• 'Command for incremental load' DAC contains @DAC_ *.

  Hi Experts,
  I work on 10.1.3.4.1 DAC and uses the OOB repository. The Informatica version 8.6.1.
  I came across several tasks with the additional orders and support is entered as @DAC__CMD.
  Can someone let me know what it does stand?
  
  Thank you

  You can watch note Metalink 973191.1 ID (see below). If it is useful, please check the response accordingly.

  Cause
  The 'Source Dimension loading", has the following definition:

  -Customer DAC > Design > tasks > load in the Source Dimension > order for incremental load = "@DAC_SOURCE_DIMENSION_INCREMENTAL."

  and

  -DAC Client > Design > tasks > load in the Source Dimension > order for full load = "@DAC_SOURCE_DIMENSION_FULL."

  instead of the actual names of the Informatica workflow.

  The CAD parameter is not substituted with the appropriate values in Informatica for ETL

  This is caused by the fact that ORDERS for FULL and INCREMENTAL fields in a task of DAC are not specific texts of database as described in the following bug:

  Bug 8760212 : FULL AND INCREMENTAL ORDERS SHOULD ALLOW DB SPECIFIC TEXTS
  Solution
  This problem has been resolved after you apply the hotfix 8760212

  The documentation says to apply the Patch 8760212 to DAC 10.1.3.4.1 according to the requirements of the systems and the Guide of platforms supported for Oracle Business Intelligence Data Warehouse Administration Console 10.1.3.4.1.

  However, Patch 8760212 has become obsolete, recently, in this platform and language. Please see the reason mentioned below on the "Patches and update" tab on My Oracle Support.

  Reason of Obsolescence
  Use rather cumulative Patch 10052370 .

  Note: The most recent replacement of this patch is 10052370. If you download Patch 8760212 because it is a sine qua non for another patch or group of hotfixes, you must check whether or not if the Patch 10052370 is appropriate as a condition before substitute before downloading.

• With regard to Incremental loading in owb 10.2

  Hello
  
  I need the incremental load process mapping.
  
  If anyone has the sample mapping please send me the .mdl mapping.
  
  It is very urgent.
  
  Thank you
  Vincent

  Hi Vincent

  A simple solution is to add a date for mapping input parameter and then connect that setting a filter input. This filter is also connected to the source table. The filter clause will say "where the data in the source table are superior to ." For the initial charge, you simply set the parameter to a date very far in the past. That would be enough for what you are after?

• Full and incremental backup files storage

  Hello

  As a result of a previous full backup of I photo catalog, I recently realized an incremental backup.

  By mistake the incremental files are in another folder as the backup files.

  Can I just move all the additional files to the folder that the full backup is in.

  Thank you

  Jim

  When I do another incremental backup, that too will have to be in another folder?

  Yes.

  Am I right in assuming that an incrremental backup copies all files that have been added to the photo library after the initial backup completes.

  Yes, it copies files recently added and modified.

  If this is the case can I delete previous incremental upward when I performed a new differential upward.

  Yes you can.

  If you start another incremental backup, it will ask you to point to the initial full backup, or the last incremental backup. Each incremental backup knows that the previous incremental backup is there is one.

  Should I must point rrestore upwards do I start from the last incremental and is that all I need d, o or I do restore a differential and a full save or vice versa?

  You should start by the last incremental backup, which will send you to the previous, previous... and so on until the original full backup is used.

  In addition,

  Assume that you have a monthly backup with 6 additional seals.

  You want to restore to the State after the third incremental backup. No problem, you stard with Inc. Nr 3, then full then 2, then 1.

• NAVE of Lightroom 4 files/D5100 - full preview image load dark

  Hi team,

  I shoot in raw (NEF) with a Nikon D5100 and I noticed that when the preview loads fully, it loads a lot darker that what shows to preview so only load it.  Does anyone know why this might be?  The image I see during the loading of the image in Lightroom is the picture I want to work with, not the blackened image that shows a preview of the full image.

  -photorobot2010

  The image you see during your photo loading LR is the JPEG that is embedded in the camera raw file. LR replaces it with its own insight that it restores from the raw data. You probably all active D-Lighting in the menu of your camera. This causes the image underexposed, and then augmented when the JPEG is created. LR ignores ADL, so you'd better put it on 'off '.

• Incremental loading of Source

  Hi gurus,
  
  I'm looking for a way to extract the incremental data from my source tables in Oracle.
  
  I designed an INF_CUST of Interface that loads data into my staging table STG_CUST table SRC_CUST of the source.
  
  This interface directly load the data.
  
  I want to design the interface in such a way that -
  
  The first time I run the interface must retrieve all the data from the source.
  
  Thereafter, every time that I should choose only new or updated rows.
  
  Table source SRC_CUST a last_update_date column and I need to recover data that has been updated after I ran my interface.

