Dimensions and Cubes Process OK / database 'Process Full' fails

Hello,
I am having trouble processing SSAS database (SQL 2008R2).
Within BIDS environment I can process all dimensions and two cubes - no problem. But when I try to process the database (Process Full – Sequential/ All in one transaction), I keep getting errors about one specific dimension (however the very same dimension
is processed separately just fine).
Any ideas why this would happen?
Thanks,
Lana

Thanks so much for all your replies! Your help is greatly appreciated

Here is the error message I am getting (it is the same for bunch of other attributes of the same dimension called
Item):
Errors in the OLAP storage engine: An error occurred while the dimension, with the ID of 'Item', Name of 'Item' was being processed.
Errors in the OLAP storage engine: An error occurred while the 'Product Group' attribute of the 'Item' dimension from the 'InvCube' database was being processed.
OLE DB error: OLE DB or ODBC error: Operation canceled; HY008.
Errors in the OLAP storage engine: A duplicate attribute key has been found when processing: Table: 'dbo_Item', Column: 'Colour', Value: ''. The attribute is 'Colour'.
Keep in mind that the Key for this dimension is called ItemID and there are no duplicates (I checked). Before processing the cube, I have dozens of procedures (within SSIS package that brings the data into DW) that are checking if all the
keys (FK columns on Fact table) exist within dim tables (PK columns). I also do not allow NULLs or blanks for the dim keys within Fact tables, I replace them with
special “DimName-000” Keys that, again, exist within dim tables.
What I am trying to figure out… why I can process Item dimension just fine on its own (I also process all the other dimensions OK), after that I can process both cubes that are using this (and other) dimension(s) … and I can browse the cubes, getting breakdown
by Item / Colour / Product Group, etc... So, everything seems to work perfectly. However, when I try to process the whole database (with all previously processed dimensions and both cubes - there are only two cubes for now, to make is simple), the process
fails, giving me an error about duplicate attribute key for this specific Item dimension.
Any thoughts?
Thanks again!

OWB 11.2.0.1 dimension and cube operators + ODBC target database

Hi,
We are considering using OWB to populate a netezza data mart making use of the dimension and cube operators.
Could we use OWB for this/is it supported in this manner or do we need to use another ETL tool/workaround.
Understand OWB supports ODBC as target.
Any advice much appreciated.
Thanks

Hi
You can have ODBC targets but the cube/dim operators use MERGE loading type so its not a tested/supported case using the operators with Netezza. It has been optimized for Oracle.

How to import SH Sample Dimensions and Cubes with OWB Client

Hi, is there a functionality to import the Dimensions and Cubes from the sample to reuse and manipulate them within the OWB Client?
I can add Dimensions in the Enterprise Manager but mapping should be difficult- right?
Specs: DB 10g rel2, OWB 10.1.0.4

dimension - either define a table on your own, or use the data modeler and physically define a new dimension.
Cube - same as above.
as for levels and hierarchies, this can also be done in the data modeler. You can specify keys, levels, attributes, measures...all that stuff for dims and facts. There many tabs on the lower half of the dimension modeler screen that control this.
Check out the oracle by examples for easy tutorials.

Using dimension and cube operator

hi
I am facing problem in using this dimension and cube operator..
Actually I want to create a sales data with dimensions as time,customer and product
After creating a dimension in owb I get a table created attached with it same is the case with cube operator
so where should I store my measures in the cube or the table created and where to store the data about dimensions in the table created.
and finally how to use them in mapping to retrieve the data stored
Thanks

It sounds like you are not getting any matching keys for loading into the cube.
Do you have a time dimension created by OWB in the cube? The key used by the cube operator for an OWB time dimension is a formatted number. The time dimension keys are stored as follows;
Day Level - YYYYMMDD
Month Level - YYYYMM
Week Level - YYYYWW
Quarter - YYYYQ
Year - YYYY
If you have a source that has a SQL date datatype for example and want to construct the key for a cube's time dimension at the day level something like the following expression can be used to construct the time reference from a SQL date...
to_number(to_char( time_key, 'YYYYMMDD'))
It may not be this but just a thought.

Can CWM2 API creating dimensions and cube reference a view

Can CWM2 API creating dimensions and cube reference a view instead of a table.
Can the following API reference a view instead of table
For creating dimensions
CWM2_OLAP_TABLE_MAP.MAP_DIMTBL_HIERLEVEL
CWM2_OLAP_TABLE_MAP.MAP_DIMTBL_HIERLEVELATTR
For creating cubes
CWM2_OLAP_TABLE_MAP.MAP_FACTTBL_LEVELKEY
CWM2_OLAP_TABLE_MAP.MAP_FACTTBL_MEASURE

Hi!
Yes!
And I am using views sometimes.
I am reading at this moment also the following...
maybe someone can explain me this sentence...
MULTIPLE FACT TABLES:
"The CWM2 APIs also support multiple fact tables per cube. In this case, the data
associated with a given combinations of hierarchies can be stored in a separate fact
table. All the fact tables associated with a cube must have the same column
structure."
I get a fetch error message..'cause of this.
What does it mean by "the same column
structure" ???

