Query Takes Longer time as the Data Increases.
Hi ,
We have one of the below Query which takes around 4 to 5 minutes to retrieve the data and this appears to be very slow as the data grows.

Hi Centinul,
I tried your modified version of the query on the test Machine.It used Quite a lot of Temp space around 9GB and Finally ran out of disk space.
On the test Machine i have generated stats and Executed the Queries but in the production our stats will be always Stale reason is
In the Morning we have 3000 records in Tibex_Order and as the day progresses data will be increment and goes upto 20 millions records by the end of day and we generate the stats and Truncate the Transaction tables(Tibex_Order=20 Million records) and next day our stats will be stale and if the user runs any Query then they will take Ages to retrieve Example is the below one.

Hi All,
We used report generation tool kit to generate the report on word and with other API 's under it,we get good reports .
But when the data points are more (> 100 on all channels) it take a long time to write all data and create a table in the word and generate report.
Any sugegstions how to make this happen in some seconds .
Please assist.Well, I just tried my suggestion. I simulated a 24-channel data producer (I actually generated 25 numbers -- the first number was the row number, followed by 24 random numbers) and generated 100 of these for a total of 2500 double-precision values. I then saved this table to Excel and closed the file. I then opened Word (all using RGT), wrote a single text line "Text with Excel", inserted the previously-created "Excel Object", and saved and closed Word.
First, it worked (sort of). The Table in Word started on a new page, and was in a very tiny font (possibly trying to fit 25 columns on a page? I didn't inspect it very carefully). This is probably "too much data" to really try to write the whole table, unless you format it for, say, 3 significant figures.
Now, timing. I ran this four times, two duplicate sets, one with Excel and Word in "normal" mode, one in "minimized". To my surprise, this didn't make a lot of difference (minimized was less than 10% faster). Here are the approximate times:
Generate the data -- about 1 millisecond.
Write the Excel Report -- about 1.5 seconds
Write the Word Report -- about 10.5 seconds
Seems to me this is way faster than trying to do this directly in Word.

Query takes long time on multiprovider
Hi,
When i execute a query on the multiprovider, it takes very long time. it doesnt show up the results also. It just keep processing. I have executed the report only for one day but still it doesnt show any result. But when i execute on the cube, it executes quickly and shows the result.
Actually i added one more cube to the multiprovider and ten transported that multiprovider to QA and PRD. Transportation went on successfully. After this i am unalbe to execute the reports on that multiprovider. What might be the cause? your help is appreciated.
Thanks
AnnieHi Annie.......
Checklist for the performance of a Query........from a DOc........
1. If exclusions exist, make sure they exist in the global filter area. Try to remove exclusions by subtracting out inclusions.
2. Use Constant Selection to ignore filters in order to move more filters to the global filter area. (Use ABAPer to test and validate that this ensures better code)
3. Within structures, make sure the filter order exists with the highest level filter first.
4. Check code for all exit variables used in a report.
5. Move Time restrictions to a global filter whenever possible.
6. Within structures, use user exit variables to calculate things like QTD, YTD. This should generate better code than using overlapping restrictions to achieve the same thing. (Use ABAPer to test and validate that this ensures better code).
7. When queries are written on multiproviders, restrict to InfoProvider in global filter whenever possible. MultiProvider (MultiCube) queries require additional database table joins to read data compared to those queries against standard InfoCubes (InfoProviders), and you should therefore hardcode the infoprovider in the global filter whenever possible to eliminate this problem.
8. Move all global calculated and restricted key figures to local as to analyze any filters that can be removed and moved to the global definition in a query. Then you can change the calculated key figure and go back to utilizing the global calculated key figure if desired
9. If Alternative UOM solution is used, turn off query cache.
10. Set read mode of query based on static or dynamic. Reading data during navigation minimizes the impact on the R/3 database and application server resources because only data that the user requires will be retrieved. For queries involving large hierarchies with many nodes, it would be wise to select Read data during navigation and when expanding the hierarchy option to avoid reading data for the hierarchy nodes that are not expanded. Reserve the Read all data mode for special queriesu2014for instance, when a majority of the users need a given query to slice and dice against all dimensions, or when the data is needed for data mining. This mode places heavy demand on database and memory resources and might impact other SAP BW processes and tasks.
11. Turn off formatting and results rows to minimize Frontend time whenever possible.
12. Check for nested hierarchies. Always a bad idea.
13. If u201CDisplay as hierarchyu201D is being used, look for other options to remove it to increase performance.
14. Use Constant Selection instead of SUMCT and SUMGT within formulas.
15. Do review of order of restrictions in formulas. Do as many restrictions as you can before calculations. Try to avoid calculations before restrictions.
16. Check Sequential vs Parallel read on Multiproviders.
17. Turn off warning messages on queries.
18. Check to see if performance improves by removing text display (Use ABAPer to test and validate that this ensures better code).
19. Check to see where currency conversions are happening if they are used.
20. Check aggregation and exception aggregation on calculated key figures. Before aggregation is generally slower and should not be used unless explicitly needed.
21. Avoid Cell Editor use if at all possible.
22. Make sure queries are regenerated in production using RSRT after changes to statistics, consistency changes, or aggregates.
23. Within the free characteristics, filter on the least granular objects first and make sure those come first in the order.
24. Leverage characteristics or navigational attributes rather than hierarchies. Using a hierarchy requires reading temporary hierarchy tables and creates additional overhead compared to characteristics and navigational attributes. Therefore, characteristics or navigational attributes result in significantly better query performance than hierarchies, especially as the size of the hierarchy (e.g., the number of nodes and levels) and the complexity of the selection criteria increase.
25. If hierarchies are used, minimize the number of nodes to include in the query results. Including all nodes in the query results (even the ones that are not needed or blank) slows down the query processing. The u201Cnot assignedu201D nodes in the hierarchy should be filtered out, and you should use a variable to reduce the number of hierarchy nodes selected.

