Re: DB2 Fetch Behind the Scenes
DB2 does not necessarily materialize the whole result set in every situation. Since the DB2 optimizer knows nothing about the loop in your program it can't incorporate your intentions. Try using FETCH FIRST 50 ROWS ONLY clause or OPTIMIZE FOR 50 ROWS clause in your cursor. Wild card at the start of a like predicate tends to be problematic more often than not, avoid it if you can. Try limiting your query by other criteria if there are any. Generally speaking the answer to give me anything / everything is not computationally easy. HTH Mohammad *** original post * Note: I did attempt to send this to the DB2 group but it bounced back at me so I'll send it here to IBM-MAIN and attempt to figure out what went wrong with my DB2 auth. DB2 internals type of question. ISSUE We have a process that returns table rows matching on a masked name. The LIKE predict is used with a wildcard to return the matching names. We, not surprisingly, are experiencing time outs in our CICS region when the mask is rather open ended. For example: LIKE %AND%. There are several million names in the database. We are now limiting the cursor to stop after 50 names have been returned but we still see some time outs. MAIN QUESTION Does the cursor, prior to returning any results, compile all the results before hand? Meaning, even though we have limited to cursor loop to 50 is it still compiling the thousands of results in the background? Would at FETCH FIRST help in this case? Something else? ADDITIONAL QUESTION Is there a better method than the LIKE predict? The name column is part of an index and is the lead column. We are contemplating removing the beginning wildcard. LIKE 'AND%'. This we figure should help but doesn't give the user as much flexibility. Any insights on main question would be much appreciated.

Re: Lines, Bars and ... mini-bars???
The confusion is caused not merely because people made up their own nomenclature but also because the thing keeps changing. Once upon a time for memory above 2G there was no allocation in the 2G - 4G range and this area was not for executable code. Now the allocation normally is beyond 32G unless you ask for it then you can get memory in 2G - 32G range as well. Executablity seems to be coming as well. Taken to it's logical conclusion the bar will in effect be reduced to a mere line with no width at 2G boundry. Oh well ... what's there to complain about. Mohammad So... what exactly is the bar?

Re: performance of dynamic memory allocation in linkage section
Unless you have to output all this data e.g. write it to a file, print it to a report etc. DO NOT move all this data to the program. The cross memory move from DBM1 to program address space can be prohibitive and that's not even accounting for the processing cost. If there is something to be summarized summarize it in the database engine rather than in your program. Don't move any data to the program unless you absolutely have to. SQL is a lot more than a record oriented access method so make use of its capabilities. If you have DB2 9 or 10 you might benefit from the use of native sql stored procedures.

There are many arrays which are loaded from DB2 tables. The number of occurrences for all these arrays which vary from run to run. Hence we thought instead of using working storage section for these arrays, we will use linkage section. We are using LE module CEEGTST to get heap storage and allocating linkage storage memory dynamically. We have defined the array as OCCURS 1 TO 1 TIMES DEPENDING ON ws-table-size. We calculate ws-table-size in the start of program and get only that much of storage from heap. The aim is to limit the program's memory requirement and improve performance. But the flip side is that this main program calls many called modules for each record processing. So for all the calls main program has to call the sub-routine with the entire linkage section. The estimate is that the total linkage section of the main program will not exceed 5 to 10 MB. For a large processing run, the total number of calls can be around 50 million. Another way would have been to declare all the arrays in working storage with large occurrences (e.g. OCCURS 5000 TIMES) and make it EXTERNAL. Then there will not be any need to pass data in the call and all the programs will get the required data. But this will also increase the storage requirement of working storage. We are not able to judge which method is best for performance in the long run. Coding both ways and testing will be time consuming and we do have that much time in the project.

V7 is a 31-bit app therefore everything is under the bar there. Increase the pool only if you have enough real memory to go with it otherwise results may not be to your liking. Even if there is enough real memory to go with it do check that you are not taking away virtual storage from another critical part of DBM1 address space e.g. virtual buffer pools, remember it all has to fit in under 2GB. This increase can help with DB2 performance if you are encountering many RID pool failures DUE TO POOL SHORTAGE but doesn't help if the failure is due RDS RID limit.

