How to implement message throttling in DB adapter for outbound message

Hi all,
In my current we need to insert huge amount of data in the Oracle database. But the database will provide us limited amount connection. As per our observation number of total incoming request will exceed the total number available connection. In this case we have to throttle the incoming message. I know message throttling can be done very easily using OSB. But in this project we are not using OSB. We are using BPEL Process Manager and Mediator. I tried to specify the number of thread in the outbound DB adapter but it seems there is no such property in oracle.tip.adapter.db.DBWriteInteractionSpec or oracle.tip.adapter.db.DBStoredProcedureInteractionSpec.
Can anybody inform me what is the possible solution. Thanks in advance.

Check http://docs.oracle.com/cd/E21764_01/core.1111/e10108/adapters.htm#BABDJIGB
Unfortunatly currently valves are not supported by JMS or Database Adapter – only for file and ftp. Maybe you could use it on the incomming side check http://technology.amis.nl/blog/13849/soa-suite-file-adapter-pre-and-post-processing-using-valves-and-pipelines
little off topic; would it be possible to use ODI? Seems more suitable for the job...

How to implement select operation on DB adapter?

Hi, I have a requirement in which I have to retrieve a metadata value from metadata table using a DB Adapter and accordingly make decision like which flow to take using a Routing Service. If financialSystem1 value is retrieved, follow path1 or if financialSystem2 is retrieved from DB, follow path2.
How do I do this? How do I pass the value returned by DB adapter to the next Routing Service and use this value in the filter expression?
Thanks,

Thanks Eric. I am really pleased by your quick responses to my other postings. We are working on a critical project and we have picked Oracle ESB to be the middle ware.
Coming to the problem:
After selecting for a perticular record, in the reply part, I placed a filter expression as
/inp1:CStripesReqsCollection/inp1:CStripesReqs/inp1:fundCode = '10'. But the message flow stops right there and doesnt flow any further.(By the way it is considering the namespace as inp1=http://xmlns.oracle.com/pcbpel/adapter/db/top/InterfaceTable)
However, if I remove the filter condition, the result flows to the next node(For now a file write operation). and when it writes out, I check the contents and the contents satisfy the filter expression that I wrote. It is just not recognizing the filter expression that I am writing.
Here is the XML that it wrote to output file.
<?xml version="1.0" ?><CStripesReqsCollection xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.oracle.com/pcbpel/adapter/db/top/DBSelect">
<CStripesReqs>
<reqIntfId>100023330353</reqIntfId>
<fundCode>10</fundCode>
</CStripesReqs>
</CStripesReqsCollection>
Do you see any obvious mistake here?
Thanks,

How to implement Message Sequencing other than mediator

Hi All,
I am looking for a solution to implement the message sequencing option for the below integration scenario between Order management module and projects module using SOA and AIA 11g.
1. The source system triggering requests is the Order management module(sometimes projects module) of Ebiz R12.
2. When an order is booked an event is raised and pushed to WF_Deferred_Q in Ebiz environment.
3. This messages are pushed to WF_BPEL_Q in SOA environment by the QAgent configured at the Ebiz end.
4. At SOA end , there is an AqAdapter configured in OSB(as a proxy service) will poll WF_BPEL_Q and pull the messages.
5. Based on the type of request messages are routed to different requestor ABCS services( AIA framework).
Scenarios possible are:
1.     Orders created newly and same are synched to projects module.
2.     Orders updated and same is updated in the projects module. (order header id is same for multiple update requests on the order )
Scenario 1: Two update requests for same order
1.     When an existing order which has got five line items and each line item has got 2 sub line items, is updated at the same time from different locations(let’s say from India and Japan) where in order from India is updating the quantity on one sub line item whose parent line item is (lets say A) and another request from japan is updating the unit sale price in another sub lie item line item whose parent is also line item A.
2.     Both the update requests which are raised will have the same order header ID and also the request from India is errored out while updating the projects module due to some reason which needs some manual intervention to update the data and resubmit the message.
3.     Now we want to stop the request from Japan until the request from India is not processed.
4.     Simultaneously we want to allow the orders which are independent.
Note: We are not looking to use “wait” option which will have an impact on the performance .
Please suggest your valuable inputs and expert thoughts in implementing the message sequencing with less impact in this situation.
Thanks in advance.

Shailesh

Can someone post expert views on the below issue?

Can any body help me to say thet "How to install Oracle Applications 11i(11.5.10.2) on Windows 2003 R2 X64 bit ' . Hi,
I believe, 11i installation on Windows 2003 X64 is not fully supported.
what is your os version:
if it is windows 2003 32 bit, then it is supported on X86-64 servers for both database and application tiers
If it is windows 2003 64 bit, then only datatabase tier is supported on x86-64 servers
Have a look at the following note

