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
