Rule-based or 'expert' system in Oracle

Hi,
Has anyone implemented a rule-based system in Oracle? E.g. based upon a decision tree?
I have a feeling that the algorithm will involve 'tree-walking' within a heirarchy of rules but I'm not quite sure how to structure it. I have a couple of ideas such as storing pointers to the next rule with the columns holding things like the name of the parameter, the condition, the comparison value and the outcome.
The program has to choose a carrier (such as UPS or Fed-Ex) based upon rules such as the weight (<1kg?>, the intrinsic value (> #100), the addressee postcode and whether the package is hazardous or not. There can be any permutaion of these conditions apart from those that are direct opposites (such as greatr than or lower than 1kg).
I would be grateful for any advice on this, or a web address that might help (I have googled and found something calld the 'reme algorithm' but cannot find any elaboration of it! grrr.....).
Thanks for your time,
Regards,
Jim.

thanks for your reply, but need different thing,
suppose we prepare a report in report builder and when we want to print it, it always print in windows gui fonts like times new roman, arial , tahoma etc..
I WANT TO PRINT IT IN TEXT-BASED FONTS NOT WINDOWS FONT WHICH GAIN HIGH QUANTITY OF TONER . I want to print like IBM COBOL, FOXPRO, GWBASIC, PASCAL TEXT MODE REPORTS

Re: Oracle 8i (8.1.7.4) Rule based v/s Cost based

I think the answer you are looking for is that Rule Based optimizer is predictive, but Cost Based optimizer results may vary depending on statistics of rows, indexes, etc. But at the same time, you can typically get better speed for OLTP relational databases with CBO, assuming you have correct statistics, and correct optimizer settings set.

Partitioning on Oracle 8i (Rule Based vs. Cost Based)

At my current engagement, we are using Oracle Financials 11.0.3 on Oracle 8.0.6. The application uses rule-based optimizer. The client wants to implement Oracle partitioning. With this in mind, we are concerned about possible performance issues that the implementation of partitioning may cause since RBO does not recognize it.
We agree that the RBO will see a non-partitioned table the same as a partitioned. In this scenario where you gain the most is with backup/recoverability and general maintenance of the partitioned table.
Nevertheless, we have a few questions:
When implementing partitions, will the optimizer choose to go with Cost base vs. Rule base for these partitioned tables?
Is it possible that the optimizer might get confused with this?
Could it degrade performance at the SQL level?
If this change from RBO to CBO does occur, the application could potential perform poorly because of the way it has been written.
Please provide any feedback.
Thanks in advance.

If the CBO is invoked when accessing these tables, you may run into problems.
- You'll have to analyze your tables & ensure that the statistics are kept up to date.
- It's possible that any SQL statements which invoke the CBO rather than the RBO will have different performance characteristics. The SYSTEM data dictionary tables, for example, must use the RBO or their performance suffers dramatically. Most of the time, the CBO beats the RBO, but applications which have been heavily tuned with the RBO may have problems with the CBO.
- Check your init.ora to see what optimizer mode you're in. If you're set to CHOOSE, the CBO will be invoked whenever statistics are available on the table(s) involved. If you choose RULE, you'll only invoke the CBO when the RBO encounters situations it doesn't have rules for.

Rule based system in SQL

we have an airline pricing system whose rules change often, and rather than re-designing tables and the client application code everytime that happens, we would like to develop a rule-based system to dynamically store the rules in a rule-based system that doesn't require re-design and code modification.
any ideas ?
here is an example of the data that we would like to store
if seasonality is LOW
and passenger is CHILD
and carrier is TRW
and origination is COS
and destination is PIT
and ticket code is Y
then price is 908
seasonality for carrier TRW is LOWfor travel between 01/15/06 to 04/15/06
seasonality for carrier JAR is LOW for travel between 02/01/06 to 05/01/06
age for carrier TRW is CHILD for passenger age betwen 2 and 12
age for carrier JAR is CHILD for passenger age between 6 and 14
.. and another price can be given with an entirely different set of rules
reason is ask in this forum is I read a blog of someone who praises the set-based nature of the SQL language for developing exactly this kind of system, rather than trying to implement it on the client (for example using JRules)

What version of Oracle are you on? 10g introduced a rules engine into the database (Oracle Rules Manager and/or Oracle Expression Filter) which would seem to be right up your alley.

