    New to AIX6.1 have a Lpar system that runs two Oracle db. Total system memory is 16Gb. Current SGA size is 3Gb for each database; vendor requested increase to 8Gb for one database. From nmon it show the following available memory:

    Physical PageSpace
    % Used 72.3% 7.3%
    % Free 27.7% 92.7%
    MB Used 11844.4MB 37.4MB
    MB Free 4539.6MB 474.6MB
    Total(MB) 16384.0MB 512.0MB

    Will the Lpar system dynamically modify the amount of memory requested if all 5Gb is assigned for a total of 8Gb to this database or should only the amount of "Free" memory be assigned - 4Gb for a total of 7Gb?
