Description: Utilities in Oracle Database 10g take performance and versatility to new levels.Before Oracle Database 10g, (Oracle7 through Oracle9i) the import and export utilities ran as clients and did the bulk of the work. Data being exported was read by the database instance, passed over the connection to the export client, and then written to disk. All the data was single-threaded through the one export process. Data volumes today are often magnitudes larger than when this architecture was first put in place, making that single export process a bottleneck because performance of an export job is limited by the throughput that the export utility can sustain.
