oracle归档错误

ORA-16038: log 2 sequence# 242 cannot be archived
ORA-19809: limit exceeded for recovery files
ORA-00312: online log 2 thread 1: '/opt/oracle/oradata/BEE/redo02.log'

解决办法:
办法1：扩大db_recovery_file_dest_size 空间
办法2：清理归档日志文件，释放空间
OS中删除db_recovery_file_dest下不用的归档文件，然后进入rman：

rman>crosscheck archivelog all;         //此处绝非crosscheck backup of archivelog all;

rman>delete expired archivelog all;       //此处绝非delete expired backup of archivelog all;

rman>delete obsolete;

办法3：直接关闭归档模式
