What is the meaning of return value 10054?
10054 is a TCPIP error that means 'connection reset by peer'. The reset could actually be from the local socket due to a connection failure, or could be a reset message passed back from the remote system. Unicenter CA-XCOM is passing the error back from TCP/IP. That is, the return value 10054 is not from CA-XCOM but from the IP socket. Usually the problem is related to the network set-up and/or TCP/IP configuration.
- Review the TXPI_TERM_TIMEOUT value on the initiating side to make sure it is long enough.
- Initiate transfers from both sides and see what happens.
- From NT or UNIX or LINUX, try a transfer to the loopback address (127.0.0.1). This way, XCOM will perform a transfer to itself. This will be done only with the local TCP/IP stack and the network is not involved. This helps to isolate malfunctions in one of the partner's sockets or in the network.
- Determine what TCP/IP window sizes you have defined for both partners. A conflict here can cause this problem. For example, if the partners are NT and z/OS, make sure the WINDOW size and the MTU values in the TCP/IP protocol configuration match on the two sides.
