Re: [U2] Rgarding ED editor
Hi Shanmukh, Do you really mean ED? The ED command in Unidata starts the underlying operating system editor. By default, this is vi on Linux and the MS-DOS editor on Windows. So, to answer your question, we need to know which system your are on. I have encountered many users who amend their VOC so that ED actually runs the AE editor which is part of Unidata itself.

Not odd at all. The language defines the relational operators as performing a numeric comparison if both items being compared are numbers or can be treated as numbers.

Re: [U2] What is true
on universe (not sure of unidata), you can use FILEINFO() to see if something is a file variable: x= crt fileinfo(x,0) returns 0. Would return 1 for an open file. This originated in Prime Information and is available on UniVerse, UniData, PI/open, QM, and probably a few others.

Re: [U2] What is true
Hi, About the true/false thing, I always use 0 and 1 but I was chastised about that by a colleague recently, that it might not be completely cross-platform, and now I stutter on it every time I do that, wondering if I'm not really following a best practice I seem to recall this same topic being discussed a year or two back, perhaps in a different group. In the multivalue world, the language definition says that anything that returns true/false returns 1 for true, 0 for false. Anything that interprets a value as true/false treats zero and a null string as false, everything else as true. This definition holds for all multivalue products but not necessarily in other languages. Any new multivalue product that breaks this definition is probably doomed to failure because migration of existing applications would become a nightmare task. In our type variant world where we have no such thing as a Boolean data type, it is very easy to write statements such as INVOICED = 1 Is INVOICED a Boolean variable, perhaps telling us in this case that an invoice has been raised? Or, is it a state flag with multiple values for which this might be indicating a type of invoice that has been sent? There is no way for the reader to tell. At risk of starting a whole new discussion on programming style (and I start form the viewpoint that there are many acceptable styles, it is more important to be consistent), this is probably best resolved by use of tokens. I have for many years held an interesting opinion that a program should never have any hard coded numeric values except perhaps zero, not that I adhere rigidly to my own opinion. The above line becomes something like INVOICED = TRUE or INVOICED = INV.PDF Now, all is clear(er) to the reader. Prime Information introduced @FALSE and @TRUE as symbolic constants (0 and 1 respectively) to avoid the need for our own equated tokens and several other multivalue products have followed this convention. Of course, nothing is ever completely black and white. As multivalue Basic has developed, internal data types have gone beyond simply numbers and strings. If I write IF FVAR THEN ... where FVAR is a file variable, what do I expect this to do? The language definition does not tell us but most multivalue products would give us a data type error of some sort because there is no rule for transforming a file variable to a Boolean value.

From Martin's response, I'm guessing not for QM, either. In QM, the @1, @2, etc variables are simply local variables within the I-type expression. This gives us the useful advantage of being able to nest compound I-type but does, as you suggest, prevent their use to retain values across uses of the I-type.

Re: [U2] Running total
Hi,
As far as I know, the only way to do this in U2 is to use either a common
variable or one of the @USERn variables in a subroutine to
accumulate the result. Handling multi-values is not hard (as below). Getting
this to work for breakpoint lines is a bit more
awkward.
For example, using UniVerse's demonstration sales database (INITIALIZE.DEMO), I
can create an I-type named ACCUM that reads
I
subr('ACCUMULATE', ITEM.TOTAL)
MD2
Cumulative
8R
M
BOUGHT
and a program catalogued as ACCUMULATE
function accumulate(item)
common /total/tot
if @ni = 1 then tot = 0
x = ''
n = dcount(item, @vm)
for i = 1 to n
tot += item1,i
x1,i = tot
next i
return (x)
end
I can then do
LIST ORDERS PROD.NO SELL QTY ITEM.TOTAL ACCUM
@ID.. Product No Sell. Qty. Item Total Cumulative
10002 605 $40.00 1 $40.00 40.00
501 $5.00 1 $5.00 45.00
502 $5.00 1 $5.00 50.00
504 $5.00 1 $5.00 55.00
10006 112 $6.00 3 $18.00 73.00

