Export Parameter : Object_Consistent

specifies whether or not the export utility uses the set transaction read only

statement to ensure that the data exported is consistent to a single point in time and

does not change during the export. if object_consistent is set to y, each object

is exported in its own read-only transaction, even if it is partitioned. in contrast, if

you use the Consistent parameter, then there is only one read-only transaction.


1. Object_Consistent是每个导出的对象都有每个对象的consistent

2. 就算表是分区表 , 就算在导出的过程中被其他用户update,then commit,都是consistent

3. Consistent所有导出的表在同一个Consistent
