Business Rules Engine (BRE) is this really a true business user's tool?

The primary need for business/information/non-technical users is to be able to create, edit, delete, enable, disable rules once developed (vocabulary) & deployed by the developer. Is it possible? If possible then how &
by using which tool or UI of Biztalk server?
For the batch process, if each input record from flat file can be match with the 50 million records in Sql server, then what would be the performance?

What all needed at client machine to make use of Business Rules Composer for 10 machines?
Non-technical users is able to create, edit, delete,
enable, disable rules using Business Rules Composer, is it possible?

Business rules engine faults..

Can someone please advise on what could cause this issue?
We are using SOA suite 11.1.1.2
1. The rules engine takes an input as usual but doesn't send any output.
2. The BPEL process that invokes the rules sends out a bpelFault instead - (because the rules engine doesn't send anything back)
<bpelFault>

Hi Paul:
The short answer is yes. But its not easy.
You will have to add some references to your orchestration:
System.Transactions.DLL, System.Data.DLL, Microsoft.RuleEngine.DLL
Next the BRE will need a connection string to connect to your database.
Create a Variable in the orchestration ex: SQLConn of type System.Data.SqlClient.SqlConnection
Create a Variable in the orchestration ex: RulesConn of type Microsoft.RuleEngine.DataConnection
in an expression shape set the following :
SQLConn = new System.Data.SqlClient.SqlConnection("Initial Catalog=Customer;Data Source=(local);Integrated Security=SSPI;");
RulesConn = new Microsoft.RuleEngine.DataConnection ("database", "tablename", SQLConn);
then call the rules shape.... it should work.
there is a blog post about this I have used in the past:

Hi Dilip,
Recommend you to refer this Technet article: High
CPU When Executing a Business Rules Engine (BRE) Policy
Also refer the post: RuleSetTranslationComplexityException
- Scenario...
You need to Increase the time out in the registry for the rules engine (Translation Timeout) from 1 minute ("60000") which
is default to higher value, something like 5 minutes.There is no performance impact of increasing this value.
This setting can be set in the registry or a .config file. The registry settings are global for all applications that host a rule engine instance.
Registry location:
32-bit server:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\BusinessRules\3.0
64-bit server: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\BusinessRules\3.0
Setting these values in an application configuration file will override the values in the registry. If the policy is being executed within an IIS worker process, the web.config file
can be modified. If the policy is being executed within a BizTalk orchestration, the BTSNTSvc.exe.config or BTSNTSvc64.exe.config file can modified.

Using Rules Engines, & Batch jobs

So, we're looking into the best method for storing our business rules. So far, we're investigating Rules Engines (Drools), using database Triggers, SOA, or coding those rules into the application itself.
Currently, the bulk of our business rules are in table triggers. So, when our batch jobs execute, they pick up all of the business rules as they go.
I like the concept of using a Rules Engine, though, especially if we could give some control over maintaining those rules to the customer.
So here's my question, if we went to a Rules Engine approach, or chose one of the non-Trigger approaches, would our batch jobs now have to plug into those rules that applied to that particular process? I'm worried about losing those automatic business rule checks when the trigger executes for any interaction with the underlying table data. With a rules engine, it would seem, you'd have more planning b/c the batch job now has to call all rules that may apply.
Am I missing the point of a Rules Engine, or is this the case?
--=Chuck

1) Oracle 10g includes a rules engine, so if you're going do that path, I'd consider strongly keeping everything in Oracle.
2) What is the nature of the business rules? Are these validations? Calculations? Something else?
3) Depending on the rules, and whether your batch process has to do anything to react to a rule (i.e. if you have a validation rule that indicates the batch job inserted an invalid entry, does the job need to do something? Or could a subsequent query alert the user to the problem), you can generally have the rules engine run all the rules at the end of the load (that's generally 1 command from the batch process to the rules engine). Or you could have the rules engine run everything periodically. With the internal Oracle rules engine, I believe you can also have things evaluate synchronously.

