一、creating a database
1、以系統管理員使用者登入。
$ sqlplus / as sysdba
2、啟動資料庫導nomount狀態。
sql> startup nomount;
3、執行建立資料庫語句。
sql> create database invrep controlfile reuse
maxlogfiles 16
maxlogmembers 4
maxdatafiles 1024
maxinstances 1
maxloghistory 680
character set "utf8"
logfile group 1
('/ora01/oradata/invrep/redo01a.log',
'/ora01/oradata/invrep/redo01b.log') size 200m reuse,
group 2
('/ora01/oradata/invrep/redo02a.log',
'/ora01/oradata/invrep/redo02b.log' ) size 200m reuse,
group 3
('/ora01/oradata/invrep/redo03a.log',
'/ora01/oradata/invrep/redo03b.log' ) size 200m reuse
datafile
'/ora01/oradata/invrep/system01.dbf'
size 500m
reuse
undo tablespace undotbs1 datafile
'/ora01/oradata/invrep/undotbs01.dbf'
size 800m
reuse
sysaux datafile
'/ora01/oradata/invrep/sysaux01.dbf'
size 200m
reuse
default temporary tablespace temp tempfile
'/ora01/oradata/invrep/temp01.dbf'
size 800m
reuse;
4、執行這兩個語句，生成資料字典。
sql> @?/rdbms/admin/catalog.sql
sql> @?/rdbms/admin/catproc.sql
5、執行這個過程，建立通用同義詞，供別的使用者訪問系統表。
sql> connect system/manager
sql> @?/sqlplus/admin/pupbld.sql
二、dropping a database
1、select name from v$database;
2、shutdown immediate;
3、startup mount exclusive restrict;
4、drop database;
三、檢視連線資訊
sql>select name from v$database;
sql> show user;
四、creating tablespace
create tablespace inv_data
datafile '/ora02/rmdb11/invdata01.dbf'
size 100m
extent management local
uniform size 256k
segment space management auto;
五、dropping a tablespace
alter tablespace inv_data offline;
drop tablespace inv_data including contents and datafiles;
六、調整表空間大小
1、select name, bytes from v$datafile;
2.1、alter database datafile '/ora01/oradata/invrep/reg_data01.dbf' resize 1g;
2.2、alter tablespace reg_data add datafile '/ora01/oradata/invrep/reg_data02.dbf' size 100m;
2.3、alter database datafile '/ora01/oradata/invrep/reg_data02.dbf' autoextend on maxsize 1000m;
3、select name, bytes from v$tempfile;
3.1、alter database tempfile '/ora01/oradata/invrep/temp01.dbf' resize 500m;
3.2、alter tablespace temp add tempfile '/ora01/oradata/invrep/temp02.dbf' size 5000m;
七、限制每個使用者訪問的資料資源數目。
1、create profile user_profile_limit
limit
sessions_per_user 20
cpu_per_session 240000
logical_reads_per_session 1000000
connect_time 480
idle_time 120;
2、 alter user heera profile user_profile_limit;
3、select name, value from v$parameter where name='resource_limit';
八、建立許可權組。(role)
create role jr_dba;
grant select any table to jr_dba;
grant create any table to jr_dba;
grant create any view to jr_dba;
grant create synonym to jr_dba;
grant create database link to jr_dba;
grant jr_dba to lellison;
grant jr_dba to cphillips;
select grantee, granted_role from dba_role_privs order by 1;
select * from user_role_privs;
revoke create database link from jr_dba;
revoke jr_dba from lellison;
九、建立使用者
create user heera identified by chaya
default tablespace users
temporary tablespace temp;
grant create session to heera;
grant create table to heera;
alter user heera quota unlimited on users;
十、使用者管理
drop user heera cascade;
alter user heera account lock;
select username, lock_date from dba_users;
alter user heera account unlock;
十一、修改使用者密碼
alter user heera identified by foobar;
