Hi.

Is there a way to force/configure rman to run on a specific network card?

    Not that I can see in any of the rman syntax.

    Nor would I care.

    What problem are you trying to solve? (and, no, how to assign rman to a specific NIC is not a problem, it is a pre-conceived technical "solution".

    You can use RMAN to backup and restore a local database only. Database storage or backup media can be remote but needs to appear as local, e.g. NFS. Hence RMAN does not have any business with network devices and it's up to the OS to provide storage access, and, for example, map remote storage as local media.

    Hi. thank you for reply.  I have two NICs, one (NIC1) for administration only and other one (NIC2) that i want to use only for the backup traffic to a EMC data domain server.

    When executing backup, i can see the traffics is starts on NIC1, that is slower thant NIC2.  I want to use only NIC2 for backup traffic.

    Again, RMAN doesn't know or care about your network adapter.  If you use EMC, chances are you use Powerpath or Multipath, and perhaps iSCSI or NFS (dNFS). From the perspective or RMAN it's local storage media. If you want traffic to go via a certain NIC you need to configure your network/OS accordingly, not RMAN.