WL Portal 7.0 Rule Engine

How do I customize the Rules using the Rule engine that comes with Weblogic Portal 7.0? I would like to use these Rules not for Personalization but drive my application flow.
Where is the grammer for the Rules, if I want to build by hand?
Any help would be appreciated.
Bob

Bob,
I haven't seen docs that define rule grammers etc. However, you can interact with
the rule engine using either adviselet api or the rule engine api. You can amuse
yourself at http://edocs.bea.com/wlp/docs70/javadoc/index.html for WLP 7.0 for
e.g. Look into the APIs for RuleParser, RulesManager, RulesAdviceletImpl etc.
I've done work on this at the adviselet level (the one that actually gives advice)
to use thrid party rule engines etc., but hasn't customized rule engine itself
in lines of for e.g., getting rules from other rule engines and importing them
to WLP rule engine.
Hope this helps,

Rules Engine Design Questions

Rules Engine Questions:
1. Rules are processed in the order they are created in dictionary file if the priorities are the same. Is it true?
for eg: if the order you see on the screen in rules dictionary window is:
     rule1 --> set var1 = 10
     rule2 --> set var1 = 20
     rule3 --> set var1 = 30
     rule4 --> set var1 = 40
     rule5 --> set var1 = 50
     result would be 50
2. I want to use the rules engine for validations.
Eg: Can we check for the requiredness of xsd validations using rules engine? or this should be done else where?
eg:
If my xml is below, then can I use rules engine to check
<Firstname>
<LastName> and
<Address1>
for emptyness and pass back saying that the validation failed because <LastName> and <Address1> are empty.
<Customer>
     <Firstname>aaa<Firstname>
     <LastName> <LastName>
     <Email>ccc<Email>
     <Address>
          <Address1> </Address>
     </Address>
I have a response xml:
     <ValidationResult>
          <Result>Failed<Result>
          <Message>all required fields are not present<Message>
     <ValidationResult>
So my rules should be
     check for <Firstname>
          Assert new ValidationResult ('success', ..)
     check for <LastName>
          Assert new ValidationResult ('failed', ..)
     check for <Email>
          Assert new ValidationResult ('success', ..)
     check for <Address1>
          Assert new ValidationResult ('failed', ..)
and since last rule is failed, will rules engine send back failed? or what is the strategy for order of rules that get fired?
For the above scenario what would be the best design solution?

This is a complicated question but I will try my best to give you the best solution:
#In answer to your question regarding the order that rules fire unless you use priority you cannot garantee the order that the rules fire. The Oracle rules engine uses the Rete algorithm to establish the order in which to fire the rules and this is generally based upon the data passed into the rules. Therefore if the result of rule 4 may effect rule 1 then the rules engine will run rule 4 before rule 1.
The scenario you have provided is slightly different however and I woudl suggest the following.
Instead of passing out a single result from your ruleset pass our an array of results meaning you could effectively run all your rules and pass out all rules that failed. Be wary of checking for nulls however because if nothing is passed into a field then the rules engine will not create that element in the rules fact and the rule will never fire.
To create a array of results you will need to create a function which creates the result fact for you and then addes each result in turn.
If you woudl like more information let me know and I will help out as much as I can.

Haley Rules Engine - HaleyAuthority with respect to Oracle E Business Suite

I am currently exploring on Haley Rules Engine which is recently aquired by Oracle.
As per my investingation, i came to know that HaleyAuthority ruleEngine is available as plugin from the recent release of Siebel CRM 8.0 installation and onwards.
Here goes my questions
1) is this haleyAuthority rule engine available as third party tool? If so, How to integrate with Oracle E- Business Suite.
2) Like Siebel 8.0, Is this HaleyAuthority plugged in any latest version of our oracle E- Business Suite?
Please let me know your understanding and information on Haley Rules Engine with respect to Oracle E-Business Suite.
Thanks in Advance.

Praveen ,
May be late for you (but for others looking similar information)
haleyAuthority is different from Haley Determination Services (now Oracle Policy Automation)
OPA (Haley's Determination Services) are available as Web Service which you can invoke from E-Business Suite or Use Fusion Middleware (SOA Suite / BPEL) as layer between OPA and E-Business Suite

Business Rule Error: Fact not found in the rule engine working memory, rule

I am trying to create a simple decision table with an input(ValidateInput) and a output(ValidateOutput). The input and output schemas have unbounded and nested elements(Parent-child relationship). When I create a condition(specific condition on input) and in the action I am asserting the output object. But when I run using EM it throws the following exception. It would be helpful if somebody could tell me what could be the problem. Please note when I set the output as ValidateInput object then it runs fine. Also it executes fine with ValidateOutput if it doesn't have unbounded(List) element inside it.

Business Rules Engines?

