核心提示： 一个命令交叉验证磁盘和磁带备份的例子：CONFIGURE DEVICE TYPE sbt PARALLELISM 1;CONFIGURE DEFAULT DEVICE TYPE to sbt;CROSSCHECK BACKUP OF DATABASE;示例输出文件如下：allocated

一个命令交叉验证磁盘和磁带备份的例子：

CONFIGURE DEVICE TYPE sbt PARALLELISM 1;
CONFIGURE DEFAULT DEVICE TYPE to sbt;
CROSSCHECK BACKUP OF DATABASE;

示例输出文件如下：

allocated channel: ORA_SBT_TAPE_1
channel ORA_SBT_TAPE_1: sid=12 devtype=SBT_TAPE
channel ORA_SBT_TAPE_1: WARNING: Oracle Test Disk API

如果没有配置磁带备份设备，也可以手工执行分配通道：

ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE sbt;
CROSSCHECK BACKUP OF DATABASE;
