Oracle ESB and Mediator

Hi,
I am evaluating many ESB products and Oracle is one of them, I have installed fusion middleware 11g and managed to configure it along with Jdeveloper requirements, but the bad news were that 11g does not support Oracle ESB yet and it supports the “Mediator” which is light version of ESB, could anyone please comment on this, is that’s right and is it ok to use Mediator instead on Oracle ESB, knowing that we need a robust heavy transactional ESB with many adapters to be supported.
Thanks,

Oracle ESB’s primary mission was
to provide service mediation and application integration capabilities to SOA
composite application developers. This use-case can be described as “in-line
mediation” since it is used for transformation, routing and event delivery inside of
what is logically a composite application.
Oracle Service Bus on the other
hand focused on solving the operations and scalability problems in a standalone
service bus. Here the use-cases that it focused on were those of service
virtualization, on-ramping and aggregation of external services and gateway
functionality.
By combining the respective strengths of Oracle ESB and AquaLogic Service Bus(Now OSB)
in the Oracle SOA Suite platform, Oracle will enable all the common ESB usecases
and provide unmatched flexibility and functional capabilities.
The Mediator(OESB/ESB) is an intra-composite mediation component that is
deployed within an application. It is responsible for brokering
communications between components that make up a composite, enabling
transformation, routing, event delivery and payload validation inside the
composite. The main users of the Mediator are application developers
assembling multiple components into a composite application which can
be deployed, versioned and managed as a single deployment unit (all based
on the SCA, or Service Component Architecture, standard). This is the
component that all the Oracle Fusion Applications are leveraging, as well
as AIA – the Oracle Application Integration Architecture. Oracle ESB
seamlessly evolves into the Mediator in the 11gR1 release.
The Oracle Service Bus provides standalone service bus capabilities,
enabling separation of concerns between application developers and target
systems or services. The main users of the Oracle Service Bus are
integration developers and operations personnel. Their mission is to shield
application developers from changes in the endpoint services or systems
and to prevent those systems from being overloaded with requests from
upstream applications. In the 10g and 11g releases, the Oracle Service Bus
will also be augmented with key features from the current Oracle ESB,
such as domain-value-map, cross-references, JCA adapters and a
JDeveloper-based design-time. The Oracle Service Bus is based on
Aqualogic Service Bus, with the incorporation of some of the advanced
features from the Oracle SOA platform.

Oracle ESB and OSB confusion

Hi All,
I am using SOA suite 11g. I have confusion with Oracle Enterprise Service Bus and Oracle Service Bus
1> Is ESB and OSB same ? If not, then from where do i download Oracle ESB ? and what would it do different from OSB (*I already downloaded OSB and was able to deploy and run one of SOA application. Also, I have SOA server instance running on my weblogic server as well.* If I have OSB, is it necessary to download Oracle ESB as well ?
2> I have seen couple of job requirements that just mentions--- ESB experience required Do they mean Oracle Enterprise Service Bus experience ?
3> SOA/Bpel application developed using Jdeveloper 11.1.1.2 can be deployed to any third party service bus (including IBM and Mule) ? OR it will only run in Oracle service bus. ? This question is just like for example --- developing standard JSR 168 portlet that you can deploy on any third party portal server.
thanks,
pp

If you are using 11g SOA Suite there is no, Oracle Enterprise Service Bus, it has now been renamed as Mediator. Mediator is now part of the composite.
To answer your questions.
1. No they are not the same but they can perform similar functions. Oracle ESB is 10g and is part of the 10g 10.1.3.1 install which is found on OTN, not sure you can get the standalone version without raising a SR you may find it on eDelivery.oracle.com. If you have OSB installed there is no requirement to have Oracle ESB as OSB will perform everything Oracle ESB does, (apart from domain values maps, but this can be done in BPEL)
2. ESB is a generic term and does not mean it is Oracle, as there are many ESB out there. I would say OSB if it is an Oracle job, but you may need to know both. If you know mediator you will know Oracle ESB so you don't need to download.
3. You don't deploy SOA/BPEL into a service bus. They are deployed to and application server where SOA Suite is deployed. At this time SOA Suite is only certified with Oracle Web Logic but other app servers will be coming. Having said that your SOA/BPEL application can consume services on other application servers as long as the WSDL and endpoint are accessible from the your SOA Suite machine. They will be treated as web services. The JSR168 standard means that if your portal solution is JSR168 compliant then you can consume JSR168 portlets, these portlets can be deployed on any 3rd party app server.

