Oracle Business Rules with Fusion Release 4

Hi
I am wondering if we can use the Oracle Business Rules product with the Oracle Fusion Compensation APplication Release 4.
Thanks
Srinivasa Sunchu

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

I looked through the source code of one of our products that uses the Rules SDK to see if there is an easy-to-extract example, but it's far beyond the scope of a forum post. 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.

Unable to integarte Oracle business rules with BPEL

hi'
I am unable to integrate Business rules with BPEL, I am using JDeveloper to do this.
I have successfully made a connection to rule repository and using decision service in synchronous BPEL process.
In the decision service wizard step 1 of 2
1.) Selected 'Execute Ruleset' in Invocation pattern
2.) Selected rules set which I have cretead before.
the problem is coming when nothing is geting displayed in the
window below for Fact name, assert name, watch fact.
please help me why Fact name, assert name, watch fact are not coming.
thanks
Yatan

Thanks Anirudh,
Do I need to make some changes in the java classes or in the XSD file which I am importing while creating new BPEL process
I am importing the same XSD file in input and output, actually I am updating the database in the BPEL process so I am taking the
input from the payload and updating the DB.
Do I need to make two different <complexType name="updatingDB"> and <complexType name="businessrules">in the XSD
if you have some example which shows the Integration of BPEL and Business rules
with Java facts please share it with me.
thanks
Yatan

Using third party jars with Oracle Business Rules

Hi
I am working on Oracle AS 10g release 2.
We are using Oracle Business Rules in integration with Oracle BPEL.
While using third party jars however, Oracle Business Rules end is facing errors.
Error during unmarshallingProvider com.sun.xml.bind.ContextFactory_1_0_1 not found
oracle.classloader.util.AnnotatedClassNotFoundException:
Missing class: com.sun.xml.bind.ContextFactory_1_0_1

Can anybody help in figuring out where Jaxb jars(3rd party jars) are to be kept so that OAS access it?
We tried using the applib folder to load the jars but we are getting class loading errors.
When new instances are created, class loading is not happening.
Pls help.
Thanks

Are you using Application Server Release 3 or Release 2? There are different versions listed in your mail.
I think you probably want to add this as a shared library via EM and then import the shared library to your application with the application's xml config files.

Upgrade Business rules with Calc Manager

Hello Gurus,
Recently performed an upgrade from 11.1.1.3 to 11.1.2.2 by replicating the Database to a new database machine.
I had Business rules in 11.1.1.3 and did not perform any steps to migrate the rules to Calculation manager in 11.1.2.2
The doubt I have is,
1. Are the business rules automatically upgraded when performing upgrade by EPM system configurator (since the database is replicated)
2. If so, how do I see the business rules in 11.1.2.2 environment? How can I use migrate feature option.
Thanks
HyperionEPM.

From 11.1.2.2 documentation:
Upgrade Wizard
If your application used Oracle Hyperion Business Rules, the Upgrade Wizard automatically converts Business Rules business rules to Oracle Hyperion Calculation Manager business rules. Release 11.1.2.2 supports onlyBusiness Rules business rules as the calculation module.
Notes:
•Classic application administration is now called Oracle Hyperion Planning application administration (versus Oracle Hyperion EPM Architect application administration).
•The Upgrade Wizard automatically upgrades applications having Oracle Hyperion Business Rules business rules, converting them to Calculation Manager business rules. However, the Upgrade Wizard does not automatically convert Release 11.1.2.1 applications having Oracle Hyperion Calculation Manager business rules. For those upgrade instructions, see the Oracle Enterprise Performance Management System Installation and Configuration Guide.
Business Rules Maintenance Release and Upgrade Installation PrerequisitesIf you are using Business Rules, you must migrate to Calculation Manager rules in Release 11.1.2.2. Before migrating business rules, you must perform prerequisite tasks. Note that these tasks are required if you are applying the maintenance release or if you are upgrading.
To prepare to migrate Business Rules, perform the following tasks in your current Business Rules environment before installing Release 11.1.2.2:
1.in Business Rules, within the Rule Editor, remove the associated outline (that is, the design time location) from each business rule. After you do this, the Associated Outline drop-down list should display the text, Select Outline.
2.On the Locations tab of the Rule Editor, ensure that each business rule has a valid launch location, which must be an absolute location. Although “All Locations” is valid in Business Rules, when you migrate business rules, you must provide the details of a specific launch location (that is, the application type---Planning or Essbase, the server name, the application name, and the database or plan type). If you want a business rule to be valid for multiple launch locations, you must provide the details for each location. The locations must be in different applications; you cannot migrate the same business rule to different plan types in the same application within Calculation Manager.
If the rule is a part of a sequence, then the launch location of the rule within the sequence must be one of the launch locations listed in the Locations tab of the rule.
3.On the Access Privileges tab of the Rule Editor, ensure that each business rule has security defined for a specific location or locations and not “All Locations.” If multiple locations are defined for a business rule on its Locations tab, you must add security for each location individually.
4.Do not modify rules in Calculation Manager until migration is completed.
5.If you are using Business Rules with Planning, as a precaution, create a backup of the rules: Use Administration Services to export the rules to XML in Business Rules format. If you are upgrading from 11.1.1.3 or 11.1.1.4, also export the rules to Calculation Manager format. EPM System Configurator exports the rules during database configuration for use during application upgrade.
6.If you are an Essbase-only Business Rules user, you must export business rules. To export the Essbase rule from Business Rules:
a.From Administration Services Console, right-click the Business Rules node and select Export.
b.Export the rules in Business Rules format and then select all of the Essbase rules in the repository. If you are upgrading from 11.1.1.3 or 11.1.1.4, also export the rules to Calculation Manager format.
c.Specify the location to save the XML file, and then click OK. If you are upgrading, the location should be a shared drive that is accessible from the upgraded environment.
Make a note of the location. You import the file later in the process.
Migrating Business Rules to Calculation Manager for use with Planning
If you applied the maintenance release to move from Planning Release 11.1.2.0 or 11.1.2.1 to Release 11.1.2.2, and you were using Business Rules rules, you must migrate the rules to Calculation Manager rules.
Before you migrate, ensure that user directories and native users with the same SID are available when you upgrade Shared Services.
Ensure that the Planning applications are upgraded to the current release and are available in Calculation Manager under SYSTEM View.
To migrate Business Rules rules to Calculation Manager rules:
1.In Calculation Manager, select the migrated Planning application, and then select Migrate.
The data that was exported during database configuration with EPM System Configurator is imported to Calculation Manager.
2.Repeat for each Planning application.
3.Deploy the rules from Calculation Manager to Planning. See the Oracle Hyperion Calculation Manager Designer's Guide.
After migrating business rules and rules security, if any of the rules had multiple launch locations and you migrated to more than one location, Calculation Manager creates a rule for the first migration, and shortcuts for all subsequent migrations. If the rule had rule-level variables, for the shortcuts that are created in the application in the new environment , its variables are moved to the Plan level. In this scenario, test rules in your environment to ensure that they work as expected.
If you still have problems, raise an SR and we can get on a call to figure out why the rules are not coming over.

OPA & Oracle Business Rules

Can any one provide me the basic difference between OPA & Oracle Business Rules
The difference between "OPA & Oracle Business Rules" link or document will help me a lot.

OBR is a tool that is part of Oracle Fusion Middleware.

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.

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.

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

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,
Navid

Couple 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 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.