Building Dimensions and Cubes in 11.1

Hi Experts,
Can anyone provide me a weblink or atleast steps as to how to create a Dimensions and Cubes in OWB 11.1.
For practice purpose i am accessing HR User. In there i have selected Locations and Countries table and is using it to create the Place_Dim (Place Dimension)
Issues:
1. What are Levels and Heirarchiies
(In ROLAP its asking me to use the surrogate Key i both the levels)
2. It is asking me to bound it to table or view. I have never seen any help regarding in bounding and out bounding in the tool.
Please help.
Regards,
Ravi Remje

Many Thanks Dave for your help. The links are very helpfull.
I have a silly doubt in my mind. Kindly apologize for my dumbness.
Concerns:
I went through the OWB tool and came to the conclusion that the DIMENSIONS and CUBES are logical object. However, if i want to use it as a Physical table, is it any way as in how we can use the simple tables as different types of dimensions and facts by changing their loading type. Is it any possible way to implement the same feature for DIMENSION and CUBE objects. I dont want them to be used as views but as a table.
Please help.
Regards,
Ravi Remje

Cannot find object after creating dimension and cube.

I need to develop a project using olap api to get olap data.
My db release is 10.1.0.2, owb is 10.1.0.4.
After i create dimension and cube in owb, I cannot find any object i have created in owb. Except that in OEM, after i click the button dimension, there comes an message as that the dimension does not have complete metadata or was created by old release and OEM will create a metadata for it. After that, I can find the dimension in AWM and get the imformation using olap api.
However, there is no measure button in OEM, I cannot find the measures in measure folder. So that i cannot get the information of the MdmMeasureDimension using olap api.
Can somebody help me with this issue? Thanks!

With OWB 10.1 and prior releases to get OLAP metadata for a dimension or cube you must have used the OWB transfer wizard to deploy the OLAP metadata. This bridge basically creates and executes a script with all of the CWM calls to create the OLAP dimension and cube metadata.
When you deployed the dimension from OWB in 10.1 it only created the 'create dimension DDL' for the object.

How to change column names in dimension and cube views?

whenever AWM creates a view on a dimension or cube, it creates columns for long and short description with full name
forexanmpel, it creates like
CREATE OR REPLACE VIEW OLAPTRAIN.CHANNEL_VIEW
AS
SELECT
"DIM_KEY",
"LEVEL_NAME",
"MEMBER_TYPE",
"DIM_ORDER",
"LONG_DESCRIPTION",
"SHORT_DESCRIPTION",
"ALL_CHANNELS_LONG_DESCRI",
"ALL_CHANNELS_SHORT_DESCR",
"CLASS_LONG_DESCRIPTION",
"CLASS_SHORT_DESCRIPTION",
"CHANNEL_LONG_DESCRIPTION",
"CHANNEL_SHORT_DESCRIPTIO",
"CHANNEL_TYPE",
"CHANNEL_CHANNEL_TYPE",
"CHANNEL_ALL_CHANNELS_ID",
"CHANNEL_CLASS_ID",
"CHANNEL_CHANNEL_ID"
FROM TABLE(CUBE_TABLE('"OLAPTRAIN"."CHANNEL"') );
what is the way to customize the column name? for example for class level, how can we say insterad of long_description and short_description, use LONG and SHORT simply?
i also see the size of long and short descriptions are set to varchar2(60) and varchar2(20), is there a way to change that for each level in AWM?
Thanks

Hi there,
I don't think there is a way to control the column names within the OLAP product itself, but if this is something you really want to do, have you tried creating your own views?
As you can see, the syntax is pretty simple
Thanks,

How to get DIMENSION and CUBE data into JDeveloper???

i have build cube and dimension using oracle analytical workspace manager (AWM),
how i can get the cube and dimension data using jdeveloper 11gR2??
does anybody know?
any extension? or what??

The simplest thing is to use JDBC (java.sql package) to access the cube and dimension views through SQL. Something like this (with appropriate error handling).
String sql = "SELECT dim_key FROM product_view";
Statement statement = connection.createStatement();
ResultSet rs = statement.executeQuery(sql);
while (rs.next())
// Process row here
rs.close();
statement.close(); If your requirements are more complicated or you feel adventurous, then you can use the Java OLAP API. This is the code used by the data viewer in AWM. (Look for olap_api.jar in your database installation -- olap\api\lib\olap_api.jar my windows instance.)

Process dimensions and Applications after Restore

We are using BPC 7.0MS. We need to process dimensions and Applications after the database restore in case of any Optimization failures. It takes around 3 hours for us to do this process. Can we skip the BPC process by taking backup of Database and SSAS and restoring them in case of any failures?
Thanks
Raj

Hi Raj,
you can try but remeber that after the restore you must execute a "modifiy application" for all your applications so maybe you'll not gain time.
Kind regards

Are fact tables and cubes same in OWB?

