Architecture for Rules Engine

We are reengeneering our existing VB rule engine to Java based. Any input for the architecture is appreciated. Rule engine should fit into distributed arch (including clustering). Here is one suggestion I have.
1. Stateless -Entity beans. No stateful
Any other arch suggestion is appreciated.
Thanks

Hi Mahesh,
According to log file, I find the message ‘The setup100.exe.config file was not found, therefore the DTSWizard and SQLWatson app config files were not replaced’. It seems that the SQL Server setup file is not complete. Please check that if the SQL Server
setup file is corrupted, if it is corrupted, please download it again and reinstall SQL Server 2008 R2.
However, if there’s no problem with the setup file, please check that if there is third-party software such as anti-virus software on your computer blocking the process of SQL Server installation. In addition, make sure that you choose ‘Run as administrator’
to launch the setup and configure SQL Server service accounts appropriately with administrator permission during the installation.
For more details about this error, please review the following similar thread.

Rules Engine Environment in MDM

Hi Everyone,
I am evaluating the capability of SAP MDM to see if there is any kind of rules engine delivered that can create a material master (SKU) number. I am not trying to create material master records yet - just the material number !
Background:
Defned rules, coupled with reference data should be able to generated the list of SKUs.
Example:
Reference Data contained in 3 tables:
Product Line: LN1, LN2
Release: 2009
Language: EN, JA, FR, DE
SKU mask: AA-BB-CC
AA = Product Line
BB = Release
CC = Language
The rules would be to create combinations of all the reference data values and output a list of SKUs according to the SKU mask/format. In other words, by implmenting rules, I should be able to generate 2x1x4 = 8 SKUs in total (2 values for product line, mulitplied by 1 value for Release, multiplied by 4 values for Language).
Questions:
I know I can implment rules on the ABAP workbench in R/3 to create material master numbers, and then later create actual material master records with reference to other materials all within R/3. However, I would like to create and manage the material master directly in MDM.
1) Is a rules engine like drools provided as part of MDM?
2) Since MDM is based on the Netweaver and sits on the web apps server, is there an ABAP workbench provided in MDM from where I can create the rules and create z tables for the reference data.
3) Do I need to create a separate web service in Netweaver Developer Studio to create these rules.
Thanks in advance
-Rajiv

Hi Rajiv,
In some scenarios Material master is imported to SAP MDM from R/3 and all the logic is performed in R/3 itself. For such cases You can use the standrad MDM Material Repository provided by SAP.
<i>How do people create specific part numbers (material numbers / SKUs) in SAP MDM based upon some specific business logic?</i>
Let us say the Part number is an depandant on another field say Product ID.
In MDM Console you can specify the business logic in the Calculation field.
Also i would like to add that in SAP MDM most of this business logic are mere mathematical fuctions (part no = 1.5 * product ID). There is no provision to call external methods (like RFCs in R/3).
I suggest you to get the Standard MDM Materials Repository and play around the Calculated fields\ Auto ID Fields in MDM Console.
Get back for help,
Vijay

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

How to use Hashtable in Rules Engine. And objects within objects in rules

This is something to do with the JBoss Rules Engine.
I have an object called 'Employee' containing variables name(string), age(int), sex(string), an object Skill and other fields not relevant.
Now the Skill object contains name and desc as variables.
And now i have another seperate object called Test containing two hashtable: inputHT and outputHT.
i have appropriate data in each of the objects and the hashtable:
Employee e = new Employee();
e.setName("Name");
e.setAge(18);
e.setSex("f");
e.getSkill().setSkill("Trainer");
Hashtable ht = new Hashtable();
ht.put("age", new Integer(e.getAge());
ht.put("sex", e.getSex());
Test t = new Test();
t.setInputHT(ht);
Since this is something to do with drools rules: I have the appropriate code even for that.
Like obtaining the rules defined(.drl files) in a stream, constructing the package builder, rulebase and the working memory.
I will now explain u my .drl files(ie the rules that i have defined) and the error that i am encountering
when I have the rule as the following there is no error:
rule "testRule1"
when
e:Employee(age >= 18, sex == "f")
then
System.out.println("The lady can marry");
end
In the above rule we can see that only two simple variables contained in the employee object is being accessed and there is no error encountered.
But when I try to access the object "skill" in the employee object, the rule throws me an error when i am constructing the packageBuilder:
rule "testRule2"
when
e:Employee(skill.name == "Trainer")
then
System.out.println("The skill is trainer");
end
The error thrown is : unexpected token 'skill' and many other dump errors and also error: expected token ')'
I tried changing the when clause as the following:
when
e:Employee(skill.getName() == "Trainer")
and also
when
e:Employee(skill.getName().equals("Trainer"))
All of them throws the same above error.
But at the same time if i access only object without its variables, it is working fine. Like:
rule "testRule2"
when
e:Employee(skill == "Trainer")
then
System.out.println("The skill is trainer");
end
The above rule works properly and does not throw any error. But it is not a valid rule. But syntactically it is correct. and does not throw any error during packageBuilder.
Similarly, the problem is with the Hashtable
The below code works fine, but rulewise it is not valid, but syntactically correct. and does not throw any error
rule "testHT1"
when
t:Test(inputHT == "f")
then
System.out.println("Print this");
end
But the following code throws error, telling unexpected token 'inputHT' :
rule "testHT1"
when
t:Test(inputHT.get("sex") == "f")
then
System.out.println("Lady");
end
I even changed the when clause, but did not get the appropriate result and it threw me error.
when
t:Test(((String)input.get("sex")) == "f")
and also many other variants but of no use.
It would be of great help if u or anyone else could reply to this with some solution
Thank you in advance

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.

