Large numbers for dimensional values creates problems due to rounding up
Using PostgreSQL, I get wrong result due to large numeric values on dimensions being rounded up. It seems that Mondrian (also internally) formats the number as scientific E notation, but with too low precision.
I create and populate the following table:
Next I make the following schema:
Then I run the following MDX:
The measure is empy, not 1 as expected:
Looking at the log, it seems that Mondrian fetches the dimension value (9123372036854775807), rounds it up to 9.1233720368547758E18, and then retrieves all rows where foo equals the rounded up value, not the exact value. Therefore no rows are found.
I create and populate the following table:
Code:
create table public.test (foo bigint, bar int);
insert into public.test values (9123372036854775807,1);
Code:
<Schema name="Test">
<Dimension name="Foo">
<Hierarchy hasAll="true">
<Table name="test" schema="public"/>
<Level name="Foo" column="foo" type="Numeric">
</Level>
</Hierarchy>
</Dimension>
<Cube name="Test">
<Table name="test" schema="public"/>
<DimensionUsage name="Foo" source="Foo"/>
<Measure name="Bar" column="bar" aggregator="sum"/>
</Cube>
</Schema>
Code:
SELECT
[Foo].[Foo].MEMBERS ON COLUMNS
,[Measures].[Bar] ON ROWS
FROM [Test]
[Foo].[9.1233720368547758E18] | |
[Measures].[Bar] |

Need help on 837 file format loading
Hello Friends,
Any one knows how to load 837 file format into Oracle database using Data integration tool(Kettle). 837 file is a health care domain file where all the hospitals uses to generate the Billing information. If any knows please help me out here. As of now we are depended on the JAVA coding to load this file and want to migrate this into the ETL.

Jagadish

Mondrian / Impala - ORDER BY without LIMIT currently not supported
Hi!
I am trying to test BIG DATA. I have create an AWS EMR, created a couple of tables, created a connection via JDBC from PUC to Impala. Everything works fine, BUT when mondrian (jpivot, saiku) is running a query it raises the following error:
Caused by: java.sql.SQLException: NotImplementedException: ORDER BY without LIMIT currently not supported
This might be an issue from Impala, that does not allow to run a query with an ORDER BY clause without a LIMIT clause. Does anybody knows how to solve this issue ?
Is there any PARAMETER on the JDBC connection that might solve this? or is it any configuration on mondrian OR in the schema that allows me to add the LIMIT XX on the generated queries ??
Any help on this issue with help a lot!!!
Thks a lot in advance!

Is it possible to pass a parameter to a report via URL?
Hello,
I need to pass parameters via URL, in order to filter the data. For example, each user has to see their own data.
Is it possible to do that?
Thank you.

Conceptual doubt
HI all,
we have been playing with bi-server in the last couple of months to test Saiku/CDE/etc with the goal to substitute our actual data analysis systems. Probably due to our background, we cannot clearly understand how the data will be managed and performance is one serious issue we would like to address.
Unsure if I will be able to explain, let's begin with our actual structure.
PostgreSQL production database -> ETL process to load MS SQL2012 fact tables and dimension tables -> MS Analysis Server OLAP cubes -> Excel users querying data
and the test structure we have been using
PostgreSQL production database -> ETL process to load MS SQL2012 fact tables and dimension tables -> Users querying Saiku/CDE/... using a Schema (defined with Schema Workbench) on bi-server
See the gap? Even if we use MDX, the data source is a set of SQL tables, not an OLAP cube. I cannot see any way to tell bi-server to use MS OLAP cubes, neither any specification on how/where/when to store and process the fact tables to build efficient pre-aggregates and the like.
In fact, we have been using exactly the same SQL2012 tables for our testing period, but these tables are not optimized for any hugue access as nobody accesses them on our actual situation. I cannot see any reason why MDX will be more efficient than SQL when accessing the same phisical structure data.
What am I missing? :)

Incomplete MongoDB Datasource Form
I just downloaded Pentaho Business Analytics to try its reporting features on a Windows 8 machine. Currently I'm trying to use Report Designer to create a report for a MongoDB datasource, so following a book guideline I'm using this steps:
And that is the point where things differ from the book, because I get this form:
mongo_pentaho.jpg
I'm supposed to be able -according to the book- to enter host name, port and to select a collection, but the form I get doesn't allow me that. Does anyone face this issue, or know how to fix it?
- Select the Data Tab.
- Right Click on the Data Sets item.
- Select MongoDB from the menu.
- Click on the plus button to create a query

Unable to Connect to Redshift
Hello -
I have been trying to connect to my Redshift database and have received a variety of errors and the most recent one I am unable to fix. The error is as follows:
I have modified the pg_hba.conf file to include the specific host. I have also tried using a generic 0.0.0.0 address and neither have worked.
Any recommendations on how this can be remedied?

Inplicit Transaction in PDI
Hi,
We are currently evaluation the possibility of implementing and acquiring the Pentaho Data Integration solution for a large scale project, we are currently testing and analyzing this under the following environment:
• PDI 5.4 Community on Linux server.
• JVM 1.7
• MS SQL Server 2012.
• Connection drivers: JDBC jTDS and Micosoft.
The analysis by the DBA team has shown that this solution enables implicit transactions over SQL Server on each transaction (SET IMPLICIT_TRANSACTION ON). They have tried different configurations on both connection drivers in an attempt to avoid this behavior, since it brings performance issues and table locks, but had no success in it.
Is there a way to work without implicit transactions in this context?
Any information that you could provide us would be appreciated.

Using a placeholder for tablename of a database
Hey guys,
I am having an extremely strange problem with PDI once again...
I want to export some data from a database to multiple Excel files.
There is a config table within the database that allows me to map a keyword to actual table names, e.g. "rights" is mapped to several tables containing the management of user rights.
Here's the idea:
It looks like this in PDI:
pdi_forum.png
Problem is that step 2 doesn't work and causes a database error among the lines of "? is not a valid table".
So apparently PDI doesn't replace the placeholder with the actual value and I don't understand why. I did it earlier just fine (with the ? being in the WHERE clause though, but that shouldn't matter).
Does anyone have an idea as to why the placeholder is not replaced? This is driving me nuts...
Second question: Is it enough to check "Execute for each row" to create an Excel file for each value selected in Step 1? This question obviously only matters if the above can me solved. Would be nice to know anyway.
best regards,
daZza

Here's the idea:
- Select all table names where the keyword is ${param}
- SELECT * FROM ? --> Wherein ? should be the placeholder for the selected value from 1.
- Write result of the query from 2. into an Excel file

Pentaho Role Intersection
I am working with roles in mondrian schema and i would like to know if possible to make intersection of two declared roles.
I created these roles:
For product manager that has restriction on specific types of products
And financial manager that has restriction on specific country
My required result should be intersection of these two roles, i found that exist element UNION, but i found that it returns sum of both so the user can see all from both, it isn't my required solution.

Google Maps Overlay Component Pentaho v5.3
Hi !
Do you know if it's possible to customize the "pop-up" that appears on the map when we click on an area ?
Initially, there is name of the area and one value from the query.
I wanna know if it's possible to add one value to have 2 ou 3 values in the pop-up ?
And if we can add a chart as it was possible with the old system of xaction file and JSP ?
Thanks in advance.
