Errors in file /u01/app/oracle/diag/rdbms/orcl/orcl/trace/orcl_ora_2653.trc:
ORA-19815: WARNING: db_recovery_file_dest_size of 4070572032 bytes is 100.00% used, and has 0 remaining bytes available.
************************************************************************
You have following choices to free up space from 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.

异常原因：
快速恢复区使用率达到100%.
处理过程：
将数据库启动到mount状态后，
1、系统层面删除快速恢复区的归档日志.
2、进入rman，crosscheck archivelog all
3、delete expired archivelog all
4、alter system set db_recovery_file_dest_size=25g;

此后成功开启数据库.
