Summary:

This error message indicates that XCOM is attempting a transfer but it is failing because VTAM/SNA can not establish or maintain a connection. A Session needs to be established between partners before a transfer can begin. The RC zz FDBK2 yy SENSE CODE nnnn refers to the specific reason for the failure. This error could be the result of incorrect parameter values being passed to the APPC or VTAM, or conditions present in the network at the time of the transfer or attempted transfer.
