Data Visualization Desktop 4 what is new - part 1

Two weeks ago, Oracle released a new version of Data Visualization Desktop (DVD / DV Desktop), with lots of new options. Making it very interesting for the data analyst - data scientist spectrum.  I'll talk about it in Part 2. Lets cover some basic changes first.


My first reaction was, wow, it looks so different.

See a video by Oracle Analytics about major changes here.

A list of some of the changes:

  • It's clear we have a new home page and UI. We can customize by clicking top right corner:



  • New file based data sets can be added simply by drag and drop (beyond the regular ways):

  • New "Create" menu:






Some major changes happened in Projects.


  • The UI

  •   In previous versions there was clear difference between Visualize and Narrate. Only in Narrate we could have separate filters for each Canvas. Not anymore. Now we have the "Pin to All Canvases" filter option.


  • For each object there is a relevant properties Panel in the left corner:

(Did you notice the data type option "Number" and not "Integer" or "Double"? For updates, the original data types remain, until you change to "Number". It's not a bug).

  • We can copy/paste visualization between Canvases as well.
  • Data Action (Navigate to BI Content and Navigate to Web page, are the names in Answers). With Type options "Canvas" and "URL" and ability to open other Canvases. I hope to write a specific post about this option. Meanwhile, see a video by Oracle Analytics here.






















  • In the same Project we can have various unrelated data sources.
 
  • The Narrate option can be built by selecting Canvases. We can add notes wherever we want. It has less functionality now, and oriented for presenting a story based on Visualize components + Notes. (As a result, you might see few extra canvases in "Visualize" in upgraded projects from version 3.)

 Consider spending some time on the Narrate Properties Pane. They are several very interesting options there.

  • Date/Time columns have automatic creation of hierarchical levels. 

  • Date/Time level can be set and switched from Properties Panel at each visualization.

  •  We can show metrics as Percentage (similar to Answers Pivot)



  • Automatic Binning of metrics/measures when used as Categories (and, of course, control of the binning): 





  • The list of data sources is growing:
  1. Data Files (Excel, CSV...)
  2. Oracle Applications (Including OBIEE)
  3. Oracle Big Data Cloud (Beta)
  4. Oracle Data Warehouse Cloud (Beta)
  5. Oracle Database
  6. Oracle Content and Experience Cloud
  7. Oracle Essbase
  8. Oracle Service Cloud
  9. Oracle Talent Acquisition Cloud (Beta)
  10. Actian Ingres
  11. Actian Matrix
  12. Actian Vector
  13. Amazon Aurora
  14. Amazon EMR
  15. Amazon Redshift
  16. Apache Drill
  17. Apache Hive
  18. Cassandra
  19. DB2
  20. Dropbox
  21. Google Analytics
  22. Google Cloud
  23. Google Drive
  24. Greenplum
  25. Hortonworks Hive
  26. HP Vertica
  27.  IBM BigInsights Hive
  28. Impala
  29. Informix
  30. Map R Hive
  31. Microsoft Access
  32. MonetDB
  33. MongoDB
  34. MySQL
  35. Netezza
  36. Pivotal HD Hive
  37. PostgreSQL
  38. Presto
  39. Salesforce
  40. Spark
  41. SQL Server
  42. Sybase ASE
  43. Sybase IQ
  44. Teradata
  45. Teradata Aster
  46. Elasticsearch
  47. JDBC
  48. OData
  49. ODBC

Of course, if you have the last 3, the sky is the limit.😉




In the next post I will talk about the really interesting stuff of Explain column and Machine learning.

Problem loading java datasource OBIEE 12.2.1.3

You are trying to load Java Datasources... with OBIEE 12.2.1.3 And get Error 404 page not found.



You see the same problem with http://YOURSERVER:9502/obiee/javads?status.

I had this problem on Windows server. probably exists on other platforms as well.

Solution:

Logon to the weblogic console (in my case http://MYSERVER:9500/console)
Select Deployments

Find there obi.datasrc.server


Find the Target tab,
Press Lock & Edit
enable bi_cluster (leave the bi_internal_virtualhost1 for next step)



Save and
Activate Changes:

Press Lock & Edit again
disable the bi_internal_virtualhost1
Save and
Activate Changes again.

(I got an error trying to do both in one step).



Now it should work:

OBIEE 12.2.1.3 is available

The latest release of the on-premises version of OBIEE, 12.2.1.3 is available for download here.
There seems to be a little problem with the JDK link, here is the link to download page.  
The documentation page is here.


From the above mentioned documentation this seems to be the new features of the release:

The short version


  • SSO between OBIEE (clasic home page) and VA / DV (new home page).
  • Publisher new features.


The longer version



New Security Features in Oracle BI EE 12c (12.2.1.3.0) include:

This release uses OpenSSL version 1.0.2h.
Lightweight Single Sign-On (SSO)
Lightweight Single Sign-On (SSO)
Users can log in to Oracle Business Intelligence once and navigate between the Classic (Analytics) Home page, Visual Analyzer, and the new Home page.
Lightweight SSO is enabled by default in Oracle Business Intelligence for new installations only. If you patched Oracle BI EE to the latest release, lightweight SSO is not enabled by default.
If external SSO is configured, lightweight SSO defers to the external SSO configuration. Oracle BI EE uses the same mechanism to enable internal lightweight SSO and external SSO.
If you need to disable lightweight SSO, use the WSLT disable SSO command.



New Features and Changes for Oracle BI Publisher 12c (12.2.1.3.0)
Job Priority and Recovery
You can set the priority of each report to avoid delays of critical jobs and recover interrupted jobs to increase the success rate of running jobs.
Restricting Embedding of BI Publisher in iframes
You can prevent embedding of BI Publisher in iframes.

Defining Job Priority
You can assign critical, normal, or low priority for a report in the Report Properties page. BI Publisher processes the reports based on the report priority. 
In Release 12c (12.2.1.3.0), you can view the priority of a job and identify the critical jobs in the Report Job History page.
Using New Functions and Commands in eText Templates
You can use the following new functions, commands, operator in an eText template:
XPATH function to generate the XSL template.
Variable handling functions. See the descriptions of AddToVar, AddToVar, ResetVar, and SetVar functions in Functions.
