With the help of Data Pump for Migration

Hi all

Version of database - 11.2.0.3

RHEL 6

Size of the DB - 150 GB

I have to run a Migration of database from one server to another (AIX for Linux), we will use the data pump Option, we will migrate from Source to the target using schemas expdp option (5 patterns will be exported and imported on the target Machine). But it won't go live for target, after that the development of this migration team will do a job on this machine target which will take 2 days for them to fill in and to cultivate these 2 days, source database will run as production.

Now, I have obligation which, after the development team, complete their work that I have to the changes of 2 days of source to target after what target will act as production.

I want to know what options are available in Data Pump can I use to do this.

Kind regards

No business will update something that has some data that are no longer representative of live.

Sounds like a normal upgrade, but you test it just on a copy of the direct - make sure that the process works & then play it comfortable once again, but against your last set of timely production data.

Deans suggestion is fine, but rather than dropping coins and importation, personally I tend to keep things simple and do it all (datapump full schema if it is possible). Live in this way, you know that you put off, inclusive of all sequences and objects (sequences could be incremented, so you must re-create the fall /). Otherwise you are dividing a upgrade in stages, several measures to trace & more to examine potential conflicts. Even if they are simple, a full datapump would be preferable. Simple is always best with production data

Also - you do not know the changes that have been made to upgrade the new environment... so you roll this back etc? Useful to look at. Most of the migration would be a db via RMAN copy / transport-endian, as you must also make sure that you inherit all the subsidies system patterns, not only summary level.

  • EXPORT ONLY THE TABLES IN A DIAGRAM WITH THE HELP OF DATA PUMP

    Hi people,
    Nice day. I'd appreciate if I can get a data pump command to export the TABLE object in a specific schematic.
    The server is a node RAC 4 with 16 CPU per node.
    Thanks in advance

    If all you want is table definitions, why can use you something like:

    expdp username/password = mon_repertoire dumfile = my_dump.dmp direcory tables schama1.table1, schema1.table2, happy etc = metadata_only = include = table

    This will only export table definitions. If you want the data, and then delete the content = metadata_only, if you want the dependent objects, such as indexes, table_statistics, etc, then remove the include = table.

  • With the help of data values for the selection of members

    Hello everyone:

    I know there are operating functions, with members, strings, names of members... so that you are able to convert a string to a member (@MEMBER) and vice versa.

    But, is it possible to use a value of Member to select someone else?. For example, if in the account dimension, I'm a member of 'parent' with value '100'. Could I put a value, using the value '100' in the '100' member registered in 'parent' to select this member. So if its value is '200', I should put in '200' member.

    Thank you

    Kind regards

    Hello

    First, you insert the CDF, essbase server. in the zip file, you have a small description how draconian make zip archive contains a file bat with a script maxl who do all the work. then restart the essbase server and then a new list of functions should be available on the script calc under Group Editor "functions only the user".

    Here is a small piece of code I created for my current project.

    This store a substring product code number on the cube

    "Produccion_pan"->"Prod_CC_4"->"Referencia"=@JgetDoubleFromString(@SUBSTRING(@NAME(@CURRMBR("CompCosto")),6));
    

    then I read that number and use it again as a member of another Sun name

    "Produccion_pan"->"USD"="Produccion_pan"->"USD" + "Prod_CC_5"->"M3"*"Disponible"->"Total_Puesto"->@MEMBER(@CONCATENATE("PP_",@JgetStringFromDouble(codigo_p,@_false,@_false)))->"Coeficiente_v";

  • With the help of large paintings for a random word generator

    Hello

    I am currently working on a random word generator quiz this kind of thing, you press a button (click/touch) and a random word appears, you must then click/touch again to choose that if you think it's a real word or a compound word, whenever you get a right you get a point. No problems so far, I have all this works with the help of a few global variables (eep) and a couple of berries that store the image names and the true/false values so that they are real or not.

