oracle 创建 temporary tablespace group

os: centos 7.4
db: oracle 12.1.0.2

oracle 可以对多个 temporary tablespace 包装成 temporary group

temporary smallfile tablespace

创建两个 temporary tablespace,在 orclpdb 下操作

CREATE TEMPORARY TABLESPACE peiyb_temp01 
TEMPFILE '/u01/app/oracle/oradata/orcl/orclpdb/peiyb_temp01.dbf' SIZE 1G AUTOEXTEND ON NEXT 1G MAXSIZE UNLIMITED
TABLESPACE GROUP ''
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 512M;

CREATE TEMPORARY TABLESPACE peiyb_temp02 
TEMPFILE '/u01/app/oracle/oradata/orcl/orclpdb/peiyb_temp02.dbf' SIZE 1G AUTOEXTEND ON NEXT 1G MAXSIZE UNLIMITED
TABLESPACE GROUP ''
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 512M;

查看 orclpdb 的 temporary tablespace

select *
from dba_tablespaces dt
where 1=1
 and dt.contents='TEMPORARY'
;

temporary tablespace group

创建 temporary group peiyb_temp_group

SQL> ALTER TABLESPACE peiyb_temp01 TABLESPACE GROUP peiyb_temp_group;
SQL> ALTER TABLESPACE peiyb_temp02 TABLESPACE GROUP peiyb_temp_group;
SQL> 
SQL> select * from dba_tablespace_groups;

GROUP_NAME		       TABLESPACE_NAME
------------------------------ ------------------------------
PEIYB_TEMP_GROUP	       PEIYB_TEMP01
PEIYB_TEMP_GROUP	       PEIYB_TEMP02

如果想从 group 中移除的话就设置为空

SQL> ALTER TABLESPACE peiyb_temp02 TABLESPACE GROUP '';

设置成 default temporary tablespace

SQL> alter pluggable database default temporary tablespace peiyb_temp_group ;

可以查看设置后的值

SQL> select * from database_properties where property_name='DEFAULT_TEMP_TABLESPACE';

这是可以移除之前的 temporary tablespace

SQL> drop tablespace temp;
