• Cube ASO with BSO Partition as a target

  Hello
  
  Can someone please explain to me the following because I'm not able to understand, after reading various articles and other documents Essbase
  
  What is the actual use to have a partition BSO Transparent (target) of a cube ASO (source)?
  
  Exactly how does the Write-Back functionality if I have a transparent wall BSO (target) of a cube ASO (source)?
  
  And finally, in that companies first scenario would implement a transparent wall BSO (target) of a cube ASO (source)?
  
  Your help is very appreciated.
  
  Thank you

  I will explain a simple business case that we use in our systems.
  Actual expenditures are loaded into the ASO cube at the day level.
  In the BSO cube, we will maintain budget and forecasts at the level of the month.
  The two strokes are synchronized except the time dimension.
  Transperent partition is created from ASO (source) to OSI (target) for actual expenditures and months.
  This will help the BSO users by reading the actulas comparison purposes when they do adjustemnts budget and the forecas.
  Here there no problem in writing to the budget and forecast in the BSO cube and users are not supposed to do any writing to the actual numbers.

• Problem: one of the members of the child is not aggregate to the Parent cube ASO

  Problem: one of the members of the child is not aggregate to the Parent cube ASO

  Here is the hierarchical structure of the ASO.

  At ~ Labelonly

  b + shared member

  C + Shared member

  Aggregated Expectated result: A = 150 USD

  b contribution 100 USD

  C contribution 50 USD

  But total shwoing associate for A is currently 100 instead of 150 USD.

  Then, I tried to remove members of 'b' then no value does show for A which means Member 'c' does not participate in the aggregation.

  Please let us know if anyone is facing the similar problem

  One member of the label will always be equal to the value of the first child.  You need to remove to get a sum

• FX translation in cube ASO

  I heard that it is possible to perform translations of monetary dynamics via Member mdx formulas in a cube ASO, but so far I couldn't get much of what it is to work.

  I have a cube that contains a dimension of projects, a dimension of country among others, and a monetary Dimension, as well as the size attribute for project currency and currencies of the countries.

  Each country are marked with an attribute of the currency of the country in the form of the EUR, GBP, JPY, etc..

  Each project is marked with an attribute of currency project in EUR (P), (P), (P) JPY GBP, etc.

  The exchange rates are stored in the dimension of currency with the names of Member in form 1EUR, 1JPY, 1GBP, etc..

  We have a member of the reference currency in the monetary dimension, where all the raw data is loaded and to complicate things, income values are specified in the currency of the project and the cost values are specified in the currency of the country.

  I try to add a member of the "US Dollar" in the dimension of currency that dynamically converts revenue after costs depending on the currencies of countries attribute and the attribute project currency using corresponding exchange rates.

  Any ideas?

  Sorry - no - what I wanted to create a monetary dimension as follows:

  Currency

  Local

  curr1_loc data will be loaded to these

  curr2_loc

  ... several currencies other than the Euro and USD

  Euro_loc

  USD_Loc

  Convert

  USD

  Formula curr1_loc_Converted_to_USD on these

  Formula curr2_loc_Converted_to_USD on these

  ... several currencies other than the Euro and USD

  Formula Euro_loc_Converted_to_USD on these

  Formula of USD_Loc No. necessary here

  Euro

  Formula curr1_loc_Converted_to_Euro on these

  Formula curr2_loc_Converted_to_Euro on these

  ... several currencies other than the Euro and USD

  Formula of Euro_loc No. necessary here

  Formula USD_Loc_Converted_to_Euro on these

  Add more currencies converted according to the needs.

• Load of FDM data in cube ASO

  Hello
  
  It is possible to load data from cubes ASO in 11.1.2.1 use FDM? I know that we cannot do in 11.1.1.3.
  Please advice.
  
  Thank you.

  Hello

  Yet another workaround solution "doubtful" but could replicate you your outline of the ASO (members only) in a database of the OSB, set it as your target in FDM, but as you say never load the data to it and put something between the two.

  This would mean that you have to maintain the hierarchy in two places, but it overcome the need to validate your cards.

  I agree that we reach beyond the kingdoms here now so I think you need to find a way more 'standard' to achieve what you need.

  Good luck

• Partition relicated ASO

  Can I create partition replicated using ASO?

  Yes, you can create partiton repeated BSO (Source) ASO (target) cube from version 11.
  But ASO cannot be a source for the replicated partition.

• increase the 'size of the cache pending' of our cube ASO to capture whole database in memory?

  Happy new year everyone,

  We want to take full advantage of our 54 GB of free memory on our server Exalytics X 4.

  From this site, I read more in anticipation of the ASO cache size will reduce the disk i/o.

