Conversion of Characteristic Values to SIDs. Load Very slow

Hi Experts,
                 We have a slow load issue when loading from a Write-Optimized DSO into an InfoCube. 8 millon recs in 10 hours.
We check the start, end, and rules routines and every is ok but for all the package the load was very slow in the Conversion of Characteristic Values to SIDs.
Can any help me with this?
Thanks a lot,
Alejandro

Hi,
It is because the SIDs Generation upon Activation flag is unchecked at DSO level .
One recommendation will be to switch on the property of the DSO SIDs Generation upon Activation flag .
Are there any secondary indexes also in DSO ?
You can try deleting them also during loading the data from DSO to cube .
Also load your master data first and activate it before loading it to cube.
Thanks,

  • Conversion of Characteristic Values to SIDs is taking long time

    Hi Experts,
        Cube load is taking more than 7 hrs to complete for 6 million records. Max time is at Conversion of Characteristic Values to SIDs. Cube consists of 500 fields. Load is from DSO to Cube. DSO has 10 fileds with no SID flag check for activation. Remaining fields in the CUBE are pouplated looking in to other DSO's. Start and End routines are executing very fast. How to fasten Conversion of Characteristic Values to SIDs step.  I need to load 15 million records daily as part of delta. any suggestions.
    Thanks

  • Performance - Conversion of characteristic values to SID

    Greetings:
    Yesterday I load 556.000 record into an infocube.
    No transformations of any kind. Direct assign for every infoobject. Very simple
    It lasted 1 h 30m to complete the loading.
    It started loading  7 datapackage of 50.000 records each.
    I realized that 3 of those datapackage (#2, #4 and #7) lasted from 41:47min to 41:59min in the "Conversion of characteristic values to SID" task. The other 5 lasted ... seconds.
    Any idea of that could be going on during this conversion?
    I don't understant why some datapackages last so long and other don't.
    Does anybody has any idea about this?
    Thanks in regards.
    Guillermo

    Hi Daniel,
    The SID generation is based upon the Dimension Table and Master data.
    If you see the dimension table can be build with different types like:
    one to many
    many to one
    many to many
    one to one
    So, if the dimension's for that datapacket data is many to many then it has to get all the relations and then it has to assign an SID.
    If it is one to one then there will be no more work to be done by the system to assign the SID's
    Hope you understood the back-end process.
    With Regards,
    Ravi Kanth.

  • Slow dataload into Infocube- Conversion of Characteristic values to SIDs

    Hi All,
    we are facing a slow delta load issue when loading from a DSO into an InfoCube ( approx 150,000 recs).
    After checking the monitor found that
    - The Conversion of Characteristic values to SIDs is taking time
    - The Start Routine time is real quick ( in secs)
    The underlying DSO is hugh and there is no SIDs Generation upon Activation flag set for it
    Master data is loaded first and than we are loading the transaction data.
    i've tried refreshing the stats of the Cube, Reduce the size of the data package,
    Deletion of Indexes than Loading and recreation of Indexes, no joy at all.
    Any comments and recommendations are much appreciated.
    Thanks,
    Natalie

    Hi Natalie,
    The problem for your slow delta load from DSO to cube is because the SIDs Generation upon Activation flag is unchecked at DSO level .
    Becasue of which your activation is faster but your loading from DSO to cube will be slower as you only mentioned that SIDs are being generated .
    One recommendation will be to switch on the property of the DSO SIDs Generation upon Activation flag .
    Are there any secondary indexes also in DSO ?
    You can try deleting them also during loading the data from DSO to cube .
    I guess your change log table is also huge in this case . If possible we can think of deleting the log table also . Then for the new records let it get filled .
    Hope the above reply was helpful.

  • Conversion of Characteristic Values to SIDs

    Does anyone know why this DTP step would take 15 - 20 min for 10,000 records?

    Hi Hank,
    Just check out if there are any Indexes created on that cube,if yes pls delete the indexes and Load the Data and then Create the Indexes.
    Also check with the Basis team for the Server Load,which shud not be a issue as u said this is the Only job that is Running.Hope u have loaded master data before transaction Data.

  • Please help: Course loads very slow and takes almost 100% cpu and 1.08 GB memory

    The total page number is 129. We used Captivate 5.5. We have several Webpage widgets and a few videos. I tried to take out the web widgets and the videos, however, the course still loads very slow.
    I would really appreciate if someone can give somve suggestion.
    Thank you very much.

    Captain Ibuprofen, we actually continued having the slowness problem in the past week. Then one of our developers found out the reason: as same as yours, caused by the page number widget. I wish we would have seen your response earlier. But yeah, so now we took out the page number widget and everything goes normal.
    Also thanks for the tips on using the cpInfoCurrentSlide variable when adding the slide number. Thanks Andy.

  • ITunes loads very slow

    With over 48000 songs, itunes loads very slow. Thinking it my be my pc I loaded it onto a new pc and get the same results. Is there anything I can do to getit to load under 5 seconds at least?

    Dear Apple,
    I need to complain about the same problem. I have 1/10th the songs in i-Tunes (~4800) and I cringe every time I want to start the program. The same delay happens anytime I load or switch a CD to import a song.
    Google can load a billion links in a blink; can't you load a millionth of this info in the same amount of time? Any hints would be greatly appreciated.
    Frustrated,

  • External HD slow in finder: list loading very slow

    I have a 1 TB HD that is very slow with loading the files in finder.
    This has not been a problem with my 8 year old pc at home. Where I run macdrive to
    acces the files. The HD is formatted in HFS+
    When I press a folder it looks like if Finder first loads all the files in that folder and then when it's done loading it shows me the files. Is this a settings thingy or is the finder just acting like an idiot. Because it's extremely annoying and stops my workflow.
    Ones it's loaded I can switch from different folders that I've previously viewed and there is no problem.
    I hope someone can tell me what's going on inside the computer.
    Thanxs.

    It takes forever to show up in finder. I've never had this problem before on the iMacs (white and silver), eMacs, Macbooks. And now I'm working on a tower mac with 4gb and it starts acting like a you know what...I'm sorry if I sound very annoyed but I am very annoyed. I checked Disc Utility, did a repair scan but it will take 22 hours. The academy is not open for 22 hours. Looked for the same problem but no useful info which tells me that I can do something about it or not.
