FLASHBACK_TIME

Default: There is no default

Purpose

The SCN that most closely matches the specified time is found, and this SCN is used to enable the Flashback utility. The export operation is performed with data that is consistent up to this SCN.

Syntax and Description

FLASHBACK_TIME="TO_TIMESTAMP(time-value)"

Because the TO_TIMESTAMP value is enclosed in quotation marks, it would be best to put this parameter in a parameter file. See "Use of Quotation Marks On the Data Pump Command Line".

Restrictions

• FLASHBACK_TIME and FLASHBACK_SCN are mutually exclusive.

• The FLASHBACK_TIME parameter pertains only to the flashback query capability of Oracle Database. It is not applicable to Flashback Database, Flashback Drop, or Flashback Data Archive.

Example

You can specify the time in any format that the DBMS_FLASHBACK.ENABLE_AT_TIME procedure accepts. For example, suppose you have a parameter file, flashback.par, with the following contents:

DIRECTORY=dpump_dir1
DUMPFILE=hr_time.dmp
FLASHBACK_TIME="TO_TIMESTAMP('27-10-2012 13:16:00', 'DD-MM-YYYY HH24:MI:SS')"

You could then issue the following command:

> expdp hr PARFILE=flashback.par

The export operation will be performed with data that is consistent with the SCN that most closely matches the specified time.