Re: [U2] History of Prime Information
I can add that I think VMark rewrote Prime Information in C which really boosted the performance. I think they called it Prime Info or something like that. I'm not sure about this. As far as I know, once VMark took ownership of Prime Information, they gently retired it. Are you thinking of PI/open? If so, I was one of the technical managers for its development. PI/open started life in Prime Australia where the intention was to write it using a macro assembler called K9. Shortly after they got started, Prime Australia was closed and development moved to the UK. I took a look at K9 and decided that it was the wrong way to go as it made assumptions about the underlying processor architecture that were not necessarily valid if we wanted portability without massive rewriting efforts. I made a decision that the core of PI/open would be written in C. This was highly contentious. I can recall a project meeting in which the VP of Engineering stated that my continued employment was dependent on this being successful. At the time, Prime's C compiler was not good and there was much doubt about whether it would produce good code. One of my team was tasked with finding a good C compiler. He took the interesting approach of constructing a very devious program that used all manner of C operations to construct and display the ubiquitous Hello World string. Comparison of the resulting object code from a variety of compilers showed that some were not that good whereas one of them evaluated the entire process within the compiler and just generated a print of the literal string. A few performance critical bits of PI/open were still written in assembler but I put a rule in place that there must be a C equivalent too. It is interesting to note that just a few weeks before first release the marketing guys decided to change the platform on which it would be launched. If we had gone the assembler route, this would have imposed a huge delay. With C, it took just a few changes to recompile everything. Phew! I still had a job.

Re: [U2] Unidata Index question
Hi Jeff, 1) If I have an index built for a given field FOO, and perform a query with like such as FOO LIKE 'ABC...' does it benefit from the index? Or is it only queries with equality conditions that benefit from the index (eg: FOO EQ 'ABC' )? An index can be used for a LIKE comparison with a literal element at the start but not if the ... is at the start. 2) If I have an index built with Empties=NO and then query with that indexed field =, how does it handle the query? Does it not use the index at all? Because the condition would be met by a null field and you have disabled indexing of null items, the index will not be used. Beware of queries like WITH FLD 4 when using NO.NULLS as again the condition is met by a null item, preventing use of an index, whereas WITH FLD 4 could use an index.

Re: [U2] Advantage of indirect call in BASIC
Hi, A direct call has to be looked up once in the catalogue system when it is first used. Subsequent calls will be fast because the link has been created. However, if the call is itself in a subroutine and that subroutine exits, it starts clean again on next call and hence may need to rebuild the link. I say may need to because there are various layers of caching that speed all this up. An indirect call starts out with a string variable. The first call will do the catalogue search, link the program, and replace the string with a variable that acts as a fast link to the subroutine. The link only needs to be rebuilt if the variable is overwritten or discarded. This means that putting the indirection variable in a common block that is only initialised once will do the catalogue search only once. Resetting the variable (local or common) before every call will require the search every time, though again caching may help. Long ago, I did some performance comparisons on UV when delivering an Internals course. I have lost the results but I seem to recall that it was well worth using links in common for subroutines that are called enormous numbers of times.

Re: [U2] BFORMAT
Hi, There's some wacky stuff it's doing with memory in that ED program, I can't figure out what they are trying to do Of course it was originally written in 1992 as a port of the PI/Open Editor I remember this being implemented from my days in PI/open development. It was all about performance when editing very large items. If the data was stored as a single dynamic array, processing is easy but becomes painfully slow with massive records. I recall comparing ED with another editor that did not break the data up in this way. When the data was over 100,000 lines long (I cannot remember what this huge item was), the performance difference was huge. Although processors are now a lot faster than when this was written over 20 years ago, the gains are still worth having.

Re: [U2] Virtualizing a Universe server of 100+ users
Hi, I saw a UNIVERSE job site recently have networked UV systems WITHOUT using UV/NET. They used the networking built into the OS (Windows or UNIX). Sounds good, right? Not until you realize that there was no record locking because the OS had no concept of a UNIVERSE record. It's worse than that. There is no group level locking which protects the pointers that link the internal structure of groups. Without group locks, the chances of corrupting a file are very high. Not just losing records but losing the structural integrity of the file.

Re: [U2] Virtualizing a Universe server of 100+ users
Hi again, Well for networked UV systems, you would only need group and record locking *if* the UV systems were trying to write to each others hashed files. Almost but there is still the possibility of the remote system reading a group for which the local system has a group write lock and is changing pointers. I have in the past spent many happy hours fixing UV files where a client had accessed the same file from two system using a Unix mounted drive to access the remote file.

