Query Processing

Hi,
For large queries which DB parameter need to be increased.
SGA or PGA (currently 24M)
In SGA Shared pool is 150M, Java Pool 150M, Buffer Cache 256M, Large Pool 24M.
Which parameter in SGA need to be tuned to faster performance of the query.

Are you sure that the query EXECUTION PLAN is the same on both instances?
try EXPLAIN_PLAN for query on both instances and compare them...

  • Oracle 9i query processing

    Oracle 9.2.0.4.0
    Hi,
    Does oracle9i employ "Lazy Evaluation" in query processing?
    Thanks
    JN

    Lazy Evaluation applies in a number of cases, as does XPATH re-write. Both require structured (Schema based) XML documents. Can you provide more details about the queries you are interested in.

  • How to query Process Status from database in Project Server 2010

    Hello All,
    I am using Project Server 2010. 
    I need to query Process Status  from SQL. 
    where can I find Process Status in Database. 
    Thanks,
    Rohit

    Hi Rohit,
    you will not be able to find this information in reporting DB - the only database queries are supported.
    If you really want to go for an unsupported solution, you should be able to find related tables and how to join them in stored proc "MSP_WEB_SP_QRY_Statusing_ReadStatus" in published database.

  • Parallel Query processing in SQL server

    In stored procedure we are processing nearly 10 update statements with in a transaction, because  of synchronous query processing it is taking time to process all these queries ,I need to execute all the quires asynchronous processing can any

    Hi,
    For most cases the need of using asynchronous
    statements processing
    is resolving using Service Broker
    SQL Server Service Broker provides native support for messaging and queuing applications in the SQL Server Database Engine. Service Broker, internal or external processes can send and receive guaranteed, asynchronous messaging by using extensions to

  • How to Improve inserts into Template table for Query Processing

    Hi guys!
    I need your advice. How can i improve inserts into template table (/BI0/0P00000010 for exemple)? In my scenario i forced to load data from cube C_X to cubes C_1, C_2 and C_3.
    To get a goal i created a transformations and a DTP process with delta upload to each of cubes (C_1, C_2, C3). And that proccess takes about 3 hours! (it doesn't matter 1.000 or 100.000 records). But when i tried to load data with full update (with a filter) a proccess get data takes about 1 minutes.
    I traced process and saw that inserting into template table (which create each time when proccess started) take the longest time. How can i improve it?

    Hi Mahendar,
    It will require some efforts to investigate it so I propose to open a support ticket with Microsoft (through portal).
    Your first question interest me and I am not sure if you are doing proactive or reactive real time reporting. You can try with
    HBase for storing and retrieving data. HBase known for providing good read and write speed. If you are not comfortable writing HBase syntax then you can add an abstraction layer i.e. HIVE. It might take little more time when you
    query HBase from Hive.
    If you are doing real time analytic, then you can choose from Strom and Microsoft Azure Stream Analytic.
    Thanks and Regards,

  • Node variable in query - Processing type customer exit?

    We are on NW 2004S. I created a hierarchy for an info-object along with several nodes and child nodes.
    I also created a node variable in a query for this info-object. I have the following questions with regards to using node variables in a query.
    1) Can I use a node variable with processing type 'Customer Exit". My objective is to set the value of the node variable in the user exit.
    2) If answer to first question is "Yes", how would I code the node value in the user-exit - Example code or some pointers to that effect.
    I really appreciate your thoughts on this issue.
    Thanks,
    Sanjay

    Hi Sanjay,
    As far as I'm aware this hasn't changed in NW2004s, (in any case it still works), so:
    1)Yes you can, no difference with other type variables.
    2)In userexit EXIT_SAPLRRS0_001 (include ZXRSRU01).
    There's different options depending on at which stage you want to change it:
    http://help.sap.com/saphelp_nw2004s/helpdata/en/f1/0a56f5e09411d2acb90000e829fbfe/frameset.htm
    If you do a forum search on above technical names I think you'll find plenty of coding samples, but if you want something more specific, I'd be happy to help you out.

