DB Adapter polling : Not deleting the read records

Question

Hi,
I have a simple BPEL process to poll a database table to delete records after reading them.I tried testing by inserting a single record into the table.BPEL is simply creating new instance (as it is not deleting the read records).
I am using fusion middleware version 11.1.1.3.0.
Also i am not able to view flow trace.I see a row under flow trace but there is no link to open audit trail or flow page.How to enable this.
thanks,
ashok

Hi Naresh,
Here is the contents of jca file:
<adapter-config name="readDB" adapter="Database Adapter" wsdlLocation="readDB.wsdl" xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
<connection-factory location="eis/DB/ArbonneProd" UIConnectionName="ArbonneProd" adapterRef=""/>
<endpoint-activation portType="readDB_ptt" operation="receive">
<activation-spec className="oracle.tip.adapter.db.DBActivationSpec">
<property name="DescriptorName" value="readDB.CustomersToOracle"/>
<property name="QueryName" value="readDBSelect"/>
<property name="MappingsMetaDataURL" value="readDB-or-mappings.xml"/>
<property name="PollingStrategy" value="DeletePollingStrategy"/>
<property name="PollingInterval" value="10"/>
<property name="MaxRaiseSize" value="1"/>
<property name="MaxTransactionSize" value="10"/>
<property name="NumberOfThreads" value="1"/>
<property name="ReturnSingleResultSet" value="false"/>
</activation-spec>
</endpoint-activation>
</adapter-config>
Under trace i see below record:
