rman 备份中ORA-19809、ORA-19804问题解决
在我的测试环境中使用rman备份数据库的时候，报如下错误（红色部分）：

这是flash_recovery_area空间不足的提示
[@more@]用如下方法检查flash_recovery_area使用情况
| oracle@oracle[/oracle]> sqlplus / as sysdba SQL*Plus: Release 10.2.0.1.0 - Production on Sat Jan 9 09:44:30 2010 Copyright (c) 1982, 2005, Oracle. All rights reserved.

检查db_recovery_file_dest_size参数
| sys@CNHTM> show parameter recovery NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ db_recovery_file_dest string /oracle/flash_recovery_area db_recovery_file_dest_size big integer 1G recovery_parallelism integer 0 |
将参数db_recovery_file_dest_size增大为20G

再次备份，没有问题了
