Your boss at Certkiller .com wants you to clarify Oracle 10g. Which two steps are
performed the first time any UPDATE statement is issued after the instance is
started? Choose two
A. Creating the parse tree of the statement
B. Writing the modified data blocks to the data files
C.Writing the modified data to the archived redo log files
D.Updating the control file to indicate the most recent checkpoint
E.Updating the data file header to indicate the most recent checkpoint
F.Reading the blocks to database buffer cache if they are not already there
answer:c,d
请问是先写归档日志吗?