PS Oracle owns Mule as well.

OSB or Oracle ESB????

Hi all..
We know that oracle has two service bus's OSB and Oracle ESB....i heard in future releases of SOA Suite OSB gonna replace Oracle ESB..and
Oracle ESB will behave something as mediator...Can someone explan wats the oracle statergy regarding these two products in future...also
wch is best OSB or Oracle ESB...can someone throw light on this.

Have anyone used rejectedMessageHandlers for Oracle ESB 10.1.3.1---urgent

Hi,
I am using rejectedMessageHandlers property for Oracle ESB(10.1.3.1).
I am reading data from a file and writing out the data into another file.I need to implement the following scenario:-
If it enconters some error in the structure of the file or encountered any error while reading the source file then it will generate a file dumping the error message and the payload.
For this I have used an endpoing property in "DefaultSystem_Read_RejectionHandler.esbsvc" (the esbsvc file for the File Adapter service for source file).
*<endpointProperties>*
*<property name="rejectedMessageHandlers" value="file://C:/jdevstudio10133/jdev/mywork/RejectionHandler/ESBRejectionHandler/reject"/>*
*</endpointProperties>*
But the file that is getting generated is "INVALID_MSG_null_Read_20081229_064024_0117.dat" with no data in it.
Can I use the property rejectedMessageHandlers for version 10.1.3.1 for Oracle ESB?Did anyone tried it out?
Can anyone also guide me with links or docs regarding usage of RejectedMessageHandler for Oracle ESB and Oracle BPEL.
thanks

Thanks Marc.
I was not able to find the patch on metalink. Could you please give me the patch number specific to only ESB 10.1.3.4 if you have.
I have the 10.1.3.4 patch number(7272722) for the complete SOA suite.
Also please comment on adapters part.

Periodic Dips in Performance for Oracle ESB

Hi,
We have recently been load-testing Oracle ESB, and used the following two flavors for our tests:
SOA Suite with Oracle Lite as the backend DB
SOA Suite with Oracle 10g as the backend DB
We have noticed that there are periodic dips in the performance for both flavors of SOA Suite, and were wondering if any of you had any ideas as to why this might be the case.
A graph that illustrates the issue can be found here:
http://www.ushareit.com/view.php/6b9fff3277dcb87ff5c86fca4ed0d762.html
The "Oracle" line pertains to SOA Suite with Oracle Lite, while "Oracle2" pertains to SOA Suite with Oracle 10g.
Thanks

I suggest to run the SOA Suite with Java Garbage Collection on, to verify if those dips can be related to Full-Garbage-Collection. If so you should tune the GC, via setting the heap size parameters of your JVM.

Can't I invoque an EJB in the Oracle ESB??

Hi all,
I'm just new on Oracle ESB and may be in error, but I have readed that RMI transport is not suported... Is it really true??
What can I do if I want to expose an EJB as a Web Service in the Oracle ESB??
Regards David

I am doing the above quite successfully in a number of ESB processes.
My EJB's are exposed a EJB3 session beans with a web service interface and as mentioned, can be called via a SOAP service.

How to integrate GRC10.1 and Oracle ESB(Enterprise Service Bus)

Dear，
we are delivering an GRC Access Control project.
Now, we need to integrate GRC10.1 and Oracle ESB, how should we do? Who could help show me some guide, thanks a lot.

deepak - why not link to the real documentation instead of that site that illegally publishes stuff?
Krasimir - I had a look at this a long way back, and didn't explore it much further because I reached a dead end in trying to figure out how it worked. It seems to me that the function is there and may be used internally within Oracle, but that it's not documented well enough for we mere mortals of the public to use it.
Have you tried opening an SR with Support? They won't know, but they will be able to raise it up and perhaps find someone who does know - be sure to reference this thread in your SR if you go that route.

