ORA-19809: limit exceeded for recovery files问题解决

今天查看数据库[/u]管理[/u]器出错日志oradim.log
发现如下报警信息：

ORA-16038: log 3 sequence# 472 cannot be archived

ORA-19809: limit exceeded for recovery files

ORA-00312: online log 3 thread 1: 'C:\ORACLE\PRODUCT\10.2.0\ORADATA\CHEP\REDO03.LOG'

查了一下错误信息

ORA-19809: limit exceeded for recovery files

Cause: The limit for recovery files specified by the DB_RECOVERY_FILE_DEST_SIZE was exceeded.

Action: The error is accompanied by 19804. See message 19804 for further details.

oracle10g在默认情况下，归档日志是保存在闪回恢复区的，如果你建库的时候用的默认设置，

闪回恢复区应该是2G，空间被占满了以后就无法再归档了

你可以用下面的命令查看其大小和存储位置

SQL> show parameter db_recovery_file_dest;

NAME TYPE VALUE

------------------------------------ ----------- ------------------------------

db_recovery_file_dest string C:\oracle\product\10.2.0/flash_recovery_area

db_recovery_file_dest_size big integer 2G

解决方法：

1.增大闪回恢复区。

su - oracle;

sqlplus /nolog;

connect / as sysdba;

startup unmount;

ALTER SYSTEM SET db_recovery_file_dest_size=4g scope=both;

startup;

2.将归档设置到其他目录，修改alter system set log_archive_dest = 其他路径

可事先用show parameter log_archive_dest查看

3.转移或者删除闪回恢复区里的归档日志。
