SOA Question

Hi,
We have an application which has ORACLE DATABASE and BIZTALK is used to direct and call (orchestration) the Oracle PL SQL Packages. We want to get rid of BIZTALK in the application! Can ORACLE SOA handle what BIZTALK was doing for us? If so, which part of the SOA suite do we need?
See, I don't have any background in SOA or in Architecture per say. I'm a develiopper, So when it comes to all that SOA stuff ... I'm lost. What can I do to start understanding to way SOA works???
Please Help,
Marc

Depends on your use case, if you have long running processes which have lots of orchestration with lots of service calls then you would need to use BPEL ans well as ESB for service abstraction.
If your processes are short and require no state then you can use just the ESB.
cheers

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.

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.
Few links which may help you in understanding SOA and it's design patterns -

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.

Install SOA suite for IDM

Question about SOA suite installation
After RCU setup creates tablespace for Identity Manager and SOA- question: how does SOA install connect or know about the tables created by RCU. Because in the SOA setup process there was no configuration for Database server. So which component will guide the SOA to look into the appropriate tables, schema etc created by RCU.
Edited by: 968091 on Oct 30, 2012 5:31 PM

I think by "one of the message in the thread ", you are referring to Nayan's post:
Yes, you are right during SOA installation,It doesn't ask for the SOA related schema details.
It is being asked after OIM installation.Once you done with RCU, Weblogic,SOA, IAM/OIM installation you have to run below two configuration script
1. <IDM_HOME>/server/common/bin/config.sh --> Here you will create a domain and it will ask about all the schema details including SOA as well.
2. <IDM_HOME>/server/bin/config.sh -> this will allow you to set password for the xelsysadm(admin) user as well as design console and Remote manager setup.
---nayan
So, second one i.e. the one "OIM install/config" is used for setting the password for the xelsysadm(admin) user... The database related stuff happens in the first one itself i.e. <IDM_HOME>/server/common/bin/config.sh
THE FIRST SCRIPT PERFORMS DATABASE RELATED TASKS

WebCenter Content and BPM

Hi,
I have installed UCM and SOA BPM. Now I need to integrate this products.
Can somebody advice me how to do this?
Thanks!

Where can I create, deploy and activate BPEL process? This is more a BPEL (SOA) question than a UCM one. Are you sure that you have everything OK on the BPEL side?
In a nutshell, BPEL processes are best created in JDeveloper (it is a bunch of XMLs, so you could use other means to get them, but JDev will give you much better support, incl. deployment). A process is deployed on BPEL Process Manager (or BPM Engine); a J2EE app running on Weblogic.
UCM just reads what processes are available on BPEL PM. I'm just studying the matter in a bit deeper way, so it seems that a process must have a certain properties set to be recognized (see here: Re: UCM 11G and SOA 11G ). And, of course, the connection between UCM and BPEL PM (or SOA server) must be set first - I'm currently struggling with this one as ports to be read seemed to be filtered off, and I'm unable to connect to the server. That's why I'd recommend to narrow down the problem first.

Server.xml

I have been trying to run an ora:processXquery() transformation on my Soa suite.
The readme for the code says
"Add following XQuery libraries in "oracle.bpel.common" shared library
defined in <ORACLE_HOME>/j2ee/home/config/server.xml:
<code-source path="<ORACLE_HOME>/lib/xquery.jar"/>
<code-source path="<ORACLE_HOME>/xqs/lib/xqs-api.jar"/>
<code-source path="<ORACLE_HOME>/xqs/lib/xds.jar"/> "
I navigated to the server.xml and tried to find the oracle.bpel.common tag but couldnt find it. Do I have to reconfigure the installation for it?

