Oracle导出表空间的创建语句、导入、导出dmp文件

begin
 for c in (select t.NAME ,d.NAME  as name2 from v$tablespace t
inner join  v$datafile d
on t."TS#"=d."TS#"
where t."TS#">4)
loop
dbms_output.put_line( 'create tablespace ' ||c.NAME || ' DATAFILE '||''''||c.name2||''''||' size 20M
AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED;' );
end loop;
end;

结果如：

create tablespace EXAMPLE DATAFILE 'D:\ORACLE\ORADATA\ORCL\EXAMPLE01.DBF' size 20M
AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED;
create tablespace HCZZ_WEB_DATA DATAFILE 'D:\ORACLE\ORADATA\ORCL\DBF_HCZZ_WEB_DATA.DBF' size 20M
AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED;
create tablespace HCZZ_WEB_INDEX DATAFILE 'D:\ORACLE\ORADATA\ORCL\DBF_HCZZ_WEB_INDEX.DBF' size 20M
AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED;

数据库导出：

--第一次新建数据库导入使用
impdp hczz_web/password@localhost/orcl dumpfile=HCZZ_WEB_20170706.dmp
impdp hczz_web/password@221.234.25.77/orcl dumpfile=HCZZ_WEB_20180502.dmp
impdp hczz_web/password dumpfile=HCZZ_WEB_20170706.dmp
--第二次导入使用
impdp hczz_web/password dumpfile=HCZZ_WEB_20170706.dmp table_exists_action=replace
--如果有替换还原新的数据库命，则执行----------------------
impdp hczz_web_test1/password@localhost/orcl dumpfile=HCZZ_WEB_20170628.DMP table_exists_action=replace remap_schema=hczz_web:hczz_web_test1
impdp hczz_web_test1/password@localhost/orcl dumpfile=HCZZ_WEB_20170628.DMP table_exists_action=replace remap_schema=hczz_web:hczz_web_test1
impdp hczz_web_test1/password@localhost/orcl dumpfile=备份库.DMP table_exists_action=replace remap_schema=原库名:现库名

创建表空间

/*分为四步 */
/*第1步：创建临时表空间  */
create temporary tablespace yuhang_temp 
tempfile 'D:\oracledata\yuhang_temp.dbf' 
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;  
 
/*第2步：创建数据表空间  */
create tablespace yuhang_data  
logging  
datafile 'D:\oracledata\yuhang_data.dbf' 
size 50m  
autoextend on  
next 50m maxsize 20480m  
extent management local;  
 
/*第3步：创建用户并指定表空间  */
create user yuhang identified by yuhang  
default tablespace yuhang_data  
temporary tablespace yuhang_temp;  
 
/*第4步：给用户授予权限  */
grant connect,resource,dba to yuhang;

创建用户

DECLARE
   user_name              CONSTANT VARCHAR2 (64) := 'hczz_web';
   user_password          CONSTANT VARCHAR2 (64) := 'password';
   data_tablespace_name   CONSTANT VARCHAR2 (64) := 'hczz_web_data';
   temp_tablespace_name   CONSTANT VARCHAR2 (64) := 'hczz_web_temp';

   PROCEDURE p_execcmd (v_cmd IN VARCHAR2)
   AS
      v_cursorid   INTEGER;
   BEGIN
      v_cursorid := DBMS_SQL.open_cursor;
      DBMS_SQL.parse (v_cursorid, v_cmd, DBMS_SQL.native);
      DBMS_SQL.close_cursor (v_cursorid);
   EXCEPTION
      WHEN OTHERS
      THEN
         DBMS_SQL.close_cursor (v_cursorid);
         RAISE;
   END p_execcmd;
BEGIN
-------------------1.创建用户-----------------------------------------------
   p_execcmd (   'CREATE USER '
              || user_name
              || ' PROFILE DEFAULT IDENTIFIED BY '
              || user_password
              || ' DEFAULT TABLESPACE '
              || data_tablespace_name
              || ' TEMPORARY TABLESPACE '
              || temp_tablespace_name
              || ' ACCOUNT UNLOCK'
             );
-------------------2.授权---------------------------------------------------

 p_execcmd(  'GRANT CONNECT TO '||user_name||' WITH ADMIN OPTION' );

 p_execcmd(  'GRANT RESOURCE TO '||user_name||' WITH ADMIN OPTION'   );

---以下慎用，权限过大
 p_execcmd(  'GRANT DBA TO '||user_name||' WITH ADMIN OPTION'  );
END;
