With respect to the analysis and collection of statistics

Hello

Why the collection of statistics is necessary in the DB?

Thank you

Hello Balmo-Oracle

You can start reading this document for example: Managing optimizer statistics

or this: http://www.oracle.com/technetwork/database/bi-datawarehousing/twp-optimizer-stats-concepts-110711-1354477.pdf

The best way if you check yourself in google.

  • with respect to the footer and header area

    Hello

    IAM new to this oracle application express and in the learning process. I want to know about the attributes of the header and footer of the region and for these attributes may be used and I found some java script can be placed in the area and footers if body and html header are present in the page. Anyone can throw some light on this.

    REDA

    Hi reda,.

    There are many things you can do with the parameters of region header and footer area. These would all be the content of the page you want to be added immediately before or after your report (or how whether the region contains). Any valid HTML tag should be ok, it can be placed between the BODY tags on a typical HTML page. Many users will add images, links, introductory text or footer information in them. You can also add javascript if you wish. Some will insist that you use the parameter header HTML on the page definition to do this, however, if you click on the words "Région Footer", you will see that there are several replacements of special channel available on in the foot of the region (e.g. #TOTAL_ROWS # will tell you how many records there are in the report). They can be used for a direct output on the page or you can use the in javascript. In addition, unless you use something like JQuery, you can use the foot of the region in the region in the final on the page to run scripts of type onload.

    The header HTML parameter can be used to post a link specific javascript and/or css files to your page (rather than add them to the page template - which would make available to all the pages that use this template).

    The HTML body parameter is only used to add attributes to the BODY tag, when the page is rendered. It can be any valid attribute - for example, you can add a style attribute that sets a background image for the page. The only thing to note here is that you cannot add an onload event handler if you also set the adjustment of focus of the cursor on "First item on the page" because it uses the event onload as well.

  • With respect to the Variables and safety

    Hi Experts,

    I'm confusion when implementing security can any one answer for these:

    1 > what is the difference between column-level and security level of data security or both are the same.
    2 > when you want to implement the time to level of data security we use session variables (for writing query and fill particular user to display only a particular area) or directly we must give permission for group and users in the tables of presentation layer and layer the presentation of properties of table column (column-level security).
    3 > session system variables are used only to authenticate use should not use other good things. In what situations we must use session independent of system variables.
    4 > if we apply security at the level of the object directly, we can do in the web presentation and the right level layer no need to use variables.

    Hi reda,.

    When we have implementation of security at the level of the data without the need to create variables directly in the groups assign us permissions and adding the filters for this particular group visible only particular brand and should not visible to everyone.

    A. Yes, your writing, but I understand your confusion see my comment

    So ultimately, no need to create variables for the right level of data security. Please let me correct if I did something wrong.

    A. when it will use variable for the means of security to the level of data if your use of the authentication of external table via the database table, then you need to use ok session variables...

    See the link for your details below.

    Is there a way I can trigger my characters triggers in the world? I want to listen to with him in the obs and be able to do while ingame triggers

    Thus, control triggers in CH all streaming a game via OBS (like having your character in the corner and your fullscreen game)? To control triggers CH I believe that enforcement must be active, so I couldn't choose another app/game on PC and press keys to trigger (if I CH running and switch to Photoshop, for example, keyboard triggers will not currently work). But I have not personally tried something like this yet - there must be some sort of solution (2 computers?). I know that we're working on more ways to feed and export your character alive in future versions, so ideally this workflow can be easier on the road.

    have 5 LR and CC. The folders are different, some are missing in the CC. And some Collections are not available in CC. I'm looking forward to use CC rather than LR5 so how can I make the folders and collections even on each?

    Hi cjohnm,

    You can use the 5 Lightroom Catalog and improve it in Lightroom 6, therefor all folders and collections will be identical in both version.

    Open the Lightroom all holding the key Alt/Opt and select only the 5 Lightroom Catalog and it will switch to it.

    Let us know if that helps.

  • Where custom workspaces are stored on disk (with respect to the PS CC 2015 and Windows 8 +)?

    My work computer gets reconfigured every night, and it is not only annoying, but also a productivity problem that I have to keep resetting all the panels in the way that I'm comfortable. I need to be able to transfer my workspace personalized to my computer at home for my work computer. It would be so much easier and faster each day to be able to use a shortcut to navigate to where workspaces are kept and drag - move my custom workspace in. both work and I pay for CC, so we should have the more updated versions CC, so there should not be any compatibility problem?


    Anyway, I found [* \Required\Workspaces\] but I couldn't find my workspace. And when I made two new workspaces with unique names ('banana - rama' and 'fade', stupid names, I thought is in the drive) and tried to search for them, I could not find something.

    Everything that I could Google on the subject was about CS5/6 as well as the address of the file these versions use apparently are no longer in use.

    Assist?

    Saved workspaces must be 2015 in cc photoshop preferences folder in your user folder.

  • Two computers OK, but where are the catalogs and collections?

    I guess I missed something here, but I'm new on this.

    I have an iMac desktop and a Windows 10 laptop. CC of Lightroom installed on both and both work well.

    But I don't think I understand this cloud thing. I assumed that I could create a catalog, collections slideshows etc. on my iMac. Then I could sign and go out with my Windows laptop. Then I

    could sign in Lightroom CC on my laptop and BOOM, there is all the stuff that I created on my iMac on my laptop via the cloud.

    I assumed that all the work that I do was preserved in a cloud of Lightroom, but I now think that I'm wrong. Am I?

    If so, how can I do things on my iMac, and then synchronize with my laptop Windows 10?

    Thank you.

    I assumed that all the work that I do was preserved in a cloud of Lightroom, but I now think that I'm wrong. Am I?

    Your work is usually saved on your local hard drive, unless you use the sync to work with Lightroom Mobile features.

    How do I synchronize Lightroom desktop and mobile application of Lightroom

    The part of the cloud of the cloud makes Adobe refers to the granting of licences where license controls are managed remotely by license Adobe Cloud servers.

    Software installs and runs locally. Œuvre produced by the software is saved locally, unless you choose to use Adobe Cloud storage or use the Lightroom Publishing Services.

    Lightroom catalogs and collections are stored locally.

    synchronization problems between 2 desktops

    Post in the Lightroom forum if you have any other questions.
