Concept of materialized views in Data Warehouse creation?

• Helps the management of records in the "VM and Templates view" as well as the view of data warehouses

  All,

  I have 2 questions.

  (1) in the 'view of VM and models', we have organized our virtual center of demand for the two years.  However, there are still many persistent VM in the folder root from this point of view.  How can I export the virtual machine from this point of view only and exclude the virtual machine already in a subfolder.

  For example, I have VM in APP1 and APP2 APP3 records.  However, there are still hundreds of virtual machines to the root.  When I try to view the virtual machine in the root folder, I get a list of everything, including the virtual machine in APP1 and APP2 APP3 records.

  (2) according to the data center, I have hundreds of data stores.  How can I make a list of people (about 200) and move them to a folder in this point of view.

  For example, I have 100 stores of data that are specific to the exchange environment.  I would like to move all of those in an Exchange_LUN folder so that I can set different alarm setpoints.

  All your data warehouses and folders have names unqiue, try the following

  $currentDir = pwd
  cd vmstores:
  Import-Csv -Path "C:\MyFile.csv" | %{
      $tgtFolder = Get-Folder -Name $_.Folder
      $ds = Get-Datastore -Name $_.Datastore
      $dsMoRef = @($ds.extensiondata.MoRef)
      $tgtFolder.ExtensionData.MoveIntoFolder($dsMoRef)
  }
  cd $currentDir
  

• How can I partition logical volume from 5.5 TB Raid on a ML350 G6 server for ESX data warehouse creation

  Today, we received a new ML350 G6 server. It has 8 hard disks of size 1 TB each.i have created a volume unique raid 6 and raid is 5.5 TB usable for the logical unit space. The server starts with a picture of ESXi 3.5 on a USB key provided by HP with the server. When I login and checking configuration& gt; stroage adapters& gt; pi400 Smart array for physical disk controller, I couldn't see any disk. I know that ESX will not support the volume size more than 2 C.T.

  I don't want to create a raid volume children (example two raid 6 volumes with 4 hard drives), because it will reduce the amount of disk space, I can use.

  Is it possible to create 3 partitions on this volume 5.5 TB raid with the configs below?. All the tools that everyone knows that I can use to create partitions? I tried GPARTED, but it doesn't work

  LUN 0-2 TO

  1-2 TO LUN

  LUN 2-1, 5 TB

  You cannot have a drive that is larger than 2 TB.

  Create multiple logical disks, not different partitions.

• Difference between the table and Materialized View

  Is there an advantage outside automatic synchronization (founded refresh selected type) using Materialized View?

  I came across this question as table and MV both store values, and we can also update table using the code what is the need of MV? Why not create a table instead of MV with the same definition and same charly?

  I need some explanation to force someone to convince himself.

• Insert the data in materialized views at the Table

  Hello

  We have a problem in which some incorrect data has been loaded for tables.

• Creating folders in the view of data with powercli store

  Hello

  We try to automate some parts of a build script and we want to create a folder in the view of data warehouses to move all the local disk.  the only place that I can create a folder has been the point of view of Cluster, DataCenter and VM.  is there a way to do this?

  Thank you

  Matt

  This is a hidden folder named "datastore".

  You can do

  $dsHome = Get-Folder -Name datastoreNew-Folder -Name MyFolder -Location $dsHome
  

  Note that there is 1 folder "data store" by the data center.

  If you have more than 1 data center in your vCenter, you need to indicate what you want "datastore" folder from the data center.

  $dc = Get-Datacenter -Name DC$dsHome = Get-Folder -Name datastore -Location $dcNew-Folder -Name MyFolder -Location $dsHome
  

• Oracle Warehouse builder or materialized views

  I have a requirement as follows:
  
  Requirement:
  We must create a Reporting DB to be used for information and a transactional database will be in separate host. Fundamentally, he need to extract data from a set of transactional DB tables and move to the Reporting DB schema at adequate intervals.
  
  We may have to get a different column data in different tables and store it in a single table / several reports DB tables.
  
  
  Can someone whether to go with Oracle Warehouse builder or the materialized views for this offer please?

  The two are not exclusive. OWB is a tool for designing the data movement and implement updates to the warehouse.

