1.查看某个用户对应的表空间和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_fi

1.查看某个用户对应的表空间和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)临时表空间查询
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 自动管理,一般默认情况就是,如果想改为手动管理:manual
(2)临时表空间
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 :重新运用,可以加可以不加

How does MySQL handle data replication?How does MySQL handle data replication?Apr 28, 2025 am 12:25 AM

MySQL processes data replication through three modes: asynchronous, semi-synchronous and group replication. 1) Asynchronous replication performance is high but data may be lost. 2) Semi-synchronous replication improves data security but increases latency. 3) Group replication supports multi-master replication and failover, suitable for high availability requirements.

How can you use the EXPLAIN statement to analyze query performance?How can you use the EXPLAIN statement to analyze query performance?Apr 28, 2025 am 12:24 AM
