SAP XI versus Sonic's Enterprise Service Bus

Hi,
Question 1:
In David Chappell's book 'Enterprise Service Bus', the Sonic ESB is described. He says that the ESB is more than a hub-and-spoke integration broker: ESB is a MOM and above that several 'generic' services, which handle the traffic and routing on the bus, for instance:
- Transformation service
- Content based routing service
- Orchestration service
- Splitter service
- Etc.
Is this concept adopted in ESA? If so how is this functionality implemented?
Question 2a: does XI uses xCBL as a XML-dialect?
Question 2b: does XI make use of the canonical-XML concept (by using xCBL) ?
Thanks in advance!
Greetings Theo

As answer on question 1:
No I never found any documentation from SAP that described a ESB solution. So al the knowledge must come from other vendors in your case from Sonic.
But there is hope you can use XI in a ESB way. You must only (add) configure the ESB parts. This is done by adding a service repository for example the UDDI server in combination with some BPML engine.
By adding it al together you can execute your business processes over multiple system platforms using SOAP in a synchronic way.
This is the basic concept of a ESB.
The answer to question 2.
I dont know if XI has build in support, but a know that there are free tools that can handle Canonical XML. So you can make a service your self to handle the Canonical XML documents.

What is SAP ESB (Enterprise Service Bus)?

Hi fellow sdners gurus I have been reading threads about SAP SOA and ESB.
I do not want to start a debate on wether XI is an ESB, but more of a statement to what is SAP ESB (if XI it is, then be it).
1) What is SAP ESB (Enterprise Service Bus) today (I could not find a clear answer to is)?
2) Who uses this SAP ESB in production currently and what kind of environment (i.e. strictly SAP backend systems, or combination of various vendors backend systems)?
Can someone share some light on this topic?
As a reminder, an ESB is expected to exhibit the following characteristics (source Wikipedia):
     It is usually operating-system and programming-language agnostic; for example, it should enable interoperability between Java and .NET applications.
     It uses XML (eXtensible Markup Language) as the standard communication language.
     It supports web-services standards.
     It supports various MEPs (Message Exchange Patterns) (e.g., synchronous request/response, asynchronous request/response, send-and-forget, publish/subscribe).
     It includes adapters for supporting integration with legacy systems, possibly based on standards such as JCA
     It includes a standardized security model to authorize, authenticate and audit use of the ESB.
     To facilitate the transformation of data formats and values, it includes transformation services (often via XSLT or XQuery) between the format of the sending application and the receiving application.
     It includes validation against schemas for sending and receiving messages.
     It can uniformly apply business rules, enriching messages from other sources, the splitting and combining of multiple messages and the handling of exceptions.
     It can provide a unified abstraction across multiple layers
     It can route or transform messages conditionally, based on a non-centralized policy (i.e. no central rules-engine needs to be present).
     It is monitored for various SLA (Service Level Agreement) threshold message latencies and other SLA characteristics.
     It (often) facilitates "service classes," responding appropriately to higher and lower priority users.
     It supports queuing, holding messages if applications are temporarily unavailable.
Your help is greatly appreciated.
Kind Regards,
Jean-Michel

I also think that same way. I do not know what is so apecial about BEA Aqualogic ESB and other market matured ESB products such as TIBCO & SONIC. The samples which BEA has given in their evaluation guide are very simplistic. BEA should do more to provide extensive knowledge/features about their Aqualogic line of products.

Publish BUS1065 object to Enterprise Service Bus (Tibco)

Dear forum members,
We are trying to find out if a concept we designed will work. Our goal is to publish a full business object e.g. BUS 1065 (Employee) to the Enterprise Service Bus (Tibco JMS technology).
We plan to customize change pointers to the BUS object, which will trigger a replicate of the BUS object. We hope to create an outbound iDoc which will contain the full BUS object. The ESB solution will trigger a JMS publish on receiving the iDoc.
Does anybody has experience with replicating a business object for a non SAP receiver? Will our concept work?
kind regards,
Richard

How to call proxy service at enterprise service bus using flex

Hi
I have a proxy service located at wso2 enterprise service bus. How can i call that proxy service using flex?
Regards
Minal

Hi Minal, I think you can communicate with wso2 using mx:HTTPService or mx:WebService, you just need to find out which services you'll be consuming and then create the flex app to present and interact with those services.

