The error states that the source is not available to load the data and filename i.e table name is not present in the datafragment table for that particular data load.

Cause:
=====
By looking at the datafragment table the sourcetablename is empty because of this the elink.log shows undefined i.e it takes the name as null.
=====
 

Unable to load data using datasource format as database

Product: TIBCO MDM Version: 9.x OS: All Supported Operating Systems

To resolve this issue update the datafragment table with correct sourcetablename i.e table name.

To get the datafragment id for particular datasource use the below query:

SELECT id FROM datafragment where name='DATASOURCE_NAME';

update  datafragment set sourcetablename='Table_Name' where id=XXXX;

commit;

where XXXX is the datafragment id of the datasource

Example: Suppose user have TEST_DB_LOAD datasource and table name DBLOAD

To get the datafragment id use the below query:

SELECT id FROM datafragment where name='TEST_DB_LOAD';

And the update the sourcetablename in the datafragment table using below query:

update  datafragment set sourcetablename='DBLOAD' where id=YYYY;

commit;

where YYYY is the datafragment id of the datasource.