    Now that I'm starting to fill the building with the final content I am realizing that the table of the image is going to be huge, some 250 more entries and currently he is sitting on an action to click the button. Is it the right way to go about this or is there a better way to store the information about all? In a text or .js file maybe?

    All boards that much appreciated, thanks for reading!

    Hi spiders.

    If you push 200 objects a picture, you probably want to use a loop "for".

    Alternatively, if you load an image at random, and they are all named in the order, you can try something like this:

    wordCount var = 200;

    var imageIDToLoad = Math.floor (Math.random () * wordCount); / / Choose random num

    Substring var = ' images/word'+imageIDToLoad+'.png';// added this var to work around quotes

    var imageURL = "url (" + subString +")"; / / create the URL based on the random ID num and substring

    var randomWord = sym.createChildSymbol (imageURL, "wordWrapper");

  • With the help of digital input for Boolean control?

    Hello!

    I have spent a lot of time to search but have not found a solution to this...

    I have LV 2015 with chassis NI 9188 and module NI 9425 DI.  Try to use the input signal to assign a State structure machine program and/or events in real time.  It would be acceptable to have an indicator show the status of the input line, since I can use it elsewhere with Value (Signaling).

    Please do not ask for the code - the problem is quite simple.  I just want to use the digital inputs to program control as a T/F.  I want just the program to analyze the State of the input and decisions - a bit like a PLC.

    All I seem to be able to extract is data of digital waveforms with a task DAQmx.

    It's not a trigger - I already use a trigger to start the analog acquisition.

    Formulate the problem in a simpler way...  What to do if you had a digital input module and you wanted to see the status of each input line in the form of a LED on your face in real time.  How would you do it?

    I really appreciate the help!

    I would like to write what has been read to the Terminal.

    From what I can tell, you want to just read a single static value from your digital line.  You can then simply read the value of one and do some logic with her.

  • With the help of data contained in an event.

    I'm trying to understand how to use the data of an event to set the selectedIndex of a comboBox control property.  If I hardcode the number 4, as it is in the example below, the function sets the selectedIndex property correctly.  When I run the debugger, (4) data under event.itemRenderer.data.ConstructionPhase.  However, if I try example B or C, Flex builder gives an error... D example gives no error in flex builder but then when run.  Please, how can help I get the value of the event to be used for the function?

    Example has (it works, but may well hard-code the value!) :

    openAddForm();
    addEditItem.label = 'Edit ';
    for (var i: int = 0; i < ConstructionPh.dataProvider.length; i ++) {}

    If (ConstructionPh.dataProvider [i]. ConstructionPhaseId == 4) {}

    ConstructionPh.selectedIndex = i;
    break;
    }

    }
    }

    Example B (Error message in flexbuilder = "" 1119: access of the itemRenderer property possibly not defined through a reference with static type flash.events.Event "")

    Cool. From what I see, you need to find a record in the drop-down list that is based on a

    shared value in the record of DataGrid. So in summary, you're screwed.

    No, no, I'm kidding! It's Friday and I'm looking forward to the weekend. How about you

    will be too, after seeing the solution to your problem!

    Answer: Search through data provider for your ComboBox for the value in the

    The DataGrid SelectedItem. Then set the selectedItem of the ComboBox as a result.

    So the trick is to then assign an ITEM from the dataprovider of the ComboBox

    selectedItem property. Voila! Don't bother with the selectedIndex property and not looping

    necessary.

    Oh and another thing: when you are working with the DataGrid control, you use the

    ListEvent, not the event ol ' ordinary that you were using. The ListEvent contains the

    object selectedItem from the data provider. just what it takes for this method.

    Oh, what? Not quite clear? Ok. Let's get this party started...

    There are two things you have to remember to achieve:
    (1) to find a Collection of table, you create a cursor. Just like a database.
    (2) the Collection of table should be sorted before searching in it. Mandatory!

    OK, here's an example I want you to try. Not knowing what your data looks like, I

    had to pretend, please excuse my laughable attempts of creating classic data

    that could be used in your business.

