Not able to access the web based RuleAuthor of Oracle Business Rules

Hi ,
I have Installed Oracle SOA Suite (11g) version from here .
I have followed the steps in the Installation guide .
I was able to install it successfully. At present I need to Work on the oracle Business Rules.
As per the documentation I have tried to access the Rules author at the following URL

But I was not able to access it.
Please let me know if I need to install any other component to access Rule Author. please let me know if you need any more information.
Thanks in advance for your time,

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

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.

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.

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.

Oracle RDF and Oracle Business Rules & Protege

A couple of questions:
1.) Has anyone used Protege to create frame-based ontologies which can somehow be used with Oracle Business Rules?
2.) Has anyone used Protege along with the RDF storage functionality in Oracle?
Thanks.

Melli,
I just started with semantic so won't have many useful ideas for at least some time.
mostly there will be bugs and misunderstanding on my part.
At this point i do see that the supplied library is not working properly . see my other thread. Fixing that would be really helpful.
Let me know
As of Composer - well let's just say its cost ineffective for organization to use on pilot project..

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.

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.

Xpath and oracle business rules

Hi; are there any examples that demonstrate using XPath in a rule?
Any comments on whether oracle business rules might be a valid choice for an application that needs to enforce a set of, and varying, constraints on an incoming XML document.
Thanks for the info.
-Tim Watson

The XPath support in the current version of Rules is for asserting portions (or all) of an XML document as facts. The Rules are then written against the elements in the XML that you are interested in.
I can't say for sure without more details, but Rules would work for enforcing constraints on XML documents.

Oracle Business Rules Custom Functions

Hi,
I have an input fact with attributes A,B,C & D and an output fact with E, C & D. (C & D attributes are common in both facts)
Whenever the rule matches, we are asserting new output fact by assigning a constant value to attribute 'E' and also the transactional values to C & D using input fact's C & D attributes.
This way, we are making sure to return the response with matched transactional values.
But we would like to do this by writing a custom function so that user need not assign this mapping manually whenever any new rule creates. User just assigns the constant value to attribute E but values to C & D attributes should be assigned automatically.
Please let me know your suggestions on this.
Regards,
KK

Hi Subha,
Please find the answers inline :
1. In Oracle Business Rules, can one rule invoke another rule?
-- > Yes, once a rule gets executed, it might create more facts, that in turn fire another rule. It all runs around the inout/output facts.
2. Can we make two rule sets dependent on each other?
-- > Yes
3. Can we return data of types String, Boolean, Integer, Double from a rule execution?
-- > Yes, you can use java code with functions.
4. Can we build complex logical AND, OR assertions in Oracle rules?
-- > Java programming language is needed for this..
5. Can we use custom business objects (not Java data types) within a rule?
-- > Dont think so
Regards
Anirudh Pucha
