Hi, I'm just wondering how you guys know so many undocumented Oracle parameters and what to do with them and things like that.
Please don't answer "because we're smart" ... that would be stating the obvious. Cheers, Sujatha PS: "undocumented Oracle parameters" makes it OnT rather than a philosophical musing. -----Original Message----- Sent: Wednesday, 13 March 2002 2:23 PM To: Multiple recipients of list ORACLE-L 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...
