故障现象
执行SELECT tablespace_name 表空间,sum(blocks*8192/1000000) 剩余空间M FROM dba_free_space GROUP BY tablespace_name;
报如下错误
ORA-01116: error in opening database file 47
ORA-01110: data file 47: '/dev/rpt_itrusca_disk'
ORA-27041: unable to open file
IBM AIX RISC System/6000 Error: 13: Permission denied

故障分析
根据Permission denied怀疑是权限问题，如下查询得知果然权限crw-rw----和其他空间不一样
p550a:/dev#ls -lt|grep rpt_
crw-rw---- 1 root system 80,100 8月09 17时39 rpt_itrusca_disk

解决
chmod 后故障消失
p550a:/dev#chmod 777 rpt_itrusca_disk
后续规范解决:chown oracle:dba rpt_itrusca_disk
