• Problem of type 2 SCD - does not not all valid records

  Hello
  
  I'm working on a mapping including a dimension of type 2 SCD. The loans for loading in the dimensione are ranked by date (asc). Essential changes, I want a story are changes when a user moves from one Department to the other.
  A sample of the records of entry looks like this
  
  Department-ID Dept_name User_ID, user_name effective_from
  49 sale 94 Andy 2010-05-26
  54 94 Andy 2010-07-10 marketing
  
  
  The dimension has a trigger on department_id.
  The mapping works fine when I hit the dimension with the folders one by one:
  1. run inserts the first record
  2 rund inserts the second recording
  
  result: I have 2 folders in my dimension with the correct values.
  
  If I want to insert two records in the same race of the mapping, only the first record appear in the dimension.
  
  No idea what I missed during the definition of the mapping?
  
  
  Thanks for your help

  Hi Vincent

  Do you use the slowly changing dimensions OWB? If so by setting the metadata on the dimensions and using the operator of dimension, it should work out of the box.

  If you build it from the ground upwards, here's an example with the documentation;
  http://OTN.Oracle.com/sample_code/products/warehouse/files/SCDWhitePaper.zip

  Also, there is an expert on the Oracle OWB wiki that works on the base tables:

• Create a join between a column of type DATE and DATETIME RPD

  Hello

  In my DR. I have a fact table with a DATE column, which also contains a component "hour". The physical layer shows this as a DATETIME column that to this DAY, I've changed since I'm only interested in the part of the date.

  When I join it an alias of my Date dimension, the generated sql physics is similar to:

  DIM_DATE. DATE = FACT_A.FINISH_DATE

  What I really want is:

  DIM_DATE. DATE = TRUNC (FACT_A.FINISH_DATE)

  
  

  How can I achieve this at the level of the RPD? Yes, I can add a new column to the table of DW with truncated value, but I want to know why even though I chose the DATE as the type of data to the RPD, the created join does not have a trunk.

  
  

  Thank you

  The physical layer shows this as a DATETIME column that to DATE, I have changed since I was only interested in the part of date.

  N ° bad idea. The physical layer of the RPD should show what the physical source. So if it isn't a DATE, don't pretend OBIEE is it. For the exact reason that you now - tap you are pregnant OBIEE to write some SQL magic to cast the data type, without even say things which is the original type. OBIEE will not interrogate the metadata in order to check the data types in the source, it will rely on what you tell it in the physical layer.

  How can I achieve this at the level of the RPD?

  You could use an inline view in the physical layer and make your trunc here I guess. Better, as you've already identified, is to store the date as a date if this is going to be a key column to reach.

  I want to know why even though I chose the DATE as the type of data to the RPD, the created join is not a trunk.

  See above. OBIEE does not know it is a DATETIME value, then why would he do a TRUNK?

• What type of Nat configuration?

  Hello, I am puzzled by this NAT type should I use for my PIX515E.

  Our network is a roommate, and we deal with, sites Web and multimedia.

  So on this basis, I am mistaken, that I should not use PAT?

  I assigned the external IP pointing to the internal IP address.

  Is that all I need to configure so that the inside can access outside?

  I have attached a diagram simple of what will look like the network.

  Ok.. If you do not want PAT went for a host or a subnet, you can use what is called exception NAT. for example, the commands:

  NAT (inside) 0-list of access no_nat

  Access-list no_nat x.x.x.0 255.255.255.0 allow one

  the above instructions will be NO pat inside hosts located on the beach of x.x.x.0 out.

  I hope that helps, ahhah plese do not forget to rate if you find the information provided on this forum useful

• What type of network configuration... Server DHCP .virtual rent to physical machine...

  Dear all,

  Scenario:

  1. VMware workstation 12 running on a high-end laptop computer.
  2. VMware workstation 12 hosts a domain controller and a domian joined the DHCP role running windows server 2012 R2.
  3. the laptop is connected to an 8 port hub. Hub is connected to 3 physical servers, these 3 servers need a DHCP lease
  virtual DHCP server.

  
  Network is "Host Only" what kind of network do on VMWare Workstation and the DHCP server. Please see an article/tutorial if possible

  Thank you for your time, effort and valuable suggestions.

  Hello

  Your DHCP server must be on a bridged network adapter, it does not work with 'host only '.

  Edit: to be clear, I mean the network in your VM DHCP settings, wouldn't "NAT" or 'host-only' but 'bridged '.

• 2 conflict with Oracle Dimension object of type of DDS

  Hello world.
  
  I have a little problem of understanding of the Oracle side objects and how to use it with type 2 SCD.
  
  Documentation says Oracle: there must be a relationship 1: n between a parent and child. A parent may have one or more children, but a child can have only one parent.
  
  Makes me think that if I, for example, a Department 1 and area 'A', this Department must ALWAYS map the same area, the area 'A' may have more than one Department, but one Department must map to the same area each time.
  
  This is a good example: Department 1 cards 'A' box each time
  Employee service area
  1 1
  2 1
  
  This is an incorrect example: Department 1 IS NOT MAPPED to the 'A' box each time
  Employee service area
  1 1
  2 1
  
  Documentation says Oracle: you should not create dimensions in any schema that does not fully meet the dimensional relationships. Incorrect results may be returned by queries otherwise.
  
  OK, but what can we do so actually exchange area of the Department?
  
  Type 2 of the CPC, we use the following technique:
  Employee ID Department area start end
  1 1 1 ONE 2010-01-01 2010-01-02
  2 1 1 B 2010-01-03 null
  
  Now we can see that type 2 SCD does not meet the requirements what ORACLE recommends the creation of objects of Dimension, I want to say Department 1 cards now in the former zone A and the new area B.
  
