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

************************************************************************
--附录：关于scope=both的说明：
Question: I don't understand the scope=memory option. Does scope=memory only apply to SGA parameters?
How is scope=memory different than a standard alter system command?
Answer: scope is a parameter used in conjunction with the alter system command when you are changing any initialization parameter of an spfile.
It is vital to understand how to use this parameter to achieve the desired effect.
There are three values that the scope parameter can take:
scope = memory
scope = spfile
scope = both
For the value in question, scope = memory, Oracle will make the change specified by the alter system command for the life of the instance.
The next time the database is bounced, for any reason, the change will be reverted to the default value.
For scope=spfile the change made in the alter system command will take place starting from the next startup but will not affect the current instance.
If you want the alter system command to take place immediately you can use the scope = both value, which will make the change for the current instance and preserve it through any future bounces.'

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

--附录：关于scope=both的说明：
Question: I don't understand the scope=memory option. Does scope=memory only apply to SGA parameters?
How is scope=memory different than a standard alter system command?
Answer: scope is a parameter used in conjunction with the alter system command when you are changing any initialization parameter of an spfile.
It is vital to understand how to use this parameter to achieve the desired effect.
There are three values that the scope parameter can take:
scope = memory
scope = spfile
scope = both
For the value in question, scope = memory, Oracle will make the change specified by the alter system command for the life of the instance.
The next time the database is bounced, for any reason, the change will be reverted to the default value.
For scope=spfile the change made in the alter system command will take place starting from the next startup but will not affect the current instance.
If you want the alter system command to take place immediately you can use the scope = both value, which will make the change for the current instance and preserve it through any future bounces.'
