Hi all,

Can anyone enlight whether, is there any way to know PX Resource Consumption, and then changing PX stages to achive minimum resource consumption by the partcular PX job (e.g. to process 100m rows). I am kind of curious to know the answer. (other details: 8 CPU, AIX 5.x). I checked earlier postings, couldn't get convincing idea.

Thank you,

Resource consumption can be monitored at the UNIX level, watching the osh processes. You can find which pid belongs to which by inspecting a combination information in Director and your configuration file.
Whether you can modify stages to be more efficient depends on whether they are optimally written in the first place. You may get better gains by changing the configuration file (throwing more resources at the task).
