今天用RMAN做全库备份出现错误：
channel ORA_DISK_1: starting piece 1 at 04-FEB-09

Errors in file /u01/app/oracle/admin/jarod/udump/jarod_ora_1964.trc:
ORA-19815: WARNING: db_recovery_file_dest_size of 2147483648 bytes is 100.00% used, and has 0 remaining bytes available.
************************************************************************
You have following choices to free up space from flash recovery area:
1. Consider changing RMAN RETENTION POLICY. If you are using Data Guard,
then consider changing RMAN ARCHIVELOG DELETION POLICY.
2. Back up files to tertiary device such as tape using RMAN
BACKUP RECOVERY AREA command.
3. Add disk space and increase db_recovery_file_dest_size parameter to
reflect the new space.
4. Delete unnecessary files using RMAN DELETE command. If an operating
system command was used to delete files, then use RMAN CROSSCHECK and
DELETE EXPIRED commands.
问题是在db_recovery_file_dest_size 备份时没有足够的空间造成的
为db_recovery_file_dest_size 添加空间：
alter system set db_recovery_file_dest_size=10G scope=both;
