Cherie,
If network bandwidth is the bottleneck, the use of Fast Refreshable
snapshots will be a great help. Whereby you only pull the rows that have
changed since the last refresh across to the primary.

Please respond
to ORACLE-L
Our developers sent me a function which is running quite long to see if I
could give them any advice. It is written in PL/SQL for version 9.2.0.1
of Oracle on Sun Solaris. It is going across a database link. It reads
tables in one database and loads a new table in a datamart table on another
box. It looks like it will currently run for four or five days to load a
140 million-row table, which is longer than our available window.
I am wondering if anyone can look at the big picture and see if there are
any obvious places for improvement of this overall design. I am open to
any suggestions that I can relay back to the developers.
My gratitude to anyone who can wade through this and recommend
improvements.
