  • Report Variable F4 help performance issue

    Hi,
    I have a BI report on DSO >> Multiprovider.
    When i choose F4 Variable help it takes around 2-3 minutes to display the data for selection.
    Currently XXXX chars is with -- Only Posted Values for Navigation. I have tried the below options but could not see any improvement in variable f4 help performance.
    -- Only Values in Infoprovider
    -- Values In Master Data table
    Could someone please suggest if you have faced the similar issue.
    Thanks
    Ashok

    Hello Ashok,
    Ideally you should never built a report based on a DSO, this is because it stores data at a line item level. The way the filter works is that looks at all records (SIDs) lying in the range of selection in the info provider and then displays the filter pane after it populates the records.
    There can only be 1 check in this case, is to check if your DB statistics are up-to-date. The DB statistics decide if an index is to be used or not. So check for the DSO active table and all related SID tables in transaction DB20. Check the date of creation of the statistics, if it's too much in the past, then the DB does not effectively use the indices and hence it takes time.
    You can use program RSANAORA to recompute the statistics.

  • Does DB compact help performance

    We have DB where there have been heavy create/delete and read traffic. The DB XML stores around 1.4 million xml documents around 4/8k in size.
    The DB XML file has grown to be around 24 gigs.
    I understand this is a DB forum but the question seems generic.. given that the DB is a sparse file.. does DB compacting help performance?
    We are seeing latency times raise up quite high periodically (potentially correlated with checkpointing).
    What kind of information should we collect from the running environment to help deduct the impact of checkpointing on such a DB file?

    Using DB->compact can help the performance of any database that has been heavily updated. It will attempt to move data to a smaller number of pages in the database. This will make database page cache more efficient. DB->compact may be run while other activities are happening in the database but it is a heavy weight operation, reading all of the database and updating many pages, so it is recommended that it be used at a time when you have less other activity.
    A checkpoint will schedule all dirty pages in the cache to be written to disk. This can certainly slow things down if you have many dirty pages. Using the utility db_stat -m will show you the activity in the page cache. It does not directly show you the impact of a checkpoint but will tell you how many pages have been written to disk. You can use db_stat -mZ to reset the statistics prior to a checkpoint to see more clearly what happens during the checkpoint.
    To spread out the effect of the checkpoint you can run a trickle thread (see http://www.oracle.com/technology/documentation/berkeley-db/db/api_c/memp_trickle.html ) which will write pages to disk between checkpoints.

  • Does adding RAM really help performance?

    My iMac 1.8 GHz G5 is about two years old and starting to run slowly. Could it be the 10,000 photos and 6,000 songs? I've started using my MacBook for most work and my iMac for most play (i.e. media).
    Does adding RAM really help performance? I've only got one 512 MB chip.
    Thanks for any help.

    Hello,
    Yes, adding more memory can make a huge performance improvement.
    I've owned two iMac G5 systems. And, in both cases, I noticed a huge performance improvement jumping to 1 GB of RAM. And, while not huge, I noticed even better performance going from 1 GB to 2 GB of RAM.
    512 MB is minimal, and adequate. But, more memory makes OS X run considerably better.
    I hope this helps.

