问题描述:最近巡检数据库时,发现alert日志出现ORA-00206、ORA-00202、ORA-27072告警,如下所示.
Sat Sep 24 14:47:30 2022
Errors in file /u01/app/oracle/diag/rdbms/orcl/orcl/trace/orcl_mmon_48871.trc:
ORA-00206: error in writing (block 282, # blocks 1) of control file
ORA-00202: control file: '/data/orcl/control02.ctl'
ORA-27072: File I/O error

说明:ora-00206告警并不一定标识控制文件损坏.hba 、光纤线、光纤交换机、存储连接都也会导致此异常.
