Loop performance
Hello all
I have a loop which is coded as below ..
LOOP AT ij_cawn
WHERE atinn = j_3apghd-j_3abzd1.
EXIT.
ENDLOOP.
When analysis was done using ST12, this was shown to take huge time. I would like to modify this code as
Read tavel ij_cawn with key atinn = j_3apghd-j_3abzd1.
Binary search is not possible as the table is not sorted . Also I cannot sort it due to some other logic.
Could you please give me your valuable sggestions in thsi ..
Regards
Sudha
Hi,
make a copy of this internal table in other internal table.
sort that internal table. use Binary Search.
It can help you,

LOOP inside loop -performance issue.
hi ppl,
I want to put the select query mentioned below outside the loop to resolve performance issue. The 'for all entries' does not support aggregate functions like 'sum' and 'group by'. plz have a look at my approach and suggest some changes.
the code:
LOOP AT T_UNITS.
V_TABIX = SY-TABIX.
CONCATENATE TEXT-S01 T_UNITS-UNIT INTO VL_TEXT SEPARATED BY ' '.
CALL FUNCTION 'SAPGUI_PROGRESS_INDICATOR'
EXPORTING
PERCENTAGE = 0
TEXT = VL_TEXT.
get GLPCA postings
SELECT AWTYP AWORG RACCT REFDOCNR SUM( HSL ) FROM GLPCA "1062
INTO TABLE T_GLPCA
WHERE RPRCTR = T_UNITS-UNIT
AND RACCT IN S_HKONT
AND KOKRS = V_KOKRS
AND RYEAR = P_GJAHR
AND POPER <= P_MONAT
GROUP BY AWTYP AWORG RACCT REFDOCNR.
lopp at t_glpca.
endloop.
endloop.
my approach:
all this put outside the loop 'loop at t_units'.
SELECT rprctr AWTYP AWORG RACCT REFDOCNR HSL FROM GLPCA "1062
INTO TABLE T_GLPCA
For all entries in t_units
WHERE RPRCTR = T_UNITS-UNIT
AND RACCT IN S_HKONT
AND KOKRS = V_KOKRS
AND RYEAR = P_GJAHR
AND POPER <= P_MONAT.
loop at t_glpca.
v_tabix = sy-tabix.
select sum( hsl ) from glpca into t_glpca-hsl.
modify t_glpca index v_tabix.
endloop.
The select query 'select sum( hsl ) from glpca into t_glpca-hsl' is consuming lot of time.
thanks in advance
Archanahi ,
u can use sum function while displaying also .
u have selected some values into itab na .aftyer that use the below code.
loop at itab.
at end of <fielname>.
sum.
write:/ itab-<fieldname>.
endat.
like this also u can some .so u can use for all entries in select statement .
hopw it's usefull for u .
or use
on change of <fielname>
endon.
instead of at endof.
EXAMPLE CODE
SELECT *
FROM sflight
INTO TABLE sflight_tab.
LOOP AT sflight_tab INTO sflight_wa.
AT NEW connid.
WRITE: / sflight_wa-carrid,
sflight_wa-connid.
ULINE.
ENDAT.
WRITE: / sflight_wa-fldate,
sflight_wa-seatsocc.
AT END OF connid.
SUM.
ULINE.
WRITE: / 'Sum',
sflight_wa-seatsocc UNDER sflight_wa-seatsocc.
SKIP.
ENDAT. -
Performance issues using control references in Analog control loop?
My main vi of a tensile tester control application calls a number of sub-vi's, including a analog control loop which controls the test. The control loop must update some boolean and digital indicators and respond to user input on the front panel of the main vi during a test.
To simplify my main vi, I moved the control loop code into a sub-vi, and used control references to access the controls and indicators on the front panel. However, this has dramatically affected my loop performance, and the loop can no longer keep up with the acquisition speed.
Do control references always cause such a slowdown? Is there anything that I can do besides moving the code back into the main vi?
Thank You,
David CreechI have had the same problem. I have discovered other funny things about references also; some kind of memory management (or mismamagement?) is taking place behind the scenes.
Regardless, you can often do away with the references by passing the initial state of a control or indicator into the subvi, changing it inside, and passing the altered state back to the caller. Once back in the caller you update the front panel control or indicator by using a local variable.
One thing to watch out for if using this scenario is the dreaded race condition; this can be avoided using a state machine. Check out
http://www.advmeas.com/goodies/statemachine.html
for a good example. It is a shame that references behave in this way; it limits thier usefulness.
Perhaps someo
ne else will point out a way to utilize them more sucessfully? -
Performance tuning the loop statement
Hi,
I have the following requirement.
I have an internal table IT_TEST1 which has values
Column1
A
B
C
D
consider a second internal table IT_TEST2. It'll have values like as follows:..I need to know which are the entries in column1 that have more than one entry in column 2 without looping through this internal table..Kindly suggest..
Column1 column2
A VAL1
B VAL1
B VAL2
C VAL1
C VAL2
D VAL1
D VAL2
D VAL3
This has caused very big performance issue for it isHi,
I have faced a similar problem and the following strategy has saved a lot of processing time
the following code may serve your pupose
if you are using IT_TEST2 for further processing please use IT_TEST3
otherwise use IT_TEST2 instead of IT_TEST3 in the code below......'
*************************CODE SAMPLE************************************
data : IT_TEST3 like IT_TEST2. "declare internal table same as IT_TEST2
IT_TEST3[] = IT_TEST2[].
"Pass contents if IT_TEST2 is used for further processing
Sort IT_TEST1 by column1 . "Sort
Sort IT_TEST3 by column1 . "Sort
loop at IT_TEST1.
read table IT_TEST3
with key column1 = IT_TEST1-column1.
if sy-subrc = 0.
describle table IT_TEST3 lines n.
if lines > 1.
"Multiple entries
else.
"Single entry
endif.
endif.
"Perform all operations on IT_TEST3
DELETE IT_TEST3 WHERE column1 = IT_TEST1-column1.
"Delete the entry in IT_TEST3 already processed with the key of IT_TEST1
"Next time you do the read entries for the previous and all predecessor loops
will not be there'
"As you go down the loop performance increases

