The cause of this exception is the Environment variables are not set properly.

Solution:

We have followed the following steps to resolve the issue (the steps are specified in the metalink note 1399244.1).

Following Environment variables should be set for Solaris in the .profile file:
  • Set ORACLE_COMMON_HOME   ORACLE_COMMON_HOME=$MWHOME/oracle_common;export ORACLE_COMMON_HOME
  • Set LD_LIBRARY_PATH to
           $ORACLE_HOME/lib32
  • Set LD_LIBRARY_PATH_64 to
          $ORACLE_HOME/lib
  • Ensure that PATH has reference to
         $ORACLE_COMMON_HOME/common/bin
        $ORACLE_COMMON_HOME/bin
  • set CLASSPATH to include this:
            $ORACLE_HOME/lib:$MW_HOME/jdk1.6.0_24/lib
  • Restart the services and access Enterprise Manager.

Correlating the request/response messages in MQ Series Adapter – Oracle SOA Suite

Correlating the request/response messages in MQ Series Adapter – Oracle SOA Suite:

Mapping a response to a request in a request-reply interaction requires correlation.The MQ adapter provide the inbuilt options to correlate the request and response messages, there is no need of implementing the custom correlation to correlate the request and response messages.

Each MQSeries request message contains a message ID and a correlation ID. When an application receives a request message from Oracle BPEL PM, it checks for the correlation schema defined for the response message. Based on the correlation schema, the application generates the message ID and correlation ID of the response message. Based on the Message ID/Correlation ID the request/response messages will be correlated in the MQAdapter.

The below are the two patterns to correlate the request/response messages in MQ adapter.
  • Get Message from MQ and Send Reply
  • Send Message to MQ and Get Reply

Get Message from MQ and Send Reply:

MQ adapter gets a message from the inbound Queue and send a reply message to the outbound bound queue Synchronously/Asynchronously.
  • Create a composite with synchronous/asynchronous BPEL process.
  • Delete the default service created and add the MQ Adapter service

JDBC LLR, table verify failed for table 'WL_LLR_ADMINSERVER'

JDBC LLR, table verify failed for table 'WL_LLR_ADMINSERVER'

I had some issue with the Oracle SOA Suite domain so that tried to delete and re-create the the domain with different name by using the same schema repository.

The domain creation was successful but when starting the server i was receiving the following error.

javax.transaction.SystemException: weblogic.transaction.loggingresource.LoggingResourceException: java.sql.SQLException: JDBC LLR, table verify failed for table 'WL_LLR_ADMINSERVER', row 'JDBC LLR Domain//Server' record had unexpected value 'BLOG_DOMAIN//AdminServer' expected
'blog_domain1//AdminServer'*** ONLY the original domain and server that creates an LLR table may access it ***
        at weblogic.transaction.internal.ServerTransactionManagerImpl.registerLoggingResourceTransactions(ServerTransactionManagerImpl.java:752)
        at weblogic.jdbc.common.internal.RmiDataSource.recoverLoggingResourceTransactions(RmiDataSource.java:302)

        at weblogic.jdbc.module.JDBCModule.activate(JDBCModule.java:359)
        Truncated. see log file for complete stacktrace


The issue is with the table WL_LLR_ADMINSERVER pointing to the old domain/server details.

Steps to resolve the issue

Update the table with the correct domain and the server details.

update SOA_SOAINFRA.WL_LLR_ADMINSERVER set RECORDSTR = 'BASE_DOMAIN//AdminServer' where  XIDSTR  = 'JDBC LLR BASE_DOMAIN1//Server';

Passing parameter to XSLT in Oracle SOA Suite 11g


Passing parameter to XSLT in Oracle SOA Suite 11g

Not like Oracle SOA Suite 10g, in Oracle SOA Suite 11g the parameters can be directly added into the Transform activity from GUI.
The parameters can be of any schema element type; the XML Schema Simple types are not accepted.

Create a schema definition that will have the parameter definition e.g.
Here, I have defined the schema to pass the parameters startIndex and endIndex to the XSLT.

<?xml version="1.0" encoding="UTF-8" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            xmlns="http://schemas.oracle.com/parameters"
            targetNamespace="http://schemas.oracle.com/parameters"
            elementFormDefault="qualified">
 <xsd:element name="parameters">
    <xsd:complexType>
      <xsd:sequence>      
              <xsd:element name="startIndex" type="xsd:string"/>
              <xsd:element name="endIndex" type="xsd:string"/>
            </xsd:sequence>     
    </xsd:complexType>
  </xsd:element>
</xsd:schema>

Create the variable (e.g. parameters) of required element type defined in the schema, in my case the element name is parameters.


Open the Transform activity and select the Input/output variables. Add the parameters variable in the source section, the first variable that is added becomes the source for the transformation activity. These additional variables become as parameters to the transform file.

Invoking the Servlet through HttpAdapter with xml input/output in Oracle SOA Suite

Invoking the Servlet through HttpAdapter with xml input/output in Oracle SOA Suite

Sometimes we may require invoking the Java servlet with XML as input/output; this blog will explain how to invoke the servlet with XML as input/output  through HttpAdapter  in Oracle SOA Suite 11g. The same will work in Oracle SOA Suite 12c - the screens will be little different.

The sample java servlet will receive the emp name and emp no as XML input and return the employee details as XML output.

Defining the HttpAdapter to invoke the servlet:

  • Create a composite with Synchronous BPEL
  • Define the HttpAdapter as shown below
  • Make sure the configuration are defined as below