• ETL process for updating the vm details

  Hi all

  I need an overview of what follows. I have an existing script that evolved over time (original source WoodITWork.com - it's about time I let the world know what I thought...).

  The intention is to connect to 10 virtual centers, export a list of properties for the vm for each CV to 10 different csv files.

  Do I have to add, this is the name DNS and vm UUID, then help how to name each csv with the name of the virtual if possible.

  $VC = to connect-VIServer $VCServerName

  #$VMFolder = "workstations".

  $ExportFilePath = "C:\PS\Export-VMInfo.csv".

  $Report = @)

  #$VMs = get-file $VMFolder | Get - VM

  $VMs = get - VM

  $Datastores = get-Datastore. Select Name, Id

  $VMHosts = get-VMHost | Select Name, Parent

  {ForEach ($VM to $VMs)

  $VMView = $VM | Get-View

  $VMInfo = {} | Select VMName Powerstate, OS, IPAddress, Cluster, data store, NumCPU, MemMb, DiskGb, DiskFree, DiskUsed

  $VMInfo.VMName = $vm.name

  $VMInfo.Powerstate = $vm. PowerState

  $VMInfo.OS = $vm. Guest.OSFullName

  $VMInfo.IPAddress = $vm. Guest.IPAddress [0]

  $VMInfo.Cluster = $vm.host.Parent.Name

  $VMInfo.Datastore = ($Datastores | where {$_.}) ID-match (($vmview.)) Data store | Select - first 1) | Select the value). Value} | Select name). Name

  $VMInfo.NumCPU = $vm. NumCPU

  $VMInfo.MemMb = [math]: round (($vm.)) (MemoryMB), 2)

  $VMInfo.DiskGb = [math]: Round ((($vm.)) Hard drives | Measure-Object-CapacityKB property-sum). Summary * 1 k / 1 GB), 2)

  $VMInfo.DiskFree = [math]: Round ((($vm.)) Guest.Disks | Measure - Object - property FreeSpace-sum). Summary / 1 GB), 2)

  $VMInfo.DiskUsed = $VMInfo.DiskGb - $VMInfo.DiskFree

  $Report += $VMInfo

  }

  $Report = $Report | Sort-Object VMName

  IF ($Report - don't ' ') {}

  $report | Export-Csv $ExportFilePath - NoTypeInformation

  }

  The other question is if it is still the most effective way to use the data as the Victoria Cross 4 got 4000 + vm

  The following should include these new properties you requested.

  $VC = to connect-VIServer $VCServerName

  $ExportFilePath = "C:\PS\Export-VMInfo.csv".

  $Report = @)

  $VMs = get - VM

  $Datastores = get-Datastore. Select Name, Id

  $VMHosts = get-VMHost | Select Name, Parent

  {ForEach ($VM to $VMs)

  $VMView = $VM | Get-View

  $VMInfo = {} | Select VMName, vCenter, Uuid, DNS, Powerstate, OS, IPAddress, Cluster, data store, NumCPU, MemMb, DiskGb, DiskFree, DiskUsed

  $VMInfo.VMName = $vm.name

  $VMInfo.vCenter = $vm.client.ServerUri.Split('@') [1]

  $VMInfo.Uuid = $VMView.Config.Uuid

  $VMInfo.DNS = $vmView.Guest.HostName

  $VMInfo.Powerstate = $vm. PowerState

  $VMInfo.OS = $vm. Guest.OSFullName

  $VMInfo.IPAddress = $vm. Guest.IPAddress [0]

  $VMInfo.Cluster = $vm.host.Parent.Name

  $VMInfo.Datastore = ($Datastores | where {$_.}) ID-match (($vmview.)) Data store | Select - first 1) | Select the value). Value} | Select name). Name

  $VMInfo.NumCPU = $vm. NumCPU

  $VMInfo.MemMb = [math]: round (($vm.)) (MemoryMB), 2)

  $VMInfo.DiskGb = [math]: Round ((($vm.)) Hard drives | Measure-Object-CapacityKB property-sum). Summary * 1 k / 1 GB), 2)

  $VMInfo.DiskFree = [math]: Round ((($vm.)) Guest.Disks | Measure - Object - property FreeSpace-sum). Summary / 1 GB), 2)

  $VMInfo.DiskUsed = $VMInfo.DiskGb - $VMInfo.DiskFree

  $Report += $VMInfo

  }

  $Report = $Report | Sort-Object VMName

  If ($Report - don't ' ') {}

  $report | Export-Csv $ExportFilePath - NoTypeInformation

  }

  For a larger environment, it would be in any case more quickly opt for the solution of Get-View.

• DataLoad

  Hello
  
  We have a requirement where we want to update the data in the General Ledger during our period-end closing process (1 month 5 days o) in Essbase. What are the best practices in the market
  
  to achieve this. We don't use FDM, we have an ETL process using ODI that load data from Oracle EBS to Essbase. This process must be performed by users without participation
  
  o IT. Hyperion Planning11.1.1.3. Ideally, there should be a process that begins this process automatically when the book is updated.

