Large numbers for dimensional values creates problems due to rounding up

$
0
0
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:
Code:

create table public.test (foo bigint, bar int);
insert into public.test values (9123372036854775807,1);

Next I make the following schema:
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>

Then I run the following MDX:
Code:

SELECT
[Foo].[Foo].MEMBERS ON COLUMNS
,[Measures].[Bar] ON ROWS
FROM [Test]

The measure is empy, not 1 as expected:
[Foo].[9.1233720368547758E18]
[Measures].[Bar]

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.

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:



  1. Select the Data Tab.
  2. Right Click on the Data Sets item.
  3. Select MongoDB from the menu.
  4. Click on the plus button to create a query


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?

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:

Code:

Error connecting to database [test] : org.pentaho.di.core.exception.KettleDatabaseException: Error occurred while trying to connect to the database


Error connecting to database: (using class com.amazon.redshift.jdbc4.Driver)
[Amazon](500150) Error setting/closing connection: no pg_hba.conf entry for host "xx.xxx.x.xx", user "xxxxx", database "xxxxxxx", SSL off.




org.pentaho.di.core.exception.KettleDatabaseException:
Error occurred while trying to connect to the database


Error connecting to database: (using class com.amazon.redshift.jdbc4.Driver)
[Amazon](500150) Error setting/closing connection: no pg_hba.conf entry for host "xx.xxx.x.xx", user "xxxxx", database "xxxxxx", SSL off.


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?

Thanks in advance for any assistance.

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.
Thanks in advance.

Using a placeholder for tablename of a database

$
0
0
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:


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


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

Pentaho Role Intersection

$

0
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
HTML Code:

<Role name="product_manager">
        <SchemaGrant access="none">
          <CubeGrant cube="product" access="all">
              <HierarchyGrant hierarchy="product_group" rollupPolicy="partial" access="custom">
              <MemberGrant member="[product_group].[Wardrobes]" access="all">
              </MemberGrant>
              </HierarchyGrant>
            </CubeGrant>
        </SchemaGrant>
      </Role>


And financial manager that has restriction on specific country
HTML Code:

    <Role name="financial_manager">
            <SchemaGrant access="none">
              <CubeGrant cube="country" access="all">
                  <HierarchyGrant hierarchy="country" rollupPolicy="partial" access="custom">
                  <MemberGrant member="[country].[Germany]" access="all">
                  </MemberGrant>
                  </HierarchyGrant>
                </CubeGrant>
            </SchemaGrant>
          </Role>


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.
HTML Code:

<Role name="product_and_financial_manager_for_wardrobes_and_germany_resort">
        <Union>
            <RoleUsage roleName="product_manager" />
            <RoleUsage roleName="financial_manager" />
        </Union>
      </Role>

Something like this:
HTML Code:

<Role name="product_and_financial_manager_for_wardrobes_and_germany_resort">
            <Intersection>
                <RoleUsage roleName="product_manager" />
                <RoleUsage roleName="financial_manager" />
            </Intersection>
          </Role>

This is example on data:


fact_product
id_fact_product price id_dim_product_group id_dim_country
1 100 1 1
2 150 1 2
3 120 2 2
4 230 1 2

dim_product_group
id_dim_product_group section
1 Wardrobes
2 Tables

dim_country
id_dim_country country
1 Italy
2 Germany

The result for Role product_and_financial_manager_for_wardrobes_and_germany_resort should be see data only in this range
id_fact_product price id_dim_product_group id_dim_country section country
2 150 1 2 Wardrobes Germany
4 230 1 2 Wardrobes Germany


Thanks for you help

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.