They appear to be printing, report success back to Windows, but nothing actually emerges from the printer. This is well documented on the web. For situations where the application cannot do GDI, there are a few products out there that act as middleware to connect a text mode program to a GDI printer.

Re: [U2] Passing dimensioned arrays
Hi, The line is simply ignored as if it were not even there. If you make it bigger, then try to list past the end, the runtime blows up. If you make it smaller, you can still address the end cells normally. It's really as if the line isn't present. Don't ask me why it works that way, but hey. As I said in my previous posting, this is how the designers of Prime Information documented that it would work. Depending on the flavour of UniVerse you select, you either get Information style matrices with this behaviour or Pick style matrices that have different rules. Incidentally, because it is clear that some developers might actually want to be able to redimension matrices that were passed as arguments, we spent about five minutes adding a REDIM statement to QM yesterday that treats argument variables just like any others. I find it hard to believe that it would be difficult for UV to do the same if the demand is there.

Re: [U2] Array Types
Hi Jeff, The answer depends partly on whether you are using UniVerse or Unidata. In general, a dimensioned matrix will be faster because you can index directly to the required item, however, you have to trade this against the cost of doing MATREAD or some equivalent to populate it. Also inserting and deleting items is tough. A dynamic array requires the system to search for the desired element which clearly could take a long time if you want something at the far end. Inserting and deleting, however, is very quick. The UniVerse/Unidata difference is that UniVerse maintains a hint pointer that points to the last field that you extracted. Thus, if you walk linearly from one end to the other (in either direction) it can use the hint as a starting point and get the result very quickly. If you hop around all over the place, the advantage of the hint is lessened but usually still good. My understanding is that Unidata does not support field hints. The best thing is to try experiments with realistic data sizes and access it in the same way your application would.

Re: [U2] RESIZE - dynamic files
Hi, The various suggestions about setting the minimum modulus to reduce overflow are all very well but effectively you are turning a dynamic file into a static one, complete with all the continual maintenance work needed to keep the parameters in step with the data. In most cases, the only parameter that is worth tuning is the group size to try to pack things nicely. Even this is often fine left alone though getting it to match the underlying o/s page size is helpful. I missed the start of this thread but, unless you have a performance problem or are seriously short of space, my recommendation would be to leave the dynamic files to look after themselves. A file without overflow is not necessarily the best solution. Winding the split load down to 70% means that at least 30% of the file is dead space. The implication of this is that the file is larger and will take more disk reads to process sequentially from one end to the other.

I think the answer may lie in the splitting process. As I understand it, the first time a split occurs group 1 is split and its contents are split between new group 1 and new group 2. All the other groups effectively get 1 added to their number. The next split is group 3 (which was 2) into 3 and 4 and so forth. A pointer is kept to say where the next split will take place and also to help sort out how to adjust the algorithm to identify which group matches a given key. Based on this, if you started with 1000 groups, by the time you have split the 500th time you will have 1500 groups. The first 1000 will be relatively empty, the last 500 will probably be overflowed, but not terribly badly. By the time you get to the 1000th split, you will have 2000 groups and they will, one hopes, be quite reasonably spread with very little overflow. So I expect the average access times would drift up and down in a cycle. The cycle time would get longer as the file gets bigger but the worst time would be roughly the the same each cycle. Given the power of two introduced into the algorithm by the before/after the split thing, I wonder if there is such a need to start off with a prime?

Re: [U2] RESIZE - dynamic files
Hi Chris, The whole point of dynamic files is that you don't do RESIZE. The file will look after itself, automatically responding to variations in the volume of data. There are knobs to twiddle but in most cases they can safely be left at their defaults. A dynamic file will never perform as well as a perfectly tuned static file but they are a heck of a lot better than typical static files that haven't been reconfigured for ages.

Re: [U2] Regarding: use of I - Descriptor
Hi Satya, Although we deliver training to U2 clients in the UK, I suspect that you are in the US which makes our services irrelevant for you. The obvious place to go for U2 training is Rocket Software but I do not know what courses they offer in the US. If you are looking for some general multivalue training materials, most of the Teach Yourself QM course available from the downloads page of the openqm.com web site is applicable to U2 though there are some significant differences. There may be other self-study training packages available. Perhaps other readers of this mailing list will provide some details.

