当“space=用户表空间 ”时报错处理:
--查看表空间的大小;
SQL> SELECT TABLESPACE_NAME,SUM(BYTES)/1024/1024 MB FROM DBA_FREE_SPACE GROUP BY TABLESPACE_NAME;
--查看表空间中数据文件存放的路径:
SQL> SELECT TABLESPACE_NAME, BYTES/1024/1024 FILE_SIZE_MB, FILE_NAME FROM DBA_DATA_FILES;
--错误处理:附加表空间
--alter tablespace TESTSPACE add datafile 'D:MYSPACE01.DBF' size 20480m
当“space=temp ”时报错处理:
临时表空间的作用:
临时表空间主要用途是在数据库进行排序运算[如创建索引、order by及group by、distinct、union/intersect/minus/、sort-merge及join、analyze命令]、管理索引[如创建索引、IMP进行数据导入]、访问视图等操作时提供临时的运算空间,当运算完成之后系统会自动清理。
当临时表空间不足时,表现为运算速度异常的慢,并且临时表空间迅速增长到最大空间(扩展的极限),并且一般不会自动清理了。
如果临时表空间没有设置为自动扩展,则临时表空间不够时事务执行将会报ora-01652无法扩展临时段的错误,当然解决方法也很简单:1、设置临时数据文件自动扩展,或者2、增大临时表空间。

扩展临时表空间:
方法一、增大临时文件大小:
SQL> alter database tempfile '/opt/oracle/oradata/TEST/temp01.dbf' resize 100m;
Database altered.
方法二、将临时数据文件设为自动扩展:
SQL> alter database tempfile '/opt/oracle/oradata/TEST/temp01.dbf' autoextend on next 5m maxsize unlimited;
扩展表空间时报错:
SQL> alter database tempfile '/opt/oracle/oradata/TEST/temp01.dbf' resize 100m;
alter database tempfile '/opt/oracle/oradata/TEST/temp01.dbf' resize 100m

原因是临时表空间不知道什么原因offline了,修改为online后修改成功。
