导读：1、到达最大值后自动扩展 SQL alter database datafile 'C:orcl1122disk5lianxi_index.dbf' autoextend on 2 next 2M; Database altered SQL SQL select FILE_NAME,AUTOEXTENSIBLE from dba_data_files where file_id=9; FILE_NAME AUTOEXTENSIBLE ------

1、到达最大值后自动扩展

SQL> alter database datafile 'C:orcl1122disk5lianxi_index.dbf' autoextend on
2 next 2M;
Database altered

SQL>
SQL> select FILE_NAME,AUTOEXTENSIBLE from dba_data_files where file_id=9;
FILE_NAME AUTOEXTENSIBLE
-------------------------------------------------------------------------------- --------------
C:ORCL1122DISK5LIANXI_INDEX.DBF YES

2、手工重做数据文件的大小
SQL> alter database datafile 'C:orcl1122disk5lianxi_index.dbf ' resize 25M;
Database altered

SQL> select FILE_NAME,BYTES/(1024*1024) MB from dba_data_files where file_id='9';
FILE_NAME MB
-------------------------------------------------------------------------------- ----------
C:ORCL1122DISK5LIANXI_INDEX.DBF 25

SQL>
3、添加数据文件增加表空间
SQL> alter tablespace lianxi_index add datafile 'C:ORCL1122DISK5LIANXI_INDEX02.DBF' size 15M; Tablespace altered SQL> select FILE_NAME,BYTES/(1024*1024) MB from dba_data_files where file_id>'9'; FILE_NAME MB -------------------------------------------------------------------------------- ---------- C:ORCL1122DISK5LIANXI_INDEX02.DBF 15