Hi,
I have experience with embedding "CLIPS" which is a C rules engine as a
Forte Service Object which was easily wrappered using standard Forte
wrapper strategy.
Also, we have a sales rep in ATL who used to work @ ILOG and therefore
competed with Nueron Data, and from various conversations with mutual Forte
/ Rules Engine customers I've learned it would be a complimentary integration.
They all have some C-callable API and so a Forte Service Object would be a
good client to the rules engine api due to our support for multi-threading
when API is thread safe and additional option of replicating for load-bal
when API isn't thread safe. The later concept is analogous to our use of
DBSession object for interface with DBMS client api's.
Be aware, the experiences I hear about with the mentioned rules engines is
that there are not always business analysts truly capable of using the
Rules development interfaces provided by the tools.
So maybe the use of Forte Conductor's dynamic Process automation
capabilities may also be a fit. If you want to discuss how, let me know.

[Business Rules] Rules engine not updating my Fact Result as expected.

I have a Fact type implemented as a Java class, named Commission with the following properties: age(int), area(int), amt(double):
In the Java application I set the age to 30 and area to 3:
Commission comm = new Commission();
comm.setAge(30);
comm.setArea(3)Now I have a set of rules defined in the ruleAuthor where in, if the age is > 20 and area is between 1 and 5 then the business rule engine should set the Amt field to .3
But when I run the rules engine:
ruleSession.executeRuleset(...);
ruleSession.callFunctionWithArgument("assert", comm);
ruleSession.callFunction("run");
double commamt = comm.getAmt(); //this value returns (0) as if the rules engine did not fire the rule and did not change the amt field to .3When i get the comm.getAmt(), the value is zero and not 0.3 which is the expected result.
I wonder what's wrong, I only followed and patterned the instructions and code that came with Oracle Business Rules CarRental Example and/or the example that came in the Business Rule ViewLet.

Hi Phil,
I tried your suggestion. But it still does not work.
I don't if this would help but this is how I defined my rules:
1. I created a Java class file as a Fact Definition. Compiled it and stored it into a jar file.
2. Copied the .jar file to a remote machine where OracleAS is installed.
3. I run the ruleAuthor (browser) and specified a ruleRepository file.
4. Specified the jar file where the Fact Definition (Java file) is.
5. Created Ruleset and Rules
6. Save the Dictionary.
7. Copied the generated rulesRepository on to my local hard drive (remote).
8. Create and Run the Rule-Enabled Java application. ruleRepository points to the ruleRepository file generated by ruleAuthor and copied to my local hard drive.
Maybe there is something wrong with how I packaged the Java Fact Definition?

Business rules Engine

I have a system dealing with different work flow engines at the same time. It gets data from a whole list of different applications, Once it recieves this information, it processes it based on a Business Rules Engine. The rules for the Busines Rules Engine are defined in a definition filw which is huge and deals with info as to how to handle a particular piece of data under a certain situation. Would you send it to System A, B or X based on some information and what kind of operation needs to be carried out.
Now this seems to be a decoupled system since theis system acts like an Enterprise bus or a hub and is decoupled from the rest of the systems. Its technological dependencies on the rest are minimal. But the problem as in any mediator based pattern is that if the definition file is messed up, the rules def file, all the systems getting info from the hub would be messed up.
Could someone advise how to avoid this dependency, which is more of a business rules dependency than technological.

"messed up" as in one or more bits flipped? or as in those rules are
incorrect? Flipped bits can quite adequately be detected by some form
of CRC. Incorrect rules are much more difficult to detect.
kind regards,
Jos

Does sap xi has business rules engine?

Dear experts,
i am dealing with microsoft biztalk server,i come across this business rules engine.this framework comprises policies,facts,vocabularies, and rules.
so does <b>sap xi </b>has this business rules engine??if yes plz eloborate?? if no whats the sap's alternate for this??
thanks heaps in advance
cheers
kish

well alternative would to develop some web page or ABAP screen which you can fromulate rule and in background you can use R3 Custom tables or any database tables to store the rules...
while mapping you can do RFC lookup in case you have used R3 tables or database lookup to read the rule in case of other database....
look possible but we have yet started working on this approach..

When i had this issue i overcame it by opening the Rule Editor->Deleting all existing facts that are imported->Close JDeveloper -> Delete the contents of .rulesdesigner directory in your workspace -> Restart JDeveloper -> Reopen Rule designer and re import all facts.
Also make sure that all the schemas that are used for Facts are valid ones.