SE30, Performance, nested loop
Hi,
I looked at SE30 and found something verny usefull for my actual report.
The nested reports and how to do it better.
In the Documentation is written:
The above parallel cursor algorithm assumes that ITAB2 contains only
entries also contained in ITAB1.
If this assumption does not hold, the parallel cursor algorithm
gets slightly more complicated, but its performance characteristics
remain the same.
I would like to know the more complicated way, because I compare two tables which contain different entries.
Would anybody be so nice and help me?Check:

Need to Improve Performance on a Spatial Boundary Crossing Calculator
I am attempting to compare a series of geometries to calculate a number of statistics where they overlap. Essentially I have a table of 50,000 lines and another table of 1000 circles. I need to determine which lines overlap each circle, and for each intersection, I need to determine how much time and distance each line spends in each circle.
I have a PL/SQL program that performs this operation now and it works. The problem is that it takes far too long.
Here is a summary of how the job runs:
1) For each LINE, determine which CIRCLES it overlaps with
2) Each each LINE/CIRCLE pair, determine the intersection points
3) Insert the intersection points in a temporary table
4) Once you have all the points, pair them up as Entry/Exit points for each circle
5) Calculate duration (time) and distance between entry and exit points
6) Return to step 1 for next LINE
There are multiple loops here:
1-6 is the outer loop performed once for each of the 50,000 lines.
2-3 is performed once for each line/circle pair (probable avg of 5 circles per line)
4-5 is performed once again for each line/circle pair
Even if the process only takes a couple of seconds per LINE, we are still taking more than 24 hours to process, which is not acceptable.
This original process was written with 9i, and I am now running 10gR2, so I know there are new features that should help. For starters, I think I can use SDO_JOIN in place of the original outer loop to generate a complete list of geometry interactions in one query. Of course, I am still concerned about how long that might take.
Even more troubling is, if that works, I still don't see how to improve the rest of the calculations. Any suggestions would be appreciated.No, I don't mind providing it.

Hi Guys
I have some code that (currently) uses a while loop to periodically open a file and read from it (in its simplest form....and...the details are not germaine to this post)
The requirements have now tightened and the loop (While or Timed??) must read the file once every two minutes based on the computer clock (accuracy is not too important, certainly not milliseconds)
e.g. time is 11:35.... read file
time is 11:36.. ..do nothing
time is 11:37.....read file
time is 11:38.....do nothing
etc. etc.
In simpler terms (if thats possible)....have the loop perform the code inside it every two minutes with the time sequence coming from the pc clock.
I've looked at timed loops (but never used them) and they seem a possibility
So, could somebody show me an example of the best way to do this.
Thanks for your assistance and best regards
Ray
Solved!
Go to Solution.Hello Ravens Fan
I have had an attempt (unsuccessfully) at your suggestion, but not much luck I'm afraid.
I'm kicking myself because I should know how to do this.
I have attached my attempt. Would you please take a look at it and see where I'm missing the next ingredient.
Kind regards
Ray

Actual time recording (computer performance problem?)
I'm a beginner.
I'm recording the output file in every second, but the time of output file is different from the actual time.
I'm wondering if this is due to the computer performance (450MHz, 128MB) or if vi program can be implemented. I attached the file I use. The problem comes up when I use a vi with 50 channel outputs, but doesn't come up if I reduce the channels to around 20.
Thank you.

