SOA HA Design

We are designing SOA for high availibility. My understaing is we will be doing active-active and need to install oracle AS, esb abd BPEL on both nodes. I am searching through Oracle docs and couldnt find whether hardware clustering is required or not? Can someone please help.The docs talk about AS clustering and referrs to Multicast Replication between nodes. My question is how this is acheived ?
Edited by: user5475931 on Sep 17, 2008 3:18 PM

We wanted to use Oracle SOA 10.1.3.3.0 1 year ago in HA active-active mode and ended up running 2 isolated nodes with the same processes deployed due to high amount of bugs in cluster. Now with patches oracle releases more frequently than back then situation got better, but I think still not all bugs we discovered were fixed, therefore have a backup plan with 2 isolated nodes. Make sure you apply the latest MLR patch from metalink. I have MLR#12, but I think there is a newer one. Without at least MLR#12 using SOA in cluster is useless.
Oracle SOA also likes to download XSDs from the internet from time to time, so make sure you either deactivate it somehow or provide a local mirror.

SOA Application design

Hi All,
I want to create a SOA Suite application. Is there any analysis and design phase like J2ee application. eg: J2EE application I will use UML and OOAD concepts after requirement analysis phase.
1) What steps do I need to carry out for analysis and design in SOA Suite application?
2) Is there any good book or starting point on SOA design.
Thanks

Hi,
For beginners Oracle SOA Suite 11g R1 Developers Guide by Antony Reynolds is really good...
do follow specific oracle documentations for advancement...
do check this link for documentations of oracle on SOA Suite...
http://download.oracle.com/docs/cd/E17904_01/soa.htm
Oracle JDeveloper is the primary development tool for building SOA Suite Applications...

SOA Architecture Design

Hi All,
I am trying to start new integration project where I can use SOA arch as by core design and using various
technologies to achieve this,
but I would like to know what are the design problems that I will be facing to make it successfull project:
I am planning to use Webservice for loose coupling.
I would like to achieve High Availability- please help how to achieve this with and without ESB.
I will make sure that all the services exposed and consumed are coarse grained, and avoud fine grained services.
Design invocation program to optimally use service invocation to avoid unnessary network bandwith utilization.
I am planning to use every feature mentioned by JSR-208(JBI)/JSR-312
like BPEL engine,Protocal Translation,Business Chreography,Business Composition,Business Rules,Service Routing,SE and BC.
Please help me to put your experience to how and what to use and what to avoid and reasons
like you have faced in your experience supporting these items.
Also I would like to know which or what would be best way to perform Testing for SOA
How to create build process to reduce deployment using ant or maven or appfuse.
How to overcome performance issues because of SOAP and what would be the alternative way to achieve SOA without webservices
might be messaging using JMS and MQ Series-how to achieve sOA here ? if so where will ESB fit.
My problem domain:
I have many applications build using layered arch(presentation layer,business layer,DAO layer) in 3 tier and 2 tier topology.
I have few legacy systems like ERP systems and AS400 systems
I have no experience in EAI.
I know I am throwing all Technologies but I am bit confused to what to choose when and where.
Appreciate your support.
I want to build robust integration platform, please advice how can I achieve this step by step.

hi tom,
first: as this is a very very general question the answer for you would be at least 120 pages ;-) (from my point of view)
please consider asking more specific questions!
a view things:
1) SOA does not have to deal with SOAP or webservices
Webservices can be done in memory (no http) and might perform better
if you have to deal with ws consider using a ws layer that is good for (transparent failover, loadbalancing.....
2) try to make your interfaces expandable (e.g. optional fields ....) so that consumer of older versions are compatible with consumers (newer versions)
3) be aware that BPEL (from my point of view) is very slow when doing all the stuff as it is interpreted always ...
4) give us an idea of the volume you have to deal with
5) which version will you use?
6) from my point of view HAV is simplier achieved and managed by JMS HAV
7) how will you communicate with e.g. AS400?
so much more to ask but those are the most relevant ones from my point of view....
can you give us your vision?
a good starting point would be:

