Oracle解决ora-01653 无法通过1024扩展

1.oracle查询表空间是否已满

select dbf.tablespace_name,
dbf.totalspace "总量(M)",
dbf.totalblocks as 总块数,
dfs.freespace "剩余总量(M)",
dfs.freeblocks "剩余块数",
(dfs.freespace / dbf.totalspace) * 100 "空闲比例"
from (select t.tablespace_name,
sum(t.bytes) / 1024 / 1024 totalspace,
sum(t.blocks) totalblocks
from dba_data_files t
group by t.tablespace_name) dbf,
(select tt.tablespace_name,
sum(tt.bytes) / 1024 / 1024 freespace,
sum(tt.blocks) freeblocks
from dba_free_space tt
group by tt.tablespace_name) dfs
where trim(dbf.tablespace_name) = trim(dfs.tablespace_name)；

或者使用

SELECT Total.name "Tablespace Name",
Free_space,
(total_space - Free_space) Used_space,
total_space
FROM (select tablespace_name, sum(bytes / 1024 / 1024) Free_Space
from sys.dba_free_space
group by tablespace_name) Free,
(select b.name, sum(bytes / 1024 / 1024) TOTAL_SPACE
from sys.v_$datafile a, sys.v_$tablespace B
where a.ts# = b.ts#
group by b.name) Total
WHERE Free.Tablespace_name = Total.name;

2.再查看表空间是否开启了自动扩展的功能 

SELECT T.TABLESPACE_NAME,
D.FILE_NAME,
D.AUTOEXTENSIBLE,
D.BYTES,
D.MAXBYTES,
D.STATUS
FROM DBA_TABLESPACES T, DBA_DATA_FILES D
WHERE T.TABLESPACE_NAME = D.TABLESPACE_NAME
ORDER BY TABLESPACE_NAME, FILE_NAME;

从上表可以看出，所有的表空间都开启了自动扩展的功能，而且状态都是available的；

综合上述检查结果，可断定遇到的问题是因为可能性1—表空间不足导致。解决办法也就是扩大表空间

扩大表空间的四种方法： 
1、增加数据文件 
ALTER TABLESPACE ***_TRD ADD DATAFILE 
‘D:OraclePRODUCT10.2.0ORADATADBFILETRD_2.DBF’ SIZE 1024M;

2、增加数据文件并允许自动增长 
ALTER TABLESPACE ***_TRD ADD DATAFILE 
‘D:ORACLEPRODUCT10.2.0ORADATADBFILETRD_2.DBF’ SIZE 1024M AUTOEXTEND ON NEXT 8M MAXSIZE 10240M;

3、允许已存在的数据文件自动增长 
ALTER DATABASE DATAFILE ‘D:ORACLEPRODUCT10.2.0ORADATADBFILETRD.DBF’ 
AUTOEXTEND ON NEXT 8M MAXSIZE 10240M;

4、手工改变已存在数据文件的大小 
ALTER DATABASE DATAFILE ‘D:ORACLEPRODUCT10.2.0ORADATADBFILETRD.DBF’ 
RESIZE 10240M;

实际解决过程中，我们使用的是方法2。
