HTTP Adapter in BPEL or ESB

hi,
i need to know if there is any adapter available to call a HTTP service or any other alternative to call a HTTP web service.
Please reply as soon as possible.
thanks in advance,
Preeti Agarwal

Just for your information it is recommended when dealing with Batch type processing that the you do not use BPEL variables larger than 5MB.
Therefore is this is the case it might be worth considering a mechanism (as described above) to de batch the process to provide a flow of data rather than a big hit of data.
Hope that Helps
Dave

Forcing HTTP comm between BPEL and ESB

Hi all,
for demo purposes, I'd like to disable the internal and non-HTTP communication between BPEL and ESB when both are deployed on same OC4J container.
I do not want to modify any WSDL but, if possible, disable somehow such internal communication. AFAIK, there was a property named "optSoapShortcut" in 10.1.2 but it no longer exists in 10.1.3.
Any clues?
TIA

Hi.
Sometime ago I tried to work with a BPEL property named preferredBindings, but it didn't work at all.
WSM Gateway is bypassed when WSDL has SOAP and JCA binding. How to choose??
I don't know if I came across a bug, but in theory I believe this is something like this:
To indicate you want ESB binding:
<property name="preferredBindings">http://www.oracle.com/esb/</property>
To indicate you want SOAP binding (I'm not sure):
<property name="preferredBindings">http://schemas.xmlsoap.org/wsdl/soap/</property>
Please let me know about your results.
Regards.

Esb parallel processing problems with jms adapter and bpel

Hi,
I have esb project which dequeues from a jms adapter and then the esb router calls a bpel process. This bpel process takes about 10 seconds. The first step this bpel does is to return true ( to the client) to the esb router so the ESB thinks he is ready. This does not work.
Now if I use in the esb router asyn routing rule to the bpel ws then the esb dequeus all the messages from the queue. All the esb entries are green. But the esb starts one for one the bpel process and then updates the esb entry with a new start time ( very strange) .
If I use a sync routing rule then it dequeues and call the bpel process one for one.
How I can parallel proces the jms messages ,because I have 2 quad cores cpu's . Async routing rules looks like the solution.
How can the esb detects the bpel is still running even with the first action in bpel is to return true. I expected when the esb retrieves true from the bpel ws it ends the current esb entry and goes on with the next. So the total esb time takes a few seconds and not so long as the last the bpel proces finishes.
And why is he updating the starting time.
Thanks Edwin

Here is something I would like to suggest:
Can you try ESB -- (sync) --> BPEL, where BPEL process itself is Async. In that case, esb will consume all the messages very fast and BPEL will get that message and put in Delivery Queue and reply back to ESB. Now BPEL will process them simultaniously based Receiver/Worker threads defined in your env.

SQL types over PLSQL types while using Oracle Applications adapter in BPEL

Use SQL types over PL/SQL types while using Oracle Applications adapter
in BPEL/ ESB
This document will be focusing on Oracle Applications adapter. However Database adapter is much like OA adapter (even OA adapter uses DB Adapter), so the readers who are interested to explore DB adapters, can relate things with this document and go further as well.
Some Guidelines for writing PL/SQL APIs for OA Adapter
As we know when we create a partner link from the OA adapter wizard it sometimes writes some wrapper script supportive to the OA Adapter WSDL which contains below
* Object type for PL/SQL RECORD
* Nested table of the given type for PL/SQL TABLE. For example, the nested table of NUMBER.
* INTEGER substituted for PL/SQL BOOLEAN
* Wrapper Script for converting above three set of data types . (PLSQL to SQL and SQL to PLSQL conversion functions)
In runtime this wrapper script for converting PL/SQL to SQL and SQL to PL/SQL is an extra overhead.
So the first advice would be to avoid the use of the below as parameters of PLSQL API being called by OA Adapter.
* PL/SQL RECORD
* PL/SQL TABLE. For example, the nested table of NUMBER.
* PL/SQL BOOLEAN
In other way we can say we should try to use only SQL data types in arguments if we are planning to call any PL/SQL API from the OA Adapter.
If the requirement is to use a table or record uses the Object type. In place of BOOLEAN better to use VARCHAR or INTEGER what ever fulfills your requirement. Following this guideline we can reduce a huge number of Line of codes to be run each time the adapter being called.
Generally, Oracle E-Biz standard APIs use PL/SQL record types and table types so when there is a requirement to call these API’s from OA Adapter (this is a common requirement in development), and if we directly browse the API in OA Adapter Configuration Wizard and create the partner link, again a huge number of code is written by the wizard in the wrapper script (a number of extra mapping of fields which are not being used in the interface).
In this case better would be to create an Object type with only the required fields which are being used in that call and use them as parameters for the PLSQL API.