Re: [U2] Regarding: use of I - Descriptor
Hi Satya, These are really basic questions. You would be best to take a training course. An I-descriptor is a calculated value based on other dictionary items. Field 2 holds an expression that can include most of the things that you can do on the right hand side of an equals in an assignment statement in Basic. For example, you might have an I-descriptor named PROFIT with an expression of SELL - COST Once you have created the dictionary item, you can use it just like any real data field in a query processor command. By far the most important part of I-descriptors is the ability to use the TRANS() function to get data from other tables.

Re: [U2] matrix dimension
Hi, Multiple dimensions in DIM implies that all elements in each dimension would exist, around 25000 in your example. Using dynamic arrays, even as part of a dimensioned array is much more flexible as unused elements may not need to exist. And UV allows seven dimensional dynamic arrays - more than enough for most users!! Of course, indexing into a dimensioned array would be faster. Your request is close to something we were asked for in QM, arrays of arrays. Although technically easy we have not done it as the user requesting it withdrew the request. The hardest part is how to fit it into the language syntax.

Re: [U2] Turn a device and inode into file name
Hi, There is no trivial way to do this because a single inode may correspond to multiple file names if there are links. A useful trick if you run ACCOUNT.FILE.STATS from time to time is to look at the data file that it generates. This includes the inode numbers. Of course, a better solution is to write a little program to build a file that relates file names to inode numbers. You can then do queries against this. Or you could add a VOC entry that finds the inode number for each F-type entry and query against this.

I have some numbers from a benchmark tool, but, there are so many factors involved, I can't really tell you whether U2 performance is 30 times faster... Although I'm hoping this week I can get Universe installed and run through some jobs to see. The tool on RHEL 6 is telling me that on using the sync io engine, that random reads are 30 times faster, and, random writes are 60 times faster, which I find funny. BUT, I'm no expert on which io engine Universe uses (sync, libaio, posixaio, etc. etc.) In my case, I don't work for that big of a company, but, IBM was offering a 40% rebate on some of their solid stuff in October, and our AIX support was slated to end in April. That being said though, if you are the guy that has to research the hardware, I'll give you these pointers that I have learned painfully... If you are running on an x86 machine (intel-ish), keep in mind these points: 1) There are a couple of different types of solid state drives. -SATA, SAS attached to an actual disk controller (These are limited by the throughput on the disk controller, which they will quickly eclipse) -PCIe (PCI Express) that plug directly into the PCIe bus of the system (These are not limited by a disk controller and communicate almost directly with the CPU/RAM/bus) The PCIe are not bootable however, but, they bypass the latency of a traditional disk controller, and are even faster. They do come with the added complication of proprietary drivers, so if you don't get good support for this, things can get painful. 2) Be sure and buy enterpise SSD's. For example, an Intel 320 SSD is probably not an enterprise SSD. The quality of the firmware/drivers and flash memory is pretty key on these things, and the prices range from $200 all the way up to $4,000+ a piece. Basically, just do your homework on what the predicted life of the drive is. Don't always pay attention to warranty or hours. Its more about, How much data in GB can I write to this thing before it wears out. Also the cheap ones really fall short on random write performance which I think is important in a U2 database. 3) Make sure its in your budget. They are still at least double or triple the price of spindle disks (for the enterprise grade stuff). However, the performance is more than double/triple, so, the cost justifies itself. I think IBM has some SSD's offerings for their new POWER 7 AIX machines as well. Now for some more specific Vendor advice, as a result of some of my pain I have experienced the last month or so. If you go with one of the big boys for a RHEL (Linux) or Windows server, here is some useful info. IBM and HP (not sure about Dell) offers mainly two types of SSD's The traditional SATA ones http://www.redbooks.ibm.com/abstracts/tips0792.html The PCIe Ones http://www.redbooks.ibm.com/technotes/tips0729.pdf *Be careful about how you hook up the traditional SATA ones.* My so called Vendor was supposed to do all of this checking for me, but, they dropped the ball big time. IBM has a list of controllers that are compatible with certain machines. http://www-03.ibm.com/systems/info/x86servers/serverproven/compat/us/xseries/controllers/matrix.html So make sure that matches up. I'm sure HP, has a similar posting somewhere. THEN, make sure the controller can support SSD's. SSD's behave way differently than regular disks, so, IF you want to use a hardware RAID controller or something of the like, you must make sure it is intelligent enough to handle the SSD's. OR you can just hook it up to an HBA (Host bus adapter) with no actual intelligence, and then let the OS handle how it deals with the SSD's (i.e. software RAID, lvm, etc.) If you know Linux lvm, RAID, or Windows disk management, this might be the best approach for you. *Be wary of the vendor you buy the PCIe SSD's from* Like I said, IBM offered 40% off of these guys a month or two ago, but, their support people don't know a #$%^$## thing about them. The company that makes these things for HP, IBM, and I think Dell is called Fusion IO: They just went public on the stock market not too long ago. http://www.fusionio.com/platforms/iodrive/ HOWEVER, they have a non compete agreement with IBM, that states that any IBM branded card, they cannot support, EVEN though, they are the exact same stinking thing. So... if its in your budget to get these cards. Just buy it direct

