Re: couchman doubt

It's the SCN. I don't think the question asked of you was terribly clear.

Yes I have 9.0.1.1.1 enterprise edition availible on win32 I tested the given query out and the checkpoint_change# column value from v$database matches the result of the query you gave You mean to say that couchman is asking me where to find the checkpoint number ?

Q. You want to find out the current sequence number stored in your control  file for backup purposes. Which two of the following views would you query?

 A*. V$DATABASE  B . V$CONTROLFILE  C . V$PARAMETER  D*. V$CONTROLFILE_RECORD_SECTION  My doubt : what sequence number is he asking for ? I can get the current  log sequence number from v$controlfile_record_section by :  select type , last_recid from v$controlfile_record_section where type =  'LOG HISTORY' ;
 There are other sequence numbers in v$database but why would I need the : CHECKPOINT_CHANGE# OR CONTROLFILE_SEQUENCE# for backup ( thats what the question asks ) . I cannot understand his answer of 'A' and 'D' both.
