Problem IC81849
|
Status: Closed |
NOT ALL CASTOUT ENGINES ARE HELPING WITH SYNCHRONOUS CASTOUT REQUESTS |
| product: |
DB2 FOR LUW / DB2FORLUW / 980 - DB2 |
| Problem description: |
Due to an issue in waking up castout engines, fewer castout
engines than configured may end up working on a set of castout
requests. In some cases, the same castout engine may get woken
up repeatedly, which may result in sub-optimal performance when
processing castout requests. This problem is less apparent on
I/O-bound clusters where most castout engines are already busy
processing I/O requests. |
