Starting and Setting Up RTR
2.10 Network Protocol Selection on OpenVMS
2.10 Network Protocol Selection on OpenVMS
•
The default network transport protocol on OpenVMS is DECnet. You may
change the default to TCP/IP by removing this line from
$ DEFINE/SYSTEM RTR_PREF_PROT RTR_DNA_FIRST
If you are using TCP/IP, you will need to use the node-name prefix ''
if you specifically want DECnet transport to be used. This is required,
for example, when connecting to Version 2.2D ECO6 nodes as described
in Section 2.9.3 of these Notes, and Section 2.7 of the System Manager's
Manual.
If you are using DECnet as the default, you will need to use the node-name
prefix ''
If the value of the logical RTR_PREF_PROT is changed, the new value takes
effect only after RTR has been restarted.

Reliable Transaction Router Version 3.2 for OpenVMS can use either Compaq
TCP/IP Services for OpenVMS or TCPware Version 5.1 as the TCP/IP
transport layer.
2.11 Running RTR as a Service on Windows NT
Once the RTR as Service has been installed (see Installation Guide), RTR may
be started or stopped from the Control Panel / Services panel using the START
and STOP buttons provided.
•
To start RTR: Press the START button.
•
To stop RTR: Press the STOP button.
Pressing START and STOP or the reverse in quick succession (within
five or so seconds, depending on the speed of your computer) may cause
undesirable results. This is because the Service executes quickly, making
available the other action button, but the requested RTR action may
not have completed when the second action button is pressed. It is
therefore possible, for example, that the STOP action may be blocked
by an incomplete START action. Although the Service will claim to be
STOPped, RTR may in fact remain started. Pressing whichever action
button is functioning should repair the problem.
By default, RTR will not restart automatically at system reboot time. You can
change this by setting the Control Panel / Services entry for RTR.
Occasionally, an RTR process may continue to run after STOP has been pressed,
and subsequent START and STOP actions may have no effect or produce an
error. Under these circumstances, it will be necessary to intervene directly, as
a privileged (SYSTEM) user, to stop RTR. This can be done either using RTR
commands or with the Task Manager, or by rebooting.
