Performance issue with using MAX function in pl/sql

Hello All,
We are having a performance issue with the below logic wherein MAX is being used in order to get the latest instance/record for a given input variable ( p_in_header_id).. the item_key is having the format as :
p_in_header_id - <number generated from a sequence>
This query to fetch even 1 record takes around 1 minutes 30 sec..could someone please help if there is a better way to form this logic & to improve performance in this case.
We want to get the latest record for the item_key ( this we are getting using MAX (begin_date)) for a given p_in_header_id value.
Query 1 :
SELECT item_key FROM wf_items WHERE item_type = 'xxxxzzzz'
AND SUBSTR (item_key, 1, INSTR (item_key, '-') - 1) =p_in_header_id
AND root_activity ='START_REQUESTS'
AND begin_date =
(SELECT MAX (begin_date) FROM wf_items WHERE item_type = 'xxxxzzzz'
AND root_activity ='START_REQUESTS'
AND SUBSTR (item_key, 1, INSTR (item_key, '-') - 1) =p_in_header_id);
Could someone please help us with this performance issue..we are really stuck because of this
regards

First of all Thanks to all gentlemen who replied ..many thanks ...
Tried the ROW_NUMBER() option but still it is taking time...have given output for the query and tkprof results as well. Even when it doesn't fetch any record ( this is a valid cased because the input header id doesn't have any workflow request submitted & hence no entry in the wf_items table)..then also see the time it has taken.
Looked at the RANK & DENSE_RANK options which were suggested..but it is still taking time..
Any further suggestions or ideas as to how this could be resolved..
SELECT 'Y', 'Y', ITEM_KEY
FROM
( SELECT ITEM_KEY, ROW_NUMBER() OVER(ORDER BY BEGIN_DATE DESC) RN FROM
WF_ITEMS WHERE ITEM_TYPE = 'xxxxzzzz' AND ROOT_ACTIVITY = 'START_REQUESTS'
AND SUBSTR(ITEM_KEY,1,INSTR(ITEM_KEY,'-') - 1) = :B1
) T WHERE RN <= 1

  • Performance issues with pipelined table functions

    I am testing pipelined table functions to be able to re-use the <font face="courier">base_query</font> function. Contrary to my understanding, the <font face="courier">with_pipeline</font> procedure runs 6 time slower than the legacy <font face="courier">no_pipeline</font> procedure. Am I missing something? The <font face="courier">processor</font> function is from [url http://www.oracle-developer.net/display.php?id=429]improving performance with pipelined table functions .
    Edit: The underlying query returns 500,000 rows in about 3 minutes. So there are are no performance issues with the query itself.
    Many thanks in advance.

    Like:

  • Performance issue with using buffering in a APPL0 or APPL1 Table

    Hi,
    Can anyone please tell me whether there's any serious performace issue with using buffering for a Master or Transaction table? I'm asking this because when I run code inspector for my transp table I'm getting information message:
    Message Code 0011 ==> Buffereing is Activated but Delivery Class Is "A" and Message Code 0014 ==> Buffereing is Activated but Data Class Is "APPL1".
    So what's other way round for improving performance.
    Thanks,
    Mahesh M.S.

    Hi,
    have you read the documentation?
    Let me paste it here for you:
    Buffering is switched on for the examined table and it has data type 'APPL0' or 'APPL1'.
    Tables with data type 'APPL0' or 'APPL1' should contain master or transaction data, so these tables should either contain a large amount of data or their content should change frequently. Therefore buffering the table is unfavourable. Very large tables suppress other tables in the buffer memory and hence slow done any access to them. Transaction data should not be buffered because the synchronization of the changes on the various application servers is very time consuming.
    In exceptional cases, small master data tables ('APPL0', size category 0) can be buffered.
    The solution depends on the table content. If it is master or transaction data, the table should not be buffered. If the table content does not consist of master or transaction data, the data type should be corrected accordingly.
    This should answer your questions...
    Kind regards,
    Hermann

  • Issue with use of Function Module GUI_UPLOAD

    Hi Experts,
    I have an issue in using the Function Module GUI_UPLOAD for uploading the contents of an Excel file on the Presentation Server to an internal table in an ABAP Program.
    My file consists of around 300 records but the FM succeeds in uploading only the first 6 lines to the Internal Table specified while calling the FM.
    I dont have any idea why this happens. Any pointers in this direction will be helpful.

