We see the message "TXPI 203 gethostbyname error" on different CA-XCOM Data Transport platforms from time to time. What, basically, does this mean?

Basically, it means that your IP-based XCOM transfer failed because IP couldn't get to the machine targeted by the transfer. A variety of things can cause this error. Two of the most common causes are:

  1. The IPNAME could not be resolved to an IP ADDRESS (possible configuration or Domain Name server problem).
  2. TCPIP is not available on the remote partner. ( Check that the TCPIP listener is running on the remote partner.)
