Error While Polling Database changes using Custom SQL

Question

Hi,
I am using Oralce SOA Suite 11g DbAdapter for polling Database changes.
My source database is DB2,I am using custom query for polling the changes in source database.
I am using "Update an External Sequencing Table on a Different Database" polling Strategy
Query section of the Mapping file is as follows.
<querying xsi:type="query-policy">
<queries>
<query name="ReceiveF554102TXEDataSelect" xsi:type="read-all-query">
<call xsi:type="sql-call">
<sql><![CDATA[SELECT FILE_NAME, LIBRARY_NAME,
               USER_NAME, SEQUENCE_NUM,
               JOURNAL_CODE, ENTRY_TYPE, TIME_STAMP, JOB_NAME, JOB_USER,
               JOB_NUMBER, PROGRAM_NAME, ARM_NUMBER, ADDRESS_FAMILY, RMT_ADDRESS,
               REMOTE_PORT, SYSTEM_NAME, REL_RECORD, OTRCLN, IBMCU, IBITM, IBLITM,

               IBUPMJ FROM PY_JRNMON.F554102T WHERE ((TIME_STAMP > (SELECT LAST_READ_DATE FROM SOALIB.SOASEQHDR WHERE (TABLE_NAME = 'F554102T'))) AND (TIME_STAMP < SYSDATE)) ORDER BY TIME_STAMP ASC]]> </sql>
</call>
<reference-class>ReceiveF554102TXEData.F554102T</reference-class>
<lock-mode>none</lock-mode>
<container xsi:type="list-container-policy">
<collection-type>java.util.Vector</collection-type>
</container>
</query>
</queries>
<delete-query xsi:type="delete-object-query">
<call xsi:type="sql-call">
<sql>UPDATE SOALIB.SOASEQHDR SET LAST_READ_DATE = #LAST_READ_DATE WHERE (TABLE_NAME = 'F554102T')</sql>
</call>
</delete-query>
</querying>
I am getting following Error after defining the custom SQL in my mapping.xml file. (After executing the Created Process)
Caused by: BINDING.JCA-11622
Could not create/access the TopLink Session.
This session is used to connect to the datastore.
Caused by BINDING.JCA-11626
Query Not Found Exception.
Could not find Named Query [ReceiveSampleCustomPollSelect] with ? arguments, belonging to Descriptor [ReceiveSampleCustomPoll.F554102T] for [oracle.tip.adapter.db.DBActivationSpec@2ec733b0] inside of mappings xml file: [ReceiveSampleCustomPoll-or-mappings.xml].
You may have changed the queryName info in either the _db.jca or toplink-mappings.xml files so that they no longer match.
Make sure that the queryName in the activation/interactionSpec and in the Mappings.xml file match. If an old version of the descriptor has been loaded by the database adapter, you may need to bounce the app server. If the same descriptor is described in two separate Mappings.xml files, make sure both versions include this named query.
You may need to configure the connection settings in the deployment descriptor (i.e. DbAdapter.rar#META-INF/weblogic-ra.xml) and restart the server. This exception is considered not retriable, likely due to a modelling mistake. This polling process will shut down, unless the fault is related to processing a particular row, in which case polling will continue but the row will be rejected (faulted).

Help required to fit custom SQL in mapping.xml file for complex queries.
Thanks,
Arun Jadhav.

Answer 1

"Execuite Custom SQL" in DB adapter and you'l get it.
But in this case you'll have to implement your own polling strategy (if you need one).
If you want to use one of the predefined polling strategy you should use "Poll for New or Changed records" and import all the tables you use and connect them in wizard.
