With regard to the UPDATING of the data in the warehouse of data using various incremental DAC

My client is planning to spend some discoverer to OLIVIER but before need us answers.

(1) my client requires data to be updated hourly (load using the CAD) because they use a lot of data in real-time.
We do not have many data update (for example 10 bills in one hour + others). How long it usually takes to refresh these tables in data using the CAD wareshouse?

(2) while the table is can getting updated we use this table to generate a report? If so, what is the State of the data? Stale or incorrect (undefined)?

(3) how does updating of analytical work? It is a module at a time or it treats all 3 modules (GL, AR and AP) as a single unit of refreshment?

I would appreciate if I can get an answer to all questions.

Thank you

So much for the answers:
(1) should not be too much trouble for a such small amt of data. Depends on your implementation plan to the DAC that can always be created as new and can be customized to load the data for these tables... (Star Schema) - about 15-20 minutes, because it does so many things outside the loading table.

(2) report to OBIEE will give the previous data because I believe that Cache will be (Shud be) turned on. You will get the new data in the reports after the update is complete and cache is erased using different methods (the favorite voting event)

(3) once again to end analytics or any other module, you'll OOTB plans. But you can create your new plans and run. GL, AR, AP are also provided separately...

Hope that answers your question... You will learn more about running through Oracle docs... especially for DAC

  • With regard to the update of the locations of cards-oracle

    HII everyone,

    In my application, we using mapviewer, which was installed locally on our server, for map rendering and showing the locations of a client like pinball machines.

    Suppose that some places (address, City) is updated map... How mapviewer (which has been installed on our server locally) will update this site all in rendering...

    Thank you

    learner

    It depends on how you got the map features.  Mapfeatures are usually stored in the cache.  If a change in database may not appear in the card immediately.  If, however, given the characteristics of the map as a vectorlayer, then simple vector update updates map.  You should consider two options with regard to the update database process.  You can store the geometry as a function that is updated on the fly as change attributes of database, or you may use a database trigger to update the geometry when the attributes change.  Thus, using a combination of correct space architecture and mapviewer correct functions.

    Edited by: 882600 August 31, 2011 05:51

    There are several ways to achieve this. Perhaps the simplest is to simply catch Exception as std::exception const &, or one of its derivatives, then call what(). However, if you want to use the specific exception hierarchy richer consistency, you can get the equivalent of the what() result by calling getDescription()-> getCString(). With regard to the rankings largely what types of exceptions are "fatal", which would be RuntimeException and its derivatives, but the scope which it was caught in general is going to be more telling.

    What a wrong answer.

    If you have a table with columns a, b, c, d, and you have a compound of the index on a, b, c, the index can be used on the following condition.

    (1) one
    (2) a, b
    (3) a, b, c

    And with the introduction of skip scan limited index that the index can be used even in the first column is skiped. Like this

    (1) b, c

  • With regard to the mode of transport SYNC

    Version: 11.2.0.3
    Operating system: Unix/Linux platforms

    I'm new to Data guard

    It's that I understood on the SYNC mode after googling and read 11.2 doc. correct me if I'm wrong.

    SYNCHRONIZATION (synchronous Transport Mode)
    ======================

    With the transmission SYNCHRO mode, LGWR is not allowed to recognize that a commit succeeded until the LNS confirms that it again to retrieve the transaction was written to the Redo logs waiting in the standby.
    Until LGWR extracted this confirmation of LNS, the database is suspended and the validation operation is supported. That is to say. In the event of failure of a network between the (primary) production database and the standby database which prevents the
    again to be written in the newspapers waiting to roll forward, then the primary database will block.

    SYNCHRONIZATION method is also referred to as method "Zero data loss.

    But there is an attribute called NET_TIMEOUT for LOG_ARCHIVE_DEST_n parameter; Assigned (in seconds) decides how long LGWR should wait to hear from LNS on scripture to redo in Standby Redo Logs.

    The default value at 11.2 is 30 seconds. After 30 seconds, if LGWR cannot hear the LNS on a succesfull write to redo in Standby Redo Logs, process LGWR disconnects from the LNS and acknowledges the primary VERIFICATION and allow
    DB primary to continue treatment even if he can no longer communicate with the day before.

    This isn't strictly "zero data loss" as a VALIDATION has been recognized in the primary despite the entrance of again as a result of this change is not written for the eve SRL. Right?



    Question2.

    In all our Prod DBs, LOG_ARCHIVE_DEST_2 is set to the value below. No idea what type of protection is this DB in?
        MAXIMUM PROTECTION
        or
        MAXIMUM AVAILABILITY
        or
        MAXIMUM PERFORMANCE ?
    service="HEWRMS_DG", LGWR SYNC AFFIRM delay=0 optional compression=disable max_failure=0 max_connections=1 reopen=300 db_unique_name="HEWRMS_DG" net_timeout=30, valid_for=(all_logfiles,primary_role)

    This isn't strictly "zero data loss" as a VALIDATION has been recognized in the primary despite the entrance of again as a result of this change is not written for the eve SRL. Right?

