JCA adapters documentation status

Trying out BPEL PM, I first need to build little POC for quite technical interfaces, loading files in DB ...
I need to go beyond the possibilities of the FileAdapter and the DBAdapter that are included in the tutorials with BPEL PM. I see in the forum the doc was due with a next release. What is the current status ? Anything available yet ? For example, I want to use FTP instead of polling a directory.
When do we expect a downloadable version of Jdeveloper that will include wizards to develop web services based on these adapters ? Or something like that ?

Olivier,
I do not have visibility into the doc timeline at this point (specially for advanced feature like the JCA framework).
My recommendation: send us an email at [email protected] and we will try to enrole you to the BPEL PM 10.1.2 early adapter program so that you get access to the JDev designer which include UI for all the adapters.
If that is not enough, we can send you the example of one of the JCA adapters and you can investigate building your own.

SOA Clustering with third party JCA Adapters

Hi,
We are planning to do clustering for our SOA suite which has third party JCA adapters. Some BPELs inside SOA suite will listen to the third party JCA adatper which will listen to third party system and some bpels are listening to the DB adapter for polling the records in DB.
Say if adapter1 is in node1 is downloading that message from third party system which is big in size and meanwhile if adapter2 in node2 can also start to download the same message which end up in duplicate messages getting download. So in clustering environment, how to make sure that the BPELs wont pick up these duplicate messages from the third party system/ DB where they are listening to it?
(adapter1 and adapter2 are the instances of the same adapter)
Is there any way in BPEL to identify if it is duplicate message which is already processed by the BPEL or not? If not is there any other way?
Thanks
Sree

Thanks for the info.
But the links you provided talks about active-passive cluster configuration. But I am looking for the active-active cluster configuration where I have multiple instances of the JCA adapter running on different nodes. I want to make sure that the message picked up by one JCA adapter instance running on node1 should not be picked by the other JCA adapter instance running on node2.
Thanks
Sree

WebLogic - how to get installed JCA adapters

Hi,
I am not sure if this is the right place to ask but I couldn't find any other appropriate forum, so I'll just drop my post in here.
I would like to know how I can get the list of installed JCA adapters from my application which deployed onto WebLogic server. Is there any WebLogic api available for that? Thanks in advance.
Regards,
K.Hein

I am looking for this answer as well.

Integration of own JCA adapters in OSB

Hi,
Is it possible to integrate our own JCA adapters in the OSB via the JCA framework?
If yes, how can the corresponding WSDL be automatically generated?
thanks

The Oracle Service Bus JCA transport lets you interact with the following JCA-compliant adapters:
Oracle Applications – Oracle Applications services can send and receive messages from
Oracle E-Business Suite using available interfaces
Oracle AQ – Oracle Advanced Queuing services can send and receive messages from
Oracle AQ single or multiconsumer queues
Oracle Database – Oracle Database services can send and receive messages from a table or
execute a stored procedure

Fault Types for JCA adapters

What are the fault types(local part name) in the namespace: http://schemas.oracle.com/sca/rejectedmessages .
I want to handle faults for FTP adapter for rejected messages.But I don't know what are the fault types defined for FTP adapter(JCA adapter).
Can you please point me to the document where it is documented so that I can proceed with developing Faulthandler for FTP adapter.
For 11g, I need to use fault-policies.xml and fault-bindings.xml.
To define the faultname inside fault-policies.xml file, I need this above information.
Thanks,
Prabhanjan

Hi Prabhanjan,
The local part name should be same as the service name i.e when you define an adapter two files are generated <service_name>.wsdl and <service_name>files.jca.So this <servicename> should be used as the local part name for the fault-policies.xml and in fault-bindings.xml it should be as below-
<?xml version="1.0" encoding="UTF-8" ?>
<faultPolicyBindings version="2.0.1"
xmlns="http://schemas.oracle.com/bpel/faultpolicy"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<service faultPolicy=[id in fault-policies.xml]>
<name>[service_name]</name>
</service>
</faultPolicyBindings>

