--查看表空间目录： select * from dba_data_files where tablespace_name = 'SYSAUX'; --2.查看表空间使用率： select a.tablespace_name,a.bytes/1024/1024 "Sum MB",(a.bytes-b.bytes)/1024/1024 "used MB",b.bytes/1024/1024 "free MB",round(((a.bytes-b.bytes)/a.bytes)*100,2) "percent_used" from (select tablespace_name,sum(bytes) bytes from dba_data_files group by tablespace_name) a, (select tablespace_name,sum(bytes) bytes,max(bytes) largest from dba_free_space group by tablespace_name) b where a.tablespace_name=b.tablespace_name order by ((a.bytes-b.bytes)/a.bytes) desc
--3. 增加表空间大小： alter tablespace SYSAUX add datafile 'D:\ORACLEDATA\ORCL\SYSAUX03.DBF' size 2048M;