How to use Database Adapter in BPEL

I want to use Database Adapter in BPEL to transfer data from one table to other table and the data is still hold in the read table?
I can find a example from http://download.oracle.com/docs/cd/B31017_01/integrate.1013/b28994/adptr_db.htm#BDCIGDCB.
And the general design of my BPEL is as following:
1. Add a "status" column to the read table. And alter the value of status column of all data in read table to "unreaded".
2. Then create a empty BPEL (BPELAdapter) Project.
3. Add a Database Adapter:
(1) In step 1 of Adapter Configuration Wizard, configure the Service Name to datain.
(2) In step 2, configure the database connection.
(3) In step 3, choose "Poll for New or Changed Records in a Table".
(4) Then click Import Tables button, and choose the read table.
(5) In step 5, choose a column.
(6) Don’t do anything in step 6 and 7.
(7) In step 8, choose "Update a Field in the [Datain] Table (Logical Delete)".
(8) In step 9, configure Logical Delete Field to STATUS, configure Read Value to readed and configure Unread Value to unreaded.
(9) Don’t do anything in step 10 and 11.
4. Add a receive activity to connect to above database adapter.
5. Add another Database Adapter. Then configure this database adapter service WSDL:
(1) In step 1 of Adapter Configuration Wizard, configure the Service Name to dataout.
(2) In step 2, configure the database connection.
(3) In step 3, choose Perform an Operation on a Table (and all items under it).
(4) Then click Import Tables button, and choose the write table.
(5) In step 5, choose a column.
(6) Don’t do anything in step 6, 7 and 8.
6. Add a invoke activity to connect to above database adapter.
7. Add a assign activity between the receive activity and invoke activity. And configure the assign copy operation.
But after I deploy this BPEL project to the BPEL server and invoke this project, I get following error. Meanwhile, this BPEL don't take effect.
The following exception occured while processing this request:
Can't find partnerLinkType 2.
in
"file:/D:/soft/SOASuite/product/10.1.3.1/OracleAS_1/bpel/domains/default/tmp/.bpel_BPELAdapter_1.0_e82210b05e4d3e997eed581d0d220293.tmp/_BPELAdapter.wsdl" WSDL to find PartnerLinkType "{http://xmlns.oracle.com/pcbpel/adapter/db/datain/datain_plt"。
How to resolve?
Thanks,
Melody

Now, I can insert data into the table through Database Adapter.
But still can't select data from the table through Database Adapter.
Above error still happen when invoke the read database table with Database Adapter project:
Can't find partnerLinkType 2.

