Re: Huge import takes a long time

Are they local indexes?
How about importing into another table, add the indexes and use exchange partition, it's probablly your best bet? I don't know if you would be able to import right into the table by marking the local index unusable.

Subject: Huge import takes a long time

I've got a massive import that takes a long time. This is one I'd love to drop and recreate the index, but that alone would probably be almost a terabyte, so that is out of the question.

This is a table partitioned by month and a normal partition is about 20-24GB. As it's coming in, it's getting a lot of I/O wait on the index datafiles, but only the datafiles of that partition. The index is also partitioned.

This is now 9.2.0.6, so just how high can you set up the buffer?

Are there any other "tricks"?

As I get to the "end" of the partition my import rate is getting to be 2-3GB per day.

Yuck!!!