LODS_MFC2.vi 460 KBIt sounds like you are certainly running into timing issues. I see that in your VI, you use AI Sample Channel to acquire data from a single channel everytime the loop iterates. This is not the best means to go about doing such. The reason being that each time the VI is called, it has to setup the operation, then perform the read, and then clear the operation. What you should be doing is setting up the operationg outside the loop, perform only reads in the while loop, and then clear the task after you are complete. LabVIEW gets shipped with several examples that behave just this way, you should look in the example finder for these.
Additionallly, if you read the help on AI Sample Channel.vi, it states it does a single, untimed measurement of a channel. Since
you posted with the title "actual time recording", I feel that timing might be of importance to you.
You never did mention what version of LabVIEW you have, or the hardware and drivers you are using, so I am leaving this post rather general. If you have some more questions after reading through this post and looking through some of the examples, post back to this discussion with more information, and I will try and help you out further.
Sincerely,

A few days ago, we did a live web presentation and Q&A session about optimizing for performance for Adobe Premiere Pro and After Effects. Here is a blog post that gives a link to the recording and links to supporting materials:
"optimizing for performance: Adobe Premiere Pro and After Effects"
Thanks to Harm (and others) for some great forum threads that I could refer people to for good advice.hi ,
1.) try to avoid ' into correspondig field of ' option in select query
use ' into table tanle_name'.
2.) fro all the select queries containing addition
' FOR ALL ENTRIES IN TABLE_NAME' check the condition
IF TABLE_NAME[] IS NOT INITIAL.
ENDIF
before the select query.
3.) before the read statement sort the table by any key field and
use the addition BINARY SEARCH with READ statement.
4.) For modifying the internal table always use index.
5.) <b>never use select statement inside loop.</b>
for ur case u can use internal table for selecting 'NAME1' from 'KNA1'.
Inside the loop perform the read operation for this internal table.
in the same way avoid the other select statement which u have used in the loop. -

Is there a different version of the firmware perhaps an older version available for download somewhere? Or is there something I am doing wrong?
Any help would be greatly appreciated.
We have 2 - srw2024's and 2- srw2016's. Issue only on the one with the fw upgrade.
Thanks.Here is what I've found to be useful and so far seems like a fix for myself.
I downloaded an older firmware version 1.0086 from here

The other 2 versions may help some other people on this forum.
Uploaded it through the serial port with Xmodem.
So far I've been able to boot and now access through web interface. I will post later on how it is doing later in the day. -
I am new to the bdc .
i have gone to SHDB and created a new recording for the some T-code .
After that i have created a prog (transfer from recording ) .
i got some values in the file in my presenation server.
i got default code generated .
I have to declare the internal table of some time .
may i know of which type should i declare my internal table ??

Timing for Data Acquisition Using Notifiers
I'm trying to use notifiers to transfer data from an acquisition (master) loop to the slave loop. I want data to be transferred for analysis only when the VI is in a certain state - not in all states. That's why I'm preferring to use notifiers instead of queues (I want all data collected during the other states to be disregarded). I have attached a simplified version of what I'm trying.
The master loop generates a data point every second. The slave loop is in a "delay" state for 5 seconds and then in "acquire" state for 3 seconds. Given this architecture I would expect no data for 5 seconds and then 3 data points to be plotted during "acquire" state because only one data point is generated per second. But for some reason I get 5 or 6 data points during every acquire cycle. I haven't figured out why I get 5-6 data points instead of 3. It probably has to do with the timing functions I'm using.
Thanks!

Notifier Data Transfer Template.vi 62 KBHere is an example of a race condition without the use of local or global variables. What is happening is that the notifier is already queued up with a value even before the Elapsed Timer has even started. So one extra value will be in the output array. Also, depending on how the parallel loops perform (which goes first), there may be an extra value queued up before the Time Elapsed event could fire. Typically, when I ran it, I got an array size of 6 at first, and then it went down to 5. Clearly the architecture is not right for what you want to do. Instead of depending on timers and parallel loop timing, you could receive all the values queued and just discard the ones you don't want.

I even tried to re-write the "run method" in tthe invocable in a way that caused it to, in a loop, perform a delay and then re-try its calculations when it received a runtime exception with the text "Storage is not configured" causing the retreival a new named cache each time but this did not help - it never seemed to recover...
Since I dont see any of my application classes in the "class cast" trace-back I assume it is an Coherence internal problem or can you thiink about some user programming error that could cause it? I am by the way not using any long or "Long in my application...

MagnusHi Magnus,
The log you provided seems to indicate that the problem was caused by the de-serialization of the “AggregateFilterRequest” message. The only explanation we have is that you are using a custom Filter that has asymmetrical serialization/deserialization routines, causing this failure. Could you please send us the corresponding client code?
Meanwhile, we will open a JIRA issue, to make sure that Coherence handles this kind of error more gracefully.
