ORA-19809: limit exceeded for recovery files

ORA-19809: limit exceeded for recovery files

闪回区空间耗尽，且归档路径设置到了闪回恢复区中，则由于日志无法归档，数据库会hang住。数据库关闭不成功，重启后，再次启动，报错为

ORA-16038: log 3 sequence# 46 cannot be archived
ORA-19809: limit exceeded for recovery files
ORA-00312: online log 3 thread 1: '/oratest/redo/redo03.log'

如：

SQL> startup

instance started.

ORA-19809: limit exceeded for recovery files
ORA-00312: online log 3 thread 1: '/oratest/redo/redo03.log'

处理方法为：扩大闪回恢复空间大小

SQL> ALTER SYSTEM SET db_recovery_file_dest_size=3g SCOPE=BOTH;

System altered.

SQL> alter database open;

Database altered.

SQL>

通过查询视图v$flash_recovery_area_usage，可以获得当前闪回恢复区的空间使用情况，并且可以知道是哪些文件占中了空间，据此可以做出相应的处理，或者加大闪回恢复区，或者移走相应的文件。

SQL> select * from v$recovery_file_dest;