Question on Insallation Approach for SOA 11.1.1.3

I would appreciate if any Fusion experts can answer this :
*Environment :OEL 5.3 64 bit, Oracle DB 11.1.0.7 , WLS 10.3.3, SOA Suite 11.1.13 and JRockit
I am setting up DEV environment
I installed Oracle DB 11.1.0.7 and RCU 11.1.1.3
I installed JRockit R27.5.0 for Java SE 6 for Linux x86-64” . While installing Web Logic Server 10.3.3 (generic) on 64 bit, I could see the Available JRockit 27.5 , I went ahead with that and I could install WLS. But while Installing SOA Suite I got this Error
java.lang.LinkageError: JAXB 2.0 API is being loaded from the bootstrap classloader, but this RI (from jar:file:/tmp/OraInstall2010-07-17_10-13-18PM/ext/jlib/glassfish.jaxb_1.2.0.0_2-1-7.jar!/com/sun/xml/bind/v2/model/impl/ModelBuilder.class) needs 2.1 API. Use the endorsed directory mechanism to place jaxb-api.jar in the bootstrap classloader. (See http://java.sun.com/j2se/1.5.0/docs/guide/standards/)
I think this JRockit does not support SOA Suite 11.1.1.3 Right now WLS 10.3.3 is pointing to the JRockit 27.5 (not supported for SOA Suite)
Later I installed JRockit Mission Control 4.0.1 for Linux X86- 64. [jrmc-4.0.1-1.6.0-linux-x64.bin] in /u01/app/oracle/product
Now I went ahead with SOA Suite 11.1.1.2 runInstaller and then SOA 11.1.1.3 patch runInstaller , which worked .
But while creating SOA Domain I could only see JRockit 27.5 in Available JRockit list , so I browsed and selected jrmc-4.0.1-1.6.0 from product directory I installed and I could successfully create SOA Domain.
I can start Admin Server & Managed Server . Admin Server & SOA Server is shown up in Enterprise Manager. So far , I am assuming what I did is correct ??
QUESTIONS: -
1. But WLS is still pointing to JRockit 27.5 . Will there be any issues/ errors later during Deployment ?
2. Should I change or point the WLS to JRockit Mission Control. Can I do this without UN-INSTALLING . Like changing PATH or CLASS PATH , Can anyone suggest how to do?
3. Are they any post installation steps I need to follow?
Thanks

Hi,
As you already have the cascade setup between Country and State set the default value for the state with SQL. The way to do it is use a presentation variable for country and use that variable in the state default sql as a filter. Sort the values and pick the 1st value in the sql. This would return the 1st value in the State prompt.
Let me know if this worked.

SOA Suite 11.1.1.3 installation - RCU question

Hi,
I installed SOA Suite 11.1.1.3 using the following steps:
1. Installed XE database
2. Created RCU - 11.1.1.2.1 using prefix "DEV"
3. Created RCU - 11.1.1.3 using prefix "DEV1"
3. Installed WLS 10.3.3 full install
4. Installed SOA Suite 11.1.1.2.0 in the middleware home created in Step 3
5. Upgraded SOA Suite from 11.1.1.2 to 11.1.1.3
My questions are:
1. Have I followed the correct steps? I did not receive any errors while installing.
2. Which RCU will be used by SOASuite 11.1.1.3? Schemas prefixed with "DEV" or schemas prefixed with "DEV1"? Is there a way I can check this information?
Thanks in advance.
Rgds,
Suhas.

Hi,
I successfully installed SOA Suite 11.1.1.3 too on windows 2003server
I first Installed oracle database11.2.0.2
then Created RCU - 11.1.1.2.1 using prefix "DEV",but no use the RCU 11.1.1.3
after Installed WLS 10.3.3 full install
Finally Installed SOA Suite 11.1.1.2.0 in the middleware home created in Step 3
and Upgraded SOA Suite from 11.1.1.2 to 11.1.1.3
so we hava the same steps.I run the em and console successful,and all the soa Components are run Operating normally!
and I found not any different between RCU 11.1.1.2.1 and RCU 11.1.1.3 on install soa suite.
I want to know you to Exchange our soa Experience!