  The default / .dat file size of data from our database of the ASO is 9.9 GB with more 100 million cells entry level.

  We should increase the 'size of the cache in waiting"our ASO to 9.9 GB cube so that the entire .dat will be cached?

  Thank you.

  ===============

  PS. Here's what I found in ASO Tuning white paper, which seems to recommend 512 MB or 1 GB.

  ASO cache size has an effect on the performance of loading data. For

  small databases with cells of entry 2 million or less, the default

  ASO cache size to 32 MB is sufficient. For a larger database

  with 20 million cells, 64 or 128 MB of cache is more appropriate.

  A database with 1 billion cells or more, the size of the cache can

  be placed as high as 512 MB or 1 GB if memory permits.

  Put all of the memory base looks really cool, but my experience is that in most cases it is not necessary. In my experience, the benefit of the ASO cache decreases rapidly. Here's an example I wrote about running aggregations:

• Rebuild partition cubes

  It will be very useful if I can have a bit of information here.
  
  I made a cube partitioned on a particular level of a particular dimension (say, day of the date dimension level). While retaining the cube by using the dbms_cube.build procedure, I watched each and every partition of the cube is rebuilt and preserved for which there are in the dimension. It also keeps the partitions for which no updates/inserts took place in my fact table (on which the cube is built). This behavior is expected because the holding time is unnecessarily very high (in the case of a single records in my table of facts, but the date dimension is to have 2 years of conservation)?
  
  The cube is actually built on a progressive vision of the fact table based on the time of update. I use mechanism of full refresh for dimensions and quickly resolve the mechanism of cube. AWM version is 11.1.0.7A and Oracle 11.1.0.7 database.
  
  Any response will be appreciated.
  Thanking in advance.

  The behavior you describe is planned. Specifically, if you run a "quickly resolve", then the server will reload each partition in the cube, whether or not it has changed data. What I am less clear, since you don't give enough details, is to know if the aggregation (aka SOLVE) fires in each partition.

  There are many tricks that you can play to reduce the amount of work done by an accumulation, but the precise approach will depend on the amount of data you want to load every time. If you load a relatively small amount of data each time, and especially if it corresponds to only one or two partitions, then you could try the following.

  exec dbms_cube.build('my_cube using (load serial, solve)', parallelism=>2, add_dimensions=>false)
  

  The keyword SERIES tells the server to load all the mapped both table values (i.e. no partition). It's a great victory, if your table contains data for only a few partitions or if she has very few lines. SOLVE step will be parallelized, but will fire only for scores changed by loading step. Of course, you must set the parallelism to the desired level. If only one partition will be affected, you can choose the parallelism = 0.

• Sorting of columns when my data source is a Cube ASO of essbase

  I need to sort columns of information OBIEE how, because OBIEE is sort by alphabetical order. We have sucesfully reach to order the columns when the data source is a cube of essbase block storage but does not work for a cube storage global essbase (ASO)
  
  Anyone have expercie on how to fix this?
  
  See you soon

  I don't think that your type of Cube will make a differenct in sorting. Default with Essbase OBIEE sorts columns alphabetically.

  The best way is to create a logical column with a logic that mimics the normal sort and use this logical column in the RPD "column sort order.

  For example if you need to sort the months while I was doing was to write a CASE statement and assigned to some of these months as they will be in ascending order and I used this column in the column logic month 'Sort order' present in the properties of the column.

  Months when "jan" then 100 when February then when 101 mar then 102... When end of December then 110 112 else

  It may be useful

• Calculate the dimensions of the Cube ASO in 7.1.2

  Hi all
  
  Please let me know how to find the size of the ASO Cube in Essbase 7.1.2.
  One of the ASO My cubes contains 8 dimensions and about 75,000 members.
  In application folder .otl, .dat, .app, .apb .rul files are there.
  And the size of all these files from 111 MB only. (My assumption was the size of cube is the result of the addition of all these file size)
  I missed whatever it is to calculate the size of the cube.
  
  I heard that the size of the cube would be in the UK.
  
  Thank you
  Alain

  You can either take the full directory under the essbase\app\yourapp folder structure size
  It would be pretty much the same that you add up all the files .dat and .otl

  See you soon

• Question of another hierarchy cube ASO

  Hi all
  
  IAM trying to build one hierarchy of another cube of time dimension ASO
  
  Hierarchy is as below
  
  Date
  -> years
  -> Qtrs
  -> month
  -> Days(01-01-2010)
  
  For example:
  
  Date (GEN 1)
  -> 2010 (Gen2)
  -> Qtr1 (Gen3)
  -> jan (Gen4)
  -> 01/01/2010 (Gen5)
  -> 02/01/2010 (Gen5)
  
  IAM another hierarchy of construction for the weekend that our company need to analyse certain measures on a weekly fashion
  
  
  IAM trying to build this way
  
  Date (GEN 1)
  -> 2010 (Gen2)
  -> week_end_sat (Gen2)
  -> 02/01/2010 (Gen3)
  -> 09/01/2010 (Gen3)
  
  
  
  I did test
  
  (1) I tried to built a shared Gen5 member and I did and when I tried to build another hierarchy to knowledge of generation different Gen3 iam facing problems with the rule files
  
  Unable to build a rules file with correct size of IAM properties
  
  
  Please let me know if you have any idea it would be great.
  
