Oracle business rules and backchaining
Hi,
Does Oracle Business Rules support backchaining, as Jess does?
Cheers,
No, not in 10.1.3 and not in the first planned 11 release. It is on the list of candidate features for future releases.

JHeadstart, Oracle Business Rules and BPEL Process Manager
Dear JHeadstart Team,
I have some questions regarding integration of JHeadstart and Oracle Business Rules and Oracle BPEL Process Manager. As a matter of fact I don't have any work expriences with these tools so my questions may not be good and precise.
1- Using a business rule engine can dramatically increase speed of development and ease of maintenance.I had a very good exprience in using JHeadstart and Headstart in the past but I wanted to know if it is possible to use Oracle Business Rules in conjunction with the JHeadstart ? If so, What steps should be taken? Is there any known issue about this integration? Does Oracle Business Rules have any interference with JHeadstart or it is only used in model layer during insert,update,delete?
2- Is it possible to develope a system based on oracle work flow engine (Oracle BPEL Process Manager) using JHeadstart ? If so, What steps should be taken and how the changes in the flow of work would by applyed in a system developed by JHeadstart. Is there any known issue about this integration?
Any help,link to documents or general guidelines would be highly appreciated.
Thanks in advance,
NavidCouple of things I would like to add, are the following.
In the context of an ADF application usage of Oracle Business Rules most likely is in the business logic layer, but mind that it does not need to be restricted to that.
Oracle Business Rules takes so called 'facts' as input, evaluates some rules based on that and change those facts or return some result. That might be checking a business rule as defined in the JHeadstart Developers Guide. But it might also return some value that is used in a navigation rule.
Think about a page flow where after page A normally page C is presentend, but in case of some situation (like a customer ordered something and you want to present some special offering based on that) you want page B presented in between (i.e. A -> B -> C). Oracle Rules could be used to determine this page flow. This would be an example of using it in the controller layer (probably in combination with using facts that come from the model layer).
Another remark that I would like to make, is that in my opinion it does not make much sense to use Oracle Rules for business rules that logically more or less are part of your data model (like end date must be on or after begin date). You typically use Oracle Rules to implement business rules that are of a volatile nature, meaning that day-to-day business may require a change of the rules. One example is the navigation case that I mentioned before. Another (typical) example would be a rule that defines when a customer is a Gold customer.

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

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 WatsonThe 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. -

Hi, I have a question that hopefully someone can give light to.
Our current requirement for an ODI solution is to have business users create or edit rules (not just table constraints, but actual complex business process rules) that they would like to apply to the data during integration. I was thinking of two possibilities for this:
1. Load a rule file in ODI and then execute the rules in ODI.
2. Use Oracle Business Rule.
Between the two options, which is most likely possible? I have yet to fully explore ODI so I'm not sure if both of these options are feasible. If not, can someone give me sound ideas to work on for this requirement?
Thanks,

Ruleauthor.ear and rulehelp.ear for Oracle Business Rules
I'm following the instructions for installing Oracle Business Rules in Standalone OC4J. The instructions say you need to get files (in the subject line of this thread) from the full Oracle App Server install.
This was a bit of a surprise because I'm interested in running OBR without installing the full 10.1.3 App Server (which is, of course, why I'm following the instructions to install on Standalone OC4J).
The files are in the Oracle App Server install directory (for "Disk 1") inside this file:
..\stage\Components\oracle.rules\10.1.3.0.0\1\DataFiles\common.jarMy question is: are there any other dependencies to the full Oracle App Server for running Oracle Business Rules in a Standalone OC4J?

Anybody here knows the difference between Business Rules and BPM..
We can do pretty much everything with a Business Rules Engine as we would do with BPM , then in which scenario should we use BPM and in which scenario should we use Business Rules Engine?
Ofcourse Business Rules Engine has more complex set of rules than any BPM product in the market for .eg. ILOG Business Rules...BPM and a rules engine are different. Both are important, but they have different uses.
Oracle BPM Studio is used by Business Analysts and Developers to model processes, integrate underlying components (including business rules) and develop user interfaces.
There's an Engine that executes the processes that have been modeled. It sends the work item instances to the right person or persons with the right data when the work item reaches an interactive activity in the process. Similarly the Engine has invokes the underlying components specified in the process when the work item instance reaches an automatic activity.
There's an out of the box Workspace runtime that lets end users manage and run their work item instances as they flow throughout the processes.
We can business rules inside the processes, but one does not replace the other.

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

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 Business Rule OBR SOA Suite 11.1.1.3.0
Hi,
I have created a business rule and used it in my BPEL process. The business rule example is as follow
<code> if the state is va then give 10% discount<code>
If I need to change it to 25%
Then I would modify the business rule via jdev and redeploy the composite application.
Question. How can I modify the business rule through the EM?
I need to modify the rule values without using jdev and redeploying the composite.
Thanks

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, SriniIgor 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.
