創建用戶：
1，sqlplus sys/pwd as sysdba;
2, create user
username identified by
password;
3, grant dba,connect,resource to
username;
查看表空間使用情況：
SELECT UPPER(F.TABLESPACE_NAME) "表空間名",
D.TOT_GROOTTE_MB "表空間大小(M)",
D.TOT_GROOTTE_MB - F.TOTAL_BYTES "已使用空間(M)",
TO_CHAR(ROUND((D.TOT_GROOTTE_MB - F.TOTAL_BYTES) / D.TOT_GROOTTE_MB * 100,2),'990.99') || '%' "使用比",
F.TOTAL_BYTES "空閑空間(M)",
F.MAX_BYTES "最大塊(M)"
FROM (SELECT TABLESPACE_NAME,
ROUND(SUM(BYTES) / (1024 * 1024), 2) TOTAL_BYTES,
ROUND(MAX(BYTES) / (1024 * 1024), 2) MAX_BYTES
FROM SYS.DBA_FREE_SPACE
GROUP BY TABLESPACE_NAME) F,
(SELECT DD.TABLESPACE_NAME,
ROUND(SUM(DD.BYTES) / (1024 * 1024), 2) TOT_GROOTTE_MB
FROM SYS.DBA_DATA_FILES DD
GROUP BY DD.TABLESPACE_NAME) D
WHERE D.TABLESPACE_NAME = F.TABLESPACE_NAME
ORDER BY 1;
exp導出dmp文件：
EXP SYSTEM/MANAGER BUFFER=64000 FILE=D:\FULL.DMP FULL=Y
IMP SYSTEM/MANAGER BUFFER=64000 FILE=D:\FULL.DMP FULL=Y
imp指定表空間：
1.創建表空間
create tablespace
example_tablespace datafile 'D:\****.dmp' size 1024m
reuse
autoextend on
next 4m maxsize unlimited;
2.創建用戶，指定表空間，臨時表空間
create user
username identified by
password default tablespace
example_tablespace temporary tablespace
temp;
3.IMP導入數據庫文件注意
grant dba to
username;
DBA權限是必需的
一般默認導入的表空間是導出時候的表空間
revoke unlimited tablespace from
username;// 撤銷此權限
alter user
username quota 0 on
users; // 將用戶在
users 表空間的配額置為 0
alter user
username quota unlimited on
example_tablespace;// 設置在用戶在
example_tablespace表空間配額不受限。
imp
username/
password file='D:\***.dmp' tablespaces=
example_tablespace log='D:\imp_log.txt'
