OSB Db Adapter on Cluster

HI All,
We have PS with DB adapter that polls for a data which is deployed on OSB domain A with 8 manage servers in cluster.
We too have OSB domain B with 8 manage servers in cluster and same service deployed.Can we enable the same PS on Domain B or it will run into locking of the table issue.
Thanks
Amar

You can pass in the adapter header property "jca.db.ProxyUserName". That way you can specify a user for each invoke.
I got confirmation that OSB supports setting these properties. The sample adapters-db-201-MovieImages on soasamples.samplecode.oracle.com > Adapters shows working with header properties but with Mediator.
Thanks

How OSB AQ adapter dequeue from database AQ ?

Hi,
Could someone please tell me how OSB AQ adapter dequeues from database AQ ?
Does it ask database frequently ? Or just hangs on database ?
Or database AQ notifies OSB when something comes to AQ ?
Regards,
Cezary

I don't have any experience with AQ adapter for OSB, but when I was working with AQ library for JMS I had the same question and found out that it was polling the database.

OSB db-adapter: how to pass a proxy user or something like this?

Hello, on OSB with a Oracle db-adapter, I'd like to do some database updates. Usually the db-adapter is set up with a technical database user.
But on database side, this way I don't know exactly which user has been updating my table because only the technical user will be inserted into "Created_by" Column
(select USER from dual ==> technical user).
Now I thougt about using Proxy Users. But there exists some other Problems:
- every proxy user has to be initially created in the database
- how can I pass proxy user and technical user from OSB to the database?
(using JCA, JNDI and JDBC Data Sources)
... on JDBC datasources I can only specify hard coded userid/password (--> technical user)
Any help would be appreciated. Maybe some good white papers or tutorial exists in the web, but I can't finde a good one.
Thanks

OSB DB Adapter Polling Issue

Hello Everybody,
Requirement
I am doing DB Adapter polling in OSB.I have a db adapter which polls order table whenever there is a record with status='N'.The OSB component is on single node of Weblogic Server.
1.The db adapter picks the order data with status='N' in the proxy service
2.It transforms to webservice xsd
3.Invokes a webservice.
4.The webservice returns acknowledgement number.
5.The order table should be updated with status 'Z' and attribute1=acknowledgement number
OSB Service Design
1.Proxy service calls business service to poll the order table
2.Converts the payload to the xsd format required by target
3.Invokes the webservice on target
4.Receives acknowledgement number
5.calls a plsql procedure which updates all the records within this batch with the acknowledgement number and status='Z'
My configurations in db adapter
Logical delete option in db adapter.
Unread Value :'N'
Read Value : 'A'
Polling frequency : 300 seconds
no of databse rows per XML document : 10
Database rows per transaction : 10
Issue
1.My process after getting the acknowledgement number it updates the status with Z and attribute1=acknowledgement number.At the of this transaction I am seeing that the status is being updated by
the adapter to 'A' based on read value.I want the read value only to be updated initially but as soon as my OSB process picks it for further processing it should not update again.How can i prevent
the status from getting updated to 'A'.
2.I have 40 records in order table.Per the database rows per transaction it should process 10 records at a time and for each batch of 10 i should get one acknowledgement number.Instead i see that
all the 40 records are updated with the same acknowledgement number.Kindly help as to how I can resolve this situation.
Thanks & Regards,
Radha