Rule based monitors (RZ20) - Show system availability for selected systems

Hi experts,
I'm new with CCMS monitoring and need an advice for rule based monitors.
I want to create three alert monitors (RZ20). One for our developing systems, one for our quality assurance systems and one to monitor our production systems.
For the start, I want to show data in each of this monitor for free space of the filesytems (MTE class: "FilesystemFreeSpace"), for users which are locked out (MTE class "R3SyslogSecurity") and for the availabilty of the ABAP systems (MTE class "Availability_SysPercent_ABAP").
I started to create the monitor for our developing system and got a problem. I started with the rule "CCMS_DEFINE_R3_SYSTEMS" to select our developing systems "HRT", "CRT" and so on. Under this nodes, I defined the mte classes ("CCMS_GET_MTE_BY_CLASS") which needs to be shown: "FilesystemFreeSpace", "R3SyslogSecurity" and "Availability_SysPercent_ABAP".
When I checked the results, I was able to see the free space of the filesystems and whether a user has been locked out. Unfortunately, I recognized that the availability is not shown. Instead there is the message "No MTEs currently available".
I'm aware, the availability cannot be shown on this way, since the agents are part of the central monitoring system and hence i need to choose the central system for "CCMS_DEFINE_R3_SYSTEMS". However I'd like to show the availability separated for each system under "HRT", "CRT" and so on. That means for example, there should me a node "HRT", which contains the free space of the filesystems, whether users are locked out, and the availability for the system.
It's not a problem to get a solution with a static monitor. I simply create a virtual node "HRT" and tick the checkbox under "<central system>, ..., <availability>, <hrt> ..."
However, I'd like to use rule based monitor to keep the effort at a minimum by not ticking thousand of check-boxes when I expand the monitored objects.
I also tried to use the rule "CCMS_GET_AVAILABILITY_FOR_SYSTEM", but it doesn't work and SAP documentations say "This rule is reserved by SAP for later use".
Does anybody know a solution for my problem?
In addition, I've got one more question concerning rule based monitors: If I want to create a monitor for my developing systems, I'll not be able to choose "<all>" for "CCMS_DEFINE_R3_SYSTEMS". Do I need to create "CCMS_DEFINE_R3_SYSTEMS" for each system separately? Or is there another possible way?
Thanks for your help in advance.

I read something about logical MTE classes: http://help.sap.com/saphelp_nw04s/helpdata/en/31/5462405c910272e10000000a155106/frameset.htm --> Does I need to use this?

Sorry Sean for my very late anwser.
I was very busy in my company.
Yes, I had tried you suggestion but it didn't work for me.
The problem is, that the Agent "CCMSPING" is part of the central monitoring system by definition.
Furthermore I tried to copy the default availabiliy monitor to look how it is definied. It didn't help.
I made the decision to define my monitor differently (an extra monitor for the availability for all system) and replace this temporalily solution when ""CCMS_GET_AVAILABILITY_FOR_SYSTEM" will be available.
The situation is not so bad after all.
Thx for your help. I appreciate it!!

Oracle 9i - rule based settings

How can change the cost based setting to rule based in oracle 9i? Could anybody help me?

ALTER SYSTEM SET OPTIMIZER_MODE=RULE SCOPE=BOTH;
Won't work, you'll have to change your parameter file and then restart the DB to change optimizer mode at instance level.
For a session you can change it using the command
ALTER SESSION SET OPTIMIZER_MODE=RULE;

Connect SharePoint to SQL Server Database Then Build Rules Based Returns System

Hello Guys,
I work for an ecommerce business. We sell a wide range of products to customers all around the world which are ordered from our websites and then dispatched to our customers from our warehouses.
I have been tasked with developing a computerised return system from the company because at the moment everything is done using paper forms.
We have all our customer, order and product data within SQL Server databases.
What I would like to know is...
1. Can we connect sharepoint online to a local sql server database
2. Could we then build searches within sharepoint to display data contained within these databases e.g. customer information etc
3. How is the data presented in sharepoint - is there a way to design how the data is displayed within sharepoint etc?
4. Can we then build a rules based return system within sharepoint? The on screen workflow would need to vary according to data contained within the database e.g. the weight if the product being returned and also on fields input by the service agent such
as the reason for the return, what solution the customer would like etc.
5. is it possible to build these workflows in such a way that they can be saved part way through then gone back to later
6. Can reports be build based on the returns that are being generated e.g. list of products most commonly returned
Sorry for all the questions, I am a bit of sharepoint novice. I think it may possible be able to do what we need but I just wondered if the answer to any of the above questions is definately a no because if it is that could mean it is not suitable
Thanks

