ERROR DESCRIPTION:
The Multiple Protocol Routing server (MPROUTE) will be upgraded
from z/OS level 2.2 to z/OS level 2.4.
LOCAL FIX:
N/A
PROBLEM SUMMARY:
****************************************************************
* USERS AFFECTED: All Users of z/VM MPRoute server. *
****************************************************************
* PROBLEM DESCRIPTION: *
****************************************************************
* RECOMMENDATION: APPLY PTF *
****************************************************************
The z/VM 6.4.0 MPRoute server intermittantly has adjacency
failures, loses connectivity, and never recovers.
PROBLEM CONCLUSION:
TEMPORARY FIX:
COMMENTS:
The Multiple Protocol Routing (MPRoute) server has been enhanced
and upgraded from z/OS level 2.2 to z/OS level 2.4. In
addition, support has been added to TCP/IP to monitor the
responsiveness of the MPRoute server, and terminate the MPRoute
server if it becomes unresponsive.
TCP/IP Messages and Codes
SRL GC24-6237-11 GC24-6330-01
The following messages have been added to Chapter 16, "TCP/IP
Server Messages",on page 481
DTCPDO509I
DTCPDO510I
DTCPDO509I TCP/IP determined that MPRoute was not responsive
for at least <maxinterval> seconds.
DTCPDO510I KillClient: Client <ServerID>
Explanation:
TCP/IP has determined that the MPRoute server <ServerID> has
been unresponsive for <maxinterval> seconds.
System action:
The MPRoute server is terminated. If the MPRoute server has been
specified on the AUTOLOG statement, TCP/IP will attempt to
restart the MPRoute server. Otherwise, restart the MPRoute
server.
System programmer response:
If an abend occurred, collect a dump of MPROUTE and contact the
IBM Software Support Center. For additional information,
including instructions on gathering documentation, see
diagnosing MPROUTE problems in "z/VM: TCP/IP Diagnosis Guide".

- In the section following 'MPRoute has the following
characteristics: ', add this bullet to the end of the list.

TCP/IP will monitor the responsiveness of
MPRoute and will terminate the MPRoute server if it becomes
unresponsive. The server will be restarted if it is in the
AUTOLOG list.
In Chapter 8, 'Configuring the MPRoute Server', section
'Configuration Steps for the MPRoute Server',
'Step 1. Update the TCP/IP server configuration file :
Autolog Considerations for MPROUTE'
Change the note at the end of Autolog Considerations for
MPROUTE to:
Note: When using only the OSPF protocol, the autostart feature
of AUTOLOG can be used as described above.
TCP/IP will monitor the responsiveness of MPRoute and will
terminate the MPRoute server if it becomes unresponsive.
MPRoute will be restarted if it is in the AUTOLOG list.
