to evaluate the priority of this requirement vs. the other requirements for these products. Customers for whom this is an issue should (as always) consider submitting requirements through the usual venues. Customer requirements have considerably more influence over product development priorities than I have (especially with regard to products owned by a different division of IBM than the one which employs me).