  You should have a look at the options of CDC (change data capture) in ODI to capture any changes in your source database.

• Load with the incremental update of the IKM Oracle

  Hi Experts,

  According to my understanding, incremental load is that the new data (with insert append or load incremental (update/insert or merged with or without behavior SCD)).

  While peek into the code of the IKM KM here it is my understanding:

  Incremental update: given the PK defined in the target data store, that KM will check line by line and put insert/update (change data capture).

  Append: Blindly block for the table insertion target and any changed data will be captured. It will not truncate and insert so that to avoid duplicates in the data, have a PK defined in the target table, so whenever the duplicate data comes it can be prevented or go for CKMs.

  
  

  Now my doubt is,

  
  

  When you use the incremental km update: the scenario is I have an incremental load today, inserted for example 200000 files today and tomorrow other 200000 records added (may include updates of certain lines in the previous loaded 2,00,000 documents. Now it will scan 4,00,000 (yesterday + today) and seek changes, I mean to update or insert

  Because according to my understanding will treat this KM row by row all records (my understanding is correct?). If it reads each record and are looking for a change or not change it seems to me that his time and performance issues?  CDC is right approach in this scenario or the implementation of SDC on all columns in the table?

  
  

  Regarding the large number of records coming daily, updated incremental if IKM checking all records for update or insert or no change, in my opinion, this isn't a performance wise and time to compare source and target value. This KM eliminate comparing itself the Chronogram of the source to target those who does not charge any change in any of the previous column value?

  
  

  
  Sorry if this is a silly question. Just trying to figure which can be better charge strategy, especially when I have millions of records entering source daily.

  
  

  SSX I remember ealier JeromeFr our expert member in the community, said Partioned Exchange to treat only to process the given month data when you manage tables partitioned at the database level.

  Hi ASP_007,

  Charge, as opposed to full reload, does indeed only new (and possibly changed) data. There are 3 main ways to do this:

  • Set up a filter in your mapping interface/load only the data including the upper date to a variable (which holds the last loading date).
  • Use the framework of the CDC in ODI. There are several JKMs. The solution optimal is probably the Golden Gate, one, but you must purchase this additional license. mRainey wrote about this several times: http://www.rittmanmead.com/2014/05/goldengate-odi-perfect-match-12c-1/
  • Retrieve all the data in the source and allow an incremental update of the IKM define what already exists.

  Of course, the first two still will take a little more time to develop, but it will be much faster in terms of performance because you treat data less.

  It is for the part "Extract", get data from the source.

  Now, you must know how to "integrate" into your target. There are different strategies as insert Append, incremental update, Type 2 SCD...

  • Indeed insert Append won't update. It will only insert lines. It is a good approach for a full charge, or for an additional charge when you want to insert data. There is an option in most of the IKMs Append (control) to truncate the table before inserting (or delete all the lines if you do not have the privileges to truncate).
  • Incremental update: there are different IKMs for this and some may have better performance than others depending on your environment. I recommend you to try a few and see which is more fast for you. For example ' IKM Oracle incremental update (MERGE) "could be faster than 'IKM Oracle incremental update. I personally often use a slightly modified version of ' IKM Oracle incremental update (MERGE) for Exadata ' to avoid using a work table (I$ _) and perform the merge directly into the target table. The last approach works well with the CDC when you know that all data are new or changed and needs to be treated.
  • SCD2: To maintain your dimensions needing SCD2 behavior.

  So in answer to your questions:

  Because according to my understanding will treat this KM row by row all records (my understanding is correct?). If it reads each record and are looking for a change or not change it seems to me that his time and performance issues?

  Some of the IKMs will do it line by line, others will do it based on a game. This is why it is important to check what he does and he spots.

  CDC is right approach in this scenario or the implementation of SDC on all columns in the table?

  Yes certainly, you will have less data to be processed.

  Regarding the large number of records coming daily, updated incremental if IKM checking all records for update or insert or no change, in my opinion, this isn't a performance wise and time to compare source and target value. This KM eliminate comparing itself the Chronogram of the source to target those who does not charge any change in any of the previous column value?

  Yes, by using ' IKM Oracle incremental update (MERGE) for Exadata ' with the strategy of 'NONE '. This means that he will not try to see the rows from the source is already in the target.

  PS; I am remember ealier JeromeFr our expert member in the community, said Partioned Exchange to treat only to process the given month data when you manage tables partitioned at the database level.

  It is a good approach when you want to reload an entire partition (if you have a monthly charge in a monthly partition or a daily load in a daily score for example). It is easier to set up to load the new lines only. But if you need to update things in the source, you can use incremental update strategy on an intermediate table that contains the same data that your partition and then create the swap partition in a further step.

  Thanks for the mention.

  Be sure to close your other discussions.

  It will be useful.

  Kind regards
