Well one of the Know-it-all DBA asked me this question (He was trying to test me )

RAM : 8 G.B
SHMMAX : 2. G.B
SGA (Shared Pool ,Cache...etc) : 4 G.B
Will the instance start ??

I said:
Yes. Two Segments of 2 G.B each will be created.
He Said :
No. You are wrong. The instance won't start.

Am I wrong??
