Multiple column join

Hi,

I have 2 tables with the following join:

customer.cucomp = sales.stcomp and
customer.cuacno = sales.stacno and
customer.cudels = sales.stdels;

When I select the first join above I can create the join in Business Analytics but when I select the others I get the message that the join already exists.
Is it possible to do a multiple column join in Pentaho Business Analytics 5.0 using the data source wizard?

Thanks.

Hi Guys,

The values are only shown in "Internet Explorer 8" BUT Mozilla-FireFox, Chrome, and IE(upper than 8) don't show the values of Bar Charts. they are only shown (in all navigators) in the localhost access but distant machines don't show these values.

Help please.

Kudos - DataCleaner and PDI-CMIS-PLUGIN (alfresco migration)

Converting a legacy MS Access storage with file system locators to PDFs and TIFFs to Alfresco (not exactly traditional ETL...).

Fabulous success using the DataCleaner plugin to review outliers of the current content datapoints (attributes of documents that have been mistyped, format of attribute contents that are outliers, controlled list reviews, and other data to be cleaned up prior to populating the new storage location).

And great success using the PDI-CMIS-PLUGIN for injection into Alfresco (https://code.google.com/p/pdi-cmis-plugin/). Not as fast as a Bulk Filesystem Injection approach, but a standard and repeatable approach that was really easy to setup and support.

So...Kudos!

Tips for optimizing transformation throughput in embedded Kettle

May 27, 2014, 8:48 am
$

Does anyone have any tips or links on methods by which I can optimize the throughput of repeatedly running a transformation over small input sets (through an embedded instance)?

Using the example embedded Java documentation I've been able to setup a simple transformation and inject the input record / collect the results but performance on calling this 'loop' isn't what I'd hoped. I'm currently seeing 11-12 seconds on calling the transformation 50 times with 2 input records per iteration. Calling the same transformation once with 100 input records yields a processing time of 2.5-3.5 seconds.

I've tried setting the TransMeta.setTransformationType to SerialSingleThreaded and this boosted the performance from ~12.5 secs down to ~11.5 secs but was wondering if there was yet more ways i can optimize the internals to get closer the single transformation throughput.

I'm guessing it's something to do with a combination of thread polling and the setup / startup overhead of a transformation but would appreciate any tips that others may have on this subject.

Thanks

Please help-- Need to pass database connection details as parameter/variable

Hi All,

I need to pass database connection details (such as host name, user id , pwd etc ) as parameter or variable so that I can change the database for each execution.

I have created a transformation where I am passing these details to set variable step and using these variable in the database connection.

Line chart margin control options?

May 27, 2014, 9:47 am
$

In the advanced properties of the CCC Line Chart, there's the "margins" parameter for the root chart. Is there any way to specify the top/bottom/left/right margins in this parameter? I've tried passing various arrays like [50,0,10,0] but to no avail. Of course I could control the object's css/div margins outside the chart, but the reason I'm trying to manipulate the internal margin is so that I can add a few labels off to the left of my chart.

I added a panel in plotBg_add, then added the labels with a negative offset so they would show to the left of the chart, to the left of the y-axis tick labels. This works ok, but I end up with a huge margin on all sides, when I only need that increased margin on the left. If I don't have a large left margin, the labels are cut off.

For example:
.add(pv.Label)
.text("Mean")
.bottom(function() {return this.parent.meanDef(); })
.left(-50)
.textStyle("green");
Maybe there's a smarter way to accomplish this? Thanks in advance!

Cannot browse files from User Console using Crystal theme. OK using Onyx.

When the Crystal theme is selected for thr Pentaho User Console everything seems to work apart from the Browse Files feature.

On clicking the 'Browse Files' button the files page is presented with no directories, files or hierarchy and just a pinwheel timer turning at the top.

The pinwheel turns and nothing happens. Refreshing the page makes no difference. All other actions on the page are disabled.

There is no timeout - or at least no timeout shorter than the 20 mins I just waited.


