Robert,

I think you can **artificially** force a database to reach the SCN to
0xfffffff.ffff by using the event ADJUST_SCN.
This bumps the SCN to one billion if set at level 1. So running them in a
loop will bump the SCN to the max value.
THis event generally used to bump the SCNs if there is a mismatch between
file headers which is signaled by
ORA-00600 [2662].

Any volunteers?

I wonder if any Oracle database has ever yet experienced an absolute SCN
wrap??

Ok Jeremiah,
I'll warrent that Redo sequence# is a uneven measuring stick.

Longest since last restart - 6/22/01
Oldest                     - 7/24/96
Highest SCN                - a pokey 366 802 309

What kind of environment gets you to a 13-digit SCN?

Mike
