Check Data Values, Generates Navigation Data steps taking more time

Hi,
In the Masterdata load to 0MAT_PLANT
The step - "Updating attributes for InfoObject 0MAT_PLANT" used to take a Maximum if 23 minutes for a data package size of 100,000 records till three days ago with the constituent steps "Check Data Values","Process Time-Independent Attributes" and "Generates Navigation Data" taking 5,4 and 12 minutes respectively.
For the last three days the step "Updating attributes for InfoObject 0MAT_PLANT" is taking 58-60 minutes for the same for data package size of 100,000 records with the constituent steps "Check Data Values","Process Time-Independent Attributes" and "Generates Navigation Data" taking 12,14 and 22 minutes respectively.
Can anyone please explain what is needed to speeden the dataload back to its previous timing e.g. if  tables indexes need to built for 'P' or 'SID' table of Mat_plant.
An explanation of why the delay could be happening in the above steps will be really great.
regards,
Kulmohan

Hi Kulmohan Singh,
I think there may be a difference between the first update and second update is the 100,000 records is
already in your 0MAT_PLANT.
If you update the 0MAT_PLANT in twice, The Modify statement should loop the Q table of
0MAT_PLANT that was already have the 100,000 records in it,so the upload speed was slowly.
Hope it helpful you.
Regards,
James.

    Hi.
    The Select statment accessing MSEG Table is Slow Many a times.
    To Improve the performance of  MSEG.
    1.Check for the proper notes in the Service Market Place if you are working for CIN version.
    2.Index the MSEG table
    2.Check and limit the Columns in the Select statment .
    Possible Way.
    SELECT MBLNR MJAHR ZEILE BWART MATNR WERKS LIFNR MENGE MEINS
    EBELN EBELP LGORT SMBLN BUKRS GSBER INSMK XAUTO
    FROM MSEG
    INTO CORRESPONDING FIELDS OF TABLE ITAB
    WHERE WERKS EQ P_WERKS AND
    MBLNR IN S_MBLNR AND
    BWART EQ '105' .
    Delete itab where itab EQ '5002361303'
    Delete itab where itab EQ  '5003501080' 
    Delete itab where itab EQ  '5002996300'
    Delete itab where itab EQ '5002996407'

  • Deletion of Data Mart Request taking more time

    Hi all,
    One of the Data Mart process(ODS to Infocube) has failed.
    Im not able to delete the request in Infocube.
    When delete option executed, its taking more time while im monitoring that job in SM37 and its not getting completed.
    The details seen in the Job Log is as shown below,
    Job started                                                                  
    Step 001 started (program RSDELPART1, variant &0000000006553, user ID SSRIN90)
    Delete is running: Data target BUS_CONT, from 376,447 to 376,447             
    Please let me know your suggestions.
    Thanks,
    Sowrabh

    Hi,
    How many records are there in that request. Usually when you try to delete out a request it takes more time. Depending on the data volume in the request the deletion time will vary.
    Give it some more time and see if it finishes. To actually know if the job is doing anything, goto SM50/51 and look at whats happening.
    Cheers,

  • How to extract the date value of IBOR date="12/12/2009"

    How to extract the date value of <IBOR date="12/12/2009">?

    Hi,
    The date is an attribute of element IBOR. So you must use "@date" in the xpath expression :
    WITH ibors AS (
    SELECT xmltype('<?xml version="1.0" encoding="utf-8"?>
    <IBOR date="12/12/2009">
    <LIBOR currency="USD">
    <OneYear>1.38875</OneYear>
    </LIBOR>
    </IBOR>
    ') ibor_xml
    FROM dual
    SELECT i.ibor_date, i.ibor_oneyear
    FROM ibors,
    XMLTABLE(
    '//IBOR'
    PASSING ibors.ibor_xml
    COLUMNS
    ibor_date VARCHAR2(20) PATH '/IBOR/@date',

    Regards n Thanks
    kgb

    Hi kgbm,
    This my point of view:
    1)DataMart: in BI you use this term for identify a specific area of analysis in your DataWarehouse. Generally it is obtained with an aggregation of data of other structures, or combining internal data with external data.
    2)Generate Export D.S.: it is the technical tool to obtain an extractor to feed other structures, called DataMart.

