Hi,
Find the output of the following query.
SQL> select * from v$sga;
NAME VALUE
-------------------- ----------
Fixed Size 744408
Variable Size 922746880
Database Buffers 2013265920
Redo Buffers 3420160
1. Could anyone explain me,what are the oracle memory components comes under "Fixed/Variable/Database Buffers/Redo Buffers" size calculation?
2. Does the sum of these 4 values give the total size of SGA?
Thanks...

Hi,
Are you check to total for 4 components.
lets check
SQL> show sga
Total System Global Area 209715200 bytes
Fixed Size 788168 bytes
Variable Size 145488184 bytes
Database Buffers 62914560 bytes
Redo Buffers 524288 bytes
788168+145488184+62914560+524288=209715200