  • Performance issue with using out parameter sys_refcursor

    Hello,
    I'm using Oracle 10g, with ODP.Net in a C# application.
    I'm using about 10 stored procedures, each having one out parameter of sys_refcursor type. when I use one function in C# and call these 10 sp's, it takes about 78ms to excute the function.
    Now to improve the performance, I created one SP with 10 output parameters of sys_refcursor type. and i just call this one sp. the time taken has increased , not it takes abt 95ms.
    is this the right approach or how can we improve the performance by using sys_refcursor.
    please suggest, it is urgent, i'm stuck up with this issue.
    thanks
    shruti

    With 78ms and 95ms are you talking about milliseconds or minutes? If it's milliseconds then what's the problem and does it really matter if there is a difference of 17 milliseconds as that could just be caused by network traffic or something. If you're talking minutes, then we would need more information about what you are attempting to do, what tables and processing is going on, what indexes you have etc.
    Query optimisation tips can be found on this thread.. When your query takes too long ....
    Without more information we can't really tell what's happening.

  • Performance problems with use SCOPE instruction?

    Hi All!
    We have application work with cube bases on SSAS 2008 R2. Also we use writeback function for change data in cube.
    Now I'm looking bottleneck in our queries.
    We have following MDX query(for example):
    select
    non empty{
    ([Date].[Date].[All].children
    , [Forecast Type].[Forecast Type].[All].children

    Duration execution this query(Query end):
    cold(after clear cache) - 1000
    warm - 500
    Max loss on Calculate Non empty event - 95%.
    After some operations I found bottleneck in 2 measures: [Measures].[Weight], [Measures].[Price CR]
    If them deleted from query then duration execution equals 50.
    In our cube measure [Measures].[Weight] override in calculation as: 
    scope([Measures].[Weight]);
    This = iif((round([Measures].[Weight], 3)<>0), round([Measures].[Weight], 3), null);
    end scope;
    But if I change code as 
    scope([Measures].[Weight]);
    This = [Measures].[Weight];
    end scope;
    Performance query does not improve...
    If delete this override from calculation in cube. I get good performance acceptable to me.
    We need to keep the business logic and get acceptable performance.
    What wrong in measures, calculations or query? Any ideas?
    If need additional information let me know.
    Many thanks, Dmitry.

    Hi Makarov,
    According to your description, you get performance issue when using SCOPE() statement. Right?
    In Analysis Services, when using SCOPE() statement, it redefines that part of your cube space while the calculated member is much more isolated. In this scenario, I suggest you directly create a measure. Because calculated measure only returns values
    where the amounts are recorded directly to the parent without including children values.

  • Performance Issues with Folio format in Ipad.

    Hello everyone! My FIRST post here!!!
    I work with educational games and I'm facing performance issues with games that I've made in HTML5 to play in Ipad. I tried to import them to the format folio in DPS (Adobe Digital Publishing Suite). However when I import the HTML game into Indesign and try to preview it in Adobe content viewer, the game doesn't open or works without perform properly (there is a lag that doesn't let you play the game with a little of fun).
    The games that I've created have a memory use max of 35mb and weighs 30mb max.
    Does anyone know what's happen and what I can do to fix that performance issue?
    Thanks a lot!

  • Performance issues with FDK in large XML documents

    In my current project with FrameMaker 8 I'm experiencing severe performance issues with some FDK API calls.
    The documents are about 3-8 MBytes in size. Fortmatted they cover 150-250 pages.
    When importing such an XML document I do some extensive "post-processing" using FDK. This processing happens in Sr_EventHandler() during the SR_EVT_END_READER event. I noticed that some FDK functions calls which modify the document's structure, like F_ApiSetAttribute() or F_ApiNewElementInHierarchy(), take several seconds, for the larger documents even minutes, to complete one single function call. I tried to move some of these calls to earlier events, mostly to SR_EVT_END_ELEM. There the calls work without a delay. Unfortunately I can't rewrite the FDK client to move all the calls that are lagging to earlier events.
    Does anybody have a clue why such delays happen, and possibly can make a suggestion, how to solve this issue? Thank you in advance.
    PS: I already thought of splitting such a document in smaller pieces by using the FrameMaker book function. But I don't think, the structure of the documents will permit such an automatic split, and it definitely isn't an option to change the document structure (the project is about migrating documents from Interleaf to XML with the constraint of keeping the document layout identical).