WLI as an Enterprise Service Bus (ESB)?

Hi!
BEA has previously sold WLI 8.1 as an ESB. See e.g. http://dev2dev.bea.com/pub/a/2004/12/soa_ibarra.html
Now that AquaLogic Service Bus has beed launched, it seems that the two products have much in common and some overlapping functionalities. E.g. both products have support for messaging and transformations.
For me it seems that the role of the two is not clearly defined.
What is new with AquaLogic Service Bus? What is the big difference? Why not just use WLI as previously described in the article by Ibarro?
Any thoughts? All input appreciated.

I also think that same way. I do not know what is so apecial about BEA Aqualogic ESB and other market matured ESB products such as TIBCO & SONIC.

Enterprise Service Bus

Dear All,
I was reading couple of article on what ESB is. But I was confused about the architecture of ESB. Does anybody have clear idea of what ESB is, what XI should provide to position it as a an ESB.
Please, do not point me to the sdn blogs/articles as I already them.
Thanks in Advance
Sreekanth

To share my understanding of ESB:
Any successful implementation of SOA/ESA requires applications and infrastructure to support it's principles. This means all the applications either should have the ability to expose their functionality as services or they need an infrastructure to expose the service. SAP XI would definetly help to expose the application functionality as services(web). I dare to call as a 'service container' in ESB terminology.
Besides the service repository functionality, XI also provides value added services like intelligent routing, mapping, auditing functionality etc.
And also distributed deployment(ESB quality for scaling) of some of the XI components are possible. Say for example, adapter deployment options(central, decentral), PCK, proxy framework etc.
On the security aspect of these exposed service, my understanding is that XI do not have much (like ws-security, xml signature, encryption, etc).
Business Process Modelling(BPEL4WS conformance) can be used for the service choreography. I am not sure whether CAF and VC supports BPEL standards.
Can anybody throw some thougths on this. And also what are the webservice management tools(deploying, declarative security etc) available in NetWeaver?
Best Regards
Sreekanth

Comparison between ODI and Enterprise Service Bus (ESB)

Hi,
As per my knowledge Oracle has provided two infrastructures, namely ODI and ESB for migrating data across applications.
My query is where I should use ESB and where ODI. Is there any comparison document available? I heard that for bulk data movement ODI is suggested by Oracle. Is there any benchmark exists for comparing these two tools?
I also want to map these tools with Oracle E-Business suite's conversion process. Is it possible to map each stage of a traditional Conversion Process (Data Loading, Validating, Importing to Oracle EBusiness Suite) using these tools?
Any kind of help/idea will be very much appreciated.
Regards.

Enterprise Service Bus Port Requirements

What are the minimum ports required to open to have ESB work with firewalls. The topology will be
users ------> |(firewall) ESB server ------> |(firewall) database server
HTTPS needs to go through a firewall to reach the ESB server. The ESB needs to go through a firewall to get to database servers. So far it looks like 443 through the first firewall and 1521 through the second. But what about JMS what port and where. Is there anything I'm missing. Can it managed via 443 or does 8888 need to be opened.

OSB 10.3 - Enterprise Service Bus Ant Deployment Feature

I am reading this doc
http://download.oracle.com/docs/cd/E12524_01/doc.1013/e12638/esb_ant.htm
and it talks about a file ESBMetadataMigrationTaskdefs.xml that I've seem in others web articles regarding building OSB projects using ANT.
What is this file? Where can I find it?
Does anyone have a step by step doc to how to build OSB projets with ANT?
Thanks in advance.

I am using OSB 10.3.1.
I tried to use this one as base for my own scripts
http://www.javamonamour.org/2011/11/updated-version-of-importpy-and.html (this is for 10.3.5)
and export from workspace, but without success yet.
I am able to export from a running OSB only.
basically I am runing this
as said here

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.