Re: Can CICS region share more than one processor
Hi Don Thanks for the reference from the manual. BTW this confirms rather than contradict my understanding that DB2 work never ran on main (QR) TCB. Before OTE exploitation DB2 work used to run on subtask thread TCBs, now it runs on L8 TCBs. There was always this much concurrency for applications using DB2. If you want to quantify the benefits of OTE you will have find what ADDITIONAL work is running on L8 TCBs rather than running serially on QR TCB. Regards Mohammad On Thu, 20 Aug 2009 11:25:38 -0400, Don Deese don_de...@cpexpert.org wrote: Hi Mohammad, I hope that the following (snipped from the CICS DB2 Guide) will help: snip The CICS DB2 attachment facility includes a CICS DB2 task-related user exit, DFHD2EX1, that is invoked when an application program makes an SQL request. It manages the process of acquiring a thread connection into DB2, and of returning control to the application program when the DB2 processing is complete. When CICS is connected to DB2 Version 5 or earlier, the CICS DB2 task-related user exit operates as a quasi-reentrant task-related user exit program. It runs on the CICS main TCB (the QR TCB) and uses its own subtask thread TCBs to run threads, switching to and from the subtask thread TCBs for each DB2 request. However, when CICS is connected to DB2 Version 6 or later, the CICS DB2 attachment facility exploits the open transaction environment (OTE), to enable the CICS DB2 task-related user exit to invoke and return from DB2 without switching TCBs. In the open transaction environment, the CICS DB2 task-related user exit operates as a threadsafe and open API task-related user exit program--it is automatically enabled using the OPENAPI option on the ENABLE PROGRAM command during connection processing. This enables it to receive control on an open L8 mode TCB. Requests to DB2 are also issued on the L8 TCB, so it acts as the thread TCB, and no switch to a subtask TCB is needed. For full details of the CICS DB2 configuration needed to support the open transaction environment, see Migrating to a different release of DB2 in topic 2.3. In the open transaction environment, if the user application program that invoked the task-related user exit conforms to threadsafe coding conventions and is defined to CICS as threadsafe, it can also run on the L8 TCB. Before its first SQL request, the ap plication program runs on the CICS main TCB, the QR TCB. When it makes an SQL request and invokes the task-related user exit, control passes to the L8 TCB, and DB2 processing is carried out. On return from DB2, if the application program is threadsafe, it now continues to run on the L8 TCB.Where the correct conditions are met, the use of open TCBs for CICS DB2 applications decreases usage of the QR TCB, and avoids TCB switching. An ideal CICS DB2 application program for the open transaction environment is a threadsafe program, containing only threadsafe EXEC CICS commands, and using only threadsafe user exit programs. An application like this will move to an L8 TCB when it makes its first SQL request, and then continue to run on the L8 TCB through any amount of DB2 requests and application code, requiring no TCB switching. This situation produces a significant performance improvement where an application program issues multiple SQL calls. The gains are also significant when using an enterprise bean, because when enterprise beans make DB2 requests, they require additional TCB switches to and from the enterprise bean's own TCB (see Using JDBC and SQLJ in enterprise beans: special considerations in topic 8.9).

Re: Can CICS region share more than one processor
Hi Don We seem to differ on how DB2 code USED to execute within CICS applications. To the best of my knowledge and belief DB2 code NEVER executed on the main CICS TCB ( QR ) and always had multiple dedicated TCBs defined for its use via RCT. I'm more than happy to be corrected but that's how I know it at least since I have been working with this stuff. Before OTE enhancements came along, on completing sql execution a task would switch back to main CICS TCB. The use of multiple concurrent CPUs was limited to DB2 code only. With OTE a task may not switch back to QR from L8 if it's thread safe. My point is that the increased concurrency is only incremental, sql execution was always concurrent. Therefore my question about the portion of L8 CPU time that is non-DB2. I hope that clarifies it ( or I get corrected ) Mohammad On Wed, 19 Aug 2009 10:48:38 -0400, Don Deese don_de...@cpexpert.org wrote: Hi Mohammad, I don't understand the relevance of your question within the context of Dr. Merrill's posting. Dr. Merrill was illustrating the concurrent execution of multiple TCBs (both the QR TCB and L8 TCBs) that would not have been possible prior to the OTE design. It is somewhat irrelevant as to whether DB2 CPU time was charged to a QR TCB or to an application TCB in past. The fact that the DB2 processing would have been executed in series off QR TCBs, but now executes in parallel with L8 TCBs is the important point that Dr. Merrill was making. Keep in mind that Dr. Merrill was responding to the OP query Can CICS region share more than one processor. FWIW, I have data from CPExpert users that show 10, 20, 30 or more L8 TCBs executing concurrently and using more than 100% of CPU (namely, they are using multiple CPUs concurrently for more than 100% of the time). This would not have been possible prior to the OTE design. As Dr. Merrill pointed out, there are 22 TCB types with CICS/TS 4.1, and several of these TCB types can have multiple TCBs executing concurrently. The number of current TCBs can be controlled by the MAXxxxTCBS in the SIT or in the JVMPROFILE Resource Definition. There are, of course, limiting factors inherent in the environment (for example, CICS monitors the amount of available MVS storage and will not attach new TCBs from the JVM TCB pool if storage is severely constrained).

Re: Java Heap/LE Heap DB2 9
I don't have any solution for your problem but have you looked at native SQL Stored Procedures ? They run in DBM1 rather than another address space using TCB/SRBs from client address spaces. They don't have to make cross memory calls for SQL execution. Native procedures invoked via DDF are zIIP eligible. Unless you have a lot of Java SPs already coded, I'd suggest that you take a look at this option.

Re: Can CICS region share more than one processor
Thanks Dr. Merrill for your illustrative example but I do have a question about it. Since L8 TCBs are used to execute DB2 code as well, what part of 10,298 seconds is for DB2 ? Since DB2 related code never executed on QR TCB anyway, that portion of CPU usage is moot for this discussion. The real question is how much of this CPU now runs on L8 TCB which used to run on QR TCB due to the aggressive OTE exploitation ?