  MVs are a tool integrated into the database in support of materialization of the current request to speed up some types of applications related to data that is availoable, perhaps after transport OWB.

  I explored a similar approach, using the following test case.

  It creates a table "MASTER_TABLE" containing 20,000 lines and a CLOB containing an XML fragment like this:

• Excluding views materialized to a data pump export

  Hello
  
  I use the Oracle11g 11.1 RAC on Linux version
  
  I am trying to remove a schema of data pump export materialized views. I used EXCLUDE = MATERIALIZED_VIEW in the
  settings file. The materialized view is not exported, but the table associated with the view is always exported. Does anyone know how to remove those?
  
  Thank you
  
  Richard

  You will need to specify the tables in the exclude parameter.

  EXCLUDE the = MATERIALIZED_VIEW would not exclude the paintings of masters associates.

  In a single parameter EXCLUDE specify:
  EXCLUDE THE = MATERIALIZED_VIEW, TABLE: IN "('EMP', 'DÉPARTEMENT')" "

• Refresh/update of the data in a materialized view

  Hello
  I have question about data in a materialized view, and how it is updated. I think Matt has all my dimension-ID and my (for my specialize needs) aggregated measures of my fact table. I used mat View Wizard to create my opinion - which works perfectly. But now I wonder if I should create some sort of mapping (?) or some kind of trigger to refresh the data in the view of mast. Or are updated automatically when I start my fact table mappings. I use OWB 11 GR 2

  MVs have properties for update - you a discount based on schedules or when dependent data are committed or manually.

• How to understand where are the data in a materialized view, coming from

  HI: when I run select NAME, OWNER of dba_mview_refresh_times, I see a number of materialized views. How can I find more information on this view it's source data and fields.

  Take a look at the column of the QUERY to the DBA_MVIEWS view.

• You can use Windows Explorer (in Windows XP) to view my files according to their DATE OF PUBLICATION (rather than the date of creation or modification).

  I have a lot of cuts in MY Documents. They are variously in format (TXT, WORD, and PDF). Using Windows Explorer, I know exactly how to display these documents based on their date of creation or update. But how to display these documents based on their release date.

  (1) there must be a way to set "date of publication" as a property of TXT, Word, and PDF files.

  (2) there must be a way to display in chronological order the files in Windows Explorer - not according to their creation or modification date, but according to their date of publication.

  Can someone please? Maybe someone write an essay with many historical sources can feel my pain. I was playing with MS Word properties and trying to create custom, attributes but so far I still did not understand how to format a) correctly a new attribute for b) search for this custom in Windows Explorer or the Publication Date attribute.

  In short, I want to see all my files, because they have been published so that I can have a "timeline of events" outcome of saved newspaper clippings.
   
  Rabindra

  Name/rename the files with numbers on the front of the file name; for example, 01-11-2009 - historicaldocument1.doc, 02-13-1957 - historicaldocument2.doc. There is no way for Windows can read the text of a file whether it refers to the great Chicago Fire what on such and such a date.

  If you are doing historical research, you can check on some forums/newsgroup user on your particular area to see if other people use the documents management software. It would be the best way to go. MS - MVP - Elephant Boy computers - don't panic!

• Moving all the newspapers and Materialized View at the schema level using the data pump in

  Hi Experts,
  
  Please help me on how I can exp/imp all materialized views andMV logs (as are some MVs) only the full scheme of other databases. I want to exclude everything else.
  
  Concerning
  -Samar-

  Using DBMS_METADATA. Create the following SQL script:

  SET FEEDBACK OFF

        IS
          SELECT  DBMS_METADATA.GET_DDL('MATERIALIZED_VIEW',MVIEW_NAME) DDL
            FROM  USER_MVIEWS;
  BEGIN
      DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'SQLTERMINATOR',TRUE);
      FOR V_REC IN V_MLOG_CUR LOOP

  Now, you can run this on the database. You may need to adjust the tablespace and storage clauses. Or you can add more DBMS_METADATA. SET_TRANSFORM_PARAM calls to C:\TEMP\MVIEW_GEN. SQL to force DBMS_METADATA not to include the tablespace or / and the terms of storage.
