BPEL Process Manager Oracle BPEL Domain Initialization Failed

Question

I was able to login into BPEL Process Manager without any error. Then I changed one entry in the oc4j-ra.xml file and restarted the BPEL server and started getting the error message.
Oracle BPEL Domain Initialization Failed
The Oracle BPEL Domain default did not initialize successfully. The following error was detected during startup. Please contact the Oracle Support
Team if you are not able to resolve this problem.
Reported Error:
Cannot lookup jdbc datasource.
The process domain was unable to lookup the TX datasource "eis/DB/DBConnection1".
Please check that the machine hosting the datasource is physically connected to the network. Additionally check that the
connection pool properties as defined in the application server startup
properties are valid.
I put back the original oc4j-ra.xml back in appropriate dir , restarted the BPEL server and database server still getting the same errro message listed above, It's urgent can anybody post the possible solution/suggestion experience.
Thanks

Answer 1

I opened the file under
./application-deployments/default/DbAdapter/oc4j-ra.xml and it has the following entry
<connector-factory location="eis/DB/DBConnection1" connector-name="Database Adapter">
<config-property name="xADataSourceName" value="jdbc/DBConnection1DataSource"/>
<config-property name="dataSourceName" value="loc/DBConnection1DataSource"/>
<config-property name="platformClassName" value="oracle.toplink.platform.database.Oracle9Platform"/>
<config-property name="usesNativeSequencing" value="true"/>
<config-property name="sequencePreallocationSize" value="50"/>
<config-property name="defaultNChar" value="false"/>
<config-property name="usesBatchWriting" value="true"/>
<connection-pooling use="none">
</connection-pooling>
<security-config use="none">
</security-config>
</connector-factory>
I opened that file (
./connectors/DbAdapter/DbAdapter/META-INF/oc4j-ra.xml) and it has no entry for
<connector-factory location="eis/DB/DBConnection1" connector-name="Database Adapter">
<config-property name="xADataSourceName" value="jdbc/DBConnection1DataSource"/>
<config-property name="dataSourceName" value="loc/DBConnection1DataSource"/>
<config-property name="platformClassName" value="oracle.toplink.platform.database.Oracle9Platform"/>
<config-property name="usesNativeSequencing" value="true"/>
<config-property name="sequencePreallocationSize" value="50"/>
<config-property name="defaultNChar" value="false"/>
<config-property name="usesBatchWriting" value="true"/>
<connection-pooling use="none">
</connection-pooling>
<security-config use="none">
</security-config>
</connector-factory>
So I entered this and restarted the BPEL PM but still no luck,
Is anything else I will be looking in that file let me know
