请教冷克隆时通道分配的写法

lujiaguai

唐sir:   做冷克隆，异地恢复run块如下写法,备份集很大的情况下，单通道很慢（见帖子底部），请教这种情况怎么增加通道分配的参数？
   查阅了文档 https://docs.oracle.com/html/E10643_07/rcmsynta004.htm，最后部分是用[size=11.6188px]DB_FILE_NAME_CONVERT，但我这里直接用db_create_file_dest。
   尝试过如下写法，不对。
   run {[size=11.6188px]ALLOCATE AUXILIARY CHANNEL c1 DEVICE TYPE disk;
[size=11.6188px]            [size=11.6188px]ALLOCATE AUXILIARY CHANNEL c2 DEVICE TYPE disk;
[size=11.6188px]            duplicate target database to orcl
          .
          .
          release channel c1;
          release channel c2;
          }
[size=11.6188px]     或者补上闪回区，也不对
[size=11.6188px]        run {[size=11.6188px]ALLOCATE AUXILIARY CHANNEL c1 DEVICE TYPE disk [size=11.6188px] TO '%F' [size=11.6188px];
[size=11.6188px]                 [size=11.6188px]ALLOCATE AUXILIARY CHANNEL c2 DEVICE TYPE disk [size=11.6188px] TO '%F'[size=11.6188px] [size=11.6188px];
[size=11.6188px]            duplicate target database to orcl
          .
          .
          release channel c1;
          release channel c2;
          }