SOA JMS design question

I have a SOA11g application with the following
Web Service ---> Mediator ----> JMSAdapter (Produce Pattern)
(Consume Pattern) JMS Adapter ---> Mediator ----> DB Adapter
This application will receive XML messages from the web service and store it in a JMS topic (persistent) and later distribute it among the consumers. I am trying to implement a simple use case wherein , when the message is received from the webservice and persisted in the JMS topic. I need to send an acknowledgment back to the external system. How can I implement it. Will the JMS request/reply pattern be of any help? Is there any similar example available.
Thanks

I have a similar situation here and using mediator to consume_message from a AQJMS resource. It does not seem to work.
Here's what I did
- Configured AQ on a different server than SOA suite
- Set up a datasource in SOA server to connect to database having the AQ, used Oracle Thin XA driver. JDBC datasource user same as the AQ owner.
- Created a JMS module.
- In the module, created a Foreign Server resource and with the default targeting
- Using the foreign server’s General Configuration tab, set the JNDI Initial Context Factory to oracle.jms.AQjmsInitialContextFactory and added the datasource property to the JNDI Properties field and set its value to the JNDI name of the data source created for accessing AQ.
- Set up the foreign server’s connection factories. Remote JNDI Object javax.jms.XAQueueConnectionFactory
- Set up the foreign server’s destinations using its Destinations Configuration tab as Queues/<AQ queue name>
- Created a composite to read from JMS adapter pointed to the JMS Destination local JNDI, using a mediator
(Consume Pattern) JMS Adapter ---> Mediator ----> TIBCO Adapter
Deployed composite successfully, but it does not dequeue the messages from AQ neither thorws any fault. In fact no instance were created
This does not seem to work, can anyone help

NEWBIE SOA Question:Appl Development for SOA

This question may have been answered elsewhere; if so, my apologies.
As a newbie to SOA, I am trying to wrap my head around the question of how app. development for SOA differs from traditional models. For example, non-SOA environments there are few external considerations when coding a process,
but in SOA environments, I understand everything is a service.
Can someone provide a few code snippets as to how they would look in each environment?
I have read through several documents on SOA and have done the SOA tutorial, etc. but I have yet to see a side-by-side comparison of application code in SOA and non-SOA environments.
How would an architect plan the translation and mapping of business objectives and functional requirements into a technical solution for SOA, architecting the SOA solution ?
I would really appreciate any pointers (links to articles, etc.) in this direction. Thank you.
Gordon

Hello Gordon,
SOA (Service Oriented Architecture) - as the name indicates, it's design is based on services. SOA is another integration technique which is used for small scale integration. SOA is an approach to have software resources in an enterprise available and discoverable on network as well defined services. Each service would achieve a predefined business objective and perform discrete units of work. The services are independent and do not depend on the context or state of the other services. They work within distributed systems architecture.

EJB and SOA question

Please I want to clear a little confusing on this:
Is creating a web service endpoint on a group of stateless session beans enough to say that they are SOA complaint.
Explanation:
==============
I have a business component built using EJB 3.0 technology. But I want to extends access to my services using web services. The question here refers that if I now build webservices on my existing services, does that in any way imply SOA - ward design.

The question here refers that if I now build webservices on my existing services, does that in any way imply SOA - ward design.The fact that it's a stateless session bean implies that it's already a "service". The problem is that it's Java only, because it depends on RMI, and any Java classes you have in the method signatures immediately couple the clients to the service.
What a "web" service will buy you is: XML over HTTP instead of RMI over IIOP as the wire protocol, and looser coupling using "contract first" XML instead of Java classes in the interface signature.
You're pretty much re-wrapping the functionality so you can expose it as a web service. I would say it's no more or less of a remoting technology than RMI. Servlet, EJB, web service, etc. - I would keep the remoting details out of the class that actually did the work and treat the way I deployed it as wrapping.