  • DTP step taking longer time

    Hello Experts
    As Iam new to SDN I tried to find an answer to this issue. Please find below is the Issue
    There is a process chain. In this PC, After deleting the Index step, there is a DTP step, which updates the Cube with one DSO; the first DTP step is much delayed for update to cube. But where as the immediate DTP step to the same cube with another DSO is finishing so faster.
    The prob is with the first DTP step which updates the cube frm DSO In this there is one Job with the namingconvention shown as BIDTPR_545787_1 was running more than 10000sec to update the Cube. Dont know why this job is running beyond so much time, where as it usually prior to some days back completes within 3000 secs.
    Now the prob. is that the Data loading performance of the Prod system effected, where this DTP step is ruuning beyond time. Please can someone suggest how to find and resolve this issue as not sure why the below kind of JOBS are running for more time causing the PC much delayed for completion
    BIDTPR_545787_1
    BIDTPR_545689_1 etc of the First DTP are running longer. Pls help!
    Regards
    MD

    Hi
    There could have been many reasons like
    during that particular DTP is scheduled,there will not be neough work processors,this is due to the some other long running loads/jobs are running and which would have been occupied.hence during this DTP runs,parallely crosscheck in SM12,SM50&SM51.
    And also check that particular job in SM37 and understand where does its taking more time.
    There could have been expensive select statement,if any routines used in the transformations.
    Try to find out this.
    Regards
    Jagadish

  • Create Index Step taking long time

    I have a create index step in process chain for a infocube. The Create Index step is takes more time. The requests in this cube are rolled up and compressed. The batch process are also avaliable. But still the create index step takes more time. Any suggestions to reduce the time of create index step?

    Hi,
    If you have more Data in Cube then it will take some time..check any Dumps in ST22 and SM21. Ask Basis Team any Error messages in DB02 and check.
    Else goto to RSRV
    Tests in Transaction RSRV --> Database --> Database Indices of an InfoCube and Its Aggregates
    Give Cube name and execute it and see the errors then if any RED color, ckick on Repaire Icon and see.
    Thanks

  • Taking More Time while inserting into the table (With foriegn key)

    Hi All,
    I am facing problem while inserting the values into the master table.
    The problem,
    Table A -- User Master Table (Reg No, Name, etc)
    Table B -- Transaction Table (Foreign key reference with Table A).
    While inserting the data's in Table B, i need to insert the reg no also in table B which is mandatory. I followed the logic which is mentioned in the SRDemo.
    While inserting we need to query the Table A first to have the values in TableABean.java.
    final TableA tableA= (TableA )uow.executeQuery("findUser",TableA .class, regNo);
    Then, we need to create the instance for TableB
    TableB tableB= (TableB)uow.newInstance(TableB.class);
    tableB.setID(bean.getID);
    tableA.addTableB(tableB); --- this is for to insert the regNo of TableA in TableB.. This line is executing the query "select * from TableB where RegNo = <tableA.getRegNo>".
    This query is taking too much time if values are more in the TableB for that particular registrationNo. Because of this its taking more time to insert into the TableB.
    For Ex: TableA -- regNo : 101...having less entry in TableB means...inserting record is taking less than 1 sec
    regNo : 102...having more entry in TableB means...inserting record is taking more than 2 sec
    Time delay is there for different users when they enter transaction in TableB.
    I need to avoid this since in future it will take more time...from 2 sec to 10 sec, if volume of data increases mean.
    Please help me to resolve this issue...I am facing it now in production.
    Thanks & Regards
    VB

