Oracle Rule Author(Oracle Business Rules)

Hi,
Iam implementing Oracle Business Rules, while configuring rules with Rule Author, a problem is faced, a variable data which is set in one rule's action is not available to next rule's condition.
i.e a variable set in one rule can not be used in other rule as condition.
Is there any option to make it work,
thanks & regards.

I think you would get better response on the question if you post the same question to the SOA Suite forum (SOA Suite

I took the CarRental Java model and exposed two more attributes namely numPreConvictions and ableToDrive. Then I fed it a fact where the driver has 4 convictions and ableToDrive=true. When I ran it in the rule author tester it ran out of memory indicating it may have gone into a loop. I must be missing something here. The test RL function is below the rule set code.
In my other test from outside the rule author it just won't fire the second rule (no out of memory issue). For that one I have a metalink SR 6560804.992 waiting for response. I attached some code to that one too. I got that one to work via Java Beans property change support.
1. ruleset reAssertTest
2.
3. {
4.
5. rule checkConvictions
6. {
7. priority = 0;
8. if
9. (
10. (
11. fact carrental.Driver v0_Driver && (
12. (v0_Driver.numPreConvictions > 2)))
13. )
14.
15. {
16. v0_Driver.ableToDrive = false;
17. DM.println(v0_Driver.name+" has more than 2 convictions. set able to drive=false and re-assert ");
18. assert(v0_Driver);

Syntax errors in Oracle Business Rules carrental ruleset

Hi,
I'm using Oracle Business Rules Rule Author on Windows, version 10.1.3.0.0.
I'm working with the OTN carrental sample. If i load the supplied file-based repository CarRepository from the %HOWTO_HOME%/dict directory, navigate to the RL tab -> Generate RL-code and select the 'Check RL-Syntax' button I always get the same error message:
Error:'5}' is undefined at line ... column ... in [DM or vehicleRent]
If I navigate to 'Test Rulesets' i get the same error, no matter what testfunction i use with the vehicleRent ruleset.
When i test the sample with the supplied java code i don't get any errors.
However, if I follow the steps in chapter 2 (javaFact) or 4 (XMLFact) of the Business Rules user guide and setup everything from scratch for a filebased repository i get the same error at runtime.
I based the filebased repository on the supplied emptyrepository file.
Seems to make no difference whether I use a filebased or a webdav repository.
any help on this would be appreciated.
Rob

There are two problems here. First, there is a bug that causes this error string to be displayed incorrectly when using the RuleAuthor in any browser language other than English. If you change the browser language to English, you should see:

A syntax error is found. 
Error:'carrental.Driver' is undefined at line 4 column 14 in DM

The cause of this problem is that carrental.Driver class is not in the classpath for Rule Author. This isn't covered in the how-to. See section 3.10 in the Oracle® Business Rules Users Guide (B15986-01) (available from here).

From this doc:

Create a rule set you want to test. If the data model includes any Java classes, the
Java classes must be included in the OC4J classpath. The easiest way to do this is
to put the JAR files in the following directory, then restart OC4J:
$ORACLE_HOME/j2ee/home/applications/ruleauthor/lib

or add it as a shared library using EM (specific instructions follow in the doc) and then add that shared library to RuleAuthor.

Extracting rule details from oracle business rule repository

Hi,
Which of the oracle business rule APIs provide retrieving following details :
1. Get all dictionaries stored in the oracle business rule repository.
2. in each dictionary,
2.1. How to retrieve all ruleset list in a rulesets
2.2 How to retrieve all rules in each ruleset
This is because, I want to build a custom UI to display the rule details in the oracle business rule repository. In my case, dictionary, ruleset in a dictionary and rules in a ruleset are dynamic (administrator can add, update delete at ant time via rule author UI)
Appreciate your help.
Thanks

Oracle business rule beta

hello everyone,
I am developing an application using Oracle Business Rule .
In the Rule author i want to use the variable in the form of array but
unable to declare the variable .
Any suggetion regarding this will be highle appreciable.
Thanx
saleem

Saleem,
Rule Author does not support array-typed variables. The best alternative would be to use one of the Java data structures like ArrayList.

