oracle 11g中 內存用了自動化管理

MEMORY_TARGET的值大於/dev/shm 就會報錯 ORA-00845: MEMORY_TARGET not supported on this system錯誤,

redhat系列系統中，/dev/shm的默認值是系統總內存的一半

alter system set memory_max_target=1024M scope=spfile;

alter system set memory_target=1024M scop=spfile;

alter system set sga_target=0 scope=spfile;

alter system set sga_max_size=0 scope=spfile;

alter system set pga_aggregate_target=0 scope=spfie;

--查看sga

show parameter sga;

--查看實際pga

select * from v$pgastat