Using JCA FTP and File Adapters to transfer files as attachments

I am trying to develop a flow that picks a file up using the JCA FTP adapter and writes it using the JCA File Adapter. I can get this to work using opaqeElement but the issue I have is that the files that will be transferred are regularly very large > 1 GB and using the opaqueElement simply results in a OutOfMemoryException.
Reading the Adapter documentation it seems that Reading/Writing file as an attachment may be an answer. I therefore did the following.
. Created FTP Read and File Write adapters in JDeveloper
. Inmported this in to OEPE
. Created Proxy Service and Business Service and wired them together
The problem i am having is that even though there is no error and the file is being read on the FTP server, the resulting file only contains that attachment details, the file is not a copy of the file that was picked up from the ftp server.
I am assuming that this behaviour is not correct and that the file should be transferred in its entirity. Unfortunatly the documentation is not very detailed and I cannot find any examples on the internet.
Can anyone offer any advice or even better suggest where I can find an example.
Regards

System resources are finite and have a threshold limit for processing. The Oracle SOA Suite, dependent on system resources, also has certain size limitations, largely due to the underlying resources beyond which the system cannot process incoming requests.
For example, Oracle JCA Adapters can process large payloads but the Oracle BPEL PM consumes huge memory when processing large payloads, which can cause OutOfMemory conditions and affect the whole system.
You can try File ChunkedRead option.This will read your large CSV file in chunks so chances of memory out will be less. You can define your own chunk size.
This is a feature of Oracle File and FTP Adapters that uses an invoke activity within a while loop to process the target file. This feature enables you to process arbitrarily
large files. See below link's section "4.5.5 Oracle File Adapter ChunkedRead"

Status for project documentation

Hi Experts
Just wanted to check u2026
If there are 10 status for project documentation defined in the system out of which only 5 are applicable for my project and hence I want to hide( not just make it gray u2013 I know this I can manage using restriction @ S_IWB_ATTR )..
How and where I can configure this only for my project and not for entire system ? .
Cheers
Aditya

Hi
Simply create a documentation type and assign a status schema to it with required set of status values in the schema
moreover if you make the Check on Global Indicator in the Project Documentation Template where you assign schema to your documentation type their if do the Check it is available to all but if you dont make the check it is available for your project only so
you have to assign it after creating from Unused Documentation types to your project documentation type library
so steps will be
create a documentation status schema via spro
goto project in solar_project_admin and here create the doc type
assign the doc type with new status schema .......also dont make the check for global
save and return to project screen and here assign the doc type from unused zone to your available proj doc types
Hope it solves

OSB - Business Case for Adapters Vs Transport

Hi
1. Can you please explain me a business case on when one should use Db/JMS/FTP/File Adapter in OSB and when should one go in for equivalent transports for configuring Business/Proxy services? Would be great if you could point me to some documentation on which approach should be chosen over the other/any benefits that a particular approach has etc..
2. Also is there some Oracle Documentation available on comparision between OSB and BPEL? When should a particular product be chosen? I tried searching for an example with a business scenario which provides details on when to use OSB and when to use BPEL but havent been able to get much info.
Thanks!

Can you please explain me a business case on when one should use Db/JMS/FTP/File Adapter in OSB and when should one go in for equivalent transports for configuring Business/Proxy services? Would be great if you could point me to some documentation on which approach should be chosen over the other/any benefits that a particular approach has etc.. For DB, you have to use DB adapter in OSB beacuse there is no seprate transport defined for DB. For FILE, you have both options - FILE transport and FILE adapter (in OSB 11g). FILE transport should be the preferred option (never seen documented anywhere) as it has been designed as part of the product and hence should be faster (although never comapred). For JMS and FTP, you have to use respective transports defined in OSB because OSB does not support JCA adapters for FTP/JMS (you may refer - 25.2.1 Adapter Support
at http://download.oracle.com/docs/cd/E14571_01/doc.1111/e15866/jca.htm#BABBICIA)
2. Also is there some Oracle Documentation available on comparision between OSB and BPEL? When should a particular product be chosen? I tried searching for an example with a business scenario which provides details on when to use OSB and when to use BPEL but havent been able to get much info.OSB is a dedicated routing product and must be used for scenarios where only routing is required along with light transformations. Being a stateless product OSB can bear heavy load as well as gives better performance. BPEL can do what OSB does (to a certain extent) but being a statefull product it is much slower than OSB and should be used only for scenarios where process orchestration/human workflow intervention is required.
OSB being a service bus, can mediate among almost each and every kind of protocols but BPEL would need adapters for such mediation.

