ARC1: Becoming the heartbeat ARCH
Errors in file /u01/app/oracle/diag/rdbms/prod1/PROD1/trace/PROD1_ora_10708.trc:
ORA-19815: WARNING: db_recovery_file_dest_size of 2097152000 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.

USER (ospid: 10708): terminating the instance due to error 16038

System state dump requested by (instance=1, osid=10708), summary=[abnormal instance termination].
System State dumped to trace file /u01/app/oracle/diag/rdbms/prod1/PROD1/trace/PROD1_diag_10658_20180812011057.trc

Instance terminated by USER, pid = 10708

解決方法如下
下列選項可從恢復區域釋放空間：
1、考慮改變RMAN保留策略。
2、使用備份恢復區域命令備份檔案第三裝置磁碟如磁碟。
3、新增磁碟空間並增加 db_recovery_file_dest_size 引數對映新的空間。
4、使用RMAN DELETE命令刪除不必要的檔案。如果作業系統命令用於刪除檔案，然後使用 RMAN CROSSCHECK和DELETE EXPIRED的命令。

第一種方法如下
