ORA-00257: archiver error的另外一种原因

今天遇到一个相对特殊的案例,拿出来和大家分享,数据库报错为不能归档ORA-00257

SQL> conn system/xxxxxx
ERROR:
ORA-00257: archiver error. Connect internal only, until freed.

SQL> archive log list;
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            /oracle/PRD/oraarch
Oldest online log sequence     11479
Current log sequence           11481

alert日志报错

sapprddb1:oraprd 73> tail -f alert_prd.log
Master archival failure: 19502
Master archival failure: 19502

Master archival failure: 19502
Master archival failure: 19502
Wed Oct 12 09:27:41 2022
Master archival failure: 19502

该错误的含义

sapprddb1:oraprd 74>oerr ora 19502
19502, 00000, "write error on file \"%s\", block number %s (block size=%s)"
// *Cause:  write error on output file
// *Action: check the file

从报错初步看是由于归档目录空间满了导致,查看发现归档空间剩余很多

sapprddb1:/oracle/PRD/sapdata1 # df -h

尝试人工归档

SQL> alter system archive log current
  2  /
alter system archive log current
*
ERROR at line 1:
ORA-19502: write error on file "/oracle/PRD/sapdata1/cntrl/cntrlPRD.dbf", block

到这里基本上明确了，由于控制文件所在的分区磁盘使用100%，导致归档的时候无法写如记录到控制文件从而导致数据库报ORA-00257错误，对/oracle/PRD/sapdata1中的某个文件进行稍微收缩，数据库恢复正常