Problem in mapping Task payload parameters to Oracle Business Rules facts

Hi all,
We are using complex types from our project XSDs inside the Human Task payload. We intend to use these Human Task payload parameters to build routing rules using the Oracle Business Rules interface. Our observation is that when the complexity of these complex types increase, the business rules editor does not show these as facts that can be used in formulating rules.
Has anybody faced such a problem before. Any help is appreciated.
We are using the following link to add routing rules –
http://docs.oracle.com/cd/E25054_01/dev.1111/e10224/bp_decision.htm
Version details :
ADF Business Components     11.1.1.60.13
Java(TM) Platform     1.6.0_29
Oracle IDE     11.1.1.5.37.60.13
SOA Composite Editor     11.1.1.5.0.01.74
Thanks,
Yamini.

Problem solved. There was an element in the xml schema that had nillable = true. Because of this the XML Fact for that element would no longer be available in the BPEL Process. Removing the nillable and generating the XML Facts again solved the missing variable problem.

Oracle Rules Manager vs Oracle Business Rules

Hi
Can someone explain the difference between Oracle Rules Manager and Oracle Business Rules.
Is Oracle Promoting both the products?
What I understand is that Oracle Rules Manager comes a part of the Oracle Database 10g R2 (and 11g) and Oracle Business Rules is a part of the SOA suite.
Is there any difference in the positioning of both these products?
Our client is evaluating various Rules engines in the market and we want to make sure that we choose the correct product.
Thanks, Srini

Igor S. wrote:
He solves the same problem with rules and without. My question was what would be better? Why would you chose one over the other. I prefer rules that is easy to state, easy to read, and easy to implement. Clear text rules in Prolog being a firm favourite. :-)
Using a rules engine, with a fairly complex API, in order to define rules? I would want very sound and very robust justification for that.
Taking this EMP table example. If there is a single AddEmp() PL/SQL procedure interface for adding employees, it is simple matter to see what it does, how it does that, and test and debug that. The only knowledge needed is the ability to read and understand the source code. The same cannot be said of rules engines.
As for the issue of updating AddEmp() with new rules. Edition redefinition takes care of versioning database objects. And in a far more controlled fashion than dealing with a rules engine that is dynamically update now! while the database is in use - and you have no real idea or real control over when exactly now! was.

There are relevant chapters in the Oracle Fusion Middleware User's Guide for Oracle Business Rules. There is sample code interspersed in the chapters.

We'll probably create one or more blog posts that dive deeper into this topic, but I cannot promise a date for that. Keep an eye on http://blogs.oracle.com/fadevrel please.

How to add Exception handling in Oracle Business rules Function

Hello,
We use to have good number of business rules in our application. So we need to have some functions in BR Composite.
Can some one let me know how to handle exception in Oracle business rules exception( Regular try catch will not compile)
is there any way please let me know.
Edited by: Network22 on Mar 25, 2013 10:21 AM

Why aren't you using por_custom_pkg.custom_validate_req_line to add extra validations.
Ensure that profile POR: Enable Requisition Line Customization is set to Yes if you were to use po_custom_pkg for Requisition line validations.
OAF calls por_custom_pkg at various points depending upon the values in Profile Options:-
POR: Enable Req Distribution Customization
POR: Enable Req Header Customization
POR: Enable Requisition Line Customization

DB Call from Oracle Business Rule +Java Method call from OBR

Hi,
1.We have a requirement in project where we need to make DB Call from Business rule.
We are using ORACLE SOA11g.
Is this possible.Any pointers on this will be helpfull.
2.Can we call java method from Oracle Business Rule.If so pls suggest how it can be done.
Thanks In Advance,
Oracle SOA User

You can implement java class to make database updates using JDBC. You can add Java class as fact in business rules and invoke methods as actions of the business rules.
Hope this will help.