Re: [U2] The math just doesn't work.
Hi Brett, The realisation for me here is that PRECISION has nothing to do with the precision of the calculation, it only effects display. Correct. All arithetic operations work at the precision of the underlying hardware. PRECISION applies when converting a floating point number to a character string.

Re: [U2] The math just doesn't work.
Hi Mecki, I actually wonder if this feature is flavour specific? Pick didn't use floating point arithmetic and IIRC the default precision used to be 4. PRECISION affects the number of decimal places in the result when converting a floating point value to a character string. All internal arithmetic operations are performed at the precision of the underlying hardware. Applying precision at each arithmetic operation would introduce cumulative rounding errors.

Re: [U2] uppercase
Hi Jeff, The difference is probably only one of performance. Using OCONV requires the conversion code to be decoded in order to work out what to do. Using UPCASE() can go straight off to do the real work without any additional decoding. I suspect not, but there may be some difference of interpretation if you have NLS installed.

Re: [U2] Universe : different time zone from AIX
Hi Marcos, Simply changing the timezone at the o/s level is probably not good enough. For full multi-timezone support you need to store times internally in a zone independent manner and convert them to the appropriate external timezone for each user. This is not a trivial task. It was also the motivation for the epoch dates development in QM a couple of years back but that doesn't help you much except to confirm that we know how tough it is. UV does have a SYSTEM(99) function to return the time as an epoch value but, as far as I am aware, does not have the rest of the functions needed to make this work properly.

Re: [U2] Multi char delimiter in DICT item
Hi David, Bob is right. Lets enhance the FIELD function to accept a string delimiter and not just a single character. A nice idea but it has to be a new function because FIELD() is defined as using only the first character of the supplied delimiter. Because an enhancement such as this is unlikely to appear in time to resolve the original poster's problem, it should be possible to work around the issue by replacing all of the multi-character delimiters with some single character that would never appear in the data and then using FIELD() with this as the delimiter. I cannot remember whether Unidata supports CHANGE() in I-types. For some strange reason UniVerse does not.

Re: [U2] Is this worth rewriting?
Hi Dave, In general, access to an element of a dimensioned array is fast so the frequent references to PARM(12) should not be a problem. On the other hand, even with the benefits of field level hints, repeated references to the same field/value may be improved by extracting the data into a temporary variable. Incidentally, and at the risk of starting a new war on style, this is a great example of why developers should use equate tokens with meaningful names rather than numbers for field references. As someone who has never seen this code before, I haven't got a clue what it does. Using names hopefully makes the code readable, it makes it easy to find all references to a particular item without having to dismiss all the other references to the same field in a different file, and it reduces errors from typos. Ignore me if you like. It's just a personal hate!!

Re: [U2] Is this worth rewriting?
Hi Dave, The reason I ask specifically of the repeated references is, during one of the sessions at U2UG-Denver, it was implied that each time you reference a specific location in a table, the OS basically has to start at the beginning of the table and 'find' its way to that location Whilst REMOVE is the quickest way to walk through a dynamic array, field extraction in UV uses a hint mechanism to keep track of the last field accessed. For example, if you have a huge dynamic array and extract field 640, yes, it will have to walk along from the start. If you next go to access field 650, it starts from the known position of field 640 so it will be much faster. This mechanism only works for fields, not values. Also, as far as I know, Unidata doesn't have this mechanism so it would need to start over each time. Dimensioned arrays are totally different. You can access X(1000) just as quickly as X(1) because it is little more than a reference to an indexed table of pointers.

