Answer 1

The SQLCODE -204 means "Undefined name". It is a DB2 error code indicating 'object does not exist'. The SQLERRMC value helps provides you more specific information. In your case what can't be found is the table USER14336.DDP_DIR . Double check the schema name ( USER14336 ) and the table name ( DDP_DIR ). Please check also the VCAP_SERVICES environment variable of your application to see if you are using the correct username (as schema name). You can also omit the schema name if there is only one (in this case DB2 uses the default one).