Is a BPX a Process Steward?

My colleague Aiaz Kazi forwarded this to us:
<a href="http://jkobielus.blogspot.com/">James Kobielus' Blog</a>
The piece Aiaz highlighted, was a discussion he had with the blogger who calls the BPX a Process Steward. I've quoted it below as it speaks to the role definition "grappling" we are working through here on this forum.
Your comments about this are welcome.
"I had a discussion on this same topic yesterday with Aiaz Kazi of SAP, here at SAPPHIRE 06 in Orlando. Many of their customers are grappling with the proper definition of the diverse roles in governance of SOA that leverages SAPs Enterprise Services Architecture (ESA), which is implemented in its NetWeaver platform components, mySAP applications, and diverse composite, vertical, and horizontal apps and business processes.
What Aiaz was describing is a new SOA governance design-time role that sits halfway between the IT process architects and the business process analysts (i.e., the tech and business wonks who use their respective visual development and flowcharting tools to specify SOA-enabled business processes at various levels). This intermediate role essentially catalyzes consensus between the business process analysts and the IT process analysts concerning the eventual process, but doesnt actually get involved in the fine-grained architecting of the processes.
Instead, this role is more of a process steward (my term) who makes sure, whatever new process emerges, that it reuses existing business processes to the maximum extent feasible. The process steward cracks the whip and just says no when IT process architects and business analysts attempt to create new, end-to-end, stovepipe workflows that overlap with existing processes, either in their entirety or in significant roles, routes, and/or rules.
In other words, the process steward role enforces reuse of existing business processesSOA-stylewhen developing new processes. The process steward oversees the SOA governance processthe design-time workflow or collaborative process--under which business governance structuresas defined by IT process and business process architectsare crafted, revised, and optimized."

with German (or to be more precise Austrian) as my native langugage I seem to fail to assess the full meaning of the term 'steward' and maybe just because of this feel uncomfortable with it.
To me 'process steward' sounds as it were some subordinate role, something like governanvce accountant, someone counting reuse numbers, annoying both the business analyst and the IT architect.
Nevertheless I like the idea of
This intermediate role essentially catalyzes consensus between the business process analysts and the IT process analysts concerning the eventual process, but doesnt actually get involved in the fine-grained architecting of the processes.
.
Therefore I'd coin this role a process mediator, someone who gets IT, business analysts and users together and helps them to reach a common understanding and if necessary mediates with respect to different perceptions, requirements, levels of knowledge and most notably ontologies.
just my 2 thoughts,
anton

Newbie Development Question

I'm evaluating the G6 portal product and I'm working with the development tools to determine how easy/hard it will be create and maintain portlets. After reading through some of the documentation, I'm a little concerned. I've been trying to develop just simple portlets like "Hello World" using .NET and what I'm find is that any portlet that I design cannot be tested from within the IDE if I'm referencing the portlet API.
I know that that last statement can't be true. And, I've seen references to where I need to create a remote server and point that at the folder where I'm doing development on my machine. However, I haven't been able to find instructions on how to do that.
Can anyone point me in the right direction?

PS3 issues with roles & custom policy

Hi
We are pursuing two cases with Oracle support for SOA suite Ps3 ( on linux platform) - anyone who faced the same issues?
1. Custom policies - in PS2 , everything works fine. In PS3, if we click on create in the policies page - it takes a long long time to show the create page. Sometimes it times out as well
2. Weblogic vs SOA roles. In PS2, one person can get weblogic monitor role & SOA deployer/designer role & do a composite deployment. In PS3, for a SOA deployment, Weblogic admin role is needed ( irrespective of the role defined in FMW EM) .
Thx
Jay

You should be able to deploy projects with a user having operator access. Admin role is not required for deployment. You may refer -
http://download.oracle.com/docs/cd/E17904_01/integration.1111/e10226/appx_roles_privs.htm#BABIHDFJ
In PS3, if we click on create in the policies page - it takes a long long time to show the create page. Sometimes it times out as wellMay be an environment specific issue. Better track it through a SR.

