JCA DB Adapter Batching
JCA DB Adapter
Table:
Coln1 - CostID (It can come any number of times, NOT UNIQUE)
Coln2 - Name
Example values
c1 - raju
c1 - rama
c2 - Rakesh
c1 - jamal
I have a select query in DB Adapter - get distinct values of CostID - from above table.. There are around 50000+ records.
Do we have any batching concept here to read 1000 records at a time and process? In inbound adapter , i hope we can use batching (maxTransactionSize,maxRaiseSize), but for synch read of DBAdapter how can we acheive this..
Regards

Hi Sesha,
There is nothing that I'm aware of... If you are not using polling, where you have maxTransactionSize,maxRaiseSize... Then all you have is the where clause...
You can work with the where clause and the ROWNUM pseudo column (Oracle)...
SELECT * FROM employees WHERE ROWNUM < 11 ORDER BY last_name;

I need Fusion help creating a demo of BRM JCA Resource Adapter
I need Fusion help creating a demo of BRM JCA Resource Adapter.
I know BRM well but am clueless with Fusion.
I am trying to figure out what Fusion products to download and install and how I manipulate the Fusion side to manipulate BRM.

Deploying the BRM JCA Resource Adapter on an Oracle application server
The adapter is dependent on Java Archive (JAR) files to deploy properly. The following table lists the JAR files that the adapter requires from each application in your system.
Application
JAR files
J2EE application server
classes12.jar, connector15.jar, and jta.jar
Oracle BPEL process
bpm-infra.jar, orabpel-thirdparty.jar, orabpel.jar, and xmlparserv2.jar
BRM J2EE Resource Adapter
pcm.jar and pcmext.jar
Apache
xercesImpl.jar
If you are deploying the adapter in a standalone Oracle Containers for Java EE (OC4J) instance, make sure these JAR files are available to the class loader that is loading the adapter.
If you are deploying the adapter by using Oracle SOA Suite, these JAR files are available as part of the oracle.bpel.common code source. You import these libraries as follows:
Open the Oracle_home/j2ee/Instance/config/applications.xml configuration file for the J2EE instance.
Add the oracle.bpel.common entry (shown in bold below) to the imported-shared-libraries section of the file:
<imported-shared-libraries>
<import-shared-library name="adf.oracle.domain"/>
<import-shared-library name="oracle.bpel.common"/>
</imported-shared-libraries>
Save and close the file.
Restart the application server or the J2EE instance.
After you make the JAR files available, deploy the adapter on the Oracle application server by using either the Oracle Application Server (Oracle AS) Application Server Control (ASC) or the Oracle admintool.jar file. Copy the adapter archive file (BRM_home/apps/brm_integrations/jca_adapter/OracleBRMJCA15Adapter.rar) from the installation directory to a location that is accessible to the adapter deployment tool. You can then open and deploy the archive file on your application server.
After successful deployment, return the applications.xml file to its original settings and add the oracle.bpel.common codesource to the BRM Adapter oc4j-ra.xml file:
Open the Oracle_home/j2ee/Instance/config/applications.xml configuration file for the J2EE instance.
Remove the following oracle.bpel.common entry (shown in bold below):
<imported-shared-libraries>
<import-shared-library name="adf.oracle.domain"/>
<import-shared-library name="oracle.bpel.common"/>
</imported-shared-libraries>
Save and close the file.
Open the JCA Resource Adapter oc4j-ra.xml file from the Oracle_home/j2ee/Instance/application-deployments/default/BRMAdapterDeploymentName directory.
Add the oracle.bpel.common entry (shown in bold below) to the oc4j-connector-factories section of the file:
<oc4j-connector-factories...>
<imported-shared-libraries>
<import-shared-library name="oracle.bpel.common"/>
</imported-shared-libraries>
<oc4j-connector-factories>
Save and close the file.
Restart the application server or the J2EE instance.
For more information about deploying the adapter, see your application server’s documentation.
Connecting the adapter to BRM in Oracle AS
You connect the adapter to the BRM software by creating connection pools and connection factories. As part of the adapter deployment, the application server creates oc4j-ra.xml from the packaged ra.xml. The ra.xml file is located in the Oracle_home/j2ee/Instance/connectors/AdapterDeploymentName/AdapterDeploymentName/META-INF directory. For example, Oracle_home/j2ee/home/connectors/BRMAdapter/BRMAdapter/META-INF/ra.xml.
Use the resource adapter home page from the Oracle AS ASC page to create connection pools and connection factories.
Create your connection pool by following the performance and tuning guidelines in Configuring Connection Pooling in OC4J in Oracle Containers for J2EE Resource Adapter Administrator's Guide. See download.oracle.com/docs/cd/B31017_01/web.1013/b28956/conncont.htm.
Make sure you set the pool’s Maximum Connections parameter (maxConnections XML entity) equal to or greater than the Oracle BPEL process manager’s dspMaxThreads parameter. For more information, see Oracle BPEL Process Manager Performance Tuning in Oracle Application Server Performance Guide for 10g Release 3 (10.1.3.1.0) at download.oracle.com/docs/cd/B31017_01/core.1013/b28942/tuning_bpel.htm.
Note To set up JCA Resource Adapter transaction management in BPEL, you must create a private connection pool and set its Inactive Connection Timeout property (inactivity-timeout XML entity) to 0. See About JCA Resource Adapter transaction management in BPEL for more information.
Create as many connection factories as your system needs. For each connection factory, specify the following:
The JNDI location for the connection factory.

