ODI 12C and OBIEE 12C Integration with SOAP WSDL

I have attached a link to the step by step instructions at the end of this post on how to integrate SOAP WSDL from ODI to OBIEE so you can start ibots or do various other tasks within OBIEE from ODI without the need of a dedicated ODI agent on the OBIEE Server. This solution was developed in 12c.




Business Case


One of our customers wanted OBIEE reports to be mailed after the completion of a data load in ODI. We know there are different methods of achieving this. But we did not want to deploy an ODI Agent onto the OBIEE Server in the Corporate Environment.
That is the need and here is the solution we came up with – Using WSDL & SOAP approach to build bridge between the two most popular Oracle technologies in Data Warehousing world.

Solution Technology


We used the two following technologies that are made available as part of ODI and OBIEE while building the solution
WSDL (Web Service Definition Language) is often used in combination with SOAP and an XML Schema to provide Web services over the Internet. A client program connecting to a Web service can read the WSDL file to determine what operations are available on the server. Any special datatypes used are embedded in the WSDL file in the form of XML Schema. 
SOAP (Simple Object Access Protocol) is a protocol specification for exchanging structured information in the implementation of web services in computer networks. It uses XML Information Set for its message format, and relies on application layer protocols, most often Hypertext Transfer Protocol (HTTP) or Simple Mail Transfer Protocol (SMTP), for message negotiation and transmission

Solution Overview

The solution enables us from ODI to remotely login to OBIEE and initiate an iBot and log out. Following are the high level steps

   1.     Use OdiInvokeWebService to login to OBIEE with SOAPImplementation URL  
   2.     The above call creates a response file with the OBIEE Session Id
   3.     Use a Simple mapping to move this file content into a database table
   4.     Create a variable with sub string and in string operations to extract the OBIEE session id
   5.     Use OdiInvokeWebService to initiate an iBot with the above session id and iBot name to        mail the required report to recipients
   6.     Use OdiInvokeWebService with the same session id to log off from OBIEE

We have created an ODI package to orchestrate the above steps which executes the above steps in a seamless chain.

I think Power BI and its combination with Oracle and some other database operating platform can surely help in cracking some complex IT solutions.