Oracle SQL Select query takes long time than expected.
Hi,
I am facing a problem in SQL select query statement. There is a long time taken in select query from the Database.
The query is as follows.
select /*+rule */ f1.id,f1.fdn,p1.attr_name,p1.attr_value from fdnmappingtable f1,parametertable p1 where p1.id = f1.id and ((f1.object_type ='ne_sub_type.780' )) and ( (f1.id in(select id from fdnmappingtable where fdn like '0=#1#/14=#S0058-3#/17=#S0058-3#/18=#1#/780=#5#%')))order by f1.id asc
This query is taking more than 4 seconds to get the results in a system where the DB is running for more than 1 month.
The same query is taking very few milliseconds (50-100ms) in a system where the DB is freshly installed and the data in the tables are same in both the systems.
Kindly advice what is going wrong??

Hi All.
When i execute select query from View it takes about 00:00:45:12 sec to pull the data , but when i execute same query in some other system(different database with same table structure) it takes about 00:00:02:05 sec.
1)I have tried by dropped and recreated the index then i tried by exec dbms_stats.gather_table_stats procedure still no luck.
Please help me to understand the reason difference in response time
Thanks

Select query takes long time....
Hi Experts,
I am using a select query in which inspection lot is in another table and order no. is in another table. this select query taking very long time, what is the problem in this query ? Pl. guide us.
select bPRUEFLOS bMBLNR bCPUDT aAUFNR amatnr aLGORT a~bwart
amenge aummat asgtxt axauto
into corresponding fields of table itab
*into table itab
from mseg as a inner join qamb as b
on amblnr = bmblnr
and azeile = bzeile
where b~PRUEFLOS in insp
and b~cpudt in date1
and b~typ = '3'
and a~bwart = '321'
and a~aufnr in aufnr1.
Yusufhi
instead of using 'move to corresponding of itab' fields use 'into table itab'.....
coz......if u use move to corresponding it will search for all the appropriate fields then it will place u r data........instead of that declare apprpiate internal table and use 'into table itab'.
and one more thing dont use joins ......coz joins will decrease u r performance .....so instead of that use 'for all entries' ....and mention all the key fields in where condition ........
ok