  • Please help - performance issues with Lr 2.3

    I really hope some user/s or Adobe support members could help me with tweaks/suggestions to improve Lightroom 2.3's sluggish performance on my computer.
    First of all I have read about 100 different forum topics this morning, have used the forum search extensively and I cannot find any one topic which talks about different methods for improving performance. So I really have tried to find the answer before asking for help and I have done a lot of googling to try and find some simple answers but after all this reading I am more confused than when I started out.
    Let me first explain what I am experiencing and I will try and be as detailed as possible.
    1 - When I browse the library it is incredibly slow rendering the thumbnail previews. I found a topic which talked about degfragging the LR catalog using sqlite and contig, I did that and it made no difference to performance.
    2 - I left my machine running an entire day to render the 1:1 previews thinking this would help me with the slow thumbnail issues but it made no difference. It is however faster now when I double click and image and get the immediate 1:1 preview :)
    3 - I have turned off the Automatically write changes into XMP, suggested on another topic, that made no noticeable differences to performance either.
    4 - A few months ago when I was still running 2.1 I found a topic either here or on Google that told me to delete the entire previews folders and let LR recreate them from scratch, I did that back then and that did not make any difference either, turned out to be 24 hours of waste time for me.
    5 - I tried changing the following settings under catalog settings (has not improved anything):
    size: 2048 Pixels
    quality: High
    automatically discard 1:1 previews: Never
    6 - The only slow performance I am experiencing in LR is the thumbnails and this slows down my workflow dramatically. Everything else in LR seems to be quite fluid and usable and fast. I notice many users have complained about the slow thumbnails issues and I was praying that 2.3 was going to sort this out.
    7 - I have also noticed that when scrolling up and down the thumnail list it sometimes uses more than 1 processing core and then sometimes not and then when I stop scrolling up and down the thumbnails and leave it alone for 5 seconds suddenly all 8 processing cores spike to around 50% usage with processing "something".
    8 - I have tried making my thumbnail previews different sizes, also makes no difference really, unless I go to the smallest size and then it seems ok but then it's hard to see what's going on at all with thumbnails that small.
    9 - Lightroom is only using up 1.1 GB of available memory so I do no think the slowness relates to memory and I am running my memory in a proper DDR3 configuration.
    10 - I have tried playing with my graphics card settings (below) but it does not seem to help no matter what I try.
    11 - Overall it "seems" that Lightroom is trying to re-render thumbnails continously, I know technically this may not be true but as an end user this is how it feels to me.
    My computer specifications are as follows:
    Intel i7 965 Extreme Edition (not overclocked)
    Intel DX58 Smackover Motherboard
    6GB DDR3 Ram (not overclocked)
    GEForce 9800GT Video Card (with WHQL driver)
    SATA 2 1TB Seagate Drives
    Windows Vista X64 (SP1)
    Lightroom 2.3 X64
    NEC 30" Display running at 2560x1600 resolution
    The way I have LR configured on my PC is as follows:
    - Program files installed on main C drive which is a 250GB partition on a 1TB Seagate Sata 2 drive with 190 GB Free space all the time.
    - Lightroom catalog is on my E drive which is a 1TB Seagate Sata 2 drive
    - Camera Raw Cache is set at 10GB and resides on the same E drive as the LR catalog
    - My E drive has 100GB Free Space
    - I have tried tweaks to the video card settings to be Lightroom spe

    Hi Don
    Thanks for the reply, I have tried changing any/all settings on the card set to performance versus quality and still it has no effect. I just got the latest video driver for the GT9800 which was released on the 3rd of March and that has no effect either. I tried loading the 32 bit version of Lightroom without any improvement to speed on the thumbnails whatsoever so that rules out the possibility of it being something to do with 64-bit.
    I read an Adobe knowledgebase article saying that the Nvidia control panel conflicts with certain Adobe software but they do not say how to turn it off and I also cannot even find the answer to that on Nvidia's forums either. So I still cannot say whether or not the Nvidia control panel is the problem because I cannot disable it.
    I phoned a friend this morning who is running Lightroom 2.3 on a simple Core-2 Duo machine and his thumbnails render in half the time that mine do and my hardware is top of the range stuff in comparison so you can imagine my frustration with this thumbnailing issue. My friend also has an Nvidia card 8800GT I think.
    I have spent so much time on this and I am no further to a solution and this blurry thumbnail issue is seriously messing with my eyes and it does not make for a very pleasant user experience.
    What concerns me is that while Lightroom is idle and the machine is idle Lightroom is not doing anything in the background like rendering thumbnails. It only starts rendering them once I scroll down a page, no doubt by design but for more powerful machines there is a lot of processing ability going unused. The thumbnails on the filmstrip render a lot faster compared to grid view but their rendering state is also not retained and once I have scrolled past 100 images and then scroll back they are all blurry again and I have to wait for them re-render all over again. All this re-rendering of thumbs is a really big waste of time.
    I also noticed something else interesting this morning, I opened task manager and left it open while I was scrolling thumbnails (continuous scrolling without waiting for them to render sharp) and only one core was being used to do this processing, I tested this multiple times and left it open while I scrolled through 5000+ images and only one core the whole time was being used. Only once I stopped scrolling and Lightroom began it's rendering of the thumbnails (about 10-15 seconds after stopping scrolling) did it only then start using multiple processors, I'm not sure if that has something to do with anything and memory wise I have 4.2 GB of available memory and Lightroom is only using about 425 Mb of memory.
    I have changed the size of my thumbnails to below halfway on the slider and that made only a slight difference, although now they are so small on this 30" screen that I am now suffering even more eye strain as a result.
    I am busy loading LR 1.x to confirm whether any of these behaviours existed back then and will report back.