    You'll only no loss of data if you have maximum protection. If the primary is unable to reach the day before, it stops after a fixed delay. Oracle recommend two standby mode if you want maximum protection.

    In available maximum primary will try to reach the previous day in the net_timeout value and whether it will commit the transaction and move. It will essentially drop down for maximum performance until it can connect to the waiting again.

    Check the mode of protection of data.

    select protection_mode from v$database;
    

    Should read: you only have the guarantee of no data loss with maximum protection. You have no data loss with maximum availability until your watch and network are correct.

  • With regard to the creation of the EO

    Hello

    While creating an entity with the subject entity, to step - wizard object 4 (JAVA) most of the tutorial exercises ask check/generate java for entityIMPL files

    Can someone tell me please the use of the above two java files and when we build them into our application


    Thank you

    Hello

    definition of entity class

    A class that extends directly or indirectly from oracle.jbo.server.EntityDefImpl. It stores metadata from runtime describing the purpose of the entity, including the attributes, events, validators, associations and properties. When it is instantiated, it describes all instances of the entity object class.

    A client can call methods to find information on the purpose of the entity, such as the names of attributes and types, source of the database and so on. There is an instance of the entity definition file XML entity class. You can use the object entity and Publisher wizard to generate the Java class to an entity object when you need custom create and find methods.

    This class is a good place for the methods group that are used by all instances of the entity object. For example, you can optionally modify the createDef method to use properties from another source (in addition to or instead of XML) when the entity definition is instantiated.

    If an entity object publishes or subscribes to an event (as specified in the pages of publication and subscription of the editor and the entity object Wizard), most of the code for the event is generated in the definition files of the entity objects that publish and subscribe. You can specify that this class extends a custom class (which must directly or indirectly extend the EntityDefImpl class and be in the classpath of the project); for example, you can do it if you want to reuse the code that has already been written or if your organization wants to customize the infrastructure of business components to meet needs.

  • with regard to the sliders

    Hi all

    which is the useful way to declare a cursor in the options below.

    1 cursor c is select * PGE (loop c, open, close).
    2. for i in (select * from emp).

    Please explain to this topic.

    Hello

    It depends on your condition.

    The first is widely used when dealing with packages or lengthy procedures or functions, where in you declare the cursor in the Declaration section and open and close as you like. But a precaution that should be taken if you open it for the second time, then you must check if the curcor is open or close before reopening. With the help of all others % ISOPEN attribute.
    Here, if you use the cursor for loop

    i.e cursor c is select & from emp;
    for r in c loop
    ...
    end loop;
    

    Then when the loop ends, the cursor is closed for you. So you can reopen.
    This method is widely used.

    The second is inline cursor is used when the cursor is not recalled in the block.

  • With regard to the creation of an Instance

    Hello
    I have a "FilterApplications" process which consists of a series of automatic activities. I have deployed the process in Enterprise Server. Now, I imported the PAPI WS in SOAP UI, when I'm trying to create instances through the processCreateInstance method (PAPI WS), I get the following error:-

    < xmlns:S s: Envelope = 'http://schemas.xmlsoap.org/soap/envelope/' >
    < Body >
    < S:Fault xmlns:ns4 = 'http://www.w3.org/2003/05/soap-envelope' >

    Details: process: ' / FilterApplications' is not deployed, it is inadvisable.
    the engine where it is deployed is not running or the user doesn't have permission to access to the process.
    Same I created the required participant to connect to PAPI WS using SOAP UI.

    But if the process contains any role, the (processCreateInstance) method above is able to create the instance for the process by using PAPI WS in SOAP UI.

    Can anyone suggest what is the problem here?

    Thank you
    Abhishek

    Yes - this is the designed behavior.

    The idea is that your logic of PAPI-WS is not able to create an instance, unless the user for authentication used in your logic has been assigned to a role in the process. This also prevents you to retrieve a list of instances of a filter unless your user id is assigned at least one role in the process.

    Hi Julie,.

    Thanks for posting your question in the Microsoft Community forums.

    I'm sorry to know that you can not upgrade to Windows 8.1. Let me help you with the question.

    What is the exact full error message that you receive?

    It seems that some system files are corrupted or computer infected by a virus. I suggest you follow these methods and see if it helps:

    Method 1:

    First, run us a virus scanner.

    Performs a search using the Microsoft safety scanner.
    http://www.Microsoft.com/security/scanner/en-us/default.aspx

    Important: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.
    The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss.

    Method 2:

    Scan the System File Checker (SFC) and then try to download the programs. Scan SFC replaces the system corrupted files with the original version of the Windows files on the computer.  Now, you can switch to Windows 8.1

    Use the System File Checker tool to troubleshoot missing or corrupted system files on Windows on Windows 8

    Let us know if it helps. If you have any other questions, we will be happy to help you.