SAP NetWeaver CE 7.1 EHP1 does not support version 1.5 JCA?

Hi,
I've been following the documentation of SAP NetWeaver CE 7.1 EHP1 regarding creation of a version 1.5 resource adapter. When I finally got to "Add/Remove projects" in the server view to test my adapter, I get this error:
The server does not support version 1.5 of the J2EE Connector module specification
Is this true? Then why does the documentation explain how to do it?

Hi Johan,
I agree with you that this does not seem clear enough throughout the Resource Adapters documentation.
Generally speaking about the Developer Studio, there are two equivalent options to add your project (be it JCA, EJB, Web, JPA, etc.) to an EAR project:
While creating your project, you can specify that you want it to be added to an EAR project - either a new one or an existing one (you can create the new EAR project also in the meantime, while creating your JCA project). This is done using the "Add your project to an EAR" checkbox and the relevant dropdown list and button...
Create your project. Then create a new EAR project and specify which projects you want to be included in the EAR.
As I promised, we will improve that part of the documentation for the next release.
Thanks again, and best regards,
Yordan

JCA Support in WLS 7.0... is WLI required?

          I've been digging into the documentation of the Administration guide and documentation
          about WLI. WLI makes it sound like it is required to use JCA Resource adapters.
          I can't find any topics in the administration guide for WLS which cover JCA.
          With this I assumed that WLI is required, but when I read thru messages here
          I find ones that sound like all you need is WLS and the control pannel has options
          for JCA.
          Can anyone clear this up for me.
          Thanks,
          Michael


Hi Michael,
          As per as I know, If you want to work with JCA adapters developed by BEA
          weblogic by using WLI. You can install specific WLI and can see/test the
          functionality with Weblogic server.
          But if you want to work with your own JCA adapter implementation to
          specified EIS like any RDBMS, MQSeries like systems, You can start
          implementing the JCA to develop adapter without WLI also.
          Please ignore this, if this is not answers your question.
          Thanks

Error status in JMS adapter - sync / async brigde. Message processed ok

Hi guys
I'm having som trouble with my scenarion. I'm sending sync message from SAP backend to XI using proxy. From XI onwards to JMS adapter async (and the other way around for the response message).
This works OK. However i have a status error in my RWB on the JMS adapter. There is er red exclamation mark and a text saying:
Correlation ID 'XXX' of JMS request message 'ID:yyy' saved that correponds to XI message 'XXX'
How do I get my adapters in status green?
Kind regards
Martin

Hi Kai
Oh - OK
Settings are:
Receiver JMS channel:
Set JMSCorrelation to: XI Message ID (MessageID)
Store JMS CorrelationId of request: Mark
Sender JMS channel:
Set XI Message ID (MessageID) to: GUID (Recommended Value)
Set XI Conversation ID (ConversationID) To: Stored JMS CorrelationId of Request.
Kind regards
Martin

Advantages JCA DB Adapter vs EJB

The recent acquiring of Bea by Oracle unveiled a bunch of JCA adapters to do connectivity to (backend) resources. One of them is the DB Adapter. A wizard in JDeveloper creates a JCA adapter that internally uses Toplink. Although this looks like a nice approach still I have some hestitation to use it. You could decide to do the interaction with the database based on EJBs (or other more direct approach). No one in our team has any experience with JCA what so ever. So when the wizard or generated adapter fails it will be quit a problem for us.
The wizard based approach of the adapter gives you quick results. The downside is the restriction of what the wizard offers. If it does not fit you can edit the toplink stuff. But this would mean you have to dive deep inside the JCA internals. From a wizard to that is quit a big "jump". The need for this OR mapping somewhat puzzles me anyways although I can image that building a configurable adapter based on such a framework makes life easier (It is always good to combine existring stuff into a new product than building it all from scratch).
If this is the way forward into connecting with a database from OSB (in our case) it might be needed to invest in this approach. Questions are raised why we cannot use an approach that does not introduce a new stack of technologies (JCA, Toplink). We will be connecting with a single big Oracle database/Schema. Currently we are doing simple queries or calling PL/SQL functions. So looking at the current requirements the wizard will be able to handle that.
Does anyone has an opinion in this or some guidelines/best practices.
Regards
Frank (ALSB/J2EE background)

