Would that be on race day or between races?

smon_scn_time table is the table that Oracle uses to keep track of the 
relationship between scns and timestamps for flashback operations. It contains 
up to 5 uptime days of data (unless you have hacked it...but that is another 
story and NOT to be done on a PRODUCTION database!). It is relatively small 
(thousands of rows, not millions) so it should not take long to rebuild it...if 
it can be rebuilt. Since this table is constantly inserted/updated by smon, the 
window may be small, but the small size of the table should work for your 
benefit. I've never rebuilt the index, so I can't say for certain.

As smon_scn_time is owned by SYS, it can't be exported. However, you could try 
a rebuild on a NON-PRODUCTION system first.

More seriously though, it really depends on the entire environment:
* HW
* how busy is it
* storage system capacity
* etc, etc, etc.

Export the table (if possible) and import it to a database on a development
or test server. --
