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.

解决方案如下
从恢复区释放空间：
1、考虑改变RMAN保留策略。
2.使用备份恢复区命令备份文件第三设备磁盘，如磁盘。
3.增加磁盘空间，增加磁盘空间 db_recovery_file_dest_size 新空间的参数映射。
4、使用RMAN DELETE命令删除不必要的文件。如果操作系统命令用于删除文件，使用 RMAN CROSSCHECK和DELETE EXPIRED的命令。
第一种方法如下
