Information in this document applies to any platform.

Purpose

 This document explains the purpose of the new export parameter RESUMABLE while exporting a 9i database.

Scope

 You can sort the exported data and therefore need a temporary segment for sorting.
 You may encounter a storage space allocation issue regarding the temporary segment required.

  The RESUMABLE parameter allows the export to
    1. suspend if a space allocation issue occurs
    2. wait until the space allocation issue is solved
    3. then resume
  and therefore not to abort, provided a timeout is set appropriately.

  Since the default value for the RESUMABLE_TIMEOUT parameter is 7200 seconds (2 hours), this means the DBA has 2 hours by default to fix the error before the export aborts.
