Subject Datapump and Orphan pages
Author Adriano Wolff - Sinprod

I have two questions:

a) I have a database that is currently with 121MB. I created a new empty
database and transferred the data of the previous one to the this new with the
Datapump. After transference the new base had only 77MB. I didnĀ“t understand
because of as much difference. Somebody would know to inform me what it could
be ?

b)The database with 121MB presented some problems due the energy falls. When
using the IBCONSOLE to effect the validation of the archive, the same presented
me message that would have "pages orphans". Somebody could say me what they are
these pages orphans, and if this can compromise the database.