  • Query Processing Type in Reporting tools(Crystal, Webi Client, Deski etc)

    Hi,
    In tools like Webi, Crystal or Deski, query is executed serially. For Instance, if we have 3 dataproviders in a report, then first data provider fetches data and then second and the third one. In crystal Main report fetches the data first and followed by each subreport. Is there a way to tweak the tool settings and change this Serial query execution to Paralel? That is all the queries should fetch the data at the same time. It should not wait for other dataproviders/subreports. When we have a report fetching data from multiple sources, the paralel processing could improve the report performance too. Is serial query execution type a tool feature? Is there any reason behind not designing a tool with paralel query execution option.
    Thanks
    Aravind

    Hi Aravind,
    The logic of the reports do not allow paralel SQL being sent. Work down the page, intial database is queried to get the data for the main report, once the data is retrieved then CR starts to process it starting at the Report header and working it's way down. When the process gets to a section where a subreport is found it then takes the linking parameter and passes that to the subreport and then send off the query to the database. It will do this each time a new value is passed to the subreport.
    So logically if the first SQL is not run the values for the subreports cannot be generated. Unless you return all records but that would not be efficient either.
    To optimize your report create a Stored Proced which runs Server side and return one data set to the Designer. Servers are much more efficient at optimize data collection than our various tools are.
    Thank you

  • ABAP query processing in bgrnd and saving file to prsntn/application server

    Hello Gurus
    I have question regarding to ABAP query execution. Currently I try to find out if ABAP query can be executed in background and store the result into UNIX directory or in the presentation server(desktop). What I found is that the report need to be executed using option Private File and the data by default will be stored at directory /sap/outbound/.
    However what I found next is that the maximum fields should be 64 fields. If the query result has more than 64 fields, the error will occurs WRITE_TO_OFFSET_TOOLARGE.
    My question is:
    1. Can we set the directory in unix folder to someplace else than /sap/outbound/ ?
    2. Can we set in order to have the report stored without limitation 64 fields?
    Thanks in advance

    HI
    Yes you can set the directory in unix folder to someplace as you need to get confirmation for the path from your Functional Analyst.
    Thanks

  • Parllel query processing

    I have created the aggregates monthly wise to cube.If i execute the report using rsrt, and if i given the selection for 3 months( ex: 04.2007 to 06.2007) then it is not hitting any aggregates.
    But if i give the selction for only month ( like only 4, or 5 or ,6 ) then it is hitting particular month aggregate.
    Could you advise how to resolve this.
    Thanks in advance.

    Could you explain little bit elaobrate regarding this.
    In my case we have quaterly cubes, for every cube i have created monthly wise
    aggregates.When i execute the report (using RSRT) , in the selections i have given
    04.2007 to 06.2007, now it is not hitting aggregates,directly getting data from CUBE.
    But you are saying is Aggregate Parllel processing is not possible, but it should hit
    should 4 th , 5 th  and 6 th month aggregate in sequentially..
    Am i correct??? .It is not happening.
    Thanks

  • Parallel query processing. (Max Processors)

    Hi Guys,
    We have a System running on SQL 2000, and it configured to use all available processors.
    (Server properties>Processor)
    I am about to change it to use 1 processor as per microsoft recommendation, but there another option when you select fixed number of processor instead of all available processors, which is
    "Minimum query plan threshold for considering queries for parallel execution(cost estimate)"
    http://picasaweb.google.com/lh/photo/8N0-WQt3m23vEiupxdjtwQ?feat=directlink
    can anybody suggest me, how do you estimate this number. or you guys can post what is current threshold value in your SQL 2000 server environment. (I dont see this option in SQL 2005,probably its handled automatically).
    Thanks Guys

    Hi Fan Yu
    SAP on Microsoft SQL Server
    In the above document, page 44 under section Max degree of parallesim, microsoft recommends this value to be set to 1.
    (Reasons are discussed in the white paper)
    Like i said, SQL 2000 has one more option regarding max degree of parallelism, i.e "Minimum query plan threshold for considering queries for parallel execution(cost estimate)" 
    http://picasaweb.google.com/lh/photo/8N0-WQt3m23vEiupxdjtwQ?feat=directlink
    Probably i was not clear in my question, this is not related to number of processors and data files, but number of processors used by the query engine at a given  time.(max degree of parallelism).
