RMAN> duplicate target database for standby nofilenamecheck

到主库validate backupset同样的错误发生。

备份日志中没有错误，RAC两个节点分别分配了4个通道。

如下是两个管道：
allocate channel dev2 type disk connect sys/xxx@node1;
allocate channel dev5 type disk connect sys/xxx@node2;

尝试减少管道数至2*2，出现了另外一个错误：

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of validate command on dev1 channel at 12/02/2009 12:03:45
ORA-19660: some files in the backup set could not be verified
ORA-19661: datafile 26 could not be verified
ORA-19661: datafile 47 could not be verified
ORA-19661: datafile 16 could not be verified
ORA-19661: datafile 2 could not be verified

最终无果，只得做单节点的rman备份，validate通过，duplicate没有问题。
