oracle sysaux表空间满了处理办法

用如下语句查询表空间

select upper(f.tablespace_name) "ts-name",

       d.tot_grootte_mb "ts-bytes(m)",

       d.tot_grootte_mb - f.total_bytes "ts-used (m)",

       f.total_bytes "ts-free(m)",

       to_char(round((d.tot_grootte_mb - f.total_bytes) / d.tot_grootte_mb * 100,

                     2),

               '990.99') "ts-per"

         from (select tablespace_name,

               round(sum(bytes) / (1024 * 1024), 2) total_bytes,

               round(max(bytes) / (1024 * 1024), 2) max_bytes

          from sys.dba_free_space

         group by tablespace_name) f,

       (select dd.tablespace_name,

               round(sum(dd.bytes) / (1024 * 1024), 2) tot_grootte_mb

          from sys.dba_data_files dd

         group by dd.tablespace_name) d

where d.tablespace_name = f.tablespace_name

order by 5 desc;