    FP_ApplyFormatRules sounds really good--I'll give it a try on Monday. Wonder how I could miss it, as I already tried FP_Reformatting and FP_Displaying at no avail?! By the way, what is actually meant with FP_Reformatting (when I used it I assumed it would do exactly what FP_ApplyFormatRules sounds to do), or is that one another of Lynne's well-kept secrets?
    Thank's for all the helpful suggestions, guys. On Friday I already had my first improvements in a test version of my client: I did some (not all necessary) structural changes using XSLT pre-processing, and processing went down from 8 hours(!) to 1 hour--Yeappie! I was also playing with the idea of writing a wrapper to F_ApiNewElementInHierarchy() which actually pastes an appropriate element created in a small flow on the reference pages at the intended insertion location. But now, with FP_ApplyFormatRules on the horizon, I'm quite confident to get even the complicated stuff under control, which cannot be handled by the XSLT pre-processing, as it is based on the actual formatting of the document at run-time and cannot be anticipated in pre-processing.

    AND SAWITH6.c2 >= SAWITH3.c2
    The SAWITH3 and SAWITH6 dimensions using time series fuctions are causing a full table scan on W_GL_BALANCE_F and W_GL_ACCOUNT_D . Though we are interested in just getting 2009/11 data; the queries generated by time series function TODATE is taking us against entire W_DAY_D data and is causing several performance issues.
    W_GL_BALANCE_F table has index on GL_ACCOUNT_WID and BALANCE_DT_WID.
    How can we force to use index on these columns for better performance.
    Please advise us on the right approach to improve performance.

    Thanks
    Srini Pendem

    Hi Srini,
    I've had quite a bit of performance issues with ToDate and Ago. I tended to create materialized views on my fact tables that would materialize those values as columns and that way I would avoid having to use the ToDate or Ago functions. Is there any chance you can implement a similar solution and bypass the time series functions entirely?
    Just to check, those tables belong to BI Apps, right? If so, you can log an SR about the performance issue since it's an issue with the model that Oracle sold you.
    Good luck!

  • Performance issue with a Custom view

    Hi ,
    I am pretty new to performance tuning and facing a performance issue with a custom view.
    Execution time for view query is good but as soon as I append a where caluse to view query ,the execution time increases.
    Below is the view query:
    CREATE OR REPLACE XXX_INFO_VIEW AS
    SELECT csb.system_id license_id,
    cst.name license_number ,
    csb.system_type_code license_type ,
    csb.attribute3 lac , -- license authorization code
    csb.attribute6 lat , -- license admin token
    csb.attribute12 ols_reg, -- OLS Registration allowed flag
    l.attribute4 license_biz_type ,
    NVL (( SELECT 'Y' l_supp_flag
    FROM csi_item_instances cii,
    okc_k_lines_b a,
    okc_k_items c
    WHERE c.cle_id = a.id
    AND a.lse_id = 9
    AND c.jtot_object1_code = 'OKX_CUSTPROD'
    AND c.object1_id1 = cii.instance_id||''
    AND cii.instance_status_id IN (3, 510)
    AND cii.system_id = csb.system_id
    AND a.sts_code IN ('SIGNED', 'ACTIVE')
    AND NVL (a.date_terminated, a.end_date) > SYSDATE
    AND ROWNUM < 2), 'N') active_supp_flag,
    hp.party_name "Customer_Name" , -- Customer Name
    hca.attribute12 FGE_FLAG,
    (SELECT /*+INDEX (oklt OKC_K_LINES_TL_U1) */
    nvl(max((decode(name, 'eSupport','2','Enterprise','1','Standard','1','TERM RTU','0','TERM RTS','0','Notfound'))),0) covName --TERM RTU and TERM RTS added as per Vijaya's suggestion APR302013
    FROM OKC_K_LINES_B oklb1,
    OKC_K_LINES_TL oklt,
    OKC_K_LINES_B oklb2,
    OKC_K_ITEMS oki,
    CSI_item_instances cii
    WHERE
    OKI.JTOT_OBJECT1_CODE = 'OKX_CUSTPROD'
    AND oklb1.id=oklt.id
    AND OKI.OBJECT1_ID1 =cii.instance_id||''
    AND Oklb1.lse_id=2
    AND oklb1.dnz_chr_id=oklb2.dnz_chr_id
    AND oklb2.lse_id=9
    AND oki.CLE_ID=oklb2.id
    AND cii.system_id=csb.system_id
    AND oklt.LANGUAGE=USERENV ('LANG')) COVERAGE_TYPE
    FROM csi_systems_b csb ,
    csi_systems_tl cst ,
    hz_cust_accounts hca,
    hz_parties hp,
    fnd_lookup_values l
    WHERE csb.system_type_code = l.lookup_code (+)
    AND csb.system_id = cst.system_id
    AND hca.cust_account_id =csb.customer_id
    AND hca.party_id= hp.party_id
    AND cst.language = USERENV ('LANG')
    AND l.lookup_type (+) = 'CSI_SYSTEM_TYPE'
    AND l.language (+) = USERENV ('LANG')
    AND NVL (csb.end_date_active, SYSDATE+1) > SYSDATE)
    I have forced an index to avoid Full table scan on OKC_K_LINES_TL and suppressed an index on CSI_item_instances.instance id to make the view query fast.
    So when i do select * from XXX_INFO_VIEWit executes in a decent time,But when I try to do
    select * from XXX_INFO_VIEW where active_supp_flag='Y' and coverage_type='1'
    it takes lot of time.