You could use a BCS connection
http://community.office365.com/en-us/b/office_365_community_blog/archive/2012/10/11/business-data-connectivity-services-in-office-365-sharepoint-online.aspx, this will allow you to edit data in your non SharePoint SQL DB, on premises, from Office 365 SharePoint.
Search will index the web applications you point it at, and the lists from the BCS will be part of those web apps, site collections, sites at some place and will get indexed.
You can create views on the data, that can sort of work like a search, but when you search on the site where the lists are the query will return results based on the BCS data.
These views can be based on criteria such as the weight of the product being returned and other fields.
The data is presented as a list.
You can make it read only or read-write based on SharePoint permissions on the list. The account used to create the connection can edit.
BCS is possible in on-premises SharePoint too
here is a good read on it,

Rule Based System

Hi all,
I am currently working on a project which required to Implemented 500-600 rules in the System. Some of them are global Rules and some are just module level rules.
Is there any pattern exist for Rule Based System?
Thanks in Advance
Rashmikant

Just 1 pattern?
The short answer: No.
The longer (though still short answer):
A rules engine is not the easiest thing to implement, just 2 or 3 classes don't hack it if you're working with a dynamic rule base that is steered based on input/ouput and states.
There are rules engines for sale and there also a few opensource, look on the internet, use your best best friend.

Installation of latest (oracle based) Process Integration system

Hello
I wander where to find latest instruction guide for installation of latest (oracle based) Process Integration system.
I is a little confusing to me. I sit not a part of NW7.4? In SWPM there is a complete dedicated section to PI 7.1.
I have under SWPM two packages and I do not know chich is corrrect:
70SWPM10SP04 and SWPM10SP04
Thhank you for your help
Jan

Hi Jan - Yes. For 7.4(even for 7.3)we should refer to the installation documents under the relevant product version. There is no separate category like 7.1 and 7.1 EHP
what is the operating system? Are you looking for dual stack or single stack installation?
However have a look at the below master guide..

Questions on Rules-Based ATP and Purchase Requisitions for STOs

Hello experts,
We are working on rules-based ATP configuration and have several questions about the functionality. Iu2019m hoping that some of you are using this functionality and can help give us direction.
In our environment we have multiple distribution centers and multiple manufacturing plants. We want to confirm sales orders against stock and production orders in any of those plants, depending on the locations that have stock or planned production. For example, we will place a sales order against plant A. If there is not enough stock in plant A then rules-based ATP will use location determination to check in plant B, then C. The scope of check on the ATP check will include stock and released production orders. We will configure plant A as the u201Cconsolidation locationu201D so if stock is found in plants B or C then stock transport orders will automatically be created to move the stock to plant A before shipping to the customer.
We have configured rules-based ATP and this functionality is working well in our Development system. The ATP check is executed and uses the rules-based ATP to find eligible stock in other plants. The system is also creating purchase requisitions to move the stock to the consolidation plant.
Our first concern is that there doesnu2019t appear to be any firm linkage between the sales order and the resulting purchase requisition. For example, if we create sales order 123 for plant A and the rules-based ATP finds stock in plant B it automatically creates a purchase requisition 987 to move the stock from plant B to plant A. However, there doesnu2019t appear to be a linkage between sales order 123 and purchase requisition 987. For instance, if we delete sales order 123 the purchase requisition doesnu2019t get deleted.
Our second concern is that the quantity on the purchase requisition can still be confirmed against later sales orders. For example, say the above scenario resulted in a purchase requisition 987 that consumed all the stock available in plant B. We then create a second sales order 456 for the same product. Plant A is out of stock so the rules-based ATP looks in plant B. We would expect that plant B would also not have any stock because itu2019s all been consumed by the purchase requisition. Instead, the system creates a second purchase requisition to move quantity from plant B to plant A. Itu2019s as if the system doesnu2019t realize that the purchase requisition 987 is already planning to move stock out of plant B.
Does anyone have any thoughts or suggestions on these two scenarios? Is there a way to configure the system so there is a hard linkage between the sales order and the purchase requisition so that if the sales order is deleted then the purchase requisition is also deleted? Should ATP realize that purchase orders are consuming inventory and not allow later sales orders to confirm against that same inventory? Any advice or experience would be greatly appreciated.
Thanks,

