How to find if job is IO limited

Hi,

I was looking for some help on lookup stage and found an interesting discussion on IO limited jobs.

How can I find if a job has performance limitations due to IO.

Thanks,

Shashank

Use the Performance Analysis tool in DataStage.

Hi Ray,

I opened the performance analysis tool. I could see various charts but could not interpret them to arrive at a conclusion in terms of bottleneck.

Is there any document available on this tool apart from a short section available in Advanced parallel guide.

Thanks,

Shashank

The tool is covered in better depth than in the manual in the IBM class "Advanced DataStage".
