Hi All,
I have DB2 EEE 7.2 12 db partitions running on AIX 5.1ML5 P690( one
server). The AIX workload manager is on. I started the same peoplesoft
job on all 12 nodes at the same time. But some node(partition)
processing speed are much faster than the others. The fastest node
took 15 hours. But the slowest node took 17 hours.
According to DBA, the data are evenly disributed on 12 partitions. The
configuration of the partitions are same. All the job have same
priority on the OS. The jobs used all the CPU resource (reached WLM
CPU hard limit). I think maybe the partition were compete the CPU
resource which cause the partition speed were different.
Could anyone give me some advice why the DB2 nodes cannot share the
system resource evenly? Why some nodes faster?
Thanks.
John
