If I use EM to Export Data like:
EM -> Data Movement -> Export to Export Files -> Schemas ->
When step 2 -> Export: Options -> Show Advanced Options, it can select:
Code: Select all
1. As the specified System Change Number (SCN)
it show a SCN, i think it is the most current SCN of my DB.
2. As the SCN which most closely matches the specified time
it show current time.
The question i want to ask is:
For command backup, i can use option like "flashback_time=systimestamp" but inside the EM,
it always give me a SCN number or a time.
If I scheduled this EM task as a scheduled jobs, do you think this SCN will be
updated (every day backup should have different SCN, right?) when each run ?
