DB2 FOR LUW / DB2FORLUW / A50 - DB2

Ingest can perform poorly when the INGEST command omits the 
field list and specifies a target table that has a lot of 
user-defined data types (UDTs).  For example, ingesting 100K 
rows into a 300-column table that has 75 columns whose type is a 
UDT took 32 times as long as import (16 minutes vs. 30 seconds).

* USERS AFFECTED:                                              * 
* Ingest users using UDTs on DB2 V10.1 Fixpack 2 or lower.     *

* See Error Description                                        * 
**************************************************************** 
* RECOMMENDATION:                                              * 
* Upgrade to DB2 for LUW Version 10.5 Fixpack 3 or higher.     * 
****************************************************************

There are two possible work arounds: 
 
(1) Define an explicit field list on the INGEST command.  For 
example: 
 
INGEST FROM FILE my_file.del FORMAT DELIMITED 
( 
   $field1 INTEGER EXTERNAL, 
   $field2DECIMAL(5,2) EXTERNAL, 
   ... 
   $fieldn CHAR(10) 
) 
    INSERT INTO my_table_with_many_udts; 
 
(2) Modify the table to use built-in types instead of 
user-defined types.
