John, alter session set events 'immediate trace name ADJUST_SCN level 1' bumps the current SCN By one billion. I have used this event once while recovering a Tera Byte database where LGWR crashed and all the data files were inconsistent.
And also there is an undocumented paramter something like _Max_Giga_SCN which starts (!!) the SCN at higher values. Have anyone used that?

Gopal - how do you set or access this event? Volunteers: Just a word of warning - if you want to implement this on a Dev/Test database, make sure that it is not connected as a source or target to ANY other database via DBLinks. Otherwise you will find that these high SCNs migrate across to all others as if it were a cold virus. Such a database has to be absolutely quarantined...