Integration with Oracle ESB 10.1.3.1 and Peoplesoft HRMS

We are integrating Oracle ESB with Peoplesoft HRMS using a SOAP service to invoke a Peoplesoft HRMS webservice.
We are facing problems as HRMS application expects parameters - 'To' and 'From' with specific values to be passed in http header in the message from ESB as they are using http listener at their end.
We have tried to configure these parameters as end point properties in the SOAP adaptor but have failed to invoke the webservice at HRMS. They have given us a WSDL file and we have configured the SOAP adaptor with the same.
We get the following error -
An unhandled exception has been thrown in the ESB system. The exception reported is: "org.collaxa.thirdparty.apache.wsif.WSIFException: exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message transmission failure, response code: 500 at com.collaxa.cube.ws.wsif.providers.oc4j.jaxrpc.WSIFOperation_JaxRpc.invokeOperation(WSIFOperation_JaxRpc.java:1731) at com.collaxa.cube.ws.wsif.providers.oc4j.jaxrpc.WSIFOperation_JaxRpc.invokeRequestResponseOperation(WSIFOperation_JaxRpc.java:1473) at com.collaxa.cube.ws.wsif.providers.oc4j.jaxrpc.WSIFOperation_JaxRpc.executeInputOnlyOperation(WSIFOperation_JaxRpc.java:1156) at oracle.tip.esb.server.common.wsif.WSIFInvoker.executeOperation(WSIFInvoker.java:865) at oracle.tip.esb.server.common.wsif.WSIFInvoker.nextService(WSIFInvoker.java:781) at oracle.tip.esb.server.common.wsif.WSIFInvoker.nextService(WSIFInvoker.java:801) at oracle.tip.esb.server.service.impl.outadapter.OutboundAdapterService.nextService(OutboundAdapterService.java:208) at oracle.tip.esb.server.service.impl.outadapter.OutboundAdapterService.processBusinessEvent(OutboundAdapterService.java:127) at oracle.tip.esb.server.dispatch.InitialEventDispatcher.dispatchNonRoutingService(InitialEventDispatcher.java:118) at oracle.tip.esb.server.dispatch.InitialEventDispatcher.dispatch(InitialEventDispatcher.java:95) at oracle.tip.esb.server.dispatch.BusinessEvent.raise(BusinessEvent.java:1444) at oracle.tip.esb.utils.EventUtils.raiseBusinessEvent(EventUtils.java:112) at oracle.tip.esb.server.service.EsbRouterSubscription.onBusinessEvent(EsbRouterSubscription.java:305) at oracle.tip.esb.server.dispatch.EventDispatcher.executeSubscription(EventDispatcher.java:138) at oracle.tip.esb.server.dispatch.DeferredEventDispatcher.processSubscriptions(DeferredEventDispatcher.java:153) at oracle.tip.esb.server.dispatch.EventDispatcher.dispatchRoutingService(EventDispatcher

SOA suit 11g uses both ESB and OSB(ALSB)

Hi, I am newbie to SOA suit 11g. Can somebody please explain the use of ESB and OSB(ALSB) both in SOA 11g.In SOA 11g ESB is being used only for mediation.Even OSB(ALSB) has same capability.Then why both needs to be used?Can't we use one of these?
~Pradeep

hello Pradeep,
there is quite some literature on this hot topic - actually it's one of the most frequently asked question from people who are using OSB and Soa Suite.
if you google "OSB vs Mediator" you will find some useful links:

Can we Invoke the 'N' no.of webservices at the same time in Oracle ESB

Hi,
Good Day..
This is Ishmayel.Vemuri..
I little bit knowledge in ESB development..but having 3+ exp on webservices and java related technologies
I have the following requirment...
I have 'N' deparmental servers available in 'N' diffrent locations. We want move the data available in diffrent departmental servers(Oracle DB) into one centralized server..for this we developed one web services for each deparmental server to move the data.
** Now my doubt is Is it possible to call 'N' no.of webservices of 'N' departmental Servers in Oracle ESB by using any adpater service..? **
If you have any Idea kindly send me the details to [email protected]
Thanks in Advance..
Regards,
Ishmayel.V

Hi Ishmayel, sorry for my misunderstanding. But the situation you describe is also possible. Just add for each external reference a exposed service interface and wire this to a mediator component. Within this mediator you define only one operation that routes all the requests to one target server.
EDN is described over here: http://download.oracle.com/docs/cd/E12839_01/integration.1111/e10224/obe_intro.htm#SOASE004

