Status: Geschlossen |
COLUMN BASED QUERY MAY HANG IF THE QUERY CONTAINS AGGREGATION FUNCTIONS AND DATA EXCEPTION OCCURS |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problembeschreibung: |
A column based query may hang if it meets the following
conditions:
1. Containing aggregation functions such as group by, SUM etc.
2. Data exceptions may occur for aggregation functions e.g SUM
in the query has exceeded a data type limit (for example hitting
the maximum integer size)
During the hang period in db2pd -latch output, there are many
latch waiters waiting on
SQLO_LT_ibm_cde__query__GroupByControlBlock__mErrorAndWarningMut
ex latch, but there is no latch holder.
In db2diag.log, the similar messages may be observed.