Error Calling BPEL from ESB

I am using the SOA Suite and have a very simple ESB project which picks up files from a directory and calls a BPEL process following a simple XSL translation. I am getting the following error:
An unhandled exception has been thrown in the ESB system. The exception reported is: "java.lang.Exception: Failed to create "ejb/collaxa/system/DeliveryBean" bean; exception reported is: "javax.naming.NamingException: Lookup error: javax.naming.AuthenticationException: Not authorized; nested exception is: javax.naming.AuthenticationException: Not authorized [Root exception is javax.naming.AuthenticationException: Not authorized] at com.evermind.server.rmi.RMIClientContext.lookup(RMIClientContext.java:64) at javax.naming.InitialContext.lookup(InitialContext.java:351) at com.oracle.bpel.client.util.BeanRegistry.lookupDeliveryBean(BeanRegistry.java:279) at com.oracle.bpel.client.delivery.DeliveryService.getDeliveryBean(DeliveryService.java:250) at com.oracle.bpel.client.delivery.DeliveryService.post(DeliveryService.java:174) at com.oracle.bpel.client.delivery.DeliveryService.post(DeliveryService.java:158) at oracle.tip.esb.server.service.impl.bpel.BPELService.processBusinessEvent(Unknown Source) at oracle.tip.esb.server.dispatch.InitialEventDispatcher.dispatchNonRoutingService(Unknown Source) at oracle.tip.esb.server.dispatch.InitialEventDispatcher.dispatch(Unknown Source) at oracle.tip.esb.server.dispatch.BusinessEvent.raise(Unknown Source) at oracle.tip.esb.utils.EventUtils.raiseBusinessEvent(Unknown Source) at oracle.tip.esb.server.service.EsbRouterSubscription.onBusinessEvent(Unknown Source) at oracle.tip.esb.server.dispatch.EventDispatcher.executeSubscription(Unknown Source) at oracle.tip.esb.server.dispatch.InitialEventDispatcher.processSubscription(Unknown Source) at oracle.tip.esb.server.dispatch.InitialEventDispatcher.processSubscriptions(Unknown Source) at oracle.tip.esb.server.dispatch.EventDispatcher.dispatchRoutingService(Unknown Source) at oracle.tip.esb.server.dispatch.InitialEventDispatcher.dispatch(Unknown Source) at oracle.tip.esb.server.dispatch.BusinessEvent.raise(Unknown Source) at oracle.tip.esb.utils.EventUtils.raiseBusiness
The esb has been deployed to our server (OAS 10.1.3) using jdeveloper. Please can anybody point me in the right direction.

Not really. There are 2 ways to invoke BPEL.
1) Over SOAP using an ESB SOAP service that parses a BPLE WSDL. This works like any standard HTTP/SOAP invocation and would be used when BPEL and ESB are not in the same container.
2) Over Java by add a routing rule to an ESB Routing Servie and select a BPEL process in the BPELSystem as the target. This is the preferred binding when ESB and BPEL are colocate din the same container. This takes advantage of the fact that ESB kistens on the BPEL internal Control jms queue when a BPEL process is deployed into the container. That is how the BPEL processes show up in the BPELSystem ESB service tree.

File Adapter vs BPEL interaction issue on high availability environment

Hi all,
i would really appreciate your help on a matter i'm facing about a composite (SCA) deployed on a clustered environment configured for high availability. To help you better understand the issue i briefly describe what my composite does. Composite's instances are started by means of an Inbound File Adapter which periodically polls a directory in order to check if any file with a well defined naming convention is available. The adapter is not meant to read the file content but only its properties. Furthermore, the adapter automatically makes a backup copy of the file and doesn't delete the file. Properties read by the adapter are provided to a BPEL process which obtains them using the various "jca.file.xyz" properties (configurable in any BPEL receive activity) and stores them in some of its process variables. How the BPEL process uses these properties is irrilevant to the issue i'd like to pose to your attention.
The just described interaction between the File Adapter and the BPEL process has always worked in other non-HA environments. The problem i'm facing is that this interaction stops to work when i deploy the composite in a clustered environment configured for high availability: the File Adapter succeeds to read the file but no BPEL process instance gets started and the composite instance gets stuck (that is, it keeps always running until you don't manually abort it!).
Interesting to say, if I put a Mediator between the File Adapter and the BPEL, the Mediator instance gets started, that is the file's properties read by the adapter are passed to the mediator, but then the composite gets stuck again 'cos even the mediator doesn't seem to be able to initiate the BPEL process instance.
I think the problem lies in the way i configured either the SOA infrastructure for HA or the File Adapter or BPEL process in my composite. To configure the adapter, i followed the instructions given here:
http://docs.oracle.com/cd/E14571_01/integration.1111/e10231/adptr_file.htm#BABCBIAH
but maybe i missed something. Instead, i didn't find anything about BPEL configuration for HA with SOA Suite 11g (all the material i found refers to SOA Suite 10g).
I've also read in some posts that for using the db as a coordinator between the file adapters deployed on the different nodes of the cluster, the db must be a RAC! Is that true or is possible to use even another type of oracle db?
Please, let me know if someone of you has already encountered (and solved :)) a problem like this!
Thanks in advance,
Bye!

