Re: [U2] I'm in an Array quandry, any suggestions...
I think one of the the things that we are overlooking is the underlying philosophy that machine cycles are cheap, and anything that cuts development or modification time is a Good Thing. You and I may not agree with that philosophy (having been victimized by code that took the idea to it's illogical conclusion), but keeping track of how many elements you need in a dimensioned array is one of the icky programmer type things that, historically, the music majors passing themselves off as Pick programmers were loath to do. But in the Real World, these kind of things usually (note the disclaimer) do not make much difference.

So if you're accessing fields in random order (as a lot of my code does) you gain nothing. No it does work even when you access the dynamic array in random order. It then provides an alternative starting point for the search to use instead of character 1. I'm not sure this is accurate. This would imply that not only would the run-time engine have to maintain a pointer to the last cell referenced, but also it would have to maintain a register telling it the cell number of this cell (not just its offset). So it needs two variables. I've never heard that it actually uses two variables to accomplish this. Perhaps someone in the internals could answer that question. So again, it would need one variable to tell it the offset (example: my last reference ended at character 96 of the string ... or position 2345 of the frame, or something of that sort); AND another variable to tell it the cell number (example: my last reference was to cell number 4). Otherwise, random access into a dynamic array would not be improved by the method talked about in this thread. Will Johnson --- Well it already needs both variables in the 'sequential' access too !

Re: [U2] Performance tuning UniVerse on Windows Server 2003
We run our UniVerse application on HP-UX, but we use a number of sql servers running on X86 type hardware. Our standard setup for a database server (Micro$oft SQL for us) calls for a dual processor machine with at least a gig of memory depending upon the size and number of users. We've found that disk usage makes a big difference (no suprise there). A mirrored set of disks should be setup for the system or C:\ drive. Another set of mirrored disks or a drive array should be used for the actual data files themselves. I've also found that using a single drive running by itself as a temp file system helps. On SQL server we put the swap file, tmp files and the tempdb on this drive. This leaves us with three volumes doing different things (program files, data and temp space). Resist the any urge you may have to configure one big disk and put everything there. Hope this helps. --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

RE: [U2] Performance tuning UniVerse on Windows Server 2003
If the server is running hyper threading then turn it off. That would be turn off the hyper threading, not the server. It can make a noticeable difference in performance.

RE: [U2] Performance tuning UniVerse on Windows Server 2003 {Unclassified}
Paul, We run UV on Win2K3, and have done for a couple of years, now. We handle 220 users very adequately on a dual-Xeon 2.8GHZ, 3GB system (from IBM, as it happens) Don's advice is all good! And if you're using transaction logging, the logs should go on a volume that is not the same as the main data volume. This is both for performance and safety - otherwise a single loss of a volume would wipe out data logs = no recovery! If you're running a really large or high-volume site, you may also wish to consider putting indexes on a separate volume to the main data. So, ideally you want at least three, preferably four separate disk volumes [logs could share with swap temp] All volumes should be mirrored / RAIDed for redundancy. Don't use software RAID. If you're using a SAN (we use EMC) you need two local volumes, one for C: and the other for (swap temp) and one or more SAN volumes. Remember that Xeons don't scale well past 4GB RAM, you will need Opteron's / Xeon-64's and Windows Server 64-bit edition for that.

I'm a great believer in INCLUDEs, but only after an extreme amount of thought will I put significant logic in them. If processing is necessary it should nearly always be done in the main program, or if needed in more than one place then in an external subroutine that you CALL. You chances of stuffing up a program that INCLUDEs logic by a small change to that logic are much higher than if you CALL it as an external routine. Immediately you eliminate the risk of someone introducing a new local variable into either your main line or the INLCUDE and finding that it collides with something else which was also supposed to be local.

Re: [U2] Include Vs Call - Software Maintenance
Bill, I need a UniBasic program that uses a lot of code from another program. I am inclined to move all of the common code out to an include file. If you do decide to use an include file, have a look at compile time directives. These allow block of code to be included or excluded by the compiler (think dynamic includes not runtime branching). I use these a lot when I need a block of common source to act slightly differently in multiple programs (I often use this so source from UV and UD can be held in one file and then a toplevel include sets C_CROSS_BUILD_UNIVERSE or C_CROSS_BUILD_UNIDATA so that platform specific code gets compiled in). This might let you have common code and then if you need to make small changes for a specific program you could do so. eg: MAINPROG1: $DEFINE MAINPROG1 INCLUDE INCLUDEFILE MAINPROG2: $DEFINE MAINPROG2 INCLUDE INCLUDEFILE INCLUDEFILE: blah blah common code $IFDEF MAINPROG1 THIS CODE WILL ONLY BE COMPILED INTO PROGRAMS WHERE MAINPROG1 IS DEFINED $ELSIF THIS CODE WILL ONLY BE COMPILED INTO PROGRAMS WHERE MAINPROG1 IS NOT DEFINED $ENDIF regards, Craig --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

Key to this discussion is revision control. Not being contrained by SOX, and having a single programmer here, consider the baseline...

