ECO KIT SUMMARY:
An ECO kit exists for Reliable Transaction Router on OpenVMS VAX V6.1
through V7.1. This kit addresses the following problems:
o 14-8-144 RTR crash when ASYNC cable disconnected
Disconnecting a cable that was being used by an asynchronous
DECnet link to a remote machine could result in an ACP failure
when the transport marked the sockets as invalid. RTR has been
changed to handle this error by temporarily suspending all
network activity on the affected node. Network activity will
resume as soon as the network is found to be usable again.
o 14-8-154 Router crash when link to Frontend disconnected
Router ACPs configured to accept anonymous clients could under
circumstances fail when handling a network link loss event. This
has been corrected.
o 14-8-155 New environment variables for adjusting connection timeout
parameter
Two new environment variables have been created to give operators
greater discretion in determining how long to wait before retrying
a network connection attempt.
The RTR_TIMEOUT_CONNECT variable controls how long a connecting
node will wait for a response from the connectee to its link
initiation request. This value defaults to 60 seconds.
If the RTR_TIMEOUT_CONNECT period expires without a response from
the connectee, RTR will wait an additional period determined by
the RTR_TIMEOUT_CONNECT_RELAX variable. This variable defaults
to a value of 90 seconds. The purpose of the "relax" period is
to allow the connector to accept a connection request from the
connectee node, if any are forthcoming. It is important not to
set this value too low on Backends and Routers, as such machines
are likely to be receiving connection requests from many other
machines. On machines configured to use only the Frontend role,
however, you can safely set RTR_TIMEOUT_CONNECT_RELAX to just a
few seconds so that the node can be free to attempt to connect to
another router as quickly as possible.
The minimum value for RTR_TIMEOUT_CONNECT is 5 and the minimum
for RTR_TIMEOUT_CONNECT_RELAX is 1.
The following restrictions apply to this kit:
o 14-1-285: A temporary inconsistency in shadow server state can occur
during initial facility startup of a shadowed configuration. A
shadow server can erroneously remain in state "sec_act" until the
rest of the facility has been started.
o 14-3-67: An application's wakeup routine may be called more often
than necessary.
INSTALLATION NOTES:
The Reliable Transaction Router installation procedure uses the POLYCENTER
Software Installation Utility (PCSI). For details on using PCSI, refer to
the OpenVMS System Manager's Manual, Section "Installing with the POLYCENTER
Software Installation Utility".
The logical name PCSI$SOURCE is used to define the location of the software
kits you want to install. For example, if the Reliable Transaction Router
software is located in DISK1:[KITS], enter the following at the DCL prompt
(or include the line in the system manager's login command file):
$ DEFINE PCSI$SOURCE DISK1:[KITS]
When running the installation procedure for Reliable Transaction Router,
you can choose whether to install the ODBC Over RTR Oracle7 Server. This
is an RTR server used for supporting ODBC-enabled applications on Windows.
You should not install the ODBC Over RTR Oracle7 Server unless you already
have Oracle7 installed.
To start the installation, type the command:
$ PRODUCT INSTALL RTR
You will see a display similar to the following:
The following product has been selected:
DEC VAXVMS RTR V3.1-D176 [Available]
Do you want to continue? [YES]
Press . You may safely accept the installation default
options.