Re: [U2] Questions abount Resize on Universe
Hi Marcos, With no options, it should be safe to stop the RESIZE as it copies the data to a new file which it renames to replace the original afterwards. This new file may be left behind (named resize) and can be deleted. With the USING parameter, beware that the data is first copied to the temporary file (as above) and then copied back. It is safe to abort the first phase but aborting the second phase will leave you with a corrupt file. With INPLACE, I suspect that the file will be unusable if you abort it.

Re: [U2] Does Reality Flavor have globally cataloged subroutines?
Hi George, If I do that, then I lose the features of the Reality Account correct? Or Do I change it, catalog the routine, then change it back? You could create an alternative named VOC entry that uses INFORMATION.FORMAT to save changing it back. However, it may not really be an issue. The Reality mode version of CATALOG behaves the same as the Information style one with no extra options (what Ideal/Information and PI/open call normal mode). By selecting the INFORMATION format you gain LOCAL and global modes. The problem is that those accounts were imported from a Reality system, and I wanted to use some of the subroutines that were written on another account imported from a Prime system. The mode of CATALOG has no effect on what you can call. It only determines how the cataloguing is done.

Re: [U2] fnuxi problem
Hi all, Thanks for the various suggestions. Research has shown that fnuxi sometimes hangs on the DATA.30 files but conversion of the directory representing the dynamic file appears to work ok. Because of the directory hierachy used by this site, some of the suggestions simply don't work but it looks like we can do it in two passses; one for the dynamic file (process all directories) and one for dictionaries and indices (process files beginning D_ or I_). It's messy but it looks hopeful. It's a great shame that fnuxi doesn't work better and even have a recursive option. It has cost about a day and a half of work to get something that looks like it might work. Brian's suggestion of using uvbackup and uvrestore was considered as a last resort. With the vast number of files on this system, this is likely to be painful process. Thanks again for the help.

[U2] fnuxi problem
Hi all,
I am on a UniVerse client site trying to move an application with a vast
number of dynamic files, some indexed, from UV 10.1.18 on a Sun Solaris box
to UV 10.3.6 on a Red Hat Linux Intel box.
The data files were moved with tar and byte order conversion was done using
find . -type f -exec fnuxi {} \;
This appeared to work but, on testing the application today, it now seems
that it skipped quite a few files along the way. Given that fnuxi is
supposed to ignore files that don't need conversion, I simply ran the
process again. It hung after converting a number of files, looping at 100%
cp.
In an attempt to make this restartable, I created a shell script with each
file as a separate fnuxi command. Again, this works for a while and then
hangs. At each hang, I note the failing file, remove everything down to that
point from the script and try again. The hangs are so often that this has
become unworkable (there are about 400,000 files in the list).
Repeating the fnuxi for a failing file sometimes fails again and sometimes
works ok. I have also seen it fail with a segmentation fault.
Some of the hangs are on the data files, some are on indices. I have even
used filepeek to walk through a failing file looking for ideas about why it
hangs.
So, has anyone experienced the same problem and, far more importantly, has
anyone got a fix or an alternative suggestion of how to move this system?
Thanks.

Hi Will, Are there are native implementations of a Pick system on Macs? As Henry and Allen have both said, our OpenQM product runs on Macs. We have installations ranging from MacBook Pro laptops right through to Mac Servers. Since your query is raised on the U2 list, it is fair to say that, of course, QM is not U2 however migration should be very easy if you want to go down this route. There is an evaluation version available. Probably any further discussion should be via the OpenQM Google group rather than here.

Now that you have raised the topic Tony, yes QM does have support for Procs (PQ, PQN and PQX style). Unless the application does anything particularly out of the ordinary, the changes made to QM over the last year or so to ease migration from Pick style systems should make this move fairly painless.