Hi,
The scheduling is done in SCM, and from there, whenever the RBA is triggered, the calculation is done always with the old route in SCM. Until you get back to R/3 this is when your route is determined. But the ATP check is always with the original route. So the idea would be that you change the values of the route while still in APO, this is possible via the user exit. Should be done in scheduling in APO.
Hope this information is helpful.

Improving performace for a Rule Based Optimizer DB

Hi,
I am looking for information on improving the current performance of an ancient 35GB Oracle 7.3.4 using RULE based optimizer mode. It is using 160 MB SGA and the physical memory on the system is 512MB RAM.
As of now, all the major tasks which take time, are run after peak hours so that the 130 user sessions are not affected significantly.
But recently am told some procedures take too long to execute ( procedure has to do with truncating tables and re-populating data into it ) and I do see 54% of the pie chart for WAITS are for "sequential reads" followed by "scattered reads" of 36%. There are a couple of large tables of around 4GB in this DB.
Autotrace doesn't help me much in terms of getting an explain plan of slow queries since COST option doesnt show up and am trying to find ways of improving the performance of DB in general.
Apart from the "redo log space requests" which I run into frequently (which btw is something I am trying to resolve ..thanks to some of you) I dont see much info on exactly how to proceed.
Is there any info that I can look towards in terms of improving performance on this rule based optimizer DB ? Or is identifying the top sql's in terms of buffer gets the only way to tune ?
Thank you for any suggestions provided.

Thanks Hemant.

Rule Based ATP- Error in calling up function 'BAPI_APOATP_CHECK' in APO ser

Hi Experts
I hae configured Rule Based ATP with Multi-Level ATP check. I have completed all configuration required for Rule Based ATP but still facing an error
" Error in calling up function 'BAPI_APOATP_CHECK' in APO server 'SC5CLNT001': Check instructions 30 / A does not exist for locat"
Have any of you ever encountered this error?
Regards,
Sushovan Datta

Dear Sushovan,
Most likely cause of the above error is a missing requirement class in R/3 and missing Check mode in APO for material and plant combination.
Please read the F1-Help for field check mode in APO:
"Together with the business event, the check mode derived from the product master defines the type and scope of the checks carried out. It also controls forecast consumption.
SD (R/3) uses the requirement class of the requirement as check mode. As of R/3 Plugin 2000.1, the requirement class is transferred (via the strategy group in the material master) to the location-specific APO product master (ATP tab page). In the process, no plausibility check is carried out. For this reason, you should not enter any other check mode in the product master. (The check mode in the product master must agree with the requirement class from the R/3 system.)"
So please create for your material in corresponding plant the requirement class ' 030' assigned to the strategy group in MRP3 in R/3 and the same in the check mode field in //mat1 in APO.
Afterwards the gatp check will find the check mode and business event (check instructions) and the error will be not appear again.