AIA - do i have to install AIA on all developer desktops ?

We are starting on developing AIA based integration solutions and was wondering how can we acess the EBO/EBM/EBS available out of the box from a central server ? Is it possible to access from central server or do we have to install/copy the AIA components and artifacts on every single machine ?

Hi user9514124
Yes of course it is possible "access from central server" and do not have to install in every workstation.
AIA (and by this i am presuming AIA Foundation pack or any of the PIPs) should be installed in the same server as the Oracle SOA Suite.Also it is a AIA install pr requisite that Oracle Service Registry is setup in the same server.
The Service Registry (an UDDI Registry) will take care of managing the AIA artefacts(EBO/EBS). In the JDevloper you hav to make an UDDI Registry connection to the server to access the EBS etc.
You must understand that AIA is a standardization methodology which helps in better SOA governance and nothing more than some standard skeletal code snippets (and something more) for easier and standardized SOA process design.

How to use SOA Suite in conjunction with SOA Analysis and Design Tools

Hi everybody,
I am a novice in this field and I need some help regarding integrating analysis and design tools with SOA Suite.
We used to analyze and design with Oracle Designer and use its powerful form generator to develop a system. It almost covered all the software lifecycle and kept the traceability between anlaysis,design and implementation.
I have studied about the SOA concepts and read some papaer about SOA Suite. I have also installed the SOA demo based on SOA Suite and I found it absolutely amazing, but my problem is that It seems oracle does not have any tools for SOA Analysis and Design. am I right? if so, How can we analyze and design a system based on SOA concepts and implement it using soa suite in such a way that keeps traceability? What tools is used for this purpose?
It seems that IBM have some tools like Rational Software Architect and Rational Suite which enable people to design and analyze based on SOA concepts and then generates some pieces of code (like oracle designer in old days) but is it possible to design in these tools and then generating codes for SOA Suite ? (for example generating a bpel file from a design model)
As I told before I am a novice in this field and I would be so grateful if other users can share their expriences regarding this matter.
Any help would be highly appreciated.
Thanks in advance,
Navid

SOA real-time design question

Hi All,
We are currently working with SOA Suite 11.1.1.4. I have a SOA application requirement to receive real-time feed for six data tables from an external third party. The implementation consists of five one-way operations in the WSDL to populate the six database tables.
I have a design question. The organization plans to use this data across various departments which requires to replicate or supply the data to other internal databases.
In my understanding there are two options
1) Within the SOA application fork the data hitting the web-service to different databases.
My concern with this approach is what if organizations keep coming with such requests and I keep forking and supplying multiple internal databases with the same data. This feed has to be real-time, too much forking with impact the performance and create unwanted dependencies for this critical link for data supply.2) I could tell other internal projects to get the data from the populated main database.
My concern here is that firstly the data is pushed into this database flat without any constraints and it is difficult to query to get specific data. This design has been purposely put in place to facilitate real-time performance.Also asking every internal projects to get data from main database will affect its performance.
Please suggest which approach should I take (advantage/disadvantage. Apart from the above two solutions, is there any other recommended solution to mitigate the risks. This link between our organization and external party is somewhat like a lifeline for BAU, so certainly don't want to create more dependencies and overhead.
Thanks

I had tried implementing the JMS publisher/subscriber pattern before, unfortunately I experienced performance was not so good compared to the directly writing to the db adapter. I feel the organization SOA infrastructure is not setup correctly to cope with the number of messages coming through from external third party. Our current setup consists of three WebLogic Servers (Admin, SOA, BAM) all running on only 8GB physical RAM on one machine. Is there Oracle guideline for setting up infrastructure for a SOA application receiving roughly 600000 messages a day. I am using SOA 11.1.1.4. JMS publisher/subscriber pattern just does not cope and I see significant performance lag after few hours of running. The JMS server used was WebLogic JMS
Thanks