Hi,
thanks for your prompt reply. Anyway, i had already read through out that documentation and tried all settings suggested in it without any luck! I'm thinking the problem could be related to the Oracle DB used in the clustered environment, which is not RAC while all documentation i read about high availability configuration always refers to a RAC db. Anyone knows if a RAC Oracle DB is strictly needed for file adapter configuration in HA cluster?
Thanks, bye!

What is the main difference between BPEL and ESB

Hi all,
I am making use ESB in my application .Where the my client application calls ESB and inturn the ESB calls the BPEL process .
I want to know the differences between BPEL and ESB,I came to know that ESB can do messaging and routing ,where my BPEL process can also do the same thing .
I came to know form a vendor that ESB is used for connecting to multiple end points ,where as my BPEL process can also do this.
SO what is main purpose of using ESB ?

Set polling time with BPEL and ESB File Adapters

We have create file adapters in BPEL and ESB. We see where you can set the frequency for polling but do not see a place to set the polling time. We would like it to check a directory every 24 hours at midnight. We can set the 24 hours but not the midnight. How does ESB and BPEL determine the time to run based upon the interval?

Oracle SOA is started, from the time the adapter is loaded, the interval counting starts. It is not on a particular time.
If you want to start a BPEL process on a certain time, you could use the quartz timer fucntionality of BPEL to start an instance on a particular time (like unix cron tab).

Deployment of BPEL (and ESB) into Clustered Environment

Hi All,
I was after any view points / pointers into peoples experiences into deployment of BPEL and ESB into a clustered Oracle iAS SOA suite environment, where there are two or more nodes running BPEL, ESB etc with a corresponding OHS Loan Balancers. I have been unable to find any specific information with regards to recommendations into the best ways to deploy into a clustered environment.
My viewpoints are there are two alternative approaches that could be used, both of which use ANT deployment scripts to register / deploy the various services.
(1) Leaving all nodes up in the cluster and using a properties file to specify the relevant details, deploy to one environment allowing the load balancer to distribute the software to the respective nodes in the cluster
(2) Deploy to each of the nodes in turn ensuring all other nodes in the cluster are taken down during each separate deployment
What are other peoples thoughts / experiences / recommendations?
Thanks in Advance
Dave

I don't believe there is any real information on deployments in a cluster in those documents.
There is a note on metalink 457654.1 which says to apply to each node, while doing this shut down the other servers. From experience this worked for some configuration and not others.
Can you say what cluster deployment you used, e.g. 10.1.3.1 or 10.1.3.3 with BPEL and ESB-RT in the same oc4j?
Also what version are you on. If you are on 10.1.3.4 using the 10.1.3.3 deployment configuration you don't need to shutdown the nodes. And you can get away with just deploying to one node but make sure your <ORACLE_HOME>/bpel/system/config/collaxa-config.xml file has been set to cluster = true. Look at metalink note 746251.1.
You can experience the notorious Process Lock Timeout Error when not shutdown cleanly but this is resolved using the best practice guide http://www.oracle.com/technology/tech/soa/soa-suite-best-practices/soa_best_practices_1013x_drop1.pdf
ESB can be applied to just one node.
Make sure that all your endpoints are pointing to the load balancer and not the actual node themselves.
Also you connect string is different in your build.properties make sure of the following
cluster = true
oc4jinstancename = default_group
local.oc4jinstancename = oc4j_soa (or the oc4j container with BPEL)
esb
deployer.uri=deployer:cluster:opmn://hostname:opmn port/default_group

BPEL and ESB in different Servers

Hi ,
What is the advantage of having BPEL PM and ESB installed in different servers ?

In my knowledge it has it own merits and demerits
IF (BPEL and ESB) installed in dfferent OC4Js (JVMs)
Merits
1) Individual JVM for each component means more memory allocation and support from JVM
2) More number of processes can be deployed.
DeMerits
1) ESB and BPEL communication can happen via SOAP over HTTP only whereas had these been deployed in the same JVM (oc4j) it can do native communication.
