5.2 Standard Monitor Pictures

Table 5–1 (Cont.) Standard Monitor Pictures

Picture name

Description

traffic

Displays a list of the links to other nodes. Shown for each link are: byte rate, packet
rate, message rate and congestion, in both directions. Average packets per second is
also shown.

trans

Displays transactions for a frontend, router and backend.

v2calls

Shows RTR Version 2 verb usage through the interoperability subsystem. The screen
layout is identical to the RTR Version 2 monitor calls picture.

xa

Displays XA counter information including success and failure as well as call and
readonly counters.

The following sections describe the more commonly used standard monitor
pictures in detail.

5.2.1 Monitor ACCFAIL (Link Acceptance Failures)

When configuring RTR it can happen that nodes sometimes fail to connect
up. Whilst the cause of the error can be viewed on the initiator side with the
MONITOR NETSTAT picture, it can be difficult to pinpoint the problem when
looking at the other end of the link. The monitor picture ACCFAIL can be used to
display the reason for the local node to refuse to accept connections. An example:

Some of the errors that can be displayed by ACCFAIL are:-

RTR_STS_NOTRECOGNISED - "node not recognized"

The local node has received a connection request over a link that is not
configured in any facility on the local machine. If you expected the connection
to succeed as the result of having a template link defined, check carefully the
names displayed in the monitor picture. These are the names obtained from
the network transport over which the link connection attempt was received,
and it is with these that a match with a template (wildcard specification)
link must succeed. Bear in mind that the name match is performed in a case
sensitive manner. Names corresponding to TCP links may or may nor contain
