As part of a manual upgrade process, after installing the software for Oracle Database 12c and preparing the new Oracle home, you shut down the existing single-instance database.
Which step should you perform next to start the upgrade of the database?
A.
Start up the database instance by using the new location of the server parameter file and run the catuppst.sqi script to generate informational
messages and log files during the upgrade.
B.
Start up the database instance by using the new location of the server parameter file and run the cact1.pl script from the new Oracle home to use
parallel upgrade options that reduce down time.
C.
Start up the database instance by using the STARTUP UPGRADE command and gather fixed object statistics to minimize the time needed for
recompilation.
D.
Start up the database instance by using the STARTUP UPGRADE command, which opens the existing database, and then performs additional
upgrade operations.