Time Delay when Initiating BPEL from Oracle ESB

Hi there,
I am currently working with a client who have an on-going integration project. They are using the BPEL and Oracle ESB components of the Oracle SOA Suite 10.1.3.3.1. There is an issue that periodically occurs.
The scenario that we are occasionally getting is as follows:
The ESB is used to Poll for business events in a SQL Server database. Business Events are just information that needs to trigger a process occuring. The ESB has a DB Adapter that POLLS for these events. The ESB simply listens for these events, when one occurs it transforms the incoming message and invokes a Synchonous BPEL process that processes the message. Periodically in their environment, when the ESB DB Poller picks up a message, there seems to be a significant time frame between picking up the message and invoking BPEL. This has been anything upto 90 minutes. For Example messgae picked up 1t 12.30pm and the BPEL instance starts at 2.00pm. This issue seems to be uncreatable. Has anyone experienced similar issues or has any advice regarding this?
Any assistance / advise would be appreciated
Dave

Hi Ruplim
Thanks for quick response,
I want to Invoke ESB service from BPEL and get the Response Back in the form of Transformation Data.
I tried searching for Demo example in tutorials but i am not able to find such case, Do you have any documentation or Sample code for this type?
Thanks & regards

Best practice for version control B2B, ESB and BPEL

Hello,
we are setting up a new system using B2B, ESB and BPEL. The development team is more experienced working with PL/SQL, Oracle Workflow and we are worried that Jdeveloper generates changes to the source files during development and that we might have problems with the version control.
Is there any best practice for setting up version control for these systems? Do we need to take anything in particular into consideration when setting up the projects?
We are using Serena Dimensions 9.1 for version control with the add-on in Jdeveloper.
Thanks in advance!

I believe JDeveloper has a plugin for Dimensions.
I havent used it but to get it, go to tools (It may be help I don't have JDeveloper on this machine to confirm) check for updates.
If you select the thrid party check box - next, you will see an entry for dimentions.
Configure the connection and develop as you would any other project.

I need some simple examples to start with for Oracle ESB

Hi All,
Please share some simple examples to startwith for Oracle ESB.
I need to understand, what are the files are created, once created an ESB project.
What is the use of the files how to edit them with out using JDeveloper.
Iam trying to create a simple example.
I would like to create a file which has only "HELLO" in that file, simple text file inside a folder "INPUT" in my c:\ drive.
I wanted to create a ESB service which picks up the file and add a string to it like "HELLO" + "ESB" and drop this file into "OUTPUT" folder in c:\ drive.
How do i do that. I tried to do it when i deploy the integration server connection is gettting hit badly. I dont see that connection any more and i dont see that connection in my JDeveloper.
I dont want to start with existing code.
Please help

Hi,
If you want to do it from scratch you can basically do the following:
Make sure you have created an application server and integration server connection in JDeveloper.
1) Create a new JDeveloper project of type ESB project.
2) Possibly add a ESB System/Group (open the esb file and click "Create System/Group") to group ESB projects.
3) Create an XML schema describing your input XML file. Probably one element of type xsd:string.
4) Create an example XML file which is well-formed and valid according to the XSD from step 3.
5) Create a new File adapter (inbound/read). A routing service is automatically created.
6) Create a new File adapter (outbound/write).
7) Create a routing rule in the routing service in which you invoke the write method of the outbound file adapter. Possibly add a transformation using the XSL mapper.
8) Deploy the ESB project to the server.
9) Drop your XML file (from step 4) in the directory in which the inbound file adapter is polling.
10) If it is ok, the file should be picked up, transformed and dropped in the outbound directory. A new ESB instance should be visible in the ESB console.
See what files are generated on the filesystem in each of the above steps.

How to deploy a POJO or a java application in oracle ESB?

hi,
I m beginner in oracle ESB.
please someone tell me how to deploy a POJO or a java application in oracle ESB?
thank you.
Peter.

The short answer is "you wouldn't"
The long answer is that you would expose your Java Application or POJO as a Web Service then virtualise it through the ESB.

Hi,
What is ESB and OSB? why OSB when ESB avail? when to use which of these? Which is recommendabale?

ESB (Enterprise Serice Bus) is backbone of SOA. OSB (Oracle Service Bus) is an ESB product. Before the acquisition of BEA, Oracle was using OESB (Oracle Enterprise Service Bus) as a service bus but after that Oracle renamed ALSB (Aqualogic Service Bus) to OSB.
