1.查询表空间信息
select tablespace_name,file_name,bytes/1024/1024 mb from dba_temp_files
union all
select tablespace_name,file_name,bytes/1024/1024 mb from dba_data_files;
------------------------------------------------------------------------------------------------------
1 TEMP /u02/oradata/DB112/temp01.dbf 29
2 USERS /u02/oradata/DB112/users01.dbf 5
3 UNDOTBS1 /u02/oradata/DB112/undotbs01.dbf 75
4 SYSAUX /u02/oradata/DB112/sysaux01.dbf 510
5 SYSTEM /u02/oradata/DB112/system01.dbf 740
2.UNDO梳理
#此处为测试环境故设置100M，生产环境要放大10G以上
SQL> ALTER DATABASE DATAFILE ‘/u02/oradata/DB112/undotbs01.dbf‘ RESIZE 100M;
SQL> ALTER DATABASE DATAFILE ‘/u02/oradata/DB112/undotbs01.dbf‘ AUTOEXTEND ON NEXT 50M;
3.TEMP 梳理
#此处为测试环境故设置100M，生产环境要放大10G以上
CREATE TEMPORARY TABLESPACE TEMP1 TEMPFILE
‘/u02/oradata/DB112/TEMP1_1.dbf‘ SIZE 256M REUSE AUTOEXTEND ON NEXT 128M MAXSIZE 1G,
‘/u02/oradata/DB112/TEMP1_2.dbf‘ SIZE 256M REUSE AUTOEXTEND ON NEXT 128M MAXSIZE 1G
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1M;
ALTER TABLESPACE TEMP1 TABLESPACE GROUP TEMP_GP;
ALTER DATABASE DEFAULT TEMPORARY TABLESPACE TEMP_GP;
#如无法删除则需重启db
drop tablespace TEMP including contents and datafiles;
select * from dba_tablespace_groups;
4.整理用户表空间
create tablespace MY_UD datafile
‘/u02/oradata/DB112/MY_UD1.dbf‘ size 128M AUTOEXTEND ON NEXT 64M MAXSIZE UNLIMITED,
‘/u02/oradata/DB112/MY_UD2.dbf‘ size 128M AUTOEXTEND ON NEXT 64M MAXSIZE UNLIMITED
default storage (initial 128K next 2M pctincrease 0);
Create tablespace I_MY_UD datafile
‘/u02/oradata/DB112/I_MY_UD1.dbf‘ size 64M AUTOEXTEND ON NEXT 32M MAXSIZE UNLIMITED,
‘/u02/oradata/DB112/I_MY_UD2.dbf‘ size 64M AUTOEXTEND ON NEXT 32M MAXSIZE UNLIMITED
default storage (initial 128K next 2M pctincrease 0);
ALTER DATABASE DEFAULT TABLESPACE MY_UD;
drop tablespace USERS including contents and datafiles;
select tablespace_name,file_name,bytes/1024/1024 mb from dba_temp_files
union all
select tablespace_name,file_name,bytes/1024/1024 mb from dba_data_files;
------------------------------------------------------------------------------------------------------
1 TEMP1 /u02/oradata/DB112/TEMP1_1.dbf 128
2 TEMP1 /u02/oradata/DB112/TEMP1_2.dbf 128
3 UNDOTBS1 /u02/oradata/DB112/undotbs01.dbf 100
4 SYSAUX /u02/oradata/DB112/sysaux01.dbf 510
5 SYSTEM /u02/oradata/DB112/system01.dbf 740
6 MY_UD /u02/oradata/DB112/MY_UD1.dbf 128
7 MY_UD /u02/oradata/DB112/MY_UD2.dbf 128
8 I_MY_UD /u02/oradata/DB112/I_MY_UD1.dbf 64
9 I_MY_UD /u02/oradata/DB112/I_MY_UD2.dbf 64
5.创建新用户
CREATE USER XAG IDENTIFIED BY "123456" DEFAULT TABLESPACE MY_UD TEMPORARY TABLESPACE TEMP_GP;
GRANT DBA to XAG;
grant connect,resource,unlimited tablespace to XAG;
grant create any directory to XAG;
grant drop any directory to XAG;
#修改密码(可选)
alter user XAG identified by "xag123";
#账户锁定后解锁命令(可选) sys or system
alter user XAG account unlock;
#设置用户密码无限次尝试登录
alter profile default limit failed_login_attempts unlimited;
#设置用户密码不过期：
alter profile default limit password_life_time unlimited;
#查看配置的参数
select profile,RESOURCE_NAME,resource_type,limit from dba_profiles where
RESOURCE_NAME in(‘FAILED_LOGIN_ATTEMPTS‘,‘PASSWORD_LIFE_TIME‘) and profile=‘DEFAULT‘;
6.創建測試自動插入job(xag用户下)
begin
dbms_network_acl_admin.create_acl
(
acl => ‘utl_http.xml‘, -- 文件名称
description => ‘HTTP Access‘, -- 描述
principal => ‘XAG‘, -- 授权或者取消授权账号，大小写敏感
is_grant => TRUE, -- 授权还是取消授权
privilege => ‘connect‘, -- 授权或者取消授权的权限列表
start_date => null, -- 起始日期
end_date => null -- 结束日期
);
end;
begin
dbms_network_acl_admin.add_privilege ( -- 添加访问权限列表项
acl => ‘utl_http.xml‘, -- 刚才创建的acl名称
principal => ‘XAG‘, -- 授权或取消授权用户
is_grant => TRUE, -- 与上同
privilege => ‘resolve‘, -- 权限列表
start_date => null,
end_date => null
);
end;
begin
dbms_network_acl_admin.assign_acl(acl => ‘utl_http.xml‘, host =>‘*‘);
end;
create table my_healt_check
as
select utl_inaddr.get_host_address as host_address
,utl_inaddr.get_host_name as host_name
,sys_context(‘USERENV‘,‘DB_NAME‘) as db_name
,sysdate as create_time from dual;
create or replace procedure pr_my_healt_check_insert as
begin
delete from my_healt_check a where a.create_time<sysdate-1/24;
insert into my_healt_check(host_address,host_name,db_name,create_time)
select utl_inaddr.get_host_address,utl_inaddr.get_host_name,sys_context(‘USERENV‘,‘DB_NAME‘),sysdate from dual;
commit;
end;
Declare job1 Number;
Begin
dbms_job.submit(job1,‘pr_my_healt_check_insert;‘,Sysdate,‘sysdate + (1/(24*60))‘);
Commit;
End;
or
declare
v_count int := 0;
begin
select count(*) into v_count from user_scheduler_jobs where job_name=‘TEST_JOB1‘;
if v_count > 0 then
dbms_scheduler.drop_job(‘HEALT_CHECK‘);
end if;
dbms_scheduler.create_job (
job_name => ‘healt_check‘,
job_type => ‘STORED_PROCEDURE‘,
job_action => ‘pr_my_healt_check_insert‘,
start_date => sysdate,

end;
