    Oracle 数据结构部署

    用例:

    • - 1、查询DBF文件位置
      select tablespace_name, file_id,file_name, round(bytes/(1024*1024),0) total_space from dba_data_files order by tablespace_name;
      select * from dba_data_files;
      --/home/oracle/app/oracle/oradata/orcl/users01.dbf




    • - 2、删除用户表空间
      drop user ecom cascade;
      drop tablespace ERPDATA including contents and datafiles;
    
    • - 3、创建表空间
      create tablespace ERPDATA datafile 'D:/test/ecom_00.dbf' size 200M;
    
    • - 4、授权表空间大小自增长
      alter database datafile 'D:/test/ecom_00.dbf' AUTOEXTEND ON NEXT 100M MAXSIZE 3000M;
      alter tablespace ERPDATA add datafile '/data/oracle/data/orcl/ecom_01.dbf' size 200M;
      alter database datafile '/data/oracle/data/orcl/ecom_01.dbf' AUTOEXTEND ON NEXT 100M MAXSIZE 3000M;
    
    • - 5、扩展空间,将数据文件扩大至5000MB
      alter database datafile '/data/oracle/data/orcl/ecom_01.dbf' resize 5000m;
    
    • - 6、创建用户
      create user ecom identified by "passwd111" account unlock default tablespace ERPDATA;
    
    • - 7、给用户授权
      grant "CONNECT" TO ecom;
      grant resource to ecom;
      grant "JAVASYSPRIV" TO ecom;
      grant "JAVAUSERPRIV" TO ecom;
      grant create view to ecom;
      grant create synonym to ecom;
    

    操作点:

    • --当前用户有多少张表

    select count(table_name) from user_tables ;

    • --用户在表空间所分配的空间没有限制

    alter user sourcedata quota unlimited on SRC_DATA;

    • /* 无法删除当前连接用户

    select username ,sid,serial# from v$session
    alter system kill session '687,4263';
    alter system kill session '491,34491';

    • --查询用户权限

    select * from dba_sys_privs d where d.GRANTEE = 'ECOM';

    • --查询用户对表的权限

    select 'grant '||u.privilege||' on '||u.TABLE_NAME||' to '||u.GRANTEE||' with grant option;'
    from user_tab_privs u where u.table_name not like '%==%';
    --撤销授权不级联
    with admin option;
    --撤销授权级联
    with grant option;
