In Oracle 10 Gb system management, there is an automatic SGA memory management ASMM ). This function is described as follows:
To use automatic management, you need to set the parameters SGA_TARGET, STATISTICS_LEVEL = TYPICAL or ALL. Because the statistics set is not supported, the database does not have the necessary historical information to determine the size ). In Oracle9i and earlier versions, you can only use manual SGA memory management. The SGA
