I'm running 9.2.0.5 Ent Ed. DMTs, compatible param=8.1.0, on Unix
AIX5L.
In my instance I have a production data schema. I also have a schema
that we use to test production applications against non-production
data. Periodically I have to refresh that non-production data with more
realistic/up-to-date production data.
Currently there is a script that basically exports the production
schema, then drops all tables from the test schema, and finally imports
the production data into the test schema.
I was thinking that it may be easier and more efficient to just drop
the user for the test schema and then re-create that user and import
the production tables.
I was also considering truncating all the test tables as an option, but
in some cases we need to adjust the initial and next sizes of table
extents. If you truncate a table can you resize the initial extent?
Overall what would you consider the best way of doing this refresh of
data?
