Your single-instance Oracle 12c database home currently supports conventional auditing and uses Automatic
Storage Management (ASM). You want to enable unified auditing by executing the command:
$ make –f ins_rdbms.mk uniaud_on ioracle ORACLE_HOME=$ORACLE_HOME
Which two steps should you perform before executing this command?
Ensure that the initialization parameter AUDIT_TRAIL is set to DB.
Drop any existing fine-grained audit (FGA) policies.
Stop the listener.
Shit down the database instance.
Disable auditing by setting the initialization parameter AUDIT_TRAIL to NONE.
