DB2 FOR LUW / DB2FORLUW / A50 - DB2

In cases where multiple update or delete statements are 
occurring on a given column-organized table at the same time, 
one or more of the statements may not act on the correct set of 
rows.  For example, if the following two statements are ran at 
the same time in different transactions: 
 
update t1 set c1 = 5 where c1 = 4; 
delete from t1 where c1 = 5 or c1 = 4; 
 
and the transaction performing the update statement commits 
first, it is expected that the delete transaction will leave the 
table without any rows where c1 = 5 or c1 = 4.  In some 
circumstances, however, the table will be left with one or more 
rows where c1 = 5 or c1 = 4. 
 
Note that this issue ONLY affects tables which were populated 
using an insert-subselect statement on releases 10.5, 10.5 FP1, 
10.5 FP2, or 10.5 FP3.

Populate tables using either LOAD, INGEST, or an insert-values 
statement.  Alternatively, do not run concurrent updates or 
delete statements against the column-organized tables in your 
database which were populated using insert-subselect.