DataBlAppend takes long time on registered data
Greetings! I'm using DIAdem 2012 on a Win7/64-bit computer (16GB memory and solid-state hard drive). I work with one tdms file at a time but that file can be up to 8GB so I bring it into the Data Portal via the Register Data option. The tdms file contains about 40 channels and each channel has about 50M datapoints. If it matters, the data type of each channel is U16 with appropriate scaling factors in the channel parameters. I display one channel in View and my goal is to set the two cursors on either side of an "event" then copy that segment of data between the cursors to a new channel in another group. Actually, there are about ten channels that I want to copy exactly the same segment out to ten new channels. This is the standard technique for programmatically "copying-flagged-data-points", i.e. reading and using the X1,X2 cursor position. I am using DataBlAppend to write these new channels (I have also tried DataBlCopy with identical results). My VBS script works exactly as I desire. The new channel group containing the segments will be written out as a tdms file using another script.
Copying out "small" segments takes a certain amount of time but copying larger segments takes an increasing amount of time, i.e. the increase is not linear. I would like to do larger segments but I don't like waiting 20-30 minutes per segment. The time culprit is the script line "Call DataBlAppend (CpyS, CurPosX1, CurPosX2-CurPosX1 +1, CpyT)" where CpyS and CpyT are strings containing the names of the source and target channels respectively (the empty target channels were previously created in the new group).
My question is, "is there a faster way to do this within DIAdem?" The amount of data being written to the new group can range from 20-160MB but I need to be able to write up to 250MB. TDMS files of this size can normally be loaded or written out quite quickly on this computer under normal circumstances, so what is slowing this process down? Thanks!Greetings, Brad!!
I agree that DataBlCopy is fast when working "from channels loaded in the Data Portal" but the tdms file I am working with is only "registered" in the portal. I do not know exactly why that makes a difference except that it must go out to the disk in order to read each channel. The function DataBlCopy (or Append) is a black box to me so I was hoping for some insight as to why it is behaving like it is under these circumstances. However, your suggestion to try the function DataFileLoadRed() may bear fruit! I wrote up a little demo script to copy out a "large" segment from a 8GB file registered in the portal using DataFileLoadRed and it is much, much faster! It was a little odd selecting "IntervalCount" as my method and the total number of intervals the same as the total number of data points between my begin and end points, and "eInterFirstValue" [in the interval] as the reduction method, but the results speak for themselves. I will need to do some thorough checking to verify that I am getting exactly the data I want but DataFileLoadRed does look promising as an alternative. Thanks!

Hello experts,
My users have queries on a MultiProvider. Today, the queries take a long time to load. When they want to put a filter on it, the selection pop-up takes a long time to show the possible selections.
Is there any way to find out what causes the long wait time? And what can I do about it, to optimize it?
Thanks in advance.Hi Erica,
Please check load on system(how many users are logged in..?)
Please check : [Checklist for Query Performance|http://sapbwneelam.blogspot.com/2007/10/checklist-for-query-performance.html] some tips for query performance.
Hope it Helps

Query takes long time from one machine but 1 sec from machine
I got a update query which is like a application patch which takes 1 sec from one machine.I need to apply that on the other machine where application is installed
Both applications are same and connecting to the same DB server.The query ran from second machine takes so long time ....
but i can update other thing from the secon machine.
IS there anything to do with page size ,line size
Urgent PleaseHI
Everything is same except from the diff machine.
Any client version issue because the script us so wide like 240 chars
PLAN_TABLE_OUTPUT
| Id | Operation | Name | Rows | Bytes | Cost |
| 0 | UPDATE STATEMENT | | | | |

| 2 | INDEX UNIQUE SCAN | PK_IDI_INTMST | | | |
Note: rule based optimization, PLAN_TABLE' is old version
10 rows selected.

Hi,
I have written a procedure that does the following :
1- Creates a temp table
2- INSERT /*+ append */ INTO <temp table>
(Select ......,
(select sum(amt)
from tbl1 b
where b.col1=a.col2 and b.col3=a.col3 and (b.col4=a.col4 OR b.col5=a.col5) ...
grp by col1,col2,col3),
from tbl1 a
where a.col1=.................
3- Query to delete the duplicate rows from the temp table....
4- Populate summarized data from TEMP TABLE to tbl1
5- drops the temp table.
Now this procedure takes around 2-3 mins for 2lakh records on local db, but when executed on production db takes 4 hours, when called from the application.
When the log was reviewed it took 4 hours just to insert the data into TEMP TABLE.
(*Note: this problem occurs only after executing the procedure for continuously 1 week or so. When the bea server is restarted and the application is run, it works fine. but after few days again the performance detiorates.
What could be the reason for this weird problem?!!! Please give me some tips, which can help me to figure out the problem.
Thanks