  Is this right?
  
  If anyone can clarify this? I think that a conflict occurs.
  
  Thank you.

  Hello

  Is this right?

  No, you're wrong. You mixed a relationship history and the attribute dimension hierarchy.
  Mapping for loading dimension SCD2 behavior depends on how you did implement Department and area entities in your dimension.
  as a general attributes of small size (EMPLOYEE) or as the higher levels in the dimension hierarchy.

  If you set Department and area as an EMPLOYEE-level attributes that the behavior of the algorithm of loading will be such as you described-
  This is because OWB does not know that the Department and the area attributes make up hierarchy.

  But when you define additional levels Department and area - OWB tries to solve conflicts on the hierarchy in a very simple way.
  for each child dimension value, choose single-parent with minimum key value business.
  In your case the loaded data will be:

  Employee ID Department area start end
  1 1 1 ONE 2010-01-01 2010-01-02
  2-1-1 to 2010-01-03 null

  Since 10.2.0.4 patches group there is also based on hierarchy Versioning (if configured for the level of version control also contains EFFECTIVE_DATE, corresponding columns).

• SCD type 2 in OBIEE

  Hello
  
  I am relatively new to OBIEE and try to implement the change slow type of dimension 2 - that is to say, to find the correct record in the customer (A_FICC_ACCOUNT) dimension based on the date of the transaction in the fact (A_FICC_PROFITABILITY) table. The customer dimension has two time stamps (start_effective_date, end_effective_date), where end_effective_date will be null for most recent record.
  
  So far I have configured it as a complex join in the physical layer, as follows:
  
  A_FICC_ACCOUNT. ACCOUNT_ID = A_FICC_PROFITABILITY. ACCOUNT_ID
  AND
  (
  A_FICC_PROFITABILITY. DAYID > = A_FICC_ACCOUNT. START_EFFECTIVE_DATE AND A_FICC_PROFITABILITY. DAYID < A_FICC_ACCOUNT. END_EFFECTIVE_DATE
  OR
  A_FICC_PROFITABILITY. DAYID > = A_FICC_ACCOUNT. START_EFFECTIVE_DATE AND A_FICC_ACCOUNT. END_EFFECTIVE_DATE IS NULL
  )
  
  When I run a report in response, the generated SQL code is:
  
  Select distinct T2327. YEARCAPTION C1,
  T13994. SHORT_NAME C2,
  T13994. RANK_W12 as c3,
  T13994. RANK_W52 as c4,
  T2327. YEARID like c5
  Of
  DIM_FICC_ACCOUNT T13994 / * A_FICC_ACCOUNT * /,.
  DIM_TIME T2327 / * A_FICC_TIME * /,.
  FACT_FICC_PROFITABILITY T13406 / * A_FICC_PROFITABILITY * /.
  where (T2327. SKEY = T13406. TIME_ID and T13406. ACCOUNT_ID = T13994. Account_id and T13994. SHORT_NAME = 'PETEROLA' and (T13406. DAYID < T13994. END_EFFECTIVE_DATE or T13994. END_EFFECTIVE_DATE is null) and T13406. DAYID > = T13994. START_EFFECTIVE_DATE)
  order by c2, c3, c4, c5
  
  Ran directly against the database (Oracle) by using a client, it gives significant results according to the historical changes in the dimension. (see attached screenshot). In the responses, however, the results are not correct (see attached screenshot).
  
  http://DL.dropbox.com/u/3345113/output.jpg
  
  Advice on what could be wrong would be greatly appreciated.
  
  Best regards

  Magnus,

  As mentioned customer dimension (A_FICC_ACCOUNT) is a type 2 SCD, which is the primary key in this table? I don't think it's the only argument ACCOUNT_ID.
  Usually there is a surrogate key to keep track of any changes, so it's on this surrogate key is a join with a fact table and apply a date filter end_effective has the null value should produce a correct result.

  If the scenario above is not true in your case, let me know the structure of the dimension table and made customers (only columns associated with customer dimension), with relation ship information please.

• Attributes of the update/load (nonkey elements) Dimension table

  Hello
  
  Is there a configuration change in DAC or Informatica where I choose to load all dimension during a load tables, regardless of a transaction in the fact table? I have observed that for all these accounts with no corresponding transactions are extracted, but fell to the time they reach the actual dimension table. So in the end goal of DWH, only these unique accounts are presented which have an associated transaction.
  
  I know that we can create a mapping to the in order to include some sort of a flag to DAC thing assuming that the corresponding made base table has also changed and then carry on the dimension data. But is there a simple alternative?
  
  For example, in the GL, we have an account dimension, which has a line details associated with the transaction for each account in the fact table. I just changed the name of the account from A to B. Any changes or updates to the entrance of the line in the FACT table. Now, I run an incremental load. Will be change (new account name) has recognized and more? OR it will bring only when associated with line changes too?
  
  Usually when the dollar amounts do not change, nobody cares, but in our case the customer wants. I googled widely understand incremental loading but cud not get a clear answer to this question. SCD2 plays a role any in this?
  
  Thank you
  Dan

  If you want to capture the story on a field that is NOT before now, you can activate the Type 2 SCD and then add that field to the ETL in TYPE2 COL DIFF indicator that is used to add the entries of SCD Type 2 during the ETL. If the dimension is activated in Type 2, most of the work is done, it is not too difficult. However, be aware that this can lead to many more recordings volume performance and data to keep in mind that do you this.
