----查询某表空间下的对象的情况，比如大小
select SEGMENT_NAME,bytes/1024/1024  big from dba_segments
where TABLESPACE_NAME='TEMP_TABLE'
order by big asc

----查询临时表空间采用的是哪些表空间？
select * from dba_temp_files;

col username format a20
col DEFAULT_TABLESPACE format a20
col TEMPORARY_TABLESPACE format a10
col CREATED format a20
select USERNAME,DEFAULT_TABLESPACE,TEMPORARY_TABLESPACE,created from dba_users; 

----创建临时表空间
SQL>  create temporary tablespace aa
tempfile 'c:/life/temp.dbf' size 500m
extent management local ;

SQL> alter database default
temporary tablespace aa;

SQL> select  tablespace_name from dba_temp_files;

修改表空间大小：

i3db数据库表空间：
SYMANTEC_I3_PW_80_IND_LARGE
SYMANTEC_I3_PW_80_IND_SMALL空间不足告警，为了缓解当前表空间的应用，以下操作。
一、压缩表和索引：
对所有非分区的表和该表上的索引进行了compress操作

首先查询出表空间中所有的表：
select owner,segment_name,segment_type,bytes/1024/1024 from dba_segments where tablespace_name='SYMANTEC_I3_PW_80_TAB_LARGE';
select owner,segment_name,segment_type,bytes/1024/1024 from dba_segments where tablespace_name='SYMANTEC_I3_PW_80_TAB_SMALL';

然后对segment_type的为table的对象进行压缩：
alter table VERITAS. PS_ORSM_SCHEMA_CHANGE_LOG move compress parallel 8 nologging;

查询出table上的索引：
select * from dba_indexes where table_name='PW_OSSS_SRV_STATISTICS_B';

再对索引进行压缩：
alter index VERITAS.IS_OSSS_NUM_CP04_B rebuild compress nologging;
alter index VERITAS.IS_OSSS_TOT_PH05_B rebuild compress nologging;
alter index VERITAS.IS_OSSS_TOT_VI06_B rebuild compress nologging;
alter index VERITAS.IS_OSSS_INSTANCE23_B rebuild compress nologging;

由于在压缩过程中报临时表空间不足，征求意见过后，将临时表空间TEMPTS1原先的2G扩展到3G。
alter tablespace TEMPTS1 add tempfile '/i3data/oradata/datafile/temp02.dbf' size 1024M autoextend off;

二、挪动索引到其它表空间

select owner,segment_name,segment_type,bytes/1024/1024 from dba_segments where tablespace_name='SYMANTEC_I3_PW_80_IND_SMALL'
order by BYTES desc

经过查询，确认对索引IW_TUAC_01_T做rebuild到其它表空间的操作,索引IW_TUAC_01_T大小为2G
而SYMANTEC_I3_PW_80_IND_MEDIUM相对充裕，即打算将原来属于表空间IND_SMALL的索引IW_TUAC_01_T挪到表空间IND_MEDIUM，
以缓解表空间IND_SMALL的使用压力。

SQL> ALTER INDEX VERITAS.IW_TUAC_01_T REBUILD SUBPARTITION P12052008_19052008_S1084 TABLESPACE SYMANTEC_I3_PW_80_IND_MEDIUM;
 
Index altered

SQL>select index_name,status,tablespace_name from dba_ind_subpartitions where index_name='IW_TUAC_01_T'

INDEX_NAME               STATUS          TABLESPACE_NAME
-------------------- ----------------------- -----------------------------------------------
IW_TUAC_01_T USABLE   SYMANTEC_I3_PW_80_IND_MEDIUM 
IW_TUAC_01_T USABLE   SYMANTEC_I3_PW_80_IND_MEDIUM 
IW_TUAC_01_T USABLE   SYMANTEC_I3_PW_80_IND_MEDIUM
