Oracle增加数据文件(表空间无法扩展)
现象报错:java.sql.SQLException: ORA-01654: unable to extend index table_student by 8192 in tablespace SF_INDEX
一、表空间处理:
1、查看现有情况
select file_name,tablespace_name,autoextensible from dba_data_files where TABLESPACE_NAME='SF_INDEX';
2、增加数据文件
alter tablespace SF_INDEX add datafile '+ORADATA/PRO_BUSINESS/DATAFILE/sf_index9.dbf' size 100M autoextend on next 100M maxsize UNLIMITED;
二、临时表空间处理
1、查看现有情况
select tablespace_name,
file_name,
user_bytes/bytes,
bytes / 1024 / 1024 "file_size(M)",
autoextensible
from dba_temp_files t
where t.TABLESPACE_NAME = 'TEMP';
或
select c.tablespace_name,
to_char(c.bytes/1024/1024/1024,'99,999.999') total_gb,
to_char( (c.bytes-d.bytes_used)/1024/1024/1024,'99,999.999') free_gb,
to_char(d.bytes_used/1024/1024/1024,'99,999.999') use_gb,
to_char(d.bytes_used*100/c.bytes,'99.99') || '%'use
from (select tablespace_name,sum(bytes) bytes
from dba_temp_files GROUP by tablespace_name) c,
(select tablespace_name,sum(bytes_cached) bytes_used
from v$temp_extent_pool GROUP by tablespace_name) d
where c.tablespace_name = d.tablespace_name;
2、增加数据文件
alter TABLESPACE TEMP ADD TEMPFILE '+ORADATA/PRO_BUSINESS/TEMPFILE/temp5.dbf' SIZE 1G AUTOEXTEND ON NEXT 128M MAXSIZE UNLIMITED;
