使用下面脚本检查数据库的备份记录,发现数据库中RMAN的备份是成功的。
SET LINESIZE 720;
COL CON_ID FOR 9999
COL STATUS FORMAT A9;
COL START_TIME FOR A19;
COL END_TIME FOR A19;

使用list backup of controlfile也能查看到控制文件的备份信息
RMAN> list backup of controlfile;
仔细分析日志后,发现其实报错信息"Backup of managed control file failed."并不是RMAN备份控制文件时失败了,而是HP DP(Data Protector)软件不能备份控制文件,也就是说问题还是在于HP DP,后面搜索了相关资料,结合报错信息"Script failed. Cannot get information from remote host.",发现引起这个错误的原因在于hostame不能解析成当前服务器的IP地址,具体原因:数据库迁移过程本来需要切换IP,后面由于一些原因,没有切换IP,使用新的IP地址,而由于折腾原因,大家都忘记了要修改/etc/hosts了,从而导致HP DP(Data Protector)的作业报这个错误。