I could NOT have been more wrong! Analyzing new CICS/TS 4.1 Open Beta data from a VERY aggressive OTE exploiter site shows (from their SMF 110, subtype 2 Dispatcher Statistics segments, MXG CICDS and CICINTRV datasets): Total TCB CPU in Dispatcher Records = 13,080 seconds Total TCB CPU in QR TCB = 2,776 seconds Total TCB CPU in L8 TCB = 10,298 seconds Total TCB CPU in all other TCBs = 6 seconds Aha, you say, OTE still doesn't help; the CPU time just moved from the QR TCB to the L8 TCB, so the capacity limit just moved from one TCB to the other, right? Wrong again. While the QR TCB can attach only a single TCB, these new TCBs can attach multiple TCBs; in fact, the SMF data shows that the L8 TCB attached a maximum of 22 TCBs, each of which is a separate dispatchable unit.

There are some cases that do need it. If a program is processing XML or Large OBjects ( LOBs - document images, video, audio ) the memory use baloons up pretty fast. If these are being used under CICS multiply by the number of concurrent transactions. There is only so much that you can fit below the bar so more data there means less of code. Channels and containers in CICS are already above the bar and have to be shuffled around the bar because COBOL can't address them where they are.

My bad, I didn't realize that the integer is optional and defaults to 1. I have always specified this value whenever I used this clause.

UDFs are no magic bullets and can hurt as well as help. For providing SELECT access to data outside of DB2, table UDFs provide a neat solution. As for the costs involved, this code runs in a seperate address space (which is started by WLM if not already there) under its own TCB thus requiring a task switch and cross memory move of data for every row accessed.

Anton, can you stop beating about the bush ?
Anton I asked you a simple question - why do you blame these failed conversions on IBM and / or DB2. But instead of listing your reasons for your assertion you came up with irrelevant questions like - Why do you think people convert to DB2 ?. When I insisted on getting some facts, you mentioned some papers available on the web ( see your message below ) which, I assumed, have the relevant facts. So I asked for links to these papers but now you can't provide these either. Looks like a case of the dog ate my homework.

I understand what you said, you are the one evading the question. Let me just explain the most important part : People do not use DB2 or convert to DB2 because it's the fastest and uses a lot of WLM. That was NOT my question. YOU posed this irrelevant question instead of answering mine. So the argument about Who is the fastest is futile... Again not my question, not my argument. Don't take my word for it, reread all my messages in this thread. So you might say, what is my point ? For the last 5 years, I am converting ADABAS databases to other vendor Databases for various customers. Good, so you should have enough first hand facts to present in support of your position and should not have to rely on papers on the web. Show it if you have something ... anything, don't be like SCO. There is various consultant Databases available on the WEB but for some of them you have to be a paying member. Consultant databases ? Who is talking about consultant databases ? If you stick to the point we might be able to settle as to why the failed conversions are IBM's fault. Once that's out of the way I won't mind discussing Consultant databases ( whatever they might be ). Conclusion : You are trying to defend DB2, which implies that you did not even understand that part of the conversation. I did NOT defend or attack anything or anyone, I only asked about the reasons for your assertion. Looks like YOU really have a comprehension problem. Hang in there... you can still be successful in the USA because you are trying. Now this part I sure do not understand like your earlier comment about my voting and some miracle you are expecting.

Re: Non-Standard Mainframe Language?
The point is that specific opcodes do not matter for generic operations and the reduced tedium is worth any loss of efficiency. For other operations where such hardware support is required, say atomic compare and swap, these can be coded in assembly for the OS code and an API can be made available for applications if needed. Even the compiler can have some mechanism for indicating specific needs and generate appropriate code. As for your comment about macro facility you have a valid point but the C preprocessor does what it's supposed to do and that's enough. The languages you mentioned, PL/X etc., have not been available to the rest of us though extensively used by IBM itself. In fact its use by IBM validates my point about a high level assembly language closely tied to the OS being generally better than assembly language tied to the CPU in addition to the OS.

Re: Non-Standard Mainframe Language?
Well, C on UNIX is really assembler - just one step removed from the bits and bytes of the underlying CPU. Its designers realized that there is not much benefit in writing CPU specific code to copy x bytes of memory to another location over the generic a = b kind of code. Same for other basic operation common to most CPUs - arithmetic, compare, branch etc. Going CPU specific and lot of tedius work one could get a few percent CPU savings but it wasn't considered to be worth it. And I tend to agree. On the other hand OS specific facilities ( macros, SVC ) were wrapped for easy use in standard library. Then again their standard library is NOT z/OS standard library, though you can try to map it. This also made their application and system programming domains a continuum rather than two isolated domains. A similar approach for MVS would have been great in my humble opinion but it developed on very different lines. On one side we have COBOL programmers who hardly know anything about the capabilities and strength of the underlying OS. Their domain is merely the generic computing functions ( arithmetic, compare etc. ) and middleware API ( CICS command level, DB2 SQL, IMS calls etc.). Just ask any COBOLer about coding a program with parallel tasks. This step is a lot easier for a UNIX programmer. On the other hand the real programmers talk in bits and bytes which does create a guru aura but isn't easy for the newcomers.