Dear all
A simple question. How can I create a star schema (that is, with a fact table and dimensions) using OWB?
OWB has options to create cubes, but as per my understanding a cube is not a fact table.
Cube contains pre-computed data where as fact table contains normal data with references to dimensions.
Please correct me if I am wrong.
thanks in advance

These are just different levels of abstraction.
"Cube" is the highest level of abstraction referring to the overall package of data.
"Star schema" is how cubes are modelled showing the relationships from a fact entity to the dimension entities.
Relational and OLAP are different methods of physical implementation.
In OWB, to promote sharing of dimensions across cubes to avoid inconsistency the idea is you define and build the dimensions independently. Then you define the "cubes" as measures and references to the dimensions. When you build the "cube" you pass in business identifiers from the source data which OWB will use to link the measures to the applicable dimension data. Due to the wonders of inner joins anyone reading the "cube" will only see dimension data related to the data in that cube!
Using OWB you do not need to be concerned with the physical implementation when you use the dimension and cube operators as those operators know what to do.

Errors in the OLAP storage engine: An error occurred while processing the indexes for the partition of the measure group of the cube from the database.

Errors in the OLAP storage engine: An error occurred while processing the indexes for the partition of the measure group of the cube from the database.
I have dropped and recreated a fact table to refresh the data as the table is having identity columns. So not able to directly insert data. After that cube is throwing above error.
Please suggest.

Hi Md,
It hard to analyse the issue base on the limited information, Are there any error message on the log? Under C:\Program Files\Microsoft SQL Server\MSAS11.\OLAP\Log (this could be different for your server), there are 3 log files that are generated:
msmdrrv.log
FlightRecorderCurrent.trc
FightRecorderBack.trc
The msmdrrv.log simply points to the other two logs. There might be some detail information for this error. Please provide us the detail information about it, so that we can make further analysis.

Delete request in ODS and Cube from process chain

Hi Experts,
I have the next situation: I have a process that each month need to extract data with a selection criteria of fiscalperiod and fiscalyear, only I can maintain a data request with this selection. For this, I need a delete the old request when I am extracting new data with the same selection criteria, in ODS and Cube.
Is it possible?
Thank you very much for your collaboration.
Regards,
Jeysi

Hi Jeysi,
DSO works on 'Overwrite' principle.
You need to check your data source.(The images your data source sends).
Even if your updating the key figures using addition method, the data source will send you the correct images and correct delta to keep your DSO as a reflection of the latest image of your source system.
Hence you would not require to delete a request with the same selection in the DSO.
Moreover, if you have a cube at the downstream of the DSO, loading deltas from the DSO to cube would alone be sufficient and you would not need to use delete overlapping request.
However, if you are loading full request to the cube from the data source with the selections of fiscal year and fiscal period , then yes you do require delete overlapping selections.
In 3.x data flow, this was configured in infopackage in data target tab there is one column for automatic deletions, here you could set the conditions on which the overlapping request in the data target(cube) in this case should be deleted.
In process chain, you can use , delete overlapping request from the process chain.under application node, load process and post processing.(This can be configured for both infopackages and DTP's)
Hope this helps,
Regards,
Sunmit.

Our organization uses an Oracle database hosted on a Unix platform and one of our data processing outputs is a “stuffer” document that has a barcode, and Unix jobs automatically send the document to a printer.
Is there a way, or does Adobe have a product or solution, to create a PDF version of the document including the barcode, before it’s sent to a printer?

What format is the document that is printed? Or what technology is used to format the printer? There isn't a standard way of doing things in Unix.

Reading file and dump data into database using BPEL process

I have to read CSV files and insert data into database.. To achieve this, I have created asynchronous bpel process. Added Filed Adapter and associated it with Receive activity.. Added DB adapter and associated with Invoke activity. Total two receive activity are available in process, when tried to Test through EM, only first receive activity is completed, and waiting on second receive activity. Please suggest how to proceed with..
Thanks, Manoj.

Deepak, thank for your reply.. As per your suggestion I created BPEL composite with
template "Define Service Later". I followed below steps, please correct me if I am wrong/missing anything. Your help is highly appreciated...
Step 1-
Created File adapter and corresponding Receive Activity (checkbox create instance is checked) with input variable.
Step 2 - Then in composite.xml, dragged the
web service under "Exposed Services" and linked the web service with Bpel process.
Step 3 - Opened .bpel file and added the DB adapter with corresponding Invoke activity, created input variable. Web service is created of Type "Service" with existing WSDL(first option aginst WSDL URL).
and added Assign activity between receive and invoke activities.
Deployed the composite to server, when triedTest it
manually through EM, it is promting for input like "subElmArray Size", then I entered value as 1 with corresponding values for two elements and click on Test We Service button.. Ptocess is completing in error. The error is