Hi Arik,

Osb jca adapter weird behaviour

Hi gurus,
Im running OSB 11.1.1.5 having a db adapter polling an MSSQL2000 table (SELECT WITH (UPDLOCK, NOWAIT)..)
The table is being filled by a long running transaction.
I observe in the JCA logging the following error on every polling iteration while the table is being filled:
<Jan 10, 2012 2:00:45 PM CET> <Error> <JCA_FRAMEWORK_AND_ADAPTER> <BEA-000000> <<oracle.tip.adapter.db.InboundWork handleException> Encountered a fatal exception while polling. Will continue polling but with minimal logging. Please investigate the fault and manually stop polling from the console if in development and this appears to be a modeling mistake. BINDING.JCA-11624
DBActivationSpec Polling Exception.
Query name: [O_Boeking_I_PollerSelect], Descriptor name: [O_Boeking_I_Poller.OBoeking]. Polling the database for events failed on this iteration.
Caused by java.sql.SQLException: [FMWGEN][SQLServer JDBC Driver][SQLServer]Lock request time out period exceeded..
This exception is considered not retriable, likely due to a modelling mistake. To classify it as retriable instead add property nonRetriableErrorCodes with value "-1222" to your deployment descriptor (i.e. weblogic-ra.xml). This polling process will shut down, unless the fault is related to processing a particular row, in which case polling will continue but the row will be rejected (faulted).
The issue I'm experiencing occurs after the long running transaction is done. What I see is that in the next polling sweep 2 XML documents are delivered by the db adapter engine...I cannot figure out why. I do not want this
1 document contains only 1 record. The other document contains the rest of my records.
Have tried both WebLogic and MS JDBC drivers.
Some of mine properties:
MaxRaiseSize = 0 (I want all the records in 1 XML document)
MaxTransactionSize = unlimited
Thanks alot

Veejay,
Have done so...I tried some different setting like test-connections-on-reserve (was off)...no successes here.
I will give a try with another mssql driver version.
Another interesting thing I have observed is when I do not commit the long running transaction, the next db adapter polling event results in this exception:
<Jan 17, 2012 12:24:10 PM CET> <Error> <JCA_FRAMEWORK_AND_ADAPTER> <BEA-000000> <<oracle.tip.adapter.db.InboundWork handleException>

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://victor-jan.blogspot.com.au/2012/06/osb-fn-beaexecute-sql-vs-jca-dbadapter.html
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...
Hope this helps...

WLS/OSB DB Adapter - JNDI lookup failed

Hello all.
I've got a DB adapter service set up in a clustered environment, and it all works (and I've built proxy services, transformations etc around it), but I've just noticed that the log shows a warning regarding the JNDI lookup of the ConnectionFactory, as below.
It's working, and the error is only a warning, but could this cause problems going forward, particularly with regards performance?
Given that the ConnectionFactory name is 'com.whatever.myServiceDB', and the Endpoint URI of the service is 'jca://com.whatever.myServiceDB', what could be wrong? Has anyone seen/fixed this before? It's almost like the managed servers don't know about the JNDI name...but the DbAdapter deployent has 'All servers in the cluster' selected in its 'Targets' tab, so I'm not sure.
Any pointers would be appreciated, I'm probably missing something obvious.
Cheers.
####<Apr 15, 2010 10:53:10 AM BST> <Warning> <JCA_FRAMEWORK_AND_ADAPTER> <servername> <managed3_domainname> <[ACTIVE] ExecuteThread: '4' for queue: 'weblogic.kernel.Default (self-tuning)'> <<anonymous>> <> <> <1271325190453> <BEA-000000> <servicebus:/WSDL/MyProject/MyService [ MyService_ptt::merge(MessagesCollection) ] - JNDI lookup of 'com.whatever.myServiceDB' failed due to: String index out of range: -1>

Thanks again.
In case anyone runs into a similar problem and is wondering: a bit of mucking about reveals that the WLS ConnectionFactory config is fine with dots or slashes, and it seems to treat both the same when creating the JNDI tree.
However, the WSDL (that you probably created in JDeveloper) has to have slashes for doing its lookup. So, for example, always use slashes rather than dots when setting your DB Adapter JNDI name in JDeveloper. I guess this is a bit different from usual class/package naming standards, so may catch someone else out too.
Cheers.

OSB DB-Adapter and a date column: JCA exception ISO 8601 date format?

