 一、表空间管理

sys/ss as sysdba

create user sooil identified by sooil default tablespace sooil;

grant dba,connect to sooil;

create  tablespace ssyq  logging datafile  'F:appzyforadatassyqssyq.dbf' size 32000m  autoextend on  next 500m extent management local; 

ALTER TABLESPACE ssyq ADD DATAFILE 'F:appzyforadatassyqssyq2.dbf' SIZE 1000M AUTOEXTEND ON NEXT 500M MAXSIZE UNLIMITED;

ALTER TABLESPACE ssyq ADD DATAFILE 'F:appzyforadatassyqssyq3.dbf' SIZE 10000M AUTOEXTEND ON NEXT 500M MAXSIZE UNLIMITED;

drop tablespace ssyq;

alter user sooil default tablespace ssyq;

 二、空表导出设置

alter system set deferred_segment_creation=false;