Rules engine can't find classes in DM

I am working with the Oracle rules engine and can't get around what seems like a simple problem. I am following the example in chapter 18 of the BPEL developers guide (http://download-east.oracle.com/docs/cd/B31017_01/integrate.1013/b28981/decision.htm#sthref3129) and can't seem to run the rules.
I am creating the DM using the CreditRating.xsd provided in the example. I have created the RL function and ruleset as stated in the chapter. When I go to the RL tab and click on check RL syntax I get the following error:
A syntax error is found.
Error:'creditrating.RatingType' is undefined at line 4 column 14 in DM
1. ruleset DM
2.
3. {
4. fact class creditrating.RatingType supports xpath; <<<<
5. fact class creditrating.Rating supports xpath;
6. fact class creditrating.RatingrequestType supports xpath;
I also have a process that uses a decision node to execute the ruleset and it complains that the creditrating.objectFactory is undefined. I have to be missing a step somewhere that actually links in the classes that are auto-generated by JAXB.
Any help is greatly appreciated.
Thanks,
Chris

I dug a little deeper and figured out what the gotcha is with the rules engine repository. So, when working with the rules engine there are two ways to access the repository file that holds the data model and business rules. You can either access the file directly from the hard drive or through the use of WebDAV.
I was using the rules author to access the repository directly on the hard drive since I didn't have WebDAV setup somewhere. I created my data model and my rules using the rules author.
As part of creating the BPEL process to use the rules in the repository, I created a Decision Service and pointed it at the repository file on the hard drive that I have been editing with the rules author. The act of doing this COPIES the repository to the JDev directory where the Decision Service resides.
During the deployment process, the Decision Service is deployed (auto-magically) as a separate ear file to the app server. This Decision Service ear file contains yet another copy of the rules engine repository file. The repository in the ear file, of course, is the repository that the BPEL server executes rules against when the BPEL process is run.
Needless to say, continuing to edit the original repository that you were editing with the rules author does not actually affect any of the rules that are running on the app server. There are a couple of ways that you can get around this:
1.) Edit the repository file (with the rules author) in the JDev directory directly and after making any changes save the repository and redeploy the BPEL process. Redeploying the BPEL process will redeploy the decision service which contains that copy of the repository.
2.) This one is not really recommended, but is an option. Edit the repository file that got deployed as part of the decision service deployment. This will make your rules changes effective immediately. One of the real big problems with doing this is when the BPEL process is redeployed the repository on the app server that you have been modifying will be overwritten.
3.) The real solution to this problem seems to be setting up a WebDAV deployment somewhere that you and the app server has access to.

Custom Rules Engine

Is there a good pattern that I could follow to create my own rules engine. My requirement is that I have a lot of business rules, but since they are kind of static I don't see the need to use a rules engine. These rules don't change and I need high performance. I want to write my own custom rules engine. Are there any sample designs or code that is available anywhere or could someone suggest how I should go about creating my own rules engine which can be maintained easily and also allows some flexibility.
Thanks
aaugusty

Hi aaugusty,
My requirement is that I have a lot of business rules, but since they are kind of static I don't see the need to use a rules engine. These rules don't change and I need high performance.
The default thinking of Rules has been usage of XML. So that we separate the static data from logic. Although the rules are etched in stone, they are easily readable and editable.
I want to write my own custom rules engine.
Persoanally written/owned rules engine means maintenance cost is more. Performance will be more at the start. Might deteriorate during maintenance.
Are there any sample designs or code that is available anywhere
A search in google got me a lot of links. See if you find this useful
http://www.fawcette.com/javapro/2003_08/online/xml_yboglaev_08_01_03/
Looks like java has a Rule Engine API as a R&D work.
or could someone suggest how I should go about creating my own rules engine
The above answer holds good for this too.
which can be maintained easily and also allows some flexibility. "
I tried to do something like this using only java code. After finishing the voluminous work. I was given a lateral thinking of using a script engine!!!!! What I say could be non conventional, but its really a crisp work. You can have rules data coming from XML and java scriptlets doing all of the simple logics using those data. Processing of your data and script is done by a Script engine. The output may be in xml. There are Script Engines available for download. That satisfies your requirement of creating, maintaing and operating RULES. There need not be an engine at all. And not much java too. Easy to manitain and higly flexible. Because you are using only xml and scripts.
Good luck.
