Which three statements are true in this scenario?

You modified the Linux memory map and lowered mapped base for Oracle shared libraries to increase the System Global Area (SGA) size. Which three statements are true in this scenario? (Choose three.)

A.
You cannot use the extended buffer cache feature.

B.
You cannot use the Oracle Enterprise Manager (OEM) console.

C.
All the components of SGA can make use of the additional memory allocated to SGA.

D.
The database will not support dynamic SGA and multiple data block sizes.

E.
You may need to retune the SORT_AREA_SIZE parameter because less virtual memory remains available for Program Global Area (PGA).

F.
You must ensure that every Linux shell that spawns an Oracle process must have the same lowered mapped base as that for the Oracle shared libraries.