How to implement optemistic locking in pl/sql for oracle database

i have search the net to find example of how i can do the optimistic locking in pl/sql, all the resources i found were old , for example "Optimistic Locking with Concurrence in Oracle.
As " by Graham Thornton Snr. Database Architect / Oracle DBA in 2001, but at the end he said that the approach will not work fine if the update being made is a relative update, this apprach includes:-
1.add a timestamp column to an exsiting table.
2.add a preinsert trigger on the table to set the timestamp.
3.add a preupdate trigger to comapre the old time stamp with the new one.
So where i can find updated resources about this issue.
Edited by: 812643 on 17-Nov-2010 12:39

totally plagiarized from expert oracle database architecture 9i, 10g, 11g by Tom Kyte pg201
one popular implementation of optimistic locking is to keep the old and new values in the application and upon updating the data use and update like this
update table
set column1 =: new_column1, column2 = : new_column2, ...
where primary_key = :primary_key
and decode( column1, :old_column1, 1 ) = 1
and decode( column2, :old_column2, 1 ) = 1
another implementation
optimistic locking using a version column
add a single column to each database table you wish to protect from lost updates. this column is generally either a number or date/timestamp column
It is typically maintened via a row trigger on the table, which is responsible for incrementing the number column or updating the date/timestamp column
every time a row is modified.
another one on page 204
optimistic locking usin a checksum
similiar to the version column implementation but it uses the base data itself to compute a virtual version column.
the ones suggested where owa_opt_lock.checksum, dbms_obfuscation_toolkit.md5, dbms_crypto.hash, ora_hashEdited by: pollywog on Nov 17, 2010 3:48 PM
might be a good book for you to look into getting it has a whole chapter on locking and latching.

How to connett via hdmi and VGA adapter for my Toshibe 3LCD data projector

My HP Pavilion running windos 8.1 can not converse via HDMI A to VGA adapter to Toshibe TLP470Z data projector

Checking the manual for the Toshiba projector, found HERE, it states:
The projector cannot be connected to a computer that does not have
an analog RGB output terminal. For details, refer to the computer
manual.
• You may not be able to connect some computers to the projector.
The model number of your Pavilion PC would be most helpful.

How to implement index array inside case structure for searching a 3D array?

Well I have a 3D array and I want to index certain elements from that array. And I have thought of one way of doing this is to have multiple index array functions on the block diagram to search the array simultaneously, but that would be messy. Or I could setup some kind of case structure and place each index array function into individual cases. I've tried the latter, but when I connect the 3D array to the case structure at the"?" it doesn't give me permission because it says I'm hooking up two different types of data. Case Structure is for T or F and 3D array is not a boolean.
So how can I setup the Case Structure to work for a 3D array?

A case structure's selection tunnel cannot accept an array. What exactly are your search criteria? It sounds like a few FOR loops will be needed.

How to implement long-distance box-box Redundant for CSS product?

I want to config box-box redundancy for CSS,but It's about 1200+ meters from one to the other,
so it couldn't implement using crossover UTP cable.
(DOes it work well when link with Fiber optical transceiver between the two Content Switches ?)
or
Would you pls. give your solution for this ?
Thanks,
thomas

As far as my knowledge goes I think cross over cable is the only option.When the CSS are too far apart, Box-to-Box
redundancy cannot be used.A gige-cable cannot be used for failover.
Have a look at this:

How to Implement Abap Object and Access Key for se24 developers.

Hi every One,
This is Abdul Rahman, Started Learning Abap Objects i want a simple program to be executed i.e. in Local class (Abap program)and as well in global class(class builder).
Also i would like to know When ,Were and Why Abap Object should be used.
prob to Me :- When i wanted execute F8 a Class in se24 Class Builder it is asking me AcessKey , plz if this is required plz any one send Me.
I have this key 36687663221261278694 it is already used in Abap editor , it is not accepting in se24 .
plz help Me , waiting for response ..
thankyou so much
Abdul Rahman.

Hello Abdul
Here are my answers to your questions:
(1) Local classes: Do not use them.
- As long as your class is rather small (few attributes and methods), local classes are ok yet as soon as they become larger you will loose the overview
(2) Global classes: Do use them.
- Make use of global classes even if they are only used for your training. The big advantage over local classes is that you will get used to the classe builder (SE24) which has a plethora of functions.
(3) Executing global classes: Can be done if you have defined an OO-transaction.
- An OO-transaction has a class and one of its public methods as parameters (similar like report transactions). When you all the OO-transaction an instance of you class is created and the public method is called.
(4) Where and Why use ABAP Objects? Everywhere. Anytime.
- ABAP objects is about stability, maintainability and re-usability of coding. These developer aims can be much more fulfilled using ABAP OO means than in classical programming.
Regards
Uwe
PS: There are situations where local classes are quite appropriate and, using ABAP Unit testing, are obligatory.

How to connect to third party using PI for outbound and inbound interfaces

Hello,
I have scenarios where I have data coming in from third party EDI subsystem and sent to SAP. And also from SAP to EDI subsystem. We need to send the XMLs to the EDI subsystema nd also receive XMLs.
Can someone please suggest the ways I can connect to EDI subsytem for both Outbound and Inbound interfaces.
Thanks

Hi Prabhu,
EDI file is different from the normal flat or xml file. Hope you understand the difference.
Now if your EDI subsytem has the capability of converting the xml file to edi file viceversa then create and receive the xml file from the EDI subsystem. For the xml file you may use the file adapter as an option.
If it doesnot have the capability then seeburger adapter needs to be used. This is not an inbuilt adapter. So your company needs to purchase it.

For doing this, you have to enable the file multiselection.