OSB Error in deploying a project with jca file adapter
Hi,
I am facing an issue where I am getting an error when deploying a service from Eclipse. I am using OSB/SOA 11.1.1.5 2 node cluster. I have an OSB service where I am writing to a file and am using file adapater. I created a composite with file adapter to write a file then imported .jac, .wsdl and composite into eclipse and generated a business service out of .jca file. When I deploy the project from eclipse I am getting the below error and am not able to deploy the project.
Conflicts found during publish.
Invalid JCA transport endpoint configuration, exception: javax.resource.ResourceException: Cannot locate Java class oracle.tip.adapter.file.outbound.FileInteractionSpec
Cannot locate Java class oracle.tip.adapter.file.outbound.FileInteractionSpec
I have FileAdapter deployed and pointed to OSB manage servers cluster. Here is a snippet of config.xml.
<app-deployment>
<name>FileAdapter</name>
<target>SOA_Cluster,OSB_Cluster</target>
<module-type>rar</module-type>
<source-path>/app/oracle/fmw/Oracle_SOA1/soa/connectors/FileAdapter.rar</source-path>

<security-dd-model>DDOnly</security-dd-model>
<staging-mode>nostage</staging-mode>
</app-deployment>
Also inside console -> deployments -> FileAdapter -> Targets and OSB_Cluster is checked also.
Here is the .jca file
<adapter-config name="writeFile" adapter="File Adapter" wsdlLocation="writeFile.wsdl" xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
<connection-factory location="eis/HAFileAdapter"/>

<property name="Append" value="false"/>
<property name="FileNamingConvention" value="a_%SEQ%.doc"/>
<property name="NumberMessages" value="1"/>
</interaction-spec>
</endpoint-interaction>
</adapter-config>
Any idea what might be wrong.
Thanks.I already have the fileAdapter JNDI is already configured in console. The error I am getting is during the deployment

Error getting VARCHAR2 in an object using JCA DB Adapter.
I am facing a problem with the JCA db Adapter and i am not able to solve.
I have created an Oracle Object like:
CREATE OR REPLACE TYPE FACTURAE AS OBJECT
( MODALIDAD VARCHAR2(1),--I
TipoEmisorfactura VARCHAR2(2),--EM
Then i have created a procedure which returns the mentioned type;
FUNCTION FUsorgen_obtenerdatosFactura (IDFACTURA IN NUMBER,strTipoFactura IN VARCHAR2)RETURN FACTURAE
IS
Then i have created a JCA db Adapter in Jdeveloper obtaining an wsdl and a xsd schema. Both files are valid
Finally i have created a business service based on this wsdl. When i have tested this y get an xml like:
<OutputParams>
<MODALIDAD>???</MODALIDAD>
<TipoEmisorfactura>12</TipoEmisorfactura>
</OutputParams>
I have checked that executing the procedure with the same parameters the field "MODALIDAD" has value "I" so it is not null nor "???".
Have anybody an idea what is happening? Is there a known bug with personaliced objects and DB Adapter?
Best Regards.Perhaps you could post your XSD and the instance XML that you provide for the input parameters.
The generated XML for the output parameters should look something like the following.
<OutputParameters ...>
<FUsorgen_obtenerdatosFactura>
<MODALIDAD> ... </MODALIDAD>
<TipoEmisorfactura> ... </TipoEmisorfactura>
</FUsorgen_obtenerdatosFactura>
</OutputParameters>Notice that the function name is the name of pseudo-parameter encapsulating the attributes of your object type. -

