Is the normal behavior of assign only a tablespace to a schema?

Hello

I just posted a thread that has successfully met, but with the new information, I doubt again:


We have users who store their objects in a schema.

Usually, if the person / organization behind what the user wants to put in place a different another application, it will create a new user for this purpose to have stored logically its objects.

But maybe sometimes that's not possible because tables and DB objects can have a common part that must be shared by both applications and individual information (data) only can be logically stored in the same place (even though I know a single table may have its data in a tablespace, and also the data in this table in a different tablespace).

I guess that's a good idea to have different tablespaces, such as one for the object and the data that is common, one for data and the objects of the application1 and one for the data and objects in the application2.
In doing so, we can put a tablespace offline to change the application1 objects without affecting the operation of application2.


So, my questions:

My argument is correct?

Is - this frecuent in the business having a schema (user) data were separate to the tablespaces serveral?.

Or is the normal behavior of not only assign a tablespace to a schema?

Wouldn't make more sense to have two users / permissions on objects and patterns?

Greetings

In my experience, small applications (with respect to the number of objects and the total size of the data) use usually one or 2 drawings and single tablespace (sometimes 2 if they want to separate from the data in the tables and indexes in the table). But large scale as ERP software applications tend to use multiple schemas and several storage spaces. An example interesting is Oracle Applications model Tablespace (OATM) described on page 3-5 in http://download.oracle.com/docs/cd/B53825_04/current/acrobat/121oacg.pdf.

This Oracle Magazine article documents the practices of separation good security scheme:

  • Satellite A500 - on the screen and the volume of media keys control the normal behavior

    Hello

    On my laptop Satellite A500, I have no screen 'volume bar' when I use the media keys of volume (located between the speakers). I find this odd, like many other phones that I use (including the Toshiba) have this feature. In addition, the volume bar between the - and + media symbols of the keys never lights upward.
    Could someone please confirm that those are normal behaviour? (Note that my Fn keys, utility eco work and so on).

  • Hold the tab behavior to be same with IE by clicking on the links in the bookmarks toolbar

    In IE, when I click on a link to the bookmarks toolbar, it opens this link in the tab in which I am working. In Firefox, however, it always opens a new tab. I'd rather have Firefox behave as it opens a new tab when I've specifically it asked to do so, or when a URL linked to a page that would normally open a new window (in this case I prefer to open a new tab instead - and I found where = that = parameter is but has no effect on my particular problem).

    Note: can I asked this before but I either lost the information, or did the change once my system and I forgot about it. I'll put up a portable newly bought after my "old faithful" gave the soul after four years of long and satisfactory service. I will miss greatly.

    Hello, Steve.

    Normal behavior of Firefox is to open Favorites in the current tab. You may have a problem with some Add on Firefox which is an obstacle to the normal behavior of your Firefox. Have you tried to disable all add-ons (just to see) to see if Firefox goes back to normal?

    Whenever you have a problem with Firefox, whatever it is, make sure that it's not one of your modules installed, be it an extension, a theme or a plugin. To do this easily and cleanly, start Firefox in safe mode , and then select disable all add-ons. If the problem goes away, you know that it's an add-on. Disable them all in normal mode and allow them one by one until you find the source of the problem. See this article for more information on troubleshooting extensions and theme. You can troubleshoot plugins in the same way.

    If you want supported for one of your modules, you will need to contact the author.

  • Background layer unlocks and becomes the normal "no flat" layer after using the crop tool in PS CC 2015.1 (a different behavior for older versions of PS)

    Hi all

    I found that it is more difficult to explain than I thought

    I don't like the new behavior in the latest version of Photoshop (CC 2015.1) regarding the way in which the background layers automatically unlock and convert to regular layers after using the crop tool. It's completely different to how things worked in previous versions, where a background layer remained in locked state flattened after using the crop tool.

    I get a LOT of images and this change has added an extra step to each image that I harvest, because I flatten the layers after cropping before saving the image. I looked through the preferences but cannot find a way to change this new behavior. Am I missing something?

    Thanks in advance for your help

    See if checking Delete the cropped Pixels in the tool options makes a difference.

  • Frustrated by the strange behavior of the command SET up FIRST HP!

    I tried to define a function using the command SET the. The function is F = G * M * m / r ^ 2. No matter what I try, I still get the same generic error: INVALID INPUT. I went to the guess, user manual, half a page of information about the command SET. Better nothing, but far from what you would expect if the manual is YOUR main source of information on how to use the calculator. In the first instance, an error, here's what I discovered:

    (1) name of the function cannot be long 1 letter. They can combine the capital letters, small letters and numbers...
    (2) variable must be UPPERCASE
    (3) variables can start with a letter and followed by a unique number. ONLY THAT, nothing more

    Can someone, confirm please?

    It is quite limited. So now, instead of the calculator not work for me I have to work for it. This is the formula I: F = G * M * m / r ^ 2 and that's what the calculator would accept in the screen SET: F12 = G * M1 * M2/R ^ 2, see figure 1. Quite annoying, but I can leave with it.

