How to improve performance of DSO activation

Hi all,
We have created a DSO which is updated daily from another DSO. The extraction is from the Active table of the source DSO, so all records are extracted, in this case roughly 1,000,000 records. (we cannot use delta update for this particular DSO)
Because of the large number of records, the activation of the data in the target DSO is quite slow (ca 20 minutes).
My question: Is there any way that we can analize where exactly the time is lost during the activation and how we can improve the performance? Is it for example possible to deactivate the Change log?
Note that I am already familiar with RSODSO_SETTINGS, and also, we do not want to switch to write-optimized DSO.
Thank you in advance for your help.

Hi
DSO Activation can be improve by unchecking the "SIDs Generation upon Activation" check box in the DSO settings as it takes lot of time to create SIDs while activations. We can go ahead with this option only when we dont have any reports based on that DSO
Thanks & Regards

How to improve performance of MediaPlayer?

I tried to use the MediaPlayer with a On2 VP6 flv movie.
Showing a video with a resolution of 1024x768 works.
Showing a video with a resolution of 1280x720 and a average bitrate of 1700 kb/s leads to a delay of the video signal behind the audio signal of a couple of seconds. VLC, Media Player Classic and a couple of other players have no problem with the video. Only the FX MediaPlayer shows a poor performance.
Additionally mouse events in a second stage (the first stage is used for the video) are not processed in 2 of 3 cases. If the MediaPlayer is switched off, the mouse events work reliable.
Does somebody know a solution for this problems?
Cheers

Above is the query.If we run inner query it takes few second to execute but while we are summing up the same amount and bill_Seq using inline view, it takes time to execute it.
Note: Count of rows selected from inner query will be around >10 Lac

The two DISTINCTs are redundant, as UNION results in unique records, as a set can't have duplicates.
Other than that the query is not formatted and unreadable, and you didn't provide a description of the tables involved.
Your strategy seems to be maximum help from this forum with minimum effort from yourself, other than hitting copy and paste.

How to improve performance for Custom Extractor in BI..

HI all,
I am new to BI and started working on BI for couple of weeks.. I created a Custom Extractor(Data View) in the Source system and when i pull data takes lot of time.. Can any one respond to this, suggesting how to improve the performance of my custom Extractor.. Please do the needfull..
Thanks and Regards,
Venugopal..

Dear Venugopal,
use transaction ST05 to check if your SQL statements are optimal and that you do not have redundant database calls. You should use as much as possible "bulking", which means to fetch the required data with one request to database and not with multiple requests to database.
Use transaction SE30 to check if you are wasting time in loops and if yes, optimize the algorithm.
Best Regards,
Sylvia

Hi Raj,
How is your direct access datasource built ? Is this a standard datasource or generic datasource on any view/table/function module. This strengthens my second point.
Suppose you built a virtual cube on direct access datasource built on AUFK table with Order as primary key (Order master data). when you use Order as selection on query built on this virtual cube then it retrievies the data faster than firing the query on other selections.
If your selections are different. You can possibly create a secondary index on the table with selections used in query.

How to improve performance when there are many TextBlocks in ItemsControl items?

Hi,
I'm trying to find a way to improve performance for a situation when there is an ItemsControl using UI and Data virtualization and each item on that control has 36 TextBlocks. Basically the item is a single string. There are so many TextBlocks
to allow assigning different brushes to different parts of the string. Performance of this construction is terrible. I have 37 items visible on the screen and if I try to scroll up or down it scrolls into the black space and then it takes a second or two to
show the items.
I tried different things. For example, the most successful performance-wise was to replace TextBlocks with Borders and then draw bitmaps. In other words, I prepared 127 bitmaps for each character (I need ASCII only) and then I used those bitmaps
to set Border.Backgrounds. It improved performance about 1.5 - 2 times but it consumed much more memory (which is not surprising, of course). Required amount of memory is so big that it throws OutOfMemoryException on 512MB emulator but works on 1GB. As a result
I don't thing it is a good solution.
Another thing that worked perfect is to replace 36 TextBlocks with only 6 TextBlocks. In this case the performance improvement is about 5 - 10 times but I lose the ability to set different colors to different parts of the string. It seems that
the performance degrades dramatically with the increase of number of TextBlocks. Is there another technique to draw strings where literally each character can be of different color with decent performance?
Thank you
Alex

Using Runs inside TextBlocks gives approximately the same improvement as using bitmaps 1.5 - 2 times faster but it is not even close to the case with just a couple of TextBlocks in the ItemsControl item. Any other ideas?

What and where to change parameters and values ?Well, maybe my previous post was not clear enough, but if you want to keep your job, you shouldn't change anything else on init parameter and you shouldn't fall in the Compulsive Tuning Disorder.
Everyone who advise you to change some parameters to some value without any more info shouldn't be listen.

How to check if a DSO Active Table is being used in any look-up's?

Hi Gurus,
We have a DSO that is being loaded on a weekly basis. Now this DSO is being loaded right from the time our project went live. There are no reports built on top of this DSO and the DSO is not being used as a Data Mart i.e. it doesn't feed any other DSO's or InfoCube's. Also this DSO is not being used in any MultiProviders.
So the only sensible reason for using this DSO that we can think of is that the data from this DSO is being 'looked up' by some other DSO's or InfoCube at run-time. So Is it possible to check if the active data table of an DSO is being ;looked up' at run time by some other data loads? I already tried using an 'Where Used List' on the active data table of the DSO, but it didn't show any results.
Thanks
Arvind

Try the following:
Check the table RSAABAP in SE16, you can search the technical name of DSOs active table in field EDIC.
You get all Code-IDs, where this table is used in ABAP coding.
In RSAROUT you can check, which code-type it is.
Now you know, if the DSO is used in any routines.
Hope this helps.
Regards
Tobias
