FAST Forum

Hi Everyone,

I am totally new to the FAST ESP prodyct and trying to configure the JDBC connector for searching from a SQL Server database. While the collection creation goes fine, I am ending up with a series of errors while processing the database records. All the errors are raised by a module called CCTKCallbackHandler (there is no error from JDBCConnector module). There is one error message per record in the database, all of which says:

Document: 1, operationId: 1 failed in: processing

Processing Error[document id="1" code="16" description="ERROR: Missing input attribute: "data"" suggested action="DROP" component="processing" processor="FormatDetector"]

(The document id 1 here is the value of my primary key in the table, the messages repeat for every record)

Can somebody please help me. This is very urgent.

Thanks,
Soma

Hi,
the CCTKCallBackhandler is the callback-handler of the framework with which the JDBC connector is built.

The error is really self-explainatory: "missing attribute data"

All the fields you select in your sql query are translated into FAST document-attributes. The pipeline you are using apparently contains one or more stages for which the data-attribute is mandatory. Either modify your pipeline (as you're not providing a data-attribute you probably have no use for those stages) or make sure the jdbc-connector returns a (empty) data-field.

Thank you for the help Edward. Sorry for asking silly questions, but I am not only new to FAST, its my first time in the Enterprise Search area as a whole.

The collection preparation went fine after changing the pipeline from Generic to Express. Having trouble with searching the data though, trying to figure out the problem right now.

Thanks a lot again for the help.