    As you know, G is the gravitational constant: 6.67384 x 10 ^-11.  The calculator is supposed to to remember, so why type it again?  I went to CASE view, called my function, putting fake numbers, just to try it, had G of MAJ > units > Const > physics.  This is how my edit line looks like: F12(6.67384E-11,100,300,25)... See figure 2. Guess what? An ERROR GENERIC, no idea of what the calculator don't like on this subject. After a while, I discovered he does not like the E in 6.67384E - 11, she she likes 6.67384e - 11, and then it throws another error (Bad arguments number) see figure 3. I check everything, it looks all right.

    I decided to try my LUCK in the main screen. Everything works perfectly. He doesn't get complaint even the 'E' in G, and I get the result expected (figure 4).

    I went back to the screen set and passed under the name of the F12 function to Forc, put the numbers again, MAGIC, now this market (see figure 5).  So, after all, it seems to be the calculator do not like the numbers the function name, but he didn't complain. Come on guys, you do not buy a top of the calculator online to go through this torment.

    Can someone tell me what is the reason for the bizarre behavior?

  • NB200 - allocated for the 128 MB video card only

    Hello!
    in the specifications, we can allocate 224 MB of memory for the video card, but in windows, we can assign only 128 MB.

    Someone at - it a solution?

    Hello

    The video RAM is shared with the normal RAM (system memory). This means that you can get up to 224 MB of video memory to it of necessary, but if the graphics don't need of more memory, 128 MB are only.

    And, you can change or control by yourself. This is done automatically and it of really not necessary to change something.

  • Delete the folder behavior

    I have a paintings of master / detail, pk and fk, but fk has no option "On Delete Cascade"

    -in the form of two tables listed above, I changed the "Delete Record" behavior to "cascading,"

    i surprised he deleted the master records and details of the form and tables too.

    is this a normal behavior?

    Yes, it is a normal behavior.

    "Delete folder behavior" = "cascading" means forms deletes all associated detail records - you don't need "On Delete Cascade" option on the database side.

    See using forms:

    ' Delete the property behavior recording - editing cascading:

    Allows the main record should be deleted and automatically removes the detail records in the base table of this block details at the time.

    In a master relationship / detail-detail, where relationships are nested, only in the block of immediate detail records are deleted (destruction in is not cascade on several levels of a chain of relationship automatically).

  • Contour Contour - a normal behavior?

    This is a strange anomaly, that I ran.

    I drew an open unique with its ends crossing path (line see black in the photo below).

    When I saw the line everything runs into a place that overlap (see red shape).

    Separate ways produce objects that overlap when indicated, so I would have expected the form in my example overlap.

    It's like a Pathfinder unit has been applied.

    Outline_stroke.jpg

    Steve,

    Is this a normal behavior? Illie has always done it this way?

    It is always difficult to determine whether a behavior is normal or even rational, but she always behaved like that.

    I think she sees a path (self overlapping) as a single object and is unable to decide a split in parts, although there is an order of anchor Points; and after all, a path overlapping free can have only a single segment so it is not always possible to consider an order of segments.

    Apart from this, a split would lead to separate paths, if not (with coinciding ends that could be traced if paths had to be traced)?

    And if the order must appear without the path cut it out, it wouldn't require strange solutions, apart from him give a splitting headache, try to understand?

  • When I try to print, and the HTML document firefox downloads only a blank page.

    I sent some documents in pdf format. I chose to download, the download arrow fired to the blue. I was then able to select the file. Opening the page print the normal browser and I was able to print. I need to reprint pages and this is where my problem comes in. Now when I try to select the firefox file shows that it is downloaded the file but when I select the downloaded pdf firefox only to download the doc again and displays a blank page.

  • Change the default behavior for the properties of the list

    It is about creating an outline numbered in the body of an email. Choosing the appropriate command-line icon icon, the numbered list will start to "1" (as it should).

  • Latch up to the liberated behavior

    Behavior behavior latch - until the-released from switches seems a little strange to me, and I was wondering if anyone could shed some light on a question I have on this subject.

    As a quick experiment, I created a very simple VI containing only a while loop with a structure of the event, some controls Boolean latch - until the released and digital indicator.

    What I expected was that the display will show '1' and '2' then one of these Boolean controls was depressed after having released it. What I found, it was that it displays "2" after pressing the button, but stayed like that after it freeing.

    Using the window Inspector events, I checked that the occurrence of the event was made to fire when I pressed the button and when I got out, but in both cases, it seems to be reading the key as 'true '. I find that really odd - would be unwise for the button to read also true in a case and false in the other?

    To get the expected behavior, I had to do something very ugly:

    Since the button seems to be in the same condition in the two executions of the case, has no way to distinguish between the press and release of the events except keeping the external State to the structure of the event. My question is basically: why LabVIEW developers have chosen to design it this way? What is the logic behind this?

    In the structure of your event, you have an OLD VALUE and NEW VALUE provided to you.  You can do meaningful with those if you need to distinguish further the transition.

    Consider simply using the SWITCH up PUBLISHED mechanical action,

    Which generates a VALUE CHANGE event on the press and a VALUE CHANGE event on the release.  The NEW VALUE allows you to distinguish which.
