删除临时表空间组

把在临时表空间组中所有的临时表空间剔除后，临时表空间组会自动删除：

SQL> select * from dba_tablespace_groups;

GROUP_NAME TABLESPACE_NAME

------------------------------ ------------------------------

TEMP_GROUP01 TEMP

TEMP_GROUP01 TEMP02

SQL> alter tablespace temp02 tablespace group '';

Tablespace altered.

SQL> alte tablespace temp tablespace group '';

SP2-0734: unknown command beginning "alte table..." - rest of line ignored.

SQL> alter tablespace temp tablespace group '';

Tablespace altered.

SQL> select * from dba_tablespace_groups;

no rows selected

SQL>

5）把临时表空间组设置为数据库默认的临时 表空间 组；

SQL> SELECT * FROM DBA_TABLESPACE_GROUPS;

GROUP_NAME TABLESPACE_NAME

------------------------------ ------------------------------

TEMP_GROUP01 TEMP

TEMP_GROUP01 TEMP02

SQL> ALTER DATABASE DEFAULT TEMPORARY TABLESPACE TEMP_GROUP01;