File Adapter Question in SOA 11g

Hello,
just started with this soa stuff and looks like it can be very useful, i have a question:
i am doing a SyncRead within a bpel process and want the file is not necessarily there as soon as that process runs, so if it doesnt find it i want it to wait 5 seconds and retry and i want it to retry this up to 3 times...
what is the best approach to getting this done?
thanks

Hi,
You can put the invoke(synchRead) within a scope activity. Now add a catchAll activity, and within it add wait activity(5 sec') and replay activity.
The replay activity will always start the scope from the begining.
You will also need to add an if condition with 3 times counter. 1 branch will go to the above activities, and the second one will continue with the process.

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

Accessing application module in a POJO for SOA architecural question

Hi,
I have an architectural question. We have an app in jdev 11.1.1.1.0 that has app modules and jsf pages. It works great. I am of the thought that biz logic should not be contained in managed beans but in a POJO which is more tied to the model part. For example, if i have a method to calculate salaray, i would rather put that in a POJO that accesses appmodule to get the vo and related query instead of doing all this in a backing bean method.
I understand from Steve's tips that accessing app module directly is not a good idea (see "When should I use Configuration.createRootApplicationModule(), and when not?" at http://radio-weblogs.com/0118231/2003/08/01.html) .
ApplicationModule am = Configuration.createRootApplicationModule(
"com.oracle.apps.hr.personnel.HiringModule",
"HiringModuleLocal");
But then how do you go about making your app more modularized and decoupled that can expose a particular SOA service such as POJO.calcSalary() if you are not supposed to access app module in a pojo. Any other way to do it?
Another customer is asking pretty much along the same lines at Re: ADF BC 11 - best practice question

Have you looked at AM level service methods?
See 9.7 Customizing an Application Module with Service Methods
http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcservices.htm#sm0206
These service methods can be accessed from your JSF page with simple binding (see http://www.screentoaster.com/watch/stWUtcRkVLQ1FcRVxZXVhZ/service_method_on_am )
And they can also be exposed through a web service interface to the AM, see: http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/CreatingSDO-Demo/CreatingSDO.html

OSB and SOA Server (Mediator) Design question

As OSB is the strategic ESB and is used for external services does it make sense that all communication must go out via the OSB.
For example if I have a request that comes in gets routed through the OSB and then calls a backend composite which contains a BPEL that sits on the Oracle SOA server that calls multiple external services (CRM, SAP etc..) Would all the calls out from the BPEL then go back to the OSB and out to the external services (via proxy/business services.) This seems to add a lot of network hops to the whole architecture.
I can't really seem to find a diagram to explain this but an external service consumer could call the Oracle SOA stack that will come in via the OSB (for security gateway as OWSM 11g doesn't support gateway yet.) Then get transformed into the CDM and then passed on to the Oracle SOA server that has a composite service with BPEL that orchestrates multiple calls to internal and external services. The external ones requiring a transformation back into the service providers format.
How does this flow work?

If you are talking to external B2B systems you should use the Oracle B2B Server, have a look at this link,
http://download.oracle.com/docs/cd/E14571_01/integration.1111/e10229/b2b_intro.htm#CEGGAGJA
Section 1.6 in there gives a good example of doing just that. The OSB mediator is responsible for talking between CDM's in this case so it does some internal work, within one CDM set of services and then when ready the mediator translates from CDM to the format needed for the B2B. The B2B Server then does all the clever stuff needed to talk to the B2B partner.
In the internal case where the call is within the Enterprise the Oracle documentation states that there may be cases when doing this translation from CDM to legacy format may take place within the SOA server but recommends that it is normally done using the mediator in the same way as with partner calls. The 11g developer documentation states "The stated direction by Oracle is for the Oracle Service Bus to be the preferred ESB for interactions outside the SOA Suite. Interactions within the SOA Suite may sometimes be better dealt with by the Oracle Mediator component in the SOA Suite, but we believe that for most cases, the Oracle Service Bus will provide a better solution and so that is what we have focused on within this book."
Just what those exceptions are is an interesting question. If you have a CDM and all of your legacy world has translators you will spend all of your time hoping up to the mediator and back down maybe that is the exception. If everything is using the mediator then the SOA orchestration power is lost. If on the other hand most of your system lives within a canonical schema and there is one exception perhaps you make it pay the price for non-conformance.

