QUESTION NO: 186
Consider the following command:
Backup database plus archivelog delete input;
How many backup sets would be created by this command if the following were true:
Control-file auto backups were enabled.
The size of backup sets was not restricted.
One channel was allocated.
A. 1
B. 2
C. 3
D. 4
E. 5
Answer: D
考虑下面的命令：
Backup database plus archivelog delete input;
备份数据库加归档记录删除输入;
多少备份集通过该命令创建，如果以下是真实的：
Control-file auto backups were enabled. 启用控制文件自动备份。
The size of backup sets was not restricted.备份集的大小没有限制。
One channel was allocated.分配一个通道。
D. 4
The following backup sets would be created:
One for an archive log backup before the main backup.
One for the main backup. Since we are using a single channel with no backup-set size restriction, RMAN
would create a single backup set.
One for an archive log backup after the main backup.
One for the control-file autobackup.
将创建下面的备份集：
一个用于在主备份之前的一个归档日志备份。
一个用于主要的备份。由于我们使用的是一个没有备份集的大小限制的单一的通道， RMAN将创建一个单一
的备份集。
一个用于主备份后的归档日志备份。
