Created XMI but cannot see datasource in Ad Hoc Report Designer

August 23, 2013, 1:20 pm

So I have created an XMI file and placed it into a solutions folder, but when I go to create a new Ad Hoc report on my BI server nothing shows up. I assume there is more to publishing an XMI file than just placing it in a solutions folder. Does anyone know how to do this through the Webservices or Pentaho Java API? I do not want to use PME for this. If anyone has any information it would be a great help.

X-axis using logorithm scale

≫ Next: Is there a way to filter the data in the postFetch process?

≪ Previous: Created XMI but cannot see datasource in Ad Hoc Report Designer

Hi All,

I am wondering if there is a way to change the scale of the x-axis to be logarithm instead of linear, it appear to be doable in protovis
var yScale = pv.Scale.log(0,popCountArray.length).range(0,height);
I have a dot chart that would like the x-axis ticks to be 0, 100, 10000, 1000000, 10000000,
instead of 0, 2000000,4000000,6000000,8000000, 10000000

If it is doable, where and how can I do it?

Thanks.

Is there a way to filter the data in the postFetch process?

August 23, 2013, 5:17 pm

≫ Next: schema workbench, problem to assign roles to virtual cube

≪ Previous: X-axis using logorithm scale

Here is the story:

I have a metric dot chart that display asset risk data for a given year, the x-axis is the consequence in $, and the y-axis is the probability of failure for given asset risk.

In the Dashboard, I created a drop-down list for year selections. So every time a year is changed, the data source will listen to the year parameter change and fetch some data using SQL over Jndi, and then the chart will be refreshed.

Everything works pretty well except we would like to improve the performance of this chart by preventing it going through data source every time the year parameter is changed. Instead, we are hoping to achieve the following:

When chart is loaded, we preload Asset Risk Data for ALL years. now, with parameter change, instead of refetching the data from data source, is it possible to do the data filtering in the post fetch event by calling setData?

Say if I have the super data set as
Year RiskName Consequence Probability Of Failure
2011 Risk1 $50 .5
2011 Risk2 $10 .3
2011 Risk3 $54 .2
2012 Risk1 $150 .4
2012 Risk2 $13 .7
2012 Risk3 $56 .8
2012 Risk4 $156 .6
When Dashboard is loaded, we filtered the data based on year selected, and display the chart accordingly. If we first selected year 2011, then only risks for 2011 will be displayed, i.e., there will be 3 dots on the charts representing risk data.
Then when we change the year to 2012, with some sort of filtering logic + dropdown event listener defined, the chart will immediately display 4 risk data for 2012 without refreshing the chart, since all the data has already been loaded.

Question is:
1. Where do we save this preloaded super dataset?
2. How do we allow chart to filter the preloaded data based on parameter?
3. Can we prevent the chart from loading everytime the parameter is changed?

Is it doable? Is there anything that is missing? Am I over simplify the logic here?

Thank you for the help!

Regards

So far I have found this one http://www.prashantraju.com/projects/pentaho/ which is a really great starter but seems to differ in some aspects to 4.8

calculate value from old and new record during update

August 26, 2013, 12:47 am

≫ Next: Send output data in batches to REST api

≪ Previous: Can I send parameters to Interactive Report ?

Hi all,

I have following kind of target dataset, ID1 and ID2 are the keys.

ID1 , ID2 , Value
100 , 10 , 90
100 , 20 , 95
100 , 30 , 92

I need to update this dataset using a import dataset. e.g.
ID1 , ID2 , Value
300 , 30 , 90
100 , 20 , -15

The first record of the import dataset needs to be inserted, no problems there. Using Table output will do the trick.
But the second record is special, instead of a normal Update, I want the following to happen:
In the target dataset, find the record matching the keys: 100 , 20 , 95
Now I want to add the imported value to the target dataset: 95 + -15 and update the dataset.

The resulting record would be: 100 , 20 , 80

The end result:
ID1 , ID2 , Value
100 , 10 , 90
100 , 20 , 80
100 , 30 , 92
300 , 30 , 90

I don't see how to achieve this with Update or Insert/Update, this will result in 100 , 20 , -15
Any thoughts about this?

Thanks in advance,
Herbert.

Send output data in batches to REST api

August 26, 2013, 1:25 am

≫ Next: Hadoop Online Training

≪ Previous: calculate value from old and new record during update

Hi,

I want to send data over REST api in batches. e.g. 100k records are getting imported from particular table and some transformation is done on it. Now I want to post that data to REST api, each call with batch of 1k records. Is there any support to do batching of output rows? After record count is matched with batch size, REST call will be made. And record count will reset to 0 and process will continue.

100k [??] 1k x 100
DB ------> Transformation ----> Data splitter ----------> REST api

Another possible way to achieve the same is open input connection to DB and read 1k records, transform and post to service. Repeat the same procedure till all data is read. It will use loop in job, but loops are useful for small number (as per some post on forum). We may have 1 million records, looping over such data can create memory overflow error. so is there any other way to implement this approach.

Thanks.
