The image shows the source database, named ORIG, on the left side, with two arrows pointing away from it.
The arrow pointing up from the source database, ORIG, to the database export of ORIG above it is labeled "expdo" for the export process. The export of ORIG has two arrows pointing away from it. One of the arrows is labeled "impdp non-sharded process," and the other is labeled "impdp sharded process." The impdp non-sharded process points to the shard catalog database, named CTLG. The impdp sharded process splits into three arrows pointing to three database shards, named SHRD1, SHRD2, and SHRD3.
The second arrow pointing from the database source, ORIG, points down to a string of Oracle GoldenGate processes and trail files. The string begins with the Extract process, named exch. The Extract process points to local trail files. The local trail files point to the Pump, named pmsh. The Pump points to remote trail files. The remote trail files point to a Replicat process, named rpsh. Finally, the Replicat process points to the shard catalog database, named CTLG.
