Hello, all.
DB2 v9.5.1 ESE, Windows 2003 Server 64-bit, 4 CPU (8 cores) each, DPF
environment.
There are 2 DPF instances on the same set of 5 computers.
One computer holds coordinator partitions and other 4 hold partitioned
tables (2 logical nodes per computer).
Application:
DataStage v8 running some (say 32) parallel massive single row inserts
(actually we use compound inserts: insert into table values
(?,..,?), ..., (?,...,?) ).
All inserts go through the coordinator partition and only into 1
database.
We don't use some advanced technique for inserts like local bypass or
INSERT BUF bind option.
intra_parallel parameter is off.
And we see that on each computer that holds partitioned tables 2 cores
are loaded almost on 100% and other 6 cores are almost idle.
It seems that such CPU usage is bottleneck of this workload.
My questions are:
Is the way to make db2 use all cores during such workload?
Has somebody encountered such problem?
Thanks in advance,
Mark B.