Hello
I work with Oracle Service Bus (eclipse oepe and jdev)
On database side I've a view with a date column (datatype=date!)
With JDev I create a DB Adapter with a select operation on that view. This db adapter can be successfully generated.
Now I import the generated artefacts (xsd, wsdl, jca) into my eclipse service-bus-project. Then I generate a business service based on the jca. Also this works fine.
Then I deploy the project to my developement osb. Also this works fine.
When I test my business service (osb test console), I get a runtime error:
Exception: com.bea.wli.sb.transports.jca.JCATransportException: oracle.tip.adapter.sa.api.JCABindingException:
Exception Description: The object [03.07.70], of class [class java.lang.String], from mapping [org.eclipse.persistence.mappings.DirectToFieldMapping[geburtsdatum-->XYZ_VIW.GEBURTSDATUM]] with descriptor [ObjectRelationalDataTypeDescriptor(DB_Adabper_XZY.XZY--> [DatabaseTable(XYZ_XYZ_VIE)])], could not be converted to [class java.sql.Timestamp].
Zeichenfolgenwert im XML-Code kann nicht in java.sql.Date konvertiert werden.
Datenbanken akzeptieren zwar Zeichenfolgen, die Datumsangaben in verschiedenen Formaten darstellen, jedoch akzeptiert der Adapter nur Zeichenfolgen, die Datumsangaben im ISO-XML-Datumsformat darstellen.
Der Eingabewert muss das ISO 8601-Datumsformat YYYY-MM-DD aufweisen.
==> so this seems to be a date format problem. but why?
I've checked the view ---> it's a date!
After that I do not have any influence to change it - and actually I don't want to change it. It still should be a datatype of DATE.
Why does JDEV not correctly convert it?
Anyone had the same problem?
Any help would be appreciated.
Thanks
Best regards,

OS is winXP
database is Oracle9i Enterprise Edition Release 9.2.0.8.0 - 64bit Production
Yes it is a datetime:
<xs:element name="geburtsdatum" type="xs:dateTime" minOccurs="0" nillable="true"/>
This is absolutelly correct. But on runtime, I'll get the date convertion error as mentionend above. It seems as the date cannot be converted from database date column to a osb date.
Strange, I didn't expect to have date format problems here.
I use
1.) Oracle Database (view) with a DATE column
2.) Oracle JDeveloper database adapter (generated db adapter based on view, point 1)
3.) Oracle Service Bus using the jca of generated database adapter, point 2)
So I think I don't have to set any date format, everything shoult be a DATE and therefore no formating has to be done by me, or am I wrong?
Best regards

OSB DB Adapter Response

Hi,
I created an OSB with DB Adapter, i was able to insert and update in the table I created, however, when an error is encountered, I want to display the oracle db error message returned. The only message being returned by the OSB Business Service is "The invocation resulted in an error: Invoke JCA outbound service failed with application error." Is there a way to return the oracle DB error message?
Thanks..

Yes, you need the patch. You can download it from My Oracle Support (https://support.oracle.com) if you have paid for Oracle Support. After applying the patch, detailed error information (including SQL error) will be returned by Business Service.

OSB JCA Adapter - Enqueue - BLOB Oracle data type

Hi,
I am tring to enqueue a message into oracle advacned queue using JCA AQ adapter of OSB. The message in the Q has BLOB data type.
I used AQ Adapter enqueue operation for this, and an opaqueue schema in the adapter wsdl. I created a business service out of the adapter service and tested it using
OSB. I am able to enqueue, but then if i go and see in the data base payload the value of the BLOB column is JUNK... some funky values..
Any help on this. Appreciate your suggestions.

Validation of SOA Suite / OSB / SAP Adapter install

We will be doing a clustered install of SOA Suite 11g, OSB and the SAP Adapter at a customer next week.
I was wondering if anyone has any validation scripts/tests that I might use to test basic functionality and connectivity after the install.
When we deployed into DEV (a single node) environment, we wrote a simple HelloWorld test. I thought I'd check here to see if anyone has something they use to validate their installs.
We will be installing SOA Suite 11gPS2, OSB 11g and the SAP Adapter (PS1) into SOA Suite. The OS is RedHat Linux 5.5.
If there is a better place for me to ask this question, please direct me there.
Thanks,

Is there any problem because of which the thread is getting stuck. Is there any parameter for the DB adapter which can be changed to fix this problem.

