Auxiliary channels of Duplicate command using multiples RAC instances

Hi,

I've a question regarding the posibility to use multiples auxiliary channels distribuited between differents Rac instances.

I've this command.

connect target sys/xxxxx@target

connect auxiliary sys/xxxxx@CLONE2

run {

ALLOCATE CHANNEL c1 DEVICE TYPE DISK CONNECT='sys/xxxx@rac1';

ALLOCATE CHANNEL c2 DEVICE TYPE DISK CONNECT='sys/xxxx@rac2';

ALLOCATE CHANNEL c3 DEVICE TYPE DISK CONNECT='sys/xxxx@rac3';

ALLOCATE CHANNEL c4 DEVICE TYPE DISK CONNECT='sys/xxxxx@rac4';

ALLOCATE CHANNEL c5 DEVICE TYPE DISK CONNECT='sys/xxxxx@rac1';

ALLOCATE CHANNEL c6 DEVICE TYPE DISK CONNECT='sys/xxxxxx@rac2';

ALLOCATE CHANNEL c7 DEVICE TYPE DISK CONNECT='sys/xxxxxx@rac3';