  • Show HashMap in Datatable. UIColumn with embedded Datatable. Help Needed

    Hi,
    I am trying to display a HashMap in a datatable where the values for each key is an ArrayList e.g.
            ArrayList al = new ArrayList();
            al.add("AA");
            al.add("BB");
            al.add("CC");
            HashMap hm = new HashMap();
            hm.put("ONE", al);
            ArrayList al2 = new ArrayList();
            al2.add("AA2");
            al2.add("BB2");
            al2.add("CC2");
            hm.put("TWO", al2);Now I have a Datatable with two columns. First column shows the key and the second column I again have
    a datatable to show the ArrayList. So I will have one row with a key and the values again shown in a
    datatable. So far I no luck and need some help on how to achieve this. Here is the index2.jsp code I have:

    import java.util.HashMap;
    import java.util.List;
    import javax.faces.component.html.HtmlDataTable;

    public class Index2 {
        private HtmlForm form1;
        private HtmlDataTable dataTable1;
        private HtmlDataTable dataTable2;
        private List entrySet;
        private HashMap hm;
        public Index2() {
            ArrayList al = new ArrayList();
            al.add("AA");
            al.add("BB");
            al.add("CC");
            hm = new HashMap();
            hm.put("ONE", al);
            ArrayList al2 = new ArrayList();
            al2.add("AA2");
            al2.add("BB2");
            al2.add("CC2");
            hm.put("TWO", al2);
            entrySet = new java.util.ArrayList(hm.entrySet());
         //here it only prints two rows as i have two keys but on the output it
         //does not come up fine
            for (int i = 0; i < entrySet.size(); i++) {
                System.out.println("==== " + entrySet.get(i));
        public void setForm1(HtmlForm form1) {
            this.form1 = form1;
        public HtmlForm getForm1() {
            return form1;
        public void setDataTable1(HtmlDataTable dataTable1) {
            this.dataTable1 = dataTable1;
        public HtmlDataTable getDataTable1() {
            return dataTable1;
        public void setDataTable2(HtmlDataTable dataTable2) {
            this.dataTable2 = dataTable2;
        public HtmlDataTable getDataTable2() {

        public void setHm(HashMap hm) {
            this.hm = hm;
        public HashMap getHm() {
            return hm;
    }Now when I run this application the keys are shown in the respective column but values are coming up as
    [AA2, BB2, CC2] in one row rather in a separate Row as I am using a Datatable inside UIColumn to show the values.
    Here is what I see in the output:
    keys        Values
    TWO         [AA2, BB2, CC2]
                [AA, BB, CC]
    ONE         [AA2, BB2, CC2]
                [AA, BB, CC] As above output is not correct as it shows both list values in front of each key rather than what those
    keys are tied to. I wanted the following output:
    keys        Values
    ONE         AA
                BB
             CC
    TWO         AA2
                BB2
             CC2So I can do sorting pagination on the values datatable. But currently the output is not shown correctly. Any help
    is really appreciated. My hashmap will be populated dynamically so wants to show the key and values in separate column
    but also need to show the values in an embedded datatable as the list can be huge.

    Rather use a Collection of DTO's. See http://balusc.xs4all.nl/srv/dev-jep-dat.html for some insights. There is also a section "Nesting datatables".

