Problem IC96750
|
Status: Closed |
LOAD FROM CURSOR MAY ACCUMULATE WINDOWS EVENT HANDLES OVER TIME |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
DB2 database instances on Windows may, over time, accumulate a
large number of Windows handles associated with named events.
This occurs when running a large number of LOAD FROM CURSOR
operations. In some cases this accumulation can contribute to
degraded performance.
Note that this problem does not occur when loading from a
"remote fetch" cursor (i.e. where the cursor is declared using
the DATABASE keyword), and/or when the DB2 system is a
partitioned database environment (DPF).
The number of Windows handles used by the DB2 engine process may
be observed using the Windows Task Manager.
This problem affects DB2 on Windows systems only. |