Tibor

Implementing roles and rules based authorisation with Azure AD

Hi all,
I would greatly appreciate some input on feasibility and patterns I should look at for a complex technical requirement that I am currently tasked with designing.
We have a system that comprises a web and mobile app. In the past we have implemented session based authentication through ADAM and authorisation through custom business rules contained within the applications. The authentication mechanism is in the process
of being migrated to Azure AD and authorisation is planned to be moved to Azure AD for our next release.
Existing authorisation within our web application is already complex. We have users that belong to different groups with a range of permissions such as read, write or admin. Additionally each user is granted access to N customers and also N locations within
each customer. We have a requirement that any number of combinations of customers and locations be supported. Users also need to have different permissions for each entity, i.e. read access to customer 1 location 2, write access to customer 4 and administer
customer 7. Currently these privileges are maintained within a relational database and enforced as part of each PageLoad(). Essentially this is a combination of roles and rules based authorisation.
We are struggling to represent this complex matrix structure within Azure AD and efficiently implement the authorisation decision in Azure AD. The driver for this technical requirement is to provide re-usability of the authorisation component to other (as
yet unidentified) applications.
Currently the best option we have come up with is implementing custom attributes for each class of permissions and storing within this 2048 bit field a bitmask that represents whether this permission is granted for a given location (which has a many to one
relationship with customer).
Any help or comment would be gratefully received,
Phil

Hi
When "Advance routing" is used for Task assignment; the task service asserts the folllowing fact types : Task, PreviousOutcome and TaskAction to the rules engine. These facts gives all the reqd info about the task (like outcome of the participant, task stage .. etc)
Now in the defined ruleset; we can have rules as per our requirement that can extract info from the asserted fact types and assign task to the required/next participant.
Also note that we write the advance rules for exception cases only.
For example; let's say all participants have 2 possible Outcomes [COMPLETE, RECHECK]. We have defined the ideal task routing flow as :
Participant A -> Participant B -> Participant C. This is the flow when all participant selects "COMPLETE"
Now suppose B selects outcome as "RECHECK" then the task shld move back to A. So for this case only we need to write a advance rule.
Pls refer to the code sample at : http://download.oracle.com/technology/sample_code/hwf/workflow-106-IterativeDesign.zip
Also dev guide : refer to section 28.3.7.2 http://download.oracle.com/docs/cd/E14571_01/integration.1111/e10224/bp_hwfmodel.htm#BABBFEJJ

Rules based ATP not working

Hi Experts,
We are facing couple of issues with Rules based ATP . The scenario is we are using only location based substitution
1) We are creating an order for a material in ECC . This material is GATP relevant & the settings are made for rules based ( if no stock available at Plant 1 it would check for stock at plant 2 and confirm the requested quantity if available ) , ATP check is happening after creation of order for plant1 , but it is not checking for quantity at plant 2 eventhough quantity is available at Plant 2 .
I am checking the rules, it says no rule was found ,it is not possible to dispaly the rules , But for the sameif i am doing a ATP simulation in APO , it is working fine , the susbstitutions are happening & confirmations are being done.
2) IS it possible to use both checking horizon & rules based ATP ? The situation is if we use Checking horizon in check control , any SO will get confirmed based on checking horizon , if no receipts or stock is available before the CH . If the rules based ATP is present along with CH for plants 1 & 2, the system is still confirming the quantity at the CH on Plant1 , even though there is enough quantity to be confirmed at Plant 2.
Thanks for your help
Regards
Surendra

The first issue is solved . There was discrepancy in the data format between APO & ECC . The data when transferred to APO from ECC has been converted to a format which APO uses & when a SO is created in ECC the data that was entered in the SO is not being recognised by APO so the error .

Surendra

Rule based GATP Check

Hello experts,
Our team has configured rule based gatp check parameters and maintained condition technique, relevant rules with product substitution, location substitution, profile parameters and rule determination.
We are having four condition tables i.e. most specific to most generic and condition records are maintained for all the key combinations, whereas system is picking up the record, which is most generic.
Please let me know how the system picks up the condition record in rule based atp check.
Thanks and Regards,

Hi Anupam,
Please find the comments.
Can you also check your check instruction and see if it has
--> "Activate RBA" and "Start immediately" check box checked for the check mode you guys are using and business event A
Comment:
Both the check boxes are checked for the relevant combination.
If you have this setting then I would like you to check in master data where you have created Integrated Rules:
Comment:
I've maintained only one rule, which is in valid periods.
Make sure you have maintained integrated rules correctly and assigned the correct location determination procedure.
Comment:
Checked both Production Substitution and Location determination procedures and their assignments.
--> Very basic point but no harm in checking, sometimes we miss very basic things: Do you have all the locations in APO and also products at those location which you want to populate in the sales order.
Comments:
All the combinations of products and locations are in APO.
Thanks,
Sai Dacha