Misc. questions about Oracles SOA software

Hello,
I am a computer science student at the Fachhochschule Aachen in Germany and i'm writing my master thesis about serviceoriented architectures.
Amongst other products i plan to present what oracle has to offer for SOA. But i'm missing some information, which i couldn't find at the website. I hope somebody can help me with my questions:
1) Is it correct that you only need the Application Server and the SOA Suite for a basic SOA setup? And the SOA Suite is included in the Enterprise Edition of the Application Server?
2) The SOA Suite contains the BPEL Process Manager. I just want to know which version of BPEL this tool supports: BPEL4WS 1.0, 1.1, WS-BPEL (2.0)?
3) In my thesis i describe several standards that help with serviceoriented architectures. I want to check if these standards are implemented and if they are, in which product, which version and how extensively? These standards are:
- WS-Policy, WS-Adressing
- JBI (Java Business Integration)
- SCA/SDO (Service Component Architecture/Service Data Objects)
- WS-CDL (Web Service Choreography Description Language)
Are there other important (open) standards i didn't mention (other than the real basic stuff, WSDL, SOAP etc)?
4) What tools does Oracle provide for testing the services and processes?
5) What support does Oracle provide for new customers, that are building their first SOA?
Every help would be appreciated. Thanks in advance.

Question regarding Composite granularity in SOA Suite

I have a question about service granularity in a SOA Suite composite. In your experience, what is the best way to implement an Enterprise Business Service in SOA Suite?
Say I have a service interface/wsdl that looks something like:
Customer
+ getCustomer
+ createCustomer
+ updateCustomer
+ .....
Would the operations on the service be best implemented as BPEL processes each living in their own composite, or as multiple processes in one composite with a mediator(based on the ebs wsdl) in front of them? I'm also using OSB, so I could do the routing there to each of the separate composites if I break up the operations into a composite for each. But that seems like the amount of composites would become unmaintainably high.
If I use the mediator to expose the ebs wsdl, then I would just use OSB for virtualization, throttling, etc.
Not too sure which way to go with this design, but any experienced input is appreciated. I did notice that AIA implements each operation as a separate composite.
Thanks.

As per the AIA architecture we should use Mediator in EBS layer, because of below reasons.
1. OSB is not part of SOA until 11g,
2. You have to re write the code for exposing EBS in OSB Layer, thats a huge work.
Both Mediator and OSB does the same thing, ofcouse there are some differences
As per your design if you use OSB for virtualization, that is fine, but you will be having one more layer of virtualization before it hits the actual composites, which will definately hit the performance, extra care we need take for OSB layer.
In my current project, we tried both the approach that you wanted to try.
Approach 1 : Exposing EBS in OSB Layer.
Tried rewriting the EBS wsdl because the port information will not be available by default, without that we will not be able to create proxy services in OSB.
Then for how many wsdl files you will rewrite the code, then you need to update the MDS as well with those.
Did a small POC and then decided to go with as is. Probably we will have OSB layer in AIA 12 g
Approach 2 : We are using OSB wrapper for thirdparty web services and adapter services not the provider abcs services. I feel this is overhead.
Thanks,
Vijay

OSB Install question on SOA 11g

Hello Experts,
I have installed SOA 111g and below is the environment:
Web Logic -- 10.3.6
SOA -- 11.1.1.6.0
AIA -- 11.1.1.6.0
Created Doiamns, configuration completed and users are testing it..
Forgot to install OSB and Oracle recommends that we install OSB first, before SOA.
Question
Is that ok to install OSB in the same location of SOA, at this point??
Thanks
Rgds
Natrajan

Natrajan,
It is just an recommendation or good approach to Install Osb first before we install Bpel.
But In case you have already installed SOA , you can go ahead and Install OSB . It should not matter to you.
Hoping that this is your local machine and I am pretty sure that It will work fine. Since my OSB is topped on SOA Suite.
Thanks
Tirumala Dixit.