OSB: DB Adapter use

Hi
I need to use multiple tables in DB (10-12 tables, not all identified yet) for DB processing. All those tables reside in one DB.
My idea is not to write a procedure but create business services for them and orchestrate for processing. I wish to use default provided QueryByExample, Insert and Update operations for each service.
As of now, when I use JDeveloper, essentially one business service with three operations (QueryByExample, Insert and Update) is created for one table. So I have 10 business services, each with three operations.
I was wondering if rather than having 10 business services, can I have three services with 10 operations each? Like:
BS_QueryByExample : (QueryByExample for TABLE_1, TABLE_2......TABLE_10)
BS_Insert : (Insert for TABLE_1, TABLE_2......TABLE_10)
BS_Update: (Update for TABLE_1, TABLE_2......TABLE_10)
Is there a way to generate code through DBAdapter wizard in JDeveloper as above?
OR
If not can you suggest me another way?
Thanks and Regards,

OSB: cluster creation script fails to delete migratable targets

Hi,
I am working on a wslt script which creates an OSB domain with a cluster with one admin server and two managed servers. In this script, after adding the OSB required templates, I would like to delete the migratable targets created by the template. I do this like this:
cut
def deleteResources(mbeanType):
     log ('Deleting resources of type %s' % mbeanType)
     cd('/')
     mbeans = get(mbeanType+'s')
     for mbean in mbeans:
          log ('\tDeleting %s' % mbean.name)
          cd('/')
          delete(mbean.name, mbeanType)
def deleteTemplateGeneratedResources():
     deleteResources('JMSServer')
     deleteResources('SAFAgent')
     deleteResources('FileStore')
     deleteResources('JMSSystemResource')
     deleteResources('JDBCSystemResource')
     deleteResources('MigratableTarget')
deleteTemplateGeneratedResources()
cut
This goes through but when I save the domain (updateDomain()) the migratable targets still exist! I tried it manually on this domain after I do the delete() the migratable targets disapper (ls('/MigratableTarget') fails saying there is no MigratableTarget). However, after I do an updateDomain() the migratable targets remain. How can I get rid of them? Why don't they get removed?
Regards
Dimo

I tried deleting and creating them anew but it then messes up the configuration of the migratable targets. What seems to work now is to delete them, create new ones with DIFFERENT names and then updateDomain(). In this case the old ones get really deleted. Really messy stuff.

What is the best practice to perform DB Backup on Sun Cluster using OSB

I have a query on OSB 10.4.
I want to configure OSB 10.4 on 2 Node Sun Cluster where the oracle database is running.
When im performing DB backup, my DB backup job should not get failed if my node1 fails. What is the best practice to achieve this?

Hi,
Each Host that participates in an OSB administrative domain must also have some pre-configured way to resolve a host name to an IP address.Use DNS, NIS etc to do this.
Specify cluster IP in OSB, so that OSB always looks for Cluster IP only instead of physical IPs of each node.
Explanation :
If it is 2-Node OR 4-Node, when Cluster software installed in these nodes we have to configure Cluster IP so that when one node fails Cluster IP will automatically move to the another node.
This cluster IP we have to specify whether it is RMAN backup or Application JDBC connection. Failing to second node/another Node is the job of Cluster IP. So wherever we install cluster configuration we have to specify in all the failover places specify CLUSTER IP.
Hope it helps..
Thanks

Osb cluster- HTTP proxy service 404 error

Hi All,
I have a cluster set up with 2 managed servers. I crated a Any SOAP proxy from sbconsole to test If I can reach managed server form an external service. I do not have front load balancer set yet.
osb server1: rdoelapp001011:61703
osb:server2:rdoelapp001013:61703
admin server : rdoelapp001011:61701
when I am trying to access http proxy using any of osb server host and port I am getting 404 error ( From the admin console I could see all the servers are running)
surprisingly I am getting success (200) when I am using admin server host and port.
That means the proxy is not got deployed to the managed server, it deployed to admin server
I looked into few weblogic/OSB document, I could not see anything specific regarding deploying HTTP proxy to osb servers in a cluster
How would I make sure to deploy to the cluster not to admin server
I also tried creating a file poller proxy to see if I get "Managed server" option to set. But I do not see that option here.
Any help will be greatly appreciated.
Edited by: 818591 on Feb 21, 2011 8:52 PM

According to your suggestion, I created a domain from scratch using config wizard with a cluster with two managed server
I started admin server then started managed server
I do not have any JMS stuff created/configured yet
while starting up managed OSB server I am getting below error. I think it is related JMS reporting stuff. In my scenario we do not need any reporting feature.
How would I disable it? while creating domain I did not select the ckeckbox for reporting. Then where did it come from?
Please suggest.
