大家好，又见面了，我是全栈君。
1.查看某个用户相应的表空间和datafile
select t1.username,t2.tablespace_name,t2.file_name,t1.temporary_tablespace ,t3.file_name
from dba_users t1
left join
dba_data_files t2
on t1.default_tablespace = t2.tablespace_name
left join
dba_temp_files t3
on t1.temporary_tablespace = t3.tablespace_name
where
lower(t1.username) in
(‘lbi_sys_ptcl’,’lbi_ods_ptcl’,’lbi_ods_ptcl’,’lbi_edm_ptcl’,’lbi_ls_ptcl’,’lbi_dm_ptcl’,’lbi_dim_ptcl’)
2.产看表空间信息：
（1）一般表空间查询
select * from dba_data_files t where t.tablespace_name in (
‘TBS_DIM_PTCL’,’TBS_LS_PTCL’, ‘TBS_ODS_PTCL’, ‘TBS_DM_PTCL’, ‘TBS_EDM_PTCL’, ‘TBS_SYS_PTCL’ );
（2）暂时表空间查询
select * from dba_temp_files t where t.tablespace_name in (‘TBS_TEMP_PTCL’);
3.创建表空间
(1)一般表空间
create tablespace “TBS_DW_YM”
nologging
datafile ‘/opt/oracle/oradata/YM_tbs/TBS_DW_YM.dbf’ size 50m
extent management local segment space management auto;
–extent management:区管理
–local segment space management :本地段空间管理
–auto 自己主动管理,一般默认情况就是,假设想改为手动管理：manual
(2)暂时表空间
create
temporary tablespace “TBS_YM_TEMP”
tempfile ‘/opt/oracle/oradata/YM_tbs/TBS_YM_TEMP.dbf’ size 50m
reuse autoextend on next 640k maxsize 1000M;
–reuse :又一次运用,能够加能够不加
