关于ORA-03002与ORA-27072错误的描述,如下所示
[oracle@DB-Server-03 ~]$ oerr ora 19502
19502, 00000, "write error on file \"%s\", blockno %s (blocksize=%s)"
// *Cause: write error on output file
// *Action: check the file
[oracle@DB-Server-03 ~]$ oerr ora 27072
27072, 00000, "File I/O error"
// *Cause: read/write/readv/writev system call returned error, additional
// information indicates starting block number of I/O
// *Action: check errno
RMAN备份出现这个错误是在生成备份集时,文件I/O发生错误,因为/u04分区空间不足导致RMAN备份无法写入数据,我们也收到了磁盘分区告警的邮件。如下所示。
