Status: Closed |
DB2 instance terminates abnormally or returns -901 compiling a query |
| product: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
Compiling a query on DB2 v9.5 fix pack 5 may result in the DB2
instance terminating abnormally with a stack similar to this
example from Linux:

0x0171
Another possible symptom of this problem is SQLCODE -901 with
one of the two following reason codes:
SQL0901N The SQL statement failed because of a non-severe
system error.
Subsequent SQL statements can be processed. (Reason "invalid
qnc assigment".)
SQLSTATE=58004
or
SQL0901N The SQL statement failed because of a non-severe
system error.
Subsequent SQL statements can be processed. (Reason "column
number out of range".)
SQLSTATE=58004
To hit this problem, a query must have an outer join whose
result is inner joined with a base table and there must be a
join predicate, for example:
create view V as select * from T1 left outer join T2 ...
select * from V, T3 where V.C1=T3.C2
The problem only occurs on DB2 v9.5 fix pack 5. |