This only happens using Crystal. Using Onyx as the theme all is OK, I can browse and select files with no trouble.

The answer would be "Well use Onyx then" except that I find the dark look very uncomfortable to use.

Any ideas?

Thanks in anticipation

Setting up WebEx on Ubuntu 14.04 (64 bits)

May 27, 2014, 4:30 pm

This blog entry may seem a bit offtopic. But Pentaho uses webex quite a often, and I'm a linux user. I had multiple problems using it properly, so I figured I should write a blog post on how I set it up for future reference (yeah - I mostly write blog posts so then I can later come back and see it... a public note pad)

Basically, there's a couple of issues with webex on linux 64 bits. Some reported solution involves installing a 32 bits version of firefox and java - which is at best... hum... well, silly!

I took some time to debug it, and found some very interesting info on the internet, that I took as main reference. The rest was mainly trial and error. I used firefox (the latest version, currently 29) and the latest java7 package / mozilla-java-plugin (java-1.7.0-openjdk-amd64)

The problem

From what I could gather, the problem is that webex for linux is dynamically compiled against a 32 bits system. Webex downloads it's dependencies to a folder on the home directory, in ~/.webex/. We can check with:
pedro@arpeggio:~/.webex/1324 $ file libatdv.so
libatdv.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, stripped
Next step is to find which libs aren't linked, for which I use ldd
pedro@arpeggio:~/.webex/1324 $ ldd *so | grep not
libpangoxft-1.0.so.0 => not found
libpangoxft-1.0.so.0 => not found
libjawt.so => not found
libjawt.so => not found
libpangoxft-1.0.so.0 => not found
libXft.so.2 => not found
apt-file is a good utility to find out where to get those packages:

pedro@arpeggio:~/.webex/1324 $ sudo apt-file find libpangoxft-1.0.so.0
libpango1.0-0-dbg: /usr/lib/debug/usr/lib/x86_64-linux-gnu/libpangoxft-1.0.so.0.3600.3
libpangoxft-1.0-0: /usr/lib/x86_64-linux-gnu/libpangoxft-1.0.so.0
libpangoxft-1.0-0: /usr/lib/x86_64-linux-gnu/libpangoxft-1.0.so.0.3600.3
After that, we need to find the best candidate for this package, and install it. The important bit is that we need the 32 bits version. We need to follow this procedure for all missing deps. In the end, these are the packages that I end up installing (Note: I wasn't able to fix the missing dependency on libjawt.so, but even without it everything seems to work)
sudo apt-get install libxmu6:i386
sudo apt-get install libpangox-1.0-0:i386
sudo apt-get install libpangoxft-1.0-0:i386
And that's it!
Other distributions

This is for ubuntu, specifically for 14.04. For other distributions the method of using ldd to identify the missing deps is the same. Finding which package provides it... it's another story.

Bootstrap nav bars + chosen JQuery selects + responsive jQuery selects

Hi Forum,

I am trying to demonstrate a high level interactive dashboard using bootstrap css as shown in below image.
I've found below things..

As I noticed that currently there is no integration of selects of bootstrap available I'm trying to take chosen JQuery selects & bootstrap panels/nav bars and when I take bootstrap nav bar code(below code) and chosen select .. the select component is giving error(shown in image)...

If I remove the nav bar code(below code) then the chosen jQuery select component is appearing on the dashboard.. tested many a times.

1) Is chosen JQuery selects not compatible other bootstrap code ?
2) Or how to take bootstrap dynamic drop downs/calendar picker and other components and map them to chats ? (Will it be a future CDE release or any work around needed now to make as the default components works ?
3) How to make responsive chosen drop downs ( tried to change the width of a select component ?
Tried to give
$("select").chosen({ width: '100%' }); // width in px, %, em, etc (from this site : http://dirtandrust.com/blog/chosen-j...sive-goodness/

All the code written places(java script, PostExe,PreExe and etc of chosen dropdown) but unable to get it solved ..


Your inputs and findings will be helpful for a rich mobile compatible dashboard development.

Thank you...