Has anyone on this list integrated a COTS business rules engine,
or components, into a Forte application? Specific products
of interest would be those from Neuron Data, ILOG, USoft
or, possibly, Vision Software.
If so, comments? Type of application? War stories?
Thanks.

Oracle Bussiness rules - Can we download and use rule engine independently

Hello ,
I have seen and used oracle business rules with SOA and BPM projects , but recently one of the client requested to see if we can download and use oracle rules engine independently .
Does anyone have any idea if it possible ? Have checked oracle downloads and it says OBR 11g is part of SOA or BPM suite .
Thanks in advance
Rupesh

Thanks for the reply Arun .
So just to reconfirm if a client wants to use Oracle Business rules they would need to buy license either of SOA suite or BPM suite ?

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>
<faultType>
<message>0</message>
</faultType>
<selectionFailure>
<part name="summary" >
<summary>empty variable/expression result. The XPath variable or expression /ns1:callFunctionStatelessDecision/ns1:resultList/ns2:RulesResponse is empty at line 122. An attempt to read or copy data referenced or computed by the XPath expression either had invalid data, according to the XML schema, or did not contain certain optional data. Ensure that the variable or expression result named in the error message is not empty. Enable XML schema validation of related variables to ensure the run-time data is valid. </summary>
</part>
</selectionFailure>
</bpelFault> 3. At other times, the process works fine for the SAME input

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:

Fact not found in the rule engine working memory,rule session executionfail

Hi
I'm getting this error on my BRE, the instance Id shows 'faulted' but other consectuctive web services are 'completed' successfully.
please advise how to fix it.
Error Message: {http://xmlns.oracle.com/zz_ValidationRules/zz_ValidationRules_DecisionService_1}operationErroredFault
Fault ID rules:417
Fault Time Aug 25, 2011 4:59:39 PM
Non Recoverable Business Fault :
Fact not found in the rule engine working memory, rule session execution failed. The rule session 130287 failed because an instance of the fact Response could not be found in the working memory of the rule session. This is most likely a rule modeling error. The decision service interaction expects the fact instance to exist in the working memory of the rule session. Check the rule actions in rule designer and make sure that a fact of the expected type is being asserted. If the error persists, contact Oracle Support Services. 130287
thanks,

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.

Fact Not Found in Rule engine working memory

I am using 11g, I have built a Business Rule, using RL facts, XML facts, Bucketsets and multiple Rulesets which internally has decision table and If-then rules. After deploying the same, Business rules runs successfully for some conditions and faults for some condition. The fault error for those failed conditions displays the following error:
Fact not found in the rule engine working memory, rule session execution failed. The rule session bpel:<somenumber> failed because an instance of the fact <factname> could not be found in the working memory of the rule session. This is most likely a rule modeling error. The decision service interaction expects the fact instance to exist in the working memory of the rule session. Check the rule actions in rule designer and make sure that a fact of the expected type is being asserted. Contact oracle support if error is not fixable.
It is wierd becuase if it is a fault with respect to working memory then I would imagine it has to fail for all the conditions as all the conditions assert the same Object. Has anyone faced the same issue or am I doing something wrong here.

I deleted the RL facts that I had created and asserted the result to the Business Object, this seems to have taken care of this issue, but I am still not sure what was wrong in the way I build the rules using RL.Hope this helps.

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..

Database Alert Rule Engine

Hello ,
I am running Oracle XE . This database collects information about server statistics in my organization ( memory usage, threads running, etc). Now , I need to send alert/ notification emails if the certain thresholds are crossed by server ( ex: if number of threads increase more than 100, send an alert email).
One way to do this is to write stored procedures and schedule them to run every hour and send alert email if conditions are met.
But what I want to do is to use some sort of rule engine where I can specify the rules/conditions which have to be true for alerts to be sent. The reason I want this approach is so that every time there is a new rule, I do not have to write a new stored procedure and I can just specify the condition in the rule engine .
So are there any Rule Engines out there that I can use?

Hi,
Yes.
Oracle has a monitoring tool built-in Entreprise Manager.
I suggest that you get started with:

Rule Engine Update service is not getting up

Rule Engine Update service is not getting up given below error(screenshot attached)
Error Details:
Windows could not start the Rule Engine Update Service service on local computer
Error 1053: The service did not respond to the start or control request in a timely fashion
I had installed CU7 and increase timeout time but no luck..after uninstalled OS patch "Security Update for Microsoft Windows", service (Rule engine update service) can start again. Our wintel team want this OS patch for security in BizTalk server.
Could you please suggest how we can have security patch with rule engine service up.
Regards
Suman

If that specific patch is causing a conflict with CU7 or Rules Engine Update Service, the best option would be to LOG a case with Microsoft and let them either fix it or provide a justification of why that specific Windows Patch is not a good idea (file
an exemption in case of later with the customer/security team).
Regards.

I never had version 11.5 installed but I had the create bookmarks option. I had version 11.0 installed and had the create bookmarks option.
I'm still having problems installing Crystal Reports XI R2. It makes it through the entire installation and then a screen pops up telling me that it can not find "CrystalReports.msi". It is looking for this file in a temp file. I use the browse button and point it to the proper file location but it still won't accept it. The only thing I can do is exit out of the installation. Am I doing something wrong? Do I have to do something special to upgrade Crystal Reports?
