APAR Error Description / Circumvention

-----------------------------------------------
When a column that is a non-normalized UTF-8/1208 field is
altered to a UTF-16/1200 normalized data type, data can be
truncated.  For example:

CREATE TABLE T1
(COL1 VARCHAR(2048) ALLOCATE(30) CCSID 1208 NOT NULL DEFAULT '')

INSERT INTO T1(COL1) VALUES ('123456789')

ALTER TABLE T1 ALTER COLUMN COL1
SET DATA TYPE VARGRAPHIC (2048) ALLOCATE (30) CCSID 1200
NORMALIZED DEFAULT '' NOT NULL ;

Data in COL1 is truncated.

CORRECTION FOR APAR SE66764 :
-----------------------------
Copying the data to the NORMALIZED field is corrected to no
longer truncate the data.  The ptf is preventative.  To recover
the truncated data, restore from backup.

CIRCUMVENTION FOR APAR SE66764 :
--------------------------------
Normalize the data prior to altering the column to CCSID 1200:

ALTER TABLE T1 ALTER COLUMN COL1
SET DATA TYPE VARCHAR(2048) ALLOCATE(30) CCSID 1208 NORMALIZED