    Hello,
    Looks like you have a 1:M relationship from TableA to TableB, with a 1:1 back pointer from TableB to TableA. If triggering the 1:M relationship is causing you delays that you want to avoid there might be two quick ways I can see:
    1) Don't map it. Leave the TableA->TableB 1:M unmapped, and instead just query for relationship when you do need it. This means you do not need to call tableA.addTableB(tableB), and instead only need to call tableB.setTableA(tableA), so that the TableB->TableA relation gets set. Might not be the best option, but it depends on your application's usage. It does allow you to potentially page the TableB results or add other query query performance options when you do need the data though.
    2) You are currently using Lazy loading for the TableA->TableB relationship - if it is untriggered, don't bother calling tableA.addTableB(tableB), and instead only need to call tableB.setTableA(tableA). This of course requires using TopLink api to a) verify the collection is an IndirectCollection type, and b) that it is hasn't been triggered. If it has been triggered, you will still need to call tableA.addTableB(tableB), but it won't result in a query. Check out the oracle.toplink.indirection.IndirectContainer class and it's isInstantiated() method. This can cause problems though in highly concurrent environments, as other threads may have triggered the indirection before you commit your transaction, so that the A->B collection is not up to date - this might require refreshing the TableA if so.
    Change tracking would probably be the best option to use here, and is described in the EclipseLink wiki:
    http://wiki.eclipse.org/Introduction_to_EclipseLink_Transactions_(ELUG)#Attribute_Change_Tracking_Policy

    Hello Friend,
    You query will definitely take more time or even fail in PROD,becuase the way it is written. Here are my few observations, may be it can help :-
    1. XLA_AR_INV_AEL_SL_V XLA_AEL_SL_V : Never use a view inside such a long query , becuase View is just a window to the records.
    and when used to join other table records, then all those tables which are used to create a view also becomes part of joining conition.
    First of all please check if you really need this view. I guess you are using to check if the records have been created as Journal entries or not ?
    Please check the possbility of finding it through other AR tables.
    2. Remove _ALL tables instead use the corresponding org specific views (if you are in 11i ) or the sysnonymns ( in R12 )
    For example : For ra_cust_trx_types_all use ra_cust_trx_types.
    This will ensure that the query will execute only for those ORG_IDs which are assigned to that responsibility.
    3. Check with the DBA whether the GATHER SCHEMA STATS have been run atleast for ONT and RA tables.
    You can also check the same using
    SELECT LAST_ANALYZED FROM ALL_TABLES WHERE TABLE_NAME = 'ra_customer_trx_all'.
    If the tables are not analyzed , the CBO will not be able to tune your query.
    4. Try to remove the DISTINCT keyword. This is the MAJOR reason for this problem.
    5. If its a report , try to separate the logic in separate queries ( using a procedure ) and then populate the whole data in custom table, and use this custom table for generating the
    report.
    Thanks,
    Neeraj Shrivastava

  • Essbase Calculation Script taking more time in new environment

    Hi Everyone:
    We have four environments in our implementation.
    1. DEV Environment - 64 bit Essbase Version 11.1.1.3
    2. PreProd Environment - 32 bit Essbase Version 9.3.0
    3. PreProd Environment - 64 bit Essbase Version 11.1.1.3
    In the above mentioned environment PreProd Environment - 64 bit Essbase Version 11.1.1.3 is a newly installed
    environment.
    We have migrated our Application from PreProd Environment - 32 bit Essbase Version 9.3.0 to PreProd Environment - 64 bit Essbase Version 11.1.1.3. A calculation script that takes only 20 minutes in 32 bit PreProd is taking more than
    5 and half hours in newly installed 64 bit PreProd.
    We have also migrated our Application from DEV Environment - 64 bit Essbase Version 11.1.1.3 to PreProd Environment - 64 bit Essbase Version 11.1.1.3. The calculation script that takes only 20 minutes in 64 bit Dev is taking more than 5 and half hours in newly installed 64 bit PreProd.
    All the server settings and cache setting everything looks similar in all the three environments.
    Please advice us what are all the possibilities that creates the issue.

    Data file cache:32768
    The all above settings are identical both servers.
    In New server ,only one script that is taking more time but remaining scripts are working fine with less time.
    We also did one test cause that splitting the script in to multiple and executed ,in this cause the script where we are using direct assigning value from member(say A1) to another member(Say A2) is taking more time.But same scripts we executed in old server it executes fine.
    Still we are not able to find out exact root cause for this issue.
    Could please anyone help me to resove this issue.

