DB2 FOR LUW / DB2FORLUW / 970 - DB2

Under very rare scenarios, DB2 might give a SQL0901N error 
message. 
A. The query has a RATIO_TO_REPORT olap function 
B. The datatype of the input expression is not decfloat 
 
Example: 
 
select t1.c1, ratio_to_report(sum(cast(t1.volume as float)))OVER 
(Partition By t1.c1) 
  from t1 
  where t1.c2 = 1 
  group by t1.c1; 
 
SQL0901N  The SQL statement failed because of a non-severe 
system error. 
Subsequent SQL statements can be processed.  (Reason "".) 
SQLSTATE=58004
