UnSuccessful Testing – TOR on LPAR 83 & AOR on LPAR 84 Test harness execution passes thru RST2 (TOR) to RUV1 (AOR) and receives error.

Environment

Release:
Component: CGTCPC

Cause

Running server transactions across LPARs using Direct Connect for CICS

Resolution

The TCPIP Direct Connect implementation needs to have the Listener and the Servers in the same LPAR. Specifically, in the same TCPIP Stack. Timeouts will occur because the server will not be able to find the Listeners socket and thus the Listener thinks the Server does not run.  This is a limitation of IBM TCP/IP Socket Interface.
