We faced the issue while starting the weblogic managed server, the status of the server struck in STARTING.

W could not able to find a valid error messages in the log files

Managed Server Log File:

<30-Oct-2013 11:13:29 o'clock GMT> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to STARTING> 

No logs are getting printed after this.

Node Manager Log File:

<30-Oct-2013 11:09:44> <INFO> <SOACoreDomain> <MS1> <Server failed during startup so will not be restarted>
<30-Oct-2013 11:09:44> <WARNING> <Exception while starting server 'MS1'>

The root cause of this issue is somehow the ldap directory of the server got corrupted.

To resolve this issue:
  •  Kill the managed server 
  •  Remove the ldap folder from the following location  <<DOMAIN_HOME>>/servers/<<Managed Server>>, this file will be auto generated while restarting the server.
  • Restart the server

Tracking the messages in Oracle OSB

This blog will explain how to track the message for a Oracle OSB flow with unique key.

In oracle OSB we can assign a Report key to the proxy service and based on this key the messages can be tracked.

I have developed a proxy service based on business service that invokes a Employee BPEL, this blog will explain how to track the employee messages with employee id.

Open project in OSB console and also create a session

Click on View Message Flow of proxy service


Click on EmployeePS and Add Pipeline Pair


Add a stage on Request Pipeline and Edit the stage



Add a Report action


Configure the expression, Key Name and Key Value(Selected from ) as shown below, the Key Value can be selected from expression Editor.





Save and Activate the session.

Tracing the Message:

Initiate the Employee Proxy service through Test Console



Click on Operations and click on Message Reports and enter the key and value this will display all the instances of messages with this key

Click on Report Index Empid=24 and click on Detail in the Report Body section, this will display the input message to the service

ORABPEL-05250 Error - JDeveloper Part1

I faced a strange ORABPEL-05250 issue while deploying the composite to Oracle SOA Suite Server through JDeveloper.

The composite was successfully build in JDeveloper but during deployment to the server received the following exception.

[03:59:18 PM] Sending internal deployment descriptor
[03:59:18 PM] Sending archive - sca_SFDCOT_Invoker_rev1.0.jar
[03:59:38 PM] Received HTTP response from the server, response code=500
[03:59:38 PM] Error deploying archive sca_SFDCOT_Invoker_rev1.0.jar to partition "CRMASYNC" on server AdminServer [http://localhost:8000] 
[03:59:38 PM] HTTP error code returned [500]
[03:59:38 PM] Error message from server:
There was an error deploying the composite on AdminServer: Error occurred during deployment of component: SFDCOT_Invoker to service engine: implementation.bpel, for composite: SFDCOT_Invoker: ORABPEL-05250

Error deploying BPEL suitcase.
error while attempting to deploy the BPEL component file "/oracle/as01/fmw/config/admin/domains/SOACoreDomain/servers/AdminServer/dc/soa_b3d3a863-3515-4d6d-9b7f-0d0c7d1977a6"; the exception reported is: java.lang.Exception: BPEL 1.1 compilation failed

ORABPEL-05250 exception can occur for number of reasons . After a long struggle( tried removing the partner links one by one) received the actual error

There was an error deploying the composite on AdminServer: Error occurred during deployment of component: SFDCOT_Invoker to service engine: implementation.bpel, for composite: SFDCOT_Invoker: ORABPEL-09705

Could not initialize variable.
An error occurs while initializing BPEL variable inputVariable; the schema processor cannot find the element {http://xmlns.oracle.com/pcbpel/adapter/db/top/SFDCOT_POLLING_V}SfdcotPollingVCollection in the following schemas: oracle.fabric.common.wsdl.SchemaManager@7eb126f4.
The XSD element on which the variable was based was not properly defined in XSD or the WSDL.

Ensure that the element named in the error message is valid in the XSD or the WSDL.

The issue is due to schema name in the wsdl file is wrongly specified(wrong case) even though the schema name was wrongly specified in wsdl the composite was able compile and build successfully in JDeveloper installed in windows but failed while deploying to the server running in UNIX, this is due to case sensitive nature of file names in UNIX OS


After correcting this issue the composite got deployed successfully.

The WSDL is not semantically valid: The element or type specified for part'payload' in message cannot be found in any schemas referenced by this wsdl - Oracle OSB

While creating the WSDL resource in OSB with inline schema refereed to create the message types we may receive the following exception even though the wsdl is valid

An error occurred creating the resource:
The WSDL is not semantically valid: The element or type specified for part'payload' in message '{http://www.tr.com/ns/2013/10/14/SAP/EAI/AAALM/LicenseManagement}PositionEntitlementRequestMessage' cannot be found in any schemas referenced by this wsdl.


WSDL File:

  <wsdl:operation name="process">
   <wsdl:input message="client:PositionEntitlementRequestMessage"/>
  </wsdl:operation>
 </wsdl:portType>

</wsdl:definitions>

The issue is the namespace prefix client is not able to access the element MT_EntitlementStatus.

To resolve this issue add the the targetNamespace attribute in schema definition as shown below

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions name="SAPOM_PositionEntitlement"
                  targetNamespace="http://www.tr.com/ns/2013/10/14/SAP/EAI/AAALM/LicenseManagement"
