标题: 在Oracle 10g中如何解决ORA-19815错误
问题：在备份Oracle10g时出现下面的错误:

ORA-19815: WARNING: db_recovery_file_dest_size of 2147483648 bytes is 100.00% used, and has 0 remaining bytes available.

*************************************************************

You have the following choices to free up space from

flash recovery area:

1. Consider changing your RMAN retention policy.

If you are using dataguard, then consider changing your

RMAN archivelog deletion policy.

2. Backup files to tertiary device such as tape using the

RMAN command BACKUP RECOVERY AREA.

3. Add disk space and increase the db_recovery_file_dest_size

parameter to reflect the new space.

4. Delete unncessary files using the RMAN DELETE command.

If an OS command was used to delete files, then use

RMAN CROSSCHECK and DELETE EXPIRED commands.

*************************************************************

此时flash_recovery_area已经手工释放空间，甚至切换到一个全新的磁盘，但问题依然没有办法解决。

解决过程如下：

首先，连接数据库查询：

$ sqlplus "/ as sysdba"

SQL*Plus: Release 10.1.0.2.0 - Production on Mon Mar 28 11:45:30 2005

Copyright (c) 1982, 2004, Oracle. All rights reserved.

With the Partitioning, OLAP and Data Mining options

SP2-0158: unknown SET option "liesize"

SYS AS SYSDBA on 28-MAR-05 >set linesize 120

SYS AS SYSDBA on 28-MAR-05 >SELECT substr(name, 1, 30) name, space_limit AS quota,

2 space_used AS used,

3 space_reclaimable AS reclaimable,

4 number_of_files AS files

5 FROM v$recovery_file_dest ;

NAME QUOTA USED RECLAIMABLE FILES

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

/data5/flash_recovery_area 2147483648 2144863232 0 227

在此处发现仍然记录了227个文件，但USED空间并未释放。

然后用rman登录数据库进行crosscheck：

$ rman target /

此时空间得以释放:

另一个解决方法：

通过执行下面的命令将闪回区的内容备份到第三方介质：

RMAN> backup recovery area;
