Performance tuning

Hi guys!
I'll be always in favour to you if u could really help me this out.The program displays all the Sales order(RMA's) who's series starts with number 6 in our company ie for Return Manufacturing Authoriazation.What ever the orders which are returned back has a return reason text of more than 600 char long(for this i'm using FM read_text).The problem here is the we have around 6 fields in the selection screen and the end user only enters three fields ie Plant Org,Document Type(only two values ZORE and ZSRE) and the sales order creation date range.Now when i give a date range of four months it is taking 9 minutes to display the data.And the end user wants the date range of one year.When i give the range for 1 year it is running out of time and displays a runtime erro.Please find the solution for this to improve the performance.For your refrence i'm attaching my coding.Its really urgent.........................Please help..............................

  • Report running for long time & performance tuning

    Hi All,
    (1). WebI report is running for long time.so what are the steps i need to check for it ?
    (2). Can you tell me about performance tuning in BO ?
    please help me.....
    Thanks
    Kumar

    (1). WebI report is running for long time.so what are the steps i need to check for it ?
    The first step is to see if the problem lies in the query on the data source or in webi itself. Depending on the data source there are different ways to extract the query and try to run it against the database. Which source does your report uses?
    (2). Can you tell me about performance tuning in BO ?
    I would recommend to start by reading the administrator's guide. There is a section about how to improve performance.

  • Oracle  11g Performance tuning approach ?

    Hello Experts,
    Is it the right forum to follow oracle performance tuning discussions ? If not, let me know what will be the forum to pick up some thread on this subject.
    I am looking for performance tuning approach for oracle 11g. I learned there are some new items in 11g in this regard. For persons, who did tuning in earlier versions of Oracle,
    what will be the best way adopt to 11 g?
    I reviewed the 11g performance tuning guide, but I am looking for some white papers/blogs with case studies and practical approaches. I hope that you have used them.
    What are the other sources to pick up some discussions?
    Do you mind, share your thoughts?
    Thanks in advance.

    The best sources of information on performance tuning are:

  • Performance tuning of BPEL processes in SOA Suite 11g

    Hi,
      We are working with a customer for performance tuning of SOA Suite 11g, one of the areas is to tune the BPEL processes. I am new to this and started out with stress testing Hello World process using SOAPUI tool. I would like help with the below topics -
    1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
    2. Do we need to run stress tests for every BPEL process deployed?
    2. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
    Thanks in advance!
    Sritama

    1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
    You need
    pay attention to:
    java heap usage vs java heap capacity
    java eden usage vs java eden capacity
    JDBC pool initial connections vs JDBC pool capacity connections
    if you are using linux: top
    if you are using aix: topas
    2. Do we need to run stress tests for every BPEL process deployed?
    yes, you need test each BPEL. You can use "Jmeter" tool.
    Download Jmeter from here: Apache JMeter - Apache JMeter&amp;trade;
    Other tools:
    jstat
    jstack
    jps -v
    Enterprise Manager
    WebLogic Console
    VisualVM
    JRockit Mission Control
    3. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
    I recommend "Oracle SOA Suite 11g Performance Tuning Cookbook" http://www.amazon.com/Oracle-Suite-Performance-Tuning-Cookbook/dp/1849688842/ref=sr_1_1?ie=UTF8&qid=1378482031&sr=8-1&keywords=oracle+soa+suite+11g+performance+tuning+cookbook

  • [ADF-11.1.2] Proof of view performance tuning in oracle adf

    Hello,
    Take an example of : http://www.gebs.ro/blog/oracle/adf-view-object-performance-tuning-analysis/
    It tells me perfectly how to tune VO to achieve performance, but how to see it working ?
    For example: I Set Fetch size of 25, 'in Batch of' set to 1 or 26 I see following SQL Statement in Log
    [1028] SELECT Company.COMPANY_ID,         Company.CREATED_DATE,         Company.CREATED_BY,         Company.LAST_MODIFY_DATE,         Company.LAST_MODIFY_BY,         Company.NAME FROM COMPANY Companyas if it is fetching all the records from table at a time no matter what's the size of Batch. If I am seeing 50 records on UI at a time, then I would expect at least 2 SELECT statement fetching 26 records by each statement if I set Batch Size to 26... OR at least 50 SELECT statement for Batch size set to '1'.
    Please tell me how to see view performance tuning working ? How one can say that setting batch size = '1' is bad for performance?

    Anandsagar,
    why don't you just read up on http://download.oracle.com/docs/cd/E21764_01/core.1111/e10108/adf.htm#CIHHGADG
    there are more factors influencing performance than just query. Btw, indexing your queries also helps to tune performance

  • Performance tuning in PL/SQL code

    Hi,
    I am working on already existing PL/SQL code which is written by someone else on validation and conversion of data from a temporary table to base table. It usually has 3.5 million rows. and the procedure takes arount 2.5 - 3 hrs to complete.
    Can I enhance the PL/SQL code for better performance ? or, is this OK to take so long to process these many rows?
    Thanks!
    Yogini

    Can I enhance the PL/SQL code for better performance ? Probably you can enhance it.
    or, is this OK to take so long to process these many rows? It should take a few minutes, not several hours.
    But please provide some more details like your database version etc.
    I suggest to TRACE the session that executes the PL/SQL code, with WAIT events, so you'll see where and on what time is spent, you'll identify your 'problem statements very quickly' (after you or your DBA have TKPROF'ed the trace file).
    SQL> alter session set events '10046 trace name context forever, level 12';
    SQL> execute your PL/SQL code here
    SQL> exitWill give you a .trc file in your udump directory on the server.
    http://www.oracle-base.com/articles/10g/SQLTrace10046TrcsessAndTkprof10g.php
    Also this informative thread can give you more ideas:
    HOW TO: Post a SQL statement tuning request - template posting
    as well as doing a search on 10046 at AskTom, http://asktom.oracle.com will give you more examples.