  
  Thank you
  Riou

  You need several hierarchies enabled. 2010 weekend Sam must be stored separate hierarchies.

  BTW - it would be easier and I think on a higher functional level if you have used a dim attribute instead of an alt roll up, but your choice.

• Loading 2 alias of a member in a cube ASO by rule in essbase file

  Hi all
  I have a request from ASO. We are members of dimension using dimension build rule filesto load.
  Currently I am only alias default load using reference of parent-child. (Parent0 Child0 alias0)
  
  My problem is that I want to load two aliases. (1.default, 2.Default1). How is that possible?
  What should be the structure of my flat file for loading the metadata?
  
  
  Thanks in advance...

  In a rule of load, you describe what table alias must be used. If you want to load more than one alias, then I suggest a format such as

  Parent, child, alias aliases1, Alias2

  You would have two first rules would ignore alias 2 during construction of the dimension and the second he would ignore Alias 1 load. Each would be the table of the correct alias to load. (ISO the global settings of the Dimension tab build properties dialogue box).

• ASO Transparent Partition Mapping for large contour

  Hi guys,.
  
  I play a bit with a big cube ASO.
  I am trying to create a transparent wall with a mapping of each Member Lvl0 a dimension of the source cube for each Member of Lvl0 (with a different name in the source) in the target cube. In addition to Lvl0 members all members have the same name.
  So far so good - works like a charm in theory (the dimension whose members are mapped are identical, except the name of Lvl0 members).
  
  Now to my problem: I want to do this (mapping) for about 2.5 mio stored Lvl0 members (I know, crazy isn't).
  Is there anyone of you experience for such an amout of mapped members? Is it still possible?
  
  I guess in theory it would be possible to do. However, I don't want to manually type in 2.5 mio mappings.
  I reached with MaxL size maximum possible statement (not really surprising... the file that I have to go to MaxL is 170 MB).
  I thought to divide it into several MaxL commands, but I don't know any command MaxL add a mapping to an already existing partition of transparent without changing the other mappings of the partition or recreate the partition.
  
  Anyone of you an idea?
  
  Essbase version is 11.1.1.3.

  An ideal solution that would be perfect, but is not taken in charge by Essbase:
  Build the cube with anonymized Lvl0 members having a table alias where membername cleartext is stored. Users outside our country don't you access this table alias, only users inside our country access to it. But as already said, this is not supported by Essbase.

  So if someone could think of another solution or would be able to offer a solution for transparent partition mapping, it would be highly appreciated.

  Thank you
  Thomas

  Now I can't think this completely, but in theory, you could do the "ideal solution". As you say, create the cube with lvl0 anonymised in the source and then create two cubes of target, we have the anonymous names and the other the table alias with company names... Would this be possible? As the two cubes of target would have the anonymous names there would be no partition map, but would require the cube that contains the data to be mapped once clear to anonymized. Thoughts?

• Partitioning of the ASO

  Hello
  We are running essbase version 11.1.1.1.3. My question - you can partition 2 cubes ASO? Which means, can you have 2 cubes ASO, being a source and the other a target? (Sorry for the simplistic example). The partition Wizard does not seem to allow it to
  Thanks as always

  Yes, you can do it if it's transparent/related, have a look at the following table:-http://download.oracle.com/docs/cd/E12825_01/epm.111/esb_dbag/dotprtde.htm#dotprtde_53
  It highlights the types of partitioning combinations that can be used.

  See you soon

• Access to several cubes Essbase ASO through a single cube

  Hello
  I have 10 cubes ASO and each cube contains data of one day (one day contains lines of facts about 30 million). Is there a feature in Essbase that combines all these cubes ((like a virtual cube)? Or can we do this task using the BI server. If we are unable to combine these cube then what is the best method I could use to query all 10 cubes at a time?
  Thank you in advance.
  
  Concerning
  
  Chandra

  It sounds like you could have 10 cubes ASO partitioned seamlessly to a cube of target (OSB?) users could connect you to receive the combined data. It makes life easier if they are all the same size. The target would have every day and each source cube could be partitioned by day.
