Potential performance issue with the mobile app

Hello

I'm working on a small mobile project to see how the view system and its performance.

To see what is happening with the objects, I tried the Profiler today and I was surprised to see that the Navigator object does not use view previous instances.

For example if I navigate between 2 displays the browser instead of using the 2 objects already created, it creates each time it's push() function is called.

Maybe there is something that I do not understand that it makes the behavior desired, if so can someone explain it to me please? If this isn't the case, then I'm worried about leaks memory after an intensive use of the views in the app.

I have to make it clear that I do not use any weird code that could disable the browser work properly, my app is less basic at this point and I'm also using weak references on each event listener to avoid problems of memory.

I didn't not try your code, but you could run this question: http://bugs.adobe.com/jira/browse/SDK-28396 , which was set after the beta version.

  • Performance issue with the submodels

    Hello
    I'm working on submodels and my requirement needs only one main calling location several specific submodels (a location may have several own submodels, e.g.: US_subtemp1, US_subtemp2, US_subtemp3... in the same way to other locations).
    I would like to know is there any performance issue associated with calls in the submodels and on how this decrease in performance can be minimized.

    Kind regards
    Arvind

    Use of the submodels with components imported alongside repeated sections in the main template layout is not recommended when the number of repetitions is high and the size of the document is large. BI Publisher optimize the xsl transformation internally, but it is not applied to xsl inside models of void.
    One of the extreme scenario is a main model set only a repeating section that matter a submodel of the header and the footer.
    A body of the repeating section is defined in the subtemplate. In this scenario, there is no xsl optimization made and you can easily see some differences in performance.

    As long as you don't need to repeat the layouts of submodels, you don't need to worry about this performance issue.

    Thank you

  • performance issue with the Oracle SQL query

    Dears

    Good evening

    I am new to begin to use Oracle SQL, I have a sql query which takes longer to run in production.

    Each table in the query contains 1.2 million records and DBA suggested using the "Oracle - tips. I don't have good knowledge on this subject and the difficulties to implement this advice for imrpovise performance. In the product the jobs Informatica are failed and stuck with this problem of query performance.

    I ask this forum for an emergency for me to solve this problem by using "advice". kindly help me.

  • Performance issue with the method extract in 11g

    I am new to Oracle XML DB. I'm having a problem with an example simple Java application designed to test the response time. I can't find an answer to this question.

    It takes about 1/2 second, whenever my Java client makes a call to the method "extract" of XMLType. Extract is called 3 times for each row returned in a result set. It takes 1 1/2 seconds to process 1 line. With a result set of 55 lines, it takes about 1 1/2 minutes to process the entire result set.

    It seems to me that an appeal must be get done to retrieve the data from the server to each snippet of time is called. This performance is unacceptable and will not evolve. This seems to be a lazy loading problem that could be treated with the configuration; but I still need to find something specific documented.

    Is there something that can be done to solve this problem or is it typical performance?

    I use a binary XML storage. I created a XMLIndex; but it made no difference. Does not seem like an indication that much of a difference, since the problem occurs when you access XML different values in the same line...

    The extract method is implemented in the classes of the JAVA API provided by the Oracle client installation.

    Just to clarify things, this forum is related to a feature in the Oracle database. The API you mentioned and you use are provided by another group within Oracle (I think). In addition, the used API .extract does its job fully without communicating with the DB. You can check this to hard code in an XML response and disconnect your computer from the network before you run the logic of analysis and it would continue to operate.

    The fact that this method is removed must have something to do with its inefficiency

    The disapproval that I mentioned is only in what regards the SQL in the Oracle DB. As noted above, the used API lives under a different set of rules, so I can't speak to that. There is probably a forum for the API, but I haven't been looking.

    Back on topic, a possible rewrite for your SQL statement is (untested)

    select aex.APPLICATION_NAME, aex.VERSION, aex.EVENT_TYPE, xt.sendingSite, xt.receivingSite, xt.eventID
      from AUDITED_EVENT_XML aex,
           XMLTable('/*/MSH'
                    PASSING aex.xml_event_content
                    COLUMNS
                    sendingSite   VARCHAR2(20)  PATH 'MSH.4/HD.2',
                    receivingSite VARCHAR2(20)  PATH 'MSH.6/HD.2',
                    eventID       VARCHAR2(20)  PATH 'MSH.10'
     where EVENT_TYPE = ?
    

    If you have problems with this, just after a small sample XML and someone can twist where I was wrong.