Hi,
I have requirement to move files between two ftp servers. I have implemented this using OSB services configured with jca ftp adapter. After reading the files from the source system the adapter is configured to delete the file from source directory. While moving the files if the target system is unreachable the transaction should roll back and the file should remain in the source directory.
Can this be achievable using jca ftp adapter. Does ftp adapter have XA capability?
Thanks,
Sai.OSB's ftp transport is transactional on the inbound side ( proxy service side) .. So you could use this.. Make sure you are not configuring any reply actions in any of the error handlers.. When route error occurs make sure the error is allowed to propagate back to the system error handler.. .
By default osb's ftp transport will retry only once and then move the file to the error directory. If you want to change this behaviour say retry infinitely or retry after a delay , you have to change the dleivery failure settings for the internal JMS queue WLSAdmin Console --> JMSModules --> jmsResources --> wlsb.internal.transport.task.queue.ftp_auto_2 ( wlsb.internal.transport.task.queue.ftp_auto_3 and so on) Delivery Failure and change redelivery delay and redelivery limit.
Note OSB's ftp transport is not transactional outbound(business service) , so you might get only "At-least once" (and not "exactly-once") quality of service using this .. -
JCA Polling Adapter not picking up records
Hello All
I have been trying to configure a JCA polling adapter to pick up records from the Database, the first time I configured it, it read a whole bunch of records. Now I have configured the following in the database and am getting no records being polling.
1. Poll for new or changed records
2. Update a field in the table F40g02 for logical delete
3. Read value = READ, UNREAD value = UNREAD, Reserved value = RESERVED
4.Polling interval 5 seconds, Database XROWS per xml document 1, Database Rows per Transaction 10
I ran the SQL specified in the adapter and I get a record. Does anyone have any idea.
I have seen this warning in the EM
Database Adapter <oracle.tip.adapter.db.inbound.IPAddrPollingService getUniqueMarkReservedValue> The markReservedValue of distributed polling might not be a unique value. To make it so, you can add the last x digits (default = 2) of the host IP address using this format for the MarkReservedValue: [original_val]${IP[-x]}
RegardsHello
The problem I am facing is I can't get the records that are processed (already READ) to not poll again despite the value being changed to the READ value configured, if I set the READ value in the configuration it will poll every record all the time despite the fact it is equal to the READ value. Then if I set the READ value and any other value no records will poll.
Consider 4 records in the DB (currently in test I have 431 but I have used distributed locking and ReturnSingleResultSet to limit it)
ID = 1, STATUS = PROCESSED
ID = 2, STATUS = UNPROCESSED
ID = 3, STATUS = UNPROCESSED
ID = 4, STATUS = OTHER
Config 1: If READ = PROCESSED records 1,2,3,4 will poll
Config 2: If READ = PROCESSED, UNREAD = UNPROCESSED no records will poll
Config 3: If READ = PROCESSED, UNREAD = UNPROCESSED, RESERVED = OTHER no records will poll
Config 4: If READ = PROCESSED and TOPLINK STATUS not equal string "PROCESSED" then records 1,2,3,4 will poll
What I want is Record 2 and 3 to poll which I believe is config 3 should do. However I believe there have been some changes that relate to distributed polling for clusters in 11.1.1.3 onwards which means in jdeveloper (11.1.1.6) when I go to re-config the db adapter after setting the RESERVED value it disappears from the editor .
JCA properties obviously with a MarkReservedValueand MarkUnreadValue column jumping in.depending on which config I am trying
<property name="DescriptorName" value="dbPollBlockRecords.F40G02"/>
<property name="QueryName" value="dbPollBlockRecordsSelect"/>
<property name="MappingsMetaDataURL" value="dbPollBlockRecords-or-mappings.xml"/>
<property name="PollingStrategy" value="LogicalDeletePollingStrategy"/>
<property name="MarkReadColumn" value="STATUS"/>
<property name="MarkReadValue" value="PROCESSED"/>
<property name="PollingInterval" value="700"/>
<property name="MaxRaiseSize" value="1"/>
<property name="MaxTransactionSize" value="10"/>
<property name="NumberOfThreads" value="1"/>
<property name="ReturnSingleResultSet" value="true"/> (This property has been manually configured, will unfortunately poll all records that match without it)