    Hi,
    You should always try using primary index fields, if not possible then secondary index fields.
    Even if you cannot do anything from either of the two then try this,
    Use Less distinct fields on the top.
    In your case , you can use bukrs ,gjahr ,werks on the top in the where condition..then followed by less distinct values..
    Even when you use secondary index if you have 4 fields in your sec index and you are using only two fields from the top then the index is useful only upto that two fields provided they are in sequence.

  • Performance issues with Homesharing?

    I have a Time Capsule as the base station for my wireless network, then 2 Airport Express setup to extend the network around the house, an iMac i7 as the main iTunes Library and couple of iPads, and a couple of Apple TVs. Everything has the latest software, but I have several performance issues with Home sharing. I've done several tests making sure nothing is taking additional bandwidth, so here are the list of issues:
    1) With nothing else running, trying playing a movie via home sharing in an iPad 2 which is located on my iMac, it stops and I have to keep pressing the play button over and over again. I typically see that the iPad tries to download part of the movie first and then starts playing so that it deals with the bandwidth, but in many cases it doesn't.
    2) When trying to play any iTunes content (movies, music, photos, etc) from my Apple TV I can see my computer library, but when I go in on any of the menus, it says there's no content. I have to reboot the Apple TV and then problem fixed. I's just annoying that I have to reboot.
    3) When watching a Netflix movie on my iPad and with Airplay I send the sound to some speakers via Airplay through an Airport Express. At time I lose the connection to the speakers.
    I've complained about Wifi's instability, but here I tried to keep everything with Apples products to avoid any compatibility issues and stay within N wireless technology, which I understood it was much more stable.
    Has anyone some suggestions?

    Hi,
    you should analyze the db after you have loaded the tables.
    Do you use sequences to generate PKs? Do you have a lot of indexex and/or triggers on the tables?
    If yes:
    make sure your sequence caches (alter sequence s cache 10000)
    Drop all unneeded indexes while loading and disable trigger if possible.
    How big is your Redo Log Buffer? When loading a large amount of data it may be an option to enlarge this buffer.
    Do you have more then one DBWR Process? Writing parallel can speed up things when a checkpoint is needed.
    Is it possible using a direct load? Or do you already direct load?

  • Performance Issues with large XML (1-1.5MB) files

    Hi,
    I'm using an XML Schema based Object relational storage for my XML documents which are typically 1-1.5 MB in size and having serious performance issues with XPath Query.
    When I do XPath query against an element of SQLType varchar2, I get a good performance. But when I do a similar XPath query against an element of SQLType Collection (Varray of varchar2), I get a very ordinary performance.
    I have also created indexes on extract() and analyzed my XMLType table and indexes, but I have no performance gain. Also, I have tried all sorts of storage options available for Collections ie. Varray's, Nested Tables, IOT's, LOB's, Inline, etc... and all these gave me same bad performance.
    I even tried creating XMLType views based on XPath queries but the performance didn't improve much.
    I guess I'm running out of options and patience as well.;)
    I would appreciate any ideas/suggestions, please help.....
    Thanks;
    Ramakrishna Chinta
