DB2 FOR LUW / DB2FORLUW / 970 - DB2

This problem can occur in a database using UCA-based collation 
during query compilation of an SQL statement that contains one 
or more equality join predicates that reference columns of type 
CHAR, VARCHAR, GRAPHIC, VARGRAPHIC and one or both of the 
columns in the join predicate have distribution statistics 
collected.  The problem does not occur if the character type is 
FOR BIT DATA. 
 
You can identify that you hit this problem if the following 
function list is found in the trap file stack trace: 
 
sqlnlsICUstrcollUTF16BE 
sqlv_g_varUCA_comp 
sqlrxcp2 
sqlno_compare_literal 
sqlno_nud_compare_literal 
sqlno_ff_updateEffHighLowKeys 
sqlno_ff_col_eq_col 
sqlno_ff_compute_atomprd 
 
This problem was first introduced in the following DB2 releases: 
 
Version 9.5 Fix Pack 8
