After an upgrade to r11, the XTCNET parameter is no longer accepted for TYPE=EXECUTE transfers. It was accepted at release 3.1 and before. The message XCOMM0046E XTC PARAMETERS NOT SUPPORTED FOR TYPE=EXECUTE is displayed.
This is not a change to the product. In previous releases the XTCNET parameter was ignored for TYPE=EXECUTE transfers. At r11, an error message is now displayed since this parameter is not valid for TYPE=EXECUTE transfers. The CA XCOM server is required (and has always been required) to perform any XTC processing. TYPE=EXECUTE transfers do not use the CA XCOM server.