Re: [U2] FW: Running total from UniData dict
Hi Chuck, I take it QM does not support this use of the @n buffers, then? If I may change the subject slightly, how about nested compound I-descriptors? We have the @n variables but they are local to the specific I-type expression and hence don't persist from one evaluation to the next. We resolved the running total problem by adding a CUMULATIVE keyword that works like TOTAL, etc including sub-totals at breakpoints and so on. Yes, we support nested compound I-types to any reasonable depth. This is actually fairly easy once you make the @n variables local to the expression. Sort of related, we also fixed one of my real annoyances about U2 by allowing a TRANS() to retrieve something that is itself an I-type. And (perhaps further discussion should be on the OpenQM Google group).

Re: [U2] Universe Retrieve
Hi Henry, You can see the object code that is produced using VLIST and examine it for optimizations. The particular optimsiation that Barry is looking for would not show in the object code. For a truly constant I-type expression, the query procesor could evaluate it just once and store the result instead of doing it on every use. Although not common, such I-types do exist.

Re: [U2] Universe Retrieve
Hi Henry, I was under the impression that an EVAL calls the same compiler that an I-type does, and that any expression optimization would be done therein. As far as I know, EVAL does indeed call the same compiler. As I think you realise, the point is that an I-type expression such as 1: I 2: SPACE(3) (which I have seen used to get differing column spacings) will compile to a pcode sequence that produces a string of three spaces. This does not tell us how the query processor will then go on to use it. A normal I-type expression, whether from the dictionary or from use of EVAL, would be executed for each occurrence of it in the report, typically once per record. In the case of my spacing expression above, the query processor would actually only need to evaluate the expression once and then drop it into the report as a constant item. I think that this is what the original poster was asking about. I have no idea whether UV does this (QM does). Your experiment seems to tell us. Here are some empirical results using UniVerse 10.2.7: TIMEIT 50 COUNT VOC WITH F1 = 'V' COUNT VOC WITH F1 = 'V' Elapsed 1.3006 TIMEIT 50 COUNT VOC WITH F1 = EVAL 'V' COUNT VOC WITH F1 = EVAL 'V' Elapsed 5.135 This suggests that the query processor does not detect that the result of the evaluation is a constant and optimize its execution. No, I think that this is actually showing the opposite. The query was considerably faster where your test was a simple literal WITH F1 = 'V' whereas the EVAL expression added a further four seconds to your query. If the query processor detected that EVAL 'V' was a constant and optimised it I would expect both queries to take the same time. It does look as though it is evaluating the expression for every record.

Hi Marco, The dynamic array test took 30 minutes. I compiled the same program on jBASE 4.1 on the same laptop and it completed in 0 seconds!

Re: [U2] General guidelines on indexing
Hi all,
I don't agree. Disk access is inherently slower than RAM access.
I think that this discussion started for Unidata and then got UniVerse
involved too but it might have been the other way around. Sadly, there is no
internals training material for Unidata so we have to guess what goes on.
Different multivalue products approach string management in varying ways. In
UniVerse, strings are stored as contiguous memory. If I write a statement
such as
X-1 = 'ABC'
this run machine has to work out how big the new string will be, allocate
memory, copy the old value of X to the new area appending ABC to it, and
then release the original memory used by X.
As you append successive fields, the string to be moved gets longer and
longer. We tend to think of computers as being blindingly fast but copying a
big string is still a slow process. If I have a string that starts empty and
I add a million fields, each of 3 bytes plus the delimiter, I will end up
copying a total of 1,999,998,000,000 bytes - hardly an insignificant task.
From my own experiments some time ago, I believe that Unidata also uses
contiguous strings but I have no direct proof of this. The alternative
(adopted by our QM product, by PI/open, Information and perhaps others) is
to use chunked strings where a string is stored as a series of chunks. In
this model, appending a field requires only addition of a new chunk or, for
better performance, replacement of the final chunk.
Of course, the performance gain of chunked strings in this example may be
offset by their decreased performance for things like substring extraction
which is now more complex than a simple indexing operation.
By way of a simple expample, I just tried the following program...
s = ''
z = str('*', 1000)
t1 = time()
for i = 1 to 10
s-1 = z
next i
t2 = time()
crt t2 - t1
This took six seconds on QM but 32 minutes on UniVerse. I do not have a
Unidata system available at the moment to try. To be fair, I am sure that I
could construct an example that reversed the performance difference.
Writing to a sequential file is somewhat similar to the chunked string model
as it buffers data until it has a good sized chunk and then writes it out,
continuing with an empty buffer.

