Backup on 9i

   Hi all,

   My db is 9.2.0.4 64 bit on Unix AIX and size about 300GB

   Because of I need create new database (copy of primary db) for testing but run on Linux OS, so I must use export/import to do this work. I want ask about some parameters to make exporting faster

    + BUFFER: Calculate buffer size may help fetch more row at a time (buffer_size = rows_in_array * maximum_row_size). If I export from remote machive (another server not server that exist db), this value still effect ? And if it still effect, buffer size is RAM that oracle (maybe oracle client) get to serve exporting ?.
