Hi All,

I am new to Pentaho BI, i have tried to integrate my Java web application with tomcat (which comes along with BI server) , but when i deploy it and restart tomcat, its not getting started, my main aim is to use only tomcat within single system, so
Can i integrate Pentaho bi server with already existing tomcat, which i already had it prior to installing Pentaho BI ?

Looking through the bugs database this type of issue gets closed because it cannot be duplicated.

CDE Chart doesn't display date correctly

Hi guys!

I have a problem in making a chart: I'm training on make charts using CDE.
My problem is, like you can see in the attachment, that the x-axis, that represents the time, is categorized and doesn't scale on the total time.

CCC-problem.jpg

Practically, here in the image, you see that 00.05 is equidistant from 00.00 to 01.00 when I want that this is re-scaled.
I found some clue in http://www.webdetails.pt/ctools/ccc....me-series-line but I didn't find the field "dimensions" in the CDE and I didn't found how I can inject category: {valueType: Date, isDiscrete: true } inside the CCC Line Chart component.

How did you resolved this? Thank you in advance

hi,
I'm trying to create a zip file with two input files.

The first 'zip file' step works fine, but the second 'zip file' step even with the option
'if zip File exists' set to 'Append file to the existing'
fails with a 'Could not create file XXXXXX , exception:URI is not absolute'.

Tested all I am able to imagine but no way: if the zip file exists I canot append.

What am I doing wrong?

Null values when Joining MSSQL -> MySQL

February 24, 2014, 3:58 pm

Hello all,

I've been trying to create a pretty straight forward job that takes a few thousand records from a MSSQL database, and pulls certain foreign keys from a MySQL table. Once I have these reference keys, I'd look to make an insert in the MySQL database for the records. (For those curious, I'm taking my Dynamics GP invoice line items and putting them in MySQL to run batch e-invoicing...)

My issue is that no matter what tool I use, I get null values from the MySQL records. I've sorted everything on the given key in Ascending order, used Merge Join, Stream Lookup, Database Lookup, and probably one or two other options that I can't recall.

Does anyone know why I might be having issues? Both fields are formatted as strings (the key generally fits the format `CSL-####` or `SSL-####`), so I don't think its a data type issue. After about 15 hours into tinkering, I think I'm up against a wall here.

Any help is appreciated!

Edit - solved, see below, was a silly issue!

Multiple Classifications Problem

Hello everyone,

I just started using weka. I have read and watched multiple tutorials that explain how to use weka for classification. But now I am not sure if weka is the right tool for my problem.

The dataset that I have contains 10 networks. Each network is being descried by a number of attributes. Then I have to classify my 10 networks to three classes A, B, and C according to four different tests.

For example, according to their sizes, my networks will be classified into A, B ,C. Then
according to another criteria, my networks will be classified again to A, B, C. And so on for four times

Obviously, each network will appear in a different class each time. And here where I needed to use weka.

Does weka classification support this? Because all what I have seen so far is to use one classification attribute.

Any help will be greatly appreciated.


Thank you.

Which is better option for ordering on attribute column .Value or .Name?

February 25, 2014, 12:44 am

Using Foodmart sample cube we are trying to Sort data based on Attribute column.


Following is Sample MDX where we are applying sorting, (here we are using CurrentMember.Value while sorting data):


SELECT {[Measures].[Store Sales]} ON 0, NON EMPTY ORDER({[Customers].[Customers].[State Province].AllMembers}, [Customers].[Customers].CurrentMember.Value, BDESC) ON 1
FROM [Warehouse and Sales]


in above MDX as we are trying to perform descending sort based on Attribute column, it should sort it on that column, but instead of doing that it incorrectly sorts the value based on measure column available in MDX.


Now if we use CurrentMember.Name it correctly sorts data based on Attribute column. Following is sample MDX query for same:


SELECT {[Measures].[Store Sales]} ON 0, NON EMPTY ORDER({[Customers].[Customers].[State Province].AllMembers}, [Customers].[Customers].CurrentMember.Name, BDESC) ON 1
FROM [Warehouse and Sales]

Please find attached screenshots for same queries and results for both executed over Saiku Analytics plugin on Pentaho Server.


Our observation is CurrentMember.Name gives correct ordering where as CurrentMember.Value does not give correct ordering. What according to you is the better option?


Thanks,
Hardik

I need to hide a line on my subreport when the data is null there. The labels you can hide using if-null attribute and in expression write if statement formula, but the line hasn't that attribute.