The need for this OR mapping somewhat puzzles me anyways although I can image that building a configurable adapter based on such a framework makes life easier (It is always good to combine existring stuff into a new product than building it all from scratch).The value addition is highest when use-cases require connecting to various DB instances (eg Oracle, Sybase,DB2 etc). In such cases DB adapter will allow you to develop application very fast, with out spending much time in understanding and coding for each DB. Other value addition of using DB adapter is it allows getting inbound events from DB and has support for multiple strategies. As with any other technologies, improvements in productivity are accomplished by constantly adding technology stacks. So toplink/JCA is one such stack which improves productivity for accessing DB. There might be some rare cases which DB adapter doesn't support. In such cases we can always go with JavaCallout/JDBC approach.
Currently we are doing simple queries or calling PL/SQL functions. So looking at the current requirements the wizard will be able to handle thatDB adapter should well suite this case.Only issue you have raised is new stack being introduced which needs mastering.
These productivity improvements change from case to case. Eg. A use case that will only require requiring only one simple insert into Oracle DB is better coded with JavaCallout/JDBC rather than using DB adapter. A use-case that requires that we poll on table and get the update on table is very complex to implement by code(ie we have to write the logic for the polling /avoiding duplicate records) . In such cases it makes sense to use DB adapter rather than write java code.
At the end it boils down to deciding if the new stack is worth adopting given the productivity improvements it can bring.
My two cents

OSB JCA Adapter performance issue

Hi,
We have to use OSB as an ESB at integration level which need to populate the result from local services e.g. from DB as well as from external services. Actually we need to use switch [split -join] and connector [individual proxy for individual services] features.
As for external services, we do not have questions but to access data from local system e.g. Database, whether it will be a performance issue in OSB, in case if we are using JCA Adapter and exposing it as a service? Because some one objected that accessing JCA layer in OSB will be a performance issue.
If some one can shed the light on it, it will be great.
Thanks & Regards,
V D

Hi,
Have a look at the Developer Guide for OSB... Oracle JCA Adapter for Database is supported... Have a look at the limitations, there's nothing mentioning performance...
http://docs.oracle.com/cd/E23943_01/dev.1111/e15866/jca.htm#i1110405
Also have a look at the following blogs... One of them even suggests that jca performs better than xquery with fn-bea:execute-sql...

http://reallifeserviceorientedarchitecture.blogspot.com.au/2011/09/oracle-service-bus-osb-and-jca-adapters.html
If you are still in doubt open a SR with Oracle Support...

Jca and jms

hi,
i ned to impliment a jca (java connector architecture) in jms,
help me.
thanks

Hi,
You're going to need to be a bit more specific in your question.
Why do you need to write one? Most JMS providers come with JCA adapters, and Sun have two open source JCA adapters which will work with a variety of JMS providers. Take a look at

JCA Adapter Postprocessing with OSB

Hi,
I am using JCA file adapter with OSB to generate flatfile output from xml (nxsd). I would like to know if it is possible to use JCA adapter post processing with OSB. (JCA pipeline and valves). Please let me know if you have tried this.
Thank you
Matt

Pre and post processing is not supporting in JCA Adapter for File/FTP certified on OSB. Check section 25.2.2.3 Oracle JCA Adapters for Files/FTP Limitations in below link.
http://docs.oracle.com/cd/E23943_01/dev.1111/e15866/jca.htm#OSBDV910
However, according to below link it does work nonetheless. I havnt tried it, may be you can try it out as given in the link below and let us know.