  • Performance tuning in EP6 SP14

    Hi,
    We just migrated our development EP5 SP6 portal to NW04 EP6 SP14 and are seeing some performance problems with a limited number of users (about 3). 
    Please point me to some good clear documentation related to performance tuning.  Better yet, please tell me some things you have done in your EP6 portal to improve performance.
    Any help is greatly appreciated.
    Regards,
    Rick

    Hi
    In general we have experienced that NW04 is faster than earlier versions.
    One of the big questions is if the response time is SERVER time (used for processing on the J2EE server), NETWORK time (latency and many roundtrips), CLIENT time (rendering, virus-scanning etc) or a combination.
    1) Is the capacity on the server ok?  CPU utilization and queue lenght high?  Memory swapping?
    2) A quick optimazation server-side is logging: Plese verify that that log and trace levels are ERROR /FATAL or NONE on J2EE and also avoid logging on IIS and IIS proxy is used
    3) Using a HTTP trace you can see if the NW portal for some reason generetes more roundtrips (more GETS) that the old portal for the same content - what is the network latency?  Try to do a "ping <server>" from a client pc and see the time (latency) - if it is below 20 ms the network should do a big difference.
    4) On the client try to call the portal with anti-virus de-activated if the delta/difference in response times are HUGE your client could be to old? (don't underestimate the client). Maybee the compression should be set different to avoid compres (server) and uncompres (client) - this is a tradeoff with network latency however.
    Also client-side caching (in browser) is important.
    These are just QUICK point to consider - tuning is complex

  • Performance Tuning in IR

    Hello All,
    We have created some reports using Interactive Reporting Studio. The volume of data in that Oracle database are huge and in some tables of the relational database are having above 3-4 crores rows individually. We have created the .oce connection file using the 'Oracle Net' option. Oracle client ver is 10g. We earlier created pivot, chart and report in those .bqy files but had to delete those where-ever possible to decrease the processing time for getting those report generated.
    But deleting those from the file and retaining just the result section (the bare minimum part of the file) even not yet helped us out solving the performance issue fully. Still now, in some reports, system gives error message 'Out of Memory' at the time of processing those reports. The memory of the client PCs,wherefrom the reports are being generated are 1 - 1.5 GB. For some reports, even it takes 1-2 hours for saving the results after process. In some cases, the PCs gets hanged at the time of processing. When we extract the query of those reports in sql and run them in TOAD/SQL PLUS, they take not so much time like IR.
    Would you please help us out in the aforesaid issue ASAP? Please share your views/tips/suggestions etc in respect of performance tuning for IR. All reply would be highly appreciated.
    Regards,
    Raj

    SQL + & Toad are tools that send SQL and spool results; IR is a tool that sends a request to the database to run SQL and then fiddles with the results before the user is even told data has been received. You need to minimize the time spent by IR manipulating results into objects the user isn't even asking for.
    When a request is made to the database, Hyperion will wait until all of the results have been received. Once ALL of the results have been received, then IR will make multiple passes to apply sorts, filters and computed items existing in the results section. For some unknown reason, those three steps are performed more inefficiently then they would be performed in a table section. Only after all of the computed items have been calculated, all filters applied and all sorts sorted, then IR will start to calculate any reports, charts and pivots. After all that is done, the report stops processing and the data has been "returned"
    To increase performance, you need to fine tune your IR Services and your BQY docs. Replicate your DAS on your server - it can only transfer 2g before it dies, restarts and your requested document hangs. You can replicated the DAS multiple times and should do so to make sure there are enough resources available for any concurrent users to make necessary requests and have data delivered to them.
    To tune your bqy documents...
    1) Your Results section MUST be free of any sorts, filters, or computed items. Create a staging table and put any sorts or local filters there. Move as many of your computed items to your database request line and ask the database to make the calculation (either directly or through stored procedures) so you are not at the mercy of the client machine. Any computed items that cannot be moved to the request line, need to be put on your new staging table.
    2) Ask the users to choose filters. Programmatically build dynamic filters based on what the user is looking for. The goal is to cast a net only as big as the user needs so you are not bringing back unnecessary data. Otherwise, you will bring your server and client machines to a grinding halt.
    3) Halt any report pagination. Built your reports from their own tables and put a dummy filter on the table that forces 0 rows in the table until the report is invoked. Hyperion will paginate every report BEFORE it even tells the user it has results so this will prevent the user from waiting an hour while 1000s of pages are paginated across multiple reports
    4) Halt any object rendering until request. Same as above - create a system programmically for the user to tell the bqy what they want so they are not waiting forever for a pivot and 2 reports to compile and paginate when they want just a chart.
    5) Saved compressed documents
    6) Unless this document can be run as a job, there should be NO results stored with the document but if you do save results with the document, store the calculations too so you at least don't have to wait for them to pass again.
    7) Remove all duplicate images and keep the image file size small.
    Hope this helps!
    PS: I forgot to mention - aside from results sections, in documents where the results are NOT saved, additional table sections take up very, very, very small bits of file size and, as long as there are not excessively larger images the same is true for Reports, Pivots and Charts. Additionally, the impact of file size only matters when the user is requesting the document. The file size is never an issue when the user is processing the report because it has already been delivered to them and cached (in workspace and in the web client)
