We have been able to ship relatively small packages without problems. A test of a larger package was attempted (71 elements, 111 outputs to be shipped).
The C1BMXNDM step got RC=8 with the following messages:
SCIC000I Connect:Direct - RC=00000008 MSG=SPQL005I NODE=<node>
SHORT TEXT => SPQL005I Process exceeds TCQ capacity
LONG TEXT => The submitted process would take more than 43 CIs in the TCQ.
The submit request is rejected.
SYSTEM ACTION: Processing Continues.
RESPONSE: The TCQ CISIZE must be increased to hold a process of this size. A COLD start must be performed when the TCQ CISIZE is changed.
Limitation is in IBM's product Connect:Direct.
