Specifies whether Import should commit after each array insert. By default, Import commits only after loading each table, and Import performs a rollback when an error occurs, before continuing with the next object.
If a table has nested table columns or attributes, then the contents of the nested tables are imported as separate tables. Therefore, the contents of the nested tables are always committed in a transaction distinct from the transaction used to commit the outer table.
COMMIT=n and a table is partitioned, then each partition and subpartition in the Export file is imported in a separate transaction.
For tables containing LOBs,
TIMESTAMP columns, array inserts are not done. If
COMMIT=y, then Import commits these tables after each row.