PROGRAM.ONE.R8 ^ INCLUDE.FILE.R4 ^ PROGRAM.TWO.R11 INCLUDE.FILE.R3 If there is time to do maintenance on PROGRAM.TWO, it then becomes...

RE: [U2] Include Vs Call - Software Maintenance
In either case, you only want to externalize that code which performs a specific task or function. Just because two programs do something the say way doesn't make it a good candidate for being an include record or an external subroutine. As to which method would be better, the choice would be what kind of maintenance requirement you want to deal with. If you take a function and make it an external subroutine, you can then make modifications to the function without having to recompile all the programs that use it. If you make a change to an include file, though, you'll have to recompile all programs that use it. A rule of thumb that I like to use is includes are for things like common blocks of variable definitions, like open file handles, equates, and common variables that don't change. If there is any processing that is to be done, that would go into subroutines. Another thing to remember is that with included code blocks, paragraph labels and variable names are shared while subroutines they independent and can be reused, provided they are not part of a common block. It is a bit of a hard lesson to find out you've already used a variable name in your include block and reused it in your main code file for different uses.

RE: [U2] UV PERFORM 'SELECT filename ...' in I-Type {Unclassified}
Mike,
You say there is no select list active - but you are performing a LIST
statement, isn't that an implied active select list.
You shouldn't do anything in an i-type that could affect selectlist 0
(or use it up), and shelling out to perform a select would be very
in-efficient (one perform/execute for every record in the file you're
listing).
Using the basic SELECT in the u-type is probably your best option - but
without knowing what you're trying to achieve it's difficult to suggest
a better alternative.

I think you just have to be *VERY* careful about using any form of PERFORM/EXECUTE inside an I-type/virtual field. First there are performance issues to think about, second, if the thing you EXECUTE either generates or consumes select lists then you need to be awful careful to make sure you don't generate some unwanted side effects. I accept that sometimes there is really little option but to implement something like this, but I'd certainly look hard at all the alternatives I could before I sat down and cut code. For example, on UniData, I'd far rather create a secondary index on filename and do some READFWDs than either the internal or external SELECTs you describe, is there a UniVerse equivalent?

