Examine the parameter setting in your database:Which statement is correct about the database?()
A. Automatic memory management is disabled because PGA_AGGREGATE_TARGET and SGA_TARGET are not setB. The instance is started but the database will not be opened until PGA_AGGREGATE_TARGET and SGA_TARGET are setC. The database is opened but users cannot perform transactions until PGA_AGGREGATE_TARGET and SGA_TARGET are setD. Automatic memory management is enabled and, as per policy, 60% of the memory for System Global Area (SGA) and 40% of the memory for Program Global Area (PGA) will be distributed at startup
考题
You specify a nonzero value for the MEMORY_TARGET initialization parameter,but do not set the PGA_AGGREGATE_TARGET or the SGA_TARGET parameters. You restart your database instance. Which statement about the result is true?()A、 The database instance starts,and Oracle sets the default value of SGA_TARGET to the same value as SGA_MAX_SIZEB、 The database instance starts,and Oracle automatically tunes memory and allocates 60 percent to the SGA and 40 percent to the PGAC、 The database instance starts,but Automatic Memory Management is disabledD、 The database instance will not start because you did not specify the PGA_AGGREGATE_TARGET or SGA_TARGET parameter
考题
Your database is configured in shared server mode. However, your senior DBA asks you to modify the value ofthe PRIVATE_SGA limit in the profile of the users.

考题
Which statement about Automatic Memory Management with Oracle 11g is true?() A、 You cannot specify MEMORY_TARGET if you explicitly specify SGA_TARGET or PGA_AGGREGATE_ TARGET values that are greater than zero in your parameter file.B、 Oracle can reallocate memory between the SGA and PGA automatically as needed.C、 To use Automatic Memory Management, you must explicitly set both the MEMORY_TARGET and MEMORY_MAX_TARGET parameters in your parameter file.D、 You can set the MEMORY_TARGET parameter to a maximum value of the current SGA size plus the current PGA size.
