Hi All,

I have used Pentaho EE edition form my project and I have realized that my license is expired for this version. Since I am not planning to buy EE version I am trying to use the same project files from the CE edition then I am getting lot of errors.

Example error: Unable to load job info from XML node
Index: 17, Size: 17

Is it possible to use the same Project from EE edition in CE edition as well..

Regards,
Rama

Hi Everyone,

I'm having an issue on trying to startup the bi-server.
The server always worked fine, but some days ago, when I try to start (executing the file start-pentaho.bat) the console shows only those lines on file catalina.2016-01-04.log (folder tomcat/logs):

And just stop. Anything happens then, and the server dosen't start.
Does anyone, have already face it?
The other logs files are empty.

I didn't changed any port, any file, nothing.
Any clue will help me.

Thanks, and sorry any english spelling mistake. hehe

Cannot run jobs remotely (on a server) from a client machine using Carte

Hello,
I have been trying to setup PD! 6.X CE as client server environment using carte (so that users can run their jobs on a central server). I used the following post as a reference: http://wiki.pentaho.com/display/EAI/...le+environment. So far I have been able to 1) Successfully run Carte on my server and check its status.
2) Setup a repository in MySQL and connect to it (both from server and client machine)
3) Create a test job and setup the slave server settings
When I launch the job (with the remote execution option) from a client machine the connection times out and I get the below error:

Hi,

I have two identical strems and I would like to get the difference between these two streams. Below is the statement that I use in the database, however I would like to do this before inserting the data into the database.

Hi all,

PDI Noob here with a question...

Short Version: If a user runs a transformation on a Windows server, can it be made to run under that user's Active Directory account? (Please say "yes"). If not, how can a transformation tell who launched it?

Long Version: Real Soon Now we will have a shiny new PDI server on Windows integrated with Active Directory.
But I am not yet sure what "integrated" will turn out to mean. I am hoping it will mean:

• Nobody has to explicitly provide any credentials when running a transformation on the server (or have them baked into a .ktr file / set in an environment variable etc);
• The transformations will run under my account not some system account;
• If my transformation connects to SQL Server using Integrated Security, my credentials will be used;

Is that how things work?
If it isn't, is there at least a way a transformation can tell who launched it so this information can be passed to a service?

Ed

I have a mondrian schema, with standard measures.
I'm new to MDX so I guess this makes my task a bit more difficult, im struggling with the syntax of the mdx formula.

Is there any way to test my mdx formula to see the results it returns?

Does anyone have any links to some information / tutorials / guides on implementing a calculated member in Schema Workbench to help me?

Thanks

hi to all,
i'm early new with Pentaho.
That's my use case.
I use SSO Jboss Keycloak as my single sign on server. I have already developed few applications which already use it, now this is the time to wrap Pentaho BI inside the SSO mechanism.

I have read Pentaho authentication is based on Spring Security and luckily Keycloak offers a Spring Security Adapter by which i can secure a spring secured application with keycloak authentication.
Can someone help me by listing some steps i have to do in order to develop an authentication keycloak provider to be integrated inside pentaho authentication process?
I mean that:
- when i try to login pentaho web application i will be redirected to keycloak SSO login form.
- when i try to access pentaho web applications, being already authenticated by other applications, i can do it without any credential request.

Coming more into detail, i have successfully tried to develop a spring secured application using keycloak SSO.
It could simply done by modifying the security-context.xml as the following listing:

<beans xmlns="http://www.springframework.org/schema/beans"

So i m wondering if this mechanism could be easily imported into petaho application-security-context.xml

Thanks a lot

Happy new year for everybody.

Can someone post the complete steps to configure eclipse to build pentaho 6? I've been trying for a week but something keeps not working.

I used tutorial for 5 as base.

Thanks in advance.

Carte execution ID vs JOB execution log

Hi,
I've developed a job flow with lots of transformations and I also enabled job and transformation logging.
I've enabled carte and I can execute the job by invoking a URL.
The return after URL call is:
<webresult>
<result>OK</result>
<message>Job started</message>
<id>549387d0-e621-4b6f-aa63-2783a2116e7c</id>

</webresult>

What I want to do is to check at log tables from jobs and transformations wich carte execution ID (in this case "549387d0-e621-4b6f-aa63-2783a2116e7c") generated the log lines.
I can see lots of possible columns like CHANNEL_ID, PARENT_CHANNEL_ID and ROOT_CHANNEL_ID but none seems to save the CARTE execution id.

Does anyone know how we can check wich carte execution ID generated the job/transformation log lines.

Many thanks in advance,
Ronaldo Akamine

Hi Everyone,

I amtrying do incremental load. And it's type 1 dimension. The old data getsreplaced new changes.

I amgetting the max(last_modified_ts) from the target table using "Table Input1" and pass it thro' another "Table Input 2" in where clause to
get onlythe changed records from the source. And up to this part, it works.

Afterthat, I need to compare the column "col_pk" from "Table Input2" result set against "col_pk" of "Target table".
If
TableInput 2.col_pk = target table.col_pk then compare the remaining columns in thetable to check if there was any change. If so, update that record.
If
TableInput 2.col_pk = target table.col_pk and when compared there is no changes toremaining columns then don't update.
If
TableInput 2.col_pk not found in target table.col_pk then insert into target table.

It's kindof merge. So, I tried merge rows - diff. The flagfield for insert and updatecomes as "new" and the not changed records comes as"deleted".
Or I can"delete" the new records from target and then "insert". Inboth cases, I am not sure, how to pass this "flagfield" to triggerthe delete and insert or
updateand insert. Please find attached document that shows merge rows-diff setup andthe results set.

Pleasehelp.

Thanks,
Raji.

Searching for ideas, resources, documentation, demos etc...

Requirement is to leverage PDI (Enterprise Edition) capability to execute the following work steps.

1) Extract/Filter a data set (thousands of rows, csv file)
2) Pass the ENTIRE data set to a ML algorithm (writing in Python) which will add additional columns to every row.
3) Capture the ENTIRE data set from step #2 and insert to a RDBMS.

Looking for options/insight on how to implement Step #2.

I understand there is a R Language plug in. Is there one for Python ML?

How do I print CTools dashboards in Pentaho?

This is a question that often keeps coming back. Even for my own reference I decided to just compile the answer that I always give in a blog post links to the relevant resources

This is a simple question with a not so simple answer. Screen and paper obey such different rules that really depends on what the customer is looking for. There are 3 common approaches:

1. The browser button

Just use the browser print button (or a button in the dashboard that uses window.print() as the code). This has the obvious advantages (dead easy) and the obvious advantages as well (the actual output depends on the browser)
2. PhantomJS on server side

Use phantomjs on the server side. Not drastically different than the previous but possible to control the output. I know of a customer that even implemented scheduling of PDFs this way. Harder to setup. Some links:

• http://joshid.github.io/blog/2014/10...ho-pdf-export/
• http://www.osbi.fr/exporter-en-pdf-d...vec-phantomjs/

My favorite approach - PRD

The truth is that screen and paper is not the same. There's no 1:1 mapping, even with CSS media queries the result will be, at best... meh.


My personal favorite is actually leveraging the most appropriate tool on our stack to print: PRD. My recommendation is that we build a report using the resources of the dashboard (queries and charts) and build the pixel perfect representation of the dashboard as a report. References:
