RE: Need some ideas, WIN vs. LINUX... Same process on Win takes much less temp space than on Linux

Possibly compare pga_aggregate_target, but that would not explain the vast difference. If the difference were in megabytes (rather than gigabytes) this would be the first place I would look.

Another possibility is that statistics are stale one or both machines, so execution plans are not the same ?

Subject: Need some ideas, WIN vs. LINUX... Same process on Win takes much less temp space than on Linux

So, I need some thoughts to bounce around here. Running 10.2 Standard edition on Win and 10.2 Enterprise edition on Linux RH 5. I have the same
database, the same data. Building a Materialzed View on the Win box never
requires the temporary tablespace be more than about 500mb. While on the LINUX box we are gobbling up about 175GB of space. Any idea why we might see
such a vast difference?