How can I extend the JCA File Adapter
I would like to extend the JCA File adapter. I want to overcome the file size limit of the File Adapter.
I want to the JCA Fileadapter to have the following functionalites.
1. Split a file into smaller chunks, The chunk size will be set at design time and will be in bytes, an example would be split the file into 500K chunks.
2. Each file chunk will contain a Correlation Identifier and Message Sequence identification fields so it can be rebuilt by the receiver.
Is the beat approach is to write my own JCA File Adapter if I do how do I incorporate it within Jdeveloper?In short, you will have to do the following:
1. Develop an adapter which is compliant to JCA 1.5 spec. You should be able to run that as a web application within the OAS.
2. It should create a WSDL which is adhering to the WSDL Spec 1.1. Then JDeveloper will consume the same without any issues during the design time.
Alternately,
You can check with Oracle with the new featuren requrest for enhancing the File adapter. -
Hi everybody,

I am just testing one simple SOA Application in SOA 11g Suite. Created a SOA Composite Application with one DB Adapter at designtime all worked fine with DB Adapter. But when I deploy the Application on the server I get the following error:
The JCA Binding Component was unable to establish an outbound JCA CCI connection due to the following issue: BINDING.JCA-12510 JCA Resource Adapter location error. Unable to locate the JCA Resource Adapter via .jca binding file element <connection-factory/> The JCA Binding Component is unable to startup the Resource Adapter specified in the <connection-factory/> element: location='eis/DB/soademoDatabase'. The reason for this is most likely that either 1) the Resource Adapters RAR file has not been deployed successfully to the WebLogic Application server or 2) the '<jndi-name>' element in weblogic-ra.xml has not been set to eis/DB/soademoDatabase. In the last case you will have to add a new WebLogic JCA connection factory (deploy a RAR). Please correct this and then restart the Application Server ".Do I need to jndi-name in weblogic-ra.xml if so what is the exact location. Any help is appreciated.
ThanksI did but still not able to connect now getting the following error. I went to the Weblogic Console, clicked on deployments, selected DBAdapter, clicked on configuration ,
and then I don't see outbound configurations instead it shows Outbound Connection Pools, Under Outbound Connection Pools tab I clicked on New and it asked to select Outbound Connection Group I selected the one that was already there (with JNDI eis/DB/SOADemo) and then created my JNDI which was added to the default Outbound Connection Group and in the end it asked to save the Plan.xml which I saved it under a new directory created under soa directory. But still am not able to connect.
How do I create my own Connection Group as don't want to use the defualt one out there.
After creating the JNDI Name it asks for saving the Plan.xml file. Where exactly we save this file. Are there any standards.
Why can't I update any properties when I click on the new JNDI name it takes to Settings for javax.resource.cci.ConnectionFactory --> Outbound Connection Properties but there I see a save buttn but I can't make any changes.
BINDING.JCA-12563 Exception occured when binding was invoked. Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'getCreditValidationSelect' failed due to: Could not create/access the TopLink Session. This session is used to connect to the datastore. Caused by javax.resource.spi.InvalidPropertyException: Missing Property Exception. Missing Property: [DBManagedConnectionFactory.userName]. You may have set a property (in _db.jca) which requires another property to be set also. Make sure the property is set in the interaction (activation) spec by editing its definition in _db.jca. . ". The invoked JCA adapter raised a resource exception. Please examine the above error message carefully to determine a resolution. Is there any documentation that lists all these steps as I couldn't find it anywhere. The guide only talks abou DBAdapter but how to configure etc can't find any info. Any help is appreciated.

Problem with PCK 7.1 SP07 JCA Sample Adapter
Hello!
I have a Problem with the JCA Sample Adapter in the PCK 7.1 SP07. I will test the Configuration ( http://help.sap.com/saphelp_nwpi71/helpdata/en/f7/0c2441509fa831e10000000a1550b0/content.htm ) .
But the receiver channel has a Massage processing failure: u201CMessage processing failed. Cause: java.lang.Exception: JNDI name of the ra connectionFactory is not configured. Go to the directory and create a value with name 'JNDIName' and value 'deployedAdapters/<ra name>/shareable/<ra name>' as module configuration data of the module 'ModuleProcessorExitBean'u201D
In the JNDI-Browser of Netwaver Administration canu2019t found JNDIName from directory ('deployedAdapters/sample_ra/shareable/sample_ra). I have located the name deployedAdapters/com.sap.aii.adapter.sample.ra/shareable/com.sap.aii.adapter.sample.ra and change this in the receiver channel u201CTo_Au201D. But I have the same problem.
I hope you can help me!
Thanks & Regards
StefanHello!
Yes I followed the Instruction.
I have deployed the Sample Source as AdapterJCA, change the JNDI name in the SampleRa.xml and upload to CPA Cache.
I have by now the Configuration deleted in PCK and rebuild the scenario. The demo Configuration runs now. I think the Configuration in the CPA Cache was wrong.

