今天一上班，登陆测试库，出现
ORA-00257: archiver error. Connect internal only, until freed.
看alert.log 文件，出现如下：

************************************************************************
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.
************************************************************************
Archiver process freed from errors. No longe
很明显是db_recovery_file_dest 的空间满了。
执行rman> delete archivelog until time 'sysdate-1' ;
删除不需要的archive log文件。一切OK。