  • Performance issue with the Update statement

    Oracle 10204

    I have a problem related to updaing one performance table.
    only 5000 lines should be updated.
    Hir are some details on the tables/M.V concerned:
    TABLE_NAME     LAST_ANALYZED          NUM_ROWS     SAMPLE_SIZE
    PS_RF_INST_PROD     1/20/2010 1:14:22 AM     7194402          7194402

    NAP_INTERNET     1/25/2010 11:47:02 AM     7053990          560777
    I tried to run the update with two options:
    1. with the plan than oracle choose.
    2. with notes I added.
    In both cases I he collapsed after more than an hour.

    Can any one suggest how to speed it up?

    Below are for the two option tkprof.

    The trick is to join only once, be updated using join views - provided that it is preserved - key or by using the merge statement.

    Here is an example:

    SQL> create table bl_tmp_intrnt (fix_ip_user,service_uid,term_desc)

  • Potential SEO issues with the meta description and h1 tag

    Work on the referencing of BC site and noticed the page markup has more than a description meta tag. I think there must be meta tag single description within the section of the page. If someone looked into this? It would seem that the models have the meta description and then tag when a new page is created, if you fill in the description field of SEO for this page, BC adds another meta description tag. What's going on with that and is there a workaround? I'm sure that this negatively affects the SEO.

    Then there is a problem of h1. An h1 tag is an indicator of what the content of the page. Search engines reduce the value of a page that contains multiple h1 tags. If a page Abuse the h1 tags, this page could be determined a junk page and not be indexed. Again, the model contains h1 with the page logo and many of the pages included with the model (Tribeca) reuse h1 in the body. Is there a css solution to substitute the h1 used in logo template? Would anyone like to gift of the snippet of code I could use for this purpose? I'm really bad with css...  Thank you.

    Well Yes and it is one of the Colombia-British ones. That would be a problem with this model. I think that there are a few things wrong with this pass by the forums so I don't know if the BC was made aware of them but I will go to them about this.

    Remove the meta model files from descriptions if you can yourself and that will correct if all goes well. It is not the norm, I have plenty of time to build sites and don't have this problem if it is not not a problem of system so uncomfortable on this.

  • Performance issue with the query when join OKS and tables of the IB

  • Performance issue with the point of SHUTTLE with 2000 records

    Hello

    I have a FORM with a SHUTTLE item based on a LOV which is to have about 2000 records.
    When I submit this page (CREATE/APPLY the CHANGES), ask it something about 3-4 seconds to submit.

    When I delete the SHUTTLE of the form point, the sending process is very fast... say 1 sec...
    so it takes more time when we have a SHUTTLE point with 2000 records.

    So, how do I fix this perfomance?... any suggestions?


    Thank you
    Deepak

    Deepak,

    When you have more number of records to select the list, Select Multi, elements of the shuttle, then it will take more time to render the page. In most cases, you cannot remove it.

    Check the performance of the underlying query LOV. If it is a complex query, no doubt, you can see his plan to explain and you can enter.

    Alternatively, you can move this deadline to the popup page. I want to say, create a custom page to pop up and provide multi select such items from the shuttle on this page. Allow the user to select the point of shuttle options in the popup page and return values selected to main page shape :)

    See you soon,.

  • I have a license of Adobe Acrobat Pro DC - I can use in the mobile app?

    Hello!

    I recently bought the license for Adobe Acrobat Pro DC for my computer and now I want to expand my possibilities with the mobile app. Is it possible to somehow use the license purchased in the mobile app? Because I'm asked to buy additional packets when I want to, for example, to export a pdf file?

    Thank you!


    Mikael Damar

    Hi Mikael,

    I'm can understand your concern & will guide you in the right direction. Can you please let me know if you have a subscription to Adobe Acrobat Pro DC or it is a perpetual license?

    As with a perpetual license, you will be able to use the features on the mobile App using the same license, and it will ask you the extra envelope. However if it is a subscription simply simply Sign In to the mobile App using your Adobe ID with which you sérialisiez the Acrobat Pro DC on the computer to use these features.

    Kind regards

    Back to 6.0, you need to uninstall 6.1 (https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html)

  • Are there known issues with the decommissioning of a folio to v20 v24 in CS6?

    Are there known issues with the decommissioning of an app to v20 in CS6?

    our application is v20, we have created the folio initially as v24 but could not get the corresponding app approved by apple, so we rebuilt the folio as a v20 but it errors on the download, ideas?

    You will need to completely recreate the folio.
