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!!!
