Oracle B2B, Viewing EDI files

For sophisticated developers (like me) EDI files can be viewed in editors, the one which I use is

Liason EDI Notepad

https://www.liaison.com/products/integrate/edi-notepad/compare-versions/

version: Express (Free)

The file which I have shown in my last post just save it with some name and extension as .edi
example: sampleEDI_850.edi and open it in EDI editor. I should look as below.

Anyways viewing the EDI file is the last part. 

Oracle B2B, Introduction

Oracle B2B is a technology which converts XML data to EDI, ebXML, RosettaNet etc formats and vise versa .

EDI, RosettaNet etc are electronic versions of documents in a standardized format which are machine readable, have a look at EDI 850 document below.

This document is similar to XML, or it will be correct to say XML is a better human readable form of EDI, these formats came into existence in early 1960's, each character,*, space has a code behind it, which was agreed upon when these standards were made. 

Just to explain how impressive these codes are, if the similar data is send in XML it will be 100 times bigger.

In crude SOA terms B2B is similar to file adapter which converts XML to flat file, and in this case the flat file is a EDI file, and it also polls for the EDI file and converts it back to XML and can place it in JMS Q or AQ from where SOA can pick it up for further processing.

Dynamically changing XSLT file name in BPEL

I recently came across a scenario where multiple BPEL process were doing the same work, the only difference was the transform activity. So for re-usability we  create a single Composite which dynamically pick the XSLT file on the basis of requirement from MDS.

So the benefit will be every time there is a need to create a new composite we just have to create a new XSLT file and place it inside MDS and the BPEL process will pick it up.

To achieve this transform activity allow us to pick the file from MDS however we can't change the name of the file dynamically.

However assign activity allows us to execute the XSLT file we have  a function

ora:executeXSLT(location of XSLT file, input xml)

Below source code from Assign will make more sense


 
    dvm:lookupValue("XSLTFileLocations_MDS.dvm","TARGET_SYS",$FileName,"MDS_XSLT_LOC","N/A")
    $XSLTFileName/ns3:XSLTFileLoc
 

 
    ora:processXSLT($XSLTFileName/ns3:XSLTFileLoc,$ReceivePO_Consume_Message_InputVariable.body)
    $InvokePO_send_InputVariable.body
 

 
Below is how the dvm looks like

Business Rules, IF THAN, Otherwise

Recently I came across a scenario where the existing business rules implementation fails because the condition which it was checking did not exist.

Rule 1
IF (Name="YATAN")
THAN
FULL_NAME="YATANVEER SINGH"

Rule 2
IF (Name="YAGYA")
THAN
FULL_NAME="YAGYA VIR SINGH"

The above rule works fine to the point it checks for particular inputs YATAN or YAGYA, however as soon as it checks for something else it throws error.

Fact not found in the rule engine working memory, rule session execution failed.

The rule session 26557551 failed because an instance of the fact com.oracle.xmlns.frd_wms.testbr.bpel.ProcessResponse could not be found in the working memory of the rule session.

This is most likely a rule modeling error. The decision service interaction expects the fact instance to exist in the working memory of the rule session. Check the rule actions in rule designer and make sure that a fact of the expected type is being asserted. If the error persists, contact Oracle Support Services.

So we can handle this by putting a otherwise condition, however
After some research, I found that there is  no otherwise :)

So came with a solution (not the smartest)

I put a new rule

Rule 3
IF (Name != "YATAN")  and (Name != "YAGYA")
THAN
FULL_NAME="YUGANSH VIR SINGH"

Getting Started with Oracle Event Processing 11g, Packt Publishing : Review

I am working on Oracle Event processing, so thought of getting a book which can help me,
over the internet I found the book "Packt Publishing: Getting Started with Oracle Event Processing 11g".

This is a completely useless book, the author has no idea what he is writing, he has not explained a single sample, he has simply told like we need to put entry in this and that file, the steps are not clear, actually there are no steps. The attached project examples are not getting compiled. The sample code (Java) given the pdf book is in the form of pictures, so we cant copy paste it.

I am very upset with Packt Publishing who has allowed such a useless book to be publish under its banner with name as "Getting Started".

Oracle Complex Event Processing, Installation

I have installed the Oracle Event Processing 11.1.1.7 on my Windows 7 32 bit machine.

To get the software we can follow the below steps.

  1. Go to https://edelivery.oracle.com and sign-in/register.
  2. On the Media Pack Search, search for Oracle Fusion Middleware and your platform (Win 32 bit)
  3. Scroll down and click on the link for Oracle Fusion Middleware 11g Media Pack.
  4. Select Download for Oracle Event Processing 11g (11.1.1.7.0) for Win 32

Follow the below steps:

1. Unzip the file and right click and run as admin.

2.

3. 

4. Choose custom so you get the samples.

5.

6. 

7. 

8. 

9.

10.

11. 

We are done with the OEP software and server installation, next lets create a domain.

 12.

13. 

14.

15.

16.

17.

18.

19.

20.

Domain creation complete, now lets make our Eclipse IDE ready for development, for this we will
have to use the plugins.

21.

22.

23.

24.

25.

26.

27.

28.

We need to restart the Eclipse to take effect, next we need to integrate the OEP server integrate with
Eclipse so that we can start/ stop/ restart and deploy directly.

29.

30.

31.

32.

33.

34.

35. Now click on the green button to start the server.

36. Open the URL to see the server page.

The page will not login, go to eclipse > servers, double click to open the server overview

37. Change the passwords here to weblogic/Welcome1, restart the server again and then login.