Singleton JCA DB Adapter in OSB
Hi,
I am planning to use the JCA DB Adapter for polling insert/update events in a database in OSB 11g. Basically I am creating the jca adapter in JDeveloper, then generate the proxy service from OEP Eclipse and import the project into OSB. The Proxy is working fine by polling the events, but it needs to run in cluster and so I want to know how to make the adapter as a singleton ?
Any thoughts are really appreciated.
Thanks!aren't the default cluster aware settings enough for this ?

Setting up JDBC Data Source for JCA Database Adapter in WLS - only SID?
Following the documentation for setting up a connection for use with the JCA Database Adapter (http://otnbeta.oracle.com/fmw11g/582tj30eapvb/integration.1111/e10231/life_cycle.htm), section 2.4.1, Step 8 simply says "Enter the connection properties in the Connection Properties page, and then click Next"
In the "Create a New JDBC Data Source" screen of the WLS Administration Console there is the entry field vaguely labeled as "Database Name:" Of course I entered the Oracle RDBMS service name (which we should ALWAYS be using), only to be informed upon clicking next, that WLS was expecting the SID.
Two things:
1. At least through this maintenance console, it appears that BEA did not understand the whole concept or value of Oracle RDBMS logical service names versus the SID (I have seen this in several products that Oracle has acquired). Best practice would be to use the Oracle RDBMS service name, which doesn't appear to be an option in this console.
2. The OFM documentation should be more helpful in explaining.Compare to the analogous setup in OAS 10.1.3.4/EM... far better clarity in the maintenance console and option of either SID or service name.

Customizing JCA FTP Adapter properties in OSB
Hi,
I have requirement to read a file from one file system and write it on another file system.I have implemented this using jca FTP adapter in OSB.
The read and write directory will be different across environments in which I need to deploy the project.
The read and write directory info is present in the jca file as given below.
<activation-spec className="oracle.tip.adapter.ftp.inbound.FTPActivationSpec">
<property name="DeleteFile" value="true"/>
<property name="MinimumAge" value="0"/>
<property name="PhysicalDirectory" value="TEST/INPUT"/>
<property name="Recursive" value="true"/>
<property name="PollingFrequency" value="10"/>
<property name="FileType" value="ascii"/>
<property name="PhysicalArchiveDirectory" value="/PROJ/ARCHIVE"/>
<property name="IncludeFiles" value=".*\..*"/>
<property name="UseHeaders" value="false"/>
</activation-spec>
Is it possibel to cahnge this valueof <property name="PhysicalDirectory" value="TEST/INPUT"/> using customization files. From the OSB docs I undersatnd that only OSB predefined environment values can be changed using customization files.
Thanks,
Sai.Hi Prabu,
The directory name is not appearing in the configuration of the services.
I have specific reason for going with jca Adapter. Why writing the files to the destination if some failure happens ftp protocol may cause partially written files but I think JCA adapter will make sure either the file is completely transferred or not transferred at all.
If this cannot be done in OSB I think I need to go for BPEL implementation where the config plan supports the replacement of JCA properties.
Thanks,

JCA Resource Adapter Deployment in OAS 10.1.2
Hi,
I have installed the Oracle Application Server 10g Release 2 (10.1.2) (j2ee & web cache) and I want to know how I can deploy a JCA Resource Adapter. Until now I have work with Oracle Application Server 10g Release 3 (10.1.3.1.0) and this version has a section in the administration web (applications->Standalone Resource Adapters) where I can deploy the RA.
But now, I have to deploy a Resource adapter in OAS 10.1.2 and I don't know how to do it. Any help?
Thanks,
MiquelIs there any error or warning message in WLS server log related to your adapter? WLS may ignore some properties if found non-fundamental error.
