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.

What is ESB and OSB? why OSB when ESB avail? when to use which of these?

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. Below SOD should help you out in understanding -

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:

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 Coherence and OSB caching

Hi Guys,
I have a few queries regarding Oracle Coherence.
1. Is OSB business Service Caching internally uses Oracle Coherence.
2. If answer to above question is YES, then can I install Weblogic without Oracle Coherence.
3. Again if answer to above question is YES, will OSB caching work without Oracle Coherence and if yes, then How?
4. Can we create clustered weblogic domain without oracle coherence.
Regards

Thanks Durga/Abhinav,
The links clarify a lot.
Now what i need to know more is that when i installed Weblogic server (default configuration) and created a OSB server as managed server in wls domain. I could use the OSB caching in business services without any issue. However, there is no coherence server under "Coherence Server" in weblogic console. How the caching is working in OSB when i havn't configured any coherence server on weblogic?

What are the differences between ESB 10g and OSB 10g

Hi,
I'm newbie to OSB 10g. I have installed OSB 10g.
I came to know after Oracle acquired BEA, the ALSB is renamed as OSB.
I'm curious to know what are the differences between ESB and OSB.
If there are many differences, please post any links which provide the required information in detail.
Thanks in advance.
Regards,
Udaya

the 'old' esb has been renamed to mediator and is now only used as component in your sca application.
the two service buses can't really be compared since the osb (former alsb) has way more functionality in it.
Oracle gave it it's own place in his soa portfolio and the old esb can only be used als mediator in your sca application.
On top of your sca application you could use the OSB to complete your architecture design.
the difference between both.
esb (now used as mediator) can only be used in your sca application
in here you will use it mostly for routing/transformation, and there is some functionality for assign/java callouts conditional routing
the osb is complete product with a lot of functionality in it. Everything you used the old 'esb' for can be done in the OSB and with a lot of extra's.
routing/transformation/service call outs/java callouts/transport virtualization/security/and more and more
you should read the guides of the OSB to get an idea of everything it can do for you.

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

Exploring the transaction boundaries between ESB and BPEl

Hi
I was working on how to explore the transaction boundaries between the ESB and BPEL.
How to work on these I have some confusions over in this.
Please help me.
Cheers.

Jan,
Are you sure about this ?
http://www.oracle.com/technology/products/integration/esb/files/esb-transactions-errorhandling.pdf
I'm not a die-hard at the transaction-mechanisme so some wild guessings.
If i look at this document, i can define on every routing rule the sync/async processing.
If i select on both db-adapter-routings the sync-option, and i make sure both dbadapter-connections make use of the xA properties in the datasource-properties, shouldn't this help him on his way?
I haven't tested it, so im curious what it would do, or do i miss something?

How to download a file from Oracle UCM using OSB

Hi,
How can I download a file from Oracle UCM and save it on a filesystem using OSB 11.1.1.5.
Thanks

UCM supplies webservice interfaces which let you retrieve the filecontent by soap calls from UCM (http://ucmhost/_dav/cs/idcplg for example). (maybe you should enable some settings on ucm to have this webservice interface getting published).
This services for example has 2 operations getFileByID and getFileByName.
So you can just call these services from within OSB.
After that you need to do some tests if you eitherway need to create a file-transport business-service and call this one from your proxy service or create a messageType proxyservice (binary) which calls this file-transport business service to be able to write fo filesystem.
I think for the OSB book i used a jca file adapter generated in Jdeveloper and used that one to write to filesystem.
