IST1787I

Explanation
 VTAM® issues
this message as the first of a message group to display the results
of an HPR Route Test for puname. This HPR Route
Test was initiated in response to a DISPLAY  RTPS command with ID=puname or
TCID=tcid_value and TEST=YES being issued for the
RTP PU identified by puname. This message is the
first in a group of messages and the full description of the message
group follows the example.   IST1787I HPR ROUTE TEST RESULTS FOR RTP PU puname
 IST1788I NODE CP NAME    TG NUMBER  PARTNER CP NAME  INTERNODAL TIME
 IST1789I                                             (MILLISECONDS)

 IST1787I                  

                           puname is the RTP PU for which the Route Test
results are displayed.

 IST1788I This message serves as a header for message IST1788I to identify
the output columns in that message.

 IST1789I                                     

       This message shows that the internodal_time value is in milliseconds.

 IST1790I This message provides the data obtained by the Route Test. One
of these messages will be issued for each link (Transmission Group)
in the RTP pipe.
node_cpname is the CP name of the node owning
the Transmission Group(TG).  
tg_number is the negotiated TG number for this
RTP or UNKNOWN if the real TG information is not available.
partner_cpname is the CP name of the partner
node for this TG.
internodal_time is the time it took for a Route
Test packet to traverse this TG, in milliseconds, or ***NA*** if
this test packet did not return. Note: The sum of the internodal times
shown in the IST1790I messages might be as much as 1 ms less for each
hop in the RTP than the total RTP traversal time shown in message
IST1792I, because integer division might cause internodal times to
be truncated during calculation.

 IST1791I  This message will be issued for all nodes in the RTP pipe that
did not return a Route Test packet.
cpname is the CP name of the node that did
not return the Route Test packet.

 IST1792I                                     

              This message tells how long it took a Route Test packet to be
sent from this VTAM to the
other end of the RTP pipe.  
traversal_time is the total time in milliseconds
it took for a Route Test packet to travel from VTAM to the other end of the RTP pipe.

System action
 Processing continues.

Operator response
 Examine the internodal and traversal times
for each link (Transmission Group) to identify any links where the
traversal time is slow.   Route Test packets not returned would indicate
a problem with one or more of the links between this host node and
the node identified by IST1791I.  Path Switching for this RTP should
be automatically attempted by the system.

System programmer response
 None.