    Notes:
    (a) sort and find takes time on large data sets. But made a loop,

    which is what you were doing.

    (b) you must return the ComboBox control to its 'home' State after sorting and

    research on the field, otherwise the user will see a different kind

    order each time it opens.

    This example implements everything above. Enjoy!

  • With the help of data from the database on my Web page

    Hello

    This is probably a simple great question, so I apologize in advance. I looked through a lot of information on BC and I can't seem to find the answer to my question (although a lot of it seems to go over my head that I'm a n00b full BC., and I feel that my hands are tied without being able to just stir up the something in Python or PHP!).

    I am trying to create a Web page that displays a single product (the entire site exists just for 1 product), and the user can click on the color chart of different color in order to customize it. I would like my client (owner of site) so you can easily add new colors (using the hexadecimal code) for different parts of the product.

    So I basically just need a place where the client can enter these values, and then I can write on my page in JavaScript format and build dynamic page using JavaScript.

    It seemed that the way to do would be to create a new "Web App" inside the BC. I did, and I created a "Web App Item" called "Data". Under "Data", I added a 'field Item' named 'Color', which is a multiline text area. I entered a few different hexadecimal codes like this:

    000000

    FFFFFF

    003366

    (I thought that I can analyze the lines with JS)

    The problem, I comes across however, is to know how to enter these data in my source code on my Web page? I created a Web page and I put the code in it:

    {module_webapps, 6042, one,}

    but this will display a list of links, with a link to 'Data', and then if you click on "Data" you go to a separate web page that says only: "Data" in this topic. Very strange.

    Is there a way I can get the data entered here in the source of my Web page? (Or is there a better way to do it?)

    As a more general question... It's basically just how use BC as a CMS and have custom fields that you can then access your web page. A bit like plugin, WordPress Advanced Custom Fields, if you're familiar with that. (I know that's not WordPress, but just a way that I can access certain values that my client has entered in)

    Thanks in advance!

    Heather

    You may be better to use electronic commerce and assign different attributes for your colors?

  • With the help of IVI driver for delay in the MSO6104A of reading

    Hello

    I have the IVI driver NOR for the scope of the MSO6104A. The driver is functional, and I managed to use it.

    My scope has a function of delay between two different channels. But, how to read delay help scope step IVI measurement?

    Is there another way to read this measure?

    Thanking in advance

    As far as I know, without delay only is not supported a measure of IVI function. For example, you can complain to ivifoundation.org first. Or, in a code module, you can use the driver of specific instruments for the measurement. This would make the application "no - IVI" so in the first place, most of the grounds using IVI disappeared. Or retrieve the waveforms from each channel and calculate the delay in a code module.

  • With the help of vertical area for a LogScreen Manager.

    I don't know, I must be doing something wrong here, can someone me hint. I am doing as a logscreen using vertical field Manager and adding my logs for the Manager as labelfields, but the screen doesn't seem to be scrolling beyond the front view.

    I do not understand what I need to fix here:

    Line 138, column 37: there is no attribute "align".

    ' < table width = "585" border = "0" align = "" " center" cellpadding = "0" cellspacing = "0" >

    You use the attribute named above in your document, but the document type, you are using does not support this attribute of this element. This error is often caused by incorrect use of document type "Strict" with a document that uses frames (e.g. you must use the "Transitional" document type to get the 'target' attribute), or using extensions such as "marginheight" owners (it is usually fixed by using CSS to achieve the effect desired instead).

    This error can also occur if the item itself is not supported in the document type, you use, as an undefined element will have no attributes supported. in this case, check the error message undefined element for more information.

    How to fix: check the spelling and case of the element and attribute, (remember XHTML is all lowercase) or check that they are both allowed in the chosen document type and/or use CSS instead of this attribute. If you receive this error when you use the < embed > element to incorporate flash in a Web page media, see the FAQ on valid flash.
