If you have Steve Adam's book, on page 82 The fixed area of SGA contains several thousand atomic variables, small data structures such as latches and pointers into other areas of the SGA. These variables are all listed in the fixed table x$ksmfsv along with their data types, sizes, and memory addresses. The variable area = large_pool_size + shared_pool_size + size of the permanent memory arrays.

What is "Variable Size" in view V$SGA, SUM(large_pool_size+java_poolsize+shared_pool_size)? 2. What is Fixed Size in view V$SGA?