I think you will find this article interesting http://www.joelonsoftware.com/articles/Wrong.html Ross Ferris Stamina Software Visage - an Evolution in Software Development Interesting points on making wrong code stick out. I've met a lot of coders who are sticklers for indent formatting, yet they mix coding conventions under the same syntax use. Debugging a huge IF ELSE structure can be a major nightmare if the coder indents properly, but does not follow IF condition THEN result END conventions for every logic block. I don't know how many times I've looked at an old piece of code and seen: IF A 100 THEN IF B = 56 THEN GOSUB 100 IF U 90 THEN IF Y 10 THEN IF R = 1 THEN CRT 1 END ELSE GOSUB 100 END ELSE RETURN TO 500 END First of all, I'd never structure something that complicated in a single nested IF block. Secondly, END will happily kill any Pick app, if it doesn't have a matching IF THEN statement. The compiler won't complain. Some flavors are more strict than original Pick and do not use END as a program terminator. That is a problem that should have been changed eons ago. I've had to print out an entire page of code and use a pen to write matching IF/END symbols to help determine which specific line of a 20-30 line IF blob is killing the app mid-flow. I usually end up rewriting it with a combination of CASE blocks and multiple condition IF blocks. CASE blocks are the best for huge logic selections or parametric settings. You can't muck up the convention and it takes up a lot less space. Less lines means you can more easily spot bad logic code. Anyway, back to the original topic. I've used includes and subroutines cooperatively. Your subroutine can be parameter driven based on variables in the global include. Instead of passing values via the subroutine call, use global directives to tell a global sub how it should function. This is OOP in a _very_ primitive fashion. Such code can be modularized even further by splitting the parent sub into component subs that handle specific logic for each situation. Down the road, you can analyze and update the atomic components of the whole package without breaking every part of the system. You can also add new features without worry of backwards compatability. There is a line between atomic building blocks and a code tree that expands past your ability to comprehend it. I keep my modularization to 3 or 4 levels. If you need more than that, then reconsider the design or see if the new memory implants are available at your local doctor's office. !FILEIOPARAMS : FILE IO GLOBAL DEFAULT PARAMETERS OPEN.FILE.OPENMETHOD=PICK OPEN.FILE.FILENAME= OPEN.FILE.LOCKS=0 OPEN.FILE.ERROR=0 OPEN.FILE.ERRORMSG1 = CAN NOT OPEN FILE OPEN.FILE.ERRORMSG2 = FILE IS LOCKED !PROGRAM MYAPP INCLUDE FILEIOPARAMS OPEN.FILE.OPEN.METHOD = LOCAL OPEN.FILE.FILENAME = /tmpfiles/mytempfile.txt OPEN.FILE.LOCKS = 1 OPEN.FILE.POINTERNAME = MYAPP.FILE CALL OPENFILE IF OPEN.FILE.ERROR 0 THEN CRT OPEN ERROR: :OPEN.FILE.ERRORMSGOPEN.FILE.ERROR END EOF = 0 SELECT MYAPP.FILE LOOP UNTIL EOF = 1 DO READNEXT ID ELSE EOF = 1 CRT ID IF EOF = 1 THEN EXIT REPEAT STOP SUBROUTINE OPENFILE INCLUDE FILEIOPARAMS BEGIN CASE CASE OPEN.FILE.OPENMETHOD = LOCAL; SUB.NAME = OPEN.LOCAL CASE OPEN.FILE.OPENMETHOD = PICK; SUB.NAME = OPEN.PICK CASE OPEN.FILE.OPENMETHOD = HTTP; SUB.NAME = OPEN.HTTP.URL END CASE CALL @SUB.NAME RETURN SUBROUTINE READ.LOCAL INCLUDE FILEIOPARAMS OPEN OPEN.FILE.FILENAME TO OPEN.FILE.POINTERNAME ELSE OPEN.FILE.ERROR = 1 END RETURN I don't know if the variable file pointer assignment will work on all flavors or not. It does work under D3. Instead of using OPEN.FILE.POINTERNAME as the file handle, OPEN assigns that variable's value of MYAPP.FILE as the handle.

Immediately you eliminate the risk of someone introducing a new local variable into either your main line or the INLCUDE and finding that it collides with something else which was also supposed to be local. Did I mention that I always make sure that ALL the local variables in an included file have a unique prefix so that no two include files can have the same variables (except when passing data between them). eg: CROSS.SMTP.ENGINE: * ALL local variables start with SMTP
RE: [U2] UV PERFORM 'SELECT filename ...' in I-Type {Unclass ified}
Mike,
Doing a querying, within a query in RetrieVe, isn't recommended. That is, if
you I-type is doing a query, then that probably part of the problem. But it
works in the testbed, then perhaps the differences are with that
environment?
However, is your testbed account set to INFORMATION flavour too? As the
PERFORM and EXECUTE commands can work different depending on the account
flavour, syntax and/or $OPTIONs used.
Regards,
David

Subject: [U2] UV PERFORM 'SELECT filename ...' in I-Type {Unclassified}
Folks,
We have had a puzzling situation where a particular subprogram works
differently when run from a test-harness from TCL, to when it is run as an
I-Type subroutine.
The sub-routine concerned is about three layers deep in the execution
sequence:-
Test-Harness does CALL A(parameters), A does CALL
PROBLEM(parameters)
I-Type says SUBR(X,parameters), and X does CALL A(parameters), A does
CALL PROBLEM(parameters)
When you LIST file name I-Type name the I-Type returns 'wrong' answers
The programmer concerned eventually worked out that the problem was that,
from the I-Type, a PERFORM 'SELECT filename with-condition' ALWAYS
returned no records, whereas the same select works correctly from the test
harness. No, the were no select lists active at the time!
The solution was to change the PERFORM 'SELECT filename with-condition'
to a Basic SELECT filename and weed out the unwanted records in an
internal loop.
It may well be that it has always been this way, the I-Type is new. UV 10.0,
INformation flavour, Windows 2K3
Ideas, anyone?
Thanks
Mike
