Prepare MySQL BA Repository Database

Hi everyone!


I am just starting to use Pentaho BI Server 5.0.1.
I have done the mysql configuration for Pentaho (read from this instruction http://anonymousbi.wordpress.com/201...llation-guide/ and
http://infocenter.pentaho.com/help/i...epository.html).


Login to application works fine, but when I try to create new User, I am getting the "Principal does not exists" exception. It seems, that the application does not create principal for new user.


I tried to debug the codes. The strange thing is that the it normally passes createUser function of AbstractJcrBackedUserRoleDao.java, but fails on verification in checkValidEntry method(ACLTemplate.java).


Also I can see that user is not being creatred in MySQL users table.

Problems sharing PRD reports in user console.

We are creating reports in PRD and publishing to BI server 4.8. These reports are viewable in User Console (by the user that published the report), but not "sharable". In user console, you can right-click on a report name, and you'll see the "share" function in the context menu. But when we select this function, we get an error: "could not get properties". Thus we cannot choose users to share the report with.

Any suggestions for fixing this?

Thx,

Saiku Analytics Drill Through on Cell Return Empty Result

I created my own mondrian schema using Schema Workbench and published to Pentaho CE 4.8. The schema worked well when I created new analysis using Saiku. But when I used drill through on cell, it always returned empty result without any error message. Any clue what may go wrong and how to debug it?

I tried on the SteelwheelsSales schema, the drill through function worked.

Rows duplicating on "change number of copies to start" in table output step

I have the below transformation.

sshot.jpg

There are 60 million rows to be loaded. The "change number of copies to start" property of the table output step is set to 2 in an attempt to increase throughput.
The 60 million rows need to go into both the tables, the columns differ in both of them.
The transformation was test ran with 100 rows. The tables were loaded with 100 rows each but there were duplicates in them.
How can it be ensured that only unique rows get inserted in the tables.

How to increase database throughput

January 23, 2014, 11:11 pm
$

I have a transformation which loads data in the range of 60 - 80 million rows.
When run individually it gives a throughput of more than 7000 rows/sec. The transformation has to be run for about 70 source tables each holding data in the range of 60 - 80 million rows. When run in parallel the throughput falls to less than 1000 rows/sec ( 6 transformations were run in parallel ).

Below are the settings that are currently used:

- In database connection defaultRowPrefetch = 200
- In transformation properties 'Nr of rows in rowset' is 50000
- In pan.sh JAVAMAXMEM="2048"
- In server/data-integration-server/start-pentaho.sh, CATALINA_OPTS="-Xmx2048m
- The JDBC driver used is ojdbc6.jar

There are no indexes on the target table. The database is Oracle. The server has 4 cores.
Please advise on what else can be done to increase performance.

CDA datasource with more parameters

Hello,
I created report that looks like dashboard in order to be able to send it via mail. I use graph and tables in PRD 3.9.

In first preview I get all values, then if I change value of 1 parameter (of 4), all values are gone except for table where only 1 parameter is used. Then I tried - it doesn'n matter how many subreports I have - all with only 1 parameter are working, subreport with 2 and more are without result. If I swith to the same value of parameter as in the beginning (as it worked), report is also without values except for tables wih 1 parameter.

I'm using inherited data source for reports and not adding new CDA datasource for each subreport.
My parameters have diferent default - 1 without, 1 fixed as values, 2 as date with first date of month and yesterday. -- but setting this as fixed value doesn't changed behaviour ...

What should I take care in PRD using more parameters with CDA datasource?

Thanks a lot for your help!

Time series forecasting OutOfMemoryError when used programmatically

Hi, I don't really know if I am missing something here, but when I use Weka for time series forecasting through its graphical frontend, it works nicely and fast, but when I try to do the same programmatically, I get the following error:

Code:
Transforming input data...

I am following this simple example: http://martinbmadsen.dk/weka-time-se...d-values-date/ , and yes, it works perfectly with the wine file, but it seems my file is too big, which is weird since, as I already said, it works great with the Weka frontend. My file has approximately 15000 records and only two data columns. I have also modified the memory parameters of the JVM.

I have attached my arff data file.

I have a job which have to connect to host to kill some process. When I run it on my computer with kettle, I have no problem, job running correctly. Problem comes when I want to execute this job from the Pentaho User Interface. Job is in a database repository.
So I create an .xaction, like I do for my other job. But when I want to execute it, double-clicking, I have this error in catalina.out :

Hi!
I'm using Microsoft Active Directory as security provider and I need to configure my pentaho server to authenticate the users through my DA.
I have been reading documentation for the Pentaho 5.0 CE and...From User Console Home menu, click Administration, then select Authentication from the left. The Authentication interface appears...here is the problem!! In my console, inside Administration menu i hvce only three options:
  • User and roles
  • Mail Server
  • settings

Is it possible that Authentication option is active for a Enterprise Edition exclusively??
Why i don't see this option?? :confused:
thaks thanks a lot for your time!