Re: [U2] General guidelines on indexing
Hi again Ed, SELECT file WITH PRINT.DATE GT 01/04/2008 AND WITH ADDR LIKE 'A'0X This query can be resolved with an index. Also, the optimiser will shuffle the clauses to make best use of indices. Unidata had query optimisation before UniVerse but I believe that essentially the same algorithms were ported across for UV 10. I have played games trying to defeat the UV optimiser and I have to say the I am very impressed by it. SELECT file WITH PRINT.DATE GT 01/04/2008 OR WITH ADDR LIKE 'A'0X This cannot be resolved with an index because the second condition cannot be determined without reading all the records. Also, my indexes look to be out of date, as the non-indexed and indexed selects return different numbers. That is worrying since the index system is supposed to guarantee consistency between the data file and the index. The only time that they should ever be able to get out of step is after a system failure or killing a process in the middle of a write.

Re: [U2] DIR-type files
Hi Dan, At ECL, if you type ED BP ../../etc/host You get the /etc/host file in ED! This works in Unidata because it simply forms the operating system level name by merging the file name and record id. UniVerse has name translation rules for restricted characters and your example would end up as ?..?\..?\etc?\host and, if using type 1 files rather than type 19, would then get further transformation into a two level directory structure. Both methods have their advantages and disadvantages.

Re: [U2] Any limitation in UniVerse decimal places
Hi, In short, problem can be described as it is caused by? the fact that on certain condition represented by combination of large number of invoices and over 9 digits totals Universe engine creates a small fractional addition to total number. Not quite right. The problem here is that, just as there are numbers that cannot be represented accurately in decimal such as 1/3, there are numbers that cannot be represented accurately in the binary notiation used by the computer. As an easy example, the number 0.2 cannot be represented accurately and ends up as something like 0.20001 as a close approximation. Because IEEE floating point has a limited number of bits to store the matissa part of the value, the whole thing scales with bigger numbers. Essentially, a number cannot have lots of significant figures, wherever they may be in relation to the decimal point. If you add up a large number of figures with these rounding errors they may accumulate to something significant. Even worse, if you decide to do decimal scaling with a simple multiply instead of an MD conversion code, the inaccuracies get scaled too. This problem is not unique to UniVerse. It is a well known probelm of floating point numbers in computer systems. The usual fix in the multivalue world is to scale numbers (dollars to cents, for example) so that all our numbers are integers. UV also provides a set of character string arithmetic functions if you really want to get clever.

Re: [U2] Select Field Comparisons
Hi Ron, This is the issue of non-reversible conversions. When you do a query such as SELECT BILLS WITH DATE = 12 Jan 09 the query processor converts the 12 Jan 09 to its internal form and does all comparisons on this. Exactly the same happens for any other field with a conversion code - the comparisons use internal form data. Your query: SELECT BILLS WITH QUARTER = 1 won't work because the value 1 cannot be converted to an internal date. So, queries of this form only work with reversible conversions. Using an I-type to do the conversion as part of the evaluated expression instead of as a conversion code in dictionary field 3 gets around this issue.

Hi Allen, If I know in advance that I'm adding a large number of records to a file, is there any way to force the file to grow in advance? You could do this with the MINIMUM.MODULUS parameter but the whole point of dynamic files is that they do their own tuning. Although a dynamic file is unlikely to be as good as a perfectly tuned static file, it will be a lot better than a typical static file that has been left alone for a long while. Another important point is that a split affects only one (or arguably two) groups unlike resizing a static file from modulo N to modulo N+1 which would affect every group. My real point here is that it is usually best to let a dynamic file look after itself.

Use of WHILE/UNTIL is sometimes easier to read. Conversely, some exit conditions can only be done using EXIT if they are, for example, in some deeper conditional construct. First I thought that the DO/WHILE would activate as soon as the condition occurred and drop out of a loop, but that is not the case, the condition has to be active AND control has to be back at the WHILE statement. Correct. The test is carried out at the point where you write it. A single loop can contain many WHILE/UNIT conditions scattered through it but uncontrolled use of this can make programs difficult to read.
