RMAN - 如何在备份标签中添加日期

Question

我知道 RMAN 的默认设置是以以下格式添加日期：TAGYYYYMMDDTHHMMSS, 但如果我想要这样的东西：BKP_FULL_11112019。我怎么做？我尝试使用%T但它不起作用。

我想做这样的事情：

backup as compressed backupset incremental level 0 database tag = 'BKP_FULL_current_date_here'

其中 current_date_here 必须是当前日期。

在脚本中构造标记并将其作为替换变量传递。Linux 上的 bash 示例：

$ cat BKP_FULL.rcv
run
{
  backup as compressed backupset incremental level 0 database tag '&1';
}
$ export MYTAG='BKP_FULL_'$(date +%Y%m%d%H%M%S)
$ echo $MYTAG
BKP_FULL_20191111195400
$ rman target / cmdfile=BKP_FULL.rcv using $MYTAG
