RMAN备份下开启并行与快照报错的小问题

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Helvetica} p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Helvetica; min-height: 13.0px}

--开启并行

configure device type disk parallelism 3;

--配置控制文件快照至集群的共享存储，节点间可以互相访问

CONFIGURE SNAPSHOT CONTROLFILE NAME TO '+HDD/snapcf_orcl.f';

--开启压缩备份集，并使用多通道进行备份，解决大数据下的备份空间与速度