  • Snapshot Refresh taking More Time

    Dear All,
    We are facing a Snapshot refresh problem currently in Production Environment.
    Oracle Version : Oracle8i Enterprise Edition Release 8.1.6.1.0
    Currently we have created a Snapshot on a Join with 2 remote tables using Synonyms.
    ex:
    CREATE SNAPSHOT XYZ REFRESH COMPLETE WITH ROWID
    AS
    SELECT a.* FROM SYN1 a, SYN2 b
    Where b.ACCT_NO=a.ACCT_NO;
    We have created a Index on the above Snapshot XYZ.
    Create index XYZ_IDX1 on XYZ (ACCT_NO);
    a. The Explain plan of the above query shows the Index Scan on SYN1.
    If we query above Select Statement,it hardly takes 2 seconds to exedute.
    b. But the Complete Refresh of Snapshot XYZ is almost taking 20 Mins for just truncating and inserting 500 records and is generating huge Disk Reads as SYN1 in remote table consists of 32 Million records whereas SYN2 contains only 500 Records.
    If we truncate and insert inot a table as performed by the Complete refresh of Snapshot,it hardly takes 4 Seconds to refresh the table.
    Please let me know what might be the possible reasons for the Complete refresh of Snapshot taking more time.

    Dear All,
    While refreshing the Snapshot XYZ,I could find the following.
    a. Sort/Merge operation was performed while inserting the data into Snapshot.
    INSERT /*+ APPEND */ INTO "XYZ"
    SELECT a.* FROM SYN1 a, SYN2 b Where b.ACCT_NO=a.ACCT_NO;
    The above operation performed huge disk reads.
    b. By Changing the session parameter sort_area_size ,the time decreased by 50% but still the disk reads are huge.
    I would like to know why Sort/Merge Operation is performed in the above Insert?

  • Oracle 11g: Oracle insert/update operation is taking more time.

    Hello All,
    In Oracle 11g (Windows 2008 32 bit environment) we are facing following issue.
    1) We are inserting/updating data on some tables (4-5 tables and we are firing query with very high rate).
    2) After sometime (say 15 days with same load) we are feeling that the Oracle operation (insert/update) is taking more time.
    Query1: How to find actually oracle is taking more time in insert/updates operation.
    Query2: How to rectify the problem.
    We are having multithread environment.
    Thanks
    With Regards
    Hemant.

    Hi Nicolas,
    Just a short explanation:
    If you have a table with 1 column (let's say a number). The table is empty and you have an index on the column.
    When you insert a row, the value of the column will be inserted to the index. To insert 1 value to an index with 10 values in it will be fast. It will take longer to insert 1 value to an index with 1 million values in it.
    My second example was if I take the same table and let's say I insert 10 rows and delete the previous 10 from the table. I always have 10 rows in the table so the index should be small. But this is not correct. If I insert values 1-10 and then delete 1-10 and insert 11-20, then delete 11-20 and insert 21-30 and so on, because the index is sorted, where 1-10 were stored I'll now have empty spots. Oracle will not fill them up. So the index will become larger and larger as I insert more rows (even though I delete the old ones).
    The solution here is simply revuild the index once in a while.
    Hope it is clear.

    [www.orbiumsoftware.com]Hmmm, index space not reused ? Index rebuild once a while ? That was what I understood from your previous post, but nothing is less sure.
    This is a misconception of how indexes are working.
    I would suggest the reading of the following interasting doc, they are a lot of nice examples (including index space reuse) to understand, and in conclusion :

    "+Index Rebuild Summary+
    +•*The vast majority of indexes do not require rebuilding*+

    please let me know why it taking more time in INDEX RANGE SCAN compare to the full table scan?Suresh,
    Any particular reason why you have a non-default value for a hidden parameter, optimizercost_based_transformation ?
    On my 10.2.0.1 database, its default value is "linear". What happens when you reset the value of the hidden parameter to default?
