Add the following lines to the /etc/services file

txpi              8044/tcp      # xcom
txpis             8045/tcp      # xcom (r11 only)

Create two files in /etc/xinetd.d called txpi and txpis

root@linux:~ # vi /etc/xinetd.d/txpi
# default: on
# description: The Unicenter CA-XCOM Data Transport Server.
service txpi
{
disable = no
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/lib/xcom/xcomtcp
server_args = REMOTE 0
}

root@linux:~ # vi /etc/xinetd.d/txpis
# default: on
# description: The Unicenter CA-XCOM Data Transport Server.
service txpis
{
disable = no
socket_type = stream
protocol = tcp
wait = no
user = root
server = /usr/lib/xcom/xcomtcp

Making the daemon automatically start on startup

root@linux:~ # echo “xcom:3:once:/usr/sbin/xcomd” >> /etc/inittab
root@linux:~ # grep xcom /etc/inittab