  • Photomerge settings help, performance settings?

    Having issues using photomerge with the latest version of Photoshop.  I have about 120 images that are 16 mp RAW.  What should I have my Photoshop Performance settings at? Cache Levels and Cache tile size?  Also how much ram should I use?
    My system settings are 18 gig of RAM, Core i7 920 like 4 different hard drives, Nvidia geforce 570 HD
    I was using windows 8, now trying 7 but they still both crash and or take hours with no results.

    I suggest Cache Levels = 6 as this is shown to speed Photomerge up vs. a setting of 4..
    With 18 GB of RAM in your system I'd suggest settiing Photoshop to use 90%.  But 18 GB of RAM is going to be WAY too little for 120 images of 16 megapixels each.  48 GB or more (possibly much more) would be helpful for that big a stitch.
    Make sure you have a HUGE amount of free scratch space available - I mean at least 400 GB or more.  Scour your system for Photoshop temp files left behind from your past failed runs.
    Also, what's your ultimate goal in image size?  Do you really need to stitch the images together after conversion to the full 18 MP size?  Maybe you should set Camera Raw to deliver conversions at a smaller size to reduce system resource usage.

  • GTT helps performance - one day to be several minute

    I have a a case like this:
    for rec (select *
    from gl.interface
    where accounting_date between...
    order by c1, c2)
    loop
       -- concate some columns of rec
       -- do update gl_interface
    end loop;it takes about a day to generate notepad report from this query (the records is about 6.000.000).
    And after along day, i resolve it and it takes only several minutes to generate the report.
    What i am doing is these steps:
    1. create global temporary table that delete records after commit. And create some indeks, like rn that is row_number() over (order by c1, c2)
    2. ITAS the gtt with select * , row_number() over (order by c1, c2)
    from gl.interface
    where accounting_date between
    3. change the cursor query above in my oracle form:
    for rec in(
       select *
    from gtt
    where accounting_date between...
    order by rn
    loop
    end loop;
    update gl_interface
    set...
    where exists(
      select ..
    from gtt...
    where col1 =...
    )I still wonder how it works? and what is the drawbacks of using this gtt? tx.

    is it because i put much of the pl-sql statements in my select-sql?Likely because you have reduced context switching between the SQL and PL/SQL engines. By selecting rows in a loop and updating or inserting for each row selected, you are constantly switching back and forth between PL/SQL and SQL, and that is known to be poor for performance. Using a GTT will help improve things because you are reducing the amount of context switches, but then if the data is already coming from database tables, you shouldn't need to use a GTT in the first place... as just doing it directly from the database tables, using something like MERGE will do it all in the SQL engine anyway.

  • Texting and deleting calender help!

    So recently, only the past few weeks, while texting at random times, the screens would go blank, not showing any words or being able to type or send anything. It happened earlier today and when I checked after it finally fixed itself, it deleted the whole calender. Everything from months back, gone... Wondering if anyone else had this issue, or is there anyway to restore what was in the calender. I would rather not restore it, it would be the 2nd time I've had to since I've gotten it in March. Any tips would be useful!

    Hello CassandraApril
    Welcome to the BlackBerry Support Community Forums.
    Sorry to here the calendar is missing from your device CassandraApril!
    The BlackBerry Z10 smartphone sounds to be having a physical issue with the screen itself. I would have your wireless service provider take a look at the device in order to determine if the issue is hardware related.
    However the calendar missing is another issue I would like to address.
    In some cases the calendar data is not missing but however removed from your view. The "Manage" function of the calendar application can remove calendar events from your view.
    In order to check if the calendar events have been removed from view please follow the below steps:
    1. Open the calendar
    2. Swipe down from the top
    3. Select "Manage"
    4. Check all unchecked calendars

    Dear Vishal,
    I checked the NOTE and found that if the IE 7.0 is installed, the GUI version should be the version in the list below or higher:
    o SAP GUI for Windows 6.20 Patchlevel 64
    o SAP GUI for Windows 6.40 Patchlevel 20
    o SAP GUI for Windows 7.10

    Hope for your help.
